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 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 Accordingly, the possibility of the train body being moved off the track can be minimized. 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… A penis pump consists of a plastic tube that fits over the penis, a hand or battery-powered pump attached to the tube, and a band that fits around the base of the penis once it is erect (constriction ring).A penis pump is sometimes called a vacuum pump or a vacuum erection device. [58] Plural pairs of permanent magnets 9 and 10 are mounted on both sides of the lower guide rail 8 so as to be opposite each other. 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. 18 is a diagram showing a circuit configured by the braking-generating means of the magnetic levitation train according to the present invention. The vehicles, instead of running on a pair of tracks, would be elevated using electromagnetic force by a single track within a tube (permanent magnets in the track, with variable magnets on the vehicle), and propelled by electromagnetic forces through tunnels. [69] Meanwhile, as shown in FIGS. Several train systems using maglev have been developed over the years, with most operating over relatively short distances. The accompanying drawings are provided to help understanding of various embodiments. It seems JavaScript is either disabled or not supported by your browser. EP, Kind code of ref document: [16] SpaceX built an approximately 1-mile-long (1.6 km) subscale track for its pod design competition at its headquarters in Hawthorne, California. 11 to 13. A trip would average 4,800 km/h (3,000 mph) and subject passengers to accelerations up to 1.4 times that of gravity, requiring the use of gimballed compartments. (2) so as to brake the train body (2) and to generate electricity. The first person to patent a version of the vacuum cleaner is Daniel Hess, from West Union, Iowa, in 1860. 26 is maintained in a vacuum. The guides are mounted on the left and right sides of the upper portion of a train body. 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. 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. Accordingly, the force that is required to drive the train body 2 can be assisted by the difference between vacuum and atmospheric pressure. The New York system was to have three lines, terminating in Babylon, Paterson, Huntington, Elizabeth, White Plains, and St. The early atmospheric railways and pneumatic tube transport systems (such as the Dalkey Atmospheric Railway) relied on steam power for propulsion. [66] A braking box 22, in which a plurality of field coils 21 is mounted, is connected with a braking motor 23 via a connection member 25. The vactrain proper was invented by Robert Goddard as a freshman at Worcester Polytechnic Institute in the United States in 1904. 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. [13] They presented their idea 2013 on public stage.[14]. 1 and 3, or may be configured such that permanent magnets 14 are mounted to the lower end of the field coils 11, and such that a permanent magnet 15, having the same polarities as those of the permanent magnets 14, is laterally mounted in the lower guide rail 8, as shown in FIGS. 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. (25) are lowered into the lower guide rail (8), so that the field coils (21) are magnetized to have polarities opposite those of the permanent magnets (9, 10), and thus the braking of the train body (2) and the generation of electricity are achieved. An early maglev train was described in U.S. Patent 3,158,765, "Magnetic system of transportation", by G. R. Polgreen (25 August 1959). [4] The above-described magnetic levitation train has advantages in that it can travel fast, in that it does not generate noise, in that it generates a small amplitude vibration, and in that it is environmentally friendly because no pollutants are discharged. Evac vacuum toilets significantly reduce water consumption. Vacuum Brake Fittings and Pipes 0 Gauge Chassis kits and Accessories for scratchbuilders and kit modification. 8). 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 1999 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 … In this case, no power is supplied, the proximity sensors 16, which are mounted at regular intervals on the slide frame 17 that is located under the train body 2 and is connected with the manipulation lever 19 so as to slide, are placed on the same lines along with the field coils 11. Ed visualized an inverted cone with incoming air hitting it on an tangential angle. 6 to 10). [70] In the case where the section length of the tunnel 26 is long, partition walls 27 are mounted in the tunnel 26 for respective predetermined sections so as to be automatically raised and lowered. In this case, no electromagnetic field is generated, and thus the field coils 11 enter a nonpolar state in which no polarity exists (refer to FIG. Accordingly, when it is necessary to brake the train body 2, the braking-generating means 20 enables the braking to be achieved by the permanent magnets 9 and 10 and the magnetic force while the braking box 22, in which the field coils 21 are mounted, is lowered into the lower guide rail 8. 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. Industrial Applicability. A penis pump is one of a few treatment options for the inability to get or maintain an erection sufficient for sex (erectile dysfunction). [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 are spaced apart from the guides 5 due to magnetic force, thereby safely guiding the left and right upper portions of the train body 2. Construction would make use of lasers to ensure alignment and use tungsten probes to melt through igneous rock formations. [citation needed], On November 18, 1991, Gerard K. O'Neill filed a patent application for a vactrain system. 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. [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. which is mounted to the magnetic levitation train according to the present invention; [24] FIG. The drive unit is mounted under the train body and is provided with a drive means and a lower guide rail. The permanent magnets are mounted on the left and right sides of the lower guide rail so as to be opposite each other. Furthermore, in the above-described existing magnetic levitation train, the gap between the rails and the train is wide. [3] 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". This is 5–6 times the speed of sound in Earth's atmosphere at sea level.[1]. In order to commercialize such magnetic levitation trains, a large number of nations are devoted to their research and development. [78] Here, since the technology for controlling current by operating the proximity sensors. [55] To this end, as shown in FIGS. 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. Push-pull operation can be achieved in the manner shown in FIG. [2], The vactrain proper was invented by Robert Goddard as a freshman at Worcester Polytechnic Institute in the United States in 1904. 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. 16 is well known, detailed descriptions thereof are omitted. 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). The railway would have both an inner evacuated tube and an outer tunnel. A2. Here is how vacuum cleaners came to be: 1860: Daniel Hess of West Union, Iowa, invented a carpet sweeper, a predecessor of vacuum cleaner, which had a rotating brush and bellows which generated suction but it was never mass produced. The vacuum cleaner is as a result of multiple and gradual improvements to the broom, whose use dates back to 2,300 B.C. 151 Service station type (8) … @article{osti_644372, title = {Compact cyclone filter train for radiological and hazardous environments}, author = {Bench, T R}, abstractNote = {A compact cyclone filter train is disclosed for the removal of hazardous and radiological particles from a gaseous fluid medium. [11] To obtain such speeds, the vehicle would accelerate for the first half of the trip, and then decelerate for the second half of the trip. 12 is a sectional view illustrating the operation of the braking-generating means, Enormous construction costs (estimated as high as US$1 trillion) were the primary reason why Salter's proposal was never built. 08854978, Country of ref document: [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. 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. Thanks to these advantages, the magnetic levitation train is expected to be used in urban areas as a next-generation transportation means. The present invention may be modified in various ways within a range that does not depart from the technical spirit of the present invention. Then there are many systems that brave the challenges of 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. 1 is a front sectional view showing the construction of a magnetic levitation train according to the present invention; [13] FIG. Terraspan's giant, 4,000 mph (6,437 km/h) vacuum tube train, which also doubles as a superconducting power line. 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".
