Abstract

1360834 Electric railways JAPANESE NATIONAL RAILWAYS 7 July 1971 [7 July 1970 25 Sept 1970 (2)] 31925/71 Heading B7L [Also in Division H2] A linear propulsion system for a movable body comprises a plurality of rectangular coils 1-1 … 1-6, Fig. 1, vertically arranged along a horizontal path and a permanent or electromagnet 2 carried by the body for generating a magnetic field directed transversely of the coils so that when the coils are D.C. energized the horizontal portions thereof produce a lifting force on the body and certain of the vertical portions produce a driving force along the path, switching means being provided for energizing selected coils in the region of the body as it moves along the path. The magnet core may be C-shaped so as to utilize only one horizontal portion of each coil to produce lift or two opposing C-shaped cores may be located on opposite sides of the coils so that both horizontal portions thereof may be utilized, Fig. 5 (not shown). In the embodiment shown in Fig. 6(b), two lines of interconnected coils 11, 111 are mounted in parallel on a track 14a and co-operate with an E-shaped electromagnet 2a carried by the body 6. The coils are connected to lines of conductive segments 9, 10, each coil having a segment located opposite to it, and current is supplied to the segments by roller contacts 11, 12 carried by the electromagnet and which connect the segments in turn to bus-bars 8, 9 as the body moves. The contacts are staggered relative to each other in the longitudinal direction so that a selected span of coils is energized at a given time, and to vary the position of the span with respect to the electromagnet to change from a driving condition to a coasting or braking condition, the roller contacts are mounted on motor-driven threaded rods 111c, Fig. 6c, so that they can be displaced in the direction of movement of the body. Guide rails 15 for the electromagnet are provided at the sides of the track on which the electromagnet rests when deenergized. As shown, the bus-bars and contactsegments are mounted centrally of the track but they can be located externally of the electromagnet adjacent the rails 15, Fig. 6d (not shown). Also, the coils may be arranged in overlapping relation instead of being end-toend, Fig. 8 (not shown). In a further embodiment, Figs. 10 and 11 (not shown), the coils are connected to the bus-bars through thyristors mounted on the track and turned on and off sequentially by transducers responsive to signals, e.g. light signals, emitted by generators carried by the electromagnet in place of the roller contacts 11, 12, the generators being adjustably mounted similarly to the roller contacts.
