Abstract: Toss game apparatus for alternate use as a target for thrown projectiles or as a support for supporting an individual playing the toss game includes a frame and a top panel mounted on the frame and deflectable relative to the frame. Interior support members attached to the top panel limit the degree of deflection of the top panel. Carpeting is positioned on the top panel having an upper layer of upwardly projecting fabric fibers angled toward one of the frame ends.

Abstract: An air-operated hammer is provided for removing risers or gates from castings. The hammer includes a piston having a rod to which an impact member is releasably latched. Operation of the piston is controlled by a pneumatic logic control circuit, the operation of which is initiated by simultaneously depressing a pair of thumb-operated pneumatic switches. When actuated, the control circuit acts to cause the piston to retract to cause the impact member to compress one or more blow-delivery springs, with the latch being automatically released, upon desired loading being achieved, to permit the release of the stored energy in the springs resulting in the impact member being impelled against a gate or riser to be broken off. Meanwhile, the circuit operates to reverse the direction of movement of the piston so that it extends to be automatically once again latched to the impact member.

Abstract: A system for delivering liquid catalyst to a core-making machine includes a single fireproof cabinet in which is located a catalyst storage tank. The storage tank receives catalyst from catalyst supply drums that are positioned one at a time in a pumping station located in the cabinet beside the tank and emptied into the tank by a barrel pump. A flash-off station is located in the cabinet beside the pumping station for receiving emptied drums and an exhaust hose, that is coupled to a scrubber system exhaust duct, is positionable within the drum to carry away vapors produced in the drum as residual catalyst flashes off. A catalyst supply pump is coupled for pumping liquid catalyst from the storage tank to a gassing unit of a core-making machine.
