Abstract

The invention comprises an apparatus for maintaining liquid and dry chemicals safely separate in hermetically sealed containers and for rapidly mixing and agitating the chemicals in flight just prior to launch of the munition.

Claims

1. An apparatus comprising:

a container adapted to receive a first chemical;

a receptacle disposed within said container and adapted to receive a second chemical;

means for forcing said second chemical through the walls of said receptacle and rupturing the same;

structure interconnecting said container and receptacle and including a part with a reduced portion preventing said rotation;

means for rupturing said part at the reduced portion thereof for releasing said receptacle for rotation; and

means for imparting rotation to said receptacle.

2. The apparatus of claim 1, wherein said last-named means include gas-expandable means.

3. The apparatus of claim 2, wherein the walls of the receptacle are scored and rupture along predetermined lines for providing agitating means.

4. The apparatus of claim 3, wherein said gas-expandable means include a tubular member collapsed inwardly for providing pockets which receive said second chemical.

5. An apparatus for rapidly mixing and agitating chemicals in a sealed container comprising:

an elongated container for receiving a first chemical;

a tubular member disposed within said container and having one end thereof closed and journaled for rotation;

structure connecting the other end of said tubular member to said container in sealed relation, said structure including a part journaling said other end for rotation and a part with a reduced portion preventing such rotation;

gas-expandable means within said tubular member having a collapsed form providing pockets for receiving a second chemical;

gas-forming means connected to said gas-expandable means; and

means journaling said gas-forming means for rotation and having an explosive charge at said reduced portion for rupturing the same and releasing said tubular member for rotation.

6. The apparatus of claim 5, wherein said tubular member includes a grid-like structure having longitudinally extending strips and circumferential bands, the walls of said tubular member being scored along lines between said strips and adjacent said bands, expansion of said gas-expandable means serving to force said second chemical through the walls of said tubular member and through the spaces between the strips and bands of said grid-like structure for rupturing the walls of the tubular member along the scored lines and forming agitating blades.

7. The apparatus of claim 6, further comprising means for imparting rotation to said tubular member;

said last-named means, said gas-forming means and the explosion of said charge all being initiated simultaneously for forcing said second chemical into the first chemical and mixing and agitating the same.
