Abstract: A heat exchanger includes two headers and tubes secured to and extending between the headers, each tube including a wall formed with a leading surface, a trailing surface and lateral surfaces extending between the headers and interconnecting the leading and trailing surfaces, a passage enclosed by the wall for carrying fluid between the headers, and long and short fins formed integrally with and extending outward from the wall.

Abstract: A socket tool is formed primarily from non-metallic composite material. The socket tool body is compression molded of high-strength, glass-reinforced vinyl ester sheet molding compound. Metal inserts are respectively received in the driven and driving ends of the tool body, the inserts respectively defining openings for respectively mateably receiving associated driving and driven members, the inserts being disposed in the body so that no portion of the inserts projects outwardly beyond the exterior surface of the body. The inserts are preferably insert molded in the body, but may also be fixedly secured in pre-existing recesses in the ends of the body, as by press-fitting or bonding. In the latter case, the inserts are provided with anti-rotation outer surfaces which are non-circular in transverse cross-sectional shape.

Abstract: A double-ended ratcheting box end wrench includes a body formed entirely of glass-fiber-reinforced plastic material with box-type ratcheting inserts molded at opposite ends of the body. The body includes layers of random discontinuous glass-fiber-reinforced plastic material and a band of unidirectional continuous glass-fiber-reinforced plastic material. The body is subjected to a compression molding process embedded within which are the ratcheting inserts to form a composite wrench structure. Each insert includes a two-part housing in which are disposed a ratchet gear, a pawl and a bias spring.

Abstract: Means for mounting a roll of tissue on a tubular member of a commode frame, comprising a U-shaped bracket having a pair of legs with a roller for supporting the tissue between the legs, and a U-shaped clamp which embraces the tubular member. Fasteners connect the ends of the clamp to the mid-section of the bracket for mounting the tissue on the commode frame.

Abstract: A wheelchair having means for releasably supporting a basket in front of the wheelchair occupant. The basket can be easily removed from the wheelchair by raising the basket above a pair of fingers mounted on opposite sides of the wheelchair. The fingers are carried by support means having a pair of laterally movable handles that engage the wheelchair frame.

Abstract: A container is suspended from the bolt that connects the handle of a crutch to the crutch side rails.

Abstract: A pick-up truck cargo box capable of transporting standard 4.times.8 foot construction panels in a flat mode even though the spacing between the wheel housings protruding into the cargo area is less than the width of the panels. The inner body panels 17 of the cargo box 10 are provided with recesses 19 having platform surfaces 21 adapted to support the ends of load bearing support members 25 extending laterally across the cargo area from side wall 12 to side wall 13. The recesses 19 are formed such that when a support member 25 is positioned with its ends on aligned surfaces 21 of the recesses, the top surface 26 of the support member will be at the same elevation as the flat upper surfaces 16 of the wheel housings 14 and 15.
