  • Process for consolidating particulate solids and cleaning products therefrom II
    Patent number: 6689305
    Abstract: A bed of particulate solids including some hydrated materials can be converted by controlled irradiation with subinfrared electromagnetic radiation into a unitary porous solid that is mechanically strong enough for easy handling. When the particulate solids include typical mildly acid to alkaline cleaner materials, a block or tablet especially suitable for automatic cleaning machinery, with a very fast dissolution rate in water, can readily be obtained.
    Type: Grant
    Filed: January 14, 1994
    Date of Patent: February 10, 2004
    Assignee: Ecolab Inc.

  • Aqueous lubricant solutions based on fatty alkyl amines
    Patent number: 5062978
    Abstract: The invention relates to an aqueous lubricant solution based in part on a particular group of fatty alkyl amines, which aqueous solution is especially suitable for use as a belt lubricant for the lubrication of conveyor belts for bottles. The aqueous lubricant solutions in accordance with the present invention exhibit excellent clouding behavior and very good gliding action.
