Abstract
Abstract Improved performance of known techniques of spraying liquids to form extremely dense liquid sprays or aerosols can be obtained by pre-saturation of the carrier gas at a given location before final introduction of the product to be aerosolized into the spraying system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A method of spraying comprising the steps of providing a spray chamber, providing a first liquid atomizing means in said chamber, providing at least one additional liquid atomizing device in said chamber in series with the first atomizing device, introducing carrier gas into said chamber so as to pass over the series oriented atomizing devices while confined within said chamber, simultaneously operating said atomizing devices to produce atomized liquid particles whereby the atomized particles from said first device are at least partially evaporated into the carrier gas prior to its passage over said additional atomizing devices and thereafter discharging said particle-laden carrier gas from said chamber.
Claim 2
Independent Claim
106 words
A method of spraying comprising the steps of providing a spray chamber, providing a first liquid atomizing means in said chamber, providing at least one additional liquid atomizing device in said chamber in series with the first atomizing device, introducing carrier gas into said chamber so as to pass over the series oriented atomizing devices while confined within said chamber, simultaneously operating said atomizing devices to produce atomized liquid particles whereby the atomized particles from said first device are at least partially evaporated into the carrier gas prior to its passage over said additional atomizing devices and thereafter discharging said particle-laden carrier gas from said chamber.
Claim 3
Dependent Claim
39 words
The method of spraying defined in claim 1 wherein there is provided at least a pair of pneumatic atomizing devices and the gas aspirated through said chamber is provided by the venturi effect generated by said pneumatic atomizing devices.
Claim 4
Dependent Claim
36 words
The method of spraying as defined in claim 1 wherein there is provided at least a pair of ultrasonic atomizing devices and said step of providing aspirating gas is effected by a separate gas moving device.
Claim 5
Dependent Claim
40 words
The method of spraying as defined in claim 1 including the further step of impacting the atomized spray from at least one of said atomizing devices to further reduce particle size of the substance being conveyed by the carrier gas.
Claim 6
Independent Claim
124 words
A method of producing high density liquid sprays of particles on the order of 10 microns or less comprising the steps of providing a moving stream of a carrier vehicle within a chamber, first introducing the liquid substance being sprayed into said carrier vehicle in atomized particle form whereby a portion of the particles are absorbed by said carrier vehicle while in said chamber and thereafter introducing additional amounts of the substance being aerosolized into the carrier vehicle in liquid particle form within said chamber, whereby the majority of particles last introduced into the carrier vehicle are retained and carried thereby to a point of use in liquid particle form and discharging said particle-laden carrier vehicle from said chamber to the point of use.
Claim 7
Independent Claim
124 words
A method of producing high density liquid sprays of particles on the order of 10 microns or less comprising the steps of providing a moving stream of a carrier vehicle within a chamber, first introducing the liquid substance being sprayed into said carrier vehicle in atomized particle form whereby a portion of the particles are absorbed by said carrier vehicle while in said chamber and thereafter introducing additional amounts of the substance being aerosolized into the carrier vehicle in liquid particle form within said chamber, whereby the majority of particles last introduced into the carrier vehicle are retained and carried thereby to a point of use in liquid particle form and discharging said particle-laden carrier vehicle from said chamber to the point of use.
