vacuum train patent

[2] The magnetic levitation train according to claim 1, wherein the guide means (12) is a bearing (13) that is mounted to the lower end of the field coils (11) so as to be guided into the lower guide rail (8). This figure presents the amount of water (m 3) saved with Evac vacuum toilets compared to traditional gravity toilets since the … 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).

[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 plans were never taken to the next stage. 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". 18. [63] The manipulation lever 19 functions to selectively control the forward and backward movements of the train body 2. [citation needed], On November 18, 1991, Gerard K. O'Neill filed a patent application for a vactrain system. 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. Pumps at the stations would make up for losses due to friction or air escaping around the edges of the train, the train itself requiring no motor. 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 In this case, each of the field coils 11 is magnetized to have the same polarity as that 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 opposite polarities to those of permanent magnets that are located ahead of a corresponding field coil, and thus an attractive force acts on each other. [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. A2. 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. Accordingly, the train body 2 can be normally braked or can be moved forwards or backwards (refer to FIGS. [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. In 1797, Levi Dickenson perfected the earlier broom after noticing his wife’s did not sweep and bristles were falling off. [12], ET3 claim to have achieved some work that resulted in a patent on "evacuated tube transport technology" which was granted in 2009. 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. The tunnel would be buried to a depth of several hundred feet in solid rock formations. 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. [54] The magnetic levitation train 1 according to the present invention includes upper guide rails 3, which are configured to safely guide the upper portion of a train body 2 by levitating the upper portion of the train body 2 so as to space it apart from the upper guide rails 3 by a predetermined distance using a magnetic repulsive force and preventing the upper portion of the train body 2 from being moved off the upper guide rails 3, and a drive unit 4, which is mounted under the train body 2 and is configured to selectively drive the forward or backward movement of the train body 2. 16 is well known, detailed descriptions thereof are omitted. The vacuum cleaner is as a result of multiple and gradual improvements to the broom, whose use dates back to 2,300 B.C. 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. [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. 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. of torque when traveling but also reducing energy costs. In addition, the magnetic levitation train is designed to travel along a tunnel, so that it can always travel regardless of weather or climate. [53] That is, it is apparent that the scope of the present invention is not limited by the drawings themselves, which are accompanied to illustrate embodiments, and that simple modifications or substitutions of components are included in the scope of the present invention. The magnetic levitation train includes guides, upper guide rails, a drive unit, plural pairs of permanent magnets, field coils, and a guide means. [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. 1 to 18. An early maglev train was described in U.S. Patent 3,158,765, "Magnetic system of transportation", by G. R. Polgreen (25 August 1959). He made some brooms from sorghum and even sold them across New England such that by 1850 they were known as broomcorn. [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. An air pump 20, labelled "PUMP", with flow ports 64, pressurizes the pressure vessel 21 while drawing a vacuum in the vacuum vessel 22. This air movement knocked dirt off the filter cone and sent it to the vacuum's pan below. [82] The magnetic levitation train according to the present invention is configured to use 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. 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. [3] Such a magnetic levitation train is levitated by magnetic force so as to travel over rails. 1 is a front sectional view showing the construction of a magnetic levitation train according to the present invention; [13] FIG.
