Title: Helium mass spectrometer for leak detec-tion
IPC: G01M3/22
Filed: 1970-02-05
Abstract: Helium mass spectrometer for leak detection on buried cables. To locate any leaks in buried gas-filled high-tension cables or gas or water mains, the cavity is filled with helium.

Title: Red oxide phosphors recovery from colourtelevision - tube coatings
IPC: C01F17/241
Filed: 1970-03-21
Abstract: Oxidic phosphors, esp. Y or Gd-based colour phosphors activated with rare earths, are freed from impurities such as sensitisers, binders, additives and sulphidic phosphors by: 1) removing sensitisers, binders and additives by treating with water heating to 40-98, pref. 80-95 degrees C; 2) adding organic acid, e.g. acetic, citric and/or tartaric acids, their salts or alkaline reagents, e.g. alkali hydroxides or carbonates, besides strong complexing agents, e.g. gluconic acid, acetylacetone cation, amines or oxidising agent; 3) washing out solubilised impurities; 4) adding another oxidising agent and treating oxidic phosphor, pref. at elevated temp. so that sulphidic impurities are converted to oxides; 5) finally removing resultant oxides. Economical and safe technique permits recovery of very costly red oxidic phosphors from mixtures with green and blue sulphidic phosphors (ZnS, ZnCdS, Ag activated), binders (PVA) and other additives, as used in colour TV tubes.

Title: High pressure hydraulic brake master cylinder - has two brake cylinders of different dimensions with interconnected valve to give pressure step
Inventor: BALTZER SIEGFRIED
IPC: B60T11/224

Title: Vehicle weighing scales with weighing plate for load - has indicator connected to flexible pressure tube
Inventor: GRIFFIN COLIN JOHN
IPC: G01G5/04
Filed: 1973-10-17
Abstract: A supporting base braces an elastically deformable part with which the weighing plate interacts in such a way that the load placed on the weighing plate to be weighed causes deformation of the elastically deformable part. An indicator reacts to this deformation. The elastically deformable part is a sealed flexible tube filled with a liquid. The indicator is a pressure gauge connected to the flexible tube, which indicates the pressure of the liquid in the tube. This pressure gauge can be fastened permanently to the supporting base or not, as the case may be.

Centrally in the bow there is a conical kneading block linked by a rod to a pneumatic cylinder by which it can be lifted or lowered to open or close the discharge opening. The machine is cheaper, more compact and easier to empty even tough dough, whch can be discharged intermittently in quantities as required.
Patent DE-2424830-A1 (DE)
Title: Reaction time meter for light-plus-sound signals - which are given at irregular intervals after a ready signal
Inventor: SCHULZ AXEL ING GRAD
IPC: A61B5/16
Filed: 1974-05-22
Abstract: The person whose reaction time is being measured operates a switch in response to the appearance of a green light accompanied by the sound of a hooter. (START). Closure of the response switch (or, failing that, an overflow signal from the counter) produces a signal from an OR-circuit which trips a monostable multivibrator. The resulting pulse, by its leading edge, halts the pulse-train generator while the counter is read, and also lights a red lamp ready for the next test. The pulse trailing edge re-starts the pulse-train generator and triggers a random delay circuit which thereupon produces a pulse whose leading edge adds a yellow to the red light and whose (random) trailing edge zeroes the counter and simultaneously trips the bistable multivibrator, so dousing the red and yellow and lighting the green while sounding the hooter (L).

Abstract: Dog basket in storey form where the complete construction of rigid shape can be integrally produced from one piece or is made out of two individual beds. The top place can be adjusted in height to suit the animals size and the bottom section can be used as a cage or carrier box by fitting a closure such as a flap door or grating. The basket can also be of flexible construction when the device which keeps open the sack-shaped sleeping section can be swivelled or flapped over and the entry can then be held selectively open or closed, specifically by a belt spring or a tensioning loop.
Patent DE-2431738-A1 (DE)
Title: Safety valve in trailer air brake line - with pressure controlled operation to shut valve if trailer brakes leak
Inventor: BECK SIEGFRIED
IPC: B60T13/44
Filed: 1974-07-02
Abstract: The trailer pneumatic brakes are coupled to the towing unit brakes by a safety valve (22). This has a spring loaded valve element (32) pressed into a ring shaped seat (27) in a lateral section of the airline. The valve element is positioned over a ring shaped support (31) with fold back sealing lips (30) to isolate the spring from the air brake pressure. A bleed hole (26) bypasses the valve. If there is a leak in the trailer brakes then the downstream pressure drops thus closing the valve by the combined spring and upstream pressures. The automatic trailer safety brakes can then operate without delay, without draining the air pressure in the towing unit brakes.
Patent DE-2431837-A1 (DE)
Title: Coil former for shell core coils - flange between two bushes has blocks on opposite ends to locate coils

Title: Glider with manually operated flap - using pedal bars to move flaps and propel glider
Inventor: NAAKE LUDWIG
IPC: B64C31/04
Filed: 1974-08-16
Abstract: Each wing of the glide is fitted with trailing flaps. These are coupled to pedal bars (1) by means of connecting struts (3). The pilot is strapped into the seat and when he pushes the pedal bars down, either together, or in turn, the flaps are moved. Wind flow pushes the bars upwards again.
