Title (EN) COMPOSITION HAVING REGULATED OCCURENCE OF OPACITY AND CLARITY AT SELECTED TEMPERATURES AND METHOD OF MAKING THE SAME AND ALSO USE OF THE COMPOSITION
(FR) COMPOSITION PRESENTANT DES ETATS COMMANDES D"OPACITE ET DE TRANSPARENCE A DES TEMPERATURES SELECTIONNEES, SON PROCEDE DE PREPARATION ET UTILISATION DE CETTE COMPOSITION
Abstract:
(EN) A composition having regulated occurrence of opacity and clarity at selected temperatures; method of making and using such a composition to create a temperature-indicating device by filling the composition in a suitable container of transparent material and having a background in the form of a colour, a letter or a number i.e., in order to be able to visually interpret the difference between opacity and clarity. A reversible indicating device is made which can show if the upper or lower limits of a pre-set temperature interval has been exceeded or fallen below.
(FR) Composition présentant des états commandés d"opacité et de transparence à des températures sélectionnées; procédé de production etd"utilisation d"une telle composition pour créer un dispositif indiquant la température, en remplissant de cette composition un récipient approprié en matériau transparent et possédant un fond sous forme d"une couleur, d"une lettre ou un numéro, permettant d"interpréter visuellement la différence entre l"opacité et la transparence. On obtient un dispositif indicateur réversible qui peut montrer si les limites supérieures ou inférieures d"un intervalle prédéterminé de température ont été dépassées dans les deux sens.
