Abstract: A nozzle apparatus (10) and method for electrically charging and dispensing fluids and other flowable materials, comprising a fluid reservoir (12) and a housing (14). The housing (14) includes walls which define a chamber (28) having an elongated slot (32) at the tip (33) thereof. The slot (32) is resiliently compressible. The reservoir (12) communicates with the chamber (28) such that the fluid is introduced into the chamber (28) at a controlled rate and a low hydrostatic pressure. A shim (34) is placed within the chamber slot (32) partially occluding fluid flow through the slot (32). The shim (34) and the amount of compression and expansion of the slot (32) define with precision the size and shape of the slot (32). The shim (34) and fluid are electrically connected to a high voltage source (18) through the housing (14). The fluid forms a meniscus (50) about the housing slot (32) whereby upon actuation of the high voltage source (18), the fluid is dispensed as one or more charged fluid paths (20) or a plurality of charged droplets.

Abstract: Electrostatic cup lubricating process and apparatus (15) in which cup-shaped can bodies (36, 37, 38, 39) are controllably conveyed in spaced relationship to each other through a lubrication application chamber (20). Lubricant is atomized to particle sizes permitting them to be gas borne and are introduced into such chamber so as to present the desired dispersion of charged lubricant particles about the travel path (11, 12, 13, 14) for can bodies (36, 37, 38, 39). The can bodies (36, 37, 38, 39) are electrically grounded individually during passage through such lubricant application chamber (20) so as to attract the charged particles resulting in the desired lubricant coating. Endless loop conveyor means (80, 81, 86, 87) are provided with adjustable features enabling a travel path (11, 12, 13, 14) to be adapted to differing dimension can bodies (36, 37, 38, 39).

Abstract: Electrostatic coating blade (11) for coating objects with a liquid. The blade consisting of two halves (12a, and 12b) held together by bolts (15). A central passage (14) is provided that receives liquid from a reservoir (not shown) and a narrow channel (16) can conduct liquid to a discharge edge (17). The blade can be used either horizontally (as is customary with electrostatic coating blades) or vertically. The blades (11) are particularly useful when vertically disposed to coat oil onto the edge of coils of sheet metal.

Abstract: A carriage (2) moving on the ground (1) comprises a support column (3) to which are adjustably fixed heightwise a support (5) integral with a container (6) and spraying guns (8) held by arms (7). The support (5) is connected to a compressed air source by means of a flexible hose (11) and to a high voltage source by means of a collectorcable (13) which is connected to each gun (8) by means of a high voltage cable (14) passing through each hollow arm (7). Each arm (7) is fixed by a mandrel (47) with a longitudinal motion and pivotingly at least about one axis. The gun (8) is supported by the free end of the arm (7) so as to pivot at least about one transverse axis, and is connected to one of a plurality of orifices (32) of the container (6) by means of a flexible hose (44) and an injector (40). The container (6) comprises a stirrer and processing means associated with each orifice (32). The guns (8) which are adjustable independently of each other may be operated and controlled independently by means of injectors (40) so that a variation of the spraying of one gun has no influence on the spraying capacity of other guns.

Abstract: A cylindrical rod (3) longitudinally movable is arranged centrally in relation to the spray (2) of a powder spraying pistol (1). A conical deflector (5) is mounted on its free end. The lateral surface (9) of the deflector forms a sharpe edge (11) with the conical concave front face (10). In the central exhaust channel (12) of the deflector (5) a rinsing nozzle is arranged provided with an outlet approximatively radial for the rinsing air supplied by a pressurized air source (19). The rinsing tip comprises a head (14) in the form of a mushroom forming a deflecting body disposed adjacent to the exhaust channel end (12). The nozzle may also be made in the form of a rotation nozzle by means of a sharpe annular edge and a whirling chamber or of a helical guiding flange. The rinsing air flows continuously along the front face (10) thus preventing any powder packing at this place. A switch valve (18) controlled by a key (20) can switch automatically the exhaust channel on a source of fire extinguishing gas (21) which blows the gas in the spraying region where there is the greatest danger of inflammation.

Abstract: An electrostatic particle spray gun having, in one preferred embodiment, a conical deflector of insulative material mounted in the nozzle in the particle path for forming a conical particle spray pattern. A resistive sheet connected to a high voltage electrostatic supply is sandwiched between the forward and rearward ends of the deflector, leaving only the perimeter of the sheet exposed at the peripheral region of the conical deflector. The perimeter of the resistive sheet functions as a multi-point circular electrode for charging the particles such that improved coating transfer efficiencies are achieved. Also, because of the resistive nature of the resistive sheet, the sheet constitutes a resistor in the electrical current path between the center of the sheet where it connects to a high voltage terminal and the circular periphery of the sheet which serves as the multiple point charging electrode, thereby minimizing unsafe electrical discharges should the electrode inadvertently approach a grounded object.

Abstract: A high-voltage generator for electrostatic sprayer device is disclosed whereby a frequency-clocked power amplifier is employed for the feed of a transformer connected preceding a high-voltage cascade, this power amplifier being connected to a controllable low-voltage d.c. voltage source and to a controllable frequency generator, whereby the control of the d.c. voltage source and of the frequency generator ensues by a microcomputer such that the transformer is optimally matched (or: balanced) for all voltages appearing at the high-voltage output of the cascade.
