    Abstract: A radio frequency filter for a television receiver adapted for coupling to an alternating current source having an earth ground and including a conductive chassis which, upon energization of the receiver by the current source, is coupled to one terminal of the current source and a radio frequency tuner coupled to the chassis. A coaxial cable utilized to couple radio frequency signals between a source of radio frequency signals and the tuner has inner and outer conductors. Capacitors are provided between the outer conductor and the chassis of the television receiver at a first point, a second point and a third point along the coaxial cable, the first point being adjacent the tuner and the second and third points being progressively further from the tuner. First means for elevating the impedance associated with at least the outer conductor of the coaxial cable while maintaining the characteristic impedance of the coaxial cable as a whole is associated with the outer conductor between the first point and the second point. Second means for elevating the impedance associated with at least the outer conductor of the coaxial cable is associated with the outer conductor between the second point and the third point. The combination of the means for elevating the impedance of the outer conductor and the capacitors provide for a reduction of undesirable radio frequency signals coupled to the tuner which are developed between the outer conductor and earth ground by electromagnetic radiation coupled to the coaxial cable between the source of radio frequency signals and the third point.

    Abstract: Circuits for indicating the order in which two concurrent signals arrive and the period during which both signals are present. These circuits include two signal powered switches, such as transistors, each receptive of a different signal. When the first arriving signal is present it closes its switch and the closed switch keeps the other switch open. Circuits controlled by the respective switches produce output indications, each during the period a switch is both open and receiving the second arriving one of the signals.

    Abstract: A color image intensifier and projector includes a reflective light valve lamination having, in order, a flexible conductive mirror, a deformable layer, a photoconductive layer, a transparent conductive layer, and a plurality of optical diffraction gratings each for a different color. An electric potential is applied across the flexible conductive mirror and the transparent conductive layer to bias the photoconductive layer. When an input colored image is projected through the gratings to the photoconductive layer, the resulting electric fields cause the deformable layer and flexible conductive mirror thereon to be deformed in accordance with the colored image as modified by the diffraction gratings. A Schlieren optical system is included to direct light from a source to the flexible conductive mirror, and to collect reflected light and direct it through a fourier transform plane to a utilization plane. A color-decoding spatial filter is located in the fourier transform plane to recreate the color image at the utilization plane.

    Abstract: A layered information record contains superimposed frames of information wherein a first frame contains luminance information of a scene as density variations of a cyan dye. A second frame superimposed on the first frame contains color encoded chrominance information as density variations of a yellow dye. In a system for playing back the layered information record, white light is projected through the superimposed first and second frames of information and viewed through a red filter for extracting the monochromatic luminance information and a blue filter for extracting the monochromatic color encoded chrominance information.

    Abstract: A layer of substantially uniform lead monoxide is vapor deposited on a supported signal electrode of a vidicon target. The lead monoxide layer is formed on the signal electrode as a substantially homogeneous compensated intrinsic, or n type, electrically conductive material. An electrical potential is applied to the supported layer of lead monoxide to affect an electrical discharge through a continually renewed atmosphere consisting essentially of one of the inert gases, or nitrogen, whereby ion bombardment of the layer is accomplished.

    Abstract: A shaft is utilized for fastening a pair of core members together and for mounting the pair of core members onto a mounting platform. The core members include recesses which contain an electronic component. The shaft extends through the core members and projects beyond a surface of each of the members. The shaft includes a flange abutting one of the core members. A fastener slidably located on the shaft mechanically fastens the pair of core members together and against the flange. The assembly can be easily assembled and mounted onto a mounting platform by inserting one end of the shaft through an opening in the platform.

    Abstract: Exact replication of soft substrates can be achieved by depositing, as by evaporating, a first thin layer of chromium followed by a thin layer of gold and then electroplating a layer of bright nickel. This combination of metals produces an exact replica of the soft substrate without stress or distortion and has utility in the preparation of a metal master for mass produced replicas having low noise.

    Abstract: The transistor comprises a number of spaced apart emitter sites within a semiconductor wafer connected together by metal contacts overlying the wafer surface. Each emitter site comprises two sections which extend transversely of one another, the configuration of the sites contributing to a greater emitter peripheral length while not increasing the base area. The connection to each emitter site is through a layer of resistive material overlying the wafer surface, the resistive material layer providing ballasting for each site and being so arranged relative to each site to provide relatively uniform ballasting of each portion of each site.
