Abstract: A tape handling device for the handling and storage of an endless flexible tape is described. The device may be used in conjunction with audio recorders, equipment controllers, data processors, or other systems requiring signal storage on tape. The device includes a storage bin having tape entrance and exit ports and a central storage area in which the majority of the tape is stored at any time in a series of serpentine folds. A tape drive mechanism drives the tape out of and into the bin and past a transducer head or heads. A vacuum plenum is connected to the storage bin for drawing air into the bin through the ports and out of the bin through the plenum connection, the air flow acting to draw the tape into the bin through the entrance port.

Abstract: An improved stopper apparatus for bottles, such as wine bottles, which prevents contamination of the contents therein. The improved stopper apparatus comprises a stopper plug, a bladder attached thereto, a venting valve for venting gas within the bottle, a pump for inflating the bladder and a reservoir valve and inert gas reservoir. The bladder is inserted into the bottle and the stopper plug secured within the neck thereof. The bladder is filled within the bottle forcing the gas therein to escape through the venting valve. The stopper apparatus is adapted to enable a small quantity of heavy inert gas to be deposited into the bottle from the inner gas reservoir prior to filling the bladder, whereby to form a protective layer of inert gas over the surface of the bottle's contents.
