The container includes a tray- or pan-like base having a rectangular back wall and obliquely-shaped side walls, a vaulted or domed lid comprising foraminous front and side wall portions which conform to and complement the walls of the base to yield an enclosable receptacle, and hinging means connecting the two along their mating front edges.

Abstract: An apparatus for cleaning a carpet which includes two reservoirs mounted on a frame over the rear wheels of a truck to store a supply of cleaning fluid which is heated in a heat exchanger is disclosed. The reservoirs reduce the sloshing of fluid when the truck is in motion. Pivot flanges are used to balance the reservoirs on the frame to provide effective transfer of the apparatus from one truck to another. The truck engine generates heat energy which is convectively transferred to the engine coolant fluid which is subsequently cycled through the heat exchanger. The cleaning fluid is also transported to the heat exchanger where heat transfer takes place between the cycling engine coolant fluid and the cleaning fluid. The cleaning fluid is heated to a higher temperature condition prior to being sprayed on and into the rug while the engine coolant fluid is cooled prior to being recycled through the engine.

Abstract: A means for protecting hoisting slings and/or their loads is described. The device includes a strip of uniform width and indefinite length comprising multiple plies of woven webbing, a plurality of spaced channels between a first pair of adjacent plies, and a plurality of friction straps, each secured at one end between a second pair of adjacent plies so that the opposed free end extends perpendicularly from a longitudinal edge of the strip. Each friction strap corresponds to one of the plurality of channels and is about as wide as its corresponding channel so that it fits snugly therein. The device is interposed between the sling and the load and is attached to the sling by encircling the sling cable with the straps and passing them through their corresponding channels so that the sling is firmly engaged by the device.

Abstract: A fluid discharge regulating device to be used for conserving water in the toilet tanks of bathroom toilets. The device includes partitions that divide the toilet tank into three consecutively arranged compartments, each compartment providing fluid communication with other compartments, either directly or indirectly, through portholes in each partition. Each porthole opening is adjustable to control the rate of fluid flow into the second or middle compartment in order to maintain constant the amount of water used during a single flush. The volume of fluid reaching the toilet bowl can be increased beyond the preset level by holding down an adjustable handle which is connected to the flushing mechanism.

Abstract: A chain saddle assembly is disclosed which permits a chain used as a sling to be supported at any point between its opposite ends.
