Patent CA-2419643-A1 (CA)
Inventor: BUTTERFIELD CHARLES A JR
IPC: E21B33/16
Filed: 2003-02-21
Abstract: A running tool for wiper plugs used in cementing well casings into a wellbore. The running tool and setting balls or darts used to launch the plugs are retrievable following deployment of the plugs. Flapper valve assemblies on the wiper plugs are activated after the plugs are displaced from t;he running tool to eliminate the requirement to maintain a setting ball or dart in engagement with the wiper plug as the assembly is pumped down the well casing. Because of being retrievable, the mandrel, setting sleeves and setting ball or dart may be constructed of any desirable high-strength material without regard to the need to drill up the material following completion of the cementing job. The use of high-strength steel permits large flow passages to be employed in the cementing plugs by eliminating the need for large volumes of drillable metals in tile plugs. The running tool protects the flapper valve seal surfaces from circulating fluids prior to deployment of the plugs from the tool.

Inventor: SMITH JOHN BROOKS
IPC: E04B1/76
Filed: 2003-03-13
Abstract: A pre-cut resilient fibrous insulation blanket includes a plurality of longitudinally extending blanket sections that are formed in the blanket by a plurality of laterally spaced apart cut and separable connector arrangements that hold the insulation blanket together for handling but enable the insulation blanket to be separated at any of the cut and separable connector arrangements to form a reduced width resilient fibrous insulation blanket. The number and widths of the blanket sections together with the lateral compressibility and resilience of the insulation blanket or a reduced width insulation blanket formed from the insulation blanket enable the insulation of essentially any width framework cavity up to the width of the insulation blanket with no more than one separation of the insulation blanket.

Title: Rac cooling
Inventor: CHEHOURI RAFIC
IPC: H01F27/12
Filed: 2003-07-07
Abstract: Method of cooling oil immersed transformer or an electrical machine by heat transfer to a liquefied gas, e.g. Freon. A first heat exchanger transfers heat from oil to liquefied gas, which circulates in a closed heat pump circuit with an evaporating cycle. Finally heat is removed by airflow. This done by either using external or remotely cooler unit containing heat exchanger in communication with conventional refrigeration unit on trailer or any fixed or movable applicable method to locate near Transformer, or by directly locating the heat exchanger and/or pre-engineered evaporating coil within the transformer housing connected to outside refrigeration unit. My new Transformer Oil cooler unit can be applied to existing transformers or can be adopted in new design and manufacturing of electrical Transformers, which can have better temperature control, and better cooling for the hot spot area in Transformers. This is a practical and cost effective system to cool electrical Transformers particularly under extreme conditions in which it will boost the transformers output and enhanced its efficiency. My system has not been previously available.      My invention is liquid (Oil) -to-Gas cooling method and not to be confused with current Liquid-to-liquid or any Gas-to-Gas cooling practice.

Title: Method for cutting extruded profile sections
Inventor: BIRKENSTOCK ALF
IPC: B21C23/12
Filed: 2003-03-05
Abstract: The invention relates to a method for cutting hollow-shaped extruded profile sections in a press flow, wherein the extruded profile section is bent upon exit from the press either simultaneously with or directly after the forming extrusion process by means of a force acting thereon in a transversal manner in relation to the direction of the extruding press, and a force component acts as a traction of pressure force during the forming extrusion process on the cross-sectional area of the hollow-profile walls thus arising. The bent extruded profile section is cut in the press flow by the mechanical action of a saw, whereby force exerted on the extruded profile section during cutting is compensated by a supporting device arranged adjacent to the extruded profile section, so that deformation of the bent extruded profile section is prevented. The extruded profile section is made from an aluminium or magnesium alloy and has a temperature of 200 ~C - 600 ~C during cutting.
