Title: Method of removal of hydrocarbons from soils using solids loaded polymer foam
Inventor: RYERSON JAMES GEORGE
IPC: B01J20/16
Filed: 2001-11-05
Granted: 2005-06-28
Abstract: A method of removal of hydrocarbons from soils using solids-loaded polymer foam. A first step involves providing a solids-loaded polymer foam consisting of an open-celled polymer foam matrix with zeolite dispersed and bound throughout the foam matrix. A second step involves mixing soils containing hydrocarbons, solids-loaded polymer and water. It has been found that hydrocarbons are adsorbed by the solids loaded polymer foam. The order of mixing can be altered to suit particular applications. A recovery step can be added to recover the hydrocarbons from the solids-loaded polymer foam.

Abstract: The invention relates to a method of hot-repairing the heating flues of a coke--oven battery according to which the completed sections of a heating flue still un-der construction are heated by means of a heated gas. As heated gas the air usually provided for combustion in heating flues during coking operations is used.  This air is guided through the flow paths provided for in the coke-oven battery for combustion air and waste gases as well as through the regenerator, heated as it passes through said paths and then guided through the heating flues to be re-paired.    The completed section of the heating flue is separated from the part still to be constructed by an air-reversion device.
Patent CA-2369860-C (CA)

Abstract: Apparatus and methods are disclosed for actively controlling the flow of hydrocarbon fluids from a producing formation at the downhole sand screen.   A preferred embodiment of the invention provides a fluid flow annulus within the production tube inside of the screen in a first flow control configuration, fluid passing through the screen is required to flow along the annulus to find a flow aperture into an interior flow bore. A static flow control device within the annulus between the sand screen and a first flow aperture dissipates flow energy by forcing the flow through a restricted area that helically winds about the flow annulus. Dissipation of the flow energy increases the pressure reduction from the screen into the production bore and reduces the flow velocity. In a second flow control configuration, flow control structure within the flow annulus obstructs all flow along the annulus. A third flow control configuration removes all flow restrictions within the flow annulus.

Abstract: The retrieval tool includes a cylindrical member having a body, an inner passage, a guide cylinder and an engaging member. The engaging member may slide within the cylindrical member in order to engage a whipstock against an inner surface of the guide cylinder, facilitating removal of the whipstock from a borehole.  A actuating member, piston, retainer and swivel sub may be used to connect the engaging member to the retrieval tool and enhance the mobility of the engaging member within the cylindrical member. A spring may also facilitate locking engagement of the engaging member and whipstock. Contact between the retrieval tool and the whipstock may lead to an increase of pressure within the inner passage, such pressure increasing the engagement between the engaging member and whipstock.

Abstract: The invention is based on the problem of designing an endless sealing ring for the end wall seal of rotary kilns so that it guarantees a high degree of sealing effectiveness with simpler assembly. The most desired features are small tolerances for cross section and diameter. Rotary-kiln end-wall seals according to the invention should exhibit very low wear and tear if possible and have a service life that corresponds to the maintenance intervals of the rotary kiln as much as possible. This problem is solved for an annular, closed seal for the end seal of a rotary kiln between the rotating tube and the stationary end walls, wherein a core ring has a polygonal, preferably rectangular, cross section with a joint protected from tensile loads and the core ring is surrounded by an endless braid to form the desired final cross section, such that the joint of the core ring is fixed and protected from tension, preferably by tension-relieving threads or fibers extending in the ring circumferential direction and anchored on both sides of the joint.

A second portion of the beam impinging upon the cells in the flow cell is scattered at a much lower angle than 90~ and is collected on two distinct photo detectors, that represent 'forward scatter low' which has an angle of from about 1~ to about 3~ and 'forward scatter high' which has an angle of from about 9~ to about 12~ from the original beam from laser input. A third photo detector is placed between the two forward scatter detectors and measures axial light loss.
