Patent DE-2500537-A1 (DE)
Title: Pressure limiting valve - has double action sliding piston working against helical spring
Inventor: LANG ARMIN
IPC: F16K31/383
Filed: 1975-01-08
Abstract: The main piston (8) is bored at its tuner end to receive a helical spring and at its outer end to receive a stepped diameter secondary piston (9), which is connected by a radial orifice (12) to the outlet (5). The secondary piston has interconnected axial (10) and radial (13) orifices. Normally spring pressure holds the secondary piston against a stop in the primary piston but as the pressure increases, the secondary piston is moved against this spring pressure until a step (11) stops it when its radial openings vents the spring chamber to the outlet. The effect of the pressure on the primary piston face (3) forces the piston assembly deeper into the bore and opens the main fluid passage.

Inventor: WONG JAMES
IPC: H01L39/06
Filed: 1975-02-07
Abstract: This multi-cored superconductor uses a wire or bar matrix of a first, normally-conducting matl. (I) contg. numerous strands or cores. Each core has a skin of a superconducting intermetallic cpd. with type II beta-tungsten structure, on a substrate of a second, normally-conducting matl.

(II) the bronze, or vice versa, whereas the intermetallic cpd. may be Nb3Sn on a tin-bronze coated with Nb, or V3Ga on a gallium-bronze coated with vanadium. The process is used for the mfr. of multi-cored wire for electromagnets and other current carrying applications. High electric stability when using high fields and high currents; the diffusion heat-treatment can be carried out continuously in 2 hrs. max. with no need to heat coils of wire.

Title: Air duct sound attenuator - with inlet pick-up processed to feed back cancelling sound at outlet of duct
Inventor: LAWSON-TANCRED HENRY
IPC: G10K11/178
Filed: 1975-02-21
Abstract: The method is for reducing sound propagation along a channel, for example, in the suppression of fan noise in air ducts, and is of low cost and high efficiency at the lower frequencies. The sound is picked up at a point of the sound path and fed to a parallel path as a signal which is processed. At a point nearer the quiet area to be protected, the processed sound is fed back in the form of a compensation signal which reduces the total sound to nearly zero. The processor may take the form of filters with a suitable phase shift for each component frequency, or delay elements with an equal delay for all frequencies.

Title: Yarn creel breakage monitor - has a monitor housing coupled to eyelet bar at each level to show location of yarn breakage
Inventor: THEISEN HANS
IPC: D02H1/00
Filed: 1975-10-04
Abstract: Appts. is for monitoring and registering a yarn breakage, as yarns are drawn from their bobbins in a creel for a loom or a warping machine. The yarns are drawn off from the layers of bobbins through eyelets, the yarn monitor being supported by each yarn so that, on a breakage, the monitor drops and registers the fault. The yarn monitor and 2 eyelet bars of a bobbin layer incorporate a coupling and counter coupling. The design gives a simple construction for the yarn breakage monitor system and also allows rapid and easy identification of the location of the breakage.

Title: Lavatory basin mixer valve - has built in stop valve for use where instantaneous water heater provides hot water supply
Inventor: GRUBER WALTER
IPC: G05D7/01
Filed: 1975-12-22
Abstract: A mixer valve is installed underneath the lavatory basin, where there is little room for a stop valve. Thus enables repairs to be carried out without cutting off the water supply to the other outlets. The device takes the form of a plug of elastic material which can be moved in from the side to block the water inlet. The elastic material is put on the end of a recessed screw, which is turned by screwdriver. Work can thus be effected without disturbing other units.

Title: Watertight one size bathing cap - has inflatable tube round brim with mouth piece for inflation in position on head
Inventor: VALDIVIA LUDENA MARIANO
IPC: A42B1/12
Filed: 1975-12-30
Abstract: The bathing cap has an inflatable tube fitted round its inner edge. The tube is provided with a hole and stopper to allow it to be inflated by any desired amount. The addition of this tube enables the cap to be fitted more closely to the head, increasing its water tightness. The tube opening can also be provided with a mouth piece to allow the tube to be inflated while the cap is on the head. The increased water-tightness of the cap ensures that the wearer's hair remains dry, and the cap does not destroy the hair style. A single cap size can be used to fit a range of head sizes. At the same time the edge round the cap when deflated is larger and therefore the cap is easier to put on.

Title: Voltage memory for maintaining voltage signal delivery - has signal frequency and phase in fixed relation to input mains voltage
Inventor: EGLI ERNST
IPC: H02H3/26
Filed: 1976-01-26
Abstract: A network protection system employs a voltage memory to continue an input signal for a voltage so that it is maintained for a certain time after an abrupt change of mains voltage. A control circuit (20) comprises a phase comparator (21), anRC low-pass filter (22) and a voltage controlled oscillator (23) with an oscillating capacitor (C1) and a blocking signal input (5). The switching path of an electronic switch (25) is inserted between phase comparator (21) and low-pass filter (22). When the switch (25) is conducting, the control circuit is blocked, and when the switch is blocked the VCO (23) freely oscillates at a frequency corresponding to the low-pass filter (22) charging voltage. The VCO blocking input (5) is connected to a starting pulse generator (29), so that each starting pulse unblocks the VCO (3).

Title: Table top cigarette lighter with piezoelectric igniter - has pivoted non-tilting and non-jamming actuating key with rotating arms
Inventor: BOEHME HEINZ GERHARD DIPL ING
IPC: F23Q2/28
Filed: 1976-02-02
Abstract: The table top cigarette lighter has gas tank which also encloses the piezoelectric igniter. The latter is operated by an impact mechanism which also actuates the burner valve. The igniter unit, igniting electrodes and burner are arranged side by side in a common vertical plane.
