Title: Shoe assembly with catcher for coring
Inventor: RADFORD STEVEN R
IPC: E21B25/14
Filed: 1992-04-03
Abstract: ABSTRACT      The application is directed to a shoe assembly with a core catcher for retaining a core of an unconsolidated rock or earth formation in a coring barrel. The shoe assembly includes a tube section adapted to fit removably within the core barrel near the coring bit. Two sets of hinged fingers are attached to the inner surface of the tube section on respective circumferential lines which are displaced from each other. The fingers are movable about the hinged ends between an open position in which the fingers do not significantly occlude the passageway, and a closed position in which the fingers do occlude the passageway. The fingers are biased toward the closed position by means of respective springs associated with each finger. When in the closed position, the two sets of fingers together occlude at least 90% of the cross-section of the passageway. The fingers are urged to the open position by the action of a core moving through the coring barrel away from the drilling end. When the motion of the core into the barrel stops and then reverses as the core barrel is withdrawn from the wellbore, the springs exert sufficient force to move the fingers into the core taken from an unconsolidated formation. Continued upward movement of the core barrel drives the fingers through the core material to the closed position. In the closed position, the core catcher holds the core in place in the core barrel during its removal from the drill hole.

Abstract: ABRÉGÉ TANDEM KANGOUROU La présente invention propose une nacelle amovible disposée sur une bicyclette à l'avant du conducteur de façon à pouvoir y transporter un enfant de la naissance à 4 ans avec plus de sécurité, confort et plaisir d'utilisation que tout autre modèle existant. La nacelle comprend une coque conçue pour être montée au moins temporairement sur une poutre centrale et sensiblement horizontale qui se prolonge entre le siège et le guidon de la bicyclette. La coque, creuse, est ouverte à sa partie supérieure arrière afin de recevoir un enfant en position assise et dont les jambes se prolongent de façon allongée vers l'avant de la nacelle, la tête de l'enfant faisant saillie au-dessus de la coque par l'ouverture arrière. Les parois supérieure et inférieure de la coque ménagent des ouvertures verticalement alignées que traverse le poteau du guidon de la bicyclette, les jambes de l'enfant se prolongeant de part et d'autre de ce poteau. La présente invention propose également un cadre modifié de bicyclette, dans lequel une colonne centrale comprend à son extrémité supérieure une extension horizontale dirigée vers l'arrière, c'est-à-dire au-dessus de la roue arrière, afin de libérer plus d'espace entre le siège et le poteau des guidons de la bicyclette pour l'installation de la nacelle. On suggère également que les guidons soient plus élevés que la normale afin de permettre au conducteur d'adopter une position plus verticale et ainsi éviter tout encombrement avec la nacelle et l'enfant.

IPC: F16J15/24
Filed: 1991-06-14
Abstract: A method and apparatus are provided for injecting sealant into a packing assembly chamber surrounding a valve stem 11 of a valve 2 without venting the pressure within the valve 2. A cylindrical body 60 is frictionally welded to the exterior of the valve 2 adjacent the packing assembly chamber. A drill bit is passed into the body 60 and through a set of packing seals 87. An opening is completed into the packing chamber. As the drill bit is withdrawn from the body 60, a second valve 70 is manually "closed" to isolate the packing chamber from the drill bit and prevent. the escape of pressurized fluid when the drill bit is removed from the seals 87. Thereafter, a device for injecting sealant is attached to the body 60 and the valve 70 is "opened" to allow the sealant to flow into the packing chamber.

Title: Functionally active selectin-derived peptides and ligand for gmp-140
Inventor: MCEVER RODGER P
IPC: A61K47/48
Filed: 1991-07-17
Abstract: Peptides derived from three regions of the lectin binding region of GMP-140 have been found to selectively interact with "selectins", including GMP-140, ELAM-1, and lymphocyte homing receptor. The three regions include amino acids 19-34, 54-72, and 66-89, based on the numbers of the residues contained in the peptide, with residue 1 de-fined as the N terminus of the mature protein after cleavage of the sig-nal peptide. Fucosylated sialyated lactosamine structures that bind to GMP-140 have also been discovered. The structure is created by ex-pression of .alpha.(1,3) fucosyltransferases capable of modifying acceptors containing .alpha.(2,3) sialic acid-substituted lactosaminoglycans. Le x, Ga1.beta.1,4(Fuc.alpha.1,3)GIcNAc.beta.1-R (where R is a protein or other carbohy-drate structure) forms the core of this sialyated structure. The peptides and carbohydrate structures are useful as diagnostics and for clinical applications in the modulation or inhibition of coagulation processes or inflammatory processes.

Inventor: DEANER MICHAEL J
IPC: C08J5/06
Filed: 1993-07-12
Abstract: Abstract The invention relates to a composition comprising a polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members.   The polymer and wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process.  The linear extrudate or pellet can have a cross-section of any arbitrary shape, or can be a regular geometric.   The pellet can have a cross-section shape having a volume of at least about 12 mm3.  Preferably the pellet is a right cylindrical pellet having a minimum radius of about 1.5 mm and a minimum length of 1 mm weighing at least 14 mg.  The invention also relates to an environmentally sensitive recycle of waste streams.   The polymer and wood fiber composite contains an intentional recycle of  a waste stream comprising polymer flakes or particles or wood fiber.   The waste stream can comprises, in addition to polymer  such  as  polyvinyl  chloride  or  wood  fiber, adhesive, paint, preservative, or other chemical stream common in the wood-window or door manufacturing process, or mixtures thereof.   The initial mixing step before extrusion of the composite material insures substantial mixing and melt contact between molten polymer and wood fiber.    The  extruded  pellet  comprises  a  consistent proportion of polymer, wood fiber and water.  During the extrusion,  water is removed intentionally to dry the material to a maximum water content of less than about 10 wt-% based on the pellet weight.   To make a structural unit,  the  pellet  is  introduced  into  an  extruder  or injection molding apparatus wherein, under conditions of temperature and pressure, the composite pellet material is shaped into a useful cross-section.  Alternatively, the extruded thermoplastic mass, in the form of a elongated linear  extrudate without  a  pelletizing  step,  can  be immediately directed after formation into an extruder or injection molding apparatus.
