Patent number: 11661938Abstract: Systems and methods are provided for pumps that deliver optimized torque characteristics and volumetric efficiency. A system includes a housing defining a surface and a rotor defining a face. A face clearance is defined between the face and the surface. The face clearance is variable in magnitude and determinative of target performance characteristics of the pump system. The housing is made of a material selected to have a thermal expansion characteristic and the rotor is made of a second material selected to have another thermal expansion characteristic. The thermal expansion characteristics deliver the target performance characteristics of the pump system.Type: GrantFiled: August 31, 2021Date of Patent: May 30, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Robert Benson Parrish, Michael P Fannin, Avinash Singh, Ryan David Rosinski, Alan Clifford Taylor, Thomas John Fonville

Publication number: 20080053628Abstract: A high R-rating window assembly storing multiple, reciprocating reflective flexible film layers defined by one or more parallel, displaced films or looped films define the layers. The layers are contained in a sealed housing between rigid transparent (e.g. glazed) layers. The glazed layers are separated on the order of 3 to 5-inches and are secured to low thermal conductivity framework pieces. The framework is capped with a motorized roller and film housing and the assembly is evacuated and filled with a desiccated, inert dry gas. Several plastic, reflective coated films are supported under tension in planar parallel relation between the glazing layers from the motorized roller and several guide rollers and guide tracks. Location sensors responsive to indicia on the films identify film position. Temperature sensors monitor ambient, internal and user set thermal conditions to control film exposure.Type: ApplicationFiled: October 16, 2007Publication date: March 6, 2008Inventors: Donald Anderson, Clifford Taylor
