  • Publication number: 20040094424
    Abstract: A method for applying a metal coating to graphite structural members, in which a galvanic metal layer is deposited after said graphite structural members have been anodically etched in an alkaline etchant. The metal coating can serve as a basis for solder connections and can be employed for creating electrical contacts or for mechanically fixing the graphite structural member or it can fulfil other demands on the surface (e.g. abrasion resistance).

  • Publication number: 20030079997
    Abstract: A method for coating a light metal alloy component to form a protective layer comprising Sn. First, a surface of the light metal alloy component is cleaned and passivated. A layer comprising Zn is formed on the surface, and a layer comprising Sn is deposited. An intermediate layer is preferably deposited between the Zn-containing layer and the Sn containing layer. The Sn-containing layer may additionally be varnished.

  • Publication number: 20030056807
    Abstract: A surface of a light-metal alloy is anodically polarized in a cleaning process. The surface is cleaned with a solution containing phosphoric acid, alcohol, and optionally fluoride. Additionally, the surface is passivated in an oxidizing process using, for example, fluoride ions or an aqueous oxidizing agent. Preferably, the light-metal alloy has a relatively high Al or Mg content. This method is suitable for preparing the surface for a subsequent coating operation.

  • Patent number: 6224090
    Abstract: An airbag cover in a dashboard, a steering wheel hub cover, or door panel with at least one predetermined breaking line whose shape is substantially determined by a line-shaped weakened portion. The line-shaped weakened portion is a perforation line extending until approximately below the surface visible to the vehicle passengers. This perforation line is advantageously a curve alternating around the predetermined breaking line and is at least similar in shape to the structure of the visible surface.

  • Patent number: 5957388
    Abstract: The invention relates to a container for flowable cleaner products, particularly for liquid thixotropic WC bowl cleaners of which the thixotropic properties cause the liquid WC bowl cleaner to adhere to vertical surface. It is the object of the invention to provide a container having a spray head which causes the flowable cleaner product, and particularly the afore-said WC bowl cleaner, to be distributed in an optimum manner and which at the same time can be sealed and closed in a child-proof manner. To this end, the container is equipped with a spray head which consists of a cylinder-like basic body and of a mandrel-like body having a plurality of spray orifices, with the geometry and the relative arrangement of the cylinder-like and mandrel-like bodies being such as to enable the required optimum distribution to be obtained, with a special design of the closure cap providing for child-proof sealing and a releasable engagement thereof with the spray head.
