Induction Motor Control System
US Patent:
4950970, Aug 21, 1990
Filed:
Mar 14, 1986
Appl. No.:
6/840476
Inventors:
Ray E. Davis - Old Lyme CT
Michael J. Westkamper - Oakdale CT
Earle J. Timothy - Clinton CT
Richard H. Johnson - Ivoryton CT

Assignee:
Chesebrough-Pond's Inc. - Greenwich CT
International Classification:
H02P 540
US Classification:
318809
Abstract:
An improved induction motor control system. Single-phase and three-phase AC induction motors are controlled in accordance with the equation y=m=x+b, where y is the phase angle, m is the slop, x is the firing delay and b is the offset. Subsequently, the firing delay is increased by predetermined amounts, the behavior of the phase angle is evaluated for several cycles, and the motor is controlled based on the results of the evaluation, thereby minimizing energy consumption.
Pivotally Linked Position Control Drive System
US Patent:
5735173, Apr 7, 1998
Filed:
Oct 4, 1995
Appl. No.:
8/538929
Inventors:
Ronald W. Parker - Clinton CT
Assignee:
Probot Incorporated - Branford CT
International Classification:
F16H 2702
US Classification:
74 89
Abstract:
There is provided a position control drive system having first and second drive units linked together and travelling on parallel running rails. A passive unit riding on a third parallel running rail is pivotally linked to one of the drive units. The pivoting link allows movement of the drive units longitudinally along the rails, but prevents movement in other directions. The pivot compensates for positional differences between the electronic positional control of the drive units and the mechanical linkage preventing the inefficiency in the electronic system, stresses in the mechanical system and, in severe cases, binding of the drive units to the rails.
Non-Contact Plasma Probe For Testing Electrical Continuity Of Printed Wire Boards
US Patent:
6118285, Sep 12, 2000
Filed:
Mar 6, 1998
Appl. No.:
9/036341

Assignee:
Probot, Inc - Branford CT
International Classification:
G01R 31302
US Classification:
324750
Abstract:
A system for testing the electrical conductivity of printed traces, on multiple surfaces, of a printed wiring board using non-contacting probes. The non-contact probes generate a plasma in a plasma generating chamber that is used to apply a voltage to the printed wiring board. A measurement circuit determines the magnitude of the voltage on the printed wiring board.
