Patent number: 8025193Abstract: A rifle holder device for supporting a rifle in a position that is easy to grab for taking a shot is described. The holder device lets a hunter or shooting enthusiast carry a rifle with its weight supported on either his right or left hip. Rifles are rather heavy weapons. Should the hunter or shooting enthusiast carry one in his hands or arms for an extended period of time, his muscles can get fatigued. This makes it more difficult to get off an accurate shot in a timely manner. However, the present holder device puts most of the rifle's weight on the hunter's hip, thereby freeing his hands and arms from having to carry the rifle until it's time to take a shoot. Further, the present holder device is adjustable for carrying rifles of many different sizes.Type: GrantFiled: June 1, 2009Date of Patent: September 27, 2011Assignee: Globe Industries, Inc.Inventor: Robert Douglas Gornall, Jr.

Patent number: 7939199Abstract: An electrochemical cell comprising a lithium anode, a silver vanadium oxide cathode having a relatively lower basis weight, and an electrolyte activating the anode and the cathode is described. By limiting the amount of cathode active material per unit area (i.e. basis weight) facing the anode in the Li/SVO cell, the magnitude of the passivating film growth at the solid-electrolyte interphase (SEI) and its relative impermeability to lithium ion diffusion is reduced. Therefore, by using a cathode of a relatively low basis weight active material, it is possible to eliminate or significantly reduce undesirable irreversible Rdc growth and voltage delay in the cell and to extend its useful life in an implantable medical device.Type: GrantFiled: April 17, 2007Date of Patent: May 10, 2011Assignee: Greatbatch Ltd.Inventors: Hong Gan, Joseph M.
