Abstract

508,677. Electric signalling systems. PIZZALA, J., (trading as SOMALVICO & CO., LONDON). Nov. 14, 1938, No. 31843/37. Drawings to Specification. [Class 40 (i)] In an electrically-indicating thermometer, two resistance wires are arranged lengthwise of the bore of a liquid-in-glass type thermometer, or if the bore is small, one wire only is used ; the second wire passing through the wall of the bore above the bulb to make contact with the liquid. Specifications 5428/95, 23461/06, [both in Class 97], and 27678/09, [Class 97 (iii)], are referred to.
