[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. Accordingly, the train body 2, to which the field coils 11 are fixedly mounted, can be moved backwards. 596,575, dated January 4, … Construction would make use of lasers to ensure alignment and use tungsten probes to melt through igneous rock formations. 16 is well known, detailed descriptions thereof are omitted. Push-pull operation can be achieved in the manner shown in FIG. 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. 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. Accordingly, when the train body 2 travels, accelerating force can be maximized by minimizing air resistance. [2] Currently, research into magnetic levitation trains is ongoing. 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. 2002-01-03 Priority to US34576402P priority Critical 2002-12-16 Priority to US10/320,729 priority patent/US6883201B2/en 2002-12-16 Application filed by iRobot Corp filed Critical iRobot Corp 2003-01-16 Assigned to IROBOT CORPORATION reassignment IROBOT CORPORATION ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). Using Vacuum as an Atmosphere. 6, the speed of train body is controlled in proportion to the degree of rotation of the manipulation lever 16. 7 is a cut-away plan view showing the arrangement of permanent magnets, field coils and proximity sensors when the magnetic levitation train according to the present invention is moved backwards by the drive means; [19] FIG. However, in the above-described existing magnetic levitation train, field coils and permanent magnets are mounted in a ratio of 1 : 1, so that a problem occurs in that a great amount of energy is consumed. 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". [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. [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. Then there are many systems that brave the challenges of 2 and 4. 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. Between the years 1790 and 1880 the U.S. Patent Office required both documentation and a three-dimensional working model to demonstrate each new invention submitted for a patent… [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. 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 This figure presents the amount of water (m 3) saved with Evac vacuum toilets compared to traditional gravity toilets since the … The drive unit is mounted under the train body and is provided with a drive means and a lower guide rail. AUTOMATIC VALVE FOR TRACK-SANDERS. 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 [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. He called underground Very High Speed Transportation (tube shuttles) his nation's "logical next step". [8] The present invention provides a magnetic levitation train, which can achieve excellent stability, can travel at high speed, and can minimize energy costs. A penis pump is one of a few treatment options for the inability to get or maintain an erection sufficient for sex (erectile dysfunction). [12], ET3 claim to have achieved some work that resulted in a patent on "evacuated tube transport technology" which was granted in 2009. slightly ahead of the field coils 11. Even more » 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. 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. But today, one of the main proponents is American engineer Daryl Oster, who holds the patent for what he calls Evacuated Tube Transport. 15 is a transverse sectional view schematically showing the case where the magnetic levitation train according to the present invention moves through a tunnel; [27] FIG. Thanks to these advantages, the magnetic levitation train is expected to be used in urban areas as a next-generation transportation means. Vacuum Cleaner Timeline We don’t have vacuum cleaners too long now - a hundred and some years and today they are part of almost every household. Google has many special features to help you find exactly what you're looking for. The plans were never taken to the next stage. [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. In the case where the train body travels at high speed, the proximity sensors 16 encounters with the detection plates 16a before the field coils 11 reach the locations of the permanent magnets 9 and 10, so that the polarities of the field coils 11 are changed in advance before the field coils 11 reach the locations of the permanent magnets 9 and 10, and thus a large amount of force can be imparted to the train body when the train body is moving. [5] The magnetic levitation train according to claim 1, wherein: the upper guide rails (3) and the drive unit (4), through which the train (2) passes, are mounted in a tunnel (26), partition walls (27) are mounted in the tunnel (26) for respective predetermined sections so as to be automatically opened and closed by an opening detection sensor (30) and a closing detection sensor (31), which are mounted in respective front and rear ends of the train body (2), and detection parts (32, 33), which are mounted in the tunnel (26) so as to be detected by the opening and closing detection sensors (30, 31); and one or more suction fans (28) are mounted so as to discharge air in the tunnel, PROPULSION OF ELECTRICALLY-PROPELLED VEHICLES; SUPPLYING ELECTRIC POWER FOR AUXILIARY EQUIPMENT OF ELECTRICALLY-PROPELLED VEHICLES; ELECTRODYNAMIC BRAKE SYSTEMS FOR VEHICLES IN GENERAL; MAGNETIC SUSPENSION OR LEVITATION FOR VEHICLES; MONITORING OPERATING VARIABLES OF ELECTRICALLY-PROPELLED VEHICLES; ELECTRIC SAFETY DEVICES FOR ELECTRICALLY-PROPELLED VEHICLES, Electric propulsion for monorail vehicles, suspension vehicles or rack railways; Magnetic suspension or levitation for vehicles, Magnetic suspension or levitation for vehicles, Self-regulating magnetic levitation system, Earth system of magnetic levitation train, Transportation system of a floated-carrier type, Superconducting electromagnet for levitation and propulsion of a maglev vehicle, Short block linear synchronous motors and switching mechanisms, Transportation system, rail module and the method for making delivery vehicle commutate, Levitation system using permanent magnets for use with trains and the like type of right-of-way vehicles, Transport system powered by short block linear synchronous motors, Magnetic levitation train provided with an eddy-current brake, A kind of planet gear type barrier-surpassing robot, Wormgear shaped driving part, elevator using wormgear shaped driving part and elevating system, Vehicle guidance and switching via magnetic forces, Magnetic levitation railway system with suspension rail and permanent magnets, Trolley for rail tracks that are branched by means of switch points, Short block linear synchronous motor and changement, Wheel type barrier-crossing wall-climbing robot, Linear synchronous motor power control system and methods, Ep: the epo has been informed by wipo that ep was designated in this application, Ep: pct application non-entry in european phase. 12 is a sectional view illustrating the operation of the braking-generating means, 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. 08854978, Country of ref document: 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. The upper guide rails are mounted to the left and right portions of the train body opposite the guides. [5] However, the magnetic levitation trains which are known at present are problematic in that they cannot travel fast and have low traveling stability. [68] The braking motor 23 is rotated in the forward and backward directions by the manipulation of the braking motor switch 19a, which is mounted on the manipulation lever 19 as shown in FIG. He called the company he wanted to form VSE International, for velocity, silence, and efficiency. 1 to 18. Patent trolls make money by doing (very) lose pattern matching between what you do and the patent they hold, and then they demand an amount that they expect … 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. Technical Solution. Accordingly, the train body 2 can selectively travel forwards or backwards. At cruise depth, the space between would have enough water to float the vacuum tube, softening the ride. 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. 11 to 13. 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 force attributable to the difference between the atmospheric pressure and the vacuum can be imparted, and thus the train body 2 can travel at higher speed. [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. 14 is a longitudinal sectional view schematically showing the case where the magnetic levitation train according to the present invention moves through a tunnel; [26] FIG. How long would it take? Maglev being poorly developed at the time, he proposed steel wheels. During the 1970s, a leading vactrain advocate, Robert M. Salter of RAND, published a series of elaborate engineering articles. The tunnel would be buried to a depth of several hundred feet in solid rock formations. The magnetic levitation train includes guides, upper guide rails, a drive unit, plural pairs of permanent magnets, field coils, and a guide means. [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. Gravity would further accelerate the departing train down to cruise level. [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 When the train body 2 passes through the section of the front and rear partition walls 27, the closing detection sensor 31, which is mounted in the rear portion of the train body 2, detects the detection parts 33, and thus the partition walls 27 are automatically opened. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. 1 to 4, guides 5, which are located on the left and right sides of the upper portion of the train body 2 and are made of permanent magnets, are mounted in the longitudinal direction of the train body 2. Rising from cruise level, the arriving train would decelerate by compressing the rarefied air ahead of it, which would be vented. [63] The manipulation lever 19 functions to selectively control the forward and backward movements of the train body 2. An early maglev train was described in U.S. Patent 3,158,765, "Magnetic system of transportation", by G. R. Polgreen (25 August 1959).
