Patent number: 6851622Abstract: A fuel injector for use with an internal combustion engine. The fuel injector can include a tube assembly, an armature assembly, a working air gap, a coil, and a housing. The tube assembly has a longitudinal axis and includes a non-magnetic tube having a first end and a second end, and a pole piece disposed inside the non-magnetic tube intermediate the first and second ends. The armature assembly is disposed within the tube assembly between the pole piece and the first end. The armature assembly includes an end face resiliently biased away from the pole piece. The working air gap separates the end face and the pole piece when the end face is biased away from the pole piece. The coil is connectable to an electrical power source and operable to displace the end face toward the pole piece against the resilient bias on the armature assembly. The housing is positioned adjacent the working air gap and supports the coil on the tube assembly.Type: GrantFiled: January 8, 2002Date of Patent: February 8, 2005Assignee: Siemens VDO Automotive CorporationInventors: Sims B. Deméré, Robert McFarland, Dennis Bulgatz

Publication number: 20040188045Abstract: Disclosed is a composition for softening a wet laid cellulosic structure. A particularly preferred structure is an absorbent tissue. Further disclosed are tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone.Type: ApplicationFiled: January 28, 2004Publication date: September 30, 2004Applicant: The Procter & Gamble CompanyInventors: David D. McKay, John Ernest Rice, Kenneth Douglas Vinson, James Robert McFarland, Amy Jo Hamilton, Errol Hoffman Wahl, Gayle Marie Frankenbach
