Patent DE-2825631-A1 (DE)
Title: Stripping welded thermoplastic blanks from continuous band - using device which grips blanks and waste at seam and tears obliquely (OE 15.12.78)
Inventor: KHU PETER
IPC: B26D7/18
Filed: 1978-06-12
Abstract: Workpieces of thermoplastic materials hot-blanked from a continuous band or film are sepd. from the waste to which they stil may be attached in places, automatically. The blanks may simply be profiled by heated tools, or may be formed by simultaneous blanking and welding two or more bands or films together. The waste is clamped very close to the periphery of the blank, and the blank is clamped very closed to its periphery, for pref. over its whole area under spring loading. The two are then sepd. by displacement of the clamping tools relatively to each other and through the plane of the workpieces. This transverse relative displacement of the clamping tools occurs at one point of the periphery in advance of the remainder.

Patent DE-2831213-A1 (DE)
Inventor: UEDA MAKOTO
IPC: H02P8/02
Filed: 1978-07-15
Abstract: In an electronic watch a non-operation detecting circuit detects the non-operative condition of the stepping motor of the watch and produces a non-operation signal each time the stepping motor fails to operate in response to the standard pulse which drives the same. A counter counts the number of non-operation signals and stores the count for later use. A rotation detecting circuit detects the resumption of operation of the stepping motor in response to the standard pulse from the non-operative condition and a quick feed control circuit quickly advances the stepping motor in response to an input from the rotation detection circuit by thereafter supplying, instead of the standard pulses, the quick feed pulses to the drive circuit for the motor equal in number to the number of the non-operation signals counted in the counter. In this way the corrected time will be displayed by the watch even after being rendered inoperative as a result of an external condition such as low temperature or a high strength DC magnetic field.

Title: Pressure regulator for compressed air systems - maintains constant reservoir pressure with facility for compressor unloading using control piston operating double seat piston arrangement
Inventor: STROBEL GUENTHER
IPC: F04B49/02
Filed: 1979-03-09
Abstract: A pressure regulator for use in an air brake system is used to maintain a constant pressure in a reservoir and to provide unloading of the air compressor supply. The compressed air outlet of the compressor is supplied to the inlet of the regulator and is passed to the reservoir over an outlet containing a non-return valve. A control passage connects the reservoir to the underside of a control piston that is subjected to a bias pressure. The control piston operates against a double seat piston arrangement. If the reservoir pressure exceeds the set value, the piston assembly moves downwards to open an unloading valve, allowing compressor air to be discharged to atmosphere.

Title: High quality crystal pulling - assisted by centrifugal acceleration raised in specified steps
Inventor: MUELLER GEORG DR
IPC: C30B15/24
Filed: 1979-08-22
Abstract: The Parent Patent No. 2842605 described a method for the production of high-quality single crystals, for use in electronic or electro-optical semiconductor devices, in which a strong convection flow is assisted by centrifugal action. It is now suggested to adjust the contant convection flow on the centrifuge by raising the centrifugal acceleration up to the desired figure in steps of less than 0.1 g (0.05 g). This is a safe way of eliminating the undesirable oscillatory flow conditions which are caused by steps of over 1g.

Inventor: GRADL REINHARD DIPL CHEM DR
IPC: C01B25/237
Filed: 1979-11-14
Abstract: The invention relates to a process for the purification of wet-processed phosphoric acid with the aid of organic solvents which are immiscible or only partially miscible with water, the sulfate ions being removed by addition of barium compounds. The purification is carried out in an n-stage extraction installation, where n is equal to or greater than 5. The barium compound is added to the phosphoric acid to be purified, and the resulting mixture is fed to the top of the extraction installation, in which the organic solvent phase is dispersed in the aqueous phase. The sulfuric acid is led in counter-current fashion to the phosphoric acid by adding it to one of the stages n=4 to at most n-1.
