Abstract

A vehicle carried system for camouflage with foam includes a plant for generating water-based foam. The foam generating plant includes a reservoir for foaming liquid or a water tank with a reservoir for a foaming agent, which are connected to produce foaming liquid. The foaming liquid is pumped, or delivered in another way, under pressure to the foam generator for generating camouflage to be applied to the ground or to be filled into containers. Containers and free foam are preferably colored to give the protected object a good visual camouflage.

Claims

1. A vehicle carried system for camouflage with foam comprising:

a foam generating plant;

a foaming agent and water;

foam generators, and pumps associated with said foam generators;

containers formed of bags, preferably of cotton, colored to give a visual camouflage when moist and containing threads connected to the walls of said bags for modifying shape of said bags;

wherein said containers are attached to and carried by said foam generators, said containers having a shape which can be adapted by the adjustment of said threads in said bags to a particular position on a vehicle, said containers being filled with said foam by said pumps from said generators thereby moistening said bags to produce said visual camouflage.

2. A system for automatically applying a colored foam to ground comprising:

color control means including photometers to generate signals and a computer;

a movable prism or movable mirror;

a foam generating plant for generating colored foam from a foam agent having a color and water;

a plurality of reservoirs, each reservoir containing different foam coloring agents;

a plurality of pumps, each of which is associated with said reservoirs, wherein said mirror or prism directs the ambient light and colors of surrounding areas toward said photometers, said photometers thereby generating signals related to colors of said surrounding areas which signals are fed to said computers, said computer thereafter comparing said signals to said color of said foaming agent and controlling said pumps to add said coloring agents to said foaming agent so that said colored foam coincides with said ambient light and colors of said surrounding areas;

said surrounding areas including the ground and any foam generated from said foam generators.

3. A system according to claim 2, wherein said color control means includes photometers for sensing white, blue and red colors.

4. A system according to claim 2 or 3, wherein said computer controls pumps of separate reservoirs for yellow, blue, red and black coloring agents of said foam generating plant.

5. A system according to claim 4, wherein said pumps are driven by electric motors controlled by the computer.
