摘要：292,607. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System Aktiebolag). June 23, 1927, [Convention date]. Gas analysis; diffusion apparatus for gases. - In an apparatus for indicating the composition of a gas wherein the gas is diffused through a porous member into a measuring chamber, the gas so diffused is - exposed to the action of an absorption medium having a constant absorption .capacity such as a liquid of constant composition passing in con. tinuous flow. The apparatus shown comprises a diffusion vessel formed of three discs 5- - 7 connected together in a fluid-tight manner and having formed therein a cavity 8 communicating on one side through porous partitions 10, 18 with cavities 9, 17, and on the other side through a porous partition 27 with a cavity 30. Absorptive liquid such as a solution of caustic potash is caused to flow continuously from a Marriott's bottle 3 into the cavity 9 through the partition 10, thence in a thin film over the surface of the cavity 8 and out through the partition 18 and cavity 17 to a receptacle 4. The gas to be heated is admitted to the cavity 30 through an inlet 32 and passes out through an outlet 34. The reduction of pressure caused by the absorption of constituents from the gas passing through the partition 27 into the cavity 8 is measured by the manometer device 39, 41. Ventilating salves 16, 22 are provided, for the cavities 9, 17 respectively, for the removal of air.
