Title: Means for adjusting the pressure of air-cooled condensing apparatus
IPC: F28B11/00
Filed: 1960-12-20
Abstract: 928,006. Automatic pressure-control systems. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Dec. 20, 1960 [Dec. 31, 1959], No. 43706/60. Class 38 (4). In a system for adjusting a water pressure prevailing at the highest point of an aircooled condensing system the pressure at the inlet of a pressure-reducing device and that at the delivery of a circulating pump are detected and signals from the detectors are weighted and integrated to derive control impulses for a control arrangement for the pressure reducing device. As shown, the cooling water for a mixing condenser 1, wherein exhaust steam from a turbine is cooled by a water-spray 11, is withdrawn through a pipe 2 by an insulating pump 3 delivering through a pipe 4 to an aircooled heat-exchanger 6. The return flow to the condenser 1 is through a water-turbine 9 having a shaft, not shown, coupled to the shaft of the circulating pump 3. It is shown in the Specification that the pressure at the highest point 12 of the heat-exchanger 6 can be maintained constant by maintaining the sum of the pressures at inlet 14 of the water-turbine and at the delivery 13 of the pump constant. When the loss of head between the delivery of the pump and point 12 does not equal the loss between point 12 and the inlet of the water-turbine, the pressure at the pump delivery is weighted in the ratio of the losses. The electrical resistances of pressure transducers 15, 16 responsive to pump delivery pressure and turbine inlet pressure respectively, are summated at the input to a device 17 and compared with a reference valve. The resultant error signal controls the operation of device 18 causing an adjustment of the inlet cross-sectional area of the water-turbine so as to maintain the sum of the pressures constant. In a modification, the waterturbine is replaced by a pressure-reducing valve, the cross-sectional area of which is controlled by the device 18.

Title: Electric closed-loop regulating means
Inventor: SEYDEL GABRIEL MARIE HERMAN
IPC: H02P9/00
Filed: 1962-11-23
Abstract: 1,071,654. Automatic voltage control. ENGLISH ELECTRIC CO. Ltd. Nov. 22, 1963 [Nov. 23, 1962], No. 44381/62. Heading G3R. A closed-loop regulating system for varying the excitation of a generator so as to regulate the generator output voltage is provided with a reference source which provides a modified reference signal when the generator is accelerating from stand-still so as to prevent excessive excitation during this period. As shown, an alternator 10 has a field winding 12 energized from a D.C. supply source 13 under the control of a closed-loop voltage regulator 14. The reference voltage for the regulator 14 is derived from a source 16 which comprises a tacho alternator 17 coupled to the alternator 10, a network 19 for rectifying the speed-responsive output voltage of the tacho alternator, a smoothing circuit 20, and a load circuit 23 which has a relatively high impedance and is constituted by resistors 24, 25, and a Zener diode 26. The arrangement is such that the reference voltage across terminals 15 rises in proportion to the current flowing in the resistors 24, 25, and hence in proportion to the speed of alternator 10, until the Zener voltage of diode 26 is reached at a certain speed, e. g. 90% of the normal speed; the reference voltage then remains constant at the Zener voltage for further increases in speed. The reference voltage thus rises linearly to a constant value as the alternator accelerates from rest to normal operating speed, and the regulator maintains the energization of the field winding in accordance with the changing reference voltage so that excessive excitation does not occur.
