Patent DE-1815407-A1 (DE)
Title: Sheet metal pipe elbow
Inventor: KOENIG RUDOLF
IPC: B21C37/28
Filed: 1968-12-18
Abstract: Process for producing large pipe elbows from thin walled pipe involves cutting of a straight pipe on a slanting cutter, after which the two pipe ends with a sharp angle to the cutting plane are cut off perpendicularly to the cutting plane, producing on both pipe sections similar but different sized cutting planes. The pipe wall of both pipe ends adjacent to the small cutting area is rounded outwards to form the inner elbow wall and the prepared sections are joined at the small cutting areas by welding. The large open cutting areas now lying in one plane are closed by an ellipsoid (Kalotte) to form the outer elbow wall.

Patent DE-1919308-A1 (DE)
Title: Stranded wire with composite insulation
IPC: H01B13/26
Filed: 1969-04-11
Abstract: The insulation is based on a layer of plastic braided with a fibrous material. The plastic layer is applied by cold, high pressure extrusion and the wire is then heat treated to polymerize the plastic and the braid loosely applied. This braid becomes slightly impregnated and polymerization continues. Finally the mesh is fully impregnated with the same or similar plastic and this impregnant is in turn polymerized. The insulation can be used for stranded wires, of seven strands for example, with only light pressure and without twisting.
Patent DE-1921883-A1 (DE)
Title: Plastics slide fastener with links at vary- - ing pitch
Inventor: W SPINDLER DIPL-KFM SIEGFRIED
IPC: B29D5/06
Filed: 1969-04-29
Abstract: Monofil plastics fed to the toothed wheel is circled round by a guide or tube so that the strand running lengthways along the fastener is twisted round the monofil and so inserts it in the turns formed on the wheel.

Title: Vehicle hydraulic power assisted braking system - has fluid pump connected to high level plunger cylinder via hydraulic reservoir
Inventor: ZABADNEH M KHALED DIPL ING
IPC: B60T13/14
Filed: 1973-07-11
Abstract: Depression of the vehicle brake pedal displaces a control valve which allows high pressure fluid to enter the plunger chamber. This fluid then flows into an auxiliary chamber at a lower level which is coaxial and mechanically connected with the main brake cylinder. The displacement of the upper plunger controls the vol. of high pressure fluid which enters the auxiliary chamber and thus controls the level of pressure applied to the road wheel brakes. Upon release of the brake pedal spring force in the lower chambers forces the fluid via a return connection in the upper chamber back into the reservoir.

Title: Infinitely variable toothed gearing - has planet gear orbiting fixed annulus to drive transversely displaceable output annulus
Inventor: LEUERMANN WALTER
IPC: F16H3/44
Filed: 1973-11-19
Abstract: The planet gear is supported on an input crankf for its orbital motion around the inside of the fixed annulus gear. The rotation of the planet gear is transmitted to the output annulus which is supported for being displaced between a position coaxial with the fixed annulus and a position transversely off-set therefrom. In the coaxial position of the annuli the planet gear rolls equally on both and the output annulus stands still. When the output annulus is displaced it participates in the orbital motion of the planet and has rotation whose speed increases with the extent of the displacement. The rotation of the output annulus is transmitted by cardan shaft to a fixed axis output shaft.
