Patent DE-3225002-A1 (DE)
Title: Clearing device on scraper arms for clearing piles of bulk goods
Inventor: AMELUNG KURT
IPC: B65G65/06
Filed: 1982-07-03
Abstract: In scraper arms with conventional clearing devices, the scraper plates are held on their carrier immovably about the longitudinal axis of the carrier in a vertical plane. With all excavation methods that require a sidewards movement of the scraper arm and its scraper plates into the material, the scraper plates undergo unilateral loads and a non-uniform wear of their cutting edge, with the result that bearings and guides of the scraper plate carrier are also subjected to unilateral loads. A new scraper plate holder is proposed, which substantially eliminates the harmful unilaterial loads. It is characterised by the fact that the scraper plates are disposed so as to be pivotable about an axis extending in the direction of movement of their carrier. Here the scraper plate carrier may be either of stiff or flexible design and holders are provided at intervals on said carrier, to which the scraper plates are fastened, in the case of a flexible carrier the longitudinal axis of said carrier forming the pivot axis of the scraper plates, in the case of a rigid carrier on the other hand each holder having an axis that is axially parallel to the carrier, which axis receives the scraper plate allocated to it and forms its pivot axis.

Title: Circuit arrangement for electrically separately driving at least one power transistor
Inventor: GABRIEL RUPPRECHT DIPL ING
IPC: H03K17/56
Filed: 1982-07-20
Abstract: A circuit arrangement for electrically separately driving at least one power transistor by means of a transformer having a primary and at least one secondary winding, the primary winding of which is connected to control terminals, contains a storage device driven by the secondary windings, which is connected to the input of the power transistor and can be changed into a first switching state by means of a pulse of the first type fed into the control terminals and can be changed into a second switching state by means of a pulse of a second type, the power transistor being cut off in one switching state and conducting in the other switching state. To ensure rapid switch-over which, in turn, requires high control current, and to be able to manage without power output stage for the storage device, on the other hand, the secondary winding is connected to a pulse transfer device the output of which is connected to the input of the power transistor and which takes the electrical energy required for switching the power transistor from the pulses fed into the control terminals.

Title: Insert for a cable duct tube
IPC: H02G9/06
Filed: 1983-03-24
Abstract: In order to be able to lay cable protection tubes in the field of telecommunications in great lengths of, for example, more than 1000 m with a low time and labour cost, an insert for a cable duct tube is created in which a plurality of plastic protection tubes for holding individual cables are connected by means of flexible intermediate webs, which are integrally formed on their outer envelope surface, to form a protection tube flat web which can be deformed for laying inside a cable duct tube into a bundle of mutually adjacent, cohesive protection tubes whose circumferential contour approximates to a circle. The combining of the protection tubes to form a flat web as the basic material simplifies handling during laying and, furthermore, allows the protection tube unit to be worked directly into the ground. Pressure-sealing strips secure the shape of the tube bundle in the cable duct tube.

Patent DE-3322326-A1 (DE)
Title: Rotary closure for containers
Inventor: LECINSKI FRANK H JUN
IPC: B65D51/14
Filed: 1983-06-21
Abstract: A screw closure is provided which is composed of an annular part and a closure part. The closure part has the sealing compound which interacts with the container neck and is received in a snap-on manner in the annular part so as to be captive, but axially movable within limits and rotatable relative to said annular part so that, when the annular part is screwed onto the container neck, the closure part is pressed into a sealing position and, when it is released from the container neck by the screwing movement, is pushed off evenly over its circumference. In this case, the friction of the contact surface between the annular part and the closure part is considerably lower than the friction between the sealing compound and the sealing surface of the container neck interacting therewith, such that, in significant phases of the screwing-on and unscrewing movements of the annular part, the latter is relatively rotatable both in respect of the container neck and in respect of the closure part.

Title: Mixture-compressing internal combustion engine functioning with charge stratifying
Inventor: SCHAEPERTOENS HERBERT DIPL ING
IPC: F02D41/34
Filed: 1983-09-16
Abstract: A mixture-compressing internal combustion engine for vehicles, especially passenger motor vehicles, functioning at least at low and medium partial load with charge stratifying in an undivided combustion chamber, has a fuel injection device (8, 10), which during the inlet strokes injects the fuel by way of injection valves (8) into the respective intake lines (6) assigned to the individual combustion chambers (5) immediately upstream of or on the inlet valves (7). In order to obtain optimum operation for a low consumption, good running behaviour and in particular low pollutant emissions, especially in the NOx range, it is proposed that the injection device (8, 10) be designed in such a way that the injection ends on the admission stroke at a point lying at a fixed crank angular distance from the bottom dead centre and that its start be controllable as a function of the variables characterising the operating state of the internal combustion engine. <IMAGE>
Patent DE-3403910-A1 (DE)
Inventor: PIEPENBREIER ERNST
IPC: F16D3/68
Filed: 1984-02-04
Abstract: A double coupling comprising two flexible couplings are connected to each other through an intermediate hollow shaft and have outer parts on each and each with a hub and radially extending arms between which rubber blocks shaped as ring segments are inserted in a prestressed state. The rubber blocks each comprise a central, radially inwardly narrowing wedge to which two rubber members carrying plates on their free surfaces are symmetrically vulcanized on either side. The wedges are connected to corresponding claws of the intermediate shaft. The wedge and claws, along with the intermediate shaft serves as a common hub portion and form an inner part of the flexible coupling. One hub is secured to a solid shaft and the other hub is secured to a hollow shaft. The solid shaft extends through the hollow shaft and they move relative to each other, even in misaligned positions. As compared to similar prior art couplings for transmitting comparable power, the weight of such a doubling coupling is reduced.

Title: Method for controlling the print hammers of line printers and a circuit arrangement for carrying out the method
Inventor: ECSEDI ISTVAN DIPL ING
IPC: B41J9/14
Filed: 1984-04-16
Abstract: The invention relates to a method for controlling the print hammers of line printers and a circuit arrangement for carrying out the method. In accordance with the method, the control of the print hammers is ensured with consideration of the requirements regarding flight time for a duration longer than the adjustment of the character carrier in two successive character layers, two comparison subcycles being triggered in each character layer; during the first subcycle, in addition to the result of the comparison the hammer register has also input into it its own, preceding state by means of a logic OR connection and the control of the hammer takes place at the end of the first subcycle in accordance with the instantaneous state of the hammer register. In the second comparison subcycles, the cells of the hammer register are cleared, in which subcycles the control of the hammer must be switched off. The circuit arrangement suitable for carrying out the method contains, in addition to the hammer register (1), a memory register (2) with the same number of cells as that of the hammer register (1), and this memory register (2) is connected to the hammer register (1). The latter is realised with a shift register between whose series output and series input a feedback loop is formed via a logic circuit. <IMAGE>

Title: Fuel injection pump for self-ignition internal combustion engines
Inventor: VOGTMANN HANS-JOERG DIPL ING
IPC: F02M59/08
Filed: 1984-10-05
Abstract: A fuel injection pump is proposed, which has a stepped piston (9) working in a stepped bore (2, 3) which piston in the stepped bore includes a first pump chamber (14) and a second pump chamber (15), the second pump chamber (15) being connected by way of a non-return valve (16), opening in the delivery direction, together with a first feed line (17) of the first pump chamber to a distributing groove (21) on the pump piston, by way of which fuel is delivered into separate fuel injection lines (23) on the delivery stroke of the stepped piston. In idling operation and at low load a portion of the fuel fed from the second pump chamber (15) can be fed by way of a non-return valve (48) to an extraction chamber (40), the extraction volume of which determines the deflection travel of a deflection piston (41). The deflection travel is thereby determined by the duration of the relieving of the extraction chamber between the individual delivery strokes by way of a throttle (39).
