Abstract: An apparatus and method for determining the heating value of gaseous fuels includes a mixing device (60) for establishing a mixture of air and the gaseous fuel of interest in known volumetric proportions. An electrochemical sensor (48) senses the products of combustions of the precise volumetric mixture and the output signal of the sensor is indicative of the relation of the mixture to a stoichiometric mixture offuel and air. This signal is used for adjusting the proportions of fuel and air in the mixture of interest until the sensor indicates that the mixture of known proportions is substantially stoichiometric. A microprocessor (70) determines the heating value of the fuel from a known relationship between the heating of the constituents of the fuel and the amount of oxygen required for stoichiometric combustion (Fig. 2)

Abstract: A welding rectifier is connected to an a.c. power supply. The rectifier delivers a pulsating voltage which during a part of a period is too low to maintain the arc established between a welding electrode and a work. A main winding of an ironcored inductor is connected in series with the rectifier, the welding electrode and the work. An auxiliary winding is wound onto the iron core and connected in series with a capacitor. The auxiliary winding is connected to the main winding so that the two windings, when passed by a current, supply ampere-turns in the same direction. The auxiliary winding and the capacitor are connected in parallel with the main winding and the arc. The capacitor is also connected in series with a charging rectifier connected to the a.c. supply. The capacitor is discharged through the auxiliary winding and the main winding into the arc, when the voltage delivered by the welding rectifier is too low to maintain the arc.
