Abstract: ABSTRACT OF THE DISCLOSURE           A toy vehicle is provided for use in a toy vehicle game including an endless track defining at least two parallely extending vehicle lanes in which two or more toy vehicles are adapted to be operated.  The toy vehicles each include a reversible rotary drive motor and a trans-mission operatively engaged between the motor and two drive wheels for rotating one or the other of the drive wheels, in response to the direction of rotation of the drive motor, thereby biasing the car against one or the other of the side walls of the track to guide the vehicle along its path of travel in one or the other of the lanes.  The track includes electrical contact strips which supply power to the drive motor of the vehicles through current collectors mounted thereon.  A control system permits the operators to separately and independently control current to the contact strips and also to selectively reverse the polarity of the current so that the operators can vary the speed of their associated vehicles and cause the vehicles to move from one lane to the other.  The toy vehicle includes a swing gear responsive to the direction of rotation of the vehicle's drive motor for driving one or the other of the rear wheels of the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention is directed generally to connectors and more particularly to an assembly for use in a fiber optic cable connector which aligns and spaces the terminal ends of a pair of cables.  Prior art connectors for this purpose have not been completely satisfactory, particularly where frequent connects and disconnects must be made under adverse environmental conditions, or where multiple fiber optic circuits must be connected in a single connector be-cause of the difficulty of maintaining an accurate consistent alignment between the ends of coupled cable segments under such conditions.  The invention provides an assembly for aligning and spacing the terminal ends of a pair of fiber optic cables to achieve efficient light transfer between the cables.  The assembly includes a first terminal pin having a bore for receiving the terminal end of one of the cables and having an external shoulder portion, a second terminal pin having a bore for receiving the terminal end of the other cable and having an external shoulder  portion, and resilient sleeve means tightly received over the ter-minal pins for aligning the terminal ends in facing relation and for contacting the external shoulders to effect a pre-determined spacing to provide an efficient light transfer between the fiber optic cables.  In a preferred form, each terminal pin includes an insert member which has a concen-tric channel for receiving and aligning the fiber optic cables concentric with the outer dimension of the terminal pins.
