Title: Electronic control for an automatic washing machine with a reversing psc motor
Inventor: BASHARK LARRY THOMAS
IPC: D06F34/08
Filed: 1990-08-09
Granted: 1999-02-09
Abstract: A control for an automatic washing machine with a reversing permanent split capacitor (PSC) drive motor.          Separate ferrite core sensors surround each of two PSC motor windings.  A sense winding is threaded through both sensors.          A brief output voltage is generated whenever the alternating current in either PSC motor winding passes through a zero-crossing and when the sense winding is wound with proper mutual polarity, an output voltage is generated in response to zero-crossings of a brief, residual alternating current which flows in both PSC motor windings and the capacitor when the rotating PSC motor is cycled OFF.  The circuitry, in combination with the sensors, samples the leading or lagging phase angle of the PSC motor auxiliary or main winding, respectively, at a sample rate of two-times the line frequency when the PSC motor is ON.  The raw PSC motor phase data is used in microcomputer programs to compute motor start time or load torque dither.  This computed information and the PSC motor braking data, is used by other software programs to automatically control various functions of the washing machine such as the fill water level and agitator stroke angle; to control events in an operational sequence such as the duration of the agitation and spin operations; and to provide diagnostic information such as spin off-balance detection.

Title: Delivery catheter
Inventor: SCHATZ RICHARD A
IPC: A61B17/42
Filed: 1991-08-23
Granted: 1996-08-13
Abstract: A delivery catheter for introducing living matter into a body passageway or cavity of a female mammal comprises a hollow,  flexible,  substantially  tubular-shaped  collection chamber for holding the living matter.  An ejection port is formed adjacent to the distal end of the collection chamber and an actuator port is formed at its proximal end.  A guide tube having a lumen,  is positioned coaxially   within the collection chamber with the respective distal and proximal ends of the guide tube and the collection chamber joined together in fluid-tight sealing engagements.  In operation, the delivery catheter is inserted into the body passageway over a prepositioned guide wire.   More specifically, the delivery catheter receives the guide wire through the lumen of its guide tube to advance the delivery catheter along the guide wire.  Once the ejection port of the collection chamber is positioned at the desired site in the body passageway, fluid is introduced into the collection chamber through the actuator port to eject the living matter through the ejection port and into the body passageway.  The delivery catheter and the guide wire are then withdrawn from the passageway.

Title: Method and apparatus for visual inspection of the internal structure of apparatus through internal passages
Inventor: DAILEY GEORGE FRANKLIN
IPC: G01M99/00
Filed: 1992-08-18
Granted: 2003-10-14
Abstract: The internal structure of an apparatus with internal passages such as a steam turbine is inspected without dismantling by inserting a compact robotic carriage device into a steam pipe and remotely controlling the carriage to carry a video probe to a restricted passage such as a nozzle block and to extend the probe relative to the carriage to inspect features within the restricted passage such as turbine blades. Separate motor drives for each side of the carriage include drive wheels of slightly greater diameter than a timing belt which serves as a tractor tread to drive the carriage over obstacles not bridged by the wheels. A large permanent magnet between the wheels is retained within the carriage by front and rear axles and secures the carriage to the pipe walls in all orientations.      The fixed size of the device is minimized by housing a motor for extending the probe relative to the carriage in a module cantilevered from the carriage by a preloaded compression spring. The single plane of articulation of the video probe is rotated by a torsion cable connected to the probe lead just behind the carriage.

Title: Swivel valve
Inventor: LIND JOHN R
IPC: F16K15/20
Filed: 1992-10-21
Granted: 1996-05-07
Abstract: A swivel valve has a valve body having an elongated bore with both the valve body and the bore having first and second ends.  A gas or fluid port is located in the first end of the valve body and is in communication with the first end of the bore.

Title: Data queueing apparatus and atm cell switch based on shifting and searching
Inventor: YAMANAKA HIDEAKI
IPC: H04L12/54
Filed: 1994-02-03
Granted: 2000-08-01
Abstract: A data queueing apparatus processes data switching and queueing using a smaller capacity memory, while reducing data discard and loss possibility. Received limited-length data at the input line is written in shift memories, which can shift the data to the next stage regardless of the destination of the data. Destination indicating bits, which indicate the destination of the data, are associated with each of shift memories. A search circuit detects an asserted bit among the destination indicating bits corresponding to the output lines. The data is extracted by a selector. Then the selector transmits the data to the desired output line, and the data stored in the previous stage of the shift memory is shifted.      The memory is used in common with a plurality of output lines, so that a lower possibility of data discard and loss can be attained in a smaller capacity memory.
