Appl. No.:

09/356271

Charles A. Arnold - Englewood CO

Assignee:

Soil Enhancement Technologies LLC - Centennial CO

International Classification:

C08L 3900

US Classification:

71 27, 71 641, 71903, 428402, 524401, 524423, 524428, 524555, 526310

Abstract:

A method of producing an aqueous solution of water-soluble polyacrylamide (PAM) with a concentration of at least about 5 grams per liter includes the steps of providing a monovalent or divalent cation salt solution, and preferably a calcium salt solution, and adding water-soluble PAM particles to the salt solution such that the PAM particles are essentially all dissolved within about 10 seconds. The PAM particles are characterized by a particle size that is about -100 mesh and consisting essentially of molecules having a molecular weigtht of at least about 15 million a. u. Preferably, the small PAM particles are produced by a mill that produces bulk quantities of small dry, flowable PAM particles from larger commercial grade particles. Small PAM particles produced in such a mill are essentially all soluble in plain water within about 10 seconds. After solution, the polymer concentrate can be diluted with water to make stock solutions of the polymer for some purposes.

International Classification:

US Classification:

241 1, 241 2

Abstract:

A method of liberating intracellular matter from biological material having cells with cell walls includes subjecting the biological material to rapid pressure increases and decreases, and exceeding the elastic limit of the cell walls with the pressure increases and decreases, thereby opening the cell walls and liberating the intracellular material from the cells. This produces a heterogenous mixture of cell wall fragments and the intracellular material. Where the biological material includes pieces of plant animal or fungal material, the method can further include separating the cells of the pieces from each other with the pressure increases and decreases when the elastic limit of intercellular bonds are exceeded. Water and volatiles in the biological material is liberated and vaporized, producing a substantially dry mixture having a lower water content than the original material.

International Classification:

B02C 1912

US Classification:

241 1

Abstract:

The invention provides methods of disintegrating or reducing the particle size of elemental materials, such as various forms of carbon, and organic crystals that contain minerals and that do not contain minerals. The method include the steps of entraining the material in a gas flow through an inlet of a housing, subjecting the flowing material to a plurality of alternating pressure increases and decreases within the housing, disintegrating the flowing material with the pressure increases and decreases, thereby reducing the mean particle size of the material, and discharging the disintegrated material though an outlet of the housing.

US Classification:

Abstract:

A stable aqueous suspension of water-soluble polyacrylamide particles is in a saturated solution of an ammonium salt. The polyacrylamide particles are characterized by a particle size of about −150 mesh, and preferably −270 mesh, with −400 mesh most preferred. The suspension is at least about 2. 5% by weight polyacrylamide. When the ammonium salt is ammonium sulfate, PAM concentrations as high as about 15% by weight can be achieved while still being easily flowable. The suspension is made by stirring the small particle PAM into the saturated ammonium salt solution. The PAM can be quickly dissolved to form a less concentrated PAM solution by adding the suspension to water or to a dilute solution, which can include calcium salts or other soil enhancers.

International Classification:

US Classification:

705035000, 705040000

Abstract:

A method for financing real estate purchases using a shared equity model is disclosed. In the disclosed method, the land portion of the real estate is financed using a land lease agreement, while the improvements to the land (e.g., a house) are purchased under a typical mortgage scenario. The land lease agreement provides for a required minimum annual return on investment to the land equity investor over a predetermined term. The borrower must pay an additional required minimum monthly payment, which may be made to the lender to pay down the mortgage, in addition to the payment required under the mortgage such that the additional required minimum monthly payment is sufficient to meet the required minimum annual return specified in the land lease agreement. Finally, the borrower may defer lease payments to the equity investor, and pay them at some date in the future.

Abstract:

A comminution reactor includes an inlet chamber, one or more processing chambers, and a discharge chamber. Each chamber includes a rotor, and the chambers are separated by split divider plates. The reactor is designed with assemblies comprising portions of the reactor walls and divider plates which rotate open to allow access to the inside of the reactor, including the shaft and attached rotors. The design of the rotors and vortex generators on the reactor walls direct the flow, optimize comminution, and minimize wear on the apparatus.
