Title: Method for controlling and regulating a synchronous machine
Inventor: HUSSELS PETER DR ING
IPC: H02P21/10
Filed: 1986-04-10
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 necessary for control is calculated from the rotor position and the reference variables for the currents, and the components of the actual value of the terminal voltage are additionally determined, the object exists of compensating for the errors in the rotor model during the calculation of the reference variables for the angle  delta  and during the calculation of the reference variable for the energy current iE, by means of a feedback. This is achieved in that the coordinates (um, ul) of an actual voltage value (u alpha , u.) with respect to the precalculated position of the flux are determined with the aid of a coordinate rotating element (3'), in that the error between the I component of the voltage vector and the reference value  psi  is supplied to a first flux regulator (11a) whose output signal corrects the parameter Lh in the rotor model, and in that the error between the m component of the voltage of the flux and the required value is supplied to a second flux regulator (11b) whose output signal is used for correction of the model parameter Lhq/Lhd. <IMAGE>

Title: Process for treating scrubbing liquid in the simultaneous SO2/NOx purification of flue gases
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-06-10
Abstract: In the main Application P 3611475.8, it is described that the reduction of the Fe(III)-EDTA complex to give the Fe(II)-EDTA complex active in NOx scrubbing is performed by dissolved sulphite in the scrubbing solution. It is established in this case that this reduction is, inter alia, time-dependent and the incorporation of a delay vessel for the scrubbing liquid is advantageous. It has now been found that the abovementioned reduction is also temperature-dependent, so that it is proposed that a delay reservoir is provided for the entire scrubbing solution of the process or a part-stream for the reduction of Fe(III)-EDTA complex with dissolved sulphite of the scrubbing solution and the residence time is set in the range from 20 min up to 3 h, preferably from 60 min to 120 min. The temperature of the scrubbing solution in the SO2/NOx purification system or in a special regeneration tank which is designed as a delay reservoir is 40 DEG C to 70 DEG C, preferably 45 DEG C to 65 DEG C.

Title: Circuit arrangement for regulated high-energy pulse generation for gas-discharge flash lamps
Inventor: STEINBACH GUENTER
IPC: H05B41/34
Filed: 1986-10-02
Abstract: A circuit arrangement for regulated high-energy pulse generation for gas-discharge flash lamps. A very bright and well reproducible light source is required for many technical applications. A large number of optoelectronic measurement methods can be implemented, using the single-beam method, with such a reference flash. Until now, it was necessary to work using the two-beam method in the case of such measurement methods, in the case of which two-beam method the instantaneous illumination intensity and spectral distribution of the light of the flash lamp must also be detected by metrology means. By operating the flash lamp using a constant high-current source with a current intensity of up to several hundred amperes, a constant illumination intensity, which can be reproduced well in terms of time, is produced, to a first approximation. Further improvements of the time constancy of the illumination intensity have been achieved by further variants of the circuit arrangement. Such well reproducible lighting devices are required for rapid colour measurement. Such reference flashes open up a wide range of applications in optoelectronic metrology and physical electronics. The large number of application possibilities include turbidity measurement in liquids, spectrometry and the optimisation of optoelectronic components (sensors, solar generators).

Patent DE-3640136-A1 (DE)
Title: Compression device
Inventor: JUENGLING HELMUT
IPC: F01B9/02
Filed: 1986-11-25
Abstract: The subject of the invention is a compression device which has the object of essentially augmenting the force applied in the final compression of air or gases in a cylinder. As a result, the effective power output of the product in question is increased due to less loss of power, for example in the operation of compressors, pumps and other applications, by means of eccentric designs of the end of the pushrod or connecting rod and appropriate arrangement with respect to the piston. This is achieved in that the pushrod or connecting rod is formed eccentrically on the piston in such a way that the eccentric presses against a roller, a ball or roller bearing, a pivot pin sliding in an elongated slot or other arrangement and by means of an unsupported length according to Fig. 1 (a) significantly augmenting the thrust force applied, for example by way of the lever (9). It is advisable, for a special application, to design the roller (4), and/or the rod end (7) as an eccentric. <IMAGE>

Filed: 1986-12-08
Abstract: The invention relates to a winding apparatus for threads, with a fixed driving roller and with a bobbin which is clamped in a U-shaped bobbin lever between coaxial clamping plates and which rests on the driving roller and is driven by the latter. According to the invention, the bearing of the bobbin on the driving roller as the bobbin diameter becomes larger is controlled in such a way that an optimum bobbin build-up is obtained. In order to control the drift of the generatrix by which the bobbin rests on the driving roller in conformity with an optimum bobbin build-up in the course of the winding run, according to the invention the bobbin lever in which the empty tube is clamped is pivotable about two parallel pivoting shafts. The pivoting shafts are guided on respective guide tracks. One guide track is mounted on the mutually confronting sides of the sideplates of the bobbin lever, and a sliding block fastened on one pivoting shaft of the bobbin lever is guided in the guide track. In addition, a one-sided pivoting lever is respectively mounted, on the mutually confronting sides of the sideplates of the bobbin lever, on a pivoting shaft, the free end of which is articulated on the bobbin lever on the second pivoting shaft. By means of a force transmitter acting on the pivoting lever, the force with which the bobbin rests on the driving roller can additionally be influenced in the course of the winding run.

Title: Cylinder head for an internal combustion engine
Inventor: HAAS ECKHARD
IPC: F02F1/24
Filed: 1987-08-27
Abstract: The invention describes a cylinder head (1) for an internal combustion engine with a slot (11) fitted in the web (2), which slot is filled with a web insert (12). The web insert has an expansion gap (14) in the middle, which is closed to the combustion chamber on the combustion chamber side and thereby durably protected from combustion residues. The expansion gap (14) ensures that, during warming up of the cylinder head, the hot web section can expand unimpeded. Due to the stress reduction, the temperature in the web area is reduced, and the material compressive yield point increased, so that the tensile stresses occurring as the cylinder head cools do not cause cracks in the web area or permanent deformations of the valve openings (Fig. 1). <IMAGE>
