Patent number: 7021905Abstract: A fluid pump integrated with a motor, a fluid pump/generator device, a rotor for a fluid pump/generator device, a stator for a fluid pump/generator device and a method for pumping fluid are disclosed. Specifically, a fluid pump includes a motor rotor having a plurality of magnetic vanes that electromagnetically interact with a plurality of magnetic poles of the motor stator such that the rotor functions simultaneously as the impeller for the pump and rotor for the motor, with fluid flowing through channels on the rotor. Pump and motor are tightly integrated into one single device so that the number of parts is reduced, total size is compressed, reliability of the device is improved, and cost efficiency is increased. In addition, the use of magnetic vanes for propelling fluid improves motor efficiency. Further, the fluid flow is used to directly cool the pump/generator device, which reduces energy consumption.Type: GrantFiled: November 6, 2003Date of Patent: April 4, 2006Assignee: Advanced Energy Conversion, LLCInventors: David A. Torrey, Edward C. Kirchner

Patent number: 7014779Abstract: A vacuum separation, transport and collection system for immiscible liquids includes a separator (12) for separating two immiscible liquids such as oil and a water-based coolant, and for directing the separated immiscible liquid into a holder (16). A collector (18) is secured through a vacuum line (20) with the holder (16) and a vacuum generator (22) applies a vacuum to the collector (18) and holder (16). A controller (28) controls the vacuum generator (22) to apply a vacuum to the collector (18) and the holder (16) for a predetermined vacuum duty cycle for periodically removing separated immiscible liquid (26) from the holder (16) into the collector (18). Contaminants in the immiscible liquid cannot degrade performance of the system because such contaminants do not contact the vacuum generator (22) or controller (28).Type: GrantFiled: March 16, 2004Date of Patent: March 21, 2006Inventor: Edward C.

Patent number: 4625926Abstract: An improved multiple disk refiner of the type employing a rotatable hub which is mounted for rotation within a housing, and a plurality of spaced refiner rotor disks and additional disks in interleaved relation with each other and defining passages through which a stock suspension to be refined can be passed. Relative rotational movement occurs between the rotor disks and the additional disks. The invention is particularly concerned with an improved rotor structure which is mounted on the hub for rotation therewith, and resilient coupling means which connect the rotor with the rotor disks. The coupling means include a resiliently deformable elastomer which is arranged to deform in a shearing mode thereby permitting increased axial deflection of the rotors and operation at a higher intensity level.Type: GrantFiled: November 8, 1984Date of Patent: December 2, 1986Assignee: Beloit CorporationInventor: Edward C.
