David Farrar, John G Langley, Adrian S Allen: Water soluble polymeric compositions. Allied Colloids, Ostrolenk Faber Gerb & Soffen, May 30, 1989: US04835206 (101 worldwide citation)

A homogenous blend is formed of different water soluble polymer types, for instance of particular addition and condensation polymers, by forming one of the polymers from its monomeric starting material by polymerisation in a solution of the other polyer. The resultant solution has a concentration of ...

John G Langley, Kenneth C Symes, Kishor K Mistry, Peter Chamberlain: Particulate composition comprising a core of matrix polymer with active ingredient distributed therein. Allied Colloids, Ostrolenk Faber Gerb & Soffen, October 24, 1995: US05460817 (73 worldwide citation)

A particulate composition comprises particles having a substantially anhydrous core comprising an active ingredient. Generally the core comprises a matrix polymer with the active ingredient distributed throughout this. Generally there is an outer protection shell of polymer, generally formed by coac ...

John G Langley, Edward Litchfield: Production of newprint, kraft or fluting medium. Allied Colloids, Lawrence Rosen, December 15, 1981: US04305781 (43 worldwide citation)

The drainage and retention properties of an aqueous cellulosic suspension substantially free of filler and which is being used for the production of paper or paper board are improved by including a water soluble high molecular weight substantially non-ionic polymer and a bentonite-type clay.

Thomas A Cauley, John G Langley, Adrian Nixon: Production of paper. Allied Colloids, Sughrue Mion Zinn Macpeak & Seas, May 7, 1996: US05514249 (21 worldwide citation)

Paper is made by adding nonionic or anionic polymeric retention aid to a suspension that contains a high electrolyte content, shearing the flocculated suspension, aggregating the sheared suspension by adding anionic particulate material (especially bentonite), and draining the suspension.

This invention relates to the encapsulation of active ingredient within polymeric material so as to protect the active ingredient from the ambient environment, for instance atmospheric moisture when the product is exposed to the air, or the liquid phase of a liquid detergent when the product is inco ...

Jean Cluyse, Philip Ford, John G Langley, Peter Lowry: Clay compositions and their use in paper making. Allied Colloids, Ostrolenk Faber Gerb & Soffen, June 29, 1993: US05223098 (12 worldwide citation)

Bentonite swelling clay is provided to a paper making mill as a fluid concentrate containing more than 15% bentonite wherein swelling of the bentonite is prevented by inorganic electrolyte in the concentrate, and the bentonite swells upon dilution either before addition of the cellulosic suspension ...

Anthony P Allen, Sten Forsmo, John G Langley: Iron ore pelletization. Allied Colloids, Ostrolenk Faber Gerb & Soffen, August 4, 1987: US04684549 (11 worldwide citation)

Finely particulate iron ore is pelletized using finely particulate, free flowing, anionic water soluble synthetic polymer having intrinsic viscosity of from 3 to 16 as binder.

Peter Chamberlain, John G Langley: Particulate materials, their production and use. Allied Colloids, Ostrolenk Faber Gerb & Soffen, March 16, 1993: US05194263 (9 worldwide citation)

Agrochemical and other particulate compositions are formed by coacervation. The coacervate is preferably formed from two water soluble coacervating polymers and stabilizes the particles against agglomeration. The coacervate is preferably formed from a relatively low molecular weight cationic polymer ...

Peter Flesher, John G Langley: Process for dissolving polymeric material. Allied Colloids, August 27, 1985: US04537513 (6 worldwide citation)

A dispersion of polymeric particles in a non-aqueous liquid is mixed with water with sufficient agitation to initiate substantial dissolution of the particles into water and is substantially homogeneously dispersed into the water substantially immediately, for instance in less than 50 milliseconds f ...

Anthony P Allen, Sten Forsmo, John G Langley: Ore pelletization. Allied Colloids, Ostrolenk Faber Gerb & Soffen, March 1, 1988: US04728537 (6 worldwide citation)

Finely divided mineral ore is pelletized using a soluble synthetic polymer. Preferably the polymer is in the form of beads made by reverse phase polymerization and all having a size of below 300 .mu.m. When the ore gives a pH in water of below 8 the soluble polymer is preferably cationic.
