Patent CA-2536668-A1 (CA)
Title: Braided spar for a rotor blade and method of manufacture thereof
Inventor: VIOLA KEVIN
IPC: B29C70/22
Filed: 2004-08-20
Abstract: A braided rotor blade spar includes a tri-axle braid in which braided bias angled fibers are located non-parallel to a longitudinal axis of the spar.  Zero degree fibers are located parallel to the axis and are positioned to be on the upper and lower surfaces of the spar. The bias angle fibers are braided around the zero degree fibers. In a method of manufacture of the braided spar, a braided sleeve is formed dry over a mandrel by a multi-axial braiding machine. Once the braided sleeve is formed upon the mandrel, the mandrel is located within a matched metal mold, resin impregnated, and cured. The mandrel is then removed from the finished braided spar.

Inventor: CRAIG STEPHEN
IPC: A01K67/033
Filed: 2004-10-29
Abstract: The present invention provides a method for inducing gamete maturation in marine worms of the family Arenicolidae and which exhibit epidemic spawning.  In the method, male and/or female worms in a housing substrate (such as sand) in sea water are maintained at a temperature of 4 to 8~C for 14 to 24 days, preferably 5 to 7~C for 20 to 22 days. Spawning of the worms can then be induced either by exposure to suitable spawning promoting hormones or by raising the temperature of the sea water to 12 to 14~C.

IPC: H04B10/08
Filed: 2006-07-12
Abstract: A fault location system (FLS) for a hybrid fiber coax (HFC) cable network. The FLS comprises an interactive map, a datastore, an object generator, and a display server. The datastore receives identifying information and status information of customer premises equipment (CPE) units connected to the HFC cable network. The object generator associates the identifying information and the status of CPE units with an object and further associates graphical attributes with the object. The display server graphically displays the object on the interactive map at location coordinates indicative of the street address, and graphically displays the object according to its graphical attributes. When used with a processor, the FLS applies algorithms to non-responsive CPE units selected from the interactive map to identify possible common sources of a fault.

Abstract: Refractory or hard sulfur found in a hydrocarbon stream containing refractory sulfur heterocycle compounds, particularly those exhibiting steric hindrance, is removed from the stream by contacting it with a sodium reagent comprising a sodium component, having free sodium, supported on a solid support component.  If the hydrocarbon stream contains more labile or easy sulfur, then it is treated, typically by hydrodesulfurization, to remove at least most of the labile sulfur before it is contacted with the sodium reagent. This is useful for bringing the sulfur level of middle distillate fuel streams, such as diesel and jet fuel fractions, down to a level of less than 10 wppm, employing conventional hydrodesulfurizing catalysts and conditions.

IPC: A61F2/24
Filed: 2005-09-14
Abstract: The prosthesis (100) includes a pocket (106) formed from flexible material (104) disposed on a ring (102). When properly oriented in a mitral valve (120) of a heart (124), the pocket (106) expands as the mitral valve closes, blocking any openings between the mitral valve leaflets (122). During systole, backpressure from the blood in the left ventricle (128) presses against the mitral valve leaflets (122), as the papillary muscles move these leaflets (122) to a closed position. The mitral valve leaflets (124) coapt against the expanded pocket (106), minimizing or even eliminating gaps that would otherwise be present between the two leaflets (122).
