Abstract: An elongated housing in the general shape of an inverted “U” having a lengthwise slot in a lower portion which includes six inner elongated conductor strips. Disposed within the housing and extending through the lower slot is a trolley with four sets of three conductive contact brushes each in linear alignment, with each set of three conductive contact brushes engaging one of four input power conductor strips. The trolley includes two additional brushes each in contact with a respective control conductor strip in the housing. The trolley is coupled to and controls the operation of a mobile machine such as used in automatic storage/retrieval systems.

Abstract: A highway-vehicle system for high speed travel which comprises a below-ground structure defining a cavity and a narrow slot extending upwardly therefrom to the roadway surface. Each vehicle in the system is equipped with a projecting member which, in its folded configuration, can be lowered into the slot. The projecting member includes a pair of stabilization wheels and a pair of hydraulically or pneumatically-actuated brake shoes. Once the projecting member has been lowered into the cavity, the wheels automatically unfold, so that they assume horizontal positions and press against opposing sidewalls of the cavity. With the wheels so deployed, the vehicle can be safely driven during high speed cornering and under windy conditions. The wheels can also be used to automatically steer each vehicle. In addition, the wheels are used to conduct electricity in the cavity sidewalls as part of the power takeoff for an electric vehicle.

Abstract: A buried power supply system for an electric vehicle (17) equipped with collector shoes (16, 22), the system comprising a succession of conductive segments (5A, 5B, 5C) that are electrically isolated from one another, and that form a conductive track for the shoes on a road surface. Each segment is provided with individual switching means (11) of the static type, which means are received under the segment in a trough along which a common power supply link (14) and a common return link (13) run. The switching means provide electrical continuity between the segment to which they are assigned and the power return link so long as a connection control signal for connecting a segment to the power supply link is not received from a vehicle either directly by the segment in question (5C) or by either of the immediately adjacent segments (5B, 5D). The vehicles include means for transmitting a connection control signal to a segment of track.

Abstract: An extruded plastic housing of indefinite length contains an electrical conductor bar in a slot extending lengthwise of the housing. The bar is retained in the slot by a pair of ribs integral with the side walls of the slot and extending lengthwise thereof and projecting toward each other. The width of the bar is greater than the space between the ribs, but the housing is so formed that in assembling it and the bar the distance between the ribs can be increased temporarily by pressure of the bar against them to permit it to be moved rearwardly past the ribs, whereby the bar can be inserted from the front or outer side of the slot, thus permitting the use of a single conductor bar regardless of the number of housing units that may be disposed end to end to form the housing.
