Abstract: An adaptor for an older Corvette drive train provides a structure for coupling the drive shaft extending from a front-mounted transmission to the differential of a C5 or C6 Corvette rear suspension in which the rear mounted transmission has been removed. A housing holds a stub shaft for rotation on front (outside) and rear (inside) bearings. The shaft has a coupling yoke mounted to its front end and engages the differential gearing at its other (rear) end. The housing mounts to the differential at the five mounting points of the removed transmission. A bracket which attaches to frame mounts can be mounted to either the top or bottom front (outside) face of the housing, depending upon the suspension-to-frame geometry. A circular flange on the shaft positions and holds the inside bearing and a rearward extending boss on the yoke positions and holds the outside bearing.

Abstract: A sliding and rotating hinge module for supporting a display screen or the like, includes a bracket, a slider and a support member. The slider is capable of sliding movement relative to the bracket and the support member is capable of pivotal movement relative to the slider. A drum is rotationally supported by the bracket. A constant force spring is attached to the drum at one end and to the slider at the other end. The constant force spring is biased to wrap around the drum, the constant force spring unwrapping from the drum as the slider moves toward the retracted position. The constant force spring biases the slider toward the extended position. A damping mechanism damps the rotational motion of the drum relative to the bracket for smooth, non-abrupt movement of the slider.
