Patent DE-2723507-A1 (DE)
Title: Active vibration damper between mass and spring - has pressure regulator without reference mass stabilising tractor seats
Inventor: FISCHER JUERGEN DIPL ING
IPC: B60N2/52
Filed: 1977-05-25
Abstract: The active vibration damper is connected between a mass and a spring. The damper has a hydraulic piston and cylinder system connected to a pressurised oil source. The damper has a regulating edge following the relative movement between the mass and spring. This damper is used with hydraulic adjusting signal and the damper can be used for stabilising seats of agricultural tractors. The damper does not utilise a reference mass and compares the pressure directly with the mass to be stabilised. The hydraulic pressure within the damper is used as measuring signal. A pressure regulator keeps this signal constant. The control edges are arranged between the working chamber and either the oil storage or pressurised oil source.

Title: Flanged clamping system for grinding wheels - ensures uniform wheel clamping between rigid and flexible flanges by stops
Inventor: SALJE ERNST PROF DR ING
IPC: B24D5/16
Filed: 1977-07-16
Abstract: The clamping arrangement for grinding wheels has bolted clamping flange and ring. Clamping forces are accurately controlled and are uniformly transmitted between both flange parts. The clamping arrangement is of relatively simple design. One of the two flange parts (1, 2) is made relatively rigid. The other flange part or at least a spacer placed between the second flange part and the grinding wheel (3) has flexible characteristics. between the flange parts are arranged, in specified positions, stop faces (13, 14). The latter form clamping displacement stops when the flange parts are clamped. The holding flange part (1) is rigid and the counter flange (2) is flexible. The stop faces are arranged directly on the flange parts or on the elements connected to these flange parts.

Title: Plastics drum for storing fluids, with a pressure equalising lid - includes permeable plastics membrane which permits the passage of gas but not liquid
Inventor: WENGENROTH HANS EGON
IPC: B65D51/16
Filed: 1977-08-31
Abstract: Plastic drums for storing and transporting liquids are sealed by means of a plastic membrane between the lid of the drum and the contents. The perforated membrane is permeable to air and impermeable to water and is clamped between the body and the lid of the drum so that an air space is present between the liq. and the membrane and between membrane and lid. Where the membrane passes between the drum and the lid, folds are created which do not permit the passage of fluid from the inside of the drum beneath the membrane but allow has to pass into or out of the space between membrane and lid. The space between fluid and drum lid may be divided by the membrane so that the greater space is either above or below the membrane. Pref. the membrane consists of a plastic cylinder or hose with a dia. greater than that of the drum (by a factor of 1.01 to 1.3 times the drum dia.) and a depth of between 0.1 and 0.25 m. The membrane consists then of that part of the cylinder wall trapped inside the drum and the end sheet of the cylinder.

Title: Computerised electronic flash for photography - assesses reflected light and extinguishes flash in relation to independently set film speed and aperture settings
Inventor: UCHIYAMA TAKASHI
IPC: G03B7/16
Filed: 1977-11-29
Abstract: The computerised electronic flash, for photographic use, not only terminates flash exposure according to the refected light from the subject but adjusts flash duration according to film speed and aperture setting. The flash is intended for automatic cameras, esp. those with shutter priority, and requires input information from the camera such as film speed, aperture setting, so that correct flash exposure can be given. Connection of flash to camera will be through a hot shoe (11) so that jack connections (T1, T2, T3, T4) can carry the variety of information about camera settings required by the flash during flash exposure. Sensitivity of the sensor circuit (137) is tuned by aperture setting (134) information to capacitors (135) and film speed (133) to a potentiometer (144).

Title: Sink, wash-basin or bath outflow fitting - has electromagnet holding plug closure, actuator with spring or weight for release
Inventor: VIEGENER WALTER
IPC: E03C1/242
Filed: 1978-03-25
Abstract: The valve housing contains a raisable and lowerable stop plug with an actuator in the discharge fitting on a wash-basin, sink, bath or other sanitary appliance. The actuator is fixable in the outlet position corresponding to the plug's (3) closure position, by a low-voltage-supplied electromagnet on the valve housing (4, 5). The magnet is disconnectable by one or two probes (20) at the max. filling level of the space for water. A spring weight or other element serves to move the activating device into the end position for opening the plug. This obviates any need for a separate overflow.

Title: Three section telescopic hydraulic ram - has block inside outer cylinder with two valves operated by pressure differences each side
Inventor: HEINZE HARRI ING GRAD
IPC: E21D15/44
Filed: 1978-03-25
Abstract: The telescopic hydraulic ram for mining has an outer cylinder (2), a middle cylinder (3) and an inner cylinder (4). The latter has a helical spring (26) inside, connecting it to a block (11) which can slide inside the outer cylinder and which has a stepped top to support the bottom of the middle cylinder. Incorporated in this block are two valves (14, 15) communicating with the space (16) under the innder cylinder. The first valve has a pin (20) protruding from the base of the block which when depressed, pushes a ball inside against a spring to open the valve. When closed, it is operated by a difference in pressure between chamber (12) for the middle cylinder and the inner space (16). The second valve (15) is also operated by a difference in pressure between these spaces, when the plunger is forced downwards against spring force.

Title: Gasification of solid fuels in molten slag bath - giving synthesis or reducing gas mixts. of improved compsn.
Inventor: PFEIFFER ROLAND DIPL PHYS DR
IPC: C10J3/57
Filed: 1978-03-25
Abstract: Prodn. of cracking gas (CO/H2) mixt. from fuels, e.g. powdered coal, is effected by reaction with a gasifying medium, e.g. O2, in a high temp. alag bath through which the reactants flow. Used as synthesis or reducing gas mixts., e.g. for iron are reduction. Compared with the known process in which the reactants are blown tangentially onto a rotating slag bath, passage through the slag gives a reduction in CO2 content, e.g. from 14% to nil, and in H2S content, e.g. from 0.5% to 85 ppm. In the product gas.

Inventor: KLEIN HOWARD PAUL
IPC: C08G18/40
Filed: 1978-06-10
Abstract: A rigid polyurethane foam showing resistance to heat distortion is obtd. by reacting an organic polyisocyanate and a polyol mixt. In the presence of a blowing agent and a catalyst. The polyol comprises 5-85 wt. % of an allyl alcohol styrene copolymer and 15-95 wt. % polyether polyol of hydroxyl no. 200-800.

Title: Automatic equalisation of transmission time in digital system - controls phase of received signal by varying filter characteristic
Inventor: LUDWIG VOLKER DIPL ING
IPC: H04L25/03
Filed: 1978-07-25
Abstract: A date source (DQ) controlled by a clock (TG1), delivers digital signals (A) to a transmitter (SE). The resultant base band signal (B) passes along a transmission line (UST) to a receiver (EM). A discriminator signal (E) with a locally-generated timing signal (T2) form a measurement signal (G). This sets the all-pass filter (AP), using an FET, to control the phase of the received signal (B2). Equalisation of transmission time is automatically achieved, so that the receiver may be easily used on various transmission lines in the frequency range 0 to 150 kHz.

Title: Warp-knitted outerwear stretch fabric - comprising elastic mesh with additional tricot yarns to prevent excessive elasticity
IPC: D04B21/18
Filed: 1979-05-12
Abstract: An elastic warp-knitted fabric has a warp of inelastic threads forming chain stitch along a single wale for three courses, which is then offset by one wale to form three chain stitches in the neighbouring wale, before returning to the first wale. A second warp of elastic threads is inlaid with the first set of threads and laps in a similar manner, around the same needle for three courses, then shogging sideways in step with the first set for another three courses, and finally returning to the first wale. A third warp comprising inelastic, pref. polyamide threads, executes a tricot pattern, counter-lapping the other two warps. The tricot threads reduce the elasticity and increase the stability of the fabric, without destroying the open-pored structure which gives good wearing properties.
