A composite component includes a component body and a datum feature. The datum feature projects in a first direction from a surface of the component body; the component further includes a plurality of pins extending generally in the first direction so that a first end of each pin is engaged in the component body and a second end of each pin is engaged in the datum feature. The datum feature is removable from the component so as to leave the first ends of the pins engaged with the component body. The first ends of the pins may be used to identify and locate the position of the original datum feature, when the component requires repair or other attention.

A method and apparatus for assembling a high purity liquid distribution system is described. A distal end portion of the tube is heated then pushed over a sleeve so that the distal end portion can have a shrink seal fit over the sleeve to mitigate accidental or inadvertent pull out of the tube from a fitting. Other benefits are also achieved such as minimal flow restriction of the liquid flowing through the joint and the tube.

Composite joints and methods of forming composite joints are presented. A composite joint comprising: a first composite component formed of one of a thermoset material or a first thermoplastic material; a second composite component formed of a thermoset material or a third thermoplastic material; a thermoplastic joining film formed of a second thermoplastic material between the first composite component and the second composite component, the second thermoplastic material different from the thermoset material, first thermoplastic material, and third thermoplastic material; and a carbon conductive layer in the thermoplastic joining film.

This invention discloses a multi-layer film for making pouches for containing flowable materials, said multi-layer film comprising generally five layers in order: inner sealant-layer, first interposed layer, the core layer, second interposed layer, and the outer sealant layer. The sealant and core layers are ethylene-based, whereas the interposed layers are polypropylene-based. The multi-layer film thickness is in the range of from about 35 microns to about 66 microns. The combined thickness of the first and the second interposed layers is in the range of from about 10% to about 27% of the total thickness of said multi-layer film. Similarly, a combined thickness of the inner and the outer sealant-layers is in the range of from about 10% to about 27% of the total thickness of the multi-layer film. The interposed layers comprise polypropylene that has a melt-index of less than 0.75 dg/min.

Pressurized air is conveyed through a manifold into contact with the first member via apertures having hole diameters of from 0.8 to 2.5 mm that are spaced apart at a distance of from 10 to 30 mm along the manifold to achieve a turbulent air flow pattern with a Reynolds number of greater than 2200 at a temperature of between 150 and 315 C. and at an air pressure between 0.5 and 10 pounds per square inch (psi) over ambient pressure onto the outer surfaces of the first member and the second member for heat curing a curable adhesive between the members to achieve adhesive cure in 60 to 90 seconds and free of any bond-line read-out visible to an unaided normal human eye.

A conduit, such as an introducer sheath, catheter, or guide catheter, incorporating two or more separate lumens to prevent the entanglement of guidewires located at least partially within the conduit. The lumens are separated by at least one disruptable barrier that allows multiple lumens to be converted into fewer lumens prior to or as a device is advanced through the introducer sheath.

The invention relates to a method for producing flexible tube bodies (18) for packaging tubes from a film substrate (1) which has a print, preferably on an outer side (2), and which has or consists of at least one weldable plastic layer and which comprises a first longitudinal edge side (8), which extends in a longitudinal direction, and a second longitudinal edge side (8) parallel thereto and spaced apart therefrom, wherein the film substrate (1) is shaped by shaping means (23) to form a tube, and the two longitudinal edge sides (8, 8) are in particular welded to one another with the formation of a longitudinal weld seam, wherein a strip (12) is arranged, in the region of the abutment point and/or of the longitudinal weld seam, in the interior (17) of the film substrate (1) shaped to form the tube and is connected, in particular welded, to the longitudinal edge sides (8, 8) at least in certain regions or portions. According to the invention, prior to the formation of the longitudinal weld seam, at least one longitudinal edge side (8) is shaped, in particular cut, in such a way that, in the film substrate (1) shaped to form the tube, the longitudinal edge sides (8, 8) bear against one another, in particular in abutting fashion, radially only in the region of the outer side (2) with at least one tip (9) formed by the shaping operation.
