Patent CA-2115247-A1 (CA)
Title: Tubing test valve
Inventor: COUTTS GRAEME F
IPC: E21B47/10
Filed: 1992-07-23
Abstract: A tubing test valve (34, 34a) is described for use with a drill string (20) for pressure testing tubulars and downhole equipment, particularly in a cased hole (12) which has a permanent packer (16) fitted. The valve (34) permits self-filling during running-in, but allows pressure testing when stationary in the well (1). The valve (34) also permits multiple entry of the string to, and retrieval from, permanent packers without committing the tool to the locked open position. This is achieved by providing an apertured ball valve (50, 50a) in the tool housing (42, 42a) which can be moved axially and rotated with the bore (70A, 71A) of the housing (42, 42a). The ball valve has side orifices (54, 54a) and a top orifice (52a) which controls flow through the valve (34, 34a). In one embodiment the ball element (50) is suspended by coil spring (64) above the lower valve seat (56) during running-in and is closed for pressure testing by pressuring with fluid from above. In another embodiment the ball element (50a) is biased by a spring (66a) into engagement with the valve seat (56a) when stationary to allow pressure testing during running as the flow of fluid lifts the ball (50a) off its seat (56a) to allow self-filling. In both embodiments the ball element (50, 50a) contains slots (58, 58a) mounted on pins (62, 62a) which allow the ball to be rotated when the tool is in the packer (16) when engaging the valve seat (56, 56a) to break the seal and allow pressure in the bore above (71A) and below (70A) the ball element (50, 50a) to equalise. This allows the tool to be withdrawn from the packer (16).
Patent CA-2116928-A1 (CA)
Title: Radiation curable composition
Inventor: WINKLE MARK R
IPC: C09D135/00
Filed: 1994-03-03
Abstract: ABSTRACT OF THE DISCLOSURE       An aqueous, actinic radiation-curable coating composition containing a latex polymer emulsion and a multifunctional (meth)acrylate is disclosed. The critical aspect of the invention is that the actinic radiation-curable composition does not contain more than 5% by weight of the AOPAte ester of the multifunctional acrylate and 20% by weight of the ether resulting from a Michael addition of a multifunctional acrylate with the hydroxyl group of another multifunctional acrylate. This limitation on the maximum concentration of these components, which are typically the by-products formed in the manufacture of multifunctional (meth)acrylates, results in the improved appearance of the final cured coating.

Title: Fatty acid terminated polyanhydrides
Inventor: DOMB ABRAHAM J
IPC: A61L31/16
Filed: 1992-09-08
Abstract: Fatty acid terminated polyanhydrides suitable for use as controlled release matrices in biodegradable sustained release drug delivery systems and methods for making thereof as described. The polymers are more soluble in organic solvents, and have a lower melting point than the corresponding non-fatty acid terminated polyanhydrides. The fatty acid terminated polyanhydrides are also more hydrophobic than the corresponding polyanhydrides that are not terminated with a fatty acid, and combine the properties of thermodynamic and hydrolytic stability, and easy storage.  The polymers can be produced with a controlled and low molecular weight. The polyanhydrides are useful in a number of applications, including as a matrix in biodegradable drug delivery systems.
Patent CA-2119508-A1 (CA)
Inventor: ARNETT JAIME R
IPC: H04Q1/14
Filed: 1994-03-21
Abstract: In a preferred embodiment, a device which is capable of being mounted in an opening in a panel, and which is adapted to hold a component, comprises two parallel side portions each being made of a plastic material, each side portion including a depending portion at each end thereof. Each of two moveable arms extends between corresponding ends of said side portions and is hingedly connected thereto. Each moveable arm includes two detents projecting from an outer surface of the arm such that when forces are applied to free end portions of the arms to move the free end portions toward each other, the device is capable of being inserted into an opening in a panel until a face of the panel abuts the depending portions of the side portions whereupon the application of forces is discontinued to allow the arms to move outwardly and cause the detents of each arm to snap-lock into engagement with an opposite side of the panel. Furthermore, the present invention additionally includes means which allows the patch panel to adequately support the component in a position which provides ready frontal access to all wiring associated with any single component.

Title: Apparatus and method of ensuring proper machining of a worksheet
Inventor: LINDSTROM MIKKO
IPC: G05B19/4065
Filed: 1992-09-15
Abstract: To ensure that a worksheet (10) ineffectively operated on, the present invention system monitors the life expectancy of a tool (T1) by counting the number of hits (71) the tool has made so that when it is reached, the tool is replaced by a spare tool (T9). Alternatively or in combination therewith, in place of monitoring the life expectancy of the tool, the operational effectiveness of the tool is monitored (62). Thus, anytime that the operational effectiveness of the tool is deemed to fall below a given standard, the tool is replaced by a spare tool. The replacing of the tool by a spare, and the subsequent replacement of the spare tool by yet another spare can go on ad infinitum. With such a system, severe failures of tools are prevented.

Title: Method and device for treating a parenteral emulsion-containing medicament fluid
Inventor: BORMANN THOMAS J
IPC: B01D39/16
Filed: 1993-04-28
Abstract: Parenteral emulsion-containing medicament fluid is treated by passing the fluid into a filter assembly. The fluid is introduced via the inlet into chamber and the fluid then passes through a fluid filtration element into chamber and passes out of the filter device via outlet. Passing the fluid through the filtration element blocks microorganisms and other undesirable substances from passing therethrough.      Gas which may be present in the fluid and/or the filter assembly may be passed through gas venting elements.

Patent CA-2139913-A1 (CA)
Inventor: POLLARD MARK A
IPC: F16F7/09
Filed: 1995-01-10
Abstract: The training, load supporting component of a product conveyor is connected to a powered, leading component by a shock absorbing tow bar that employs a dampener tube in which a plunger moves against the resistance of a sleeve of resilient material.      The head of the plunger is oversized with respect to a passageway defined by the sleeve and thus is forced to compress and displace the resilient material in order to move relative to the passageway in response to an impact caused by rapid acceleration or deceleration of the conveyor. Compression and displacement of the material occurs at a zone of contact of the head with the material, the head shifting the zone of contact and compressing and displacing the material in response to the impact communicated to the tow bar. A protective sleeve shields an exposed plunger rod from contaminants and enhances the structural integrity of the assembly.

Title: Slide actuated holding clamp
Inventor: STOJKOVIC DRAGAN B
IPC: B60R16/02
Filed: 1994-09-28
Abstract: A slide actuated holding clamp for holding a connector stationary while a push test or pull test is performed on a conductor secured to the connector. The clamp comprises a main body portion (102) having an opening (120) formed therein, a locking member (106) adapted to fit nestably substantially within the opening, and an actuating member (104) adapted to fit nestably within a recessed portion in the locking member. The actuating member (104) is pivotally coupled to an upper end portion of the locking member (106) and the locking member (106) is captively held within the opening in the main body portion by a locking pin. The locking member includes elongated openings (140) which allow the locking member (106) to be urged slidably longitudinally within the main body portion (102) as the actuating member (104) is moved in first and second longitudinal directions. The pivotal coupling of the actuating member and locking member (102) allows the locking member to be urged pivotally into abutting engagement with a connector as the actuating member is moved in a first linear direction. The elongated apertures (140) permit the actuating member (104) to urge the locking member (102) generally linearly in the same direction as the actuating member continues to be moved in the first direction. This causes the locking member (102) to exert a positive clamping force on the connector prior to conducting a push test or pull test.
