Publication number: 20150114654Abstract: A tool for polishing a seal surface of a wellhead assembly includes a cylindrical tool body with an axis. The tool body includes a base member with a first end, and a second end. A tubular skirt member extends from the second end of the base member. The skirt member has a sidewall, a base end connected to the base member, and an open end opposite the base end. A plurality of axial slots extend through the sidewall of the skirt member, the axial slots being spaced circumferentially around the skirt member. A polishing belt is woven through the axial slots of the skirt member.Type: ApplicationFiled: October 30, 2013Publication date: April 30, 2015Applicant: GE Oil & Gas Pressure Control LPInventors: Noel Anthony Monjure, Eugene Allen Borak, Andrew Browne Helvenston

Publication number: 20140352977Abstract: A tool for retaining an activator ring of a hanger within a wellhead assembly during a fluid pumping process includes an annular fluid pumping sub body having an end selectively coupled with a supply of fluids and a distal end selectively coupled with the hanger. An outer ring assembly circumscribes and rotates relative to the fluid pumping sub body. A retainer ring circumscribes the fluid pumping sub body and selectively abuts the activator ring. A plurality of biasing assemblies that are selectively compressible are located between the outer ring assembly and the retainer ring, so that when the fluid pumping sub body is coupled with the hanger, an axial lockdown force is maintained on the activator ring by the biasing assemblies during the fluid pumping process.Type: ApplicationFiled: March 4, 2014Publication date: December 4, 2014Applicant: GE OIL & GAS PRESSURE CONTROL LPInventors: Eugene Allen Borak, Jr., Gajanan B. Hegde, Andrew Browne Helvenston

Patent number: 8162646Abstract: In an apparatus and process for manufacturing a detergent bar, the bar comprises a first distinct zone comprising a first component and at least a second distinct zone comprising a second component. In an injection step, the first and second components are injected into the mould cavity via nozzle means having a first orifice through which the first component is injected. The second component is injected through a second orifice of the nozzle means. The first and second components solidify in the cavity to form the bar. The interface between the zones may be non-planar and/or such that the zones cannot be separated by a unidirectional cut. The first and second zones may respectively comprise detergent and a benefit agent. The first and second zones may differ in texture.Type: GrantFiled: November 19, 2009Date of Patent: April 24, 2012Assignee: Conopco, Inc.Inventors: Michael Andrew Browne, Paul Lloyd, Sudhir Mani, Christine Ann Overton, Frederick Edmund Stocker

Patent number: 6703005Abstract: A deodorant or antiperspirant soft solid composition is filled into dispensing containers by injection moulding, i.e. under pressure, preferably in the vicinity of its normal setting temperature. The deodorant or antiperspirant composition is preferably continuously produced in a screw extruder, especially a twin screw extruder, controlled to deliver the composition in a suitably viscous state under low shear and particularly for formulations in which a particulate antiperspirant is suspended in a fluid carrier. The pressure in the injection head at the point of injection is greater than 120 kPa and in many instances from 800 to 2000 kPa. The combined process offers benefits for controlled fill of dispensing containers, particularly for formulations incorporating sensitive ingredients and offers tolerance in composition temperature at the time of fill.Type: GrantFiled: April 5, 2001Date of Patent: March 9, 2004Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Peter Stewart Allan, Michael Andrew Browne, Elfriede Maria Langeveld, Paul Lloyd, Reginald Manley, Paul Reissen Rennie, Frederick Edmund Stocker, Karnik Tarverdi, Jacqueline Marie Thorpe

Patent number: 6338840Abstract: In a first aspect, a process for forming deodorant or antiperspirant sticks by continuously forming a mobile composition for dispensing into containers or molds at a rate matched with the rate at which it is dispensed, and in other aspects a process in which a mobile deodorant or antiperspirant composition is dispensed by injection molding, i.e. a process in which the deodorant or antiperspirant composition is dispensed under pressure. The composition at the time of injection moulding is preferably either in the vicinity of its regular set temperature, particularly in the range of about 0-3° C. below the regular set temperature and/or partially structured at the time of its delivery it into a container or mold.Type: GrantFiled: October 6, 1999Date of Patent: January 15, 2002Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Peter Stewart Allan, Elaine Susanne Bibby, Michael Andrew Browne, Elfriede Maria Langeveld, Paul Lloyd, Reginald Manley, Robert J Owen, Paul Riessen Rennie, Jean Lesley Scott, Frederick Edmund Stocker, Karnik Tarverdi, Jacqueline Maria Thorpe
