Abstract: A circuit arrangement for controlling the amplitude of an audio IF signal from a television signal which also comprises a video signal, by means of a device by means of which the controlling is effected with a first control time constant, is described. To bring the picture and sound reproduction into a stable state with equal rapidity after a channel change in such a circuit arrangement without impairing the transmission quality of the audio signal, the device is constructed to be switchable in such a manner that the controlling is effected with a second control time constant when the level of the picture signal assumes a value within a predetermined value range. <IMAGE>

Abstract: A welding arc stabilizer (101) includes a source of high voltage (102) and a switch (103) for switching the source of high voltage across an electrode (106) and a workpiece (107) in the event the arc rectifies. The high voltage is switched across the electrode (106) and workpiece (107) within the completion of the half cycle in which rectification occurred. The source of high voltage (102) includes a resonant LC circuit. An arc sensing circuit (104), including a resistor (206), a capacitor (207), and a zener diode (205) is provided in parallel with the arc. In the event the voltage applied to the electrode (106) and workpiece (107) exceeds the zener diode breakdown voltage, indicating the arc has rectified, an SCR (203) disposed between the resonant circuit (102) and electrode (106) or the workpiece (107) is turned ON, thus connecting the source of high voltage (102) between the electrode (106) and workpiece (107) to re-establish the arc.

Abstract: An actuator (1) for a liquid spray pump (3) is provided with a skirt (38) which co-operates with a body (39) of the pump to compress a volume of air (32) during pump actuation. Air compressed by this action is ejected from an air injection channel in the vicinity of a liquid spray emerging from a first nozzle (12) defined by the actuator. A second nozzle (17) is connected to the actuator externally of the first nozzle (12) to define an air gap (30) therebetween and the air ejection channel (31) communicates with the air gap such that in use both the liquid spray and the compressed air are dispensed through the second nozzle aperture (18). Primarily intended for dispensing water based products, the effect of the compressed air is to assist in the evaporation of water contained in the liquid or any other volatile liquid dissolved in a liquid product to be dispensed in aerosol form.

Abstract: The start-up and commutation procedure applies to synchronous machines having a rotor with fixed magnetisation, a stator with a three-phase winding and an incremental transducer with a reference pulse signal. When the machine is switched on, currents with differing phases are applied to the stator three-phase winding in order to determine the maximum torque, and thus the stator current phase when the machine first turns. Up to recognition of the reference pulse signal, the stator current phase is given by determination of the relative position of the rotor to the stator. Following the reference pulse signal, the absolute rotor position is determined, and the preset rotor magnetising direction offset angle is used to define the circulating phase of the stator currents.

Abstract: The method for controlling foam slag formation involves supply of carbon without possible excess amounts in such a way that the arcs are at least partially enveloped. Acoustic emission within the rage of double grid/supply frequency is used to judge about the slag formation process. The supply rate of carbon is controlled on the basis of the acoustic emission - which is automatically registered and frequency-selectively evaluated with respect to its amplitude, at least over a part of its spectrum - from the furnace. The supply rate is increased/decreased respectively for sound levels above/below thresholds specified by a control unit. <IMAGE>
