Patent number: 8859222Abstract: Methods and compositions for detection of microbial contaminants in peritoneal dialysis solutions are provided. A novel cause of aseptic peritonitis is provided—aseptic peritonitis associated with gram positive microbial contamination of a dialysis solution. Peptidoglycan is a major component of a gram positive bacterial cell wall and thus can serve as a marker for gram positive bacteria. In this regard, testing for peptidoglycans can be utilized to effectively prevent peritonitis in patients that use the peritoneal dialysis solutions, such as peritoneal dialysis solutions that contain a glucose polymer including an icodextrin and the like.Type: GrantFiled: August 23, 2013Date of Patent: October 14, 2014Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Leo Martis, Mehul Patel, Joseph A. Giertych, James W. Mongoven, Jacqueline A. Kunzier, William F. Owen

Patent number: 5247950Abstract: Treating cigarette paper with (1) binary combinations of the sodium and potassium salts of a carboxylic acid or (2) binary combinations of an alkali metal chloride and an alkali metal carboxylate provides a means of controlling the static burning rate of cigarettes wrapped in these papers. Burn rate control is functionally implemented by varying (1) the sodium to potassium cation ratio at constant total alkali metal cation weight for the former binary combination and (2) the ratio of the alkali metal cation from the chloride to the alkali metal cation from the carboxylate at constant total alkali metal cation weight for the latter binary combination. This means of burn rate control is effective for cigarette papers containing various inorganic fillers and weighing less then 25 g/m.sup.2 to over 45 g/m.sup.2.Type: GrantFiled: July 2, 1991Date of Patent: September 28, 1993Assignee: P.

Patent number: 5107864Abstract: A wrapper for a smoking article which, when wrapped about a tobacco column, provides improved sidestream smoke reduction, improved ash formation, and improved mainstream smoke taste and sidestream smoke odor subjectives. These objectives are attained by forming a single cellulosic sheet containing a filler combination of magnesium hydroxide activated carbon, and calcium carbonate. In addition, the sheet may be treated with a burning chemical such as potassium citrate, an organic acid such as citric acid, and a sugar such as sucrose. Considerable latitude exists in regard to sheet basis weight, filler levels, sheet porosity, burn rate and size press solution treatment in order to optimize product requirements.Type: GrantFiled: February 19, 1991Date of Patent: April 28, 1992Assignee: P.

Patent number: 5065777Abstract: A cigarette paper is disclosed which, when fabricated into a cigarette with a suitable tobacco column, statically burns at an acceptable rate, produces a light-colored, well-formed ash which clings tightly without premature flaking, and delivers both mainstream and sidestream smoke with a subjectively pleasant taste and aroma.Type: GrantFiled: April 26, 1990Date of Patent: November 19, 1991Assignee: P. H. Glatfelter CompanyInventor: William F. Owens, Jr.

Patent number: 4450847Abstract: A wrapper for smoking articles such as cigarettes, cigars and the like containing precipitated amorphous magnesium hydroxide gel. Other components of the filler for the wrapper can be either an unreactive grade of magnesium oxide or calcium carbonate. For the most effective reduction in sidestream tar and visible sidestream smoke the basis weight of the paper should be between 30 g/M.sup.2 and 100 g/M.sup.2. The filler should constitute 30% to 60% of the total sheet weight. The precipitated magnesium hydroxide gel should be present to the extent of approximately 5% to 50% by weight of the total filler and preferably between 10% and 25%.Type: GrantFiled: April 7, 1982Date of Patent: May 29, 1984Assignee: Olin CorporationInventor: William F. Owens

Patent number: 4433697Abstract: A wrapper is provided for smoking articles such as cigarettes, cigars and the like having incorporated therein at least 1% by weight of certain ceramic fibers in the paper furnish in combination magnesium oxide and/or magnesium hydroxide fillers, whereby the combination acts to significantly reduce visible sidestream smoke emanating from the smoking article during static burning, and improves ashing. Wrappers made according to this invention may be made by incorporating the magnesium hydroxide, magnesium oxide and the other fillers in the wrapper pulp furnish containing the ceramic fibers or either or both of the fillers may be applied to the improved wrapper as a coating for the papers. In the case of cigarette papers, the ceramic fibers may be added to an ordinary paper furnish such as pulped wood or flax fibers. The furnish of fiber pulp and ceramic fibers and fillers are used to make a paper sheet on conventional papermaking machines.Type: GrantFiled: April 7, 1982Date of Patent: February 28, 1984Assignee: Olin CorporationInventors: Warren K. Cline, William F. Owens

Patent number: 4174719Abstract: An improved ventilated filter tip cigarette is provided utilizing a unique combination of porous filter plug wrap having a porosity of from about 300 to 4000 Filtrona air permeability units with a microperforated tipping envelope having perforations averaging less than about 0.01 mm.sup.2 each in open area. The relationship of plug wrap porosity combined with the size of microperforations in the tipping envelope provide cigarettes with maximum selective reductions in carbon monoxide yields and only minor reductions in nicotine yields as compared to constituent yields heretofore obtained in the smoke from ventilated cigarettes.Type: GrantFiled: June 29, 1977Date of Patent: November 20, 1979Assignee: Olin CorporationInventors: Richard H. Martin, William F. Owens, Jr.

Patent number: 4119105Abstract: An improved smoke control device for smoking articles which contains a valve operative to close off the flow of smoke drawn through the smoking article depending upon the pressure drop or draw rate of each individual puff. Preferably, the valve comprises a resilient flap member responsive to the puff pressure drop for restricting or closing off smoke drawn through the smoking article and which will reopen after the pressure is relieved, thereby limiting each puff to a predetermined yield consistent with that obtainable in a normal puff.Type: GrantFiled: January 31, 1977Date of Patent: October 10, 1978Assignee: Olin CorporationInventor: William F. Owens, Jr.
