Granted: 2007-01-16
Abstract: Controlled release non-aqueous air care gels comprising from about 1 to about 50 percent on a weight basis of diblock, triblock, multiblock and/or radial block copolymers based on synthetic thermoplastic rubbers. The ratio of the diblock to triblock, multiblock and/or radial block copolymers can be varied from about 0 percent to about 100 percent in either direction. The material to be gelled is hydrocarbon, one or more hydrocarbon-soluble substances, or mixtures thereof, which based on its physical properties plays an important role in setting the controlled release rate. The composition of the hydrocarbon can vary in carbon length from about C-5 to about C-30 and can vary in vapor pressure up to about 600 mm Hg at 20 ° C. The hydrocarbon range on a weight basis is from about 20 to about 95 percent of the total weight of the gelled composition. The controlled release agent or active agent is one or more air care active substances, such as fragrances, deodorizers, masking agents, pest repellents or pesticides, and may comprise from about 0.1 to about 30 weight percent of the gel.

Inventor: TARGAN STEPHAN R
IPC: C12Q1/68
Filed: 1997-04-11
Granted: 2009-07-07
Abstract: Provided herein is a method of diagnosing a clinical subtype of Crohn's disease (CD) by determining whether perinuclear anti-neutrophil antibody (pANCA) is present in a patient with CD, where the presence of pANCA  indicates a clinical subtype of CD with features of ulcerative colitis (UC). The present also provides a method of diagnosing clinical subtypes of Crohn's disease in a patient with CD by determing whether pANCA or speckling anti-pan polymorphonuclear antibody (SAPPA) is present in the patient with CD, where the presence of pANCA indicates a clinical subtype of CD with features of ulcerative colitis and where the presence of SAPPA indicates a clinical subtype of CD having perforating, fistulizing or small bowel obstructive disease. The invention further provides a method of diagnosing clinical subtypes of Crohn's disease in a patient with CD by determining the presence or absence of ANCA, pANCA and SAPPA in the patient with CD and determining the presence or absence of anti-Saccharomyces cerevisiae antibodies (ASCA) in the patient with CD, where the presnece of pANCA combined with the absence of ASCA  indicate a clinical subtype of CD with features of UC, the presence of SAPPA indicates a clinical subtype of CD having perforating or fistulizing disease or small bowel obstructive disease, and the presence of ASCA combined with the absence of ANCA indicates a clincial subtype of CD lacking features of ulcerative colitis and having perforating or fistulizing disease or small bowel obstructive disease. Kits for diagnosing clinical subtypes of Crohn's disease, which contain neutrophil and antigen specific for ASCA, also are provided.

Title: Method of producing saponified ethylene-vinyl acetate copolymer pellets
Inventor: KUNIEDA MAKOTO
IPC: B29B9/06
Filed: 1998-09-07
Granted: 2004-03-30
Abstract: A process for continuously preparing pellets of a saponified ethylene/vinyl acetate copolymer (EVOH), by continuously extruding an EVOH solution into a coagulating fluid in the form of a strand and cutting the strand, wherein the ratio of the weight X of the coagulating liquid, to the weight Y of the strand of EVOH, X/Y, is regulated to 50 to 10000. Preferably, the coagulating fluid contains 1 to 10000 ppm of carboxylic acids, 1 to 50000 ppm of carboxylic esters, or 1 to 15000 ppm of carboxylic acid salts. Further, preferably, the water content of the continuously prepared EVOH pellets is regulated to 20 to 80 % by weight, before the EVOH pellets are brought into contact with an aqueous solution (having a particular concentration) of at least one compound selected from the group consisting of boron compounds (B), acetic acid salts (C), and phosphorus compounds (D). Alternatively, the EVOH  pellets thus obtained are preferably dried by the combination of stationary drying with fluidized drying.
Patent CA-2273068-C (CA)

Granted: 2003-08-12
Abstract: A nut consists of integral metal material and has a female screw thread formed with a rolled tap in a screw hole that opens substantially perpendicularly to an end surface of one end of the nut. A lead thread is located at an opening end of the screw hole and has a shape including a concave curved portion and a linear tapered portion that are continuous with each other, and extend along the overall periphery of the opening end of the hole. Due to the special lead thread, the first thread formed by the rolled tap adjacent to the lead thread will not have a concave groove along its crest, although subsequent threads have such a concave groove along the thread crest as a characteristic of thread formation with the rolled tap. Such a thread structure avoids cross-threading when a bolt is engaged in the nut.

Abstract: Abrasive jet stream polishing, wherein an abrasive is suspended in a flowable jet medium (24) and projected at high velocity and pressure at a workpiece (12), where the jet is projected at the surface to be polished at an oblique angle. The method is substantially improved by forming the medium of a polymer having reformable sacrificial chemical bonds which are preferentially broken under high shear conditions. Projecting the medium and suspended abrasive breaks the reformable sacrificial chemical bonds while polishing. The chemical bonds will reform permitting recycling (80, 82, 84) of the medium and abrasive for reuse in the method.      The jet is effective at relatively low pressures of about 5 to about 80 MPa.

Abstract: The clip includes a body and a lid slidably mounted on tracks on the sides of the lid. A trough formed in the body receives a cylindrical item, such as a rod, pipe or conduit. The lid slides between an open or pre-driven position wherein the lid does not cover the trough, and a closed position wherein the lid covers the trough. The tracks are somewhat inclined with respect to the body so that the lid does not contact the rod in the trough until immediately prior to the closing of the lid. Sloped stop ramps on the body detent engage apertures in the lid in both the open position and the closed position. The underside of the body includes a second trough with a "rabbit ear" detent mechanism to engage a second cylindrical item, such as a rod, pipe or conduit.
