Composite joints and methods of forming composite joints are presented. A composite joint comprising: a first composite component formed of one of a thermoset material or a first thermoplastic material; a second composite component formed of a thermoset material or a third thermoplastic material; a thermoplastic joining film formed of a second thermoplastic material between the first composite component and the second composite component, the second thermoplastic material different from the thermoset material, first thermoplastic material, and third thermoplastic material; and a carbon conductive layer in the thermoplastic joining film.

The present disclosure provides systems and methods for assembling a subassembly for use in manufacturing an implantable device header. A method includes placing a first split web into a top platen, placing a second split web into a bottom platen, placing a conductor assembly and an antenna assembly in the bottom platen on top of the second split web, compressing the top and bottom platens together, heating the top and bottom platens until a predetermined temperature and a predetermined pressure are reached, such that first split web is fused to the second split web to form the subassembly, separating the top and bottom platens, and removing the formed subassembly.

A packaging machine, comprising a control unit, at least one measurement device and a plurality of work units for different processes. One of the work units is designed as a sealing station which comprises at least one moisture sensor designed as the measurement device which is functionally connected to the control unit and is designed to detect moisture within the sealing station as a time-dependent measured variable during a program sequence of the sealing station. The program sequence may comprise an evacuation process, wherein the control unit is designed to calculate a rate of change in the moisture during the evacuation process of the sealing station. The control unit may abort the evacuation process performed on the sealing station, based on the rate of change, before reaching a target vacuum pressure within the sealing station, immediately or after a specified delay time elapses.

This disclosure concerns a composite product having first and second components. At least one intermediate binding layer is located between the first and second components, and at least one electrically conductive member is located within the at least one intermediate layer. The at least one electrically conductive member is configured to generate thermal energy upon the application of an electrical current to the at least one electrically conductive member. The at least one intermediate layer is configured such that at least one characteristic of the at least one intermediate layer is altered where the thermal energy generated by the at least one electrically conductive member is above a pre-determined threshold.

A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

An object of the present invention is to provide a method of joining resin tubes, in which the degree of freedom of selecting a tube material is large, and further a defect such as stiffness and contraction at joining portions of the tubes is not developed. The method of joining resin tubes according to the present invention is a method of joining resin tubes so that a first tube is joined to a second tube, the first tube and the second tube each being made of synthetic resin, the method comprising: a surface activation step of activating each of a joining region of the first tube and a joining region of the second tube; and an adhesion step of adhering the joining region of the first tube obtained via the surface activation step with the joining region of the second tube obtained via the surface activation step to each other.

A method for improving the heat sealability of a packaging material and a method for manufacturing a heat-sealed container or package are described. The material can be polymer-coated packaging paper or cardboard, or a polymeric packaging film. The material includes a polymer layer that contains polyester, particularly polylactide, the heat sealability of which is improved by ultraviolet radiation. Polylactide is useful as such or when blended, for example, with other biodegradable polyester. The containers and packages thus manufactured include disposable drinking cups and cardboard carton and box packages.

A repair system that includes a handheld device comprising a first extruder tip having an interior passageway extending between an inlet and a tip outlet, wherein the inlet is configured to receive a solid thermoplastic material and the tip outlet is configured to dispense a fluidic thermoplastic material; a nozzle surrounding the first extruder tip to form an annulus between an interior surface of the nozzle and an exterior surface of the first extruder tip; and a heater that is configured to heat the interior passageway of the first extruder tip such that the solid thermoplastic material becomes the fluidic thermoplastic material. In some embodiments, the repair system also includes a gas source in fluid communication with the annulus such that a skirt-shaped curtain of gas extends from the annulus and in a direction towards the tip outlet of the extruder tip.

A method includes placing a first split web into a top platen, placing a second split web into a bottom platen, placing a conductor assembly and an antenna assembly in the bottom platen on top of the second split web, compressing the top and bottom platens together, heating the top and bottom platens until a predetermined temperature and a predetermined pressure are reached, such that first split web is fused to the second split web to form the subassembly, separating the top and bottom platens, and removing the formed subassembly.

A microporous battery separator is provided having a first co-extruded multilayered portion and a second co-extruded multilayered portion. The two portions are bonded together. In a preferred embodiment, the battery separator has two substantially identical multilayered portions bonded together face-to-face. Each of the two multilayered portions has at least one strength layer and at least one shutdown layer. Methods for making the battery separators are also provided. Preferably, a tubular multilayered film is extruded, and collapsed onto itself to form a multilayered battery separator precursor. The precursor is then bonded and annealed before it is stretched to form a microporous multilayer battery separator.
