Patent number: 6061950Abstract: A burnable coil holder such as a mosquito coil holder has a base member with a plurality of non-metallic support peaks and a higher central metal support spade. The spade supports the burnable coil from a single point under normal circumstances. The non-metallic support peaks provide support if the coil sags during use. The support peaks are positioned in a cross or spiral array around the spade. The spade has teeth to grip the coil, a shoulder to support the coil, and spaced legs to permit easy insertion of the spade into the base member.Type: GrantFiled: July 2, 1998Date of Patent: May 16, 2000Assignee: S. C. Johnson & Son, Inc.Inventors: Michael R. Carey, Paul E. Furner, Donald W. Hildebrandt, Amelia H. Majerowski, Russell H. Petersen

Patent number: 6054067Abstract: The oxygen generation compositions include about 0.5-15% by weight of a substantially carbon-free metal fuel, and about 0.1-20% by weight of alkali metal silicate, stannate, titanate or zirconate as a reaction rate and core rheology modifier and chlorine suppresser. The oxygen generating compositions also contain about 0.1-15% by weight of a transition metal oxide catalyst; and the remainder is substantially an alkali metal chlorate or perchlorate.Type: GrantFiled: January 30, 1998Date of Patent: April 25, 2000Assignee: BE Intellectual PropertyInventors: Yunchang Zhang, James C. Cannon

Patent number: 6036925Abstract: This invention provides an air freshener candle product which is a slender combustible body composed of ingredients which include (1) candle-wax, (2) thermoplastic polymer and (3) particulate air freshener-release filler. The air freshener is released into the atmosphere under candle burning conditions. An invention taper-shaped candle can be produced by a continuous molding process.Type: GrantFiled: December 17, 1997Date of Patent: March 14, 2000Assignee: S. C. Johnson & Son, Inc.Inventors: Mary Beth Adams, Judith R. Zaunbrecher, Luz P. Requejo

Patent number: 6030583Abstract: The oxygen generating compositions contain carbon-free metal powder as fuel to minimize generation of carbon monoxide. The carbon-free metal powder can be selected from copper, zinc, and antimony, and mixtures thereof, and can be used in combination with tin or iron. The oxygen generating compositions produce a breathable gas upon ignition of the composition, and comprise about 1-15% by dry weight of the metal powder as a fuel; about 0.1-5% by dry weight of at least one alkaline compound; a transition metal oxide catalyst; and the remainder substantially comprising an oxygen source. The oxygen generating compositions can optionally include a binder. An oxygen generating candle can also have an ignition pellet having a composition of about 25-50% by weight copper, zinc or antimony, 5-20% by weight Co.sub.3 O.sub.4, about 2-5% by weight glass powder, 0-25% by weight KClO.sub.4, and the balance being substantially NaClO.sub.3.Type: GrantFiled: February 2, 1998Date of Patent: February 29, 2000Assignee: BE Intellectual PropertyInventors: Girish S. Kshirsagar, James C. Cannon, Yunchang Zhang

Patent number: 6013231Abstract: This invention provides a wick composition which is comprised of a polymeric strand such as polyethylene, which has a content of particulate cellulosic filler ingredient. The cellulosic ingredient contains chemically-bound air-freshener constituent. The wick is adapted for incorporation in a candle body. When the wick is ignited, it combusts with a controlled release of the air freshener constituent into the atmosphere.Type: GrantFiled: December 17, 1997Date of Patent: January 11, 2000Assignee: S. C. Johnson & Son, Inc.Inventors: Judith R. Zaunbrecher, Mary Beth Adams, Luz P. Requejo

Patent number: 6007736Abstract: The oxygen generation composition utilizes a catalyst selected from the group consisting of copper oxide, nickel oxide, and mixtures thereof, to catalyze the reaction or a chlorate or perchlorate based oxygen generating composition, smooth oxygen generation, improve the rheology of an operating chemical oxygen candle, and to facilitate the mixing of the candle ingredients. The oxygen generation composition typically comprises about a metal powder as a fuel; a catalyst selected from the group consisting of copper oxide, nickel oxide, and mixtures thereof; an additive as a chlorine remover and reaction rate modifier; and an oxygen source selected from the group consisting of alkali metal chlorates, alkali metal perchlorates, and mixtures thereof. The oxygen generating composition can optionally further include a binder.Type: GrantFiled: May 15, 1996Date of Patent: December 28, 1999Assignee: BE Intellectual PropertyInventors: Yunchang Zhang, James C. Cannon, Girish S. Kshirsagar
