Patent DE-3329437-A1 (DE)
Title: Circuit for controlling power switching transistors with galvanic separation
Inventor: KOSMAC MIRAN
IPC: H03K17/60
Filed: 1983-08-16
Abstract: For controlling a power switching transistor (MST), two non-ideal electric generators (Ig1, Ig2), three transformers (TR1, TR2, TR3), diodes and other necessary passive elements are used. The turning on or off of the power switching transistor depends on the signals (VH1, VH2, VH3) at the input of bipolar transistors (T1, T2, T3). If the bipolar transistors conduct alternately, electric generators (Ig1, Ig2) feed the transformers, which supply the current via galvanically separated windings for turning on the power switching transistor. For turning off the power switching transistor (MST), the third transistor (TR3) activates the third transformer, which forms a voltage with directly opposite polarity at the base of the power switching transistor and thereby turns it off. Diodes in the circuit of the third transformer prevent leaking away of the base current when the power switching transistor is turned on. <IMAGE>

Title: Coal liquefaction process using an extraction of the liquid fractions by means of supercritical vapour to remove particulate solids
Inventor: GANGULI PARTHA S
IPC: B01D11/02
Filed: 1984-02-15
Abstract: A coal liquefaction process for producing liquid and gaseous hydrocarbon products, wherein fine particulate solids are removed in situ from the suspension liquid leaving the reactor using solvent vapour originating from the process under supercritical conditions. In this process, a coal/oil charge is liquefied and hydrogenated at a temperature of 340 to 480 DEG C (650 to 900 DEG F), and the resulting liquid suspension fraction, which contains fine particulate solids, is contacted with a solvent vapour fraction originating from the process and having a normal boiling range from 120 to 200 DEG C (250 to 400 DEG F) under supercritical conditions, in order to dissolve and to extract essentially the whole hydrocarbon liquid fraction and to separate off the particulate solids contained therein. The resulting solvent vapour with the dissolved coal liquid fraction is reduced in pressure and distilled for recovery of the required solvent fraction and for obtaining a hydrocarbon liquid fraction product. The coal liquefaction stage is preferably catalytic. The supercritical solvent vapour extraction stage, if appropriate inserted between two series-connected coal liquefaction reaction zones, can also be used for producing solids-free, liquid and gaseous ...

Title: Process and apparatus for milling saw teeth with a positive angle of rake in a metal strip, in particular in a bimetallic strip
Inventor: KOTTMANN KARL HUGO
IPC: B23D65/04
Filed: 1984-09-07
Abstract: In order to mill positive angles of rake in metal-cutting band saws, a cylindrical plain milling cutter with suitable milling teeth, the milling axis of which is arranged in the centre plane of a pack of strips, is moved by the angle of rake obliquely with respect to its axis, that is with a radial and an axial feed component. During this movement, it mills teeth gaps step by step into a section of the strips. By means of different feed displacements when travelling forwards and backwards, saw teeth back and saw teeth front can be produced with a shape other than that of the milling teeth, as shown in the drawing. On a horizontal plane, the clamping carriage with the strips can be displaced axially and the milling housing with the milling tool can be displaced radially with respect to the milling axis on guides. The two setting devices are either connected by an adjusting gear mechanism or are provided with separate drives jointly controlled on an open-loop or closed-loop basis. Adjustment and open-loop or closed-loop control are performed by preselection, sensing of a cam disc or a computer program. <IMAGE>

Title: Combination of water-steam and gas turbine processes
Inventor: RETH ANNO VON DR
IPC: F01K23/06
Filed: 1984-10-02
Abstract: A combination of two or more pressurised water-steam and gas turbine processes is applied for, in which the gas turbine process is characterised by precooling and/or intermediate cooling of a special type: the cooling takes place at least partially only up to a temperature level significantly in excess of the ambient temperature. All the heat dissipated in the cooling can be transferred to the water-steam process. In this process heat is generally transferred to two or more waste heat boilers under different pressure. The gas turbine process may be designed as an open, semi-closed or closed process. An increase of the overall efficiency is achieved - especially in the case of smaller plants.
