Abstract: The invention relates to a reversible counter to which count-up and count-down impulses can be fed. Blocking means is provided in which the exceeding of the upper and lower limits of the counter is prevented. The blocking means is incorporated in a NAND element associated with the impulse input. The blocking means is influenced by the outputs of the binary stages of the counter being monitored and by the counting direction signal.

Abstract: The invention relates to single phase asynchronous motors in which a bimetal switch for opening the auxiliary circuit is in the circuit of the main winding of the motor. The bimetal switch is initially caused to open the auxiliary circuit by heat produced in a heating resistor in the auxiliary circuit. The bimetal switch is caused to remain open during operation of the motor by heat produced in the bimetal switch by reason of the current for the main circuit being directed through the bimetal switch.
