In 1797, Levi Dickenson perfected the earlier broom after noticing his wife’s did not sweep and bristles were falling off. The support and locomotive functions, which were performed by the wheels of a typical railway vehicle, are performed by electromagnets that are mounted to the magnetic levitation train. [63] The manipulation lever 19 functions to selectively control the forward and backward movements of the train body 2. When a rear door of the train body 2 is opened in the state in which the tunnel 26 is maintained in a vacuum, the train body 2 is pushed by the atmospheric pressure acting on the interior of the tunnel 26, so that an auxiliary driving The upper guide rails are mounted to the left and right portions of the train body opposite the guides. In this state, when the proximity sensors are located over the detection plates 16a, current flows to the field coils 11 due to the operation of the proximity sensors 16, so the an electromagnetic field is generated, and thus the field coils 11 are magnetized. The cleaning process was still tedious, and people searche… Thanks to these advantages, the magnetic levitation train is expected to be used in urban areas as a next-generation transportation means. [90] The magnetic levitation train according to the present invention can greatly contribute to the commercialization thereof if it is integrated with existing magnetic levitation trains that are under research and development. [citation needed], Salter pointed out how such a system would help reduce the environmental damage being done to the atmosphere by aviation and surface transportation. [69] Meanwhile, as shown in FIGS. [86] Furthermore, when the train body 2 passes through the vacuumed tunnel 26, the front and rear partition walls 27 are automatically opened and closed. [84] In greater detail, the field coils 21 are mounted in the braking box 22 constituting the braking-generating means 20. [74] In FIG.

Disclosure of Invention AUTOMATIC VALVE FOR TRACK-SANDERS. Gravity would further accelerate the departing train down to cruise level. This air movement knocked dirt off the filter cone and sent it to the vacuum's pan below. Others toilet systems get catapulted to speeds of more than 370 miles per hour aboard the sophisticated Maglev train, where light weight and sturdiness are essential. [77] When an engineer rotates the manipulation lever 19 in the forward direction to make the train body move forwards, 2, the slide frame 17 is guided by the guide frames 18 to slide forwards, and thus the proximity sensors 16, which are mounted on the slide frame 17 at regular intervals, are located slightly ahead of the field coils 11. O'Neill planned to build a network of stations connected by these tunnels, but he died two years before his first patent on it was granted. Brief Description of Drawings [12] FIG. In this case, the rack gear 25b, which is engaged with the pinion 25 a, is lowered or suddenly lowered, so that the braking box 22, which is connected with the rack gear 25b, is lowered or suddenly lowered to the lower guide rail 8, and thus the field coils 21 are magnetized to have polarities opposite those of the permanent magnets 9 and 10 by the permanent magnets 9 and 10 and are attracted by magnetic force. The accompanying drawings are provided to help understanding of various embodiments. Accordingly, when the train body 2 travels on the rails, the train body 2 travels in the state in which it is levitated from the upper guide rails 3, thus being safely guided. With manifold and distributor (Class 123/90.13) Hybrid valve train system. Several train systems using maglev have been developed over the years, with most operating over relatively short distances. Accordingly, the possibility of the train body being moved off the track can be minimized. the force that is obtained when one field coil 11 and two permanent magnets 9 and 10, which are mounted to the lower guide rail 8 so as to be spaced apart from each other by a predetermined distance, are repelled from each other in a narrow gap by mutual magnetic force, thus not only acquiring a large amount of torque but also reducing energy costs, compared with conventional magnetic levitation trains. 596,575, dated January 4, … A valve 23 is operated [57] Furthermore, the drive unit 4 includes a drive means 7, which is mounted under the train body 2, and a lower guide rail 8 which is configured to provide a driving force for moving the train body 2 forwards or backward in conjunction with the drive means 7 and to safely guide the train body 2. In 1888, Michel Verne, son of Jules Verne, imagined a submarine pneumatic tube transport system that could propel a passenger capsule at speeds up to 1,800 km/h (1,100 mph) under the Atlantic Ocean (a transatlantic tunnel) in a short story called "An Express of the Future". [88] Furthermore, according to the present invention, the upper guide rails 3 and the guides 5 mounted to the upper portion of the train body are made of permanent magnets. [4] The magnetic levitation train according to claim 1, wherein the braking-gen erating means (20) comprises: a braking box (22) provided with a plurality of field coils (21) mounted on a rear side of the train body (2); a braking motor (23) and a sudden braking motor (23a) rotated in forward and backward directions by manipulation of a braking motor switch (19a) and a sudden braking motor switch (29); and a connection member (25) comprising a pinion (25a) fastened to respective motor shafts (24, 24a) of the braking motor (23) and the sudden braking motor (23a), and a rack gear (25b) engaged with the pinion (25a) and configured such that one end thereof is fastened to the braking box (22); wherein, when the train body (2) is normally or suddenly braked, the field coils (21) in the braking box (22) connected with one end of the connection member. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph). That is, when the opening detection sensor 30, which is mounted in the front portion of the train body 2, detects the detection part 32 mounted in the tunnel 26, the front partition wall 27, which is located in the direction in which the train body 2 travels is opened. [10] However, the concept itself he called Magnetic Flight. [5][6] He later published a vactrain concept in 1914 in the book Motion without friction (airless electric way). An early maglev train was described in U.S. Patent 3,158,765, "Magnetic system of transportation", by G. R. Polgreen (25 August 1959). At the moment, the top speed for a hyperloop train is predicted to reach around 760 mph. [83] Furthermore, when it is necessary to decrease the speed of the traveling train body 2 and to brake the traveling train body 2, the braking-generating means 20, which is mounted on the rear side of the train body 2, must be operated by the manipulation of the braking motor switch 19a mounted on the manipulation lever 19 must be.

SPECIFICATION forming part of Letters Patent No. In the case where the braking motor switch 19a or the sudden braking motor switch 29 is selectively manipulated, the braking motor 23 or the sudden braking motor 23a are driven in the forward direction, and thus the pinion 25a, which is fastened to the motor shafts 24 and 24a, is rotated at high speed. In this state, when the proximity sensors are located over the detection plates 16a, current flows to the field coils 11 due to the operation of the proximity sensors 16, and thus an electromagnetic field is generated. The guides are mounted on the left and right sides of the upper portion of a train body. [55] To this end, as shown in FIGS. [9] To this end, the present invention provides a magnetic levitation train, including: guides mounted on the left and right sides of the upper portion of a train body and made of permanent magnets; upper guide rails mounted to the left and right portions of the train body opposite the guides and made of permanent magnets, the permanent magnets having a magnetic polarity identical to that of the guides; a drive unit mounted under the train body and provided with a drive means and a lower guide rail; plural pairs of permanent magnets mounted on the left and right sides of the lower guide rail so as to be opposite each other, each pair of permanent magnets being spaced apart from the neighboring pairs of permanent magnets by a predetermined distance and being magnetized to have opposite polarities; field coils located between the permanent magnets and fixedly mounted below the train body; and a guide means mounted on a lower end of the field coils to be guided into the lower guide rail; wherein the drive means comprises the permanent magnets mounted on the left and right sides of the lower guide rail so as to be spaced apart from each other by the predetermined distance, field coils mounted below the train body so as to be spaced apart from each other at regular intervals, proximity sensor mounted at regular intervals on a slide frame, which is guided by guide frames fixedly mounted under the train body and is controlled to slide forward and backward by the manipulation of a manipulation lever, and detection plates arranged in zigzag fashion along with the permanent magnets which are mounted on the left and right sides of the lower guide rail, and wherein a braking-generating means is mounted to one end of the train body so as to brake the train body and to generate electricity. 5, the proximity sensors 16 are mounted at regular intervals on a slide frame 17, which is located under the train body 2 and which is configured to slide forwards and backwards below the train body 2 when the train body 2 is moved forward or backward or when the train body 2 is braked. Each pair of permanent magnets 9 and 10 are spaced apart from the neighboring pairs of permanent magnets, and are magnetized to have opposite polarities. Accordingly, in order to afford commercialization, it is urgently required to develop a magnetic levitation train that can solve all the above-described problems. [12], ET3 claim to have achieved some work that resulted in a patent on "evacuated tube transport technology" which was granted in 2009. Technical Problem, [7] Accordingly, the present invention is directed to provide a magnetic levitation train that can solve various problems occurring in existing magnetic levitation trains and, more particularly, to provide a new type of magnetic levitation train which not only can achieve excellent stability when traveling but also which can travel at high speed and, in addition, can play a role in saving energy, thus greatly contributing to the commercialization of magnetic levitation trains. [citation needed], On November 18, 1991, Gerard K. O'Neill filed a patent application for a vactrain system. [64] When the location of the slide frame 17 is controlled, the locations of the proximity sensors 16 mounted on the slide frame 17 at regular intervals change with respect to the field coils 11 that are fixedly mounted below the train body 2, and thus the field coils 11 are placed in a nonpolar state or are magnetized to have N and S polarities due to the electromagnetic field of the field coils 11. Search and read the full text of patents from around the world with Google Patents, and find prior art in our index of non-patent literature. Google has many special features to help you find exactly what you're looking for. This figure presents the amount of water (m 3) saved with Evac vacuum toilets compared to traditional gravity toilets since the … [11] Furthermore, when traveling, the train body is reliably supported by the upper guide rails in a levitated state, and is guided such that the lateral shaking thereof is prevented from occurring thanks to the reliable drive of the lower guide rail, so that excellent traveling stability and high-speed traveling can be achieved. [8] The present invention provides a magnetic levitation train, which can achieve excellent stability, can travel at high speed, and can minimize energy costs. In 1955, Polish science-fiction writer Stanisław Lem in a novel The Magellan Nebula wrote about intercontinental vactrain called "organowiec", which moved in a transparent tube at a speed higher than 1,666 km/h (1,035 mph). In this case, the slide frame 17 is greatly moved, so that the proximity sensors 16 are also greatly moved forwards or backwards compared with the field coils 11. slightly ahead of the field coils 11. EP, Kind code of ref document: The distance between London and New York is 3,466 miles, as the crow flies. [2] Currently, research into magnetic levitation trains is ongoing. Later in April 1962, the vactrain appears in the story "Mercenary" by Mack Reynolds,[7] where he mentions Vacuum Tube Transport in passing. On his train ride home, that very paper sparked his great idea for filtration. The transit tube would remain at least 300 m (1,000 ft) below the ocean surface to avoid water turbulence. Accordingly, the train body 2 can be normally braked or can be moved forwards or backwards (refer to FIGS. The basic plan is, well, as old as the enabling patent, US Patent 5950543, whose description is quite thorough. 3 is a sectional view showing the construction of an example of the upper and lower guide rails of the magnetic levitation train according to the present invention; [15] FIG. In order to commercialize such magnetic levitation trains, a large number of nations are devoted to their research and development. A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. In August 2013 Elon Musk, CEO of Tesla and SpaceX, published the Hyperloop Alpha paper, proposing and examining a route running from the Los Angeles region to the San Francisco Bay Area, roughly following the Interstate 5 corridor. [10], James R. Powell, co-inventor of superconducting maglev in the 1960s, has since 2001 led investigation of a concept for using a maglev vactrain for space launch (theoretically two orders of magnitude less marginal cost than present rockets), where the StarTram proposal would have vehicles reach up to 14,300 to 31,500 km/h (8,900 to 19,600 mph) within an acceleration tunnel (lengthy to limit g-forces), considering boring through the ice sheet in Antarctica for lower anticipated expense than in rock. He estimated the trains could reach speeds of up to 4,000 km/h (2,500 mph) – about five times faster than a jet airliner – if the air was evacuated from the tunnels. 18 is a diagram showing a circuit configured by the braking-generating means of the magnetic levitation train according to the present invention. Industrial Applicability. Push-pull operation can be achieved in the manner shown in FIG. Vacuum Brake Fittings and Pipes 0 Gauge Chassis kits and Accessories for scratchbuilders and kit modification. 14 and 15). When it is necessary to suddenly brake the traveling train body 2, the sudden braking can be achieved by the manipulation of the sudden braking motor switch 29. [15] The Hyperloop concept has been explicitly "open-sourced" by Musk and SpaceX, and others have been encouraged to take the ideas and further develop them. 17 is a diagram showing a circuit configured by the manipulation lever, which functions to control the forward and backward drive of the drive means of the magnetic levitation train according to the present invention, and proximity sensors; and [29] FIG. 11 to 13. The connection member 25 includes a pinion 25 a, which is fastened to the motor shaft 24 of the braking motor 23, which can be rotated in the forward and backward directions, and a rack gear 25b, which is engaged with the pinion 25a. 14 to 15, the upper guide rails 3 and the drive unit 4, through which the train body 2 according to the present invention pass, are mounted in a tunnel 26, which is maintained in a vacuum by the discharging of air to the outside. [30] , [35] 8: lower guide rail 9,10: permanent magnet, [38] 15: permanent magnet 16: proximity sensor, [39] 16a: detection plate 17: slide frame, [40] 18: guide frame 19: manipulation lever, [51] 32,33: detection part 08854978, Country of ref document: [2], The vactrain proper was invented by Robert Goddard as a freshman at Worcester Polytechnic Institute in the United States in 1904. [1] A magnetic levitation train, comprising: guides (5) mounted on left and right sides of an upper portion of a train body (2) and made of permanent magnets; upper guide rails (3) mounted to left and right portions of the train body (2) opposite the guides (5) and made of permanent magnets, the permanent magnets having a magnetic polarity identical to that of the guides (5); a drive unit (4) mounted under the train body (2) and provided with drive means, (7) and a lower guide rail (8); plural pairs of permanent magnets (9, 10) mounted on left and right sides of the lower guide rail (8) so as to be opposite each other, each pair of permanent magnets (9, 10) being spaced apart from the neighboring pairs of permanent magnets (9, 10) by a predetermined distance and being magnetized to have opposite polarities; field coils (11) located between the permanent magnets (9, 10) and fixedly mounted below the train body (2); and guide means (12) mounted on a lower end of the field coils (11) to be guided into the lower guide rail (8); wherein the drive means (7) comprises the permanent magnets (9, 10) mounted on the left and right sides of the lower guide rail (8) so as to be spaced apart from each other by the predetermined distance, field coils (11) mounted below the train body (2) so as to be spaced apart from each other at regular intervals, proximity sensor (16) mounted at regular intervals on a slide frame (17), which is guided by guide frames (18) fixedly mounted under the train body (2) and is controlled to slide forward and backward by manipulation of a manipulation lever (19), and detection plates (16a) arranged in zigzag fashion along with the permanent magnets (9, 10) which are mounted on the left and right sides of the lower guide rail (8), and wherein braking-generating means (20) is mounted to one end of the train body. In 1797, Levi Dickenson perfected the earlier broom after noticing his wife’s did not sweep and bristles were falling off. The support and locomotive functions, which were performed by the wheels of a typical railway vehicle, are performed by electromagnets that are mounted to the magnetic levitation train. [63] The manipulation lever 19 functions to selectively control the forward and backward movements of the train body 2. When a rear door of the train body 2 is opened in the state in which the tunnel 26 is maintained in a vacuum, the train body 2 is pushed by the atmospheric pressure acting on the interior of the tunnel 26, so that an auxiliary driving The upper guide rails are mounted to the left and right portions of the train body opposite the guides. In this state, when the proximity sensors are located over the detection plates 16a, current flows to the field coils 11 due to the operation of the proximity sensors 16, so the an electromagnetic field is generated, and thus the field coils 11 are magnetized. The cleaning process was still tedious, and people searche… Thanks to these advantages, the magnetic levitation train is expected to be used in urban areas as a next-generation transportation means. [90] The magnetic levitation train according to the present invention can greatly contribute to the commercialization thereof if it is integrated with existing magnetic levitation trains that are under research and development. [citation needed], Salter pointed out how such a system would help reduce the environmental damage being done to the atmosphere by aviation and surface transportation. [69] Meanwhile, as shown in FIGS. [86] Furthermore, when the train body 2 passes through the vacuumed tunnel 26, the front and rear partition walls 27 are automatically opened and closed. [84] In greater detail, the field coils 21 are mounted in the braking box 22 constituting the braking-generating means 20. [74] In FIG. [citation needed], Trains were to require no couplers, each car being directly welded, bolted, or otherwise firmly connected to the next, the route calling for no more bending than the flexibility of steel could easily handle. This pack contains sufficient parts to 'convert' one wagon to a vacuum braked vehicle; it contains Dean/Churchward short brake lever, brackets and rodding, vacuum … George. 2 is a front sectional view showing the construction of a modification of the magnetic levitation train according to the present invention; [14] FIG. [56] Although not shown, the upper guide rails 3 may be mounted on the left and right upper ends of a tunnel structure, the upper portion of which is opened, without using any supports 6. Disclosure of Invention AUTOMATIC VALVE FOR TRACK-SANDERS. Gravity would further accelerate the departing train down to cruise level. This air movement knocked dirt off the filter cone and sent it to the vacuum's pan below. Others toilet systems get catapulted to speeds of more than 370 miles per hour aboard the sophisticated Maglev train, where light weight and sturdiness are essential. [77] When an engineer rotates the manipulation lever 19 in the forward direction to make the train body move forwards, 2, the slide frame 17 is guided by the guide frames 18 to slide forwards, and thus the proximity sensors 16, which are mounted on the slide frame 17 at regular intervals, are located slightly ahead of the field coils 11. O'Neill planned to build a network of stations connected by these tunnels, but he died two years before his first patent on it was granted. Brief Description of Drawings [12] FIG. In this case, the rack gear 25b, which is engaged with the pinion 25 a, is lowered or suddenly lowered, so that the braking box 22, which is connected with the rack gear 25b, is lowered or suddenly lowered to the lower guide rail 8, and thus the field coils 21 are magnetized to have polarities opposite those of the permanent magnets 9 and 10 by the permanent magnets 9 and 10 and are attracted by magnetic force. The accompanying drawings are provided to help understanding of various embodiments. Accordingly, when the train body 2 travels on the rails, the train body 2 travels in the state in which it is levitated from the upper guide rails 3, thus being safely guided. With manifold and distributor (Class 123/90.13) Hybrid valve train system. Several train systems using maglev have been developed over the years, with most operating over relatively short distances. Accordingly, the possibility of the train body being moved off the track can be minimized. the force that is obtained when one field coil 11 and two permanent magnets 9 and 10, which are mounted to the lower guide rail 8 so as to be spaced apart from each other by a predetermined distance, are repelled from each other in a narrow gap by mutual magnetic force, thus not only acquiring a large amount of torque but also reducing energy costs, compared with conventional magnetic levitation trains. 596,575, dated January 4, … A valve 23 is operated [57] Furthermore, the drive unit 4 includes a drive means 7, which is mounted under the train body 2, and a lower guide rail 8 which is configured to provide a driving force for moving the train body 2 forwards or backward in conjunction with the drive means 7 and to safely guide the train body 2. In 1888, Michel Verne, son of Jules Verne, imagined a submarine pneumatic tube transport system that could propel a passenger capsule at speeds up to 1,800 km/h (1,100 mph) under the Atlantic Ocean (a transatlantic tunnel) in a short story called "An Express of the Future". [88] Furthermore, according to the present invention, the upper guide rails 3 and the guides 5 mounted to the upper portion of the train body are made of permanent magnets. [4] The magnetic levitation train according to claim 1, wherein the braking-gen erating means (20) comprises: a braking box (22) provided with a plurality of field coils (21) mounted on a rear side of the train body (2); a braking motor (23) and a sudden braking motor (23a) rotated in forward and backward directions by manipulation of a braking motor switch (19a) and a sudden braking motor switch (29); and a connection member (25) comprising a pinion (25a) fastened to respective motor shafts (24, 24a) of the braking motor (23) and the sudden braking motor (23a), and a rack gear (25b) engaged with the pinion (25a) and configured such that one end thereof is fastened to the braking box (22); wherein, when the train body (2) is normally or suddenly braked, the field coils (21) in the braking box (22) connected with one end of the connection member. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph). That is, when the opening detection sensor 30, which is mounted in the front portion of the train body 2, detects the detection part 32 mounted in the tunnel 26, the front partition wall 27, which is located in the direction in which the train body 2 travels is opened. [10] However, the concept itself he called Magnetic Flight. [5][6] He later published a vactrain concept in 1914 in the book Motion without friction (airless electric way). An early maglev train was described in U.S. Patent 3,158,765, "Magnetic system of transportation", by G. R. Polgreen (25 August 1959). At the moment, the top speed for a hyperloop train is predicted to reach around 760 mph. [83] Furthermore, when it is necessary to decrease the speed of the traveling train body 2 and to brake the traveling train body 2, the braking-generating means 20, which is mounted on the rear side of the train body 2, must be operated by the manipulation of the braking motor switch 19a mounted on the manipulation lever 19 must be.
