  • Patent number: 6740126
    Abstract: A method for the application of durable press to textiles via the pre-treatment bleaching of a non-finished textile component followed by the application of a durable press finish is provided. The method comprises the steps of treating a non-finished textile component in an aqueous bleaching solution of hydrogen peroxide and a hydrophobic activator or hydrophobic peracid for a time sufficient to bleach the textile component followed by application of the durable press finish preferably via immersion in an aqueous solution of formaldehyde, a cross lining catalyst and a silicone elastomer forming material or a solution of alkylene urea and a crosslinking catalyst. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method allows significant savings in both energy and time due to the lower bleaching temperatures possible via the present method as opposed to conventional peroxide processing.

  • Patent number: 6296455
    Abstract: A pump enable system includes a variable-displacement piston pump having a displacement control device. The displacement control device controls displacement of pistons in the pump based on a position thereof, and a position control system in the pump controls a position of the displacement control device based on a load on the pump. An over-ride system selectively over-rides the position control system such that the displacement control device assumes a position which reduces displacement of the pistons in the pump.

  • Patent number: 5928701
    Abstract: The present invention relates to a process for making digestible fat free corn chips. The process for preparing the fat-free corn chips comprises:a. preparing raw corn chip pieces from a dough comprising a mixture of corn masa and a fat free filler selected from the group consisting of starch, protein and nondigestible fiber, and mixtures thereof; and water; andb. cooking said raw corn chip pieces in nondigestible fat at 300.degree. F. to 450.degree. F. (148.9.degree. C. to 232.degree. C.).
