Title: Body piercing jewelry
Inventor: HANSON CARL RALPH
IPC: A44C17/02
Filed: 1998-07-16
Abstract: Jewelry for insertion through the bore of a body part piercing. The jewelry comprises a crescent-shaped body (50) of a memory resilient material having terminal ends (54, 56) adapted to be inserted within a piercing. A concave depression (58) is defined on an inner side of one of the terminal ends (54).  A second body such as a ball bearing (52) is insertable between the terminal ends (54, 56) and is firmly seated within the concave depression (58) to clasp the jewelry within the piercing. The ball bearing (52) has a diameter slightly greater than a distance between the terminal ends (54, 56) of the crescent shaped body (50) to first force the terminal ends (54, 56) apart and then create an inwardly directed biasing force against the ball bearing (52) when the ball bearing (52) is inserted therebetween, thus firmly holding the ball bearing (52) within the concave depression (58) and between the terminal ends (54, 56).

IPC: G01N21/89
Filed: 2000-02-15
Abstract: The invention relates to a device and a method for detecting, identifying and relocating defects in a material strip of great length. In order to enable defects to be relocated reliably and quickly with relatively little effort, the material strip is checked for defects, and position indicators are applied to the material strip continuously over its length. In the event of a defect being observed, an associated defect position indicator is stored, and during the subsequent relocation of a defect, a current starting position indicator is established, and the material strip is moved over a conveying length which is calculated from the established starting position indicator and the stored defect position indicator.

Abstract: La présente invention concerne la détection de produits de fragment d'échantillon de clivage de mésappariement de paires de bases, détection qui indique la présence et la séquence d'un ADN cible. La détection de la cible est améliorée par amplification par recyclage de cibles avec maintien d'une température de dosage comprise entre le point de fusion du duplex cible/ADN échantillon et celui du complexe cible/produit, en présence d'un amplificateur comprenant de l'acétate d'ammonium ou un dérivé d'amine (par exemple, de la diéthylamine, de la pipéridine, ou du carbonate d'ammonium). Le clivage réduit la taille du duplex et abaisse ainsi le point de fusion. L'amplificateur libère la cible du complexe, permettant ainsi une catalyse ultérieure de clivage et amplifiant efficacement le signal à détecter. La figure présente un schéma du mécanisme théorique de clivage de mésappariement et d'amplification à l'aide d'acétate d'ammonium ou d'un dérivé d'amine.

Filed: 2000-05-30
Abstract: An internal oil separator for compressors of refrigeration systems is disclosed. This oil separator supplies an effective quantity of lubrication oil to the drive parts of a compressor, and protects the compressor from being unexpectedly damaged or locked. The oil separator accomplishes the recent trend of compactness of compressors, and prevents a bypass flow of the compressed refrigerant into the compressor.      This oil separator collaterally reduces operational noises of the compressor. In this oil. separator, an oil-separating chamber 21, having a generally U-shaped passage, is defined in the rear section of a compressor housing by a cover 2. The oil-separating chamber 21 has a guide wall 22, thus forming a desired U-shaped passage therein. Refrigerant inlet and outlet ports 13, 14 are formed on the rear wall of the housing. An oil-collecting part 17 is formed on the bottom of the oil-separating chamber 21 and stores recovered oil therein. This oil-collecting part 17 communicates with an oil return line 16 through an oil return channel 31 of a gasket 3, and so the recovered oil returns to the driving part chamber 18 of the compressor. The above gasket 3 is interposed between the housing 1 and the cover 2, thus accomplishing a desired sealing effect. An oil-separating plate 4 and/or a screen member 5 formed by single loop structure is preferably set within the oil-separating chamber 21.

Title: N-hydroxy-2-(alkyl, aryl, or heteroaryl sulfanyl, sulfinyl or sulfonyl)-3-substituted-alkyl, aryl or heteroarylamides as matrix metalloproteinase inhibitors
Inventor: LEVIN JEREMY IAN
IPC: A61K31/445
Filed: 1998-08-26
Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-.alpha.  converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-.alpha. from membrane bound TNF-.alpha. precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-.alpha. converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection having formula (I), wherein R2 and R3 form a heterocyclic ring and A is S, S(O), or S(O)2 and R1 and R4 are defined herein.

Title: Enhancement of the pro-fertility action of a molecule involved in sperm-egg binding
Inventor: AMANN RUPERT P
IPC: C07K14/47
Filed: 1999-03-12
Abstract: A synthetic peptide with enhanced pro-fertility action was produced by inclusion of additional amino acids at the carboxyl end of a previously disclosed synthetic peptide. Improvement in bioactivity over the previously disclosed peptide was demonstrated. A direct comparison of an earlier known synthetic peptide and said extended peptide involved brief exposure of sperm in vitro to one or the other peptide at several concentrations. When sperm then were evaluated in vitro using an egg-membrane substrat e, an increased percentage of sperm bound for cells exposed to the new extended peptide.  Similarly, when fertility of sperm after artificial insemination was the criterion, a greater percentage of eggs was fertilized by sperm exposed to the new extended peptide. In one preferred embodiment, this enhanced pro-fertility action was achieved with a peptide having a 68 amino acid sequence (SEQ ID  NO:1): Cys- Gln-Ser- Leu-Gln-Glu-Tyr- Leu-Ala-Glu-Gln- Asn-Gln-Arg-Gln- Leu-Glu-Ser- Asn-Lys-Ile-Pro- Glu-Val-Asp-Leu- Ala-Agr-Val-Val-Ala-Pro-Phe-Met-Ser-Asn-Ile-Pro-Leu-Leu-Leu-Tyr-Pro-Gln-Asp-Arg-Pro-Arg-Ser-Gln-Pro-Gln-Pro-Lys-Ala-Asn-Glu-Asp-Val-Cys-Val-Asn-His-His-His-His-His-His.

Title: Method and apparatus for steering saw blades
Inventor: OGG KENNETH ALLAN
IPC: B27B7/04
Filed: 2001-01-18
Abstract: A method and apparatus for steering saw blades which includes an arbor rotatable about a rotation axis. Saw blades are mounted on the arbor in such a manner that the saw blades rotate with the arbor and are angularly adjustable in relation to the rotation axis of the arbor. A rigid guide assembly is provided having a plurality of guides each of which accommodate one the saw blades, such that movement of the guide assembly angularly adjusts the saw blades in unison. A leading edge of each of the saw blades is positioned along a common alignment plane. A support is provided for the guide assembly. The support has an underlying pivot axis spaced from, and substantially perpendicular to the rotational axis of the arbor. This pivot axis is on the alignment plane such that the leading edge of each of the saw blades remain positioned along the alignment plane as the guide assembly is pivoted to move the guide assembly to alter the angular positioning of the saw blades. The method and apparatus avoids having to accommodate lateral offset when the saw blades are in. an angular position.
