Elastomeric articles, such as gloves, are made by welding together two plies of a multi-layer film. The film plies are welded together through ultrasonic bonding, thermal bonding, or mixtures thereof. The multi-layer film includes at least three layers that, in one embodiment, are coextruded. Each layer of the multi-layer film is made from a different composition that produces layers having different properties.

Provided herein are methods for the modulation of appearance or material properties within items of apparel or equipment. Also provided herein are design articles having alterable designs.

A system for coupling at least one component to a blade of a gas turbine engine includes a blade holder and an intensifier tool. The intensifier tool includes a plate configured to contact the component and a heating device coupled to the plate. The system further includes an adhesive layer disposed between the component and the blade, a pressure strip coupled to the plate and the blade that fully encloses the plate, and a pressure applicator coupled to the plate. The adhesive layer has a uniform bond thickness along a length of the component due to pressure applied by the pressure applicator. Upon being heated by the heating device, the adhesive layer is cured, thereby coupling the component to the blade.

A syringe includes a syringe body, a syringe cone having a distal opening, and a connection arranged in the region of the syringe cone, wherein the syringe body includes a first material and the connection includes a second material, and wherein the first material is different from the second material and the second material is a softer material than the first material.

A tool is provided for machining an interface between coplanar first and second layers of a workpiece that defines an orifice extending at least partially through the first and second layers and intersecting the interface. A housing portion includes a first end, a longitudinally-opposed second end, and a peripheral surface extending therebetween. The housing portion is configured to rotate about its longitudinal axis and extend at least partially through the orifice. A contacting element operably engaged with the housing portion between the first and second ends and proximate the peripheral surface is movable between stored and operating positions. The contacting element is configured to extend outwardly from the peripheral surface of the housing portion to operably engage the interface within the orifice when the contacting element is in the operating position. An associated method is also provided.

The present invention relates to an internal trim part for a vehicle, comprising at least two layers. A decorative skin (1) forms an upper layer and has a depression (3), in which a decorative element (8) is arranged. The decorative element (8) is connected to the decorative skin (1) by means of a bonded connection, such as a weld seam, in particular an ultrasonic weld seam (16). The invention further relates to a method for producing an internal trim part and to a device for performing said method.

A method for manufacturing a hose/connector assembly of polymeric material includes the steps of: providing a flexible hose of a first thermoplastic material; providing the connector of a second thermoplastic material having a hardness greater than the first thermoplastic material and a first end for coupling with a liquid source and a second end with a seat for receiving one end of the hose; translating the end of the flexible hose to engage the seat of the connector; rotating the connector to cause a rotational friction welding with the flexible hose; and periodically comparing the welding torque with the maximum allowable torque for the hose and the connector. The step of rotating the connector with respect to the hose is interrupted if the welding torque is equal to or greater than the maximum allowable torque.
