The present invention relates to a computer implemented method for determining a weld integrity test result performed by a system configured to aseptically transferring cells to a container (BR), the method comprising welding (710) a vial to a connector to obtain a fluid-tight seal between the vial (V) and a connector (C), the connector being provided with a pair of conduits each having one end protruding through the connector and into the vial, sealing (720) an opposite end of one of the conduits, generating (730) a fluid pressure different to an ambient fluid pressure at an opposite end of the other conduit, measuring (740) a fluid pressure within at least one of the conduits, determining (750) a fluid pressure change based on the ambient pressure and the measured fluid pressure, determining (760) the weld integrity test result as pass or as fail based on the fluid pressure change.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.

A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

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.

A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

A pipe elbow has a first end and a second end off parallel to the first end. An interior surface of the pipe elbow has a centerline having an arcuate portion. A circular cylindrical exterior surface portion of the pipe elbow surrounds the arcuate portion of the centerline.

The disclosure relates to a component device, in particular for a primary supporting component of an aircraft, the component device having a first component element, a second component element, a bonding providing a connection between the first component element and the second component element, and a detector device having at least one interior space sensor device configured to measure a change in a pressure and/or a concentration of a gas surrounding the interior space sensor device. The first component element, the second component element, and the bonding confine an interior space. The interior space sensor device is arranged in the interior space.

A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. The faying surfaces of the flanges of the top and base have portions in the shape of a hollow truncated cone. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements.

The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment is composed of a polymeric composition. The polymeric composition includes (i) from 70 to 90 weight percent of a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.970 g/cc, a melt temperature, Tm, greater than 125 C., and a melt index from 1 g/10 min to 50 g/10 min; and (ii) from 30 to 10 weight percent of an oletin based elastomer having a density from 0.860 g/cc to 0.905 g/cc, a melt index from 0.2 g/10 min to 50 g/10 min, and a Tm less than 125 C.

A system for in-line controlling of the ultrasonic welding of plastic components of an electronic cigarette, in which plastic components are welded to one another at a welding zone to define a welded group; the plastic components are such that the welded group has an air passage duct having a first open end and a second open end. The system includes: a chamber for receiving the welded group; a closure for closing the first open end; air supply for supplying air into the chamber. The system further includes an air exit, connecting the welding zone with the outside of the chamber; a continuous pressure control and adjustment for continuously controlling and regulating the air pressure that enters the air passage duct to keep a fixed air pressure; an air passage nozzle having a predetermined cross section, position between the continuous pressure control and adjustment and the second open end; and a pressure sensor for detecting the air back pressure generated in the chamber after the introduction of air into the air passage duct.
