Patent DE-2051755-A1 (DE)
Title: Plaster - made from hard synthetic foam base
IPC: C04B28/02
Filed: 1970-10-22
Abstract: Plastering of ceilings, walls and plate shaped objects partic. with rough uneven surfaces is done with a granular powdery and/or fibrous low density material which is mixed with an aq. mineral binder and/or a synthetic resin binder to obtain a thick paste which is applied onto the surface to be plastered and is smoothened.

Patent DE-2107593-A1 (DE)
Title: Universal die - for extrusion of metals
IPC: B21C3/14
Filed: 1971-02-17
Abstract: The die which can be used for the drawing of tubes bars or wire of any metal of good mechanical properties has a system of tandem dies and a pressure socket which sticks outside the die through a hole in the pressure screw.

Title: Hydraulic brake system with leak detector - monitors reservoir fluid level and pressure and shuts off respective brakes
Inventor: LEIBER HEINZ
IPC: B60T8/1761
Filed: 1973-09-12
Abstract: The hydraulic brake system is fitted with an anti skid control in which the brake connection to the wheel cylinders is blocked, while the wheel cylinders are vented.
