Title: Hydraulic screw press drive - has limit switch actuable by downward travel of press slide to open shut=off valve permitting fluid flow to actuate pneumo-hydraulic piston
Inventor: KONONOV IVAN VASILIEVITSCH
IPC: B30B1/23
Filed: 1978-09-29
Abstract: The drive of a hydraulic screw press comprises a power cylinder incorporating a movable member connected with the press slide.

Title: Turning device for tractor-mounted rotary plough - has connecting line between control valve and control instrument
Inventor: PUSCH GERHARD
IPC: A01B3/421
Filed: 1978-11-04
Abstract: The turning device is for a tractor-mounted rotary plough. It has a double acting hydraulic cylinder, a control valve and a control implement with an axially displaceable control slide which changes over the piston motion of the hydraulic cylinder and thus the movement of the plough from the first rotary phase into a second rotary phase.

Title: Wire reinforced safety glass - mfd. by heating two fusible glass panes enclosing steel wires
Inventor: LECHNER FLORIAN
IPC: B32B17/10
Filed: 1979-04-09
Abstract: Safety glass with an embedded steel wire reinforcement for open air use is made by using two panes of fusible glass and laying the wires between them in such a way that they keep clear of the rims and reinforce any parts with higher stress, for example suspension holes. The whole is then heated in a kiln until the panes fuse together. Glass panes, each 6 mm thick, are fitted with a system of heat resistant steel wires and heated to 780 degrees C. After a cooling time of 10 hours, a solid safety glass is produced. This does not suffer from corrosion like ordinary wire glass where the wire ends are exposed. Highly stressed parts can be taken into account.
