Title: Pressure-operated container for viscous products - has piston with circumferential continuous tail connected to and axially spaced from sealing band
Inventor: SCHULTZ ROBERT S
IPC: B65D83/14
Filed: 1978-08-04
Abstract: The container piston includes, adjacent the head end, a flexible circumferential band which lightly contacts or is expandable in the presence of loading pressure exerted by propellant gas. The band thus develops light sealing contact with the interior wall surface of the container, and such contact effectively isolates unexpelled product from the gas-pressure side of the piston, regardless of the extend to which product has been expelled. The piston further includes circumferentially continuous tail structure which is connected to and axially spaced from the expandable band and which serves to stabilise the piston against malfunction in the course of its single product-expelling stroke.

Title: Printing press pull guide - has lever mechanism determining roller and side stop movements against spring action
Inventor: DEISTING HORST
IPC: B65H7/12
Filed: 1979-05-29
Abstract: The printing press pull guide head slides along a cross-member for the entire width of the sheet, and is moved periodically by the member towards the sheet for the alignment operation. A spring-loaded roller in the head periodically presses the sheet against a pull rail underneath, while on either side of this roller there are spring-loaded side stops sliding in the head. Depending on the sheet edge to be aligned, one or the other of these slides forward into the working position, in which it acts against a fixed stop on the press. To give multiple sheet monitoring, a lever mechanism (40,42) determines the difference between the periodic movements against spring action of the roller (4) and the active side stop (11 or 12). When this difference exceeds a predetermined value a switch is thrown.
