  • Patent number: 4722295
    Abstract: 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.

  • Patent number: 4714086
    Abstract: A method for washing and drying a substrate and an apparatus therefor are disclosed which are capable of effectively rapidly carrying out the washing and drying of a semiconductor substrate in good yields without damaging and contaminating the substrate. The method comprises the steps of immersing a carrier carrying at least one substrate thereon into wash liquid; drawing up the carrier from the wash liquid while oscillating the substrate; and feeding drying gas to the substrate during the drawing-up of the carrier to remove the wash liquid from the surface of the substrate. The apparatus of the invention is constructed to allow the method to be effectively practiced.

  • Patent number: 4531821
    Abstract: A transport mechanism has two driven gears driven by a driving gear therebetween and having pivotally attached cranks at pivot points maintained at the same elevation as the driven gears rotate. The upper end of the cranks are attached to a horizontal moving guide bar. The moving mechanism is supported beside a fixed guide plate formed with a loading slot at the input end, a sloping edge at the output end and a number of equally spaced vertical slots therebetween. A film carrier has end rods which may rest on the moving guide bars and be lowered in the slots. Film chips in the film carrier advance from the loading slot into a developing tank. The mechanism then lifts the carrier with the film chips above the carrier tank and into a wash tank, then from the wash tank into a fixing tank, then from the fixing tank into a wash tank, then into a drying chamber and then upon an output ramp.

  • Patent number: 4506687
    Abstract: 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.

    Abstract: The same baskets are used to dip successive batches of parts into a path of cleaning fluid or the like, and between dips the baskets are raised to a position in which rails on which the parts are held in the baskets connect with intermediate rail pieces to form a continuous track so that the contents of each basket can be advanced to the next basket (or to the unloading station in the case of the last basket) while a new batch of parts is loaded into the first basket. The transfer operation is performed by a rake mechanism. The advantage is obtained that when the baths of cleaning fluid are at different temperatures, heat is not wasted in warming up and cooling the baskets and, furthermore, cleaning fluid is not lost by being carried away by baskets moving through the system.

    Abstract: An apparatus for conveying tubular members along a plurality of treatment liquid tanks in pickling facilities. The apparatus includes a pair of guide rails and a travelling car adapted to reciprocate on the guide rails. The travelling car includes at least one pair of tube-supporting hooks which can be reciprocated upwardly and downwardly and turned between positions parallel to the rails and other positions perpendicular to the rails. The tube-supporting hooks can be lowered or raised independently so as to support the tubular members aslant near the treatment liquid level in each of the treatment liquid tanks, thereby allowing immersion of the tubular members into the treatment liquid or retraction of the tubular members out of the treatment liquid without forming considerable air bubbles in the liquid. Since such bubbles are known to develop stains on the tubular members, tubular members of high surface quality can be obtained.

The separation fluid enters the separator at the bottom with sufficient force to form a mixture with and agitate the material to be separated. Lighter material is caused to rise toward the fluid surface and the heavier material is caused to settle to the separator floor by gravity. The force supplied is sufficient to cause the fluid mixture to pass forwardly through the length of the separator and thus the fluid mixture has a tendency to flow downstream toward the bottom end of the separator.

  • Patent number: 3961637
    Abstract: Apparatus for washing aggregate material comprises a cylindrical drum including first and second end walls having central openings defining respectively an outlet and an inlet. The drum is inclined from the horizontal to provide flow of the aggregate material toward the outlet along the interior of the drum. The drum is mounted for rotation on its longitudinal axis, driven by a tangentially engaged chain and sprocket, and is supported and stabilized by a system of guide rolls. The drum contains a series of longitudinally extending agitator vanes spaced around the cylindrical inner wall of the drum. As the drum rotates, the vanes agitate the aggregate material in the presence of wash water for efficient aggregate cleaning. A series of scoop-shaped flume elements attached to and abutting the outlet end wall bodily rotate with the drum.

  • Patent number: 3949770
    Abstract: A commercial dishwasher comprising two or more modulars connected together through which dish-carrying baskets are moved for washing and rinsing the dishes, one or more of the modulars being arcuate-shaped so as to alter a straight line movement of the baskets into one where they are swung through a 90.degree. angle. By connecting two of the arcuate-shaped modulars together, it is possible to swing the dish-carrying baskets through an arc of 180.degree.. Therefore the dishwasher can be positioned in the corner of a room and thus make use of space that would otherwise not be used.
