1,003,045. Utilizing energy of radiations. YARDNEY INTERNATIONAL CORPORATION. July 12, 1962 [July 12, 1961], No. 26861/62. Heading G6P. [Also in Division H2] A nuclear cell comprises an evacuated sealed glass ampoule 5, containing an inert gas such as argon or krypton, provided at one end with an electrically conductive coating 7 or alternatively a plate containing a radioactive material such as promethium, 147, constituting the anode. The cathode 9 may be of any electrically conductive material such as copper, nickel, aluminium or brass. Leads 11 and 13 are sealed into the ampoule. In operation beta emission from the radioactive isotope ionizes the gas and causes a cement to flow through an external battery 1. The anode and cathode may be alternatively separated by solid dielectric. Specifications 682,164, 698,405 and U.S.A. Specification 2,812,376 are referred to. |
