Patent number: 7909828Abstract: An acetabular reamer (10?) for cutting a required cut shape. The reamer has a cutting shell (12?) having a series of doubly curved cutting teeth (16?) thereon of a quantity to substantially reduce a cutting pressure on each tooth as well as to reduce a size of a typical chip generated upon cutting.

Patent number: 7882622Abstract: An apparatus and method for fabricating continuous cathode collecters for use in lithium/thionyl chloride and lithium/sulfuryl chloride cells is described. The preferred electrically conductive material is acetylene black mixed with a polytetrafluroethylene (PTFE) binder in a dry, powderized form. The collector substrate is a nickel or stainless steel foil that has been expanded into a mesh or otherwise provided with perforations. A centering adjustment of the collector substrate controls loading of the electrically conductive mixture onto each side thereof. The dry, powdered electrically conductive mixture is then continuously fed into the calender and formed into a collector structure by locking to itself through the collector substrate perforations before being cut to size.Type: GrantFiled: December 22, 2006Date of Patent: February 8, 2011Assignee: Electrochem Solutions, Inc.Inventors: Peter Polsonetti, Mihai Albu, Moazzam Aziz, Robert Yetman, Douglas Woodnorth

Patent number: 7855009Abstract: A new design for a cathode having a configuration of: SVO/first current collector/CFx/second current collector/SVO is described. The two cathode current collectors are vertically aligned one on top of the other in a middle region or zone of the cathode. This coincides to where a winding mandrel will be positioned to form a wound electrode assembly with an anode. The overlapping region of the two current collectors helps balance the expansion forces of the exemplary SVO and CFx active material layers. This, in turn, helps maintain a planar cathode that is more amenable to downstream processing. The use of two current collectors on opposite sides of an intermediate cathode active material also provides for enhanced reliability when cathodes are wound from the center as they lend structural integrity to outer portions of the wind.Type: GrantFiled: September 15, 2006Date of Patent: December 21, 2010Assignee: Greatbatch Ltd.Inventors: Robert S Rubino, Hong Gan, Esther S Takeuchi
