New Radio Terms

DEFINED IN USS.A. a RECEIVING SET NOMENCLATURE To improve advertising and merchandising of radio receiving sets, and to.aid the public in its purchases by official definitions of "electric," "socket powered," and other receiving ‘sets, the United States Radio Manufacturers’ Association, in co-operation with other radio trades associations, . is presenting a radio receiver nomenclature. The definitions of different types of receiving sets are designed as a guide not only to the 3800 principal radio manufacturers belonging to the R.M.A., but also to advertising and business interests, as well as the public. Use of the official receiving set definitions in manufacturers’ advertising, and also in that of jobbers and dealers handling R.M.A. products, will be requested. Advertising and merchandising agencies, including better business bureaus, also will be advised of the definitions agreed upon, designed to avoid misinformation to the public of the different varieties of receiving sets. Expect General Adopton. The receiving set definitions -were developed by the R.M.A. engineering division, of which H. B. Richmond, of Cambridge, Mass., is director, with the assistance of technical committees of other organisations. The definitions were adopted and approved wunani--mously by the R.M.A. board of directors at their meeting at Buffalo, and are expected to receive the official approval of other yadio trades associations, so that the definitions may be generally adopted in manufacturers’ literature and advertising during the coming season. In an effort to improve merchandising practices and keep the radio buying public from being misled in the use of terms applied to receiving sets, the R.M.A. engineering division and the board of directors recently adopted definitions for "socket powered," and other radio operation. These were designed more as engineering definitions rather than for guidance of the public and use in the merchandising of radio, The new and official radio merchandising definitions are as follow :- BATTERY OPERATED SET-A radio receiver designed to operate from primary cells or storage batteries, shall be known as a "Battery Operated Set." SOCKET-POWERED SET-A radio receiver of the "Battery Operated" type, when connected to a power unit operating from the electric light line, supplying both filament and plate potentials to the tubes of the receiver, ae be known as a "Socket-Powered se td *

ELECTRIC SET-A radio receiver overating from the electric light line, without using batteries, shall be known as an "Hlectrie Set." A. C. TUBE ELECTRIC SET-A radio receiver employing tubes which obtain their filament or heater currents from an alternating current electric light line without the use of rectifying devices, and with a built-in tube rectifier for the plate and grid biasing potentials, shall be known as an "A C, Tube Dlectric Set." D. C. TUBE ELECTRIC SET-A. radio receiver employing tubes which obtain their filament or heater currents from a direct current electric light line without the use of rectifying devices, and with a built-in power plant for the plate and grid biasing potentials, shall be known as a "D. C. Tube Electric Set."
