Abstract
Abstract Safety system to prevent fire or explosion in fuel transporting tank trucks. The tank portion is surrounded by a pressurized system which when broken, as by impact, the altered pressure in the system automatically starts fire foam generating equipment to produce fire foam which is automatically dispensed in the immediate area of the tank. In a preferred form the pressurized system comprises a jacket which completely encompasses the fuel carrying tank, and the space between the tank and the jacket is charged with a pressure of air or inert gas which is slightly higher than atmospheric pressure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
In a system for use with flammable material storage means, safety means adapted to be secured in proximity to said storage means and including a fluid system containing a fluid normally maintained at a certain pressure, dispensing means for storing a fire suppressing material separate from said fluid in said fluid system and operable for rapidly dispensing a substantial volume of said fire suppressing material into the external space surrounding said storage means and said fluid system, and pressure responsive means responsive to a predetermined change in pressure in said fluid system to initiate operation of said dispensing means to effect rapid dispensing of a substantial volume of said fire suppressing material into said external space.
Claim 2
Dependent Claim
116 words
In a system for use with flammable material storage means, safety means adapted to be secured in proximity to said storage means and including a fluid system containing a fluid normally maintained at a certain pressure, dispensing means for storing a fire suppressing material separate from said fluid in said fluid system and operable for rapidly dispensing a substantial volume of said fire suppressing material into the external space surrounding said storage means and said fluid system, and pressure responsive means responsive to a predetermined change in pressure in said fluid system to initiate operation of said dispensing means to effect rapid dispensing of a substantial volume of said fire suppressing material into said external space.
Claim 3
Dependent Claim
85 words
In a system for use with flammable material storage means, safety means adapted to be secured in proximity to said storage means and including a fluid system normally having a certain fluid pressure, dispensing means for dispensing a fire suppressing material, and pressure responsive means responsive to a change in pressure in said fluid system from said certain pressure for initiating operation of said dispensing means, said dispensing means being electrically activated, and said pressure responsive means including means for electrically activating said dispensing means.
Claim 4
Dependent Claim
85 words
In a system for use with flammable material storage means, safety means adapted to be secured in proximity to said storage means and including a fluid system normally having a certain fluid pressure, dispensing means for dispensing a fire suppressing material, and pressure responsive means responsive to a change in pressure in said fluid system from said certain pressure for initiating operation of said dispensing means, said dispensing means being electrically activated, and said pressure responsive means including means for electrically activating said dispensing means.
Claim 5
Dependent Claim
41 words
In a system as defined in claim 2, wherein said flammable material storage means is in the form of vehicle-carried tank means, battery means separate from the vehicle electrical system and arranged for supplying power for energization of said dispensing means.
Claim 6
Dependent Claim
133 words
In a system for use with flammable material storage means in the form of tank means containing a flammable fluid, safety means adapted to be secured in proximity to said storage means and including a fluid system normally having a certain fluid pressure, dispensing means for dispensing a fire suppressing material, and pressure responsive means responsive to a change in pressure in said fluid system from said certain pressure for initiating operation of said dispensing means, said fluid system including wall means adapted to form an outer jacket for cooperation with said tank means to form a fluid-containing enclosed space, said certain fluid pressure being substantially different from atmospheric pressure and said pressure responsive means being responsive to a change in fluid pressure toward atmospheric pressure caused by puncture of said wall means.
Claim 7
Dependent Claim
133 words
In a system for use with flammable material storage means in the form of tank means containing a flammable fluid, safety means adapted to be secured in proximity to said storage means and including a fluid system normally having a certain fluid pressure, dispensing means for dispensing a fire suppressing material, and pressure responsive means responsive to a change in pressure in said fluid system from said certain pressure for initiating operation of said dispensing means, said fluid system including wall means adapted to form an outer jacket for cooperation with said tank means to form a fluid-containing enclosed space, said certain fluid pressure being substantially different from atmospheric pressure and said pressure responsive means being responsive to a change in fluid pressure toward atmospheric pressure caused by puncture of said wall means.
Claim 8
Dependent Claim
17 words
In a system as defined in claim 4, said certain fluid pressure being greater than atmospheric pressure.
Claim 9
Dependent Claim
17 words
In a system as defined in claim 4, said certain fluid pressure being less than atmospheric pressure.
Claim 10
Dependent Claim
92 words
In a system for use with flammable material storage means, safety means adapted to be secured in proximity to said storage means and including a fluid system normally having a certain fluid pressure, dispensing means for dispensing the fire suppressing material, and pressure Responsive means responsive to a change in pressure in said fluid system from said certain pressure for initiating operation of said dispensing means, said dispensing means including conduit means for extending alongside said storage means and having a plurality of openings for flow of said fire suppressing material therefrom.
Claim 11
Dependent Claim
92 words
In a system for use with flammable material storage means, safety means adapted to be secured in proximity to said storage means and including a fluid system normally having a certain fluid pressure, dispensing means for dispensing the fire suppressing material, and pressure Responsive means responsive to a change in pressure in said fluid system from said certain pressure for initiating operation of said dispensing means, said dispensing means including conduit means for extending alongside said storage means and having a plurality of openings for flow of said fire suppressing material therefrom.
