A leak detection sensor including a dielectric substrate including a circuit board material; and a plurality of electrical circuits in communication with the substrate, where the plurality of electrical circuits are located on different sides of the substrate.

Leak detection system and method of making and using the same

Systems and methods are disclosed that include an additive manufacturing assembly having a printing area, a first nozzle comprising a first nozzle having a first aperture diameter and configured to dispense a first material in the printing area, and a second nozzle comprising a second nozzle having a second aperture diameter that is larger than the first aperture diameter and configured to dispense a second material in the printing area.

Additive manufacturing assemblies and methods

A composite tube includes a first layer including a thermoplastic polymer having a Tg of not greater than about 160&#xb0; C. and a second layer adjacent to the first layer, the second layer including an extruded silicone material. Further included is a method of forming the composite tube which includes providing a first layer including a thermoplastic polymer having a Tg of not greater than about 160&#xb0; C.; receiving, by an extrusion system, a silicone material; forming, by the extrusion system, a second layer including the silicone material adjacent to the first layer; and irradiating the silicone material with a radiation source to substantially cure the silicone material.

Composite tubing and method for making and using same

The present disclosure relates more to processes for making a filter element that includes a filter membrane having a strip of thermoplastic polymer material laminated thereto, for example, as a strip along an edge of the filter membrane. For example, one such process includes providing a sheet of filter membrane having a first surface and an opposed second surface; providing a strip of thermoplastic polymer material having a first surface and an opposed second surface; contacting the first surface of the strip of thermoplastic polymer material with the first surface of the filter membrane; and softening the strip of thermoplastic polymer material at at least its first surface by irradiation with laser radiation; such that the softened polymer material of the first surface of the strip of thermoplastic polymer material bonds to the first surface of the filter membrane upon hardening.

Process for making a porous filter element, porous filter elements made thereby, and filter devices including them

A composite tube includes an inner layer including a silicone polymer, wherein the inner layer has a surface that defines a central lumen of the composite tube; an adhesive layer adjacent to the inner layer, wherein the adhesive layer includes an adhesive silicone material including a silicone polymer and an adhesion promoter, and an outer layer adjacent to the adhesive layer, wherein the outer layer includes a thermoplastic polymer having a functional group that forms a chemical bond with the adhesion promoter of the adhesive silicone material.

Silicone tube structures are formed having a particular dimensional accuracy. In one embodiment, a silicone tube structure can include an extruded hollow body having an inner bore. The extruded hollow body can have an inner diameter, an outer diameter, and a length of at least approximately 20 m. The extruded hollow body can also have a dimensional accuracy that is measured by the standard deviation of the inner diameter being no greater than approximately 0.8% of an average inner diameter of the extruded hollow body over the length. In an embodiment, the silicone tube structure can be cut to form a number of silicone tubes.
