Abstract: The invention provides a water bath toy having a pump that draws water from a bath tub or pool and discharges the water back into the source. The pump is battery powered or hand powered. The invention includes a plurality of output options and a selector for choosing the active output feature. These features may include a narrow spray nozzle, a wide spray nozzle, a flexible hose, and a cascade with configurable obstructions that affect the water flow. The outer body of the water bath toy is configured to fit over the sidewall of a pool or bath tub.

Abstract: A refractory brick particularly suited for constructing a diffusor wall for an industrial heat source. The brick includes a substantially tubular body having a first end, a second end opposed to the first end, an inner surface defining a passageway extending in the longitudinal direction of the body from the first end to the second end, and an outer peripheral surface extending from the first end to the second end. The outer peripheral surface has a complementary shape that allows mating of a plurality of the bricks to form cooperatively a diffusor wall. Mating means is formed on or in the outer peripheral surface for engaging corresponding mating means formed on or in outer peripheral surfaces of adjacent bricks when assembled as a diffusor wall.
