DEFINITION

Classification: 109/29

(under subclass 23) Devices wherein means is provided for releasing, generating and/or distributing gas, smoke, vapors and/or liquids either manually, automatically upon attack, or automatically in case of fire. The fluent material is normally, but not necessarily, toxic, noncombustible, or incapacitating and may normally, but not necessarily, be used to repel attacks and/or put out, prevent, or impede the action of a fire. This subclass includes devices relating to jails, where the purposes of this subclass are also present.
