Patents by Inventor Winston F. Z. Lee

Winston F. Z. Lee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Self-correcting self-checking turbine meter
    Patent number: 4305281
    Abstract: A turbine meter is disclosed in which a sensing rotor downstream from the metering rotor senses changes in the exit angle of the fluid leaving the metering rotor, the output from the sensing rotor being combined with the output from the metering rotor to produce a corrected output indicative of the flow of fluid through the meter. The output from the sensing rotor and the output from the metering rotor may be compared to provide an indication of deviation from performance at calibration.
    Type: Grant
    Filed: June 4, 1979
    Date of Patent: December 15, 1981
    Assignee: Rockwell International Corporation
    Inventors: Winston F. Z. Lee, Raymond V. White, Felice M. Sciulli, Andrew Charwat
  • Constant accuracy turbine meter
    Patent number: 4286471
    Abstract: A turbine meter is disclosed in which a sensing rotor downstream from the metering rotor senses changes in the exit angle of the fluid leaving the metering rotor, the output from the sensing rotor being combined with the output from the metering rotor to produce a corrected output indicative of the flow of fluid through the meter. The output from the sensing rotor is utilized through a closed loop feed back system to modify the operation of the metering rotor in accordance with variations in the exit angle of the fluid leaving the metering rotor.

    Inventors: Winston F. Z. Lee, Raymond V. White, Felice M. Sciulli
  • Turbine meter in-line checking apparatus and method
    Patent number: 4091653
    Abstract: This invention discloses apparatus and method for checking the calibration of a fluid turbine meter without interrupting the line service. A flow directions sensing means is inserted at the downstream side of the flowmeter so that the angle of flow the discharge from the meter may be checked from time to time without removing the meter from its flow line. Any change in this angle indicates a possible change in response of the meter.

  • Permanent magnet electrical machines
    Patent number: 3978354
    Abstract: Electrical machines comprising a rotatable armature and permanent magnets surrounding and separated from the armature by air gaps having a length to width ratio not greater than 60:1 and a minimum width of 0.040 inch irrespective of the length to width ratio, thereby allowing cooling air to be circulated through the air gaps as well as through the annular gaps between the magnets. Such machines have a substantially higher steady state power output than permanent magnet machines of the same overall dimensions designed in accord with conventional techniques because of materially improved armature cooling.
