Title: Joint between steel wire reinforced rubber belts - differentially spaced textile cords embedded across belt join above and below wires
Inventor: HEYNHOLD INGO DIPL ING
IPC: F16G3/10
Filed: 1975-03-18
Abstract: A method of making a joint between two lengths of steel wire reinforced rubber belt uses a layer of textiles cords above and below the steel wires, at right angles to the latter and which are subsequently embedded in the joining portions of the rubber belts. These cords are spaced closer together at the centre of the joint than they are at the outer extremities of the joint, while the ends of the steel wires are staggered in the joint region. The cords are of smaller diameter than the wires, and those in the load carrying side of the belt are shorter than those on the opposite side. The spacing between the cords furthest from the centre is several times the spacing between the middle cords.

Title: Ultrasonic flow velocity measuring instrument - is for open or closed channels with free oscillators giving rapid reading even with solids present
Inventor: MUSTON ALBERT HENRY
IPC: G01F1/66
Filed: 1975-07-23
Abstract: A flow velocity meas. instrument has two pressure wave pulse transceivers transmitting pulses towards each other. An oscillator produces two frequencies dependent on the transmission time of the pulses from first to second transceiver and from second to first transceiver respectively, and a differentiator determines the difference between the frequencies. A sign detector (61, 62, 63, 64, 65, 66) establishes which frequency is the higher. The oscillations or pulses of the difference frequency are counted by a bidirectional counter (67) which is set by the sign detector so that its counting direction depends on which frequency is the higher.

Title: Storage container for tape cassettes - has spring loaded push button ejection mechanism and automatic cassette locking
Inventor: ACKERET PETER
IPC: G11B23/023
Filed: 1975-10-13
Abstract: The storage container for magnetic tape cassettes or cartridge comprises a rectangular housing open at one of its narrow edges to receive a cartridge.

Title: Embolising media based on silicone rubber - contg. X:ray opaque material
Inventor: SCHOEPFLIN GISELA DR
IPC: A61K49/04
Filed: 1975-10-30
Abstract: Embolising media comprise a low-temp-vulcanising silicone rubber mass in combination with an X-ray opaque material. The silicone rubber mass can be injected in particulate (vulcanised) form or in liq. (unvulcanised) form, together with BaSO4 or Ta as X-ray opaque material. The prefd. silicone compsns. comprise (A) 45-90 pts. wt. of a polysiloxane with a viscosity of 700-7500 cS at 25 degrees C; (B) 5-50 pts. wt. of an organosiloxane copolymer; (c) 5-11 pts. wt. of an organohydropolysiloxane; and (D) a catalytic amt. of Pt or a Pt cpd. The embolising media, which induce thrombus formation when injected into blood vessels, can be used for therapy of inoperable kidney tumours, various forms of haematuria and arteriovenous cerebral malformations. The media are easily injected (e.g. by means of an arteriographic catheter) to form a mass with good tissue compatibility which is permanently located and not subject to enzymatic or cellular degradation. The position of the mass can be located by radiography.
Patent DE-2549020-A1 (DE)
Title: Dry safety installation for acetylene - has reverse flow control with flame blow back and afterburning control incorporated in single valve
Inventor: ROST EBERHARD ING GRAD
IPC: F23D14/82
Filed: 1975-11-03
Abstract: The safety sampling point is for middle pressure acetylene circuits. Acetylene circuits must have devices to prevent reverse flow of gas also to avoid flame blow back by controlling mixture and flow and to prevent after burning. All three safety requirements in a single unit. The pressure shaft is in a single valve with a single membrane. The guide spigot of the valve centre is kept separate from the screw holding the control membrane. A minimal pressure causes flame cut off and a pressure increase produces the necessary locking by clamping the sealing sphere against the valve seat.
Patent DE-2554178-A1 (DE)
Title: Bearing for moving coil measuring instrument - has fluid damping with spring loaded inner sliding spindle sleeve
Inventor: KRAEMER LUDWIG DIPL ING
IPC: G01D11/02
Filed: 1975-12-02

The jewel (11) is fixed in an inner sleeve (12) containing the damping fluid. The sleeve is fluid-tight at the end opposite to that (14) at which the spindle (15) enters. The inner sleeve (12) is capable of axial movement in an outer sleeve (13), and is pre-loaded by a spring in the direction of the spindle. The jewel may be pressed into the inner sleeve or bonded in position. The axial movement of the inner sleeve is limited by a stop (18) such as an annular flange on the outer sleeve.
Patent DE-2556218-A1 (DE)
Title: Automatic adjustment of tool distance in flame cutting metals - by use of capacitative measuring electrodes whose output is corrected by compensating electrode
Inventor: SOFFKE WALTHER DIPL ING DR
IPC: B23K7/10
Filed: 1975-12-13
Abstract: Measurements of the distance between the nozzle and the plate is subject to faults when the electrode projects over the edge of the plate. The electrodes are so arranged that the distance between the proportion of their areas projecting over the edge is constant and independent of this distance. The signal from the correcting electrode is proportional to the control difference and through feeding via a suitable adjusting unit in the control circuit corrects the control signal from the measuring electrode. The process allows accurate operation of measuring systems near the workpiece edge where the projecting electrode gives false signals.
Patent DE-2600063-A1 (DE)
Title: Emergency call branch transmitter - is connected through main switch as extension to public telephone network
IPC: G08B25/08

Abstract: The circuit arrangement comprises a telephone terminal jack (1) connected with a main button switch (2), call number automatic response unit (3), miniature tape recorder (4), parallel set of push buttons (5), speaker control switch (6) and loudspeaker (7). When one of the several push-buttons (5) is operated, the automatic transmitter for an emergency call is started, and then the miniature tape recorder (4) with a short endless tape loop. A prerecorded message and address are then repeatedly transmitted through a magnetic head and an amplifier. The system may be used to transmit emergency messages to the police without the need for actual speech delivery through the normal public telephone receiver.
Patent DE-2601980-A1 (DE)
Title: Audio mixer for LF signals - compares single or several LF signals with part of whole sum signals
Inventor: KRAUS ULRICH
IPC: H04H60/04
Filed: 1976-01-20
Abstract: The audio mixer for LF audio signals tests single or several LF signals by comparing with a part sum or whole sum of several LF signals. These signals are tested without affecting the simultaneous transmission of the whole or part sums of all signals. Single or several signals can be tested alone: the same applies where the part and whole sums are concerned. The level of the tested signal is always the one that it has in the sum being compared with it. The mixer has two modulation paths formed by operational amplifiers.

Title: Filtering of liquids contg. solids and ionic contaminants - by division into partial streams and use of granular filter bed
Inventor: WIELAND GUENTER DR RER NAT
IPC: B01D24/38
Filed: 1976-03-12
Abstract: Mechanical and chemical treatment of liq. media contg. solids and ionic contaminants comprises dividing the liq. into several partial streams which are introduced parallel to each other into a granular filter bed at different locations distributed uniformly over the cross-section of the bed, to flow perpendicularly to the axial direction through sections of the bed. After treatment, the liquid is withdrawn from the filter bed in several parallel partial streams which are distributed uniformly over the cross-section of the bed. By increasing the input and output area and reducing the liq. streams, the rate of flowin each individual partial stream is reduced, allowing optimum treatment.
