A heat sink for use in induction welding includes a number of tiles, wherein the tiles are electrically non-conductive and have a thermal diffusivity of greater than about 25 mm2/sec. A joint flexibly joins the tiles together.

A device for positioning in the body of an animal, the device comprising a first portion and a second portion that may be positioned in contact with one other, the first portion and the second portion each comprising a biocompatible conductive thermoplastic material, such that when the device is positioned in the body of an animal and electric current flows from the first portion to the second portion, heat is generated by electrical resistance at the point of contact between the first portion and the second portion so as to melt regions of the first portion and the second portion, and when the electric current is thereafter terminated, the melted regions of the first portion and the second portion re-solidify so that a weld is formed between the first portion and the second portion.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) using an induction coil includes forming a weld interface area between the first TPC and the second TPC, cooling the first TPC with a cooling apparatus before heating by the induction coil, and inductively heating the weld interface area with the induction coil after cooling the first TPC.

Conductively coated fastening systems are disclosed herein. An apparatus includes a fastening system and a structural assembly. The structural assembly comprises a first structural element made of an electrically conductive fiber reinforced plastic and a second structural element. The first structural element comprises a first hole and the second structural element comprises a second hole. The first and second holes are separately pre-formed prior to assembly of the structural assembly. The structural assembly further comprises an electrically conductive gap filler applied to a first structural element sidewall of the first hole of the first structural element. The fastening system comprises a fastener comprising a head and a shank extending from the head. The shank is configured to be inserted into the first hole and the second hole.

A reusable surgical implement or template is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable rigid, and optionally flexible material to enable the implant to conform to the desired use for the implement in a surgical procedure. The material forming the enclosure is also stretchable and flexible to accommodate the configuration and/or any flexing of the core, and is biologically inert to enable the implant to be sterilized after use for use in subsequent surgical procedures while protecting the material forming the core. The enclosure can be molded around the core in separate portions or components using multiple molding steps to form an enclosure with the desired attributes. The enclosure can also be preformed and the core inserted and secured within the enclosure using an adhesive to form the implement in an alternative manner.

The disclosure relates to a system and method for automatic sorting of natural intestines/casings for use in the production of food products, and especially as casings for sausages. A partly hollow feeding mandrel is configured to hold an intestine such that the intestine surrounds the feeding mandrel. The feeding mandrel includes a measuring area configured to transport water through a hollow part of the feeding mandrel through punctures in a surface of the measuring area, and into a cavity of the surrounding intestine. A vision device obtains images of the intestine, and a processor processes the images to sort the natural intestines or casings.

A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

A vibration welding device having a mechanically coupled multiple vibrator. Within this vibration welding device, the plurality of vibration units are arranged relative to an elongated tool such that the first direction of vibrations of the individual vibration units is oriented approximately transverse to a longitudinal axis of the tool such that, during a vibration welding process, two components are weldable to each other by vibrations different than a longitudinal direction of the components.
