Patent CA-1121452-A (CA)
Inventor: KONISHI HIROO
IPC: H02J1/00

Granted: 1982-04-06
Abstract: ABSTRACT OF THE DISCLOSURE         A pair of thyristor converters are connected by a DC power transmission line, and their AC terminals are connected through tapped transformers to AC systems respectively.  The output signal of a constant-current circuit in a converter control unit associated with the forward converter is selected to control the gate of the forward converter, while the output signal of a constant-voltage circuit in a converter control unit associated with the reverse converter is selected to control the gate of the reverse converter.  When the reactive power is to be controlled, a reactive power signal is applied for the gate control.  A voltage limit indication circuit in each control unit receives the AC terminal voltage e2 of the transformer and the DC current Id so as to increase the control angle limit with a decrease in the values of e2 and Id.  When the control advance angle or control delay angle determined by the output signals of the control circuits is larger than the control angle limit, this angle is limited to the control angle limit.  When the reactive power is to be controlled, the tap position of either transformer is lowered to decrease e2 and to increase the control angle limit thereby widening the controllable range of the reactive power.  During the start-stop stage or during the protective operation, the output of the voltage limit indication circuit in each control unit is inhibited to permit free variations of the control angle.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a new process for the simultaneous production of magnesium and cement from calcined dolomite or calcium and cement from calcined lime.          According to the invention calcined dolomite or calcined lime is reduced under a pressure lower than 10 torr and at a temperature of 1300 to 1600 °C with a reducing agent containing silicon and aluminium in a weight ratio of 4:1 to 1:1, wherein the total amount of silicon and aluminium comprises 50 to 100 % by weight. 100 to 200 parts by weight of the reducing agent are applied to convert 600 to 800 parts by weight of calcined dolomite or 700 to 1000 parts by weight of calcined lime.        In contrast to the known procedures, the new method according to the invention provides cement as by-product instead of a useless slag.

Abstract: ABSTRACT OF THE DISCLOSURE           A digital servo control system for controlling a drive motor accumulates speed and phase error numbers and produces a pulse width modulated signal in response thereto. Phase errors are measured by counting pulses of a clock signal between the arrival of a position signal related to a rotational position of the drive motor and the arrival of a reference signal.  An automatic residual error compensating circuit controls a delay applied to the position signal in accordance with residual phase error to minimize the same.

Abstract: ABSTRACT OF THE INVENTION       This invention relates to electrical aircraft engine start and generating system for use in an aircraft having an engine driven torque converter coupled to an alternator which provides AC power for conversion to DC and AC power.  The system includes a reversible AC to DC converter controllably electrically coupled to the alternator and a controller unit to provide DC power in a generating mode.  The reversible AC to DC converter is capable of receiving externally supplied DC power to be converted to AC power to drive the alternator as a motor in a start mode.   A DC to AC converter is controllably electrically coupled to the controller unit and the DC power output during the generating mode.  The reversible DC to AC converter in the start mode is mutually controllably electrically coupled to the externally supplied DC power.          The controller unit and the alternator cooperate to provide a controlled AC power output to be delivered to the alternator to bring the alternator operating as a motor up to operating speed, whereupon the reversible DC to AC converter responds to the external DC power and is electrically coupled to the alternator to drive the alternator as a motor to deliver rotary power through the torque converter to start the aircraft engine.
