Publication number: 20030119917Abstract: The present invention relates to a dispersible silicone composition comprising a blend of (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, and (iii) a catalytic amount of a compound for promoting the reaction of the other components and (II) a polyisobutylene compound. The polyisobutylene oligomer or polyisobutylene polymer is effective as a dispersing agent for the silicone composition (I). The polyisobutylene-containing compositions are easier to handle, produce less waste, and their dispersion into mineral oil formulations is more efficient.Type: ApplicationFiled: September 27, 2002Publication date: June 26, 2003Inventors: Kenneth Christopher Fey, James Habermehl

Patent number: 5977191Abstract: The present invention relates to a method for controlling foam in a foam producing system comprising adding to the foam producing system a dispersible silicone composition comprising (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, optionally (iii) a finely divided filler, and (iv) a catalytic amount of a compound for promoting the reaction of the other components and (II) a hydrocarbon oil. The hydrocarbon oil is effective as a dispersing agent for the silicone composition (I). The hydrocarbon oil-containing compositions are easier to handle, and produce less waste and its dispersion into mineral oil based formulations is more efficient.Type: GrantFiled: January 22, 1999Date of Patent: November 2, 1999Assignee: Dow Corning CorporationInventors: Kenneth Christopher Fey, James Habermehl

Patent number: 5914362Abstract: A silicone-based antifoam composition, in the form of an emulsion, is prepared from the reaction of (A) a primary silicone composition and (B) a polydiorganosiloxane having condensable terminal groups in a nonpolar organic medium selected from the group consisting of polyisobutylene and mineral oil. The reaction of the primary silicone composition (A) and the polydiorganosiloxane (B) produces a secondary silicone composition, which forms the discontinuous phase of the emulsion and the nonpolar organic medium forms the continuous phase of the emulsion. The resulting composition of the invention exhibits antifoam efficacy greater than that of the primary silicone composition.Type: GrantFiled: October 30, 1997Date of Patent: June 22, 1999Assignee: Dow Corning CorporationInventors: Doris Jean Brecht, Russell Allen Elms, Kenneth Christopher Fey, Ronald Paul Gee

Patent number: 5801893Abstract: A method for adaptively detecting when portion of a magnetic tape is wrapped around a capstan of a magnetic tape cassette player includes the steps of transferring the magnetic tape from a supply reel to a take-up reel for a first rotation of the take-up reel, passing the magnetic tape across the capstan when the magnetic tape is being transferred, measuring a first set of pulses of a signal during the first rotation of the take-up reel, measuring a subsequent set of pulses during each subsequent set of a take-up reel, and stopping the rotation of the take-up reel when the subsequent set of pulses varies from the subsequent of pulses immediately proceeding to prevent the magnetic tape from wrapping around the capstan.Type: GrantFiled: July 1, 1996Date of Patent: September 1, 1998Assignee: Ford Motor CompanyInventors: Kenneth Christopher Miller, Max Cannon Chapman, Daniel Thomas Donaldson
