Patent DE-3101336-A1 (DE)
Title: Process and device for producing dry plasterboards and mouldings
Inventor: QUANTE HEINRICH
IPC: C04B40/00
Filed: 1981-01-17
Abstract: In the production of dry plasterboards and mouldings from binders and, if appropriate, aggregates, the binders are mixed with water, pressed and then subsequently dried, for example between two cardboard sheets. During this the addition of excess water is reduced or dispensed with entirely by mixing the binders or binder mixtures with water at high temperatures, in particular close to the dehydration temperature, and then pressing, with or without cardboard sheets, without prior cooling, to form mouldings. The binders are preferably mixed at 85-95 DEG C and subsequently pressed in stages initially at 3 and then at 6 N/mm<2> and subsequently dried. By the addition of selected aggregate materials, lightweight components, incombustible moulded parts or weather-resistant mouldings and boards having very good mechanical properties can be produced, for example from alpha-hemihydrate and Portland cement. The process can be expediently implemented with the aid of an intensive mixer having thermal insulation and a heat-pressing device. <IMAGE>

Title: Locking device for a lock, especially a vehicle-door lock having two different keys
Inventor: KOPPERSCHLAEGER DIETER DR
IPC: E05B49/00
Filed: 1981-01-30
Abstract: The invention relates to a locking device for a lock, especially a vehicle lock having two different keys, namely a normal key (N-key) and a special key (S-key) which, in addition to normal securing, also brings about a special securing of the lock. So that a space-saving construction is achieved and there is nevertheless a high degree of safety against probing in break-in attempts, the cylinder core of the lock is provided with perforations for electromagnetic radiation and the S-key is provided with potential conduction points for the electromagnetic radiation which, when the S-key is inserted, are aligned with the passages in the cylinder core. The cylinder guide surrounding the cylinder core is respectively provided, in the path of rotation of the cylinder-core passages, with mutually aligned transmitters and receivers for the electromagnetic radiation which define electromagnetic operating planes offset in terms of rotation relative to the zero position of the cylinder core which allows the N-key and S-key to be inserted and withdrawn. The receivers are each connected to an electronic evaluator which is programmed to the conduction-point code of the S-key and the output of which is connected to the lock members of the special securing device. <IMAGE>

Title: Device for preparation of liquid feed for animal feeding
Inventor: RIESSELMANN WERNER
IPC: G01G17/08
Filed: 1981-02-06
Abstract: A device for preparation of liquid feed for animal feeding has a silo or mixing container located on scales, into which the individual feed components are placed in dependence on the quantity indicated by the scales. Devices of this type are only operated at predetermined times, that is usually directly before feeding times. Uneconomic idle times thereby result. By disposing further platforms or the like, in addition to the containers, on the scales, the device can also be used for other purposes than solely for feed preparation or feeding, for example for weighing animals, harvested root crops, potatoes etc. This measure has the advantage that the actual time of operation of the device is extended and consequently its use in an agricultural enterprise is more economical.

Patent DE-3128713-A1 (DE)
Inventor: ARNOLD WINFRIED
IPC: A01B63/111
Filed: 1981-07-21
Abstract: To render the mixing relationship of mixed actual pulling force signals and actual positioning signals independent of the level of the respective individual signals, and thus avoid resetting of a manual positioning command element (7) upon change of respective relationships of pulling force and position, for example depth of furrow of a plough upon change of soil consistency, the force signal is normalized or rendered of equal value with respect to the position signal, preferably in accordance with predetermined events, such as change in the positioning command element, sensing of excessive pulling force, or the like, so that the normalized force signal and the actual position signal will be in balance, and relative change thereof in the mixer will not cause uncontrolled change in the position of the load, for example the plough, without resetting of the command element (or, conversely, require resetting of the command element upon change in relationship of the mixed signals).

Title: Method and device for cleaning and preparing the pressing faces of hydraulic presses
Inventor: BELSCHNER ERNST
IPC: B30B15/00
Filed: 1981-08-03
Abstract: Method and device for cleaning and preparing the pressing faces of hydraulic presses. To make it substantially easier to clean the pressing faces and to apply a release agent to said pressing faces, for example of a surface gluing machine for wood finishing, and to eliminate any danger to the operator, the invention proposes first of all applying, for example, a release paste to the two rough outer coverings of a cleaning device and then placing said device between the lower and upper pressing face of the hydraulic press and then raising and/or lowering the press to such an extent that the outer coverings of the cleaning device, which spread apart resiliently, exert sufficient pressure on the lower and upper pressing face of the press. By moving the cleaning device back and forth in a slowly progressing manner by means of a hand-held rod, the upper and lower pressing face of the press are cleaned and at the same time prepared in a simple and safe manner in a single operation. <IMAGE>

Title: Method of fabricating a semiconductor device
Inventor: CLAUSS HERMANN DR
IPC: H01L21/225
Filed: 1981-09-16
Abstract: In a method of fabricating a semiconductor device, one surface of a semiconductor body is coated with a first insulating layer in which a first opening is made for fabricating a first semiconductor zone and a second opening for fabricating a second semiconductor zone. A second insulating layer is deposited on the surface having the first insulating layer and the two openings and the material of the second insulating layer is removed from the second opening in the first insulating layer by means of the photoresist procedure. To produce the second semiconductor zone, impurities are introduced into the semiconductor body through the exposed opening in a preliminary process, the second semiconductor zone being driven more deeply into the semiconductor body in one or more postdiffusions. Then the material of the second insulating layer is also removed from the first opening in the first insulating layer and the first semiconductor zone is fabricated in the semiconductor body through the first opening.

Title: Circuit element of a fluid-circuit unit
Inventor: PHELPS ALEX
IPC: F15B13/08
Filed: 1981-10-22
Abstract: A circuit element of a fluid-circuit unit is arranged between plane surfaces of two components and has at least one slot (2, 3, 4) and/or at least one groove in which a fluid can flow parallel to the plane surfaces of the two components. A flexibly deformable sealing material (7) is attached to the boundary wall of the slot and/or the groove. This sealing material is held against moving outwards away from the boundary wall and has an axial extent which is smaller where the sealing material is attached to the boundary wall than at a point remote from the boundary wall. When the circuit element is clamped between the two components, the sealing material is pressed inwards into the slot and is deformed on each side to form a type of sealing lip which bears against the adjacent plane surface of the one or the other component. By the pressure of the fluid flowing through the slot or the groove, this sealing lip is pressed with increased force against the plane surface of the relevant component so that reliable sealing is ensured even at high pressures. <IMAGE>

Title: Branched length of pipe through which fluid flows
Inventor: GRASSHOFF ALBRECHT DR ING
IPC: F16L41/02
Filed: 1982-02-24
Abstract: A description is given of a length of pipe through which fluid flows, having a plurality of branches, of which at least one is not involved in the main flow. A guiding device in the interior of the length of pipe halves the fluid flow such that approximately half of the main flow flows essentially undisturbed through the length of pipe while the remaining part of the main flow is diverted via the branch not involved per se in the main flow. The formation of dead zones is thereby avoided and this is of considerable advantage particularly in the cleaning of such pipe systems by means of flushing fluid.

Title: Method and device for automatic control of a cutting machine
Inventor: EVANS DONALD J
IPC: B65H23/04
Filed: 1982-05-22
Abstract: A moving material web (10) can be subdivided into an leading section (62) having a first set of adjustment marks and a trailing section (64) having a second set of adjustment marks. A target mark (26) is provided on a transition section between the first and the second sets of adjustment marks adjoining the first mark of the second set. Said target mark is detected and electronically tracked to a rotary shear (16). During a change of job or a change of shear within a job, the material web (10) is automatically severed by the rotary shear (16) twice or more frequently in the transverse direction, so that a part of the leading section (62) and of the trailing section (64) including the transition between the sets of marks is cut out. The front edge of the trailing section (64) is tracked to a station between the rotary shear (16) and the cutting machine (20). The blades of the cutting machine shear or straighten the trailing section (64) at the first adjustment mark following the front edge thereof and subsequently automatically cut the trailing section synchronously with the second set of marks into blanks. The blades of the cutting machine are held in the mark cutting operating mode without loss of synchronisation at the part of the material web cut out by the rotary shear (16). There is no need for the user to intervene, and the amount of waste is minimised. <IMAGE>

Patent DE-3225990-A1 (DE)
Title: Thyristor having at least four zones of opposite conduction type
Inventor: SCHLANGENOTTO HEINRICH DR RER
IPC: H01L29/08
Filed: 1982-07-12
Abstract: Such semiconductor devices are provided on the cathode side or anode side with emitter short circuits which are able to increase, inter alia, the dv-dt load carrying capacity and reduce the critical hold-off interval. Among the disadvantages of emitter short circuits are a delaying and possible impedance of the propagation of triggering when the thyristor is turned on, an increase in the latch-up current and possibly an undesirably high holding current, and, in the case of GTO thyristors, only a low resistance to excessive currents. The invention provides an emitter-base structure in which the disadvantages of shorting are avoided or reduced and the dynamic properties are improved further. This is achieved if an emitter-base junction is so highly doped at a multiplicity of points on both sides distributed over the area and has such a high doping gradient at the junction that the characteristic of the p-n junction is determined at those points by the tunnel mechanism.
