Title: Apparatus for separating materials of different consistency
IPC: B29C48/694
Filed: 1982-10-21
Abstract: For separating material mixtures, in particular of thermoplastics mixed with solids, the plasticised material to be separated is fed to the interior (23) of a hollow-cylindrical filter element (7). The filtered material is transported away via channels (39, 41, 43) from the outside of the filter element (7). The filter residue is conveyed by scrapers (19) of a rotatably driven scraper shaft (17) to an outlet provided with a retaining device (47). The filter element (7) comprises a single piece of material having a smooth inner jacket and a circumferentially ribbed outer jacket. The filter openings (37) are made by a laser or electron beam machining process in the bottoms of the circumferential grooves (33) formed between the circumferential ribs (35). The resiliently prestressed scrapers (19) are supported via the ribs (35) on the housing (9). <IMAGE>

Title: Device for the interpolation of an abruptly changing voltage
Inventor: HERTLEIN KURT DIPL ING
IPC: G11C27/02
Filed: 1982-12-11
Abstract: A device for the interpolation of a voltage which can change abruptly in synchronism with the signals of a clock signal sequence is specified, with which device no inadmissibly high accelerations or forces or oscillations occur in downstream systems, for which the output voltage serves as a reference variable, manipulated variable etc. This is achieved by the difference between the voltage (x(t)) and the output voltage (x'(t)) of an integrator (3) being written to a memory (1) when a clock signal (CLK) occurs and stored there until the occurrence of the next clock signal, and the respectively stored value is integrated by an integration coefficient (KI) in the integrator (3), the factor (KI) being chosen such that the output signal of the integrator (3) changes within the period (TCLK) of the clock signals precisely by the amount of the stored voltage difference (x(t) - x'(t)). <IMAGE>

Patent DE-3305823-A1 (DE)
Title: Fitted protective sealing lip to prevent damage to tyre beads
Inventor: FABRITZ PETER
IPC: B60C15/024
Filed: 1983-02-19
Abstract: The fitted protective sealing lip has the function of sealing the damage which in most cases is almost invisible even at the fitting stage and is often also unavoidable. In this regard it is important to know that the bead zone, which, for reasons including static considerations, is necessarily very strong and rigid in construction, contains the end and start zone of the carcass layer in its core. If during fitting hair cracks occur in the area of the bead inner zone (part of the tyre within the rim/rim flange) on account of an incorrectly placed fitting tool, these hair cracks are enlarged on account of the widely different effects. These effects may be low air pressure, heavy loading but also a certain existing storage (ageing of the rubber tyre). Since at present all tyres are pressurised with moist, that is to say water-containing, air (nitrogen tests are underway for petrol vehicles etc.), this water tries to move outwards, partly caused by centrifugal forces. In this case the water (air humidity) in the hair cracks migrates within the bead rubber to the reverse layer, to the carcass reverse layer to the bead core and along the carcass layer. The possibility of migration comes from the fact that the steel fabrics are only covered (although at high temperature) with tread strips, but cannot become homogenous with the rubber. Air zones therefore exist in the entire tyre, which air zones .... under certain circumstances in total failure of the tyre in the case of the above-described damage ... Original abstract incomplete.
Patent DE-3308817-A1 (DE)
Title: Integral attachment of tension-loaded components with direct force transmission
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/18
Filed: 1983-03-12
Abstract: The invention relates to an integral connection of two components, preferably tension-loaded fittings with thin-walled metal plates, e.g. the bodywork metal in motor vehicles, in which the force flow takes place from one part into the other part positively and directly due to corresponding design of the parts, and the positive-fitting position of the two parts being guaranteed by a connecting element which is small and easy to handle, or by deformation of corresponding attachment tabs formed by the metal plate itself, without using additional connecting elements. By avoiding force concentrations on one point, as usually occur, for example, in force transmission by screws, the use of additional reinforcing metal plates can be avoided. A reduction in weight and costs thus results. Due to the ease of assembly resulting from the design of the parts to be connected, a further cost saving results due to a reduction in the production time. <IMAGE>

Patent DE-3313260-A1 (DE)
Title: Sensor
IPC: G01L19/14
Filed: 1983-04-13
Abstract: The invention relates to a device for measuring pressures, in particular high pressures, and temperatures in a hydraulic or pneumatic system, preferably with the aid of a piezoresistive pressure measuring cell and an electronic circuit which is integrated in a housing to form a unit. The latter has a helical housing which is divided into a pressure chamber, which contains the pressure sensor and is separated from the pressure system by a pressure-transmitting diaphragm, and a zero-pressure chamber, which is connected by means of electrical contacts and contains the associated electronic circuit, the pressure chamber containing a temperature sensor which is likewise connected to the electronic circuit, and the temperature prevailing in the pressure chamber and thus in the system being continuously measurable and the measured value simultaneously being evaluatable for the purpose of temperature compensation of the pressure sensor. The electronic circuit is constructed in the zero-pressure chamber of the helical housing as a hybrid amplifier which serves to amplify weak output signals of the pressure sensor and temperature sensor, and at the same time has a temperature compensation circuit for correcting the characteristic of the pressure sensor. The invention further relates to a method for measuring pressures, in particular high pressures, in which the temperature values measured continuously by the temperature sensor ...

Title: Method for regenerating a soot burn-off filter for cleaning the exhaust gases of diesel engines
Inventor: ABTHOFF JOERG DR ING
IPC: F02B3/06
Filed: 1983-08-04
Abstract: A description is given of a method for the accelerated regeneration of a soot burn-off filter for cleaning the exhaust gases of diesel engines. The method consists in that the speed of the gases flowing through the filter is lowered during the regeneration phase. A shortening of the regeneration phase in comparison with the conventional methods is thereby achieved. The speed of the gas is preferably lowered by taking some of the exhaust gases past the filter by means of a bypass line during the regeneration phase. The shortening of the regeneration phase makes it possible to perform complete regeneration of the filter more frequently.
