  • Patent number: 6946194
    Abstract: A method and system for determining weather strip fit for the closure panels of a vehicle includes a flexible carrier with a transferable disclosing agent disposed on the flexible carrier. The flexible carriers may be applied to a closure panel of vehicle when the panel is in an open position, with the panel then being closed so as to allow the disclosing agent to either be transferred to the fixed side of the opening, or to be merely dislodged from the flexible carrier. In either case, the pattern of interference fit between the weather strip and the closure panel is then disclosed.

  • Patent number: 6675625
    Abstract: The present invention discloses a method of correcting the shape of a spray-formed article which has a concave bowing relative to the working surface of the article. Specifically, deviations of such articles from a desired predetermined shape are corrected by applying sufficient heat to a non-working surface to permanently remove at least a partial amount of the concave bowing while leaving the working surface substantially unmarred. This process is repeated iteratively until the article achieves the predetermined shape.

  • Patent number: 6091043
    Abstract: A method of electric arc spraying metal upon an article. The method comprises providing an article to be sprayed, providing a supply of fusible metal feedstock, providing a metal feedstock feeding device, and providing a substrate of conductive heat resistant material. The substrate has a centrally disposed orifice extending therethrough. A source of electrical current is provided having a first electrode electrically coupled with an end of the metal feedstock, and a second electrode electrically coupled with the plate of conductive material. The source of current is activated to establish an electric arc between the metal feedstock and the plate of conductive material. The electrical arc creates a droplet spray of metal from the metal feedstock. The droplet spray is directed through the orifice in the substrate towards the article. The power supply is periodically pulsed between a first current and a second current.
