CPC Definition - Subclass F17B
This place covers:
Gas-holders for the storage of compressed, eventually liquefied or solidified gas, with large volume, and whose volume capacity can be changed by special means. Storage of gas is the only purpose of gas-holders.
The fluid contained in the gas-holders according to this subclass should be a gas. It is stored in a gaseous, mostly compressed, or in a liquefied or solidified state of matter in the pressure vessel.
Large vessels that contain other substances than gases are classified in B65D 88/00.
Attention is drawn to the following places, which may be of interest for search:
Large vessels not containing gas | |
Storing fluids in natural or artificial cavities or chambers in the earth | |
Pressure vessels containing gas |
In this place, the following terms or expressions are used with the meaning indicated:
Gas | Substance that is in gaseous state of matter at normal conditions (atmospheric pressure and normal ambient temperature). Substances that are in a gaseous state of matter but would not be gaseous at normal conditions are not considered in this subclass. Gas can be put in liquid (liquefied gas), or solidified state of matter, for storage. |
