Title: Apparatus and methods for controlling induction motors
Inventor: UNSWORTH PETER J
IPC: H02P27/02
Filed: 1981-09-25
Granted: 1985-12-31
Abstract: ABSTRACT    When induction motors are lightly loaded their power factors and efficiency are poor but in the present invention power factor is controlled regardless of load.  An induction motor is connected by way of a triac to a supply.  The voltage across the triac is monitored by a comparator for voltage steps which correspond to current turn-off and a signal is developed at the output of an amplifier which represents error from required phase lag.  A further comparator and a trigger pulse generator trigger the triac in accordance with the error.  An override circuit overrides the control system during starting.  A number of further induction motors may be connected in parallel with the motor.  Additional circuits deal with problems arising when a three-phase induction motor is connected by three wires only.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention contemplates an improved sandwich-type core construction for a heat exchanger, featuring light weight without sacrifice of the strength needed for handling elevated pressures.  Passages of one set are interleaved with those of another set, using spaced parallel heat-transfer plates.  Elongate parallel spacers extending in one direction establish, with their adjacent plates, flow passages of one system, while elongate parallel spacers extending in a different direction establish flow passage of a second-system, between paired plates of the first-system.     The perimeter of the core at ends of the second-system passages establishes solid continuous seating for second-system headers.  Substantial weight saving, without sacrifice of strength, is achieved by depressed excavation of spacer material in regions thereof not involved in header-seating accommodation.

Abstract: Abstract Of The Disclosure A clutch and brake system for starting and stopping a power press uses hydraulically actuated brake and clutch mechanisms.  To start the press, the brake is hydraulically released while the clutch is hydraulically engaged at a predetermined intermediate torque level which is less than the full clutch torque level.  The clutch is maintained at that intermediate torque level until the present drive shaft has attained its substantially full speed, and is then increased to the full clutch torque level.  To stop the press, the clutch is hydraulically disengaged while the brake is hydraulically engaged at a predetermined intermediate torque level which is less than the full brake torque level.  The brake is maintained at this intermediate torque level until the press drive shaft has substantially stopped, at which time the brake torque is increased to the full brake torque level.

Abstract: Abstract Of The Disclosure __ A contact operating mechanism  is disclosed which employs a hydraulic motor means for moving contact members between  closed  and  tripped  positions,  an  accumulator  for supplying hydraulic fluid under pressure to the motor means, and a separate gas supply means in fluid communication with the  accumulator.    The  accumulator  includes  a  piston  or separating means for dividing the interior of the accumulator into two separate pressure chambers.   One of the pressure chambers is connected to the hydraulic motor means and the other is connected to the gas supply means.  Preferably, the gas supply means is separately disposed from and permanently connected  to the  accumulator  with  a  sufficient  volume  of pressurized  gas  such  that  in  the  event  that  the  piston repositions so as to completely fill  the accumulator with hydraulic fluid sufficient gas under pressure is available to stroke the accumulator piston and operate the motor means.  A pressure indicating means, such as a pressure activated switch or gage, when connected to the gas supply means provides a means of monitoring minimum gas energy even if the accumulator should completely fill with hydraulic fluid.

Abstract: ABSTRACT OF THE DISCLOSURE       A system is provided for filtering and demodulating digital color mixture signals, wherein the signals are filtered to remove out-of-band noise prior to completion of the demodulation process.  Interleaved digital chrominance signal samples are first demodulated by a signal related in frequency to the video subcarrier to obtain interleaved color mixture signal samples of different sampling phases at baseband frequencies.  The interleaved color mixture signal samples are applied to a digital filter at a rate which is a multiple of the color subcarrier frequency.  The weighting coefficients of the filter are selected to obtain a bandwidth which passes the color mixture signal while removing out of band noise. Since the input signal sequence to the digital filter contains interleaved color mixture signal samples, alternate stages of the filter shift register are tapped, so that the output sequence will comprise filtered and interleaved color mixture signal samples.  An output sampling switch accomplishes phase demodulation of the output sequence by selecting samples at a reduced sampling rate in accordance with the Nyquist criterion of the color signals and produces either one or two output sequences of filtered and fully demodulated color mixture signals. Tapped shift register stages of the digital filter may be coupled to two different sets of weighting coefficients and signal combining stages.  The filter outputs may thus exhibit unequal bandwidths for filtered color mixture signals, which are commensurate with the desired bandwidths of the filtered signals.
