Patent CA-2129335-C (CA)
Inventor: HARRIS WILLIAM A
IPC: H02P29/02
Filed: 1993-04-20
Granted: 2003-03-11
Abstract: A circuit arrangement is provided to mitigate the parasitic capac-itance that typically is associated with solid state switches which are de-signed to carry high current magnitudes. By disposing a capacitive com-ponent in series with a power switch which, in turn, is connected in series with an inductive component, the overall capacitance of the switch and capacitive component are significantly reduced. In a preferred em-bodiment of the present invention, the capacitive component is a diode with a voltage potential provided at the cathode of the diode so that the parasitic capacitance of the diode can be varied to tune the total circuit for the purpose of achieving a specific resonant frequency. In applica-tions where high frequency signals are injected into the circuit for pur-poses of measuring a parameter, such as rotor position, the present in-vention is beneficial because of the ability to tune the frequency resulting from the residence of the series LC circuit which comprises a conductive component, such as a motor stator winding; and a capacitive compo-nent,such as a power switch which possesses an inherent parasitic cap-acitance. Another benefit of the present ivention is the fact that it makes possible the use of smaller components in a snubber network associated with the inductive component because of the increase in resonant fre-quency achieved by the decrease in capacitance of the series LC circuit.

Abstract: A  downhole  pump comprises  a  pump  cylinder  driven  by  a pneumatic cylinder.   A compressor compresses air and delivers compressed air to the pneumatic cylinder under the control of first and second trip valves and a pilot valve.  The trip valves control the pilot valve so that it alternately delivers the compressed air above and below the pneumatic cylinder piston to reciprocally drive the piston.  The pneumatic cylinder piston connects to the pump cylinder via a pair of push rods to drive the pump cylinder piston to pump water from the well to an above-ground reservoir.

Abstract: There is disclosed an interactive information processing system and a method of processing information interactively using a computer. In one aspect, a communication manager is interposed between a common platform having a plurality of windows and an extensible Window-based Elaboration Language (WELL) system. The communication manager uses a template to convert data between a visible object rendered in the common platform and a data structure discernible by a computer. An extensible WELL kernel activates a required service module in response to an instruction entered by a user through the common platform and transmitted via the communication manager. In a second aspect, an agent-role server having the foregoing configuration is installed as a client of specific role servers each having the foregoing configuration. This interactive information processing system finds utility where transactions are visually rendered in the form of object networks.

Abstract: An oil management system for a refrigeration system having a screw compressor for pressurizing and circulating refrigerant through the system and an evaporator having a shell enclosing a chamber for allowing phase change of the refrigerant.   A suction line is provided to fluidly connect the evaporator chamber to the inlet side of the compressor.  The suction line is sealed about an opening in the shell and has a distal end projecting into the chamber below the seal.  A reservoir is positioned within the chamber, below the suction line.   The reservoir is employed for collecting lubrication oil migrating down the suction line during low load operation of the compressor so that when the level of oil in the reservoir reaches a predetermined level, the opening in the distal end of the line  will  be  restricted  thereby  increasing  the  flow velocity proximate thereto causing reintroduction of the oil into the compressor.

Abstract: The present application makes use of a novel adaptive noise-predictive parti al-response equalization scheme for channels (30) exhibiting spectral nulls and/or near nulls. The noise-predictive partial re sponse (PR) equalizer employed in the different embodime nts of the present invention consists of a linear PR equalizer (32) which shapes  the channel response to a predetermined partial-respons e function, followed by a linear predictor. This scheme modifies the output se quence of said linear partial-response equalizer (32) by whitening the total distortion, i.e. by whitening the noise components and t he residual interference components at said linear PR eq ualizer output, thereby achieving the best possible signal-to-noise ratio (SNR) befo re detection.

Granted: 2000-09-19
Abstract: abstract For monitoring a predetermined level of a liquid in a container an ultrasonic transducer is fitted on the outer surface of the container wall at a measurement point situated at the height of the level to be monitored. The ultrasonic transducer contains a piezoelectric  element  which  generates,  when  excited  by  an alternating  voltage  pulse  having  a  given  transmission frequency,  an ultrasonic transmission pulse which is trans-ferred via a diaphragm to the container wall and which converts ultrasonic vibrations transferred from the container wall to the ultrasonic transducer into electrical reception signals. So that the piezoelectric element for given dimensions can be operated  in  a  large  frequency  range,  and  so  that  a  good adaptation to the diaphragm  is  achieved,  the piezoelectric element consists of a porous piezoelectric ceramic having a type 3-3 connectivity.
