Patent number: 6913460Abstract: An orthodontic coupling includes a first portion and a second portion that are resiliently interconnected for movement toward and away from each other. The second portion is adapted for insertion into a passage of an orthodontic appliance, and the resilient connection between the first portion and the second portion releasably secures the coupling in place. The coupling is particularly useful for connecting force modules such as Class II correctors to buccal tube appliances.Type: GrantFiled: June 12, 2002Date of Patent: July 5, 2005Assignee: 3M Innovative Properties CompanyInventors: James D. Cleary, John J. Palmer

Patent number: 6280185Abstract: An orthodontic appliance such as a bracket or buccal tube is made of a stainless steel alloy that includes chromium, nickel and precipitates of titanium. The alloy imparts a relatively high strength to the appliance and is resistant to corrosion. Optionally, the appliance has structural sections that are smaller than corresponding sections of comparable appliances when made of conventional stainless steel alloys used in orthodontic appliances. As a consequence, the appliance is more aesthetic when mounted on a tooth of a patient undergoing treatment.Type: GrantFiled: June 16, 2000Date of Patent: August 28, 2001Assignee: 3M Innovative Properties CompanyInventors: John J. Palmer, John S. Kelly, James D. Hansen

Patent number: 6036817Abstract: The efficiency by which pulp cooking liquor components penetrate the wood and enable lignin and resins to be removed from the cellulosic materials is increased by contacting wood chips and the like with a liquid mixture comprised of white liquor containing at least one surfactant selected from the group consisting of a polymethylalkylsiloxane; a co- and terpolymer of silicone and a polyhydric alcohol; an alkoxylated aryl phosphate; an alkoxylated branched alkyl phosphate; an alkoxylated branched alcohol; an alkyl polyglycoside, an alkoxylated alkyl polyglycoside; a mixture of alkali metal salts of alkyl aromatic sulfate, a sulfosuccinate and a silicone; and combinations thereof; for a residence time effective to extract resinous components without substantial degradation of cellulose and thereafter heating at least a portion of the resulting mixture and wood chips.Type: GrantFiled: November 17, 1997Date of Patent: March 14, 2000Assignee: Henkel CorporationInventors: Marie-Esther Saint Victor, David I. Devore, Barbara Balos Bowker, John J. Palmer, Vincent T. Stine

Patent number: 5375459Abstract: An apparatus and method is provided wherein the foam inhibiting effectiveness of defoaming and antifoaming additives on various types of foamable liquid mediums is measured. A single generally cylindrical foam cell having openings at both ends is provided wherein an interchangeable foam cell insert having varied geometry is longitudinally disposed within the foam cell. The foam cell insert is provided with a plurality of centralizer walls extending into the foam cell with an agitator member being carried by the centralizer walls. Foamable liquid medium is introduced into the foam cell and recirculated therethrough to form a dynamic fluid-flow system. As the liquid medium passes through both the foam cell and the foam cell insert, it comes into contact with the agitator member carried by the centralizer walls of the foam cell insert forming foam which accumulates in the foam cell.Type: GrantFiled: December 13, 1993Date of Patent: December 27, 1994Assignee: Henkel CorporationInventors: Richard Gerke, Jose M. Rodriguez, John J. Palmer
