Patent CA-2448951-A1 (CA)
Title: Temporary alarm locate with intermittent warning
Inventor: TANGUAY WILLIAM P
IPC: G08B29/18
Filed: 2003-11-12
Abstract: A method of intermittently disabling the generation of an alarm signal by a plurality of interconnected adverse condition detectors during a temporary alarm locate period such that the adverse condition detector actually detecting the adverse condition can be identified. In an interconnected system of adverse condition detectors, all of the detectors generate an alarm signal when any of the detectors is sensing an adverse condition. When the test switch on any of the detectors not actually sensing the adverse condition is actuated, the alarm signal is inhibited on all of the detectors except the detector actually sensing the adverse condition. The alarm signal is inhibited for a majority of the alarm locate period and allowed to activate for only portions of the alarm locate period.

Inventor: CHEN LONG HSIUNG
IPC: A61B5/153
Filed: 2003-12-09
Abstract: A safety syringe with retractable needle is disclosed. The syringe body contains a hollow needle mounted on a base. An ear on the base extends through a guide slot in the wall of the body. The ear follows the guide slot and allows the needle to extend and protrude from the end of the body or be retracted back into the body after use. A front and rear lock slot hold the needle in an extended or retracted position. Once retracted, the needle tilts to one side, thus easily identifying the syringe as used and preventing the needle from accidentally protruding from the syringe body.      A vial removal knob provides easy removal of the sample vial. A rear cover closes the end of the body to prevent the rear needle tip from protruding from the body. Therefore, a high degree of safety for medical personnel and patients is ensured.

Patent CA-2469392-A1 (CA)
Inventor: BAUGH JOHN L
IPC: E21B43/10
Filed: 2002-12-04
Abstract: A thread for expandable downhole tubular connections is disclosed. It features a locking pattern on the pin and box, which engages upon expansion of the connection. The locking pattern compensates for longitudinal shrinkage away from a torque shoulder, as a result of expansion. A resilient seal can be incorporated into the design with pin to box clearance disappearing around the seal as a result of expansion. Resilient seals can be used in tandem to trap atmospheric pressure between them. The wellbore hydrostatic pressure helps engage the locking feature by pushing the box into the pin, helped by the trapped low pressure between the seals. A thread for expandable downhole tubular connections is disclosed. The thread on at least one of the pin and box is coated, preferably with an anti-galling compound. During expansion the coating crumbles and the particles in between the threads keep the joint from becoming undone despite longitudinal shrinkage from the expansion or any tendency o f the swage to impart a rotational motion on one part of the joint during the expansion process.

Title: Swollen starch-latex compositions for use in papermaking
Inventor: LALEG MAKHLOUF
IPC: C08B30/12
Filed: 2003-04-07
Abstract: A filler treatment comprising the preparation of swollen starch-latex compositions, prepared in the presence or absence of co-additives, and the addition of the said composition to a filler suspension, has been developed.  Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch-latex compositions can be prepared in a batch or jet cooker, or by mixing (7) with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch-latex composition is then rapidly mixed with the filler slurry (5), preferably in a static mixer (6), and added to the papermaking furnish (1) at a point prior to the headbox (3) of the paper machine. The starch-latex composition can be used with wood-free or wood-containing furnishes. The treated filler is easily retained in the web during papermaking, improves drainage, and gives sheets having good formation. Sheets made with the treated fillers have higher bonding and tensile strengths than sheets produced using filler treated with either swollen starch alone or latex alone.
