Abstract

748,950. Electronic counting apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 7, 1953 [April 8, 1952; Sept. 19, 1952; Feb. 17, 1953], Nos. 9595/53, 9596/53 and 9597/53. Divided out of 748,761. Drawings to Specification. Class 106 (1). A circuit comprises a cold-cathode scaling tube with means to cause a discharge in the tube to move to a main cathode substantially coincidently with the leading edge of a pulse which is derived to drive the discharge to that main cathode. The detailed description is substantially the same as that of Specification 748,761 which is referred to.
