Abstract: A air gas detection pack is provided. The air gas detection pack has a card receiving pocket which slidably receives a gas detection card, the gas detection card having a plurality of chemically reactive materials retained therein and exposed to outside air through a plurality of aligned air permeable apertures formed in the front and rear wall of the substance detection pack. The combined gas detection card and gas detection pack indicates the concentrations of gases in the air. The air permeable apertures in conjunction with the reactive materials of the substance detection card are covered with a filtering media to protect the reactive material from dirt and dust contamination.

Abstract: The invention is a sharpener for a knife of a food slicer. The sharpener includes a base assembly and a sharpener assembly. The base assembly includes a lever mounted thereto on a pivot; the lever carrying a cam member which extends therefrom. The sharpener assembly includes a housing and a longitudinal cavity, a sharpening wheel mounted for rotation on an axle which reciprocates lengthwise in the cavity, a compression spring positioned in the cavity at the base of the axle, and an actuator which reciprocates in the cavity portion on the side of the spring opposite the axle. Upon moving the lever about its pivot, the cam contacts the actuator and moves the actuator in the direction of the axle and compresses the spring. The spring moves the plunger lengthwise within the cavity and urges the sharpening wheel against the knife.

Abstract: An apparatus (10) for the location and removal of foreign objects from a difficult to access geometry utilizes a flexible lance (12) formed of individual hose bar segments (14) strung on cables (16) to give a structure that is flexible along its length and fairly rigid in a direction transverse to its length. Extending from working channels (18) of nozzle block (20) of the lance (12) are a pair of multi-prong retrievers (22). A miniaturized Videoprobe camera (24) is provided in the nozzle block (20) between the two retrievers (22). The retrievers are each connected to an actuating cable (26), which extends through the flexible lance (12) to a manual control (28). The camera (24) is connected by a cable (30) to suitable video processing circuits for generation of images on a video display (32). The cable (30) also houses a fiber optic bundle which conveys light to the area being serviced by the lance (12).
