Patent CA-2163132-A1 (CA)
Title: High-pressure discharge lamp and process for producing it
Inventor: WITTIG CHRISTIAN
IPC: H01J9/26
Filed: 1994-05-25
Abstract: The invention relates to a high-pressure discharge lamp with an outer bulb surrounding the discharge vessel, and to a process for producing a high-pressure discharge lamp.  The outer bulb (1) comprises a glass that has a low viscosity and in particular a lower softening temperature than the quartz glass of the discharge vessel (2), and is melted directly onto the ends (5a, 5b) of the discharge vessel (2), which is sealed on both ends.  As the glass for the outer bulb, a quartz glass doped with viscosity-lowering additives, in particular alkaline-earth metal borates, is used, while the discharge vessel comprises undoped quartz glass.  In addition, the quartz glass of the outer bulb is preferably doped with rare earth metal additives that absorb UV radiation.  To avoid projection errors, the axis of symmetry of the substantially rotationally symmetrical outer bulb (1) is shifted parallel relative to the path connecting the electrode heads by an amount that, for a horizontal lamp operating position, is defined by the convection-dictated curvature of the discharge arc.

Patent CA-2191262-A1 (CA)
Title: Marsh case
Inventor: CHEEMA TARSEM S
IPC: E21B47/107
Filed: 1996-11-26
Abstract: An improved marsh case is disclosed.  The marsh case contains and protects a geophone, which is inserted into the earth in the course of oil exploration.  The marsh case provides an cap having an upper opening through which wires pass to the geophone and a lower internally threaded opening that attaches to the body of the case.          The  body of  the  case  provides  an  upper  externally threaded opening which attaches to the cap, and a lower internally  threaded  conical  surface  which  allows  a threaded cylindrical surface of a spike to be attached.          The threads of the body are slightly tapered, thereby relieving some of the stress that would otherwise be applied to the threads. The rim of the upper external threaded opening of the body and an internal annular shoulder in the cap compress an O-ring, thereby making a water-tight seal.  A quad ring seal is supported by a second internal shoulder in the cap, in a manner that firmly engages the geophone, allowing for compression of the quad ring seal in the event that the marsh case contracts due to temperature,  thereby protecting the geophone from compression.

Patent CA-2205768-A1 (CA)
Inventor: MICHAEL ROBERT J
IPC: B25D17/04
Filed: 1997-05-21
Abstract: A vibration-reduced impact tool is disclosed wherein an elastomeric vibration isolator is fixedly attached within the tool housing and functions to absorb the vibration typically transmitted from the handle to the operator. The isolator is mounted between the cylinder assembly and the handle. As the tool is operated, a piston within the cylinder assembly is driven forward where it impacts with a tool accessory. The impact causes the piston and cylinder assembly to slide rearward in the tool housing, toward the handle. The elastomeric isolator absorbs the rearward movement of the cylinder assembly and thereby eliminates much of the vibration normally transmitted from the cylinder assembly to the handle and in turn, to the operator.
Patent CA-2206065-A1 (CA)
Inventor: GRIMARD JEAN PIERRE
IPC: A61M5/315
Filed: 1997-05-26
Abstract: A stopper assembly having by-pass features for use in a multi-chamber syringe barrel. The stopper assembly includes a sequential stopper body responsive to fluid forces for enabling the sequential delivery of disparate contents, such as disparate fluids, separately held in the syringe barrel. The sequential stopper body has a generally cylindrical sidewall with a distal end, a proximal end and a longitudinal axis therethrough. The stopper assembly also includes a generally cylindrical flow channelizer mounted to the distal end of the sequential stopper body. The flow channelizer enables the reconstitution of dry medicament held in the syringe barrel distally of the flow channelizer. The flow channelizer features opposed proximal and distal ends and a generally cylindrical outer surface therebetween. At least one fluid flow channel extends between the proximal and distal ends of a flow channelizer. A distally directed, conically-shaped projection is located at the distal end of the flow channelizer to prevent the accumulation of dead space between the channelizer and the internal shoulder located at the distal end of the syringe barrel. The stopper assembly may be employed in a multi-chambered syringe barrel featuring a by-pass channel to permit fluids to pass distally of the stopper assembly. The multi-barreled syringe barrel can be separated into disparate chambers by one or more by-pass stoppers so as to contain disparate components intended for sequential delivery by the stopper assembly.
Patent CA-2207760-A1 (CA)
Title: Anti alpha-galactosyl screening technique
Inventor: POULETTY PHILIPPE
IPC: C07K1/04
Filed: 1996-09-27
Abstract: Compounds and libraries are labeled with a galactosyl epitope and then screened in accordance with an assay involving cells having a characteristic of interest. Conveniently, the screening may embody target cells, where the compounds are brought in contact with the cells. Each of the compounds carries with it the information of its identity or method of synthesis. After washing away non-specifically bound compounds, blood may be applied to the cells, whereby antibody binding to the galactosyl epitope initiates the complement cascade. Plaques are identified and the compound associated with the plaque identified. The formation of the plaque demonstrates that the compound has specific affinity for the target cell, binding of the compound to the cell does not interfere with binding of the antibody, and that the complex is capable of cytotoxic activity by means of the complement cascade.
