A method for bonding a contact surface of a first substrate to a contact surface of a second substrate comprising of the steps of: positioning the first substrate on a first receiving surface of a first receiving apparatus and positioning the second substrate on a second receiving surface of a second receiving apparatus; establishing contact of the contact surfaces at a bond initiation site; and bonding the first substrate to the second substrate along a bonding wave which is travelling from the bond initiation site to the side edges of the substrates, wherein the first substrate and/or the second substrate is/are deformed for alignment of the contact surfaces.

Fluid flow conduits and apparatus and methods for joining the conduits, preferably in a sterile manner, are disclosed. Each conduit has a polymeric open end that is sealed by a sealing member that may include a heating element. The polymeric end material is melted, the sealing members are moved to expose the melted open ends of the conduits and the ends are brought together to form a fused or welded connection between the conduits.

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 bonding system includes a heating element, an actuator, an infrared camera, a pressure sensor and/or a displacement sensor, one or more processors. and a computer readable medium storing instructions that, when executed by the one or more processors. cause the bonding system to perform functions including providing a first control signal to a heating element. thereby heating a workpiece with electromagnetic radiation having one or more oscillation frequencies within a range of 1 MHz to 2.00 MHZ. and providing a second control signal to an actuator. thereby applying a pressure to the workpiece via the actuator. The functions also include detecting a temperature of the workpiece. the pressure applied to the workpiece. and/or a displacement of the actuator, and adjusting the first control signal and/or the second control signal based on the temperature of the workpiece. the pressure applied to the workpiece, or the displacement of the actuator.

The present invention relates to a structure including a layer including titanium (di)oxide nanostructures, such as titania nanotubes, in contact with a membrane layer including a proton-conducting polymer. A process for preparing the structures of the invention is presented wherein titanium (di)oxide nanostructures on a first substrate are transferred to an ion-conducting polymer membrane by pressing using a hot press, and then detaching the nanostructures from the first substrate.

A method for forming a geomembrane liner testable for leaks by securing adjacent panels together with the conductivity of the lower surface of an overlying panel broken along a line adjacent the panel overlapping edge, and the overlapping edges sealed along the line. A heat welder has slots for the overlapping panel edges, with a heated wedge between the slots and having a projection to break the conductivity of the overlying panel bottom surface as it passes the wedge. The slots merge to press the liner edges together to heat weld them along the line of broken conductivity as the welder is moved along the panel edges.

Two composite laminates are joined together by a bondline having portions exposed to the ambient environment. The bondline contains scrim having an electrical conductivity and impedance matched to that of the laminates in order to mitigate effects of lightning strikes.

Polymer compositions containing a polyoxymethylene base polymer that is compounded with a conductive filler and pigment carbon black are disclosed that exhibit electrostatic dissipative (ESD) capabilities while also being laser weldable. The polymer composition can be formed into shaped or molded articles such as filters, flanges, connectors, etc. for use in fuel systems where conductivity, ductility, weldability, and resistance to aggressive fuels are required. The compositions can be compounded into a pellet product which can then be formed into a shaped article that complies with the ESD capabilities required by SAE J1645. At the same time, parts produced from the compositions can absorb laser energy sufficiently to form a high quality welded interface with parts produced from other compositions that are transparent to laser radiation and cannot absorb laser energy sufficiently.
