Abstract: A method and apparatus for sterilizing preformed cartons prior to filling is disclosed. The interior of the cartons are first sprayed with a solution of hydrogen peroxide. The cartons are then treated with heated air to remove the hydrogen peroxide. The heated air is applied by means of a hollow mandrel having nozzles at one end. The mandrel corresponds generally to the shape of the carton. When the mandrel is inserted in the carton, air is directed against the interior side walls and bottom of the carton, and is exhausted from the carton by flowing upwardly between the side walls of the mandrel and the side walls of the carton.

Abstract: A system for identifying the location of an aircraft on the surface of an airport includes a plurality of low power FM transmitters located along the boundaries of runway and taxiways. Each transmitter provides an FM signal having a common carrier frequency and each FM signal is encoded with unique information indicative of the position of the transmitter on the airport surface. Aircraft and other vehicles containing a conventional FM receiver "capture" only the strongest signal and process the "captured" signal to determine which transmitter was the source of the signal and hence where the aircraft is on the airport surface.
