Zusammenfassung:	A METHOD OF IMPROVING THE SPRAYING OF LIQUID DROPLETS FROM A SPRAY DEVICE ONTO A SURFACE WHICH METHOD COMPRISES IMPARTING A UNIPOLAR CHARGE TO THE SAID LIQUID DROPLETS BY DOUBLE LAYER CHARGING DURING THE SPRAYING OF THE LIQUID DROPLETS FROM THE SPRAY DEVICE, THE UNIPOLAR CHARGE BEING AT A LEVEL SUCH THAT THE SAID DROPLETS HAVE A CHARGE TO MASS RATIO OF AT LEAST +/- 1X10-4 C/KG, WHEREBY THE CHARGED DROPLETS OF THE LIQUID ARE MUTUALLY REPELLED THEREBY INCREASING THE SPREAD OF THE DROPLETS FROM A CENTRAL LINE EXTENDING FROM THE HEAD OF THE SPRAY DEVICE AND AVODING COALESCENCE OF THE DROPLETS, THUS PROVIDING A MORE EVEN COVERAGE OF THE SURFACE WHICH IS TO BE SPRAYED.IN PARTICULAR, THE METHOD ENABLES LIQUID DROPLETS TO BE SPRAYED ONTO A SURFACE WHICH IS OBSCURED BY AN OBJECT LOCATED BETWEEN THE SURFACE AND THE SPRAY DEVICE.
