The invention relates to a thermoplastic composition for a monolayer tube (T1, T2), and particularly to an air-conditioning circuit for a motor vehicle comprising tubes transporting a refrigerating fluid.

The composition comprises in weight fractions: more than 20% and up to 40% of a PA 6.10 and/or a PA 6.12, from 45% to less than 60% of a polyphthalamide having a Tg higher than 120° C. and selected from PA 6.I/6.T, PA 9.T, PA 10.T, PA 10.T/X, and from 10% to 20% of a compatibilizing system comprising a reaction product between (a) a polymer of olefin comprising an unsaturated epoxide and (b) a polymer of olefin comprising an unsaturated carboxylic acid, with weight ratio (a):(b) greater than 1.

Screw capping devices are configured to remain tethered to a container after opening of the container. The screw capping devices include a cylindrical wall having a section having an end closed by a bottom and a section having an open end, the section being connected to the section by a circumferential junction having a non-breakable connection and a breakable connection, the section further having a breakable connection extending parallel to the circumferential junction, the breakable connection and the breakable connection being configured to be broken during a first unscrewing of the section. The breaking of the breakable connections creates two arms retaining the section to the container.

An apparatus and process for molding workpieces usable for consumer products. The workpieces may be injection molded with a cavity formed by a core pin and have an undercut, such as internal threads, in the cavity. The apparatus has a drive system with a stripper plate mounted for alternatingly forward and retracting axial movement. The stripper plate is axially driven and drives a stripper sleeve barrel cam and a core pin base barrel cam, each having respective cam followers. The respective motions of the cam followers are superimposed on a stripper sleeve insert, which drives a core pin sleeve. The core pin sleeve is subjected to responsive three dimensional motion, allowing an internally threaded workpiece to be unscrewed from the core pin sleeve. The system does not require separate drives for the core pin sleeve, a single stripper plate drive being sufficient and further allows each mold cavity/core pin combination in a mold half to be unique.

The present disclosure provides for a bone screw formed of continuous fibers, for example. The bone screw may include a first portion having a cylindrical shape and extending in a longitudinal direction from a first end to a second end, for example. In various embodiments, the first portion may include a thermoplastic material and/or be substantially formed of a thermoplastic material. In various embodiments, the bone screw may include a second portion coupled to the first portion and surrounding the first portion, at least partly, for example. In various embodiments, the second portion may include a plurality of layers, each layer comprising a continuous fiber material, for example. In various embodiments, the continuous fibers may be oriented longitudinally, diagonally, helically, radially, etc. In various embodiments, the second portion may define an exposed thread pattern and a leading tip.

An in-mold shutter (140) for embedding in an injection mold (100, 200, 300) is described herein. The in-mold shutter (140, 240, 340, 440, 540) includes a shutter actuator (148, 548) that is configured to selectively engage a first mold shoe (130) of the injection mold (100, 200, 300) with a platen of a mold clamping assembly (996) to hold the first mold shoe (130) in an extended position (E), along a mold-stroke axis (X), during a step of molding a first molded article (102A) in the injection mold (100, 200, 300). Also described herein is a molded article transfer device (150, 250) for use with the injection mold (100, 200, 300). The molded article transfer device (150, 250) includes a shuttle (154) that is slidably arranged, in use, within the injection mold (100, 200, 300). The shuttle (154) defines a first aperture (156A), at least in part, that alternately accommodates: (i) a first mold stack (106A, 206A, 306A) arranged therein; and (ii) a first molded article (102A) received therein with opening of the first mold stack (106A, 206A, 306A).
