Abstract: Vertically adjustable floating dock units for mooring boats are adapted to be vertically adjustable relative to the water line. The floating dock unit contains a detachable pontoon mounting assembly to which pontoons are secured and the assembly is removably secured to the dock understructure at variable vertical height adjustments.

Abstract: Floating docks units adapted to float freely in water as floating docks for mooring boats, comprising a longitudinal box beam understructure supported by a flotation unit integrally secured to the box beam member. The floating dock unit further contains an upper plank deck comprising a plurality of planks secured diagonally to the longitudinal box beam member. The diagonal planks in combination with the unitary understructure of the box beam integrally secured to the formed metal flotation unit provides substantially increased strength and structural integrity to the floating dock unit.

Abstract: A boat shoring system for cradling and supporting a boat in dry storage comprising two or more interconnected sub-system assemblies. Each sub-system comprises a central load bearing post and two laterally spaced outside supporting stands securely interconnected with laterally adjustable and angularly directed cable or chain means tautly stretched and preferably in tension to stabilize lateral movement. Two adjacent sub-systems are further stabilized by tautly stretched center cable means. The load bearing posts and outside supporting stands are vertically adjustable and transversely movable both laterally as well as forwardly and rearwardly. The boat shoring system can be easily assembled for use or dismantled into individual components and compactly stored during non-use.

Abstract: A circulating fan for annealing furnaces of the type having a centrally apertured circular base plate, a plurality of circumferentially spaced radially disposed main fan blades, mounted on one side of said base plate having a forwardly inclined concave scoop portion, one or more interceptor blades inclined in the same direction as the scoop and disposed between a pair of adjacent said main fan blades. A circular flat outer upper peripheral ring to which said main and interceptor blades are secured.

Abstract: A load support diffuser adapted to support a vertical stack of coils in an annealing furnace and means for cooling a protective atmospheric gas within said furnace, the diffuser comprising a flat circular base plate, a plurality of outer load support members secured to spaced portions of the outer periphery of the base plate, a flow deflecting ramp disposed between each pair of adjacent spaced outer load support members, spaced vertical radial inner load support members spaced inwardly on the base plate from the outer load support members, a cooling member disposed in an annular space provided in the diffuser between said outer and inner support members.
