Ericsson Rev. 37(1960): 4, pp. 102—113.This article sums up the present situation in different fields of telecommunicationsin the light of the developments in telephony during the pastdecade, going on therefrom to what may be expected during the sixtieson the basis of the advances in fundamental sciences and in technology.The article is adapted from a lecture given to the Swedish National Associationof Electrical Engineers on September 9, 1960.UDC 621.395.44:62.002.2LME 102, 84ERIKSEN, E J & AXELSON, K: A New Method of Construction for TransmissionEquipment. I. Background to Design; II. Mechanical Design.Ericsson Rev. 37(1960): 4, pp. 114—126.The article and the subsequent one in this series will deal with L MEricsson's new method of construction for transmission equipment. Ashort survey is given in this introductory article of the crucial factors inthe decision to carry out a new design. Primarily, the desire has been toobtain an efficient method of construction for the new transistorizedgroup and supergroup equipment. Furthermore, the article describes thegeneral mechanical features of the equipment: design details, however,are only gone into where these are of importance for the mechanical orelectrical functioning or for maintenance.UDC 654.937.2:681.177LME 865SODERBERG, L: The Centralograph Used for Production Control ofPunched Card Machines. Ericsson Rev. 37(1960): 4, pp. 127—132.For many years the Centralograph has been employed for supervisingproduction in different branches of industry such as ironworks, textile factories,etc., where it has also been a planning aid. More recently, the Centralographhas been used in Punched Card Departments to ensure improvedutilization of the often expensive machines. In the autumn of 1958, SwedishEsso installed a Centralograph system. In this article the supervisor of thePunched Card Department describes the experience gained.
