LABELED ELECTROCHEMICAL CELL WITH BUILT-IN TESTER AND LABEL MANUFACTURING PROCESS Russian patent published in 2000 - IPC

FIELD: electrical engineering. SUBSTANCE: according to invention, label-tester combination has thermochromium substance which is in thermal contact with conductive material. Substructure having hardened conductive material and also thermochromium substance is formed on separable cloth and transferred from the latter to inner surface of base film subjected to heat deposition. Separating coat may be deposited on top of transferred conducting material. Paper sheet or plastic film with large port for air entrapping should be deposited on top of separating coat and leveled off above heat-inducing area of conductive material. Label-tester combination is placed on cell case by means of insulating paper or plastic film with port opening about cell case. Tester may be activated by pushing one or two areas on its surface thereby connecting conductive material to cell leads; this action heats up conductive material causing changes in appearance of thermochromium substance to indicate operating conditions of device. EFFECT: facilitated manufacture due to eliminating deformation and shrinkage of label. 19 cl, 17 dwg
