Patent EP-0019138-B1 (EP)
IPC: H02P21/10
Filed: 1980-04-28
Granted: 1988-11-09
Abstract: A control unit for regulating an asynchronous motor supplied with power from a three phase network by a line-controlled power converter which is DC coupled to a self-commutated inverter has a function generator and a current regulator which controls the stator current of the motor by the controlling rectifier valves in the inverter. Control of the stator current is a function of a predeterminable value of flux fed into the function generator. In a parallel control system, an actual-value computer and a load state control regulate the stator frequency by generating a signal for controlling the self-commutating converter as a function of the actual values of the stator current, the stator voltage, and a value calculated from the function generator input variable. The computer forms signals corresponding to the amplitude of the flux vector, and to a stator current component perpendicular to the flux vector. A variable derived from the predeterminable variable is applied to the load state control as a reference value. Fall-out-proof, low oscillation, speed control is effected from low angles to nearly 90 DEG .

Abstract: An industrial wastewater treatment method is described whereby heavy metals dissolved in the waste. water are precipitated as a siurry which, when allowed to settle, will form a sludge containing at least 10 weight percent solids. In the method, an aqueous suspension or solution of a neutralizing agent is introduced into a first reactor. A suspension containing particles of carrier agent is also introduced into the first reactor. A portion, if not all, of the neutralizing agent is adsorbed on the surface of the particles of the carrier, which are maintained in suspension in the first reactor. The carrier, with its adsorbed neutralizing agent, is passed to a second reactor and simultaneously the contaminated industrial wastewater is added to the second reactor. The pH of the wasterwater is adjusted to a range between 8.4 and 10.6 by the neutralizing agent. Within such pH range, a substantial portion, if not all, of the heavy metals are precipitated in the form of a slurry. The mixture in the second reactor is passed to a solids separation device. The solids in the slurry settle to the bottom of the device to form a sludge which is removed therefrom. Purified water is removed as an overflow from the separation device. Optionally. a flocculant may be added to aid in settling the solids.insoluble calcium salts may also be precipitated in the second reactor. Such insoluble salts are adsorbed on the surface of the carrier and/or the heavy metal slurry particles and become part of the sludge formed in the seperation device.

Abstract: The present invention relates to the cleavage of organosiloxanes with hydrogen chloride with the formation of organochlorosilanes. In accordance with the invention, this cleavage is performed at temperatures below 20 DEG  C., and the dihydrates and trihydrates of the hydrogen chloride are formed. These settle as the specifically heavier, liquid phase and thus can easily be separated from the organochlorosilanes. The preferred temperature range in which the procedure of the invention is performed is between +10 DEG  C. and -10 DEG  C., while yields of as much as 99% of the desired organochlorosilane are obtained. The process can also be performed continuously. The inventive process is particularly useful because it can be used to convert contaminated organosiloxanes, such as used heat exchange or hydraulic oil materials, into useful products.

Abstract: A tracking control device for a video tape recorder comprises a bimorph leaf on which a rotary playback head is mounted so as to be deflectable in a direction perpendicular to tracks to be scanned. A triangular wave signal generating circuit comprising cascaded flip-flops generates a substantially triangular wave signal which is supplied to the bimorph leaf to cause the playback head to wobble relative to the tracks. A detecting circuit detects an envelope signal in the signal reproduced by the playback head, and a phase comparing circuit which includes an exclusive-OR circuit compares the phase of this envelope signal with the phase of the triangular wave signal. The output of the phase comparing circuit is fed back to the bimorph leaf to effect tracking correction.
