|20130327453||METHOD FOR HOT STAMPING METAL - A method for hot stamping an iron based component in which the component is heated to a temperature sufficient to transform the component into austenite. The heated component is then positioned in an open stamping die and the stamping die is closed to mechanically change the shape of the heated component to a desired end shape of the component. At least one opening is punched in the heated component and, thereafter, the component is quenched at a rate and to a temperature sufficient to transform the component into martensite.||12-12-2013|
|20100102068||FUEL TANK AND METHOD FOR MAKING SAME - A fuel tank having a top shell with an outwardly extending flange about its outer periphery and a bottom shell also having an outwardly extending flange about its outer periphery. The top and bottom shells are dimensioned so that, with the top shell positioned on top of the bottom shell, an outer peripheral portion of the top shell flange flatly abuts against an outer peripheral portion of the bottom shell flange and these outer peripheral portions are secured together. A component support has an outer edge portion sandwiched in between the flanges at a position spaced inwardly from the flange outer peripheral portions. The flanges and the outer edge portion of the component support are then bent to a plane oblique to the component support to thereby mechanically lock the outer edge portion of the component support and the flanges together.||04-29-2010|
|20090072199||WATERBORNE CORROSION-RESISTANT COATING - A waterborne thermoset cured anticorrosion formulation includes a water dispersed or emulsified phosphonated or water dispersed or emulsified sulfonated epoxy resin that is cured with a phenoxy resin having a polyhydroxyl ether backbone and terminal alpha glycol moieties. Water is present as a predominant volatile in which the epoxy resin and phenoxy resin are present in a weight ratio of epoxy resin to phenoxy resin of between 0.1 and 3:1. An aqueous curative is provided to induce cure between the epoxy resin and phenoxy resin, A corrosion inhibiting metal salt is also present having a salt anion of phosphate, biphosphate or tetraborate and a metal cation with the proviso that the metal cation formulation as a whole is devoid of chromium, lead, cobalt, and cadmium. Ideal curatives include aqueous aminoplast crosslinkers, aqueous unblocked isocyanates, aqueous blocked isocyanates, and a mixture thereof. With the inclusion of electrically conductive aluminum or zinc particulate the formulation is rendered corrosion resistant as well as electrically conductive to make an inventive coating amenable to powder coating.||03-19-2009|
