New methods of radio production

Abstract

The paper deals with a new conception of designing electrical apparatus such as that employed in communication, embracing telegraphy, telephony, television and light-current electrical applications generally and provides an improved and more economical method of circuit manufacture.In order to give electronic apparatus, a form which lends itself to fully mechanized production methods, a principle has been evolved of treating a circuit, not as an assembly of component elements but as a “compound” whole. Deposited conducting materials and a preformed dielectric plate replace the chassis and the multitude of parts in their more familiar form.Unlike earlier methods, in which connecting paths between prefabricated components were formed by deposition, in the method described the plate is given a predetermined structural form which determines the electrical characteristics of the completed circuit. The insulated plate, apart from acting as the support, also serves as the coil former and the dielectric of fixed capacitors.The design conception is such that electronic circuits can be produced in final form by a fully automatic electronically controlled processing machine which is described as “E.C.M.E.”—the Electronic Circuit-Making Equipment.
