Inventor: MOIK FRANK
IPC: G08B27/00
Filed: 1975-08-11
Abstract: The burglar alarm pair of elements consists of an ultrasonic transmitter unit and a matching receiver unit which detects Doppler shift in the received signal.

Title: Stress-free semiconductive epitactic film on substrate - with stress-absorbing intermediate layer
Inventor: KASPER ERICH DR
IPC: H01L21/20
Filed: 1975-12-16
Abstract: Epitactic deposition of a thin monocrystalline layer of a semiconductive material on a substrate, with an intermediate layer, is improved in that the intermediate layer is formed in such a manner that the difference between the natural interatomic distances in the intermediate layer and the substrate is larger than the difference between these distances in the epitactic layer and the substrate. The thickness of the intermediate layer, however, is such that the actual interatomic distances in the intermediate layer are equal to the natural interatomic distances in the epitactic layer. Used partic. for the prodn. of luminescent diodes and photocathodes. The epitactic layer is free of stresses which are absorbed by the intermediate layer whose thickness is such that stresses do not exceed breaking threshold. Thus defects arising from heteroepitaxy are diminished.

Title: Electromagnetic control valve - has armature guided in linear ball bearings to minimise friction
Inventor: EGG MAX
IPC: F16K31/06
Filed: 1976-03-31
Abstract: The electro-magnetic valve has a housing (22) with an end cap (6) forming part of the magnetic circuit. The other end cap (13) is provided with the inlet connection (11) and outlet (24).

Title: Coal gasification under pressure - in pressure-tight cyclone and precombustion chamber with refractory embedded cooling tubes
Inventor: WIEHN HELMUT DIPL ING
IPC: C10J3/86
Filed: 1976-04-23
Abstract: Ground coal is gasified in a cyclone, lined with a refractory lining cooled by water tubes. The coal is pre-gasified in a pre-combustion chamber from which the mixt. is injected tangentially into the cyclone. Pressure-tight shells surrounded both cyclone and preheating chamber so that both can be operated at 20-35 atmos. The higher pressure results in a higher specific throughput. The cyclone, acting as after-combustion chamber and separator, raises the velocity of the coal particles, thus producing their complete gasification. The fused slag protects the walls against erosion and permits temp. as high as 1700 degrees C.
Patent DE-2618576-A1 (DE)
Title: Forced cooled cable installation - has separate coolant pipes welded to joint boxes to improve heat transfer
Inventor: GOSLING CYRIL HENRY DR
IPC: H02G15/24
Filed: 1976-04-28
Abstract: The cooling medium for a high duty cable, typically water, is passed through pipes (3, 5) which form part of a coolant circuit controlled from one point. Where there is a cable joint box (2) the pipe (4), or several such pipes, are welded to the surface of the box in order to improve heat transfer characteristics. To fill the water system a flexible, deformable plug is inserted at one pipe terminal and forced through the complete pipe loop by the water pressure behind it. As the plug forms a seal between air and water all the air is expelled from the pipe as it passes along. No air locks therefore result during filling. The system may be emptied in a similar manner by forcing the plug through with air pressure.

Title: Tanning animal hides - using powdery mixt. contg. trivalent chromium cpd. and magnesite acid binder contg. magnesia and lime

IPC: C14C3/06
Filed: 1976-04-29
Abstract: Powdery mixt. for tanning animal hides contains >=1 trivalent Cr cpd., in a quantity corresponding to 3-35% Cr2O3 in combination with 0.5-25% magnesite, contg. 60-90 (70-86)% MgO and 0.6-15 (2-5)% CaO. Magnesite acid-binder is opt. combined with other acid-binders. In an example, 100 pts. wt. powdery extract, prepd. by drying basic Cr sulphate and reaction prods. of hexavalent Cr cpds., and which contained 25% Cr2O3 having basicity 33%, was mixed with 6 pts. wt. powdery magnesite contg. 3.5% CaO and 85% MgO. Mixt. is a self-basifying Cr extract. No basifying or neutralising reactions take place between Cr cpds. and magnesite in absence of water. Basicity of Cr cpds., in transport or storage is unchanged. In use, basifying rate is even, alkali capacity of magnesite is used up and tanning is accelerated.

Title: 2,6-Di-tert-butyl 4-methyl phenol prepn. by hydrogenolysis - of N,N-dimethyl 3,5 -di-tert-butyl 4-hydroxy benzylamine with prod. as solvent
Inventor: ABRAMOW IWAN JEGOROWITSCH
IPC: C07C37/50
Filed: 1976-06-08
Abstract: is prepd. by catalytic hydrogenolysis of N,N-dimethyl-3,5-di-t-butyl-4-hydroxy benzylamine in the presence of a catalyst contg. Ni, Ti, Al, and using, as solvent, 2,6-di-t-butyl-4-methylphenol. The product is used as a stabiliser and anti-oxidant, e.g. for natural and synthetic rubber, polyethylene and polypropylene fibres, and food products. The known process above is carried out usually in an organic solvent e.g. decalin as in GB 1229480. However, in the reaction conditions, some resin is formed and the isolated product contains about 5% resin. The recovery of solvent is complicated and the product must be purified, e.g. by distillation, or crystallisation, for food uses. The above modification avoids any solvent recovery stage and gives a yield of product about 98.4%, which is satisfactory for food use without further purification.
