Title: Operating mechanism for sound arms on record players - has accumulator connected to starting lever
Inventor: HOLMBERG FOLKE INGEMAR
IPC: G11B3/10
Filed: 1975-03-12
Abstract: An accumulator is connected to a starting lever in such a way that when the lever is shifted from its normal position to its working position the accumulator is charged. The sound arm remains in its normal position. A control device which causes the movements of the sound arm and is connected to the accumulator receives energy from the accumulator and swivels the arm out of its rest position into its starting position over the turntable by means of a cam or lever drive. It then lowers it onto the record and, if necessary, moves it back into the rest positiona after playing of the record is completed.

Title: Test unit for rapid transfer signal line - has address generator and signal combiner leading to a comparator
Inventor: JACOBI PETER ING GRAD
IPC: G11C29/20
Filed: 1975-04-17
Abstract: The test circuit relates to the testing of circuit networks worh a number of signal inputs, especially for a rapid storage device, and which has at least one signal output. A signal combiner passes the input string to a smoothing circuit, and this is followed by a comparator to regulate the level of the signals for the "O" and "1" signal pulses. Following the comparator is an intermediate store which is connected with a digital comparator, and this is in turn regulated by pulse oscillator. Provision is made to extend the output circuit to accommodate a number of parallel data exit lines connected with the same control circuit.

Title: Anti-arcing control for electric train pickup - has current monitoring control on primary current converter
Inventor: SCHACHER ROGER
IPC: H02H3/12
Filed: 1975-05-02
Abstract: The electric traction vehicle with overhead power supply has a current monitoring system in the high voltage input side of the transformer. The primary transformer current operates on threshold level switches which are coupled to solid stage control circuits. These operate the protection loops which prevent damage to the drive system if the pick-up contacts start to lift off the conductors e.g. at high speed. The system is more responsive than relay protection in the secondary circuits of the transformer.

Title: Hot and cold water mixing tap - has sliding piston with sealing ring located in groove and maintained leak-tight by water pressure
Inventor: ZWINK HELMUT
IPC: F16K11/078
Filed: 1976-01-22
Abstract: The hot and cold water mixing tap has a cylindrical body (1) with a spout (7) and a central piston (14). Sliding the piston (14) by means of the knob (20) controls the temperature by controlling the ratio of the hot or cold water which flows into the inlets (W,K). The flow of water past the piston (14) is prevented by the seal (36) which is of cylindrical form with the ends formed into O-rings (27) which fit in grooves in the bushes (8). The seal is pressed against the surface of the piston by the water pressure in the inlets (5,6) so that the sealing pressure is always adequate but never excessive. Wear of the seal is thus kept at a minimum.

IPC: C07C303/06
Filed: 1976-01-29
Abstract: Micellar dispersions of petroleum sulphonate, hydrocarbons and water are prepd. by (a) extraction of crude oil, (b) sulphonation of (part of) the crude oil with SO3 to give a prod. contg. a petroleum sulphonate, (c) neutralisation of the prod. with an aw. monovalent base to form a micellar dispersion used for injection into oil-bearing formations to displae further oil towards a prodn. bore-hole. Usual stages of refining crude oil to obtain a selected fraction, e.g. gas oil, sulphonating, sepn. of the sludge formed as by-prod., and mixing the components of the micellar dispersion, are eliminated with substantial economic savings. The simple equipment required can be sited near the oil well, with savings in transport costs.

Patent DE-2638984-A1 (DE)
Title: Automatic fabric winding machine - has two winding stations with controlled change-over to give high-speed working and reduce change times
Inventor: POISEL OTTO KARL DIPL ING
IPC: D02H5/02
Filed: 1976-08-30
Abstract: The automatic fabric winding equipment accepts fast-moving flat material passing at a high speed to form large coils. Two winding stations are used in a three stroke process. The first two cycles have the same value and each of them represent one-tenth of the third cycle. The winding station change is only effected during the second cycle so that in the first and second cycles both the winding stations are synchronised. Facilities for changing the wound fabric and the winding sleeve or dyeing beam are operated during the third cycle, however, using sufficient forces to handle various sizes of winding sleeves and dyeing beams. The design reduces the operating times for removing fully-wound beams and exploits the rotating forces of the winding beams to carry them clear of the winding zone.
