Abstract: A single charge continuous rotary retort furnace for heat treating machine parts in a sealed atmosphere, including a rotary retort furnace housing having an inlet and outlet end with a feeder assembly at the inlet end that has a plurality of chambers for supplying the machine parts to the rotary retort furnace housing to be heat treated. In addition, the rotary retort furnace includes a locking collar assembly for connecting the feeder assembly to the inlet end of the rotary retort furnace housing having locking tabs for locking the feeder assembly to the locking collar assembly; pistons and cylinders for rotating the locking collar assembly relative to the feeder assembly; and a device for sealing the feeder assembly relative to the locking collar assembly to create an atmospheric seal in the retort furnace housing for enabling the machine parts to be heat treated.

Abstract: A masking apron dispensing apparatus comprises a base, a support member extending generally upwardly from the base, and at least one paper roll support unit mounted to the support member and extending generally perpendicularly therefrom; each paper roll support unit further comprising means for supporting a roll of masking tape adjacent at least one end of the paper roll support unit, means for facilitating positive pressure engagement of the tape against a roll of paper supported on the support unit, and cutter bar means for severing the paper and tape to a desired length. Each of the paper roll support shaft units may support two or more paper rolls and each may support two or more rolls of masking tape. As an alternative embodiment, a hand-carried single paper roll support shaft dispenser is also disclosed.
