Abstract: The present invention is directed to a method of forming a circuit assembly, such as including a radio frequency identification device (RFID), wherein first and second portions of an antenna of the circuit assembly are provided on respective first and second substrates, with the associated electrical circuit, having first and second electrical contacts on respective opposite sides thereof, positioned between the first and second substrates. Alternatively, first and second portions of an antenna of the circuit assembly are provided on a substrate, with the associated electrical circuit, having first and second electrical contacts on respective opposite sides thereof, electrically joined to the respective antenna portions. Highly efficient manufacture is thus promoted.

Abstract: A process is provided for substantially completely converting carbon monoxide in waste gas into carbon dioxide in a combustion chamber. This process comprises the steps of supplying fuel to the combustion chamber in an amount sufficient to maintain a temperature greater than the combustion temperture of carbon monoxide therein, feeding waste gas containing carbon monoxide to the combustion chamber, measuring the percentage of carbon monoxide in the waste gas, feeding free oxygen to the combustion chamber, exhausting the gas from the chamber, measuring the actual percentage of free oxygen in the exhaust gas, calculating an optimum percentage of free oxygen in the exhaust gas, and adjusting the volume of free oxygen being fed to the combustion chamber in an amount sufficient to produce the optimum percentage of free oxygen in the exhaust gas.
