Abstract
Abstract A gas containing carbon dioxide is passed over a bed of carbon dioxide absorbent which contains an elongated temperature sensor which measures the peak temperature along its length and provides a temperature signal. A second sensor which measures the temperature of the gas prior to its reaction with the absorbent provides a second temperature signal. The signals are combined to get a resultant which is indicative of the carbon dioxide present in the gas.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
Apparatus for removing and monitoring a particular gas of a gas mixture containing said gas, comprising: a. a container having an input for receiving said gas mixture, and an output; b. said container having therein a bed of reactant material of the type which will absorb said gas in a reaction which liberates a certain quantity of heat dependent upon the quantity of said gas absorbed; c. first temperature sensor means disposed along the length of said bed of reactant material and operable to provide a first output signal indicative of the peak temperature along the said length; and d. second temperature sensor means for providing a second output signal indicative of the temperature of said gas mixture prior to said reaction; and e. means for providing an indication of the difference between said first and second output signals.
Claim 2
Dependent Claim
139 words
Apparatus for removing and monitoring a particular gas of a gas mixture containing said gas, comprising: a. a container having an input for receiving said gas mixture, and an output; b. said container having therein a bed of reactant material of the type which will absorb said gas in a reaction which liberates a certain quantity of heat dependent upon the quantity of said gas absorbed; c. first temperature sensor means disposed along the length of said bed of reactant material and operable to provide a first output signal indicative of the peak temperature along the said length; and d. second temperature sensor means for providing a second output signal indicative of the temperature of said gas mixture prior to said reaction; and e. means for providing an indication of the difference between said first and second output signals.
Claim 3
Dependent Claim
24 words
Apparatus according to claim 1 wherein: a. said first temperature sensor means is surrounded by said reactant material and is substantially centrally aligneD therein.
Claim 4
Dependent Claim
29 words
Apparatus according to claim 1 which additionally includes: a. means for providing an indication of the location of peak temperature along the length of said first temperature sensor means.
