摘要： An electrostatic spray gun including a housing for receiving a replaceable fluid container, a nozzle from which fluid is to be sprayed, apparatus for expelling the fluid from the container and a high voltage generator for applying electrostatic potential to the fluid to form an electrically charged atomized spray at the nozzle. The replaceable fluid container is externally insulating and the electrical path from the generator passes through the fluid entering it at a point remote from the nozzle. A piston is employed to expel the fluid from the nozzle during spraying. The electrostatic spray gun has the advantage that it does not employ propellants and the paint need not be stored in a flexible plastic container thereby preventing loss of solvent during storage.

摘要： An electrostatic device for spraying liquids comprises a nozzle in the form of a wick which is contacted with a reservoir containing the liquid to be sprayed, high electrical potential being applied to the liquid in the vicinity of the spraying tip of the nozzle whereby the liquid is drawn out preponderantly under the influence of electrical forces into ligaments which break up to form a spray of electrically charged liquid droplets. The wick is fabricated from sheet of a resiliently deformable polymeric foam material of open celled structure and an edge of the sheet material is profiled to form a plurality of sites at which liquid ligaments can be produced. Typically a toothed profile is employed in which a plurality of teeth form the sites at which ligament formation occurs.

摘要： An electrostatic spraying device in which liquid emerging from an outlet (24) of the device nozzle (12) is subjected to an electrical field sufficiently high for the liquid to be drawn from the outlet as one or more ligaments which break up into charged droplets to form the spray. In order to provide shock suppression, the electrical field is produced by means of high voltage circuitry having a bi-polar output with a frequency no greater than 10 Hz.

摘要： Liquid to be dispensed is supplied to a dispensing nozzle (88) from a compressible container (30) such as a sachet with a valve-controlled outlet (66) by compressing the sachet through the agency of a pad (46) of resiliently deformable material. The dispensing device is embodied in a hand held unit having a trigger (102) and electrical circuitry (91, 96, 106, 98, 106) for applying high voltage to the liquid in order to effect dispensing of the liquid in the form of an electrostatically charged, atomised spray.

摘要： A method of making a liquid crystal device comprises producing, for example by means of electrostatic spraying, ligaments of a curable liquid which are deposited as such or as droplets (as a result of breaking up of the ligaments) on a sheet which is to form one boundary wall of the device. Curing of the liquid may be initiated while the liquid is in flight and completed after deposition. Liquid crystal material is applied to the deposited ligaments or droplets and a second sheet is laminated with the first sheet to encapsulate the liquid crystal material. The deposited ligaments or droplets serve to space the sheets apart and/or provide surfaces with which, in the field-off condition, the liquid crystal molecules can align in directions different to the direction of alignment induced by application of an electric or magnetic field.

摘要： An electrostatic spraying device in which liquid emerging from an outlet of the device nozzle (12) is subjected to an electrical field sufficiently high for the liquid to be drawn from the outlet as one or more ligaments which break up into charged droplets to form the spray. The device is adapted for the spraying of targets which are conventionally difficult to coat electrostatically, eg. targets of insulating material. This is achieved by the use of circuitry (18, 20, 22, 24) which generates a bi-polar high voltage output having a frequency such that successive clouds of particles are charged with opposite polarity but do not discharge each other in flight. In this way, the charge applied to the particles is effective to assist seeking of the target without leading to build-up of charge on the target.

摘要： An electrostatic spraying apparatus is in the form of a device suitable for hand held use. The device uses a high voltage generator of the rectified pulsed type and includes an earth return path which is completed via the operator through a contact (38) associated with the hand grip (4) of the device. Resistance (36), typically of the order of 50 megohm, suppresses pulsed electrical sensations that may be experienced by the operator in the event that the nozzle (12) is contacted with an earthed object, and the nozzle (12) is designed so that the liquid therein presents, by virtue of the length and cross-sectional area of a liquid conducting passage(s) in the nozzle, a high resistance between the voltage generator (26) and the nozzle thereby reducing the energy that can be drawn to earth by electrical discharge.

摘要： A liquid crystal device comprises a layer of fibers or filaments (15) permeated with liquid crystal material, the layer (15) being located between electrodes (13, 14) by means of which an electric field can be applied across the layer to vary the transmissivity of the liquid crystal/fiber composite. The diameters of the fibers/filaments are selected so that the light transmissivity of the composite has reduced sensitivity with respect to mismatch of the refractive indices of the liquid crystal and the fibers/filaments.

摘要： An electrostatic pump or pumping liquids having a resistivity in the range of 10.sup.10 to 10.sup.7 ohm cm has a pump housing. The pump housing includes a passageway through which the liquid is pumped, and a single injection electrode disposed upstream of the passageway. The electrode has a sharp electrically-conducting tip. A constriction in the region of the tip is shaped to conform to the surface configuration of the tip so that the liquid flows pass the tip in a laminar nonturbulent fashion through an orifice of reduced cross-section. The constriction is so dimensioned as to provide a high resistance path. A chamber is disposed downstream of the constriction and is of larger cross-section than the constriction. A discharged electrode is disposed in the chamber and is separated from the injection electrode by the chamber and the constriction. The injection and discharge electrodes are coupled to a high voltage generator to maintain an electric potential between the electrodes on the order of kilovolts.
