Abstract: DIELECTRIC AND METHOD OF COATING SAME ONTO A SUBSTRATE       Abstract of the Disclosure A formulation comprising, by weight, 4.7-39.7 percent polymethylmethacrylate (PMMA), 0-9.1 percent plasticizer and 60.3-93.0 percent dielectric glass (along with an appropriate amount of solvent) is ball milled to an appro-priate size for spraying.  After the formulation is sprayed onto a substrate, it is baked at a temperature of approxi-mately 620°C for approximately 2 hours.  During the baking step, the PMMA decomposes to a methylmathacrylate monomer.          The resultant dielectric coating will contain a small amount of residue (less than 1 percent) of the monomer and the plasticizer.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to an improved hermaphroditic connector assembly for use with an airline. Hermaphroditic connectors employ two identically sized and shaped connectors, each secured to a respective RF or high frequency cable or airline usually by means of a respective con-nector body threaded onto the respective airline. It is important to ensure proper axial alignment of the semi-rigid or non-rotatable airlines including the conductors and contacts so that their connecting end faces meet axially along the desired plane. The present invention provides an improved hermophroditic RF connector assembly used on an airline and employing a spring biased registration ring having axially extending teeth with cam surfaces for engagement between teeth on a mating regis-tration ring of another airline connector assembly in response to rela-tive rotation between the rings to align the mating contact surfaces of two mating airlines, A coupling nut on one connector assembly is threaded over the registration ring of the other connector assembly to secure the assemblies and airlines to each other and the coupling nut of one assembly may also be partially threaded over the registration ring of the respective assembly and then used to retract the respective ring against the spring bias to provide facile means to the contact surfaces. A retaining nut on each assembly frictionally engaged with the respective connector body of the assembly enables the coupling nut to be threaded without requiring a special effort to hold the connector body from becoming loose.

Abstract: A B S T R A C T In a method of making a cross-linked extruded product from polyethylene of other suitable polymer, the polymer is metered into a screw extrusion machine together with compound-ing ingredients comprising a hydrolysable unsaturated silane, a free-radical generator and a silanol condensation catalyst. The compounding ingredients are blended with the polymer in the barrel of the extruder and the mixture is heated sufficiently to effect grafting of silane groups to the polymer, the amount of free-radical generator being sufficiently low to limit direct free-radical cross-linking to a level that will not prevent ext-rusion of the material. The reaction mixture is extruded directly from the same extruder through an extrusion die to form an elong-ate shaped product and cross-linking is effected by subjecting the shaped product to the action of moisture.

Abstract: Abstract of the Disclosure An image generator including a visible edge encoder which receives information defining the visible surfaces of a two-dimensional projection of a three-dimensional world and provides encoded two-dimensional visible edges which are x-ordered and are ready for transmission to a plurality of display terminals.  The information received by the visible edge encoder defines the x and y intercepts, in successive planes which include the observer's eye and successive scanlines of all three-dimensional edges which would be visible to the observer.  The information provided by the visible edge encoder is edges which represent a two-dimensional projection of three-dimensional objects, each edge defined by its intended position on a two-dimensional screen and by attributes for a portion of the screen adjacent the edge, such as color, brightness, shading and the like.  The edges provided by the visible edge encoder and transmitted to the display terminals, where they are decoded into video raster points, are a highly compressed representation of a video raster; hence, the communication link between the image generator and the terminals can have a relatively low capacity, and the same image generator can service a substantial number of display terminals.

Abstract: PROCESS FOR FORMING A LAYERED PAPER WEB HAVING IMPROVED  BULK, FLEXIBILITY, TACTILE IMPRESSION AND ABSORBENCY                 AND PAPER THEREOF     Abstract of the Disclosure A wet-laid composite, soft, bulky and absorbent paper structure is prepared from two or more layers of furnish which are preferably comprised of different fiber types.  The layers may be formed from the deposition of separate streams of dilute fiber slurries, the fibers typically being relative-ly long softwood and relatively short hardwood fibers as used in tissue papermaking.  The layers are combined to form a unitary web, and the layered, unitary web is de-watered.  The moist, layered web is thereafter transferred to an open mesh drying/imprinting fabric.  The application of a fluid force to the web creates patterned discrete areas of fibers numbering from about 100 to about 3600 per square inch of projected surface area on the side of the web which contacts the drying/imprinting fabric.  These layered structures exhibit significantly improved bulk, flexibility, compressibility, drape and absorptive capacity when compared to prior art paper sheets formed by similar processing tech-niques from a single slurry comprised of a homogeneous mixture of similar fibers.  In addition, the structures which are stratified with respect to fiber type typically yield finished paper sheets having significantly improved tactile impression and softness.

Abstract: ABSTRACT OF THE DISCLOSURE     An arrangement of communication components to provide communications between a central control center and various customer load locations in an electrical power distribution system.  Control or interrogation signals are originated at the control center and transmitted over a suitable facility, such as a telephone line, to an FM broad-cast station.  The control signals frequency modulate an ultrasonic subcarrier which modulates the FM broadcast transmitter simultaneously with the normal broadcast program material.  Radio receivers at the customer load locations receive, filter, and decode the broadcast signals which are used to activate the control or logic circuits associated with the customer location.  A reply signal is generated at the customer location and applied to the power lines by carrier techniques.  The power line carrier reply signal is remotely detected by a suitable receiver and transferred over a suitable wire line facility which terminates at the control center.

Abstract: Abstract of the Disclosure Propeller hubs and the hollow inner ends of propeller blades are filled or substantially filled with a liquid so that cracks in the hub wall or the blade wall leading from the interior to the exterior surface provide a pathway for the liquid to flow out to the exterior thereof, thus providing a visual indication of the presence of a crack prior to a catastrophic failure of the part.          The liquid may be sealed in the blade or hub or may be carried within the hub as a lubricating fluid, partially or substantially filling the hub.  The liquid may contain a dye to enhance visibility even of very small amounts which flow to the surface when the propeller is subjected to centrifugal force.  Maintenance personnel and/or operators may then periodically inspect the exterior of the hub and/or blade to check for any evidence of the indicator liquid on the exterior surfaces or on the adjacent aircraft surfaces as a warning of possible incipient crack or fatigue failure.
