Title: Method for determining the non-reversed bearing angle
Inventor: BUESS RALF
IPC: G01S3/24
Filed: 1985-05-15
Abstract: In direction-finding methods with sequential analysis of the phase angles between the signals of two crossed directional antennas and an omnidirectional receiving antenna by means of integrating phase-measuring devices, the determination of the bearing azimuth and the associated quadrant presents considerable problems when the received signals are keyed or have very small and in many cases also fluctuating amplitudes. According to the invention, the time intervals provided for analyzing the phase angles are automatically extended by the duration of keying intervals or amplitude dips which begin within these periods so that the shortening of the analysis periods otherwise occurring is compensated for. <IMAGE>

Title: Scrubbing water treatment for simultaneous SO2 and NOx gas purification
IPC: B01D53/68
Filed: 1985-06-01
Abstract: The main application P 3518358.6 relates to scrubbing water treatment in the simultaneous SO2 and NOx gas purification. A characteristic of this process is returning the iron-sulphate-containing filtrate of the oxidation stage for calcium sulphite to the absorption process of the SO2/NOx removal. This filtrate, in addition to Fe(II) sulphate also contains Fe(III) sulphate and forms Fe chelate solution again with EDTA. In order to further improve the simultaneous SO2/NOx removal technically and economically and, in particular, also to reduce the use of sodium dithionite, according to the invention, it is proposed that a part-stream of the scrubbing water circulation (1) reacts with Ca(OH)2 (2) in a vessel (3) and the suspension is prethickened in a thickener (4) and, using a belt filter (5) a solid product (6) of CaSO3, CaSO4 and Fe(II/III) hydroxide is produced, which is oxidized in the oxidizer by fresh water (7), sulphuric acid (8) and air (9), so that after filtration (12) a commercial end product CaSO4 . 2H2O is present and the filtrate (14) containing the FeII/III sulphate is fed to separate use. The basic filtrate (15) from the belt filter or centrifuge (5) is combined with iron(II) sulphate (17) and recovered EDTA (23) from the EDTA precipitation stage (20) using sulphuric acid (21) forming Fe(II)-EDTA complex solution and is returned via line (18) to the absorption circulation, where the mixture of the components ...

Title: Process and installation for regenerating activated coke and for the production of sulphur
Inventor: SCHLIPPER PETER DIPL ING
IPC: C01B17/04
Filed: 1985-06-05
Abstract: Activated coke which is to be regenerated, being loaded, for example, with sulphur compounds, is preheated in a heat exchange together with previously regenerated activated coke and is then fed to a regenerator designed as a filter bed. Therein the activated coke is thermally regenerated via a desorption circulation at approximately 500 DEG C. An amount corresponding to the desorbed SO2 is shunted off from the circulating gas and fed to an SO2 rich-gas processing stage. As a result of having a residual-SO2 removal stage connected downstream, in which the filter principle using a filter bed supplied by a small activated-coke part stream is again employed, the SO2 rich-gas processing stage does not have to be designed for very high efficiencies, which also results in a simple and thus operationally reliable and cost-effective installation for carrying out the process. <IMAGE>

Title: Control device for a regulated, unbalanced switching voltage source
Inventor: GAUTHERIN GEORGE A
IPC: H02M3/335
Filed: 1985-09-20
Abstract: The invention relates to a regulating control circuit for an unbalanced switching voltage source, having a device for controlling the switch operating cycle during the starting phase, furthermore for the normal mode and for the current limiting mode. In the normal mode, an operating cycle of less than approximately 50% is provided, but a low input voltage mode can be used for limited times, at operating cycles of 70 to 80%. A time base generator defines the maximum permissible switch conducting time and the switching speed. The input current is limited during starting in order to reduce the energy loss in the control circuit. The starting operating cycle is likewise kept to a low value in that the switch non-conducting time is extended. In the current limiting mode, the operating cycle is reduced as a function of the current requirement in order to maintain constant current operation over a given range of output voltages and to obtain a current reduction below this range. During the current reduction, the switch non-conducting period is extended in order to obtain unusually low operating cycles in the vicinity of short-circuit states.

Title: Device for feeding wire-shaped filler metal to a welding point
Inventor: DEIMANN ROLF DIPL ING
IPC: B23K9/12
Filed: 1985-10-02
Abstract: During welding with filler of the same type of material, in particular during TIG and plasma welding, a filler metal (Z) is fed laterally in wire form to the welding point. For a uniform welding quality, exact bearing of the wire-shaped filler metal (Z) against the workpiece surface (WO) is necessary here. This is achieved by a movable wire feed (DZ) with two tubes (R1, R2) which are arranged one after the other and through which the wire-shaped filler metal (Z) is passed to the welding point, in which arrangement the filler metal (Z) coming out of the front tube (R2) can be pressed against the workpiece surface (WO) by a torque (D) which can be induced in the area of the flexible connecting point of both tubes (R1, R2). The torque (D) can be applied in an especially simple manner by the preloading of a helical spring (SF) pushed over both tubes (R1, R2) in the connecting area. <IMAGE>

Abstract: To allow a cable to be led from the interior of a mobile power consumer (for example boat or caravan) to a fixed power connection without misappropriating existing openings, such as doors or windows, and to have the plug connected to it always ready for operation, a specially designed cable lead-through box 15 is fitted into an opening 19, especially made for this purpose, of the outer wall 18 in a watertight manner, for example by means of seals 20, and allows the cable 12 to be led through. When not in use, the plug 10 with the cable end attached thereto is enclosed in this lead-through box, which has a cable lead-through opening 7 which, in this operating state, is sealed in a watertight manner by an automatic closure device 8. When put into use, the closure cover 1 of the box 15 is opened, the plug 10 is brought out and pulled through the box with as much cable as is necessary to connect the plug to the power source. Then, the cable is placed into the cable lead-through opening 7, likewise opened when the cover 1 is opened, whereby its closure device 8 is automatically opened to the extent necessary for receiving the cable and then the box cover 1 is closed again. This seals it, and with it the part of the cable on the user side, in a watertight manner. <IMAGE>

Title: Method for controlling and regulating a synchronous machine
Inventor: HUSSELS PETER DR ING
IPC: H02P21/10
Filed: 1986-01-30
Abstract: For a method for controlling and regulating a synchronous machine which is operated from a converter and has indirect flux orientation, that is to say the flux position which is required for control is calculated from the rotor position and the reference variables for the currents and an additional determination of the components of the actual voltage value with respect to the precalculated position of the flux, it is intended that no rotor position transmitter be required and no integrators be provided, which drift and tend to damp oscillations when this drift is compensated for. This is achieved in that the deviation of the I component of the voltage vector is supplied from the reference value, which is precalculated in the machine model, to a first flux regulator (11a) whose output signal is added to the reference value for the excitation current, in that either a tachogenerator (4) with a downstream-connected sine/cosine generator (12) or only one of the latter is used to determine the rotor position (cos lambda , sin lambda ), a suitable, controlled preset for the angular velocity ( omega 0) being made for said generator during starting from the rotation speed of zero, in that the deviation of the m component of the voltage is supplied to a second flux regulator (orientation regulator) (11b) whose output signal is likewise supplied to the sine/cosine generator (12), additively to the tachogenerator and/or the angular velocity preset value. <IMAGE>
