  • Machine washing process for soiled textile articles
    Patent number: 4963158
    Abstract: Soiled textile articles are washed by the addition of a determined amount of a detergent concentrate containing surfactants to the textile articles to be cleaned while the textiles are dry or only damp. The aqueous washing liquor is formed by the gradual addition of water to the textile articles while they are rotated. At room temperature, the detergent concentrate is to a substantial extent a paste-to dough-like substance, stable in form, and is applied to the textile articles in such an amount that the major portion of the surfactants together with further detergent constituents, if desired, are applied to the textiles or on an article of textile provided with markings for the correct detergent dose, as a dosing aid.

  • Composition and process for activating metal surfaces prior to zinc phosphating and process for making said composition
    Patent number: 4957568
    Abstract: Activation of metal surfaces prior to phosphating can be improved by using aqueous dispersions of polymeric titanium(IV) phosphates in which at least 95% by weight of the polymeric particles have a particle diameter of less than 200 nm. This low particle diameter is attained by adding a titanium(IV)-complexing agent before or during an otherwise conventional reaction between a titanium(IV) compound, acid or phosphate, and water. The complexing agent is used in an amount of less than the stoichiometric amount, based on the titanium(IV) content. The best complexing agents are poly(aldehydocarboxylic acids), 1,1-diphosphonic acids, and/or the alkali metal salts of these types of acids.
