Patent number: 4722295Abstract: There is disclosed an article treating apparatus particularly apparatus for pressure-impregnating or vacuum impregnating porous articles such as metal castings. A holder for the articles or a metal basket containing them is disposed in an autoclave and can be rotated about a horizontal axis. It has a horizontal through-passageway so that articles to be treated can be simultaneously loaded at one end of the passageway and unloaded at the other end of the passageway by an indexing mechanism. The indexing mechanism has a plurality of pusher arms which can be moved laterally into the path of the articles and then moved horizontally to push the articles along rails into and out of the passageway. The holder is stopped at a predetermined rotary position in which a longitudinal slot is opposite the pusher arms so that unloading and loading may be effected simultaneously with a single movement of the indexing mechanism, a pusher arm passing completely through the slot.Type: GrantFiled: April 22, 1986Date of Patent: February 2, 1988Assignee: Ultraseal International LimitedInventor: Peter D.

Patent number: 4506687Abstract: A printed circuit processing apparatus includes a modular tank arrangement with each of the tanks receiving a printed circuit board to be processed on edge, or in other words vertically, and which guides the printed circuit board through the tank for processing without leaving marks or "tracks" on the sides of the board. The boards are driven by rollers on which the lower edges of the boards rest. The boards are held vertically through the use of a plurality of vertically spaced longitudinally extending wires. Spray nozzles are positioned on opposite sides of the boards and are simultaneously operated to generally equalize the pressure on the opposite sides of the board. The spray nozzles contain the necessary solutions for processing the boards, and the guide wires are small enough so that they don't leave any areas of the board unprocessed, nor do they leave "tracks". The modular tanks permit one or several operations in a continuous path with connecting sections between the modular tanks.Type: GrantFiled: June 10, 1982Date of Patent: March 26, 1985Assignee: Circuit Services CorporationInventor: Hubert J.
