Abstract:
A powder spray coating discharge assembly (230, 260, 216, 228, 232) for connection to an electrostatic spray coating gun (210), the gun (210) having a gun body (212), means for connecting to a supply of coating powder and means for supplying a voltage (20) at first and second potentials respectively to first (292) and second electrical connections (294) each for connection to a respective one of a discharge electrode (232) and a counter electrode (260), the means for supplying the voltage (20) comprising: a variable voltage power supply (1 14) having an input connected to an electrical power source (110), an output connected to each of the first and second electrical connections (292, 294), a control circuit (128) for controlling the variable voltage power supply (20) and means (120) for sensing an output load, wherein the control circuit (128) is adapted to adjust the variable voltage power supply (20) to reduce the voltage and current in proportion to a sensed increase in load, or vice-versa.
Abstract:
A gantry tower spraying system with a cartridge/receptacle assembly includes a gantry and a spray assembly coupled to the gantry to allow for translational movement of the spray assembly along the gantry. The spray assembly includes a receptacle for receiving a cartridge containing a cosmetic liquid for skin treatment, and a spray nozzle coupled to the receptacle for receiving the cosmetic liquid and dispensing the cosmetic liquid in a spray. The receptacle has an inner surface of a size and shape to generally conform to a size and shape of a portion of an outer io surface of the cartridge. The spraying system can further be provided with an oscillation mechanism adapted to cause oscillation of the spray nozzle. The bottle can be provided with a keying mechanism for engaging a corresponding key structure of the receptacle.
Abstract:
System, method and equipment for the application of plant protection products under controlled post-harvest conditions, preferably on dessert grapes and other fruit, by means of spraying equipment with an electrostatic effect which expels through spray nozzles whose droplets are negatively charged, being attracted by positive charges of the object to be treated, thereby achieving uniform covering with excellent penetration in the bunch of fruit. The treatment is particularly suitable for controlling fungal diseases and especially the disease called acid rot.
Abstract:
The present invention relates to (with reference to Figure 1) an electrostatic fluid atomiser which has a fluid inlet (2) and a fluid channel (3) leading fluid to a wall (6) in which orifices (100) are formed. Fluid passing out of the orifices (100) is atomised into droplets which fall into a first set of larger droplets (12) and a second set of smaller droplets (13) . Two charging electrodes (4,6) charge fluid passing through the channel (3) . A droplet separator (200) has a separator electrode (16) which applies an electrical force on the droplets and deflects the smaller droplets (13) to be collected by a droplet collector (15) while the larger droplets (12) continue undeflected out of a droplet (201) of the atomiser.
Abstract:
The invention is directed to a corona charging device (100) having a powder feed (102) with an outlet. The device has an internal charging cavity (103) having an inlet (101) and a charged powder outlet. The device also includes a rotating ground electrode and a ground electrode cleaner.
Abstract:
An in-home method for treating a fabric article in need of treatment and a new to the world, in-home, self-contained, stand alone fabric article treating apparatus, such as a "cabinet"-type of apparatus, useful in such method is provided.
Abstract:
In a method of electrostatically applying a powder material to a solid dosage form, charged powder material is applied to a photoconductive drum (3), is transferred to an intermediate belt (4) and then to a solid dosage form (5). The belt (4) makes contact with the solid dosage form (5).
Abstract:
Disclosed is an apparatus and method for electrostatically coating a human (11) with a coating composition. In one embodiment, the present invention includes an enclosure (3); a mount (6) positioned on the enclosure; an electrostatic nozzle (7) connected to the mount, the electrostatic nozzle for passing the coating composition; and a grounding connection (4) positioned inside the enclosure, the grounding connection capable of electrically grounding the human; wherein the coating composition passed through the electrostatic nozzle is depositable upon the human. Furthermore, in another embodiment, the enclosure includes a first wall wherein the mount is positioned on the first wall; and a second wall positioned substantially opposite the first wall, the second wall including a portion curved about an axis.
