  • Patent number: 5485985
    Abstract: An apparatus for metallurgically heat treating a plurality of discrete individually movable aluminum alloy parts includes a plurality of successive stations for heat treating the parts. The plurality of stations are arranged in a line of travel. Infrared radiation lamps are provided at each station. A conveyor mechanism places and holds a part in a station for heat treatment. The conveyor moves the part to a subsequent station for further heat treatment. The conveyor mechanism holds the part stationary relative to the line of travel while the part is in a station being heat treated.

  • Patent number: 4943447
    Abstract: A process for heat treating a coating applied to an automobile body is disclosed. The process is carried out with apparatus which includes radiant heating elements for generating radiant heat in a predetermined path and convection heating elements for generating the flow of heated air. The method comprises the steps of positioning a freshly coated automobile body within the apparatus and heating the body with the radiant heat for a time sufficient to set the coating on Class A surfaces of the body. After the Class A surfaces are set, heated air is flowed around the body to heat the body and cure the coating on the Class A surfaces and the non-Class A surfaces.
