International Classification:

C08L 6702

US Classification:

525177, 525175, 525176, 525183, 525184, 525217, 525218, 525220, 525221, 525222, 525227, 525240, 525425

Abstract:

We have developed a process and product which provide thermoplastic articles featuring a permanent outer surface which has selectively varied chemical functionality while maintaining the inherent mechanical properties of the base fiber. The process comprises the steps of: (a) adding a substantially organic molten component with CSP value of at least 8 to a molten thermoplastic polymer and mixing to substantially uniformly disperse the molten component in the molten thermoplastic polymer and form a heterogeneous blend wherein (i) the melt viscosity of the molten component is substantially less than the melt viscosity of the molten thermoplastic polymer; and (ii) the amount of the molten component in the molten thermoplastic polymer is up to about ten percent by weight based on the heterogeneous blend; and (b) melt processing the heterogeneous blend wherein the molten component preferentially locates near the surface of the molten thermoplastic polymer and substantially no chemical reaction occurs between the molten component and the molten thermoplastic polymer.

International Classification:

F16B015/99

US Classification:

411487, 411 2, 411392, 411424, 411901

Abstract:

A fastener, such as a nail, screw, etc. , which possesses supplemental support and/or retention capability is provided. The fastener includes an elongated auxiliary member secured interiorly to, exteriorly to, or along the shaft of the fastener. The auxiliary member is secured to the shaft at two or more portions of the shaft. The auxiliary member provides the shaft with additional support strength and/or enables fastened materials to be retained upon breakage or shearing of the shaft as a result of, for example, heavy tensile or shearing loads. To facilitate breakage or shearing of the shaft, the shaft may be provided with a deformation, such as a notch or reduced circumference, at one or more desired locations such that the shaft breaks or shears at the deformation(s), thereby allowing the auxiliary member to function as the sole member which retains the fastened materials. The auxiliary member may be sufficiently flexible and pliable such that, upon breakage or shearing of the shaft, retention of the materials is maintained but in a less stressed form.

The present invention provides specific surface activating polyamide (Formula (I)) and polyolefin (Formula (II)) additives. These additives may be used in thermoplastic polymers and more preferably in polyester. The resulting thermoplastic blend may be used to make articles, preferably fiber, and more preferably industrial fiber.

International Classification:

A61N 1/375

Abstract:

A header lock assembly includes a header lock pin and mating lead lock collar that provide a releasable coupling for attaching one or more leads to a device. The header lock assembly is configured to engage the lead to assure closure while not applying undue pressure on the lead. One or more notches in the header lock pin allow the lead to pass the header lock pin unimpeded while the header lock assembly is in an unlocked configuration. Rotation of the header lock pin engages a circumferential groove in the lead lock collar to secure the lead to the header. A slot in the top of the header lock pin provides an interface surface with a lead locking tool for rotating the header lock pin. The slot orientation provides a visual indication of the header lock assembly being in a locked or unlocked configuration.

International Classification:

A61B 17/34
A61N 1/05

Abstract:

A trocar assembly comprises an elongate shaft, a piercing tip at a distal end of the shaft, a handle at a proximal end of the shaft, and a retaining member. When a passer tube is positioned over the shaft, the retaining member engages with an inner surface or an outer surface of the passer tube to retain a position of the passer tube over the shaft.
