Title: Communication cable termination
Inventor: VINING LOUIS DEVON
IPC: H01R4/24
Filed: 1999-03-08
Granted: 2003-05-20
Abstract: A modular communication plug for terminating a cable having a plurality of conductors disposed therein. The communication plug comprises a substantially hollow housing forming a chamber and having a conductor alignment region disposed at one end and an opening to the chamber at the other end. A carrier for orienting the conductors for reception in the alignment region is carried in the chamber. The carrier is inserted under the cable jacket and receives and organizes the conductors in channels formed therein to maintain a consistent routing of the conductors as they exit the end of the cable jacket. Furthermore, the carrier maintains this organization while an anchor bar or similar strain relief mechanism is tightened over the jacket. For adjusting the crosstalk generated in the plug, a crosstalk fixing member is interposed between the orienting member and the alignment region. A plurality of conductive terminals are disposed proximal to the alignment region for establishing electrical contact with the conductors.

Abstract: A method and apparatus for flowing liquid metal through a casting nozzle (170) includes an elongated bore having at least one entry port, at least one upper exit port (182), and at least one lower exit port (176). A baffle (178) is positioned proximate to the upper exit port (182) to divide the flow of liquid metal through the bore into at least one outer stream and a central stream, the outer stream flowing through the upper exit port (182) and the central stream flowing past the baffle (178) and toward the lower exit port (176).  The baffle (178) is adapted to allocate the proportion of liquid metal divided between the outer stream and the central stream so that the effective discharge angle of the outer stream exiting through the upper exit port varies based on the flow throughput of liquid metal through the casting nozzle.

Abstract: La présente invention concerne un procédé destiné à créer in vitro une évolution de la fonction protéine à partir d'une banque moléculaire. L'invention concerne en particulier la variabilité et la modification de la fonction protéique par la distribution aléatoire des segments de séquence polynucléotide. On peut obtenir une protéine présentant les caractéristiques voulues en incorporant des régions peptidiques de variants (motifs de variants) dans des régions peptidiques délimitées (séquence support). On peut obtenir lesdits motifs de variants à partir d'un ADN parent ayant été soumis à une mutagenèse afin de créer une multiplicité de dérivés différemment mutés de cet ADN; on peut également obtenir ces dérivés à partir de séquences in vivo. On peut ensuite incorporer les motifs de variants dans une séquence support, la protéine codée ainsi obtenue étant passée au crible afin de déterminer les caractéristiques voulues. Idéalement, ce procédé est utilisé pour obtenir des anticorps présentant les caractéristiques voulues, grâce à l'isolement de séquences individuelles d'ADN CDR et à l'incorporation de ces séquences dans un support provenant, par exemple, d'un anticorps totalement différent.

Abstract: In accordance with the present invention, the heater provides a core plug having one open axial end and one closed axial end to define a hollow housing. During installation, the closed end of the housing is secured into an engine core bore, such that at least a portion of housing projects inwardly of the bore and is immersed in engine fluid. Independently, a heating element, adaptable to an external power supply, is releasably inserted inside the hollow housing. Heat is therefore conducted directly through the housing directly to the engine fluid and the engine itself. A quick-release retaining member is installed to retain the heating element within the housing while still allowing free rotation of the heating element therein. The free rotation of the heating element allows an electrical connector from an external power source to interconnect with the heating element completely independent of the final orientation of the heating element inside the core plug or the end orientation of the core plug within the engine bore. The present invention therefore functions as both an immersion and a dry heater while simplifying installation and replacement.

Abstract: A can end is formed from sheet material in a single acting press (100) by blanking a workpiece (W) and holding the workpiece between a blanking punch (120) and a draw pad (128). The periphery of the workpiece is worked between a knockout (116) and a crown ring (130) to contour a crown (C). A bead punch (112) advances into the workpiece to form a shell (S) extending from the crown. The bead punch bottoms out on a bead die (134) and collapses to a predetermined position to form a plurality of beads (B) adjacent the shell by flowing a portion of the shell to form the beads while shortening the shell to less than specifications for the can end. The bead punch returns to an uncollapsed position during upstroke of the press to extend the shell to be within specifications.      Apparatus for forming a can end in a press (100) includes a fluidly supported die crown ring (130) having an upper surface defining a can end crown (C) contour. Knockout (116) is aligned with the die crown ring for engaging a workpiece (W) upon downstroke of the press to form a crown in the periphery of the workpiece. A punch (112), mounted to collapse against fluid pressure, forms a shell (S) extending from the crown and presses the workpiece against a bead die (134) to form a plurality of beads (B) adjacent the shell.  The punch collapses so that a portion of the shell flows to form the beads and returns to an uncollapsed position during upstroke to extend the shell to meet specifications.

Granted: 2009-04-14
Abstract: A stent (10) formed from cannula and having flexible segments (11) and high hoop strength segments (12) alternating therealong.  Axial tie bars (21, 22) interconnect the segments; minimal length reduction would occur upon expansion. In the high hoop strength segment (12), struts (16) are initially parallel in the unexpanded strut condition, while in the flexible segment (11), struts (14) extend from a respective bight (15) to converge at distal ends when unexpanded. In one embodiment, certain adjacent struts (16) of the hoop segment are spaced apart by a large gap (20) while others are spaced apart by a small gap (18).  In another embodiment all the struts (16) of the hoop segment are spaced apart uniformly from each other (or from an axial tie bar) by a small gap (23), resulting in minimizing the occurrence of fatigue of high-stress sites upon expansion/contraction cycles from continuous pulsatile events.

Abstract: A method of solid state welding for joining metal parts having opposed planar and parallel surfaces which includes quickly heating the opposed surfaces of the metal parts with a high frequency induction heater to the hot working temperature of the metal parts in a non-oxidizing atmosphere, continuously moving at least one of the parts relative to the other part generally parallel to the parallel surfaces of the parts, and quickly bringing the opposed surfaces of the parts together with an axial force approximately equal to the conventional friction welding forging force while continuing the relative motion of the parts until the absorbed kinetic energy is approximately equal to ten percent of the energy input required by conventional friction welding. The resultant weld is of a quality equal to or greater than normal friction welding but has a much smaller volume of flash and requires significantly less kinetic energy than conventional friction welding and is performed at rotational velocities well below the normal critical surface velocity of friction welding. The welded metal part includes a generally planar flash extending radially from the inner section of the opposed planar welded surfaces having a volume corresponding to a combined loss of length of less than 0.2 axial inches per inch of wall thickness. Thus, the disclosed solid state welding method is substantially more efficient than prior fricti on or other welding methods and results in an improved product.
