摘要： A spray-coating device for spraying liquid or powdered coating material on articles includes a transformer for stepping up an alternating voltage and a voltage multiplier circuit for converting the output of the transformer to a high DC output for driving a charging electrode in the spray-coating device. The alternating voltage for the transformer is obtained from a controllable source of alternating voltage which produces a sinusoidal voltage whose frequency is constantly adjusted such that the voltage and current flowing through the transformer are in phase with one another. This assures that the transformer is operated at its resonant frequency.

摘要： An improved control cable terminal for an electrostatic spraying gun includes a magnetically operated reed switch and an insulating body encapsulating both the switch and control wires at the gun end of the control cable. The body defines a switch plug insertable into the gun in operative relationship with a magnetic trigger element. Control cable plugs and receptacles are eliminated as are stresses on the control wires and reed switch. A bracket secures the insulating body to a tool removable coupling holding an electrostatic cable in the gun. The bracket prevents removal of the control cable switch plug, except by tool removal of the electrostatic cable coupling nut.

摘要： Safety device for an electrostatic painting plant using liquid coating products which are very electrically conductive, such as hydrosoluble paints or liquid enamel. An electrically insulating enclosure surrounds the container for the liquid coating material and has a latching device enabling the opening of the enclosure cover to be carried out only in a predetermined sequence, the first step of which causes the grounding of the paint container. The arrangement is such that the container can be disconnected from the ground only after the insulating enclosure cover has been replaced.

摘要： In a pulse power source for applying a pulse voltage to a capacitive load; a series resonance circuit capable of generating transient oscillation is formed of the capacitive load adapted to be applied with the pulse voltage, an inductance for generating transient oscillation and a power source capacitor; the capacitive load is charged from the power source capacitor by first closing one of two switch elements provided in the midway of the resonance circuit, that is, a load charging switch element to make the voltage across said capacitive load rise up to about twice the voltage across the power source capacitor after a period equal to about 1/2 of a transient oscillation period of said series resonance circuit, to form a rising edge of the desired pulse voltage; then reversely, the power source capacitor is charged from the capacitive load by closing the other switch element, that is, a charge recovering switch element after first said one switch element has been closed to make the voltage across said capacitive load fall down, to form a falling edge of the desired pulse voltage; and further a residual charge on said capacitive load is discharged by closing still another switch element provided in parallel to said capacitive load, to improve the falling edge of the desired pulse voltage; whereby a steep pulse voltage can be applied to said capacitive load with a low power loss.

摘要： A safety power supply system for electrostatic spray coating utilized high frequency (audio or radio frequencies) rectified DC pulses to provide the high voltage between an electrode on a spray gun and work to be coated. A high resistance direct electrical path to ground is provided for all parts of a coating system charged to high voltage during coating operations including highly conductive coating materials. For manual spray guns small electrodes or the atomizing edge of a coating material provides the electrode making it virtually impossible for an operator to come in contact with high voltage charged parts before a charge is substantially bled to ground.

摘要： A pulsed powder application system for electrostatically powder-coating a substrate comprises an applicator bed means, a fluidizing means, and a pulsing means. The pulsing means is actuable during a coating time to effect ionization of electrostatic powder particles so as to cause the establishment of an electric field attracting the particles to the substrate, and actuable during non-coating times to cause the establishment of a reverse electric field attracting the ionized particles away from the substrate. A feeder bed means and an associated fluidizing means are provided for holding the electrostatic powder prior to usage for coating by the applicator bed means.

摘要： A high voltage electrostatic spray coating power supply which turns-off automatically when an overvoltage and/or overcurrent is detected, thereby reducing electrical shock and ignition hazards when spraying in an explosive atmosphere. Included is an unregulated DC supply, a DC voltage regulator, an inverter, and a multiplier of the capacitor/diode type which applies high DC voltage to an electrostatic spray gun. Ground return current from the multiplier output to a common internal ground lead is monitored and if it exceeds a predetermined selectable maximum is effective, via a turn-off circuit, to a) turn-off the DC regulator and b) short-circuit the regulator output and inverter input to the common ground. This prevents power transfer between the unregulated DC source and the voltage multiplier, as well as discharges electrical energy stored in the regulator smoothing capacitors and in the multiplier transformer. An overvoltage circuit is also included to independently turn-off the power supply when the regulator output voltage exceeds a predetermined maximum.
