Title: Process for the preparation of flowable pastes from a plurality of polyvinyl chloride polymers which cannot be made into pastes individually
Inventor: BOGUSLAWSKI ZBIGNIEW DR ING
IPC: C08J3/12
Filed: 1981-12-18
Abstract: Process for the preparation of flowable pastes from a plurality of polyvinyl chloride polymers which cannot be made into pastes individually, by gelling PVC polymer under mechanical flexing with addition of a plasticiser or plasticiser mixture. First, a mixture of various polymers having a spherical, compact particle structure is prepared in a classification which gives a spherical packing which fills at least 50% of the space, and the mixture is subsequently initially gelled by means of the plasticiser or plasticiser mixture in such a manner that only microgelling of the glassy surface takes place.

Title: Angular velocity sensor
Inventor: MIYASAKA TAKAO
IPC: H02K21/22
Filed: 1981-12-22
Abstract: The angular velocity sensor described has a magnetic circuit and a plurality of sensor coils arranged radially with respect to the torque shaft of a rotor. In this arrangement, each sensor coil is wound around a radial projection of a circular disc consisting of magnetic material, so that the axes of the sensor coils are aligned normal or perpendicular to the torque shaft. The sensor coils are, furthermore, connected electrically to one another in series in such a way that an interference voltage induced in one of the coils due to an external magnetic flux has a polarity opposed to that of the interference voltage which is induced in a further coil arranged opposite with respect to the torque shaft. The electrical connection of the sensor coils extends in a prescribed circular direction, while a lead-in wire connected to the last coil of the series circuit is guided in a circular direction which is opposed to the direction of the series circuit.

Title: Device for connecting the front wheel fork to the motor bike frame absolutely without play by means of a novel bearing nut
Inventor: SCHWARZ EMIL
IPC: B62K21/00
Filed: 1982-01-26
Abstract: The bearing nut produces a play-free connection between the frame and front wheel fork. In the conventional bearing of the front wheel fork, a play of upto 0.15 mm is present on the upper control head bearing. This play continues as far as the point of contact of the tyre on the road and is increased depending on the type of motor bike by 6 to 10 times, that is to say upto 1.5 mm. The play at the upper control head bearing is eliminated by the bearing nut, that is to say 0.0 mm; there is also no movement at the point of contact of the tyre.

Title: Method and device for improving the combustion of a mixture in an internal combustion engine
Inventor: AHLGRIMM HERBERT
IPC: F02M26/19
Filed: 1982-10-11
Abstract: In the case of a method for improving the combustion of a mixture consisting of a fuel fraction and an air fraction which flows at a predetermined rate towards a combustion chamber of an internal combustion engine, the mixture is first accelerated from this predetermined rate of flow before entering the combustion chamber until the fuel fraction vaporises due to a resulting pressure drop in the mixture and then slowed back to the predetermined rate of flow. A cross-sectional constriction increasing the rate of the flowing mixture is provided in front of the combustion chamber, between which constriction and the inlet a smoothing section is arranged, which again reduces the rate of flow of the mixture.

Abstract: The invention relates to a plate, in particular an extruded or continuously cast plate, which can be connected to neighbouring plates of the same type by cold-workable edge portions. The intention is to provide a plate of this type which, for the purpose of connection to neighbouring plates, necessitates a relatively simple cross-sectional form of the plates, is insensitive to tolerances, ensures a high degree of accuracy of the mutual position of the plates to be connected, can, furthermore, be fitted together easily with neighbouring plates, and, therewith, can achieve a high degree of gas-tightness and water-tightness and also a high degree of shear strength in the plate plane. For this purpose, the invention provides the combination of features such that one longitudinal or transverse edge of the plate (1, 2) is provided with a cold-workable connecting element (7, 8) and, parallel thereto and in the vicinity thereof, with a part (3) of a guide and retaining element (3, 11), and the second longitudinal or transverse edge has a die part (13), corresponding to the cold-workable element (7, 8), and a second part (11) which is assigned to one part (3) of the guide and retaining element (3, 11). <IMAGE>

Patent DE-3320835-A1 (DE)
Title: Multi-position drive
Inventor: FUOSS DIETER
IPC: F02B75/02
Filed: 1983-06-09
Abstract: The multi-position drive has applications in internal combustion engines, especially in four-stroke spark ignition engines with valve control, which are largely used in passenger vehicles. In the case of these four-stroke engines the aim is to minimise fuel consumption whilst maximising the power output. This demand would be met if the fuel-air mixture present in the cylinder were to remain there up to the completion of combustion. In the case of the present valve control with fixed control times this is not ensured since these control times are ideal only for a small engine speed range and otherwise the fuel-air mixture either escapes unused through the exhaust system or is forced back into the intake port. The multi-position drive solves this problem in that it rotates the inlet and the outlet camshaft in relation to the crankshaft, thereby adjusting the control times ideally to the speed of the engine. The rotation of the camshafts is performed by an electronically controlled stepping motor and a special torsion segment.

Title: Process and production of light concrete bricks, breeze blocks and hollow breeze blocks from ceramicised bituminous coal dressing wastes
IPC: C04B28/02
Filed: 1983-07-23
Abstract: The raw material base for the production of light concrete bricks, breeze blocks and hollow breeze blocks is substantially widened by a process in which the fractions rich in argillaceous schist or clay, of a gangue material having a high content of expansion-promoting constituents which can be expelled, preferably carbon, are subjected to a controlled thermal treatment, that is to say are ceramicised. This starting gangue material has expediently been classified previously at 0 to 12.5 (16) mm and is then treated with water, with addition of binders, preferably cement, and then formed into bricks and subsequently or simultaneously hardened. After the ceramicisation, the gangue material used and previously classified has a pore volume of more than 10%, so that it can be used as a fully equivalent substitute for natural pumice, in particular if two particle size bands from 0 to 4 mm and 4 to 12.5 mm are classified and mixed with one another in a ratio of preferably 1:3 and then further processed correspondingly. The bricks thus produced meet the conditions of the appropriate DIN standards and, with respect to both weight and strength properties, are very suitable for construction in the form of light concrete bricks, breeze blocks and hollow breeze blocks and also as panels.

Abstract: In a sensing or measuring arrangement for determining the position or dimensions of a test object, the sensing arrangement housing is fastened to a receiving element for the installation of the sensing housing onto a tool receptacle of a spindle of a machine tool. A voltage source is included in the sensing housing to power a measuring signal transmitting system. In addition, a switching arrangement is included for switching the voltage source from a standby mode of operation characterized by low current consumption to a measurement mode of operation in order to increase the life of the voltage source. This switching arrangement is responsive to an expansion measuring strip which detects an axial elongation of the receiving element in the tool receptacle. In the disclosed embodiment the expansion measuring strip is fastened to an inner surface of the receiving element which is subject to axial elongation when the receiving element is installed in place in the spindle of the machine tool.
