  • Pretreatment of aluminum surfaces with chrome-free solutions
    Patent number: 6562148
    Abstract: In a method for the pretreatment of work pieces having a surface made of aluminium or aluminium alloys, for non-cutting shaping and/or the connection by welding or gluing to work pieces as well as for a subsequent permanent corrosion-preventing treatment, the work pieces are subjected to a three-stage treatment by a) rinsing with an aqueous, acidic solution containing a mineral acid, b) rinsing with water, c) bringing them into contact with an aqueous, acidic solution which is chromium-free and polymer-free and contains Ti and Zr as complex fluorides in a weight ratio of Ti:Zr of 2:1 to 1:2, in such a way that, after the subsequent drying off, a layer weight of 2 to 15 mg/m2 (calculated as Ti/Zr metal) results, wherein depending on the type of application, solutions having different concentrations and different pH values are used.

  • Adjustable drive train and component cleaner brush
    Publication number: 20030075202
    Abstract: An adjustable brush for cleaning a drive or sprocket chain has a C-shaped toolhead fixed to a handle with an opposing cleaning element. The length of the handle sufficiently keeps users hands away from the chain during cleaning, and provides a means for the opposing cleaning element to clean generally inaccessible areas. The toolhead defines a chain passage recess having a plurality of inner sides. Each inner side has projecting retaining members to define a brush block cavity adapted to removably receive a brush block element such that a cleaning member formed thereon projects into the recess. Likewise, the opposing cleaning element has a pair of retaining members projecting therefrom to define a brush block cavity adapted to removably receive a brush block element.
