Title: Pipe union for butt joined smooth pipes - has rubber seal stretched between telescopic sleeves to grip pipes when released
Inventor: VAHLBRAUK KARL HEINZ
IPC: F16L37/05
Filed: 1976-09-23
Abstract: The pipe union consists of two telescopic, cylindrical sleeves (3, 4) having end flanges which just clear the pipe diameter,. Internally, a cylindrical rubber seal (1) is attached to the Internal faces of the end flanges. When the sleeves are separated to their maximum extent, the rubber seal is stretched and spring loaded pegs (8) on one sleeve locate on the edge of the other to hold the sleeves apart. In this condition, the rubber seal is well clear of the pipes (9, 10) which may therefore be inserted easily into the union, the pegs with the joint positioned centrally in the union, the pegs are depressed, allowing the rubber seal to draw the sleeves together. As it does so, it grips the pipe surfaces securely and a good seal is made by the ridges (2) preformed on the internal surface of the rubber.

Title: Elastically sprung boot for sports use - has pneumatic ball between boot and flat base additionally connected by hinged levers
Inventor: WOLFF HANS-DIETRICH
IPC: A63B25/10
Filed: 1976-09-29
Abstract: The flexible spherical ball (1) houses two pairs of hinged levers (6-9) such that when they are vertically compressed they deflect in two directions which are perpendicular to each other.

Title: Low power safe-light for darkroom - has two or more LEDs and selective filters to produce narrow band spectrum
Inventor: KARL GERHARD DIPL PHYS
IPC: F21Y115/10
Filed: 1976-11-12
Abstract: The safelight for the darkroom has two or more LEDs mounted on a baseplate and arranged so that they provide a narrow spectrum of illumination (LTF).

Patent DE-2700431-A1 (DE)
Title: Compact portable fire extinguisher - has rotating bell shaped housing which expels extinguishing liq. when fusible element parts
Inventor: GOW QUINN W
IPC: A62C35/02
Filed: 1977-01-07
Abstract: A spring would bell-shaped dispensing housing is constrained against rotational movement by a band secured to the housing and a non-rotatable bottom plate. The band, which is locked in position by a fusible element, also serves to seal the liquid or chemical dispensing apertures which are peripherally disposed about the bottom portion of the bell-shaped housing. When the fusible element parts in the presence of an abnormally high temperature condition, signalling the presence of an incendiary situation, the band falls away from the bottom plate and the housing simultaneously permitting the spring would housing to commence rotating and the liquid or chemical extinguisher to be discharged through the peripherally disposed apertures. The rotating bell-shaped housing, through its generated centrifugal force, will expel the extinguishing liquid or chemical in a well defined circular pattern over the burning area.

Title: Stress free thermoplastic laminates - produced by passing individually controlled polymers through special combining head before laminating together hot
Inventor: CLOEREN PETER
IPC: B29C48/08
Filed: 1977-05-20
Abstract: Laminates of thermoplastic materials are produced by (1) passing the individual extrusion melts into separate feed passages and then into back-pressure chambers with larger section than the feed passages, using heat and pressure to remove stresses and effect uniform pressure distribution, (2) passing the material into a smaller section passage and producing uniform pressure along it, then producing a pressure difference corresponding to the viscosity equation. shear stress = (DELTA P)/2L h, where DELTA P = pressure difference between inlet and outlet, h = width and L-length of the passage, and (3) producing a melt laminate at the outlet. Processing allows smooth individual control and flow rate of each copolymer according to its viscosity. Uniform laminates are produced with different thickness of individual layers. The process 'dememorises' stresses in the layers.

Title: Dishwasher machine with low water consumption - has timer-controlled twin contacts for matching spray time with fluid pressure in inverse proportion
Inventor: EIERMANN RUEDIGER
IPC: A47L15/00
Filed: 1977-08-10
Abstract: The dishwasher machine has a control unit with at least two contacts of which at least one can be moved slowly by a timer switch towards a stop when the program control unit is switched off during the cleaning program cycle.
