Inventor: LAUT BERNHARD
IPC: C09J1/02
Filed: 1981-03-20
Abstract: An adhesive composition based upon an aqueous solution of alkali metal silicate with a content of powdered inorganic filler, having good storage stability, which comprises an aqueous alkali metal silicate solution containing: (a) from 10% to 40% by weight of at least one powdered inorganic filler, (b) a suspension effective amount of at least one zinc soap of a fatty acid having from 12 to 22 carbon atoms and (c) from 0 to about 24% by weight of a 50% by weight stable, aqueous dispersion of an alkali-resistant organic polymer, based on the weight of the total composition. Preferably zinc stearate in amounts of from 1% to 5% by weight are added to the adhesives containing powdered inorganic fillers and optionally organic additives on a base of aqueous water glass solutions, to prevent separation phenomena. Sodium and/or potassium silicate solutions can be used, the sodium silicate solution being preferably present in the ratio by weight of 3.3 to 3.9:1 for SiO2/Na2O, with a solids content of 38% to 28% by weight and the potassium silicate solution at a ratio by weight of 2 to 2.6:1 for SiO2/K2O, with a solids content of 40% to 29% by weight. The inorganic filler is preferably powdered crystalline calcium carbonate in the form of metamorphous calcite with particle sizes of up to 25  mu m.

Title: High-value substitute detonating gas for internal combustion engines and heaters
Inventor: BROSS RAINER HENNING
IPC: C25B3/00
Filed: 1981-03-21
Abstract: Organic wastes of any type (human excrement, wastes) from domestic refuse etc. are ground and anaerobic bacteria are added. The substances excreted by the bacteria decompose the irrigated solution which is charged into a device identical to in principle, even though enlarged, a car battery. However, this is polarised the other way around. Selenium cells are to supply the energy for this, since, because of the danger of ignition, the voltage must in any case remain very low. A detonating gas of high mechanical value results. Since we do not have to apply any type of additional energy, the gas is formed virtually "by itself", it is a very inexpensive process.

Title: Tuning device for digital transmitter selection in broadcast receivers, in particular in VHF receivers
Inventor: SEIBOLD PETER DIPL ING
IPC: H03L7/181
Filed: 1981-07-02
Abstract: A tuning device is indicated for digital transmitter selection in broadcast receivers, in particular in VHF receivers which enables a very fast and therefore inaudible changeover between two transmitters. The tuning device has a digital counter which measures the oscillator frequency (actual frequency), an ideal value generator for digital input of the receive frequency (ideal frequency) of a required transmitter, a comparator for the actual-ideal comparison and a device for generating an oscillator tuning voltage depending on the output signal of the comparator. According to the invention, the latter has a successive approximation register whose data input is connected to the output of the comparator and whose parallel outputs are connected to a digital-analog converter. Successive outputs of the register are seized in succession with an output signal, the output signal of the previous output being retained or cancelled before the respective next output is seized depending on the output signal of the comparator. The output signal of the comparator represents sign information for the existing frequency deviation. The analog output voltage of the digital-analog converter forms the control voltage for the oscillator of the broadcast receiver.

Title: Brake cylinder, in particular a combined service-brake and spring-brake cylinder
Inventor: SCHUSTER WALDEMAR
IPC: B60T17/08
Filed: 1981-11-03
Abstract: In a combination cylinder comprising a service-brake cylinder and spring-brake cylinder, in particular for motor vehicles, a common housing, preferably comprising a deep-drawn sheet-metal part, is provided, and it is thereby possible to limit the structurally determined radius of action of the brake cylinder to a minimum.

Patent DE-3147297-A1 (DE)
Title: Control device for regulating the pulling force of a soil-cultivating appliance articulated on a vehicle
Inventor: STEPRATH WERNER ING GRAD
IPC: A01B63/112
Filed: 1981-11-28
Abstract: What is proposed is a control device (10) for regulating the pulling force of a plough (13) articulated on a tractor, of which the hydromechanical transducers (52, 37) measuring the forces in the lower links (14, 15) work without an elastic member. The transducers (52, 37) assigned to each lower link (14, 15) and loaded mechanically via intermediate levers (16, 17) are located in parallel branches (33, 32) of a hydraulic bridge connection serving as a control circuit for a directional regulating valve (23). The pressure between the two resistors (52, 53) of one bridge branch (33) is applied to the transducer (37) of the other bridge branch (32), with the result that the intermediate pressure in the other bridge branch (32) is dependent on the sum of the lower-link forces and controls the directional regulating valve (23). The hydraulic force measurement without a measuring spring leads to a low-vibration mode of operation of the control device (10), this being further assisted by the direct signal processing in a hydraulic bridge connection and allowing the use of simple constructional elements. <IMAGE>

IPC: F25B41/06
Filed: 1981-12-23
Abstract: The invention relates to a pressure release device for refrigerating medium circuits, in which the refrigerating medium is alternately liquefied by compression and evaporated by pressure release. It relates in particular to the refrigerating medium circuits of heat pumps and the like and aims to produce an expansion device which is not only simple and economical in construction but in particular has a wide range of use with regard to the condensation temperatures, the evaporation temperatures and the temperature differences between these temperatures and the associated pressures, and independence from the selection of the refrigerating medium with constant accurate control of the expansion, and makes no adjustment or readjustment necessary in the entire working range. According to the invention, the pressure release device is to this end to be designed as a thermodynamic steam trap, connected parallel to which there is possibly a further pressure release member which is preferably in the form of a capillary tube. <IMAGE>

Abstract: The invention relates to a cyanide- and cyanate-free agent for salt bath carbonitriding in the temperature range from 750 to 850 DEG C to produce carbonitride coatings of known structure on steel materials. Labour time and energy costs and material costs are saved during the preparation of this agent according to the invention.

The object of the invention is to find the composition of a cyanide-and cyanate-free agent which acts as carbonitriding salt and at the same time can be used for regeneration. This is ensured by a salt mixture composed of     40-50% of dicyandiamide   20-30% of urea   5-15% of alkali metal carbonate   10-20% of alkali metal chloride   and 2-10% of flake graphite as carbonising support. i
