Patent DE-3125508-A1 (DE)
Inventor: BANHIDY KALMAN DIPL ING
IPC: B22D11/04
Filed: 1981-06-29
Abstract: The multiple ingot mold is comprised on one hand of a box-shaped frame (1), laterally closed, which forms a hydraulic pressure chamber and is used to carry the individual ingot molds (5) and to supply them with water and, on the other hand, of several individual ingot molds (5) which contain each of them a water chamber (9) and are each provided either with an annular ejection slot or with a crown (12) of ejection holes. The upper face of the frame (1) comprises as many openings (7) as there are individual ingot molds (5); said openings (7) bring the cooling water of the frame (1) to the individual ingot molds (5). Each individual ingot mold (5) is provided at its lower face with water supply openings (13) which correspond to the openings (7) of the frame (1). The water supply openings of the frame (1) respectively of the individual ingot molds (5) are selected so that the frame (1) has crowns of holes (7) and the individual ingot molds (5) have annular slots (13) or vice versa, or so that both have crowns of holes. When the water supply openings (13) of the individual ingot molds (5) are facing the water supply openings (7) of the frame (1), the individual ingot molds (5) are set on the frame (1) and they are pressed against the upper face of the frame either by their own weight or by an additional force. There is thus established a connection between the inside of the frame (1) and the water chambers (9) of the individual ingot molds (5) so that the frame (1) and the individual ingot molds (5) form a complex multiple ingot mold.

Patent DE-3141890-A1 (DE)
Title: Steam power plant with superheater and recirculation of the exhaust steam, including the heat of compression, to the steam cycle
IPC: F01K21/00
Filed: 1981-10-22
Abstract: Steam power plant with superheater and recirculation of the exhaust steam, including the heat of compression, to the steam cycle. The steam cycle proposed is operated between the unsaturated, superheated state and the saturated to dry saturated state of a superheated or cold steam and thus avoids continuous heating and vaporisation of the feed liquid via the boiler or vaporiser. It is thus possible to carry out compression and hence recirculation of the working medium by means of turbocompressors, spiral compressors or piston compressors virtually without problems. 100% utilisation of the primary heat transferred to the cycle into mechanical work is thus possible in theory, without contradicting the laws of entropy. If cold steams (Freons) are used as working media, it is also possible to use low-level heat sources (e.g. water, air or soil heat, with or without temperature differences relative to the surroundings) and hence to open up a new regenerative energy source with a relatively high energy density (about 20 ... 40% of present-day thermal power plants). In the case of multiple reheating, a high useful work ratio (expansion work/compression work) can be achieved both with high- and low-level heat sources.

Patent DE-3151242-A1 (DE)
Inventor: GRUENER MANFRED ING GRAD
IPC: H01F7/18
Filed: 1981-12-21
Abstract: The drive circuit for an electromagnetic actuator for the impact element in a printer includes a series circuit of a drive transistor and of a switching transistor there being a reference resistor interposed which together with a Zener diode serves as a current limiter for the current through the drive transistor and the electromagnetic element. The two transistors are controlled in that each of the base electrodes is serially connected to the emitter collector path of a control transistor and the two control transistors in turn are connected to monostable multivibrators which are triggered concurrently but furnish pulses of different duration such that the switching transistor is turned off before the drive transistor. The current limiting permits utilization of residual electromagnetic energy from the preceding actuation pulse without incurring undue losses.
Patent DE-3151268-A1 (DE)
Title: Cutlery, in particular disposable plastic cutlery
Inventor: BANNERT PETER
IPC: A47G21/02
Filed: 1981-12-24
Abstract: In the case of cutlery, in particular disposable plastic cutlery, the items of which are moulded, preferably injection-moulded, from plastic with the handle and tool part integrally in each case and have a reinforcing profile over the length of the handle, a considerable improvement in the stability of the handle is to be achieved both in the principle direction of bending stress and transversely to the principal direction of bending stress. At the same time, secure gripping and holding as well as a comfortable position of the handle in the hand are to be improved. For this purpose, the cutlery items are to be constructed over the length of their handle with formation of an essentially S-shaped profile with a central wall strip and two outer wall strips. In this case, at least one of these wall strips is arranged essentially in a plane parallel to the principal direction of bending stress of the handle. In the case of the spoon and fork, the central wall strip is preferably arranged in a plane parallel to the principal direction of bending stress of the handle and, in the case of the knife, the central wall strip is preferably arranged in a plane perpendicular to the principal direction of bending stress of the handle while the outer wall strips then lie in the plane parallel to the principal direction of bending stress. However, a different selection of the wall strips lying in a plane parallel to the principle direction of bending stress of the handle is also conceivable and may be preferable in specific applications.

Title: Device for measured-value pickup on sheet and web working and processing machines
Inventor: MORGENSTERN BERND
IPC: B65H7/14
Filed: 1983-03-09
Abstract: The invention relates to a device for measured-value pickup on sheet and web working and processing machines, in particular for the purpose of determining the position of sheets and/or webs. The aim of the invention is to produce a device for measured-value pickup for determining the position of moving objects, which with low outlay on circuitry prevents the occurrence of discards. The object is to design the device for measured-value pickup in such a manner that measurement is possible without additionally applied non-reflecting layers, and that a smaller measured-value pickup made of simpler technical means is required. The object is achieved in that, in the device, the measured-value pickup is arranged on a guide element outside the plane of movement of the object to be measured and this element is fastened to a drive element serving for movement on a curved path, that an energy source serving for scanning the edges to be detected is arranged outside the plane of movement, and also that the measured-value pickup is arranged upstream of an evaluating device. Speed measurements are also possible with this device. <IMAGE>
Patent DE-3309885-A1 (DE)
Inventor: CHRISTMANN BURKHARD DR
IPC: B22D11/16
Filed: 1983-03-16
Abstract: An apparatus for determining the wear of a mold wall during continuous casting of metal by using at least one distance measuring sensor disposed in the mold wall to measure the instantaneous distance from the sensor to the casting. The surface of the casting adjacent the mold wall may be irregular, so the minimum value of the distance between the sensor and casting is stored and used as the current distance between the sensor and the inner mold wall. Mold wear is determined by subtracting the current distance between the sensor and the inner mold wall from the original distance, before the abrasive casting process began. The sensor signals are also used to determine when the mold geometry should be adjusted to compensate for the wear. This is accomplished by storing the maximum distance between the sensor and casting and subtracting the current distance from this maximum, since the maximum distance increases as the casting shrinks away from the mold wall.
