Title: Dual downhole injection system utilizing coiled tubing
Inventor: VON PLAHN SHELDON
IPC: E21B47/04
Filed: 1998-03-31
Abstract: A dual injection system for selectively injecting a treating fluid in a predetermined treating zone (16) of a well bore hole (10) adjacent a productive zone (14) with a marker fluid injected from the annulus (36) outside a coiled tubing string (34). The coiled tubing string (34) is inserted within the well bore hole (10) and a sensor (40) is provided on the coiled tubing string (34) with a lower end portion (42) extending below the sensor (40) for the discharge of the treating fluid from the lower end (44) of the extending end portion (42). The sensor (40) senses a detectable material, such as a radioactive material in the marker fluid injected from the annulus (36) outside the coiled tubing string (34) and may be reciprocated within the well with the coiled tubing string (34) for determining the interface (46) between the marker fluid and the treating fluid so that the treating fluid does not enter the productive zone (18). In one embodiment (Figure 4) the productive zone (14A) is located below the treating zone (16A) and the treating fluid contains the marker to provide the marker fluid.

Patent CA-2237880-A1 (CA)
Inventor: KRISTINSSON OSSUR
IPC: A61F2/80
Filed: 1996-11-14
Abstract: The combination of compression pressure casting or molding a preformed, moldable, hardening socket material (36) and applying tension to a residual limb (40) in a distal direction while the socket material is curing results in forming a definitive socket that fits well to the residual limb after curing without substantial rectification. Pressure relief formations (90), socket coverings (92, 94), and a prosthesis coupler (38) may be compression molded simultaneously with the socket. A  pressure casting system includes a pressure chamber (20), a compressive pressure applying membrane (22), a tension reacting system (58) for producing a resultant axial tension in the residual limb within the socket material during forming and hardening of the socket, and optionally a load cell (84) to monitor or indicate the tension force during molding. The socket material includes a preformed tubular sleeve like reinforcement web of fibers pre-impregnated with an uncured preferably water activatable, moldable, hardening resin material, with an integrated prosthesis coupler at one end.

Title: A method of applying a mixture of two liquid components
Inventor: FAIRBROTHER JOHN E
IPC: B05D1/02
Filed: 1996-12-06
Abstract: A method of applying a mixture or two liquid components kept in their respective container (19) implies that the two components are expelled through their respective outlet (8, 9) of their respective outlet channel (5, 6) in a nozzle head (1) while a gas is simultaneously expelled through a separate outlet (10) in a gas outlet channel (7) in the nozzle head (1). The above outlets (8, 9, 10) are aligned along a substantially rectilinear line, the gas being expelled through the outlet (10) at one end of the line of outlets, and where the volume flow of the gas is adapted to the volume flows of the components in such a manner that outside the nozzle (1) said components are sucked into the jet being expelled through the gas outlet.

IPC: F21V29/15
Filed: 1998-08-05
Abstract: A luminaire for below-grade use comprises three primary components: 1) a top; 2) a lamp housing; and 3) a bottom.  The top comprises a lens and a lens frame, and may include additional components.  The lamp housing can be molded in various depths to accommodate various lighting systems, and is frusto-conical with the outer periphery of its bottom larger than the outer periphery of its top.  The bottom includes a junction box and a ballast box. The top is secured to the top of the lamp housing, and the bottom is secured to the bottom of the lamp housing, such that the top, bottom, and lamp housing form a lamp housing cavity which houses a lighting system.  Both the junction box and the ballast box are covered to separate them from the lighting system.  Electrical wiring connects the lighting system to the ballast assembly, and the ballast assembly to field wire splices.          Electrical wiring also exits the junction box through a conduit to connect to an external power supply, and may exit through another conduit to connect to another luminaire or the like.

Patent CA-2247233-A1 (CA)
Inventor: MIER-LANGNER ALEJANDRO
IPC: F21V7/22
Filed: 1998-09-11
Abstract: A lighting fixture or luminaire optimizes the performance of a multi-tube fluorescent lamp by orienting the lamp in a horizontal position while focusing the omnidirectional output from the lamp. A novel swivel assembly enables the lamp to move as a single unit with the reflector housing, thereby to maintain the alignment of the lamp tube to the reflector surface while allowing aiming of the light beam. In one embodiment of the invention, a socket housing snap fits into the reflector housing so that the lamp rotates simultaneously with the reflector housing. The beam spread delivered by the luminaire has a bright center and a soft perimeter so that the bright center may be used as accent lighting and the peripheral light may be used for soft general lighting.
Patent CA-2248425-A1 (CA)
Inventor: O'BRYAN DAVID PATRICK
IPC: G01N35/04
Filed: 1998-09-25
Abstract: The puck for a sample tube includes a housing, a spring device and an end cap. The spring device has an annular base portion and angularly spaced spring arms that extend upwardly from the base portion and then bend downwardly toward the base portion. The end cap includes a hub portion around which the spring device is mounted. The cap with the spring device are fixed at one end of the housing and a portion of the spring arms extend into the interior space of the housing. The downwardly directed portion of the spring arm includes a sample tube engaging portion that is substantially parallel with a central axis of the housing. Thus a sample tube inserted in the puck engages the sample tube engaging portions of the spring arms which exert a biasing force against the sample tube. The spring arms provide an optimum restraining force against the sample tube to permit easy insertion and removal of the sample tube from the puck.

Patent CA-2260521-A1 (CA)
Title: Rotatable die holder
Inventor: DLASK JIRI
IPC: E21B19/16
Filed: 1999-01-28
Abstract: A jaw assembly is provided for a power tong or back-up tong to make up and break out a pipe section. The jaw assembly includes a jaw element for transferring torque from the tong to the pipe section, and a means for moving the jaw element into and out of gripping engagement with the pipe section. At least one die holder is rotatably mounted to the jaw element and is adapted to freely twist about a first axis oriented generally parallel to a longitudinal axis of the pipe section when engaged with said jaw element. The rotation of the die holder about the first axis allows the die holder to align itself with the pipe section upon engagement therewith and to provide an independent camming action against the pipe section to at least radially maintain the die holder's grip on the pipe section and avoid slippage therebetween when transferring torque. The jaw assembly may therefore be used on a range of pipe sizes without having to change the jaw.

Title: Valve with inflatable membrane
Inventor: BONNEFOUS JEAN
IPC: F16K1/44
Filed: 1999-04-14
Abstract: A valve comprises a body including a chamber and two superposed closures moving in the chamber and the bottom part of the chamber includes a first seat for one closure and a second seat for the other closure. The closures are each carried by a swing mobile between a position in which the closure bears in sealed fashion on the corresponding seat and a position in which the closure is spaced from the seat. The space between the two closures contains an elastic material membrane closing a chamber into which a compressed air feed discharges. The membrane can therefore be inflated and pressed in sealed fashion onto the top closure to close and seal the inlet of a passage which discharges into a space between the two closures.
