| abstract | 936,065. Temperature indicators. MINNEAPOLIS-HONEYWELL REGULATOR CO. July 13, 1962 [July 13, 1961], No. 27063/62. Drawings to Specification. Class 97 (3). A temperature history indicator comprises a sealed container having therein at least two separate masses of gel, the gel masses retaining therein respectively, interstitial liquids of markedly different colours which will mingle upon thawing following destruction of the gel structures by freezing. The gel masses may consist of 6-8% by volume of sodium silicate, 2% by volume of concentrated hydrochloric acid and the balance an aqueous solution containing a dye. Alcohols, glycols and salts may be used to depress the freezing point of the mixture and silver iodide may be added to provide nuclei for ice crystallization so that at the appropriate temperature the aqueous solution freezes and does not supercool. Blue and yellow dyes may be used so that after freezing and subsequent thawing there is a green coloration. To indicate whether or not a second lower temperature has been reached on freezing, three gel masses may be provided, two of them freezing at a first temperature and the third at a lower temperature. A fixed or movable divider may be provided between two gel masses. |
