Granted: 2007-12-11
Abstract: Cette invention a trait à une logique de commande permettant de constater un découplage d'arbre dans un moteur à turbine. Dans le mode de réalisation préféré, la logique de commande, qui reçoit des entrées relatives à la vitesse de rotation de l'arbre et/ou à la pression du compresseur, utilise ces paramètres pour diagnostiquer un découplage d'arbre en quelques fractions de seconde avant que la turbine ne soit gravement endommagée. Cette logique de commande procède également à plusieurs échantillonnages par intervalles ainsi qu'à un échantillonnage sur plusieurs canaux afin de vérifier toute constatation de découplage d'arbre. Si celui-ci est diagnostiqué, le débit carburant cesse et le moteur s'arrête.

Abstract: Disclosed is a cleaning implement in the form of a sleeve-type self-wringing mop. In accordance with a preferred embodiment of the invention, the cleaning implement includes a shaft, a mop of a liquid absorbent material disposed at one end, and a wringer. The wringer includes a wringing sleeve that comprises a handle that is rotatable relative to the sleeve over at least a portion of the axial range of travel of the sleeve, and at least one volute. The volute has a generally helicoid surface that cooperates with a drive that is fixed with respect to the shaft, the volute and drive cooperating in the manner of a cam and cam follower. A user may advance the wringer upon grasping the handle and axially translating the handle relative to the shaft. The camming interaction between the volute and drive causes rotation of the wringing sleeve relative to the shaft to cause liquid to be expelled from the mop.

Patent CA-2358507-C (CA)
Inventor: TODD WILLIAM J
IPC: D06M11/83
Filed: 1999-02-03
Granted: 2007-10-23
Abstract: Micro-particles of transition metals or their compounds can be generated as an integral part of a textile fiber by first attaching a nucleating agent to the fiber, and then adding a solution of metal ions. The ions are reduced by the nucleating agent in the fiber, and micro-particles are generated in or on the fiber. Because of the strong color signal resulting from a low concentration of metal micro-particles, the method is cost effective even when using gold or titanium ions. Various colors were generated by changing the size and spacing of the micro-particles, the metal or metal complex used, and the characteristics of the textile. The dyed textile displayed colors ranging from pink, red, purple, yellow, orange, peach, brown, gold, silver, grey, green, and black.  These colors resisted bleaching by either chemicals or light.
