Patent DE-2557978-A1 (DE)
Title: Constructional members demountably anchored - with direct anchorage in earth concrete or rock using screw or bayonet fixing
Inventor: STUMP SIMON DIPL ING
IPC: E21D21/00
Filed: 1975-12-22
Abstract: The constructional member is given a screw thread which fits inside a closed, screw-threaded tube embedded in the ground. The space between is grease packed to inhibit corrosion and facilitate de-mounting later, should this become necessary, and any exposed length is plastic covered to protect it meanwhile. As a precaution against the screw thread binding and resisting unscrewing, the outer tube is made to fracture. It may be made in short lengths with weak (but waterweight) joints between them, or in one piece in a brittle material like gray cast iron or a ceramic. Developed versions provide for distance pieces to centre the fixture in its concrete-filled hole and for the concrete filling to include watertight expansion joints.

Inventor: GERHARDT WILFRIED DIPL CHEM DR
IPC: C07C17/08
Filed: 1975-12-27
Abstract: Vinyl chloride is prepd. from C2H2 and HCl, with heating, in the presence of HgCl2/active C catalysts. Initial gas mixt. is reacted incompletely, at 110-150 degrees c, in a 1st reactor packed with already spent catalyst. gas mixt. is then after-reacted in a 2nd reactor, packed with fresh catalyst, at 70-115 degrees C. Pref. reaction gas leaving 1st reactor may be cooled to 25-70 degrees C in a heat-exchanger, before after-reaction in a 2nd reactor. Initial gas mixt. pref. contains C2H2 and HCl in vol. ratio 1:1 to 1:1.2. Initial gas mixt. may contain, by vol. 42-50% C2H5, 45-54% HCl and 0-10% inert impurities, gaseous under the reaction conditions. Catalyst is used up better. Vinyl chloride quantity/kg fresh contact can be doubled.

Title: Quenching hardening system for steel tubes - has additional induction furnaces ensuring uniform tube temp. without blank tubes
Inventor: REINKE FRIEDHELM DR ING
IPC: C21D1/42
Filed: 1976-01-14
Abstract: System for quenching and hardening of steel tubes has a continuously operating furnace for tube heating. The tubes pass through the furnace in longitudinal direction and through a quenching station downstream of the furnace. An induction furnace between the furnace and the quenching station heats successive tubes to quenching temperature. The successive tubes with slight or no gap between them are heated without interposing blank tubes to a uniform temperature even if the tube wall thickness varies. The furnace has a preheating stage for the adjustable heating of the tube. This upstream connected preheating stage can be also an induction furnace. The preheating stage has a measuring system for analysing the tube wall thickness.

Title: Remote control stereophonic replay system - automatically adjusts sound balance to listener's position using ultrasonic signals
Inventor: GOEDDE JOSEF
IPC: H04R5/02
Filed: 1976-04-27
Abstract: The remote control, for stereophonic and quadrophonic replay systems, automatically adjusts the sound balance to the position of the listner. It can also control the volume independently of position and the on/off switch. Each loudspeaker has its own ultrasound receiver. The listener carries the ultrasound transmitter. The volume at each loudspeaker is made inversely proportional to the average intensity of the ultrasound reacing the receiver for that loudspeaker. The ultrasound is amplitude or frequency modulated to prevent interference at the re receivers. The volumes set by the receivers can be held. By varying the amplitude of the signal transmitted the volume of both loudspeakers can be adjusted together. If the transmitter remains off for a given time the sound system automatically switches off.

Patent DE-2635259-A1 (DE)
Inventor: BIERI HANS
IPC: F16K1/38
Filed: 1976-08-05
Abstract: The valve needles (12, 12') are pressed onto their valve seating surfaces (21, 21') and raised from them by means of hand wheels (25). The outlet bores (14, 16) extend transversely to the valve needles (12, 12'). Between each of the valve seating surfaces (21, 21') of the housing and the associated outlet bores there is a pressure chamber (13) in the form of a bore (15) surrounding the valve needle in a leaktight manner. As a result, the release of the flow takes place in two stages and cavitation phenomena at the valve seating surfaces (21) are thereby avoided. <IMAGE>

Title: Fault locator for circuit assemblies - produces individual part circuits and stores and compares data related to discrepancies
Inventor: SCHIRGE PETER
IPC: G01R31/28
Filed: 1977-06-30
Abstract: The assemblies are tested by a program controlled testing device. It has a coupler connected by a first line plane to a distributor in the assembly, and by the other line plane to test and measurement units. Each point of the distributor is individually connected through the coupler to each measurement unit, so that in each test step closed circuits are produced in the assembly, which mostly represent parts of extensive function circuits. When a deviation from a programmed values appears, the numbers and marks of all points in circuits produced in the corresponding step are stored. The store is connected to a comparator which, starting from the stored connecting points marks in an initial test step with smaller number of point markings, consecutively tests the stored marks of all test steps for coincidence of at least two with those of the initial step. Then a new initial step is derived from the steps with fewer coincidences, and thus two test steps with at least two identical point marks are determined.
