Patent DE-3109715-A1 (DE)
Title: Mould inlet for the horizontal continuous casting of steel
Inventor: TROEMEL KRISTOF W DR ING
IPC: B22D11/047
Filed: 1981-03-13
Abstract: The invention relates to a mould inlet for the horizontal continuous casting of steel, the said inlet having a section which widens towards the mould between the outlet opening of the vessel containing the molten steel and the said mould. This leads in the prior art to a sudden increase in cross-section and, as a result, to disturbances in the flow which disturb the uniform entry of the molten steel into the mould and cause severe damage to the surrounding refractory material by erosion. The invention avoids these disadvantages by continuous widening in the direction of flow to virtually the full size of the mould. The continuous widening of the cross-section both eliminates the disturbances in the flow of the molten steel, which can come into immediate contact at the inlet with the mould walls and solidify to form the strand shell, and simultaneously ensures that the conditions for the refractory material are much less severe.
Patent DE-3111342-A1 (DE)
Title: Electrical current generating element
Inventor: PIAZOLO PIUS DIPL ING
IPC: H02N11/00
Filed: 1981-03-23
Abstract: The basis is an effective unit consisting of the interacting properties of magnetic-electrical induction and of thermodynamics, and the associated wire loops. The Möbius strip is used as a matrix for the method of operation. In this case, the wire loops run like a mesh in the same way as the transverse thread and the magnetic field migrations - the switched rotator mechanism in a ring-like track - in the same way as a longitudinal thread. In the thermodynamics method of operation, in contrast, the magnetic field migration and the wire loop have the same axis direction, in order to convert electrical energy into heat. In this case, it is not only the case of storing the extracted electrical energy, but of simultaneously also dissipating the same heat for thermodynamic interaction in the system of magnetic-electrical induction. The structure of the Möbius strip actually facilitates this interaction. The circumferential tracks of the lines of the bisections and trisections allow temporarily rising interactions to come into play. The economy is achieved because suitably reconfigured superconducting switches are used for the switching and magnetic elements. Families of magnetic field migrations can then be assembled by means of integrated circuits to achieve a programmed efficiency. <IMAGE>

Title: Digital cosine generator
Inventor: KOFFLER HANS DR ING
IPC: H03H17/00
Filed: 1981-03-30
Abstract: The invention relates to a digital cosine generator based on the wave digital filter principle. The generator requires only two memories, a multiplier and five adders. Its circuit arrangement represents a parallel resonant circuit with infinite quality. An amplitude, once entered, is therefore retained. The frequency is defined via a modification of the gain factor. This cosine generator has a circuit arrangement in which two adders (1, 2) are connected in series. The output of the second adder (2) is fed to the output (0) and simultaneously connected to the first input (31) of a third adder (3). The inputs of all adders are designated with the indices (1 and 2), and their outputs with the index (3). The output (33) of the third adder is connected to the first input (41) of a fourth adder (4) whose output is connected via a delay component, a memory (6) to the input (51) of a fifth adder (5). A second memory (7) is connected to the output (33) of the third adder (3). Its output is connected to the inputs (11) and (52) of the first and fifth adders. The output (53) of the fifth adder is connected to the second input (42) of the fourth adder and to the input of a multiplier (8). The output of this multiplier is connected to the second inputs (12) and (32) of the first and third adders. A start-up device (9) is connected to the second input (22) of the second adder, via which the maximum amplitude value is entered. <IMAGE>

Title: Method of recovering environmental heat for heating purposes or the like by means of a refrigerant circuit, evaporating a refrigerant, and refrigerant circuit
Inventor: MARTENS JUERGEN
IPC: F25B49/02
Filed: 1981-05-14
Abstract: In a method of recovering environmental heat for heating purposes, a refrigerant circuit is used, in which a refrigerant is evaporated, compressed in a compressor, liquefied giving off heat and subsequently evaporated again, being relieved, the sensible heat of the compressor being carried off by means of cooling by the refrigerant to the medium to be heated. In order, using the sensible heat of the compressor, to increase the thermodynamic efficiency of the method or circuit and to utilise more fully the evaporator surfaces, refrigerant vapour with liquid phase is generated in the evaporator, which uses unevaporated refrigerant for cooling the compressor, and the refrigerant vapour is superheated by the heat absorption from the compressor. In this case, the suction nozzle of the evaporator is connected to the compressor cooler and the cooler outlet to the suction nozzle of the compressor, while the sensor of the expansion valve provided for the thermostatic evaporator superheating control is situated between cooler outlet and compressor suction nozzle. The advantages consist in particular in a simplified structure and a considerably improved utilisation of the energy which is released in the circuit.

Patent DE-3148271-A1 (DE)
Title: Device for controlling and non-volatile storing of the rotation direction of a motor
Inventor: STEIN MANFRED
IPC: H02P7/03
Filed: 1981-12-05
Abstract: In a device for controlling and non-volatile storing of the rotation direction of a motor, at least one switch which is arranged in a motor circuit can be reversed into in each case a bistable position by an electrical reversing pulse. The operating reliability of such a device is improved in that the switch can be reversed by an electronic bistable multivibrator whose one control input has the reversing pulse applied to it and is subjected to only small tolerances of the switching threshold. For rapid and reliable reversal, a ferromagnetic element is furthermore provided which has high remanence and stores the rotation direction of the motor. This ferromagnetic element is magnetically coupled by the multivibrator to a reversible circuit, preferably to the motor circuit, and is fed back via a read line to a control input of the multivibrator. Thus no additional switches and no auxiliary energy is required for reversing the ferromagnetic element in the arrangement of the ferromagnetic element in the motor circuit. <IMAGE>

Title: Process for the continuous production of pressure-moulded coal
Inventor: YOSHIDA HIROSHI
IPC: C10B45/02
Filed: 1982-10-06
Abstract: The invention relates to a process for producing pressure-moulded coal for use in block-charging of coke ovens, the coal raw material being first pressure-moulded, a part of the coal pressure-moulded in this way being caused to remain in the mould cavity, while the next coal raw material is charged for pressure-moulding and this pressure-moulded coal is combined with the original coal so that, in continuous production of pressure-moulded coal, the pressure force exerted on the coal being pressure-moulded afterwards can be absorbed as a result of the frictional force between the pressure-moulded coal and the wall of the mould cavity. After the pressure-moulding step, the pressure-moulded coal is ejected from the mould cavity by application of further pressure to the pressure plate. <IMAGE>

Title: Method for receiving-end recovery of the carrier and clock in digital quadrature amplitude modulation (QAM)
Inventor: BESSAI HORST DIPL ING
IPC: H04L27/38
Filed: 1982-12-11
Abstract: The invention provides a method for receiving-end recovery of the carrier and clock in digital quadrature amplitude modulation (QAM). It is based on the assumption that the carrier frequency selected at the transmitting end is identical to the data bit rate. According to the invention, one of the system-enabled signal states serves as a reference phase angle which is identified at the receiving end through evaluation of the normal and quadrature components by means of a logic 7. This logic generates identification pulses only when the selected reference phase angle occurs, from which pulses a control voltage for a voltage-controlled oscillator 9, which generates the carrier and clock frequency, is obtained via a loop filter 8. The signal state with the highest amplitude and a 45 DEG phase angle is selected as the reference phase angle. The logic 7 comprises an AND element to which the output of the two threshold value discriminators 6, allocated in each case to the highest amplitude stage, is connected, which discriminators are provided in each case in the regenerator for the normal or quadrature component (Fig. 1). <IMAGE>
