  • Patent number: 7427037
    Abstract: A showerhead facilitating draining of water retained following shut-off. The showerhead includes a housing swivelably fitted on a ball-adapter which in turn includes an integral threaded segment for attachment to a water feed line. An air pathway is formed to extend from inside to outside the ball-adapter where it opens to generally atmospheric pressure. A flexible check valve in the form of an annular skirt is retained by an integral ring portion where the ball-adapter is threaded to the feed line. Under water-flow pressure, the skirt expands, blocking the passage. Upon shut-off, the skirt withdraws, instantly opening the air passage. Opening the showerhead to atmospheric pressure relieves the normally occurring suction effect which keeps water from draining completely from the showerhead spray holes. Thus avoiding the widespread problem of trapped water slowly evaporating and leaving behind stubborn and unsightly mineral deposits that eventually build up to clog showerhead spray holes.

The device for dispensing and restricting flow of a gas through the nozzle may be either a bypass piping having a flow control means or a stopper that operates to provide a constant but low volume flow of an inert gas such as nitrogen to the nozzle to prevent particle build up or crystallization from occurring.

  • Patent number: 6679441
    Abstract: The invention concerns electrohydrodynamic spraying means enabling electrohydrodynamic spraying, in the air and at atmospheric pressure, of liquids with high surface tension such as water. The means are characterised in that they comprise at least a liquid dispensing conduit (1) whereof the dimensions of the external diameter and of the internal diameter, at the liquid exit point, correspond to an appropriate ratio. Said means can be advantageously used for depolluting aerosol effluents, or transformable into aerosols.

    Abstract: A power supply for an electrostatic powder spray gun is formed in the shape of a hollow cylinder with a central passageway therethrough. A powder tube is slideably inserted through the central passageway of the power supply thus providing a more compact and symmetric spray gun profile. The power supply may be a voltage multiplier, for example.

  • Patent number: 6354522
    Abstract: In an electrostatic sprayer, a pulsating voltage developed using a battery or a generator as a power supply is stepped up using a step-up transformer. A resultant high-voltage pulse is rectified and applied to an electrostatic electrode. A spray jetted from a spray nozzle is thus electrified. Herein, the step-up transformer is located near the spray nozzle. Owing to this structure, a high voltage produced by the step-up transformer can be applied to the electrostatic electrode with a loss minimized.

  • Patent number: 6227466
    Abstract: An electrostatic spray module for applying agricultural liquids such as a pesticide to crops where, externally to the spray module the number of connections is reduced to three, one for the liquid pesticide, one for compressed air and one for a low voltage signal. Internally to the spray module, the low voltage is converted to a high voltage signal, which is, along with the pesticide and the compressed air delivered to one or more electrostatic spray nozzles using only two electrically conductive pipes, a gas delivery pipe and a liquid delivery pipe. The nozzles fit into the gas delivery pipe and draw the compressed air through gas channel openings in the side of the nozzles. The gas delivery pipe doubles as the means to delivery the high voltage signal to the nozzles. Each nozzle has a liquid feed from the liquid delivery pipe, which carries ground voltage, maintaining the liquid at ground voltage. The grounded liquid merges with the compressed air in the nozzles to form an atomized liquid.

  • Patent number: 5938126
    Abstract: A powder spray coating system includes a power source and an electrical supply line connected to the power source. A spray gun sprays powder in a spray pattern onto a part. The spray gun includes an electrode which charges powder as the powder is dispensed from the gun toward the part. The electrode is connected to the electrical supply line. A first current sensing device is located in the electrical supply line measuring gun current between the power source and the electrode. An ion collector or ABI probe is mounted with the gun for collecting free ions produced by the electrode. The collector has a forward portion positioned near the spray pattern and is spaced from the electrode. The collector is connected to a ground line. A second current sensing device is located in the ground line measuring back current between the ion collector and ground. A controller is connected between the power source and the electrode to control the gun current.

  • Patent number: 5916640
    Abstract: An atomizer has a chamber holding a liquid containing particles of a desired material. Aerosol particles are formed by using an aspirating nozzle or ultrasonic vibrator and the aerosol particles are carried in a gas flow. The aerosol particles are treated by increasing the charge on the aerosol particles by contact with a high voltage electrode and the aerosol particles are passed through inertial separator stages to remove large aerosol particles from the flow so they are not discharged from the atomizer.
