Merle E Carr, William M Doane, Robert E Wing, Edward B Bagley: Starch encapsulation of biologically active agents by a continuous process. The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, Curtis P Ribando, John D Fado, February 2, 1993: US05183690 (58 worldwide citation)

Biologically active agents to be encapsulated are continuously blended with a starchy material and water, subjected to high-shear mechanical action at a temperature above the gelatinization temperature of starch, and continuously recovered as an insolubilized matrix of starch that entraps discontinu ...

William M Doane, Sukumar Maiti, Robert E Wing: Encapsulation by entrapment within matrix of unmodified starch. The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, Curtis P Ribando, John D Fado, March 27, 1990: US04911952 (51 worldwide citation)

Chemical biological agents to be encapsulated are blended into an aqueous dispersion of an unmodified starch comprising about 5% to about 25% by weight amylose. The dispersion, having an initial starch solids content of about 20% by weight, is characterized by completely disrupted starch granules an ...

Charles L Swanson, Robert E Wing, William M Doane: Removal of heavy metal ions from wastewater. The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, Max D Hensley, David G McConnell, March 30, 1976: US03947354 (30 worldwide citation)

Concentrations of undesirable heavy metals in industrial wastewater are reduced to below or very close to the most stringent aqueous discharge limits. This is accomplished by forming an insoluble metal-polyelectrolyte complex which can be easily and economically removed from the effluent.

The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, David G McConnell, Curtis P Ribando, September 27, 1977: US04051316 (24 worldwide citation)

An insoluble alkali metal-magnesium starch-xanthate composition is prepared which is capable of removing most heavy metal ions from aqueous solutions. Concentrations of heavy metal ions contained in several industrial effluents were reduced to below the most stringent aqueous discharge limits.

Warren E Rayford, Robert E Wing: Crosslinked starch halohydrins and their nitrogen-containing substitution products. The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, David G McConnell, Curtis P Ribando, December 2, 1980: US04237271 (2 worldwide citation)

Crosslinked starch is reacted with an epihalohydrin in the presence of a strong acid catalyst to produce the 3-halo-2-hydroxypropyl ether. Substitution of the halogen with nitrogen-containing compounds enables the preparation of novel water-insoluble cationic, anionic, and chelating starch ethers, a ...
