  • Patent number: 4321425
    Abstract: There is disclosed a lattice cable and a method of making said, said lattice cable having a plurality of elongated insulated elements extending parallel to one another and uniformly spaced apart by integrally formed insulative ribs there between, the elongated insulative elements and the insulative ribs being constructed of a material having a first dielectric constant. At least every other one of the elongated insulative elements having an elongated electrical conductor partially embedded in the surface thereof so that a portion of the surface of the elongated electrical conductor is exposed along the length thereof, the elongated electrical conductors passing through and being covered by the integrally formed insuative ribs so that the exposed portion of the elongated electrical conductors is located between the insulative ribs. Each lattice cable thus formed may be placed in a layered combination with one or more other lattice cables.

  • Patent number: 4230898
    Abstract: There is disclosed a lattice structure having a plurality of elongated parallel elements interconnected periodically by integrally formed ribs therebetween and a plurality of elongated filaments, each of which is embedded in and adhered to one of the elongated parallel elements. The structure is constructed by a method which includes the steps of molding the lattice structure from film or laminate belts, heating the filaments above the melting temperature of the molded lattice structure, joining the heated elements with the structure and solidifying the lattice structure adjacent each filament.

  • Patent number: 3951713
    Abstract: A method and apparatus for insulating a plurality of electrically conductive elements and to produce electrical cable where the method includes heating the unformed insulative material and conductive elements, applying pressure and simultaneously removing heat with a pair of rollers at a relatively low temperature and applying pressure and heat to preselected regions only of the insulative material. The method and apparatus further allow preselected portions of the cable to be unbonded so as to facilitate access to the conductive elements by simply interrupting the application of pressure to the preselected portions. The heat, press and cool and press and bond method may also be accomplished in a step and repeat process using presses to insulative flexible circuits. The above method and apparatus provide more reliable bonding at an accelerated rate of production.
