Title: Low profile magnetic tape drive with vacuum actuated auto-threading
Inventor: PETER JACK
IPC: G11B15/66
Filed: 1980-07-04
Abstract: Supply (22) and take-up (34) reels are mounted above a horizontal base (28) for selective powered rotation about respective vertical axes. Vertical guide surfaces (74, 74a, _ 74b) and a cover panel define an air tight continuous flowpath (76) extending between the peripheries of the reels past a read/write head (58). A blower (78) mounted in a hood structure (84) beneath the base sucks air through the flowpath and through a perforated center spool (48) of the take-up reel. A river of air thus pulls and guides the free end portion of the magnetic tape from the supply reel to the take-up reel as the supply reel is rotated by a drive motor to unwind the tape therefrom. The supply hub (40) is adapted to automatically center the supply reel thereon. The supply hub further includes a plurality of annularly spaced reel engaging pawls mounted in, and normally ratracted into the hub, and an over-center actuating means for selectively extending the pawls through differential rotation of a pair of separate rotors included in the hub.

Abstract: A figure toy (10) which includes a unique actuating mechanism (60) which cooperates with a novel shoulder assembly (22) which allows the toy (10) to emulate a shrug or a wave and to perform other functions of the same sort in a very realistic manner. The shoulder assembly (22) includes a member which pivots about one end (52) when it receives pressure from the actuating mechanism (60). The other end of the assembly (22) is attached to an arm (16). Thus, the motion of the shoulder assembly (22) moves the shoulder upwardly and inwardly simulating very closely the raising of the human shoulder such as occurs during a shrug or a wave. The arrangement allows one or the other or both of the shoulders together to be raised.
