Title: Valve having rocker valve member and isolation diaphragm
Inventor: BAKER JOSEPH W
IPC: F16K11/02
Filed: 1993-03-12
Abstract: VALVE HAVING ROCKER VALVE MEMBER AND ISOLATION DIAPHRAGM     Abstract Of The Disclosure A valve having a valve body formed with a chamber with which a plurality of ports in the valve body communicate.  At least one of the ports is adapted for connection to a source of pressurized fluid.   A rocker valve member is pivotally mounted within the chamber and swings between two extreme positions in which it closes and opens at least one of the ports.   A diaphragm within the chamber extends from the periphery of the rocker valve member and the margin of the diaphragm is secured in the valve body.  All the ports in the valve body face one side of the diaphragm.   An operator, for swinging the rocker valve member between its extreme positions, engages the rocker valve member on the side of the diaphragm opposite the side facing the ports, so that the diaphragm serves to isolate the ports from the operator.   The chamber is defined in part by a wall facing the side of the diaphragm opposite the side of the diaphragm facing the ports, the wall being spaced far enough from the diaphragm so that when the portion of the chamber between the diaphragm and the port is pressurized, causing the diaphragm to swell in the direction of the wall, the wall is not engaged by the diaphragm.

Inventor: BARANOWSKI JOHN
IPC: B01F9/00
Filed: 1993-05-04
Abstract: A system for handling cylindrical cans or the like and conveying them from filler and closure equipment to and into hydrostatic sterilizer carriers.  After the cans have been filled and closed, they are conveyed upright to a receiving area.A screw assembly is periodically actuated, taking cans from the receiving area, grasping their cylindrical sidewalls and laying them down and forward into a metered can stick.  This can stick is rolled laterally by a clamp-kicker assembly into the hydrostatic sterilizer carriers as they are conveyed past it.  The screw assembly includes a pair of horizontally disposed screws, both rotatable downwar-dly and inwardly and with the axis of one spaced above that of the other.  With one complete rotation of the screws a can held therebetween on its cylindrical sidewalls is positively laid forward onto its side.  With an adequate supply of cans in the receiving area, the controlled rotation of the screws determines how manycans are laid forward to thereby form the can stick.  Also, if a sensor detects that a can being conveyed to the screws has fallen down then the rotation of the screws is automatically stopped.
