CPC Definition - Subclass C06D
This place covers:
Chemical aspects of generating smoke or mist.
Generation of pressure gas, e.g. for blasting cartridges, starting cartridges, rockets.
Compositions for gas-attacks ,e.g. toxic, irratating or debilitating gas-compositions..
This place does not cover:
Devices for generating heat, smoke, or fog in gardens, orchards, or forests, e.g. to prevent damage by frost | |
Compositions used as biocides, pest repellants or attractants, or plant growth regulators | |
E.g. |
Attention is drawn to the following places, which may be of interest for search:
Apparatus for generating gases | |
Inflatable occupant restraints or confinements characterized by the inflation source or means to control inflation fluid flow | |
Explosive compositions containing an oxidizer, fuels for rocket engines intended for reaction with an oxidant other than air | |
Fuels, e.g. natural or synthetic natural gas | |
Rocket-engine plants, i.e. plants carrying both fuel and oxidant therefor; Control thereof | |
Non chemical aspects of generating combustion products of high pressure of high velocity | |
Smoke-pot projectors | |
Smoke-producing projectiles, missiles or mines |
This place covers:
Generation of smoke or mist, e.g.
- classic smokes are based on highly hygroscopic salts being acids and forming a water droplet fog with air humidity
- Demisting compositions.
- Weather modifying compositions such as making rain.
- with expanded graphite particles
- by combustion of pyrotechnic compositions comprising a chlorine donor (e.g. potassium chloride, sodium chloride, chlorinated rubber, condensed halogenated carbon compound) that will generate upon combustion abundants amounts of sublimable metal chlorides wich produce smoke
- by combustion of pyrothechnic composition with sublimation/vaporization of an organic dye
- by combustion of pyrotechnic composition comprising zinc oxide, ammonium cloride and polyvinyl chloride
- by combustion of pyrotechnic smoke generating composition comprising red phosphorous
- by incomplete combustion of aromatic compounds
This place does not cover:
Compositions used as biocides, pest repellants or attractants, or plant growth regulators |
Attention is drawn to the following places, which may be of interest for search:
Compositions containing particulate metal, alloy, boron, silicon, selenium or tellurium with at least one oxygen supplying material which is either a metal oxide or a salt, organic or inorganic, capable of yielding a metal oxide | |
Compositions containing free phosphorus or a binary compound of phosphorus, except with oxygen |
In patent documents, the following words/expressions are often used as synonyms:
- "repellent" and "repellant"
This place covers:
Generation of pressure gas
Explosive compositions containing an oxidizer, fuels for rocket engines intended for reaction with an oxidant other than air are classified in C06B.
The compositions in C06B are mainly classified according to their chemical composition. In C06B 47/00 monopropellants and bipropellants are classified according to their composition.
This place covers:
CO2 - blasting.
This place covers:
Catalysts for the auto-decomposition
For example decomposition of hydrogen peroxide, hydrazine.
Attention is drawn to the following places, which may be of interest for search:
Compositions in which the components are separately stored until the moment of burning or explosion and one component contains hydrazine or a hydrazine derivative |
