Patent CA-2379252-C (CA)
Title: Flame simulating assembly
Inventor: STINSON KELLY
IPC: F21S10/04
Filed: 2002-03-26
Granted: 2008-02-12
Abstract: The invention provides a flame simulating assembly for providing an image of flames transmitted in a fluctuating light. The flame simulating assembly has a simulated fuel bed, a light source, a screen disposed behind the simulated fuel bed for diffusing and transmitting light, and a flicker element for creating the fluctuating light, the flicker element being positioned in a path of light from the light source. The simulated fuel bed defines a profile viewable by an observer. In addition, the screen includes a curved portion which is curved in a vertical direction and in a horizontal direction to correspond to the profile of the simulated fuel bed. Also, the curved portion of the screen is positioned adjacent to the simulated fuel bed. The fluctuating light transmitted through the screen is attenuated and a three-dimensional image of flames appears to curve around the profile of the simulated fuel bed.

Title: Diamond-shaped fluid powered linkage, system and engine
Inventor: STRAIN DAVID
IPC: F15B3/00
Filed: 2000-12-20
Granted: 2007-11-20
Abstract: A fluid powered linkage (12) has at least three side plates (18) of substantially equal width joined by connectors (17) to form a polygon of variable cross sectional area. An upper plate and a lower plate enclose a variable volume within the polygon. At least one port (37) allows fluid to enter into or leave from the enclosed variable volume in a controllable manner. Seals prevent fluid from entering or leaving the enclosed variable volume other than through the one or more ports. Two abutments (19, 11) are located on the side plates or connectors and the distance between the two abutments varies non-linearly with, but in the same direction as, the variable cross-sectional area. Optionally, an inner surface of one or more of the side plates defines a recess. A preferred linkage has a cross-section in the shape of a diamond or rhombus of varying internal angles, or a half or quarter thereof. In use, the obtuse angle preferably ranges from nearly 180 degrees to about 135 degrees. The linkage is used in an apparatus for producing a fluid output with altered pressure, volume or flow compared to a fluid input and a hydraulic motor.

Abstract: L'invention concerne une tarière à roche sans pas servant au forage de trous de poteau au travers de roches par pression hydraulique, avec une faible vitesse de rotation. Ladite tarière à roche est employée avec une tarière filetée habituelle servant au forage de trous de poteau dans des déblais et de l'argile. Lors d'un forage de trou de poteau, la tarière à roche remplace la tarière filetée habituelle pour le forage et l'extraction de roches ou d'autres matériaux durs du le trou de poteau. Ladite tarière à roche est conçue pour être utilisée à des vitesses de rotation très faibles et peut fonctionner avec le seul poids de la tarière. Cependant, ladite tarière à roche est également conçue pour être utilisée avec des unités de forage sous pression, et dans le but de forer un trou circulaire dans la roche et de créer un bouchon destiné à être logé dans la cavité du cylindre de la tarière à roche devant être retiré du trou de poteau. L'assemblage rapide permet de relier rapidement l'arbre d'une unité de forage sous pression à la tarière sans pas devant remplacer rapidement la tarière à roche de manière à extraire rapidement des déblais tendres du trou de poteau. Un trépan pilote peut être disposé dans la tête de coupe de manière qu'il s'étende vers l'extérieur en saillie par rapport à la tête de coupe afin d'attaquer le trou, casser de la roche, et maintenir la tarière en position lors du forage. Une partie du corps cylindrique peut être retirée afin de dégager rapidement le bouchon.

Abstract: A water-based polymer drilling fluid, containing effective quantities of surfactants having HLB numbers equal to or greater than approximately 7, emulsifies oil and bitumen contained in oil sand cuttings, resulting in the oil and bitumen being dispersed into the mud as an emulsion. This eliminates or significantly reduces the ability of the oil, bitumen, and cuttings to clog the well or stick to drill string components when drilling a well through oil-bearing sands, particularly sands containing highly viscous oil or bitumen. The emulsification process separates the sand particles from the oil and bitumen, such that the sand particles can be removed when the mud is run through a conventional shale shaker or other suitable apparatus.
