Patent number: 7090792Abstract: A group of multiple hollow fibers may be shaped to introduce angular divergence among the fibers, or to introduce a selected longitudinal oscillation into the fibers. In one shaping technique, the fibers are held in parallel while upper and lower crimping assemblies of parallel crimping bars are drawn together on opposite sides of the parallel fibers. When bars of the opposing assemblies draw sufficiently close, they sandwich the fibers in between them, causing each fiber to assume a shape that oscillates as the fiber repeatedly goes over and then under successive bars. Since the crimping bars are aligned at oblique angles to the fibers, the peaks and troughs of successive fibers are offset. While in this position, the fibers are heated and then cooled to permanently retain their shapes. A different shaping technique utilizes a lattice of criss-crossing tines defining multiple apertures. In this technique, the lattice and fibers are positioned so that each fiber passes through one of the apertures.Type: GrantFiled: November 2, 2000Date of Patent: August 15, 2006Assignee: Alsius CorporationInventors: David P.

Patent number: 6537476Abstract: A method for forming a spring coil in a length of hollow, cylindrical thermoplastic tubing comprises clamping the ends of a predetermined length of cylindrical thermoplastic tubing between first and second opposing spaced clamping members. The first and second clamping members then are rotated relative to one another by a predetermined amount selected to be slightly in excess of 360°, while the mandrels are simultaneously moved toward one another, to shorten the distance between the ends of the length of tubing, while the coil is formed. The clamped tube, with the coil now formed around the mandrels, is rotated and simultaneously heated to the thermosetting temperature of the tubing. After a sufficient time to establish thermosetting of the coil, the heat is removed; the tube is cooled and released from the machine.Type: GrantFiled: September 8, 2000Date of Patent: March 25, 2003Assignee: International Polymer Engineering, Inc.Inventor: Thomas E.

Publication number: 20020140125Abstract: The invention relates to a method for producing a substantially regular cylindrical body that consists of a deformable material, especially a sintered metal blank (10). Said blank is provided with an interior helical recess (12). The blank is first produced with a substantially linear course of the interior recess (12), for example by extrusion. The body (10) is cut to a defined length and is subjected to a rolling movement by means of a friction surface (18) while being supported across its entire length on a support (16). The speed of said rolling movement changes in a linear and continuous manner across the length of the body (10), thereby regularly twisting the body (10).Type: ApplicationFiled: March 11, 2002Publication date: October 3, 2002Inventor: Arno Friedrichs
