Abstract: A method is described for batchwise heat treatment of goods to be annealed which are heated in a heating chamber after scavenging air with a scavenging gas under protective gas to a predetermined treatment temperature, with the protective gas being conveyed through the heating chamber depending on the occurrence of impurities in different quantities. In order to enable the economic use of protective gas, it is proposed that the protective gas which is withdrawn from the heating chamber after the main occurrence of impurities and which is loaded with a residual quantity of impurities is conveyed, optionally after intermediate storage, into the heating chamber during the main occurrence of impurities of a subsequent batch before non-loaded protective gas is introduced into the heating chamber.

Abstract: A method for turning a three-phase alternating current motor on again, after it has been separated from a supply voltage, if a residual field voltage induced by a rotor residual field is present, and to an electrical circuit for implementing the method. The time progressions of the residual field voltage and the supply voltage are recorded, and the phase difference between the voltages is calculated in advance from the time progressions. A time point ts is determined, at which the phase difference goes below a predetermined maximum value ??max. A switching command for applying voltage is triggered at a time interval that corresponds to a predetermined switching time delay ?s, before the time point ts is reached, so that the motor is connected to the supply voltage approximately at the time point ts. The electrical circuit has a measurement value detection device, a microcontroller and a direct current setting device.
