Patent CA-2464723-A1 (CA)
Title: Intermittent aerosol dispensing valve
Inventor: HOUSER DAVID J
IPC: B05B9/04
Filed: 2002-10-30
Abstract: A valve assembly (32) is provided that automatically dispenses aerosol content from a can (22) at predetermined intervals. A diaphragm (70) at least partially defines an accumulation chamber (71) that receives aerosol content from the can (22) during an accumulation phase. Once the internal pressure of the accumulation chamber (71) reaches a predetermined threshold, the diaphragm (70) flexes to initiate a spray phase, during which the aerosol content is delivered from the accumulation chamber (71) to the ambient environment. A  rotatable pawl (78) provides resistive pressure and control of diaphragm movement.

Title: Continuously variable transmission
Inventor: CHONAN MITSUGI
IPC: F16H57/035
Filed: 2004-04-15
Abstract: Cooling efficiency of cooling air is enhanced and durability of a continuously variable transmission is improved. The continuously variable transmission to be mounted on a vehicle has a transmission case. A primary pulley driven by an engine and a primary pulley linked to drive wheels are rotatably accommodated in the transmission case. A V-belt is provided to extend for winging between the primary pulley and the secondary pulley, and the rotation of the primary pulley is continuously changed and transmitted to the secondary pulley. Fan blades are formed in the primary pulley, and a scroll surface is formed in transmission case from an intake region of the cooling air toward a discharge region thereof so as to gradually away from top faces of the fan blades in a radial-outer direction. Thereby, blowing efficiency of the cooling air can be enhanced and an interior of the transmission case can be sufficiently cooled, whereby the durability of the V-belt can be enhanced.

Title: Flare stack safety system and method of use
Inventor: PICKLES IAN
IPC: F23D14/72
Filed: 2004-04-29
Abstract: In the context of an oil or gas well site flare system, a safety system is provided so that in the event of a flammable gas release at the well, the safety system can be activated to extinguish the sources of ignition. Activation of the safety system does not prevent the continued venting or exiting of flare gases from the flare stack.

Abstract: A roofing component adhering assembly includes a bitumen layer having first and second major surfaces and at least a first release sheet substantially coextensive with the first major surface of the bitumen layer. The first release sheet is separable from the first major surface of the bitumen layer so that the bitumen layer of the roofing component adhering assembly can be used to adhere together overlapping surfaces, such as end and/or lateral edge portions, of first and second roofing components. The roofing component adhering assembly is especially well suited for adhering surfaces together where one of the surfaces is a granule surface, such as an end edge portion of a cap sheet. Preferably, styrene-butadiene-styrene modified bitumen is used to form the bitumen layer.
Patent CA-2469778-A1 (CA)
Inventor: COUTURE PIERRE
IPC: H02J3/24
Filed: 2004-06-04
Abstract: A new class of devices is proposed for flexible AC transmission systems (FACTS) for HV power lines with bundled conductors. These new FACTS devices are based on Switching Modules (SMs), which are mounted on insulated portions of the transmission towers in close proximity to the line conductors. These SMs are composed of electro-mechanical and power electronic switches and could be coupled to some other passive components. Such SMs can be used for connecting/disconnecting one or more sub-conductors of a phase bundle of the power' line at numerous line segments in the network. Power flow is managed ire the line segment by changing the series impedance of the line segment with the SM.      Furthermore, the SM could also be used for the extraction/injection of active/reactive power from a segment of the HV line. Power flow management in an electrical power transmission network could be achieved by using serial SMs distributed throughout the transmission lines of the network. The system and method could eventually be used for modifying, in a steady state or dynamic manner, the power flow through an electric power line. The passive components coupled with the SM improve the range of impedance modulation. A whole range of applications of the SMs could be developed.

Title: Blind fastener with a blind side head having a clamp support and lock section
Inventor: BUSBY DONALD C
IPC: F16B19/10
Filed: 2002-12-04
Abstract: A two piece blind fastener (10) for securing a plurality of workpieces (20, 22) including a hollow sleeve (12) having an enlarged sleeve head (26) at one end and a pin (14) having an enlarged shear ring (46) at the end opposite the sleeve head followed by an elongated retention portion (48) of reduced diameter. The shear ring is adapted to engage and move inside the sleeve to form a tuliped shaped blind head in response to a relative axial force applied between the pin and sleeve and to shear off proximate to the inner or blind sheet line (64) of the workpieces. The retention portion is then moved with the pin shank (40) into the shear ring and with the shear ring finally located at a position on the retention portion depending upon the overall thickness of the workpieces. This provides a clamp and lock section between the pin and sleeve at the inner or blind side of the workpieces. The pin and sleeve have a lock structure actuated after final formation of the clamp and lock section to provide a lock between the pin and sleeve.
