Abstract: A bus bar mount on which a current collecting equipment rides comprises an electrically insulating elongate body having a longitudinally extending groove and a longitudinally extending lid hinged to the body proper, a current carrying naked cable set in the groove, and latching means for providing latching engagement of the lid with the body proper to sealingly close the groove when the lid is pressed against the body proper. The current collecting equipment comprises a current collecting shoe, a rod connected to a body of the equipment to forcedly open the lid allowing the shoe to be brought into sliding contact with the naked cable when moved in a direction along the bus bar mount, and a press-roller unit connected to the body of the equipment at the position opposite to the rod with respect to the shoe to press the open lid against the body proper of the mount for providing the latching engagement of the lid with the body proper when moved in the one direction.

Abstract: A cable holder device for holding current-carrying cables spaced apart but biased to maintain contact with two current-collecting shoes. The shoes are mounted on a self-propelled cable car having an electric drive motor connected to the shoes and driven apparatus constructed as a driven pulley for suspending the cable car on a suspension cable from which the cable car is suspended and on which it travels. The holder maintains positive contact between the current-carrying shoes and the current-carrying cables regardless of the swaying of the cables and the cable car.

Abstract: The disclosure relates to a dual-mode bus which is operable on a guideway under automatic control and also operable on ordinary surface streets or highways under the control by a bus driver. The dual-mode bus comprises a rear axle having at both ends thereof traction wheels, a frame supported on the axle and a current collector. A floating support is connected between a differential gear housing of the rear axle and the frame and has two spaced portions, first one of which is disposed nearer to the axle than second one of the two spaced portions thereof. An arm having two spaced portions is provided, first one and second one of which are connected to the first and second portions of the floating support, respectively. The arm carries the current collector at a third portion spaced on the same side as the first portion of the arm, from the second portion of the arm. The third portion is spaced, further than the first portion of said arm, from the second portion of the arm.

Abstract: Electric power is provided to the motor of a self-propelled carriage of an aerial ropeway through two cables by which the carriage is supported.

Abstract: A vehicle adapted to travel over roads under the control of a driver operating a vehicle wheel control system or to be automatically steered along a guideway has a pair of guideway contacting wheels that control the steering when extended to a predetermined portion to contact the guideway and when retracted permit steering by the driver. A hydraulic control cylinder has oppositely disposed pistons connected by axially aligned piston rods to the respective guideway contacting wheels and movable to extend and contact these wheels. A mechanical linkage system is disposed, respectively, between one piston rod and the vehicle wheel control system.

Abstract: A first link member branched into two straight arms at a fixed angle is pivotally supported by the vehicle body at the branching point, and the free end of the first arm is linked with a connecting rod which in turn is connected to a steering arm for a road wheel while the free end of the second arm is pivoted to an end of a straight second link member which is equal to the second arm in length, the other end of which second link member is pivoted to a middle portion of a rod supporting at the ends thereof a pair of guide wheels. The rod is provided with means to move the rod relatively to the vehicle body thereby to retract the guide wheels and rotate the second link member until it forms no angle between the second arm.
