Patent CA-2406127-A1 (CA)
Inventor: BROWN FRED A
IPC: H02P5/68
Filed: 2002-09-30
Abstract: A DC electric motor includes an internal programmable element that permits it to be synchronized to an external reference signal. To that end, the motor includes a rotor capable of rotating at a rotational speed, rotor circuitry that controls the rotational speed of the rotor, and an input to receive the noted external reference signal, which indicates a preset speed. In addition, the motor also includes the noted programmable element, which is operatively coupled with the input and the rotor circuitry within the motor. The programmable element is capable of comparing the external reference signal with the rotational speed of the rotor and, consequently, controls the rotor circuitry based upon the comparison of the external reference signal and the rotational speed of the rotor.

Title: Seal configuration to reduce seal extrusion
Inventor: DELBRIDGE CLAYTON
IPC: F16J15/16
Filed: 2002-11-28
Abstract: A seal configuration to reduce seal extrusion includes a body having an opening with inwardly tapered peripheral sidewalls. A closure having an attachment portion larger than the opening and an axially projecting stopper portion adapted to fit closely within the opening. The stopper portion has an endless peripheral seal groove extending in spaced relation around the axis in which is positioned a peripheral seal which conforms to the tapered peripheral sidewalls. A backing ring of pliable memory retaining material is positioned between the peripheral seal groove and the attachment portion of the closure. The backing ring resists extrusion flow under pressure. In response to an increase in internal pressure within the body, the peripheral seal is extruded against the backing ring which deforms to prevent the peripheral seal from entering the extrusion gaps.

A dual slope integrator circuit is coupleable to the probe capacitor for charging it during a first integration period and discharging it during a second integration period utilizing the first and second reference voltage potentials. The integrator circuit includes a circuit for comparing capacitive voltage generated during the first and second integration periods with the first and second reference voltage potentials to generate timing signals for each integration period. The timing signals from two successive integration periods are used for determining the capacitance of the probe transducer. A system and method of determining the probe capacitance are also disclosed.
