Abstract: An atomized cloud of droplets having an electric charge is generated wherein different discrete parts of the cloud are formed from different liquids. The discrete part of the cloud which has an active ingredient, such as a chemical insecticide or herbicide, is contained such as by enveloping it or directing it in a particular direction by a further discrete part of the cloud that includes an inert liquid such as water. The spraying apparatus comprises a plurality of nozzles positioned in a high velocity air stream to disperse liquid and generate an atomized cloud of the liquid. The nozzles are grouped into at least two sets, each set being arranged and positioned to generate a discrete part of the cloud. An electric charge is placed on the droplets as they are emitted. Each set of nozzles further include a liquid reservoir connected to the nozzles. Each reservoir is to contain a different liquid whether it be an inert liquid or different concentrations of an active liquid.

Abstract: A control device for metering fluid flow from a remote location is shown in conjunction with an insecticide spraying apparatus. The spraying apparatus includes a compressed air source feeding pressurized air to a nozzle for mixing with a liquid and discharge to atmosphere. A metering pump feeds the liquid to the nozzle in response to a digitized input signal received from a remote control device. A digitized feedback signal including a number of pulses per unit time from the metering pump to the remote control device indicates the rate of flow of the liquid through the metering pump. The remote control device compares the digitized feedback signal with a control voltage to generate the digitized input signal which is a pulse-width modulated signal, which digitized input signal maintains the flow rate of the liquid. A pressure switch connected to the nozzle insures a predetermined pressure therein before the metering pump will begin feeding liquid to the nozzle.
