Patent DE-3239669-A1 (DE)
Inventor: KLOETZER ERHARD DIPL CHEM DR
IPC: C04B11/02
Filed: 1982-10-27
Abstract: 1. A continuous process for recovering industrially utilizable gypsum from industrial waste gypsum by partial or complete hydrothermic conversion of waste gypsum into calcium sulphate-alpha-hemihydrate in a tube reactor using steam at temperatures of between 130 and 180 C, characterized in that, in order to make the crystallization uniform and to avoid reverse sedimentation and interruptions in the process, hot steam is passed at least once vertically upwards in parallel flow with the gypsum suspension with a flow velocity of between 5 and 20 m/min and immediately afterwards vertically downwards from above, and the degree of conversion is controlled by dwell periods of between 3 and 20 min.

Title: Silicate of high magnetisability, and process for producing it
Inventor: NOELLER RENATE
IPC: H01F1/37
Filed: 1982-10-28
Abstract: The incorporation Fe<3+> ions into Ca silicates (diopside, gehlenite) at temperatures of 1443 K is effected via the substitution of ions of different oxidation level and at differently coordinated lattice positions, which leads to considerable lattice imperfections. These result in special magnetic properties of these silicates. These silicates are prepared from CaCO3, MgCO3, SiO2 gel and  alpha -Fe2O3. The substances are mixed, pressed to give a pellet and, after slow heating-up in the course of 6 hours, tempered for 24 hours at 1443 K.

Title: Ski lift towing cable connection with directional cams
Inventor: FUCHS FRANZ
IPC: B61B11/00
Filed: 1982-11-24
Abstract: The invention relates to a ski lift towing cable connection with directional cams, which connection connects the towing cable to the towing bar on ski lift towing slopes. In order to avoid the known towing cable wear via the directional cam, according to the invention the connection of the towing cable to the directional cam of the towing bar is made by means of a chain-like connecting element and an eyelet screw. The eyelet screw is rotatably arranged here in the directional cam and forms together with the connecting element a rotatable joint. By means of this connection, the swinging and dangling movements of the towing bar which occur when the towing cable is being drawn in take place in the joint connection in a manner which spares the cable. The directional cam itself is designed in such a way that after the towing cable is drawn in it locks to the housing contour counter to the direction of travel. <IMAGE>

Title: Method for mixture preparation in a spark ignition engine and spark ignition engine for performing the method
Inventor: SIEBENSOHN GUENTER
IPC: F02M31/18
Filed: 1982-12-24
Abstract: In the mixture preparation method the fuel, fed to a mixing chamber by means of an injection nozzle, is mixed with aspirated air from the engine. In the spray area of the injection nozzle the fuel is vaporised by heating, thereby achieving a reduction of the CO content of the engine exhaust gas. In a spark ignition engine with carburettor, a heating element (10) is arranged in the mixing chamber (4) in the area of the outlet orifice of the mixing pipe (2). As in the engine with carburettor, a reduction of the CO content of the exhaust gas is also achieved in an engine with injection pump by arrangement of the heating element in direct proximity, that is in the spray area of the injection nozzle (Fig. 1). <IMAGE>

Title: Carpet and process for producing it
Inventor: ALBRECHT JEAN-MARIE
IPC: D04G3/02
Filed: 1983-08-12
Abstract: The invention relates to a carpet and to a process for producing it, the carpet (1) consisting of a support composed of knitting wool (3) and of a sheet-like carrier material (2) composed of soft woven cloth, especially a cottonised flax, with warp (4) and weft (5) yarns. The knitting-wool yarn (3) loops round one or preferably a plurality of warp (4) and weft (5) yarns in one yarn direction of the woven cloth (2). In the yarn direction of the woven cloth (2) orthogonal to this, each adjacent warp (4) and weft (5) yarn is looped round, so that a sheet-like row composed of support material (3) is obtained. In the finished carpet, one row lies against the other, so that the entire surface of the carrier material (2) is covered. What is achieved is an especially soft and smooth carpet without distortions, which, on account of the simple production, the favourable material price, a variable size selection and its clearly expressed patterning, is extremely suitable for making at home for hobby purposes. <IMAGE>

Patent DE-3342057-A1 (DE)
Title: Linearity control
Inventor: KUNZ MANFRED
IPC: G01S7/40
Filed: 1983-11-22
Abstract: For FM linearity control in mobile radar devices which operate using the linear FM-CW method, an extremely linear modulation characteristic is produced by means of a phase-locked loop in that the delay line, which simulates a target in terms of its transit time, is designed in the form of an optical fibre. Part of the transmission power of the linear FM-CW-modulated transmission oscillator is fed directly or by way of a step-down conversion to a laser diode as a modulation signal, is delayed via the optical fibre and is transformed via a light detector diode back into the original frequency range. After the signal delayed by the optical fibre has been mixed with the undelayed signal, and after the subsequent comparison of the differential frequency fDif occurring at the output of the mixer with a crystal-stabilised reference frequency which is phase-locked in relation to the evaluation time TA, the phase comparator supplies at its output a voltage signal which provides a direct measure for the deviation of the FM from its linearity, if the reference frequency is selected in such a way that it coincides with FDif at any time within the evaluation time TA. This error correction signal is used to control the linearity of the FM. <IMAGE>

Patent DE-3408305-A1 (DE)
Title: Brake system for motor vehicles
Inventor: PROHASKA HANS
IPC: B60T8/28
Filed: 1984-03-07
Abstract: A brake system for motor vehicles is described, in which the brake pressure is controlled as a function of the movements of the vehicle body. In a preferred embodiment, the pitch movement of the vehicle body in the event of drastic braking is detected by means of a sensor. As a function of the output signal of this sensor, the brake pressure is periodically converted from a predetermined maximum value to a predetermined minimum value. At the same time, the brake pressure maximum value can be adjusted as a function of a previously performed measurement of the coefficient of friction between wheel and road surface.
Patent DE-3410071-A1 (DE)
Title: Hydraulic system
Inventor: ALTMANN UWE
IPC: F15B21/04
Filed: 1984-03-20
Abstract: The hydraulic system has an adjustable pump (10) which supplies two hydraulic circuits connected in parallel, specifically a primary circuit (A) and a secondary circuit (B), with pressure medium via a priority valve (15). The distribution of the pressure medium currents for the two circuits is performed via an adjustable restriction valve (21). Arranged between the priority valve (15) and load (37) of the secondary circuit is a control valve (32) which can be influenced by an element (33) which is made from a dilatable material and bathed by a cooling liquid flowing in a line (34). Arranged in this line is a heat exchanger (35) through which a ventilator driven by the hydraulic motor (37) of the secondary circuit blows cooling air. When the cooling liquid has reached an upper limiting temperature value, the element (33) made from dilatable material sets the control valve (32) in such a way that the hydraulic motor (37) is supplied a larger quantity of liquid. The pressures in the two circuits are propagated via control lines (42) to the flow control valve (48), by means of which the pump (10) is set such that it supplies precisely the quantity of pressure medium required at the hydraulic motors. This results in an energy-saving operation of the hydraulic system and a continuous temperature-dependent variation in the rotational speed of the ventilator. <IMAGE>
