Abstract: A process for controlling a gas blower burner in which an ionization electrode sends an electrical variable derived from the combustion temperature or the lambda value to a control circuit, which compares this variable with a selected electrical set point and adjusts the gas-to-air ratio (lambda value) to a corresponding lambda set point. To compensate the effect of a condition-dependent change in the proportionality between the lambda value and the electrical measured variable derived from it on the control in such a way that the desired lambda set point will be maintained, a calibration cycle is run from time to time. The lambda value is reduced from a value of >1 during this cycle. The maximum obtained at lambda=1 is stored. The electrical set point is adjusted with this maximum.

A pair of similar electrode structures are arranged in series on the waveguides, the electrodes of the two structures being separately addressable by binary electrical signals. The phase shifts induced in the light propagating along the parallel waveguides by voltages applied to the separate electrode structures allows the output to take values of 0, 1 or 2 for binary inputs applied to the structures.
