Abstract: La fabrication des drains antibactériens sans soudures de qualités demande un équipement sophistiqué et coûteux. Ce drain d'évacuation des fluides est sans soudure. Refermé, il est parfaitement hermétique ne laissant qu'une mince fissure entre le corps du drain et son couvercle. Il comprend un corps cylindrique, une anneau d'ancrage, un couvercle équipé d'un joint de néoprène, pouvant être perforé au besoin et un panier à sédiment. Sa forme est produite dans une feuille d'acier inoxydable roulée sur une matrice. Les avantages antibactériens que possède l'acier inoxydable ne sont donc pas modifiés par les soudures. Cette conception unique donne au drain les avantages suivants : Peu coûteux, non corrosif, non poreux, exempt de joint, résistant à l'usure, aux acides, aux solvants, aux vapeurs d'eaux sous pressions. Il est donc parfaitement adapté aux industries qui oeuvres dans les secteurs de la santé et de l'alimentation où un environnement antibactérien est nécessaire.

Title: Improved trolley wheel
Inventor: VAN DYKE VERLAN
IPC: B65G39/02
Filed: 1998-12-17
Abstract: An improved trolley for use on a track. The improved trolley is of a sandwich construction having a wear resistant interior and a pair of metal end plates.  The wear resistant material is preferably plastic or other material designed to avoid damaging a track along which the trolley rides. The end plates are preferably stainless steel and of a diameter greater than the diameter of the center wheel to prevent the trolley from becoming dislodged from a track.

Filed: 1999-01-15
Abstract: A color-to-monochrome image conversion technique is disclosed. After the color image is converted to a monochrome input image and a plurality of primary-color input images, boundary information is extracted from the plurality of primary-color input images. The boundary information discriminates between different colors with the same lightness in the color image. Thereafter, the boundary information is superimposed as a binary image on the monochrome input image to produce the monochrome image. Therefore, a boundary between different colors with the same lightness can be easily imagined and be visibly displayed.
Patent CA-2259143-A1 (CA)
Inventor: BRASELMANN SYLVIA
IPC: A61K38/00
Filed: 1997-06-26
Abstract: The present invention relates to the discovery, identification and characterization of nucleotides that encode the G protein regulated phosphatidylinositol-3' kinase, a heterodimeric enzyme which produces the intracellular messenger phosphatidylinositol (3,4,5)-triphosphate in response to activation of trimeric G protein-linked receptors. This novel protein, comprised of a catalytic subunit, p120, and a regulatory subunit, p101, is found in cells of hematopoietic origin and is involved in immune system responses which cause inflammation. The presence of p101 subunit is largely responsible of the dramatic stimulation of kinase activity in the presence of activated trimeric G proteins. The invention encompasses <u>p101</u> and <u>p120</u> nucleotides, host cells expression systems, p101 and p120 proteins, fusion proteins, polypeptides and peptides, antibodies to these proteins, transgenic animals that express a <u>p101</u> or <u>p120</u>  transgene, or recombinant knock-out cells and animals that do not express the <u>p101</u> or <u>p120</u> gene, antagonists and agonists of the enzyme, and other compounds that modulate <u>p101</u> or <u>p120</u> gene expression or enzyme activity that can be used for diagnosis, drug screening, clinical trial monitoring, and/or treatment of inflammatory disorders.

Title: Pipe coupling
Inventor: BIRD EDWIN A
IPC: F16L21/04
Filed: 1999-06-08
Abstract: A pipe coupling (10) for coupling and sealing adjacent ends of two pipe sections (12, 14) of the same or different outer diameters. The pipe coupling (10) includes an annular sleeve (24), a pair of annular gaskets (22) and a pair of follower flanges (20) that surround the adjacent ends of the pipe sections (12, 14). The gaskets (22) have inclined front walls (42) that are angled generally complementary to clamping surfaces (28) formed at opposite ends of the sleeve (24). The gaskets further include inclined back walls (52). As the follower flanges (20) are urged toward the opposite ends of the sleeve (24), the inclined back walls (52) of the gaskets (22) cooperate with skirts (32) formed on the follower flanges (22) to cause the gaskets (22) to readily toe-in toward the outer walls of the pipe sections (12, 14) at relatively low torque and cause sealing engagement with pipe ends sections (12, 14). The follower flange skirts (32) may include inclined skirt walls (60) to further facilitate action of the gaskets (22).

Title: Portfolio structuring using low-discrepancy deterministic sequences
Inventor: PAPAGEORGIOU ANARGYROS
IPC: G06Q40/00
Filed: 1999-08-18
Abstract: In securities valuation, in setting the initial offering price of a financial instrument, or in later revaluation as financial parameters such as interest rates may change, an estimate of the value of the instrument may be represented as a multi-dimensional integral. For evaluation of the integral, numerical integration is preferred with the integrand being sampled at deterministic points having a low-discrepancy property. The technique produces approximate values at significant computational savings and with greater reliability as compared with the Monte Carlo technique. Further to estimating the value of a complex security, sampling at points of a low-discrepancy deterministic sequence can be used in estimating value at risk in portfolio structuring.
