[67] Furthermore, in addition to the braking motor 23, a sudden braking motor 23a is additionally mounted. Furthermore, in the above-described existing magnetic levitation train, the gap between the rails and the train is wide. | Evacuated Tube Transport Technologies", "Here are the Hyperloop pods competing in Elon Musk's big race later this year", "Here's a first look at the SpaceX Hyperloop test track", Worcester Polytechnic Institute page discussing Goddard's achievements, Experimental and prototype high-speed trains (category), https://en.wikipedia.org/w/index.php?title=Vactrain&oldid=995709897, Articles needing additional references from April 2018, All articles needing additional references, Articles with unsourced statements from April 2018, Creative Commons Attribution-ShareAlike License, This page was last edited on 22 December 2020, at 13:51. Accordingly, the train body 2, to which the field coils 11 are fixedly mounted, can be moved forwards. [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. Using Vacuum as an Atmosphere. [13] They presented their idea 2013 on public stage.[14]. 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. 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. 18, reference numeral 34 indicates a speed sensor, and reference numeral 35 indicates a power interruption sensor. [85] Meanwhile, the present invention is designed such that the rails are mounted in the tunnel 26 so that the train body 2 can travel, thus enabling traveling at high speed by minimizing the air resistance. 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 selectively travel forwards or backwards.

[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. [citation needed], A route through the Northeast Megalopolis was laid out, with nine stations, one each in Washington DC, Maryland, Delaware, Pennsylvania, New York, Rhode Island, Massachusetts, and two in Connecticut. [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. A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. Best Mode for Carrying out the Invention. The cleaning process was still tedious, and people searche… In 1909, Russian professor Boris Weinberg [ru] built the world's first model of his proposed version of the vactrain at Tomsk Polytechnic University. [52] A magnetic levitation train according to the present invention may be configured as shown in FIGS. An air pump 20, labelled "PUMP", with flow ports 64, pressurizes the pressure vessel 21 while drawing a vacuum in the vacuum vessel 22. 12 is a sectional view illustrating the operation of the braking-generating means, 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.

Introduction The vacuum brake was, for many years, used in place of the air brake as the standard, fail-safe, train brake on railways in the UK and countries whose railway systems were based on UK practice. 4 is a sectional view showing the construction of another example of the upper and lower guide rails of the magnetic levitation train according to the present invention; [16] FIG. 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. The tunnel would maintain a partial vacuum to minimize drag. [1] The present invention relates to a magnetic levitation train, which enables a train body to be slightly levitated from a rail by the repulsive force of magnets and, at the same time, generates a drive force in the longitudinal direction of the rail, thus enabling high-speed traveling. In 1799, George Medhurst of London conceived of and patented an atmospheric railway that could convey people or cargo through pressurized or evacuated tubes. [citation needed], Starting in the late 1970s and early 1980s, the Swissmetro was proposed to leverage the invention of the experimental German Transrapid maglev train, and operate in large tunnels reduced to the pressure altitude of 21,000 m (68,000 ft) at which the Concorde SST was certified to fly. 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. [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. The American Planetran would establish transcontinental subway service in the United States and provide a commute from Los Angeles to New York City in one hour. The chamber's door to the tube would be opened, and enough air admitted behind to accelerate the train into the tube. 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. Accordingly, the force that is required to drive the train body 2 can be assisted by the difference between vacuum and atmospheric pressure. In this case, the train, having field coils, travels in a levitated state in which the train is spaced part from the rails by a predetermined distance. The distance between London and New York is 3,466 miles, as the crow flies. A guide means 12 is mounted to a lower end of the field coils 11 so as to prevent the train body 2 from colliding with the lower guide rail 8 when traveling and to minimize the lateral shaking of the train body 2. 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. Accordingly, when it is necessary to suddenly brake the train body 2, the sudden braking motor 23a is driven to rotate at high speed, and thus the sudden braking can be achieved. [2], The vactrain proper was invented by Robert Goddard as a freshman at Worcester Polytechnic Institute in the United States in 1904. 13 is a front sectional view showing the construction of the braking-generating means, which is mounted to the magnetic levitation train according to the present invention; [25] FIG. This combination of modified (shallow) gravity train and atmospheric railway propulsion would consume little energy but limit the system to subsonic speeds, hence initial routes of tens or hundreds of miles or kilometers rather than transcontinental distances were proposed. 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. 16, thus braking the train body 2. As a result, the field coils 11 are magnetized. [69] Meanwhile, as shown in FIGS. A spring system: James Newall, carriage builder to the Lancashire and Yorkshire Railway, in 1853 obtained a patent for a system whereby a rotating rod passing the length of the train was used to wind up the brake levers on each [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. In this case, each of the field coils 11 is magnetized to have the same polarities as those of its neighboring permanent magnets among the permanent magnets 9 and 10 that are mounted on the left and right sides of the lower guide rail 8 so as to be spaced apart from each other by a predetermined distance, and thus a repulsive force acts between them, while each of the field coils 11 is magnetized to have polarities opposite those of permanent magnets that are located behind a corresponding field coil, and thus an attractive force acts between them. The operation of the magnetic levitation train 1 is described in detail below. [60] The guide means 12 may be configured such that a bearing 13 is mounted to the lower end of the field coils 11, as shown in FIGS. The permanent magnets are mounted on the left and right sides of the lower guide rail so as to be opposite each other. A magnetic levitation train is provided. [79] Furthermore, when the manipulation lever 19 is rotated in the backward direction to make the train body 2 move forwards, as shown in FIGS. The upper guide rails 3, which have the same polarity as that of the permanent magnets constituting the guides 5, are mounted so as to be supported by respective supports 6. 11 is a sectional view showing the construction of a braking-generating means, which is mounted to the magnetic levitation train according to the present invention; [23] FIG. 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. AUTOMATIC VALVE FOR TRACK-SANDERS. A penis pump is one of a few treatment options for the inability to get or maintain an erection sufficient for sex (erectile dysfunction). [87] As described above, according to the present invention, the train body 2 travels along the vacuumed tunnel 26, and thus the decrease of the traveling acceleration performance of the train body 2 due to the air resistance of the train body 2 can be minimized. [75] The magnetic levitation train 1 according to the present invention can travel at high speed by enabling the train body 2 to be levitated from the upper guide rails 3 by a predetermined distance using auxiliary driving force attributable to magnetic repulsive force and atmospheric pressure. [71] In order to automatically control the opening and closing operations of the partition walls 27 mounted in the tunnel 26, an opening detection sensor 30 and a closing detection sensor 31 are mounted in the respective front and rear ends of the train body 2, and detection parts 32 and 33, which are detected by the opening and closing detection sensors 30 and 31, are mounted close to the partition walls 27, which are mounted in the tunnel 26 (refer to FIG. 18. The sliding of the slide frame 17 can be controlled in such a way that the slide frame 17 is guided on guide frames 18 in which respective bearings are provided. which is mounted to the magnetic levitation train according to the present invention; [24] FIG. 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". [citation needed], On November 18, 1991, Gerard K. O'Neill filed a patent application for a vactrain system. The railway would have both an inner evacuated tube and an outer tunnel. This figure presents the amount of water (m 3) saved with Evac vacuum toilets compared to traditional gravity toilets since the … reverse operations of the train body 2, and the sudden braking motor switch 29, which is used to brake or suddenly brake the train body 2, are mounted in the control room of the train body 2. 16 is a view showing the construction of a 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; [28] FIG. 5 is a view showing the construction of a slide frame, which is mounted in the lower portion of the magnetic levitation train according to the present invention; [17] FIG. Between 1984 and 1995 the first commercial maglev system was developed in Great Britain as a shuttle between the Birmingham airport and a nearby rail station, some 600 metres (about 1,970 feet) away. Thanks to these advantages, the magnetic levitation train is expected to be used in urban areas as a next-generation transportation means. 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. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. [10] However, the concept itself he called Magnetic Flight. This is 5–6 times the speed of sound in Earth's atmosphere at sea level.[1]. A2. Background Art. 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). For this reason, when the train travels at high speed, a problem occurs in that the upper portion of the train may severely shake or vibrate due to wind blowing from the sides of the train or due to air resistance when traveling, with the result that the possibility of the train overturning or being moved off the track is higher. The tunnel 26 is maintained in a vacuum by sucking the air in the tunnel 26 and discharging the sucked air to the outside using the suction fans 28 before the train body 2 enters the tunnel. Goddard subsequently refined the idea in a 1906 short story called "The High-Speed Bet" which was summarized and published in a Scientific American editorial in 1909 called "The Limit of Rapid Transit". 8). 7 and 10, the slide frame 17 is guided by the guide frames 18 so as to slide backwards, and thus the proximity sensors 16, which are mounted on the slide frame 17 at regular intervals, are located 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). [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. Accordingly, the train body 2, to which the field coils 11 are fixedly mounted, can be moved backwards. Esther, his wife, was granted a US patent for the vactrain in 1950, five years after his death.[4]. [2] Currently, research into magnetic levitation trains is ongoing. At the end of the line the train would be moved sideways into the end chamber of the return tube. Accordingly, the sudden braking can be achieved and, at the same time, the generation of electricity can be achieved due to the induced current that is generated by the field coils 21 and the permanent magnets 9 and 10 based on 'Fleming's right hand rule.'. [73] The manipulation lever 19, which is used to control the neutral (braking), drive and Later in April 1962, the vactrain appears in the story "Mercenary" by Mack Reynolds,[7] where he mentions Vacuum Tube Transport in passing. [61] In addition to the permanent magnets 9 and 10 and the field coils 11 mounted below the train body 2, the drive means 7 includes a plurality of proximity sensors 16, which are mounted below the train body 2 on the left and right sides of the field coils 11, and detection plates 16a, which are arranged in zigzag fashion along with the permanent magnets 9 and 10, which are arranged on the left and right sides of the lower guide rail 8 as shown in FIGS. 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. [74] In FIG.

The 1999 14 and 15). UN TED STATES PATENT FFICE. With manifold and distributor (Class 123/90.13) Hybrid valve train system. The vacuum cleaner is as a result of multiple and gradual improvements to the broom, whose use dates back to 2,300 B.C. 9 is a cut-away view showing the arrangement of permanent magnets, a field coil and proximity sensors when the magnetic levitation train according to the present invention is moved forwards by the drive means; [21] FIG. 596,575, dated January 4, … 151 Service station type (8) … [16] SpaceX built an approximately 1-mile-long (1.6 km) subscale track for its pod design competition at its headquarters in Hawthorne, California. [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. 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. [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. Disclosure of Invention Brief Description of Drawings [12] FIG. Google has many special features to help you find exactly what you're looking for. 08854978, Country of ref document: Commuter rail systems were mapped for the San Francisco and New York areas, the commuter version having longer, heavier trains, to be propelled less by air and more by gravity than the intercity version. This is distinct from the traditional hub-and-spoke model whereby rail cars enter a hub on one train and can be dispatched to their final destination pulled by another train. The accompanying drawings are provided to help understanding of various embodiments. In order to maintain the tunnel 26 in a vacuum, one or more suction fans 28 are mounted in the tunnel so as to suck air and discharge the sucked air to the outside. 3. [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.
