Abstract: A utility truck with arched reinforcing rods incorporated into the base of a plastic truck during molding. The reinforcing rods are held in place in a mold at a predetermined distance above the mold's inner surface by spacers attached to the ends of the rods. Plastic is molded around the rods, with more plastic provided below the rods than above them, so that, when the plastic truck is removed from the mold and allowed to cool, the plastic will contract to a greater extent than the metal rods, causing the base and the reinforcing rods to bow upward, creating a convex arch in the truck's base. The arch provides an inherently strong, bridge-type structure that substantially strengthens the load-bearing capability of the truck, yet requires less reinforcing material than conventional supplemental chassis structures. In another embodiment, caster base mounts are also molded into the bottom of the truck, providing a utility truck with a unitary chassis structure.

Abstract: A liquid containment pallet for supporting a plurality of containers containing liquids, the pallet comprising a unitarily molded confined basin defined by integral sidewalls and a bottom wall, the bottom defining integral transverse passageways for receiving the tines of a forklift for lifting and moving the pallet; the pallet further comprising a unitarily molded platform for supporting the containers and preventing the containers from sliding relative to the platform in a plurality of integrally formed recesses, each defined by a cylindrical sidewall and a bottom wall, the platform further including a plurality of downwardly projecting legs for supporting the platform with respect to the basin, at least one of the legs defining a trough for receiving spillage and including drainage provisions for communicating the spillage to the basin.

Abstract: A molding apparatus is provided which consists of three frames which are relatively pivotal with respect to one another. One frame (A) is cradled in a second frame (B) and provision is made for tilting the first frame relative to the frame in which it is cradled. The cradling frame and the frame cradled therein are made tiltable relative to third frame (C). The tilting operations are effected by hydraulic piston and cylinder arrangements (170, 176). The method of the invention consists of cradling the first frame in a second frame, tilting the first frame relative to the second frame to a certain angle of inclination and thereafter tilting the cradling second frame along with the cradled first frame therein to a second angle of inclination relative to the third frame.

Abstract: A hamper for collecting items, such as soiled laundry, includes a cylindrical receptacle wall having a reception entrance at the top and a delivery port at the side, the delivery port being selectively opened or closed by a cylindrical sleeve which overlies the receptacle wall and can be rotated relative thereto, and a liner within the receptacle for receiving the items placed therein through the reception entrance and for being withdrawn through the delivery port, when the sleeve is rotated to open the delivery port.
