A vacuum cleaner has an adjustable-height suction nozzle. A diaphragm switch is mounted in the housing inside the nozzle and determines a differential air pressure of the operating vacuum cleaner. Voltage source terminals are self-energizing with the rotation of a rotatable brush inside the nozzle and an indicator lamp is illuminated, or extinguished, upon developing a proper suction as establised by the proper adjusted height of the nozzle relative to the floor surface. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

An electrostatic spray device having a gun barrel formed with a powder delivery passageway connected to a source of particulate powder material, a nozzle mounted at the forward end of the gun barrel which is formed with a discharge opening for emitting coating particles, a deflector carrying an electrode which produces an electrostatic field in the path of the coating particles emitted from the discharge opening and a pattern adjustment sleeve carried by the gun barrel which is radially outwardly spaced from the deflector and discharge opening. Both the deflector and pattern adjustment sleeve are axially movable relative to one another, and relative to the discharge opening, to vary the width of the spray pattern of coating particle emitted from the discharge opening while controlling the concentration of the electrostatic field produced by the electrode, and, accordingly, the level of ionic bombardment of the powder particles, so as to obtain an optimum electrostatic charge on the coating particles emitted from the discharge opening.

Electrostatic liquid spray coating apparatus including a rotary atomizing cup of insulative material driven by an air turbine, is provided with a semi-conductive charging device extending through the cup, the inner portion of which is proximate the inner surface of the cup for contact charging liquid coating material supplied to the rear of the cup as it flows forwardly and outwardly over the rotating cup interior and contacts the charging device prior to atomization at the forward edge of the cup. A generally cylindrical insulative support body, housing a turbine and its associated air bearing and cup drive shaft, has a reduced diameter intermediate section which provides an annular cavity in which are located liquid coating and solvent valves for controlling the flow of liquid coating and solvent to the cup. The charging means in the cup is energized via a stationary conductor which terminates in closely spaced proximity to the outer portion of the charging device on the cup exterior which is electrically connected to the inner portion of the charging device on the cup interior via a series of semi-conductive posts which form the portion of the charging device extending through the wall of the cup between its inner and outer surfaces.
