Abstract: A telecommunications connector includes first and second pairs of electrical conductors. The first and second pairs of conductors are arranged in one region of the connector such that one conductor of the first pair is selectively positioned to be closer to both of the conductors of the second pair than is the other conductor of the first pair, and such that the one conductor of the first pair couples a common mode signal of a first polarity onto the conductors of the second pair. In another region of the connector the other conductor of the first pair is selectively positioned to be closer to both of the conductors of the second pair to asymmetrically couple a common mode signal of a second polarity onto the conductors of the second pair.

Abstract: The present invention is a safety syringe for use with a plurality of interchangeable needles. The plurality of needles may be inserted by the user into the safety syringe for use. In operations, the user selects the desired needle, e.g., a needle having a particular gauge or size or of a particular type. The user inserts the needle (14) into a safety syringe (10) comprising a barrel (6), a needle assembly area (18) located within or attached to the barrel and a plunger (66). The needle couples to the syringe by a number of means. For instance, a locking mechanism (20, 22) may be used by which a needle hub located within the needle assembly has an area adapted to mate with a corresponding area on the needle. Or, the needle may be formed as part of a separate needle assembly, whereby the user will place the entire needle assembly onto the end of the syringe barrel.

Abstract: A metal roof truss assembly is provided comprising a plurality of elongated structural members, including a top chord, a bottom chord, and a web member. Each structural member comprises a planar base and planar legs extending from the longitudinal edges of the base. The base and the legs define an open longitudinal channel. A flange integral with the longitudinal edges of each leg has a planar first portion extending outwardly from the legs and a planar second portion extending from the longitudinal edges of the first portion of the flanges. The end of a first structural member is inserted into the channel defined by the legs and the base of a second structural member. The inserted end of the first structural member has no flanges for a length equal to at least the depth to which the first structural member is received in the channel of the second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.

Abstract: A syringe apparatus and process for using the same is provided, the syringe apparatus having a barrel, a plunger movable within the barrel, a needle assembly attached to an end of the barrel and having a passageway therethrough, a deformable base positioned within the barrel, flexible supports included on the deformable base, a spring within the passageway of the needle assembly, a hollow needle passing through the passageway, an enlarged head on the needle, and a rupturable web on an end of the plunger, whereby when the plunger moves through the barrel toward the needle assembly, a fluid can be moved from the barrel through the hollow of the needle, and continued movement of the plunger flexes the supports and moves the deformable base downwardly until such time a sufficient force is imparted to the rupturable web by the enlarged head to tear the web, the deformable base then releasing the needle due to force applied by the spring to project the needle into the interior of the plunger.

Abstract: A thermoplastic polyolefin composition suitable for slush molding comprising a blend of polypropylene, styrenic elastomer, linear low density polyethylene and a hydrocarbon-based process oil. Optional components include an ethylene copolymer elastomer, polymer additives such as polymer surface modifiers, powder flow additives, stabilizers and/or color pigments. The compositions exhibit a low melt viscosity during processing and improved surface quality for the molded article. An exemplary composition includes about 20-50 wt. % polypropylene or copolymer thereof, about 20-60 wt. % of a styrenic elastomer, about 5-50 wt. % linear low density polyethylene, and about 2-25 wt. % of a hydrocarbon-based process oil. The zero shear viscosity of the composition suitable for slush molding is in the range of about 300-900 Pa·s over a processing temperature range of 180-260° C.

Abstract: Systems, including methods, apparatus, and kits, for fixing bones, such as rib bones, with bone plates.

Abstract: An adhesive composition is provided which is suitable for the bonding of polymeric materials, in whole or in part, such as composite resins, or methacrylate-containing glass-ionomer filling materials, to tooth enamel, or tooth dentin, or to other hand tissues of the human body, such as bone. The composition comprises an unsaturated carboxylic acid ester, an unsaturated phosphate ester and other crosslinking agents. The especially preferred phosphates (which are provided as new compounds) are those of formula (I) in which: R1 is a hydrogen atom, alkyl C1-C4, or CN; R is an aliphatic, cycloaliphatic or aryl radical containing from 1 to 10 carbon atoms and having a valence of n+1; n is an integer from 1 to 5, preferably from 3 to 5.

The via transitions provide ground-signal-ground interconnection between coplanar waveguides disposed on opposite sides of substrate. Adjacent via transitions are anisotropically etched from opposite surfaces of the substrate to form the via transitions. The ground-signal-ground configuration provides RF impedance matching at the via transition.
