Abstract: Two processes and apparatus for chromatographically separating components of a volatilizable mixture on a continuous basis are described herein as specific examples of the continuous preparative chromotographic separation of unwanted volatile species from volatile product by passage through a continuous fibrous textile solid. The volatilized mixture is fed by means of a flowing carrier gas through a column or conduit containing continuous polymeric solid therein such as a fibrous textile solid like yarn wherein one unwanted component of the mixture is significantly retarded in its passage by adsorption processes as compared to the other components of the mixture. The retarded component is that which one wishes to remove from the mixture. The desired product is gathered at the outlet of the conduit. The polymeric solid separating medium is regenerated by removal of the adsorbed component in either of two ways.

Abstract: A calorimeter which measures a naturally induced flow of incoming air in a horizontal entry duct (air-inlet chamber) and through a horizontal elbow duct to an upright straight flue used as a combustion chamber, the measuring system consisting of a thermistor version of a hot-wire anemometer, a bridge circuit with a matched thermistor, and a strip chart recorder, the calorimeter utilizing convective air flow to make practical a method for directly, continuously, and quantitatively measuring, over the entire period of combustion from ignition to extinguishment, the heat emitted by a burning test material positioned in the upright vertical flue, thus providing a realistic, sensitive, and accurate method for monitoring quantities such as the total heat emitted per unit mass of sample, the total heat emitted per unit mass of volatilized portion, the maximum emitted energy flux, and the average burning acceleration, the apparatus being particularly useful for continuously evaluating burning behavior, particularly o
