Abstract

204,499. Schr÷der, E. Sept. 5, 1922. Current detectors; indicating h e a t by change of colours; temperature errors, compensating for. - In a device for showing the temperature conditions of current conductors in electric machines, and of the kind comprising an indicator adapted to change its colour with change of temperature, the indicator is surrounded by a heatinsulator adapted to vary the rate of heat radiation from the indicator. The device comprises a contact plug the pins a of which are connected by a plate b adapted to change colour with change of temperature. The plate is enclosed in a casing e provided with a glass cover d. The casing is perforated with holes f, and a correspondingly perforated annulus g slidably mounted theron, closes more or less of the holes, and so regulates the quantity of heat flowing through the casing from the plate b. The plate may have a cross or other design in iodide of mercury on a red ground at normal temperature, the cross becoming visible with change of colour to yellow; or the plate may be prepared with other substances, such as iron, cobalt, or nickel compounds, and may indicate several temperatures, for example by having both the ground and the design changeable in colour.
