Abstract: Disclosed is a pinch roller for use in continuous magnetic tape cartridges. In one preferred embodiment, the pinch roller has an inner and out cylindrically shaped wall interconnected by a plurality of flexible U-shaped webs. Each wall has a flange extending radially from the mid-point of the axial length of the roller. These flanges are interconnected by U-shaped webs. The U-shaped webs extend above and below the mid-point in alternate and adjoining relationship so that the outer wall of the roller can move to an eccentric position with respect to the inner wall and/or permit the outer wall to align itself with the capstan should the cartridge be disposed with the principal axis of the roller at an angle to the capstan.

Abstract: A plastic violin is provided with means for compensating for change of tension in the violin strings due to dimensional instability of the plastic caused by variations in temperature or pressure. The plastic violin comprises an elongated bar below the finger board and is bonded thereto. An elongated stabilizing bar is placed in the hollow portion of the violin body and has a proximal end which abuts an upright portion or identation in the reinforcing bar and a distal end which is received by a threaded compensating screw which is manipuable to bias the proximal end of the stabilizing bar against the surface of the indented upright portion of the reinforcing bar.
