Gas is discharged from a retort-bench stand-pipeinto a gas container, which is included in a closedsystem in wliich liquid is circulated in contactwith the gas to cool it. A thermostat is placedin the path of the gas for regulating the flow ofthe liquid according to the temperature of the gas. —B. N, Gas-irashcr. T. JIcDonald, Youngstowii. Pat. .1,, Jan. 11, 1916.

The gas is burnt in successive stages ; after theflist combustion of the gas and air mixture, thecombustion gases and unburned jiortions arecollected, heated, and projected against a surfaceto secure their better iiiteriiiixtuii, and a secondcombustion is obtained in this way. without theaddition of more air.
