Patent number: 8176747Abstract: A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g., ?80° C.) storage and retrieval systems which stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are loaded into trays located within an ultra-low temperature freezer compartment (?80° C.). A tube picking mechanism resides in a tube picking chamber that is located adjacent the freezer compartment. The tube picking chamber is maintained at about ?20° C. when the tube picking mechanism is in operation. The tube picking mechanism includes a cache within the tube picking chamber to facilitate fast paced shuttling of the tube racks from the freezer compartment into the tube picking chamber. The shuttle has a clamping mechanism to secure a tube rack in place when a gripper head picks a tube from the rack. The system also includes a push pin that pushes on the bottom of the respective tube as it is being picked from the tube rack.Type: GrantFiled: July 31, 2008Date of Patent: May 15, 2012Assignee: Hamilton Storage Technologies, Inc.Inventors: Raymond T. Howard, Julian Warhurst, Behrouz Zandi, Michael A. Carman, James O'Toole

Patent number: 7282832Abstract: A superconducting rotating machine includes a stator assembly having at least one stator coil assembly. A rotor assembly, which includes an axial shaft, is configured to rotate within the stator assembly. The rotor assembly includes at least one superconducting winding assembly. A first and second end plate are rigidly attached to the axial shaft at distal ends of the at least one superconducting winding assembly. An asynchronous field filtering shield surrounds the at least one superconducting winding assembly. A first interconnection assembly connects the shield to the first end plate. The first interconnection assembly allows for axial movement between the shield and the first end plate but restricts tangential movement between the same.Type: GrantFiled: September 19, 2001Date of Patent: October 16, 2007Assignee: American Superconductor CorporationInventor: Raymond T.
