Note(s) "Printed circuits" are understood as covering all kinds of mechanical constructions of circuits that consist of an insulating base or support carrying the conductor and are combined structurally with the conductor throughout their length, especially in a two-dimensional plane, the conductors of which are secured to the base in a non-dismountable manner, and also as covering the processes or apparatus for manufacturing such constructions, e.g. forming the circuit by mechanical or chemical treatment of a conductive foil, paste, or film on an insulating support. This sub-class is understood as covering combinations of a radio or television receiver with apparatus having a different main function. This sub-class is also understood as covering printed circuits structurally associated with non-printed electric components.
