The invention relates to a biohybrid for the use thereof in the regeneration of neural tracts, comprising an implantable tubular hybrid structure which is degradable and biocompatible and characterized in that it comprises three layers of different porosity: an inner layer a), an intermediate layer b) and an outer layer c), with uninterrupted connection among them, the three layers consisting of the same porous hydrogel based on cross-linked hyaluronic acid, a biohybrid comprising the hybrid tubular structure described, which can contain a fibrous material, preferably poly-L-lactic acid, to a method for producing said tubular hybrid structure and said biohybrid, and to the use of same for regenerating neural tracts in diseases that affect the central nervous system, preferably Parkinson's disease.

A retaining pin for handling injection molded preforms includes a body including an internal body flow channel, and a plunger coupled to the body and movable relative to the body between advanced and retracted positions. The plunger includes an internal plunger flow channel. The plunger further includes a plunger abutment surface directed away from the body. The plunger is biased toward the advanced position and movable to the retracted position by engagement of the plunger abutment surface with an inner surface of a closed end of a preform when the preform and retaining pin are moved toward each other. The body flow channel and the plunger flow channel are in fluid communication when the plunger is in the retracted position. Fluid communication between the plunger flow channel and the body flow channel is inhibited when the plunger is in the advanced position.

A method is provided for molding a composite sheet in an injection molding press including a female mold tool and a cooperating male mold tool. The method includes the steps of loading the composite sheet into an open mold, positioning a heating element between the composite sheet and the female mold tool to preheat the composite sheet and a cavity of the female mold tool and removing the heating element and closing the mold.

An apparatus for cooling molded preforms may comprise a conveyor device for conveying the molded preforms and a tempering insert. The conveyor device may also comprise an extraction plate that contains a cooling cavity for receiving and cooling a closed section of a molded preform. The tempering insert may be connected to the conveyor device and be configured to temper a neck region of the preform by direct contact. The tempering insert may be designed to both temper and accommodate a preform in the conveyor device. The apparatus may further comprise a heat pipe that is configured to draw heat from the cooling cavity to cool the closed section of the preform.

A wheel, in particular a counting wheel for a meter, includes a bearing bush and a wheel rim. The bearing bush and the wheel rim are produced from different materials. The bearing bush and the wheel rim can move relative to one another in the rotational direction through a guide having complementarily corresponding guide elements on the bearing bush and the wheel rim extending continuously in the circumferential direction of the counting wheel.

Disclosed is a method of manufacturing a thermoplastic synthetic resin product, including preparing a mold having a cavity formed in a predetermined shape; filling the cavity of the mold with a thermoplastic synthetic resin material in an amount greater than the volume of the cavity of the mold; heating the mold under pressure; releasing the pressure when the thermoplastic synthetic resin material charged in the cavity of the mold is melted by heating, and opening the mold; removing, of the melted thermoplastic synthetic resin material in the opened mold, the material other than the material charged in the cavity of the mold; placing either a fabric or a hot melt on the mold having the cavity filled with the thermoplastic synthetic resin material; and cooling the mold under pressure, thus integrating either the fabric or the hot melt with the thermoplastic synthetic resin material in contact with either the fabric or the hot melt.

A method for manufacturing an injection-molded article, preferably a preform (11) of a bottle (1), in particular an aerosol bottle, made of a crystallizable polymer material, this article having at least one crystallized part (3), in particular a neck, and preferably a tubular body (14) closed at one end (16), the method comprising the following steps: a) producing an injection-molded article, preferably an injection-molded preform (11), by injecting the crystallizable polymer into a mold, b) crystallizing said part (3) of the injection-molded article, in particular of the injection-molded preform, by heating and then cooling the latter, wherein, in said method, between step a) and step b), the injection-molded article, in particular the injection-molded preform (11), is held for a sufficient duration under storage conditions such that it undergoes moisture uptake of at least 0.4% by weight.

A method for manufacturing a reel includes molding a reel configuration component that is made of resin and includes a reel hub with an outer peripheral face for winding a recording tape onto, after the molding and prior to the reel configuration component cooling and shrinking, embedding a reinforcement ring into the reel hub, and after the embedding, cooling and shrinking the reel configuration component and fixing the reinforcement ring to the reel hub.

An injection molding machine includes a machine base extending along a horizontal machine axis; a stationary platen fixed to the base; a moving platen supported by the base; a center section supported by the base axially intermediate the stationary and moving platens; at least one mold stroke actuator for translating the moving platen and the center section along the machine axis between a mold-open position and a mold-closed position; a two-stage first injection unit supported by the base behind the stationary platen for injecting a first resin through the stationary platen; and a two-stage second injection unit supported by the base behind the moving platen for injecting a second resin through the moving platen. The second injection unit is translatable along the machine axis to accommodate translation of the moving platen during movement between the mold-open and mold-closed positions.

A molding system (10) for fabricating a part comprises a first mold section (12) defining a first mold cavity (14), a first insert (16) slidable to a plurality of positions relative to the first mold cavity (14) to adjust a dimension of the mold cavity, a second mold section (20) to be disposed adjacent to the first mold section (14) to at least partially enclose the first mold cavity (14), a molding material conduit (26) to be disposed in fluid communication with the first mold cavity (14), and a positioning mechanism (18) configured to move the first insert (16) to the plurality of positions relative the first mold cavity (14).
