Patent number: 5192197Abstract: An electric pump comprises a housing (22) that encloses a stack of waveplates (18) in which electrically created traveling waves forcefully move fluid (20) from an inlet duct (24) to an outlet duct (26). Each waveplate is made of shear type transducer material that is segmented by film electrodes, the electrode planes lying perpendicular to the direction of fluid flow. Electrode sets are stimulated by a multiphase electrical power source. The pressure at wave crest contacts is electrically controlled to hermetically trap fluid portions between waves, thereby achieving high throughput against high pressure differential. Rubbing is essentially absent throughout the pump, life shortening mechanisms being few and benign. High electromechanical efficiency obtains when waveplates are stimulated by electrically resonant frequencies. Pump variants include variable wavelength, variable wave amplitude, and tapered waveplates for improved effectiveness with compressible fluids.Type: GrantFiled: November 27, 1991Date of Patent: March 9, 1993Assignee: Rockwell International CorporationInventor: Gordon W. Culp

Patent number: 5182484Abstract: The present invention is useful for quickly releasing an object which is being moved by an actuator. Generally actuators of the piezoelectric type move objects slowly. For applications where an object must be quickly moved such as when releasing brakes or reinserting a control rod in a reactor core an actuator should have a quick release feature. The invention uses a set of actuators which contact a bolt and moves the bolt with smooth walking motion. The bolt in turn is driven by the actuators such that it engages an object with smooth walking motion to move or position the object. When the object is to be released the actuators are removed from contact from the bolt thereby releasing the object.Type: GrantFiled: June 10, 1991Date of Patent: January 26, 1993Assignee: Rockwell International CorporationInventor: Gordon W. Culp
