Abstract
Abstract Decontaminating an object such as a vehicle, is achieved by subjecting thebject to an elevated temperature for a time sufficient to achieve the desired temperature. The heat source is preferably a jet engine which is supported for universal movement. The temperature of the surface of the object under treatment is determined by sensing the infrared radiation emanating from the surface of the object. In response to the attainment of a predetermined level of infrared radiation, an electric control member is used to regulate the movement of said heat source. Thus heating is caused to be directed at selected regions of the object under treatment for the time period necessary to attain the desired temperature level.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A system for decontaminating a vehicle contaminated by contact with toxic substances by burning said substances off the surface of said vehicle, said system comprising: a. movable heating means for providing a universally movable source of high temperature heat for directing heat at a spot on said vehicle; b. infrared temperature detector means directed toward said spot on said vehicle currently being heated, responsive to infrared radiation therefrom for generating an output signal proportionate to the instantaneous temperature of said spot; c. transducer means, electrically connected to said detector means for activating controlling fluidic flow in response to attainment by the said spot of a predetermined temperature level; d. controlling means, fluidically connected to said transducer means for generating fluidic control signals to a means for moving said heating means to aim said heat to another spot; and e. said means for moving being fluidically coupled to said controlling means for causing said high temperature heat of said heating means to be moved to different spots on said vehicle for heating.
Claim 2
Independent Claim
171 words
A system for decontaminating a vehicle contaminated by contact with toxic substances by burning said substances off the surface of said vehicle, said system comprising: a. movable heating means for providing a universally movable source of high temperature heat for directing heat at a spot on said vehicle; b. infrared temperature detector means directed toward said spot on said vehicle currently being heated, responsive to infrared radiation therefrom for generating an output signal proportionate to the instantaneous temperature of said spot; c. transducer means, electrically connected to said detector means for activating controlling fluidic flow in response to attainment by the said spot of a predetermined temperature level; d. controlling means, fluidically connected to said transducer means for generating fluidic control signals to a means for moving said heating means to aim said heat to another spot; and e. said means for moving being fluidically coupled to said controlling means for causing said high temperature heat of said heating means to be moved to different spots on said vehicle for heating.
Claim 3
Dependent Claim
14 words
The decontamination unit of claim 1, wherein said heating means is a jet engine.
Claim 4
Dependent Claim
70 words
The decontamination unit of claim 1, further comprising hydraulic means for providing a source of pressurized hydraulic fluid and control valve means, wherein said transducer means causes said controlling means to be rendered operative in response to said transducer means by controlling the opening and closing of said control valve, thereby permitting hydraulic fluid communication between said controlling means, said source of pressurized hydraulic fluid and said means for moving.
Claim 5
Dependent Claim
15 words
The decontamination unit of claim 1 wherein said controlling means is a proportional flow controller.
Claim 6
Dependent Claim
12 words
The decontamination unit of claim 1 wherein said vehicle is an aircraft.
