Patent CA-2441264-A1 (CA)
Title: Reglage limite de rayon de courbure sur des tapis de convoyeur circulaire
Inventor: PALMAER ERIC K
IPC: B65G21/18
Filed: 2002-03-13
Abstract: L'invention concerne l'ajustement, à un rayon de courbure minimum, de tapis de convoyeur en plastique constitué de modules interconnectés par des tiges transversales, pouvant être déplacé en ligne droite ou selon une courbe, le tapis pouvant défiler grâce à une réduction du télescopage à la bordure intérieure du tapis. On obtient cet effet à l'aide de cales (62) disposées dans les ouvertures (28) des extrémités de liaisons, empêchant un déplacement complet des tiges dans ces ouvertures, à chaque rangée ou à des rangées choisies du tapis, de cales (56) placées ailleurs dans le tapis afin d'empêcher un télescopage complet, en utilisant différents modules de certaines rangées, avec moins de télescopage, ou en substituant différents modules de bordure dans des tapis à modules multiples par rangée. De cette façon, il est possible de définir un tapis de convoyeur de base possédant un rayon de courbure minimum relativement serré et qui peut être modifié sur mesure pour passer sur un convoyeur à spirale ou sur d'autres systèmes à tapis dont les rayons de courbure sont plus importants que celui du tapis de base.

Patent CA-2445698-A1 (CA)
Title: Crude oil recovery system
Inventor: TIEBEN JAMES B
IPC: E21B43/00
Filed: 2002-04-22
Abstract: A crude oil recovery system (10) includes a downhole pump (22) and an extension (60) that extends below the downhole pump (22). The extension (60) has an extension inlet (62) positioned below the lowest drawdown level (L2) achievable by the pump (22). All of the fluid pumped by the downhole pump (22) enters the extension (60) via the extension inlet (62), and by positioning the extension inlet (62) sufficiently below the lowest drawndown level (L2) achievable by the pump (22), pressurized gas (82) is prevented from entering the extension (60), the pump (22), or the pump column (40) above the pump (22). In this way, gas (82) is prevented from displacing oil (80) in the pump column (40), thereby maintaining excellent cooling for the polish rod (38), and gas (82) is confined to the borehole annulus (18), where it can readily be recovered or vented.
Patent CA-2449636-A1 (CA)
Inventor: MCGUFFEY GRANT
IPC: F04C11/00
Filed: 2003-11-17
Abstract: A new and improved gear pump assembly, and a new and improved hot melt adhesive applicator assembly having a plurality of the new and improved gear pump assemblies incorporated therein, wherein each gear pump assembly is mounted upon the applicator assembly in an entirely independent manner such that each gear pump assembly can be individually removed from the applicator assembly, and replaced back onto the applicator assembly, as may be necessary in connection with, for example, repair or maintenance procedures. The independence of each gear pump assembly also effectively prevents damage to one gear pump assembly from adversely affecting the operation of the other gear pump assemblies. Furthermore, in view of the fact that a driven gear of each gear pump assembly projects radially outwardly through an end face of the gear pump assembly so as to operatively engage a common drive shaft of the applicator assembly, as opposed to having the common drive shaft of the applicator assembly pass through side portions or faces of all of the gear pump assemblies, not only is the aforenoted independent mounting of the plurality of gear pump assemblies upon the applicator assembly facilitated, but in addition, the need for all dynamic shaft seals, normally necessarily provided between the common drive shaft and one of the gear members of each gear pump assembly, is eliminated.

Patent CA-2459964-A1 (CA)
Inventor: GRAHN FREDRIK
IPC: E21B15/00
Filed: 2002-09-13
Abstract: Method for restricting leakage of hydraulic oil in a rock drilling rig (I).  The oil level in the tank (3) is read and stored in a memory each time one switches between drilling and positioning of different components on the drill rig (I). After that the oil level is read at even intervals between the changes of operational mode. The last five read values are used for calculation of a level change velocity of the level in tank (3). The supply of hydraulic oil from pump (2) to drill rig (I) is stopped if the level in the tank has dropped a predetermined value, separately adjustable for each operational mode, or if the level change velocity exceeds a predetermined value, separately adjustable for each operational mode.

Abstract: A pulse detonation system (40) for a gas turbine engine (10) having a longitudinal centerline axis (12) extending therethrough includes a rotatable cylindrical member (42) having a forward surface (44), an aft surface (46), and an outer circumferential surface (48), where a plurality of spaced detonation passages (52) are disposed therethrough. Each detonation passage (52) includes at least a portion having a longitudinal axis (58) extending therethrough oriented at a circumferential angle (60) to the longitudinal centerline axis (12). The pulse detonation system (40) further includes a shaft (36) rotatably connected to the cylindrical member (42) and a stator (62) configured in spaced arrangement with the forward surface (44) of the cylindrical member (42) and a portion of the shaft (36).
