Title: Multiple cutter rotary hammer bit
Inventor: NIEVES MARCELO REYES
IPC: E21B10/44
Filed: 2000-10-31
Abstract: A drill bit (10) for use in rotary hammer drilling machines to drill holes in rock, masonry and concrete which includes an axially extending shank (12) having a plurality of helical discharge grooves (16, 18) therein and defining a convex end face (14). A cylindrical projection (20) is centrally disposed on the end face of the shank (12) and defines a pyramid-shaped cutting tip (24). A plurality of primary cutting members (30), generally rectangular in configuration, are embedded in the shank (12) such that the cutting members (30) are spaced from and extend radially from the cylindrical projection (20) so as to define gaps between the cutting members (30) and the projection (20). One of the cutting members is laterally adjacent an upper end portion of each of the discharge grooves (16, 18). The combination of the cylindrical projection (20) and surrounding primary cutting members (30) pulverize and pressurize drilled material and direct drilled material along the side wall of the cylindrical projection (20) and into the gaps between the projection and the primary cutting members where the material is compressed to assist in the drilling process and enhance drilling speed and is subsequently directed into the discharge grooves (16, 18) for removal.

Title: Color customization for paint application assembly
Inventor: DION MARK E
IPC: B01F15/00
Filed: 2002-06-06
Abstract: A method of painting a product in a production painting facility includes the steps of selecting a hue and a chroma corresponding to the hue. The production painting facility utilizes a plurality of base paints that are mixable to constitute the hue and chroma selected. The base paints are pumped to a blending device in a ratio determined to be necessary to formulate the hue and chroma selected. The base paints are blended in the blending device according to the predetermined ratio forming a secondary paint having the hue and chroma previously selected. The secondary paint is delivered to a paint applicator such as an atomizer bell or an equivalent and is applied to the product being painted. The base paints are mixed at the production facility to create a virtually limitless number of secondary paint colors with only a limited number of base paints.

Abstract: The present invention is directed to a capture assay to simultaneously screen for HBV, HCV and HIV nucleic acids in samples such as plasma. The nucleic acids including both viral DNA and RNA are purified from the plasma samples in a single extraction procedure. In one embodiment, a mixture of degenerate biotin-labelled PCR primers specific for the HBV, HCV, HIV-1 type M and HIV-1 type O are used to amplify any of these viruses which may be present in plasma. Amplified products are captured by hybridization to immobilized capture sequence, and thereafter detected. An internal control vector containing a synthetic fragment flanked by sequences corresponding to the HBV  primers was designed to monitor sample recovery during extraction, amplification and detection. All major subtypes of HBV, HCV and HIV-1 including HIV-1 type O have been confirmed and detected by the assay.

IPC: A61F2/36
Filed: 2002-08-22
Abstract: Précis Un cotyle expansible et rétractable est conçu pour éliminer les difficultés du positionnement dans l'acétébulum du patient. Ce dispositif comprend un cotyl e hémisphérique partiellement fendu à six endroits, pour faciliter l'expansion par un noyau à emmanchement conique. Le cotyle expansible est conçu pour entrer librement, ou avec une légère pression, dans la cavité osseuse qui a été fraisée au préalable. Le noyau conique est conçu pour être fixé à un impacteur-orienteu r gradué, en degrés, pour maximiser le positionnement souhaité. La force requise pour le positionnement est appliquée graduellement. L'inclinaison et l'antéversion pourront être vérifiées, en tout temps, lors de l'implantation. Le mécanisme retentif de l'impacteur-orienteur permettra de retirer le noyau conique, à volonté, pour repositionner le cotyle, si nécessaire. Le positionnement final sera sécuris é, avec des vis, pour empêcher le noyau de se déplacer. Le remplacement éventuel du coty le sera grandement facilité en retirant les vis et le noyau conique de sa position d e contrainte; le cotyle osseux pourrait alors recevoir un autre implant, suite au fraisage minimum requis.

Abstract: L'invention concerne un train planétaire capable de fonctionner comme engrenage réducteur lorsque le planétaire (5) est bloqué par une roue libre (8), et en entraînement direct lorsque l'embrayage (10) est engagé. La structure de couplage et de commande globale concernant le changement de rapport est essentiellement groupé sur l'élément planétaire (5) qui peut coulisser par rapport à un dispositif convertisseur (111) et forme une seule pièce avec ce dernier, dispositif qui engage le frein (9) lorsqu'il se désengage de l'embrayage (10), et inversement. Le frein (9) est monté mécaniquement en parallèle avec une roue libre (8), et permet une opération de réduction de vitesse lorsque le couple appliqué à l'arbre d'entrée (31) est un couple de retardement. La roue libre est montée en parallèle avec un palier axialement non coulissant (54) entre un arbre de stator (21) et un support (51) couplé pour une rotation commune avec un élément planétaire (5) et un coulissement mutuel avec ce dernier. L'actionnement de l'élément de commande (111) est réalisé par une commande hydraulique (116), des ressorts (114) et l'engagement de la poussée axiale de la denture hélicoïdale (F1, F2). L'invention est utile pour simplifier la commande, garder la possibilité d'autres couplages sélectifs, permettre d'autres conditions d'exploitation avec les autres éléments rotatifs (6, 7) du train, et pour éviter les paliers de butée.

Abstract: The invention relates to an osteosynthesis implant (1) that preferably consists of a bioresorbable plastic material. The inventive implant receives the longitudinal fixation elements (10) to be anchored in the bone, especially in the form of wires, nails, pins or screws. The openings destined to receive the fixation elements (10) do not completely extend through the implant (1) like in conventional bone plates or intramedullary nails but are degenerated to indents (2) in the surface of the implant (1) so that they may serve as a guide for the fixation elements (10) to be guided through the implant (1). The inventive implant (1) allows insertion of the fixation elements (10) in the bone t diverging angles and crossing one another, so that the fixation elements (10) extending intramedullarly or in the spongiosa are primarily prevented from migrating in a proximal or distal direction.

Abstract: A small percentage of cells within an established solid tumor have the properties of stem cells. These solid tumor stem cells give rise both to more tumor stem cells and to the majority of cells in the tumor that have lost the capacity for extensive proliferation and the ability to give rise to new tumors. Thus, solid tumor heterogeneity reflects the presence of tumor cell progeny arising from a solid tumor stem cell. We have developed a xenograft model in which we have been able to establish tumors from primary tumors via injection of tumors in the mammary gland of severely immunodeficient mice.  These xenograft assay have allowed us to do biological and molecular assays to characterize clonogenic solid tumor stem cells. We have also developed evidence that strongly implicates the Notch pathway, especially Notch 4, as playing a central pathway in carcinogenesis.
