Abstract
Abstract A gas security system having an interchangeable self-contained tank arranged for connection to a bottle containing a compressed gas. The latter serves as a propellant for a noxious charge provided in the tank. A normally closed electric valve is arranged in a pipe connecting the bottle and tank, while an actuating circuit associated with the valve is arranged for opening the valve on detection of the presence of a predetermined condition in areas with which the security system is related. Noxious gas is formed by interaction of the propellant and noxious charge, and is passed throughout a building, and the like, by a distributing system extending from the tank.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
253 words
A gas security system, comprising, in combination: a. a noxious charge; b. first container means for holding the noxious charge; c. a propellant gas; d. second container means for holding the propellant gas under pressure, the second container means including a manuallyactuatable shut-off valve connected to the pipe means; e. pipe means for connecting the second container means to the first container means; f. normally-closed valve means arranged in the pipe means for normally blocking same, the valve means including an electrically actuated solenoid valve, the pipe means including an adjustable pressure regulator arranged between the shut-off valve and the valve means; g. actuating means connected to the valve means for opening the valve means on the presence of a predetermined condition and passing gas to the noxious charge to intersect with the charge and form a noxious gas, the actuating means including a normally open relay connected to a source of power and to the valve, and a normally open switch connected to the relay for closing samd when the switch is closed by the presence of an unauthorized person in an associated building; h. a signal lamp electrically connected to the relay in parallel with the solenoid valve; and i. a distributing means connected to the first container means for receiving a noxious gas from the first container means and dispensing the gas into a predetermined space in the building, the distributing means including a manifold provided with a plurality of outlets, one of the outlets terminating in a gas whistle.

Claim 3
Dependent Claim
104 words
A gas security method for distributing a noxious gas into a predetermined space in a building, comprising the steps of: a. providing a noxious charge in a first container and a propellant gas under pressure in a second container; b. detecting presence of an unauthorized person in a building being guarded; c. passing gas from the first container to the second container only when an unauthorized person is detected in the associated building by step (b); d. forming a noxious gas by interaction of the propellant gas and noxious charge whenever step (c) is performed; and e. distributing the noxious gas about the building.
Claim 4
Dependent Claim
104 words
A gas security method for distributing a noxious gas into a predetermined space in a building, comprising the steps of: a. providing a noxious charge in a first container and a propellant gas under pressure in a second container; b. detecting presence of an unauthorized person in a building being guarded; c. passing gas from the first container to the second container only when an unauthorized person is detected in the associated building by step (b); d. forming a noxious gas by interaction of the propellant gas and noxious charge whenever step (c) is performed; and e. distributing the noxious gas about the building.
Claim 5
Dependent Claim
33 words
A method as set forth in claim 2, wherein the distributing step (e) includes the step of ejecting the noxious gas through a gas whistle and sounding a warning to the unauthorized person.
Claim 6
Dependent Claim
28 words
A method as set forth in claim 3, further including the step of energizing a lamp when an unauthorized person is detected in the building by step (b).
Claim 7
Dependent Claim
28 words
A method as set forth in claim 2, further including the step of energizing a lamp when an unauthorized person is detected in the building by step (b).
