Abstract

7587. Carolan, E. A., [General Electric Co.]. April 1. Quantity meters. - An electrolytic meter has one electrode carried by a float 7, which is graduated vertically to read against an indicator 21 on another float 23, the whole being enclosed by a glass receptacle 1 with a stopper 14. Mercury electrodes may be used in a solution of mercurous nitrate. The anode may be carried on an annular shelf or trough, connection with it being made by a wire passed through the stopper and coated with insulating-material 15 to protect the wire from the solution. The float 7 may be of glass, with a graduated neck 19, and a depending tube 6 carrying an open bulb 5, which contains the cathode. A wire sealed in the lower end of the tube 6 connects the cathode to some mercury in this tube; a connecting-wire 13, secured in the stopper, dips in the mercury in the tube 6. A wire 17 projects from the bulb 5 into mercury in a tube 18, to compensate for the varying displacement of mercury in the tube 6 by the wire 13, and to guide the float. The indicator 21 is a ring carried by arms on an annular float 23. The meter is shunted by a main resistance 10. Both electrodes may be movable, the second one being carried by the float 23.
