Patent number: 6168607Abstract: The trocar assembly of the present invention includes a tubular body portion, a sleeve, a unidirectional sealing means included within the sleeve and a funnel portion mounted around the sleeve. A perforating tool is insertable through the funnel, through the unidirectional sealing means and thence through the tubular portion of the trocar assembly into the body of a patient. All portions of the trocar assembly of the present invention are formed from materials which may not be readily sterilized by immersion in a sterilizing bath or autoclaving. Thus, the single use trocar assembly of the present invention may be only used once and will be destroyed if an attempt is made to resterilize the entire trocar assembly or any portion thereof.Type: GrantFiled: March 8, 1999Date of Patent: January 2, 2001Inventors: Arnaud Wattiez, Francis d'Arpiany

Patent number: 6087833Abstract: An apparatus and method for passively determining the depth and thickness of a subterranean geologic formation bearing hydrocarbons, e.g., oil and/or gas, or commercially important ore deposits, e.g., precious metals. The apparatus has an antenna to pick up extremely low frequency signals naturally emanating from the Earth's surface. In a preferred embodiment, the received signal is amplified and filtered. The signal is then modulated onto a carrier wave. The modulated signal is then filtered to eliminate one of the sidebands, for example, the lower sideband. An oscillator generates a tuning frequency which is then beat against the filtered, modulated signal in order to tune to a particular frequency. The oscillator sweeps through the range of frequencies, e.g., in the upper sideband portion of the filtered, modulated signal.Type: GrantFiled: July 2, 1998Date of Patent: July 11, 2000Assignees: John R. Jackson, Andreas M. Arismendi, Jr.Inventor: John R. Jackson

Patent number: 6071972Abstract: A disinfecting and sterilizing concentrate containing an aromatic dialdehyde and a neutral pH buffering system is provided. Aromatic dialdehyde concentrations of greater than 5 w/w % are achieved while maintaining the stability of the buffering system. A method and a kit for preparing a disinfecting and sterilizing concentrate is also provided.Type: GrantFiled: May 26, 1999Date of Patent: June 6, 2000Assignee: Ethicon, Inc.Inventor: Philip A. Block

Patent number: 6056793Abstract: This invention is a composition of matter useful as a compression-ignition fuel. The composition has from about 30 to about 95 mass % of a light synthetic crude or syncrude, preferably from Fischer-Tropsch synthesis or related processes, and from about 5 to about 70 mass % of a blending stock that improves one or more desirable fuel property(s) including but not limited to pour point temperature, viscosity and emissions generated during combustion in a diesel engine. The blend stock preferably has an average molecular weight less than the average molecular weight of the light syncrude. Preferred blending stocks include hydrocarbons and oxygenates, such as alcohols, and ethers, having average molecular weights less than 200, preferably less than 160. The composition may optionally also contain pour point depressants, cetane improvers, carbon-containing compounds which react with water, and/or emulsifiers.Type: GrantFiled: October 26, 1998Date of Patent: May 2, 2000Assignee: University of Kansas Center for Research, Inc.Inventor: Galen J. Suppes

Patent number: 5980925Abstract: Emulsions containing a dermal anchoring/substantive agent, such as glycerin, in high concentration enhance the activity of active ingredients, such as anti-microbial agents like chlorhexidine gluconate. Kits, compositions and methods pertaining to the same are provided. The invention finds application in cleansers such as hand washes, wound cleansers, body washes, mouthwashes, surgical scrubs, etc., and lotions, creams, foams and ointments. Specifically, one embodiment of the emulsion contains greater than 30% of an anchoring/substantive agent such as glycerin and an effective amount of chlorhexidine gluconate. Additionally, the product produced by the process of combining on the skin high glycerin and an anti-microbial is described.Type: GrantFiled: December 30, 1997Date of Patent: November 9, 1999Assignee: Ethicon, Inc.Inventors: Hunuman B. Jampani, Jerry L. Newman

Patent number: 5969026Abstract: Wettable fibers or filaments are prepared from a composition having a polymer which has a wetting agent incorporated therein. The polymer is selected from the group consisting of olefin polymers, polyesters and polyamides. The wetting agent consists essentially of a glyceride selected from the group consisting of a mono-glyceride, a combination of mono-glycerides and a mixed glyceride having a mono glyceride content of at least 85 percent by weight. The fatty ester group or groups in the glyceride each have from about 12 to about 22 carbon atoms. The olefin polymer is preferably polypropylene, LLDPE, LDPE and HDPE, more preferably polypropylene. The polyamide is preferably a nylon 6 and nylon 6,6. The polyester is preferably a polyethylene terephthalate and a polybutylene terephthalate.Type: GrantFiled: June 26, 1997Date of Patent: October 19, 1999Assignee: Techmer PMInventors: Ebrahim Mor, Vasanthakumar Narayanan

Patent number: RE37285Abstract: The present invention comprises novel preparations of polyoxypropylene/polyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. Because the preparations of polyoxypropylene/polyoxyethylene copolymers which comprise the present invention are a less polydisperse population of molecules than the prior an polyoxypropylene/polyoxyethylene copolymers, the biological activity of the copolymers is better defined and more predictable.Type: GrantFiled: November 19, 1999Date of Patent: July 17, 2001Assignee: Cytrx CorporationInventors: R. Martin Emanuele, Robert L. Hunter, Paula H. Culbreth
