System and method for bubble-free gas-enrichment of a flowing liquid within a conduit
The present invention provides a system for enriching a flowing liquid with a dissolved gas inside a conduit. The system comprises two or more capillaries, each capillary delivering a stream of a gas-enriched liquid to the flowing liquid. The first ends of the capillaries are positioned to form an intersecting angle with respect to the effluent streams such that these streams of gas-enriched liquid collide with each other upon exit from the first ends of the capillaries, effecting localized convective mixing within the larger liquid conduit before these gas-enriched streams are able to come into close contact with the boundary surfaces of the conduit, whereby the gas-enriched liquid mixes with the flowing liquid to form a gas-enriched flowing liquid. In the preferred embodiment, no observable bubbles are formed in the gas-enriched flowing liquid. Methods of making and using such system are also provided.

MARKED FLUOROPOLYMER SURFACES AND METHOD OF MANUFACTURING SAME
A method of manufacturing a coated low-friction medical device, such as low-friction medical tubing, including applying a coating to one or more selected portions of a surface of low-friction medical tubing to indicate at least one marking formed along the surface of the low-friction medical tubing, and simultaneously or substantially simultaneously: (a) curing the applied coating to a designated temperature (which is above the temperature at which the low-friction medical tubing begins to decompose and shrink) to adhere the applied coating to the surface of the low-friction medical tubing, (b) utilizing one or more anti-shrinking devices to counteract or otherwise inhibit the shrinking of the low-friction medical tubing, and (c) exhausting any harmful byproducts resulting from curing the low-friction medical tubing to a temperate above the temperature at which the low-friction medical tubing begins to decompose.
SYSTEMS AND METHODS FOR LINER BRAIDING AND RESIN APPLICATION
A method of selecting a braid configuration for a braided liner. The method includes calculating a size ratio based on the smallest first diameter and the largest second diameter of the liner and selecting a braid material having a tensile strength. The method further includes calculating a strength ratio based on the tensile strength of the braid material and a selected target strength threshold for the braided liner and determining an optimal braid angle for the smallest first diameter portions of the liner based on the calculated size ratio.
SYSTEMS AND METHODS FOR LINER BRAIDING AND RESIN APPLICATION
A method of making a tank for storing fluid that includes generating a resinated braid layer on an elongated liner having a plurality of successively alternating rigid and flexible portions along the length of the liner. Generating the resinated braid layer on the liner includes feeding the liner into a braiding machine and applying resin to a plurality of fibers during a braiding process to generate a resinated plurality of fibers and generating, over a length of the liner, by the braiding machine, the resinated braid layer defined by the resinated plurality of fibers.
METHOD FOR PRODUCING A BENT THERMOPLASTIC COMPOSITE, A BENT THERMOPLASTIC COMPOSITE AND A SYSTEM FOR MANUFACTURING A BENT THERMOPLASTIC COMPOSITE
The invention relates to a method for producing a bent thermoplastic composite, comprising 35% or less in volume of a polymeric matrix including (meth)acrylic polymers, and at least 65% in volume of fiber, where the method includes (a) a step of providing the thermoplastic composite; (b) a step of heating a portion of the thermoplastic composite, said heating being selected between, conduction, radial and/or volumetric and the heating duration and/or the heating temperature being selected according to at least the thickness of the thermoplastic composite; (c) a step of creating a bent section in the heated portion by bending the heated portion; and (d) a step of cooling the bent section to solidify it and to form a bent thermoplastic composite, at a cooling temperature and/or a cooling duration selected in accordance with the glass transition temperatures (Tg) of the bent thermoplastic composite.

Method for roll-bending a profile, profile, method for manufacturing bent profile workpieces, bent profile workpiece, device for roll-bending a profile, and extrusion and roll-bending line
The invention relates to a method for roll-bending a profile which comprises at least one cross-sectional region which is formed from a plastics material which is shaped by extrusion. A first and a second bending roller set are provided, each including bending rollers which are arranged in such a way that a passage, which enables guiding of the profile, is formed between the bending rollers of each of the bending roller sets. The profile is bent about a first bending axis and about a second bending axis which is non-parallel thereto, the translations and rotations of the second bending roller set being brought about simultaneously at least at times and/or mutually offset in time in a predetermined sequence.
