Patent number: 9322678Abstract: A wireless pressure sensor comprising a protective covering positionable over the sensor's antenna portion is described. The protective covering comprises a body having an annular sidewall that extends from a proximal end to a distal end and is composed of a fluoroelastomer material. A cavity resides within the body extending through the proximal end to a distal end sidewall positioned perpendicular to the annular sidewall. The protective covering further comprises at least one annular recess intermediate at least two annular ridges that reside along an interior surface at the proximal end of the covering. These series of annular ridges and recesses form a removably tight seal around the exterior surface of the sensor that minimizes the migration of corrosive gases and fluids to the exterior surface of the sensor.Type: GrantFiled: June 10, 2013Date of Patent: April 26, 2016Assignee: Electrochem Solutions, Inc.Inventors: James K.

Patent number: 7531271Abstract: A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell and defining a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises a single plastic frame or two separate plastic frames housing the anode and cathode material. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.Type: GrantFiled: August 9, 2004Date of Patent: May 12, 2009Assignee: The Gillette CompanyInventors: Jonathan M.

Patent number: 7481851Abstract: A method of forming an anode comprising zinc for an alkaline cell. The method involves mixing zinc particles with binders including preferably polyvinylalcohol, surfactant and water to form a wet paste. The wet paste is molded into the near shape of the cell's anode cavity and then heated to evaporate water. A solid porous zinc mass is formed having microscopic void spaces between the zinc particles. The solid mass can be inserted into the cell's anode cavity and aqueous alkaline electrolyte, preferably comprising potassium hydroxide, then added. The solid mass absorbs the aqueous electrolyte and expands to fill the anode cavity to form the final fresh anode. Zinc fibers may be added to increase the structural integrity of the solid mass.Type: GrantFiled: October 15, 2004Date of Patent: January 27, 2009Assignee: The Gillette CompanyInventors: Thomas C. Richards, George Cintra, Andrew G. Gilicinski, Zhiping Jiang, C. Robert Parent

Patent number: 7179310Abstract: A method of forming an anode comprising zinc for a zinc/air cell. The method involves mixing zinc particles with binders including preferably polyvinylalcohol, surfactant and water to form a wet paste. The wet paste is compacted and molded into the near shape of the cell's anode cavity and then heated to evaporate water.
