| 20090139905 | ENDLESS CABLE SYSTEM AND ASSOCIATED METHODS - A separation apparatus can include at least one endless cable. The cable can be wrapped around at least two revolvable cylindrical members a plurality of times. The wraps can form gaps between adjacent windings, which, along with the endless cable, can be used to facilitate separations processing. Additionally, the separation apparatus can optionally include a repositioning guide for each multiple wrap endless cable that can guide the endless cable in an endless route and prevent the cable from rolling off or falling off of the cylindrical members. Separation can be accomplished by oleophilic adherence to the cable, electrostatic adherence to the cable, and/or physical retention on the cable. This endless cable system can be particularly useful for separation of oil sand slurries, mass transfer operations, and physical separations. | 06-04-2009 |
| 20090294384 | REMOVAL OF BITUMEN FROM SLURRY USING A SCAVENGING GAS - A separating apparatus can be used for separating components of a fluid. The apparatus can include a substantially open cylindrical vessel and a helical confined conduit connected upstream of the cylindrical vessel. The open vessel can include an open vessel inlet configured to introduce a fluid tangentially into the open vessel. The helical confined conduit can be connected to the open vessel at the open vessel inlet. A series of gas nozzles can be used to introduce gas bubbles into the helical confined path and/or the open vessel which draw bitumen from an outer flow region to an inner flow region of the slurry. An overflow outlet and underflow outlet can be operatively attached to the open vessel for removal of the separated fluid components. Although a number of fluids can be effectively treated, de-sanding of bitumen slurries from oil sands can be readily achieved. | 12-03-2009 |

| 20090120850 | HYDROCYCLONE AND ASSOCIATED METHODS - A hydrocyclone can be used for separating components of a fluid. The hydrocyclone can include a substantially open cylindrical vessel and a helical confined path connected upstream of the cylindrical vessel. The open vessel can include an open vessel inlet configured to introduce a fluid tangentially into the open vessel. The helical confined path can be connected to the open vessel at the open vessel inlet. One or more wash inlets can be used to introduce a wash fluid into the helical confined path and/or the open vessel. An overflow outlet and underflow outlet can be operatively attached to the open vessel for removal of the separated fluid components. Although a number of fluids can be effectively treated, de-sanding of bitumen slurries from oil sands can be readily achieved. | 05-14-2009 |
| 20090122637 | SINUSOIDAL MIXING AND SHEARING APPARATUS AND ASSOCIATED METHODS - An elongated conduit can be used for mixing and/or shearing a fluid. The elongated conduit can be configured as a repeating sinusoidal wave in a two-dimensional plane that is sufficient to restrict a line of sight down the length of the conduit. A method for mixing or shearing a fluid can include injecting the fluid at a high velocity into an end of a length of such a baffle-less conduit. Although a number of fluids can be effectively treated, disengagement of bitumen from the solids of oil sands ore and further treatment of bitumen products from other oil sands separation processes can be readily achieved. | 05-14-2009 |
| 20090139906 | ISOELECTRIC SEPARATION OF OIL SANDS - A process and system for substantially isoelectric separation of an oil sand slurry is disclosed and described. The process can include mining oil sand, crushing the oil sands, forming a slurry of the oil sands, and transporting the oil sands slurry to a sinusoidal pipe. The sinusoidal pipe acts to digest the slurry from which bitumen can be separated using a hydrocyclone. Overflow from the hydrocyclone can be further treated using a revolving oleophilic device from which bitumen is recovered. Various optional further treatments can be used to dewater and/or further treat the bitumen and other process streams. The use of caustic soda, long-term tailing ponds, and froth flotation can be avoided resulting in an effective production of oil using less water than currently conventional processes. | 06-04-2009 |

| 20100058698 | DECORATIVE PLASTIC BATTEN SHUTTER - A decorative shutter assembly including a plurality of main slats arranged in side-by-side relation, end pieces positioned at each end of the main slats and each including laterally spaced tongues spaced and sized to fit in their respective open ends of the main slats at a respective end of the main slats, and cross slat structures positioned in overlying relationship to seams formed between inboard ends of the end pieces and the respective ends of the main slats. The cross slat structures are removably secured to the end pieces and to the main slats so that, following delivery of the shutter assembly to a building site, the cross slat structures may be removed, the end pieces and main slats may be secured to a building surface utilizing fastener members, and the cross slats may be repositioned over the fastener members to conceal the fastener members. | 03-11-2010 |
