    • A metering valve to be fitted to an aerosol container comprises a dispensing member (6) in the form of a tube and a metering member (2) in the form of a cylindrical cup which receives the inner end of the tube (6). The dispensing tube (6) is slidable in an opening in a valve housing (11). A bellow (1) extends between the inner end of the dispensing tube (6) and the housing (11) to seal against escape between the dispensing tube (6) and the opening in the valve housing (11). The bellows (1) is integral with the dispensing tube (6). The inner end of the dispensing tube (6)/bellows (1) seals against a seat (9) in the floor of the metering cup (2). The upper end of the metering cup (2) seals against a gasket (3) which lies against the upper end of the bellows (1).

    • A load 2 is connected to an A.C. source via a capacitor 1 which acts as a voltage dropping device. The load current may be varied by switching in different capacitance values (Fig. 1c). A clock-operated switch (14) may be used to bypass the capacitor 1 at certain periods of the day (Fig. 2). The load may be an a.c. load, or a d.c. load may be supplied via a half-wave or full-wave rectifier (Fig. 4). A series resistor 3 may be provided for current limiting, and the output voltage may be limited by means of a zener diode 5, an auxiliary load resistor 7, or a capacitor 9 connected across the input of bridge rectifier 4 and in series with capacitor 1 across the supply. A switched jack socket (10), (Fig. 1d), may be used to prevent a rise in voltage at the output terminals when the load is removed. The load may be an incandescent lamp, a heating element, a vacuum- tube filament string, an electroplating device, a radio, or a refrigerator open-door alarm (Fig. 6).
