Abstract
135,157. Brown, S. G. Aug. 13, 1918. Non - contact - making relays. - A relay comprises a variable resistance formed bv separating two portions of an electrolyte by an insulating partition containing a restricted passage adapted to be varied by the movements of a moving coil. The resistance may be of any of the forms described in Specification 134,865. A pair of vanes 13, 14 carried by an arm on the spindle 12 of a moving-coil galvanometer moves in front of small apertures 9, 10 in a diaphragm 10 which separates the electrolyte in two compartments 1, 2 from that in a third compartment 3. Electrodes 6, 7, 8 are arranged in these compartments. Movement of the vanes 13, 14 varies the ratio between the resistances of the apertures 9, 10 and thus causes energization of a coil 11 connected between the electrode 8 and. the middle point of a battery B. According to the Provisional Specification, a vertical strip of material may be moved transversely to vary tha size of the opening in the diaphragm.
