Abstract
107,811. Webster, H. R. July 12, 1916. Indicating.-In a gas-analysis apparatus wherein a porous vessel A contains a chemical absorbent for one constituent of the gas, and the difference in pressure between the inside and outside of the vessel when surrounded by the gas is used to indicate the amount of this constituent, the porous vessel is closed by a flexible diaphragm T<1>, the movements of which are transferred to a pointer X<1> on a dial X by a rod X<7> connected to the diaphragm and pressed against it by a spiral spring T<4> acting upon a lever X<6> attached to a pinion X<4> gearing with a pinion X<3> on the axle of the pointer. The indicating-device is carried by a screw X<8> adapted to be turned by a handwheel Y to move it up or down to adjust the pointer to zero.
