Abstract
Abstract Apparatus for dispersing liquids, comprises a casing which houses a reservoir for the liquid to be dispersed. A plurality of nozzles communicate with the reservoir, in which the liquid is placed under pressure. Any of a variety of devices for initiating dispensing of the liquid can be provided. Among these are, in the case of an aerial bomb, an inertial mass that ruptures the nozzles to open them upon impact of the bomb, or a slow-burning charge the pressure of whose combustion gases is applied to the liquid, or a parachute whose pull moves parts of the apparatus relative to each other to open the nozzles. The nozzle can selectively dispense directly to the atmosphere, to form a spray, or dispense through filters to form an aerosol.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
Apparatus for dispersing liquids, comprising a casing, a reservoir inside the casing for the liquid to be dispersed, at least one dispersing nozzle for the liquid in communication with the reservoir, means to place the liquid in the reservoir under pressure to ensure its atomization by said at least one nozzle, means to initiate dispensing of the liquid through the nozzles, and direct outlets for the atomized liquid, means for closing said direct outlets, and means to direct the atomized liquid through filter means when said outlets are closed, thereby to produce an aerosol.
Claim 2
Dependent Claim
94 words
Apparatus for dispersing liquids, comprising a casing, a reservoir inside the casing for the liquid to be dispersed, at least one dispersing nozzle for the liquid in communication with the reservoir, means to place the liquid in the reservoir under pressure to ensure its atomization by said at least one nozzle, means to initiate dispensing of the liquid through the nozzles, and direct outlets for the atomized liquid, means for closing said direct outlets, and means to direct the atomized liquid through filter means when said outlets are closed, thereby to produce an aerosol.
Claim 3
Dependent Claim
28 words
Apparatus as claimed in claim 1, in which said means for closing said outlets comprises a rotatable sleeve having openings therein adapted to register selectively with said outlets.
Claim 4
Dependent Claim
101 words
Apparatus for dispersing liquids, comprising a casing, a reservoir inside the casing for the liquid to be dispersed, at least one dispersing nozzle for the liquid in communication with the reservoir, means to place the liquid in the reservoir under pressure to ensure its atomization by said at least one nozzle, and means to initiate dispensing of the liquid through the nozzles, said means for initiating dispensing of the liquid comprising means for selectively opening said at least one nozzle, said opening means comprising an inertial mass adapted to break open the ends of the nozzles upon impact of the device.
Claim 5
Dependent Claim
101 words
Apparatus for dispersing liquids, comprising a casing, a reservoir inside the casing for the liquid to be dispersed, at least one dispersing nozzle for the liquid in communication with the reservoir, means to place the liquid in the reservoir under pressure to ensure its atomization by said at least one nozzle, and means to initiate dispensing of the liquid through the nozzles, said means for initiating dispensing of the liquid comprising means for selectively opening said at least one nozzle, said opening means comprising an inertial mass adapted to break open the ends of the nozzles upon impact of the device.
Claim 6
Dependent Claim
25 words
Apparatus as claimed in claim 3, and elastic means for returning said inertial mass to an upper position out of the path of the nozzles.
Claim 7
Dependent Claim
111 words
Apparatus for dispersing liquids, comprising a casing, a reservoir inside the casing for the liquid to be dispersed, at least one dispersing nozzle for the liquid in communication with the reservoir, means to place the liquid in the reservoir under pressure to ensure its atomization by said at least one nozzle, means to initiate dispensing of the liquid through the nozzles, said means for initiating dispensing of the liquid comprising means for selectively opening said at least one nozzle, and means to slow the descent of the apparatus through the air, said initiating means comprising means responsive to the pull of said slowing means, to open said at least one nozzle.
Claim 8
Dependent Claim
111 words
Apparatus for dispersing liquids, comprising a casing, a reservoir inside the casing for the liquid to be dispersed, at least one dispersing nozzle for the liquid in communication with the reservoir, means to place the liquid in the reservoir under pressure to ensure its atomization by said at least one nozzle, means to initiate dispensing of the liquid through the nozzles, said means for initiating dispensing of the liquid comprising means for selectively opening said at least one nozzle, and means to slow the descent of the apparatus through the air, said initiating means comprising means responsive to the pull of said slowing means, to open said at least one nozzle.
Claim 9
Dependent Claim
25 words
Apparatus as claimed in claim 5, and means to retain said responsive means in the position to which it is pulled by said slowing means.
