A windshield repair apparatus includes a bridge for holding an injector adjacent to a break area of a windshield. The bridge includes a suction cup for mounting the bridge to the windshield. The bridge includes a pivotally mounted arm which allows for pivotal movement of the injector away from the break area, and a registration system which allows for accurate replacement of the injector over the break area following pivotal movement back toward the break area. A ball plunger and detent mounting arrangement between the pivotally mounted arm and a remainder of the bridge allows for registration. The suction cup includes a vacuum pump for withdrawing air from beneath the suction cup. The injector includes a clip securing a stopper to a body of the injector. The stopper includes a peripheral lip seal at a first end of the stopper which is received by the body.

A loading assembly that permits a lateral force to be applied parallel to an axis of a vehicle spindle includes a support frame and a wheel adapter housing mounted to the vehicle spindle. A loading member is pivotally joined to the support frame at a position spaced apart from the wheel adapter housing on the axis of the spindle. A plurality of spaced apart struts connects the loading member to the wheel adapter housing. An actuator applies a selected force to the loading member, which is transferred as a lateral force to the vehicle spindle. In a first embodiment, an adjustable coupling is provided between the actuator and the loading member to emulate a rolling radius of a tire assembly mounted to the vehicle spindle. In a second embodiment, a second loading member is operably connected to the first-mentioned loading member. A second actuator applies a force to the second loading member to apply a selected moment to the vehicle spindle.

Anomalously large photoresponse to radiation of energies between about 2. 8 eV and about 3. 8 eV has been observed in certain gallium phosphide photodetectors having an "as-grown" surface. This photoresponse is believed to be due to the low density of recombination centers in the as-grown surface.

A windshield repair apparatus is provided which includes a bridge having a base member including an injection holder and a pivot support member pivotally connected to the base member. A suction cup is disposed for connection with the pivot support member for mounting the bridge to the windshield. A yoke extends upward from the suction cup to pivotally connect the suction cup to the pivot support member of the bridge. The yoke includes at least two side members which are adapted to receive the pivot support member of the bridge therebetween such that the bridge is permitted to pivot vertically about a pivot axis toward and away from the windshield and wherein the side members of the yoke prevent the pivot support member from rotating in a horizontal orientation substantially parallel to the windshield. The bridge includes a registration system engageable with the pivotally mounted base of the bridge for retaining the base member of the bridge in the original position and for selectively permitting rotation of the base member of the bridge from the original position to a rotated position upon the manual retraction of the registration system by the user to release the base member from connection with the pivot support member. The registration system includes a locking pin disposed within a base member of the bridge and biased for engagement with a corresponding locking cavity formed in the pivot support member.

A straightening press of the type wherein a workpiece is supported for deflection in a given direction by an anvil engageable with the workpiece. A reference spring is supported for deflection with the reference spring supports being serially interconnected with the anvil. In a preferred embodiment, a floating bridge carries the anvil and reference spring supports. Deflecting force applied to the reference spring, as by a ram, is transmitted to the workpiece via the floating bridge. A change in the differential displacement of the ram and floating bridge is detected to determine the onset of plastic deformation of the workpiece.

The apparatus converts reciprocating motion of a rowing type exercise into single direction rotational motion of a shaft in a predetermined direction. A reciprocable arm of a rowing type exercise is pivotally mounted to a frame. A shaft, set for rotation in the frame has first and second one way clutches. First and second racks are mounted with respect to the reciprocable arm and engage one or the other of the one way clutches for driving the shaft in a predetermined direction of rotation as the arms are reciprocated. One or the other clutches freewheels against its respective rack when one of the racks is moved in to drive the shaft and thereby retains the driving rack in engagement with its respective one way clutch.

A safety shield construction for use with wood turning lathes and similar machines which provide a "see through" shield mounted in a perimeter frame which is movable between closed and open positions. Inertia actuated locks prevent the shield from being knocked open by a sharp blow from a broken workpiece, but permit the shield to be moved to the open position manually. The inertia locks are fail safe and are moved to locked position whenever the shield is moved to closed position. Thus if the inertia locks become inoperative they will be in locked position for safety. The shield construction includes rigid supports attached to the lathe bed which utilize a rigid torque tube that attaches on brackets which permit adjustment of the shield along the length of the lathe to not only serve as a shield for long workpieces, but also as a shield during face plate operation. The torque tube is not substantially longer than the length of the frame of the shield, and permits longitudinal adjustment while maintaining rigidity and strength.
