Abstract:
A process for making a crosslinked assembly includes steps of: selecting a desired performance parameter for a molded assembly of a first polymeric component and a second polymeric component bonded to the first polymeric component, controlling a first crosslinking percentage for the first polymeric component and a second crosslinking percentage for the second polymeric component independently to provide the desired performance parameter for the assembly, orienting the assembly at an angle between an orientation axis of the assembly and a electron beam direction, exposing the oriented assembly a predetermined number of times (N) to the electron beam operable to deliver a predetermined amount of radiation (R) in the electron beam direction providing a total radiation exposure proportional to (N×R) providing the first component crosslinking percentage and the second component crosslinking percentage, the resulting assembly having the desired performance parameter.

The invention relates to a joining device (10, 20) and to a method for operating a joining device (10, 20), wherein a component (12, 22) comprising at least two parts is processed by means of an energy beam in such a way that the at least two parts are joined in a joining region by means of the energy beam, several components (12, 22) being fed and processed in succession by means of a conveying device (11, 21), characterized in that the energy beam by means of which the particular component (12, 22) is processed is moved along the joining region in dependence on the motion of the component (12, 22).
Abstract:
The present application discloses a multi-layered composite pad including at least two layers of resilient element and at least one layer of carrier substrate, wherein at least one carrier substrate layer is positioned between two adjacent resilient elements, and the carrier substrate and resilient element are bound to each other through a joining element, wherein the joining element joins the carrier substrate and its adjacent resilient element.
Abstract:
The invention is directed to an apparatus for heating an elongate tubular article, comprising a frame member adapted to be disposed around said article, a heater with multiple heating zones and a controller for operating the heating device. The apparatus may be used to apply a heat shrinkable sleeve around a welded pipe joint. The heater may be infrared and also may use thin stamped sheets. If a heat shrinkable sleeve is used, the controller may activate the heating zones from the centre of the weld outward to eliminate pockets of air. The diameter of the interior of the frame may change along the length of the frame.

Abstract:
A flexible imaging belt seam treatment article comprising a high-temperature-resistant flexible substrate that supports a thermoplastic polymer film. The film is deposited on the flexible substrate by dissolution of a film-forming thermoplastic polymer in a carrier solvent, applying the resulting solution to the flexible substrate, and eliminating the carrier solvent. The article can then be used to treat a seam of a flexible imaging belt by placing it on the seam, heating the strip and seam, and applying pressure to the strip and seam.
Abstract:
A heating element assembly in the form of a heating tray and a method of manufacturing heating tray assemblies. The heating tray may be used for defrosting and heating pans such as so-called nullhalf-pansnull of frozen food products. The preferred heating tray is configured to fit precisely around a standard thin foil half-pan container, thus optimizing heat transfer between the heating tray and the food product. The varied surface watt density of the heating tray allows for accurate heat placement such that the food product can be evenly warmed while avoiding over warming or burning, particularly at the corners and edges. A preferred embodiment of the heating tray includes two resistance heating elements. The first heating element is a temperature booster used for defrosting and heating, while the second heating element is a maintenance heater to maintain heated food at a serving temperature.

Abstract:
A belt seam treatment apparatus includes a support element with a smooth surface that supports the seam region of the belt, a heat source that heats a treatment strip and the belt seam region, and a pressure applicator that forces the treatment strip against the belt seam region. The support element can be a tube over which the belt hangs and can include a vacuum belt hold system that secures the seam region against the tube during treatment. The heat source can be an infrared laser or an infrared lamp. Optics form a heat spot or a heat line on the strip and seam region, and a pressure wheel traverses the seam region after heating to compress the strip and seam and bond a thermoplastic polymer of the strip to the seam region of the belt.
