Patent CA-2677867-A1 (CA)
Title: Temperature triggered actuator
Inventor: CHEN KUO CHIANG
IPC: E21B43/24
Filed: 2009-03-12
Abstract: An actuator is disclosed which operates on the principle of the variable magnetic properties of materials with respect to temperature. As temperature is raised past Curie temperature, magnetic permeability of certain materials drops significantly to a value close to free space permeability. However, depending on the material selection, magnetic permeability may be significantly higher below Curie temperature. This principle is used to cause magnetic attractive force to move an actuator at one temperature, while permitting a return spring force to move the actuator at another temperature by changing the pathway traversed by most magnetic lines of flux from a magnetic source. The actuator may be employed to provide a temperature activated electrical switch or fluid valve. The temperature activated valves are suited to use in high temperature environments, such as SAGD wells.

Patent CA-2696549-A1 (CA)
Inventor: MCCUTCHEN WILMOT H
IPC: B01D61/02
Filed: 2007-10-19
Abstract: Simultaneous source-sink flow, or radial counterflow, is driven by a centrifugal pump disposed within a casing.  Radially outward source flow of brine goes into a shrouding tank and concentrates while a radially inward sink flow of fresh water flows back over the pump to axial extraction.  An axial pump drives sink flow and axial extraction. Convergent sink flow passes under an inductor to an axial exhaust port.  Induced viscosity and inductive repulsion hinder the passage of brine in sink flow, so only fresh water can reach the axial exhaust port. Crystallization of scale-forming salts is aided by Joule heating from the inductor.  Solvent and gases are continuously axially extracted in sink flow, favoring crystallization.  Sodium chloride is cooled and crystallized in the shrouding tank. Brine comprising other salts flows out of the tank to treatment by suitable means. Thus brine is separated into fresh water, crystallized salt, and concentrated brine. Oil also is separated from brine.  Metal recovery is another application, using the teacup effect, inductive repulsion, and grooved runners on the centrifugal pump to separate metals from light solids and water. Tiny centrifugal separation effects of innumerable turbulent eddy vortices are integrated by the forcing regime of the centrifugal pump and the axial pump. A coherent network of organized low pressure gradients along capillary and arterial vortices gives bulk porosity so that sink flow can go through source flow. In an embodiment comprising counter-rotating impellers in the centrifugal pump, radial vortices provide arterial conduits for sink flow of fresh water and gases to axial extraction.
