Bruce E. Banyai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Water soluble polymers as alcohol replacement in lithographic fountain solutions
    Patent number: 5006168
    Abstract: Isopropyl alcohol is partially or completely replaced in an acid fountain solution for lithographic printing by a hydroxypropylcellulose or similar polymer with a molecular weight below 100,000 where a 30% by weight solution of the polymer has a viscosity below 4000 cps at 25.degree.. Printing quality is improved and scumming is controlled when a hydrogen peroxide degraded hydroxypropylcellulose or hydrophobically modified hydroxyethylcellulose replaces alcohol in a fountain solution.
    Type: Grant

  • Ore pellets containing carboxymethylhydroxyethylcellulose and sodium carbonate
    Patent number: 4948430
    Abstract: A binder for agglomerating an ore in the presence of water, contains 10% to 90% of a water-soluble sodium carboxymethylhydroxyethylcellulose and 10% to 90% of sodium carbonate. A process comprises mixing a binder composition containing cellulose and sodium carbonate, water, and the ore, agglomerating the mixture into wet balls, drying the wet balls, and heating the resultant dry balls at a temperature of at least about 1204.degree. C. A preferred ore is taconite.

  • Binder for metal-containing ores
    Patent number: 4919711
    Abstract: A binder useful for agglomerating a concentrated ore material in the presence of water comprising (a) a water-soluble polymer selected from the group consisting of alkali metal salts of carboxymethyl celluylose or carboxymethyl hydroxyethyl cellulose and (b) sodium tripolyphosphate, a process for agglomerating the concentrated ore material using this binder, and the agglomerated product of this process, are disclosed.
