20080257436	Piping - The present invention relates to piping (	10-23-2008
20090044954	Method for Transporting Multiphase Fluids - A method of transporting multiphase fluids during extraction of said fluids from a well. The method includes first providing a well production apparatus. The well production apparatus includes tubing for carrying a flow of well production fluids. A centre line of the tubing follows a substantially helical path, and the amplitude of the helix is less than or equal to one half of the internal diameter of the tubing. Then, the method includes transporting multiphase fluids along the tubing whilst inducing swirl flow thereof.	02-19-2009
20090095594	CRACKING FURNACE - The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The tube is formed such that it has at least one section whose centreline curves in three dimensions, to induce swirl flow in the tube. Preferably, the tube is formed as a helix.	04-16-2009
20090218037	Piping - The invention relates to piping comprising a portion wherein the centreline of the portion follows a substantially helical path, wherein the amplitude of the helix is less than or equal to one half of the internal diameter of the piping. When fluid flows in such piping, it is made to swirl. This provides a number of advantages, such as improved in-plane mixing of the fluid, enhanced uniformity of residence time, and so on. The invention also extends to various methods of making such piping.	09-03-2009
20090235850	PIPING - The present invention relates to piping (	09-24-2009
20090276029	HELICAL STENT - An expandable balloon for insertion in a fluid conduit of a human or animal body is movable between a collapsed condition and an expanded condition. The balloon has, when in the expanded condition, a center line which follows a substantially helical path. The balloon can be combined with a stent such that the stent is expandable by the balloon from a collapsed condition to an expanded condition.	11-05-2009

20080262599	Stent - A stent for insertion in a fluid conduit of a human or animal body includes a hollow structure having generally circumferentially extending parts which have opposite end portions in the longitudinal direction. The circumferential parts are joined to a longitudinally adjacent circumferential parts along the length of the hollow structure wherein the end portions of adjacent circumferential parts are not in parallel planes and/or the end portions of the same part are not in parallel planes. Also, the non-parallel end portions are arranged along the length of the hollow structure such that a flow lumen defined by the hollow structure, and imposed on the flow lumen by the hollow structure when in the fluid conduit, follows a non-planar curve.	10-23-2008
20090293574	Artifical Graft Tubing - A method of making artificial graft tubing includes providing a helical mandrel having a centre line following a substantially helical path, and providing a generally tubular wall having a longitudinally extending cavity. The helical mandrel is positioned inside the tubular wall so that the longitudinally extending cavity has a centre line following a substantially helical path. The tubular wall is caused to retain, at least partly, the shape with the longitudinally extending helical cavity. Another method includes providing a mandrel having a substantially helical groove, and providing a generally tubular wall having a longitudinally extending cavity. The tubular wall is positioned at least partly in the groove so that the longitudinally extending cavity has a centre line following a substantially helical path, and the tubular wall is caused to retain, at least partly, the shape with the longitudinally extending helical cavity.	12-03-2009
