Title: Hydraulic clamping nut with retraction feature - has primary and secondary hydraulic systems for retracting main piston into nut
Inventor: LOECKMANN HANS WERNER DIPL ING
IPC: B23Q3/08
Filed: 1975-07-19
Abstract: The hydraulic clamping element with internal primary hydraulic pressurisation system exerts high pressure for pushing out a piston. A second hydraulic pressurisation system is used for retracting the circular piston and also for reducing the pressure in the primary system. Both pressurisation systems can be remotely controlled by a common actuator for synchronisation to preventing faults which could readily occur due to an automatic synchronisation system. The secondary hydraulic system is associated with the cylindrical bore with an auxiliary piston. This piston has a central bore connected by a hexagon nut and rod to the pressurisation piston. This piston is retracted into the nut body when pressure in the secondary hydraulic piston is increased. The secondary hydraulic systems has a cylindrical annular space with two circular seals.

Title: Self regulating liquid valve for hose protection - closes when outlet pressure reaches maximum acceptable value
Inventor: OKAMOTO EIKI
IPC: F16K31/363
Filed: 1975-07-28
Abstract: A shut off valve for liquids is used to protect the outlet hose from excessive pressure. The valve has a cylindrical valve body (24) which at its ends is connected to inlet and outlet hoses (26, 62). A coaxial extension on the inlet side (32) carries a piston disc (36) which divides the interior of the valve into chambers. The chamber near the inlet side (50) exhausts to the atmosphere and it also locates a compression spring (56) which normally keeps the valve open. The second chamber (52) locates a seal disc (64) which is attached to the extension of the piston. When the outlet pressure is greater than the spring force, the seal (64) is pressed against the inlet extension, thus closing the valve.

Title: Sprung cash box lock - has plastic leaf spring-loaded bolt retracted by key bit protruding from slotted rotating centre plug
Inventor: RIEGRAF GERHARD
IPC: E05B65/00
Filed: 1975-08-08
Abstract: The cash box lock has a bolt (16) and housing (10, 11) in plastic material.
