Abstract: Disclosed is a perforated circuit board with a linear arrangement of paired terminals through which jumper wires are inserted and which are positioned on each side of and adjacent to the perforations. The perforations permit flexible "breaking" of the circuit board into sections which may be oriented at any angle relative to one another while the machine-inserted jumper wires provide structural integrity and rigidity for the circuit board arrangement thus formed in addition to electrical coupling between adjacent board sections.

Abstract: An easily installed thermal coupler inserted in the extruded section of a heat sink on which a transistor amplifier is mounted and positioned on a circuit board in thermal contact with diode biasing means coupled to the transistor amplifier. By thus thermally coupling the biasing means with the amplifier in a self-correcting, negative feedback loop, stable transistor operation is achieved and thermal runaway prevented. Employing a unitized metallic heat conducting member having a base plate including connecting studs for circuit board mounting and an upright member extending therefrom, the heat coupler may be used as either a heat sink or heat transfer device in carrying heat either out of or into the circuit board.

Abstract: A television cabinet defines a cavity within which a CRT and associated circuitry are supported. The base portion of the cabinet defines three internal channels. A module support, formed of nonconductive material, defines three internal channels which support three printed circuit modules. Three flanges formed on the lower portion of the module support coact with the cabinet base channels to permit slide mounting of the module support, bearing the printed circuit modules, within the cabinet enclosure. A cabinet back includes a retaining surface which abuts the ends of the module support channels to retain the modules therein. The module support is stackable with other module supports while bearing the printed circuit modules thereby serving as a transportation carrier therefor.

Abstract: A television receiver includes a plurality of printed circuit modules bearing signal processing and display producing circuitry. A centralized regulated power supply converts the alternating line power to a number of operating voltages. Individual supply and ground return lead pairs connect each module to the central power supply to the exclusion of the remaining modules. Arc suppression circuitry is provided which includes ground return paths distinct from the supply or ground return leads connecting the modules to the power supply.
