Patent number: 9084764Abstract: In one aspect, an epidermal coolant includes a porous material and a phase change material retained in the porous material. The phase change material has a melting point between about 0-degrees Celsius and about 65-degrees Celsius and is retained in the porous material when the phase change material is in either the solid or liquid phase. In another aspect, an epidermal coolant dispensable by an aerosol container includes a phase change material that changes phase between about 28-degrees and 40-degrees Celsius. The coolant also includes a solvent in which the phase change material is dissolved and a surfactant. The coolant may further include a propellant to express the product from the aerosol container.Type: GrantFiled: August 16, 2012Date of Patent: July 21, 2015Assignee: Exert Co.Inventor: Arvind M. Rao

Patent number: 6997404Abstract: An improved filter assembly for a solenoid-actuated fuel injector having a fuel-resistant porous filter element in a filter retainer tube for disposition in the fuel tube of the fuel injector. Fuel flow through the filter element is axial. The filter retainer tube replaces the calibration tube in a prior art fuel injector, also acting as a seat for the injector spring and being positioned axially within the fuel tube by a press-fit calibration ring. The retainer tube is preferably formed of glass-filled nylon, and the filter element is preferably formed by injection molding of an open-cell polyamide foam. By selecting the porosity and flow characteristics of the filter element material in known fashion, the length and diameter of the filter element may be minimized, permitting reduction in the length and diameter of the fuel tube and also the size and cost of the actuating solenoid assembly.Type: GrantFiled: June 12, 2002Date of Patent: February 14, 2006Assignee: Delphi Technologies, Inc.Inventor: Arvind M. Rao

Publication number: 20040013916Abstract: A corrosion-resistant electrochemical device includes a plurality of fuel cells connected in electrical series, each fuel cell having a membrane-electrode-assembly comprising an anode catalyst layer and an anode diffusion layer disposed on one side of an electrolyte membrane and a cathode catalyst layer and cathode diffusion layer disposed on an opposite side of the electrolyte membrane; at least one bipolar plate disposed between adjacent fuel cells; and at least one neutralization agent or ion exchange media sufficient to neutralize corrosive species in fuel cell effluent in situ disposed within the device. The neutralization agent may be disposed in one or more locations including in flow channels of the bipolar plate, embedded within diffusion layers of the MEA, disposed in combination with the catalyst layers on the electrolyte membrane, and as an integral part of the material comprising the bipolar plate itself.Type: ApplicationFiled: July 18, 2002Publication date: January 22, 2004Inventors: Arvind M.
