Patent CA-2179601-A1 (CA)
Inventor: EDWARDS JEFFREY CHARLES
IPC: F16K17/04
Filed: 1994-12-21
Abstract: A safety valve for use with horizontal subsea trees as described which uses a two-part (10, 12) safety valve system.  The first part (10) containing a valve mechanism (16, 18, 22, 26) remains in the wellhead and is normally biased to a closed position.  The valve mechanism (16, 18, 22, 26) remains in the wellhead at all times during production and can  be actuated to an open position by latching in a second part (12) which contains control cables (58) and a moveable valve actuator (62, 70, 40, 26) operable from the surface during workover to actuate the valve (18) in the wellhead portion (10) open.  This provides for greater safety during the workover phase in comparison to a wire set plug and also allows safer re-entry to the well.
Patent CA-2182941-A1 (CA)
Title: Firefighter Protective Turnout Pant
Inventor: BARBEAU CLAUDE
IPC: A62B17/00
Filed: 1996-08-08
Abstract: The firefighter's turnout pants according to the invention are designed so that each pant leg comprises a front panel and a back panel above the knee region, the panels being joined by an outseam and an inseam, and cylindrical panels below the knee region, the cylindrical panels being each joined by only an outseam and connected via a circumferential seam at the knee to the two-panels above the knee. The absence of an inseam below the knee of the firefighter's pants eliminates a chronic problem of abrasion of the threads used in that portion of the inseam and subsequent failure of the inseam. The absence below the knee of an inseam with the potential for failure reduces the maintenance and repair of the firefighter pants, reduces the risk of burn injury resulting from a breach in the protective envelope of the firefighter's pants, and reduces the incidence of reflective trim becoming coincidentally detached from the pants.

Title: Method and apparatus for purification of ventilating air
Inventor: NOREEN LARS
IPC: B01D53/81
Filed: 1995-06-21
Abstract: A method of cleaning ventilation air that is contaminated with at least two organic solvents, wherein the ventilation air is caused to pass through fluidized beds that contain material capable of adsorbing the solvents and thereafter capable of releasing the organic substances present in the solvents by desorption. The ventilation air is caused to pass first through at least one first fluidized bed (2, 3) that contains an adsorbent material particularly suited for adsorption of one of the organic substances, and is then passed through at least one second fluidized bed (4, 5) that contains an adsorbent material particularly suited for adsorption of the other of said organic substances. The adsorbents are then tapped off separately from the first and the second beds for regeneration of the adsorbents by desorption of the organic substances, whereafter the absorbents are returned to their respective beds. The invention also relates to an arrangement for use when carrying out the method.

Title: Swept range gate radar system for detection of nearby objects
Inventor: HEGER CHARLES E
IPC: G01S7/03
Filed: 1995-08-23
Abstract: A cost-effective ultrawide band radar system (32) capable of locating nearby buried objects such as reinforcing steel rods, pipes and other objects buried in concrete, soil, behind walls or in the air. A sequence of ultrawide band radar pulses are emitted without a carrier and the system (32) detects reflected pulse energy caused by the transmitted pulse whenever encountering a change in the medium, i.e. an air to metal change or concrete to metal change.  This reflected energy is detected and visually displayed. A range gate delay is continuously varied, thus changing the distance from the unit to where the reflected energy would be potentially detected from the target. By continuously sweeping the "depth" of the scan, the operator need only move the unit in two dimensions across the surface to detect objects buried or hidden at varying depths interior to or behind the surface.

Abstract: A golf ball retrieving device designed for the purpose of retrieving golf balls from golf course water hazards. The device is comprised of a cylindrical retrieval cup to which is attached a string or cord that bisects the opening at one end of the cup and attaches to a sliding apparatus that tightens the cord, when the device is lifted up, capturing the golf ball within the cylindrical cup. The opposing end of the cylindrical retrieval cup incorporates a "scoop" that assists the operator in retrieving golf balls from water traps with very soft floors. The sliding apparatus is held and allowed to slide, within the retaining forks on the cylindrical retrieval cup, by means of a tongue and groove configuration and is attached to the telescopic handle.

IPC: A61L11/00
Filed: 1996-02-28
Abstract: A collection vessel (20) is connected with inlet fitting assemblies (12, 14) for receiving waste fluids. The collection vessel is connected by a valve (74) with a drain (70) for selectively draining collected fluids. A fluid inlet (84) that is connected with an exterior water source supplies water through interconnecting tubing to rinse waste residue from the collection vessel. The water flows through a housing member (200) that surrounds a tubular member (214) of the inlet assembly. The housing member is spaced by spacers (216) from the bottom surface (220) of a well (210) surrounding the tubular member such that trapped water is drained through a drain outlet (222). Powdered reagent (170a, 170b) is received in a cup (26) that is carried by a drawer (166) to a position above a fluid mixing reservoir (124). A mechanical actuator (174) lifts a mechanical assembly (176) which defines the reservoir, forcing a cutting blade (180) to pierce and cut open the cup. A pump (128) recirculates the water through the reservoir (124) to make a disinfectant fluid concentrate which is supplied to a venturi (120) to be selectively entrained in the rinse water.
