Abstract: A high-quality, fire-resistant, decorative finish for panels made of composite material, such as aircraft interior panels. Starting with a flat or complex contoured panel, a flame-retardant filler primer is applied to the panel surface. This filler primer is then sanded to a very smooth solid surface. In a separate process, a polymeric film is printed with a desired pattern or image. The polymeric film is then bonded to the primed panel surface using an adhesive. The non-printed side of the polymeric film is bonded to the panel. A thin highly durable polymeric coating (clear or tinted) is then applied to the exposed printed side.

Abstract: A fiber optic cable extends into the housing of an induction heater and has a sensing end positioned to confront a part being heated. Infrared radiation from the part is transmitted by the cable to a transducer. The transducer converts the infrared energy into an electrical signal that is used by a control circuit to control the heating operation. The control circuit has an internal electronic timer that is used in normal operation and to detect certain failure conditions. In normal operation, electromagnetic pulses are provided to the heater at a predetermined power level until the part reaches a predetermined temperature. Then the control circuit adjusts the power level to hold the part at the temperature for a brief holding period. The timer is used by the control circuit to detect failure to reach a desired temperature after a maximum delay and to detect dropping of the temperature below a minimum level during the holding period. The control circuit also detects overheating of the workpiece.
