Abstract: A staple drive assembly includes an actuation sled and at least one staple pusher. The staple drive assembly is adapted to fit within a staple cartridge having a plurality of staples and a corresponding number of retention slots. The at least one staple pusher includes at least one pusher plate for releasably engaging a backspan of a staple. The staple pusher may include a plurality of pusher plates that may be laterally and longitudinally spaced apart. An actuation member has at least one angled camming surface for engaging a complimentary angled surface of the at least one staple pusher. Camming engagement between the actuation member and the at least one staple pusher causes vertical movement of the at least one staple pusher. Lateral and longitudinal offset of the actuation member camming surfaces and the corresponding staple pusher following surfaces improves stability and control of the staple pusher during firing.

Title: Methods and apparatus for measuring flow velocity in a wellbore using nmr and applications using same
Inventor: SPEIER PETER
IPC: E21B47/10
Filed: 2002-09-09
Granted: 2012-08-07
Abstract: The present invention provides methods and apparatus for determining flow velocity within a formation utilizing nuclear magnetic resonance (NMR) techniques in which the shape of the resonance region is restricted so that sensitivity to radial flow or vertical flow is obtained (or both when more than one NMR tool is used). Flow velocity using these NMR tools is determined using decay amplitude, frequency displacement or stimulated echoes (where the spins are stored along the magnetic field instead of the transverse plane to exploit echo decays and frequency displacements) based on the application of adiabatic pulses. Based on the described NMR measurement of flow velocity, additional wellbore parameters may be obtained such as a direct measurement of permeability, an assessment of drilling damage to the wellbore, formation pressure, invasion rate of the mud filtrate or the migration of fine mud particles during sampling operations.

Abstract: Méthode et système nouveaux permettant de jalonner des éléments, dans un dispositif mécanique, afin dobtenir par conséquent un dispositif jalonné comportant au moins un dégagement souhaité entre les éléments indépendants des variations de matières premières, pour ce qui est des matériaux utilisés pour former les éléments. Des variantes sont fabriquées pour au moins une des paires de matrices de jalonnement utilisée par la presse de jalonnement, et la variante présentant un dégagement de jalonnement approprié est choisie chaque fois quun lot déléments change. Ainsi, les variations entre les lots de matières premières utilisés pour former les éléments, dune part, ne feront pas en sorte que les dispositifs jalonnés présenteront un desserrement latéral ou, dautre part, ne donneront pas des jalonnements ne respectant pas les spécifications du dispositif. Selon un deuxième mode de réalisation, des dispositifs sont dabord jalonnés par une presse de jalonnement conventionnelle et sont ensuite chargés sur une presse de fixation de dégagement qui déforme au moins une partie du dispositif jalonné afin dobtenir le dégagement souhaité. En limitant soigneusement la force avec laquelle la déformation est effectuée, le dégagement souhaité peut être obtenu sans quil ne soit nécessaire de traiter les éléments par lot lors du processus de fabrication.

Abstract: An electric cord retention device includes a base, at least one cord hold-down member, and at least one lid, which together receive and retain an electric cord. The base has a top forming a cord accommodation slot and a coupling portion. Two conductor pieces are received and fixed in the cord accommodation slot and has sharp tips located in the cord accommodation slot. The coupling portion is arranged adjacent to the cord accommodation slot. The cord is positioned in the cord accommodation slot and is depressed down by the cord hold-down member that is fit into the cord accommodation slot and positioned above the cord. The lid is tightened to the coupling portion by means of threading engagement, whereby rotation of the lid with respect to the coupling portion causes the cord hold-down member to move downward and apply a force to the cord against the sharp tips, making the sharp tips piercing into the cord to establish electric connection therebetween.

Abstract: Orally administrable, site-specific (colonic), particulate delivery systems including adsorbents are disclosed. When delivered specifically to the colon, they can remove various substances present in, or as they reach, the colon. Methods of treatment using the delivery systems, and methods of preparing the delivery systems, are also disclosed. The particulate delivery systems are based on adsorbent matrices encapsulated into and/or onto particles, which selectively deliver the adsorbents to the colon. Representative drug delivery devices include pectin beads, which can optionally be crosslinked with metal ions such as zinc and/or calcium. The delivery system protects the adsorbent and prevents its adsorbing effect in the upper gastro-intestinal (GI) tract. When the particles are made from pectin, and the beads are administered to the colon, specific pectinolytic enzymes in the colon degrade the pectin, allowing the adsorbent to be released and to be fully active. Antibiotics, toxins, and other absorbable substances present in the colon will then be inactivated by adsorption into or onto the adsorbent.
