Title: Circuit arrangement for an asynchronous motor drive with variable speed.
Inventor: GYORGYI VIKTOR
IPC: H02P/
Filed: 1981-04-21
Abstract: A circuit arrangement for an asynchronous motor drive of controlled stepping, i.e. for control of the number of revolutions of asynchronous squirrel-cage motors, in which the output of the supply unit is connected to a potentiometer, the other terminal of which is connected to the common terminal of the abjusting resistors. The non-common terminal of one of the resistors is connected to one of the inputs of a switch-inductance, whereas the collector of a transistor is connected to the other input. The emitter of the transistor is connected to the negative pole of the supply unit, while one switching point of the switch-inductance is connected to one of the inputs of the NAND-gate having several inputs. There is a magnetic coupled control coil arranged in the system being common for the switch-inductance and the uncoupling coil, while there are as many circuits of identical layout consisting of the switch-inductances, the single abjusting resistors and the transistors, as the number of pulses required for the control. The NAND-gate is connected through a switch-amplifier to the control input of the inverter.

Abstract: A method and apparatus are provided for adsorbing water vapor from a mixture (6) thereof with a second gas to reduce the water vapor concentration in the mixture to below a permissible maximum concentration. The advance of the moisture front in a sorbent bed (10) during either adsorption or regeneration or both is detected by determining the change in the moisture content of the sorbent as a function of the capacitance of a capacitor (20, 21) in which the sorbent is the dielectric. During adsorption, capacitance must be observed by way of a capacitor at least at a point in the bed sufficiently far from the end of the bed to prevent effluent having a limiting maximum moisture content from leaving the bed. When the capacitance at that point has reached a predetermined value corresponding to selected moisture content on the sorbent, the ad- scrption or regeneration cycle is discontinued.

Abstract: In a process for the manufacture of sugar beet chips of a high dry-matter content, the wet sugar beet chips are mechanically pressed to give pressed chips, and the pressed chips are dried thermally. The resulting vapours are subjected to coarse dedusting. The vapours, which are still loaded with fine dust, are now passed into a heating chamber (3) of a prewarming device (1) or an evaporation device (12) and condensed therein. Most of the fine dust is now associated with the condensate, and only the remainder of the fine dust is removed together with the waste gas. The condensate loaded with fine dust can be prepared in a treatment plant (10). Before thermal drying, the pressed chips can be mixed with dehydrating organic substances, and the mixture can be pressed again mechanically. The water obtained in the pressing step is filtered and evaporated in the evaporation device (12). The resulting vapours are condensed, and the thickened organic substances are recycled to be again admixed to the pressed chips before they are pressed again mechanically. <IMAGE>

IPC: H04M11/06

Abstract: Digital data is inserted in quiet or "no speech" portions of the PCM encoded voice signal stream when such quiet periods are detected. The digital data is encoded in a two byte pattern in which the scaling bits (VUT) are set high and the sign bit (S) alternates in each eight bit byte. Four bits of each byte are thus reserved for scaling and sign purposes, but the remaining four bits (d7-d4 and d3-d0) are available for data transmission. Setting the three PCM scaling bits high and alternating the sign bit has the effect of indicating to the receiver that voice is not present. Recognition of such a signal by the receiver permits a detector to block the output at a speech terminal and to strip the scale bits from the input two byte patterns and pass the remaining bits as data to a data output.

Abstract: An apparatus to control the registration between a printed web (5) of material and a downstream web processing station (4) at which the printed web is, for example, cut, folded, cut and folded, or punched, at a particular location with respect to the printing on the web comprises a length registration station (2) in the web path between a printing station (1) and the web processing station (4), a print detector (3) along the web path between the length registration station (2) and the web processing station (4) to monitor the passage of printing on the web, an encoder (7) coupled to the web processing station (4) to provide an output signal indicative of the operation of the web processing station (4) and a control unit (6) which receives the output from the print detector (3) and the output signal of the encoder (7) and which provides an error output signal indicative of the difference in phase between the two. The error output signal from the control unit (6) causes the web path length through the length registration station (2) to vary to compensate for any error in the registration of the printing on the web (5) resulting from variations in the printed repeat length in the length of web extending between the printing station (1) and the print detector (3). The apparatus also includes further registration means (12,13 and 14, or 15) operated in dependence upon the output of the control unit (6) to compensate for any error in the registration of the printing on the web (5) resulting from variations in the printed repeat length in the length of web extending between the print detector (3) and the web processing station (4).

Abstract: Liquid is caused to circulate in a shallow tank which has an operational depth less than half the effective maximum distance across the tank. One wall 17 defines with another wall a corner 18 and a bubble curtain 19 is provided along the wall 17 adjacent the corner 18 which imparts to the liquid in the tank an upward vertical component of movement which is asymmetrical along the wall 17, causing greater vertical movement of liquid at said corner than at the other end of the wall. Liquid rising up the wall 17 moving away therefrom by reaction therewith will circulate with a horizontal component due to the asymmetrical arrangement of the bubble curtain. The invention can be applied to the separation of materials of different densities e.g. the separation of suspended solids or emulsified oils from waste water.

Abstract: A system for controlling the feedwater system in a nuclear power plant utilises a logic calculations subsystem (50) which selects an operational mode of the system to be monitored from a plurality of operational modes. A disturbance estimate calculations subsystem (52) contains a dynamic mathematic model of the feedwater system and compares measured system variables with corresponding dynamic model variables contained therein to produce signals representative of deviations therebetween. A modified feedforward calculations subsystem (54) utilises these signals and other system parameters as inputs to a steady-state mathematical model to produce control signals to determine valve positions and pump speeds so that the control valve flows, minimum control valve pressure drop, and feedwater pump flows are at their respective demanded values.
