A hypodermic syringe comprises a cylindrical piston barrel, a piston plunger slidable in and extending out one end of the piston barrel, a rubber-like piston attached to one end of the piston plunger, a needle extending from the other end of the piston barrel, and a spring-loaded needle cover in the form of a cover tube slidable over the piston barrel. The cover tube includes a locking mechanism for locking the cover tube in an extended position over the needle or in a retracted position exposing the needle. The locking mechanism comprises an axial slot or keyway provided on the cover tube and having transverse projections at each end, a pin on the piston barrel adjacent to the needle end extending radially outwardly into the slot of the cover tube, and a spring positioned between the distal ends of the piston barrel and the cover tube. In the retracted position of the cover tube, the spring located inside the cover tube is compressed. When an injection is given, the cover tube is automatically unlocked and the compressed spring expands, pushing the cover tube over the needle. Once over the needle, the cover tube is locked in place. In operation the slot rides against the pin and guides the movement of the cover tube.

A hypodermic syringe comprises a barrel, a plunger slidably received in the barrel, a drive shaft slidable in the barrel, and a connector for drivably connecting the drive shaft to the plunger. The connector has a plunger end including a first pair of resilient fingers insertable into the plunger, a drive shaft end having second pair of fingers insertable into the drive shaft, and an intermediate portion intermediate the plunger and drive shaft ends. The first pair of fingers has projections which engage apertures in the plunger. The second pair of fingers engages an annular rib in the drive shaft. When the drive shaft is fully inserted into the barrel to bottom the plunger, the drive shaft slides over the first pair of fingers, causing the fingers to retract and the projections to disengage from the apertures in the plunger. The connector remains engaged with the drive shaft, and separates from the plunger the drive shaft is withdrawn from the barrel, thereby preventing further use of the syringe.

A tower-type speaker cabinet assembly for plural speakers of a high fidelity audio system, including a vertically elongated tower cabinet having a pair of front wall segments adjacent the uppermost and lowermost ends of the tower speaker cabinet and an intermediate forwardly opening cavity extending between the upper and lower front wall segments, a pair of vertically spaced large subwoofer speakers in the respective upper and lower front wall segments with associated inner cabinets forming sound boxes therefor, and a swivelled movable center subcabinet spanning the vertical distance between said front wall segments, having a woofer, a mid-bass speaker and a pair of tweeters carried by a front wall portion of the center subcabinet in vertical alignment. The subcabinet has a range of swivel movement horizontally through predetermined angles about a vertical axis located a short distance rearwardly from the front wall of the swivelled subcabinet. Shock absorber strips are provided between the inner cabinets and the outer cabinet for minimizing vibration transfer therebetween.

An adaptor for playing a magnetic tape cassette in a tape player for 8-track endless tape cartridges, including an adaptor housing whose horizontal width and depth dimensions and peripheral shape adjacent the bottom thereof are substantially the same as that of the endless tape cartridge to fit in the cartridge-receiving cavity of the tape player. The housing is shaped to form an upwardly opening well for receiving the magnetic tape cassette, and has a tape driving capstan for driving the cassette tape, and a capstan drive train for selectively driving the capstan from the tape drive of the cartridge player, including a pivoted power takeoff lever and pulley to couple and decouple with the cartridge tape drive, and a pivoted function control lever having an end portion movable relative to the takeoff lever to position the latter at non-driven and release positions. The function lever is releasably restrained at Play and Stop positions, and an automatic stop tape sensor lever having a sensor formation engaging the cassette tape is provided to shift the function control lever to Stop position when the tape is fully unwound from the supply reel of the cassette.

A speaker assembly for installation in automobiles as in automobile rear decks and like installations in automobiles, including a main speaker section having a speaker basket frame provided with mounting ears for receiving mounting studs to fix the speaker basket frame against the underside of a deck in the automobile. The main speaker section includes a woofer speaker unit and a bridge member supported from the basket frame carrying a tweeter speaker unit. A grille panel of unitary plastic material has a set, usually four, of spaced preformed sockets to receive upper end portions of threaded mounting studs to be screwed by hand pressure, and then with pliers or the like into the holes, after which a flat spring nut is screwed down on each threaded stud, or one-piece shouldered threaded mounting studs may be used without the spring nut. The studs and grille are positioned on the deck with the studs extending down through the mounting holes in the automobile rear deck, the main speaker section is positioned onto the studs below the deck, and speed nuts are screwed onto the studs.

A multirange thin speaker assembly for installation in automobile doors and like constricted space installations in compact automobiles and the like with the front of the assembly facing toward the automobile interior, including a main speaker section having a speaker basket frame provided with mounting ears for receiving front mounting screws to fix the speaker basket frame against an interior wall portion of the automobile door. The main speaker section includes a woofer speaker unit and a bridge member supported from the basket frame carrying a tweeter speaker unit. A front grille panel of unitary plastic material has a pair of transversely spaced arcuate rear snap ring segments forming an interrupted annular ring projecting rearwardly from the panel to interfit in an anchor ring member carried by the basket frame, each having radially outwardly projecting bead formations to snap behind retaining shoulders of the anchor ring to fasten the grille panel to the anchor ring.
