Abstract: ABSTRACT OF THE DISCLOSURE             A method for producing composite ceramic shell molds for investment casting and subsequent directional solidification of nickel and cobalt base superalloys is described.  The composite ceramic shell mold is composed of an inner component having an alumina content of at least 80 percent and an average thickness of about ten mills and an outer layer com-posed predominantly of zircon having a thickness of from .1 to .4 inches.  The alumina component of the shell mold is wet by the superalloy material and this wetting action is believed to cause the substantial elimination of a surface defect problem know as chain porosity.  The zircon component of the shell mold had desirable mechanical properties and my easily be removed from the solidified casting.  The alumina and zircon components are bonded together in such a fashion that they will not separate during the casting process.

Abstract: Composite semipermeable membranes are made by reacting a film-forming polymer with a cross-linking monomer to form a polymeric ultrathin film having semipermeable properties.  During the formation, a grafting reaction is carried out at reactive sites so there are few remaining active sites where oxidising attack or fouling can potentially occur.  One composite membrane comprises a microporous substrate and an ultrathin polyamide film formed of polyethylenimine cross-linked with a monomer, such as an acyl halide, a chloroformate, an isocyanate or a sulfonyl chloride.  Grafted onto the cross-linked polyethylenimine at what would otherwise be secondary amido sites is an epoxide, an aldehyde, an anhydride or a reactive ethylene compound.

Abstract: ABSTRACT        A system, designed to cure an ultraviolet sensitive coating on a substrate that is moving in a direction transverse to the radiation emitted from the system, which includes a plur-ality of arrays of short-arc ultraviolet lamps, each array lo-cated in a suitable housing.  The arc of each lamp in a given array is located at the focus of an associated paraboloidal re-flector mounted within the housing so that at least half of the ultraviolet radiation emanating from the arc is reflected by the paraboloidal reflector to produce a collimated beam of ultra-violet radiation directed toward a concave spherical reflector whose center is located axially with the paraboloidal reflector.          As measured between the two reflectors, the axis of the spheri-cal reflector normally forms a forty-five (45°) degree angle with respect to the axis of the paraboloidal reflector to reflect the collimated beam toward the substrate.  Because of the con-cave surface of the spherical reflector, the radiant energy is focused to a small area on the substrate.  This area is adjust-able over a wide range depending on the focal lengths of the spherical and paraboloidal reflectors which are chosen so as to arrive at the most desirable intensity of radiation for the par-ticular sensitivity of the coating being treated.  Each array produces a set of disconnected high intensity image areas on the substrate, with the totality of arrays providing complete cover-age across the width of the substrate.  Within each array, the spherical reflectors are mounted as an assembly within the hous-ing for pivotal movement into a position to reflect the focused beam 180 degrees from its normal direction so that no energy strikes the substrate when it is not in motion.

Abstract: MULTILINE EMISSION INTEGRAL MIRROR LASER     ABSTRACT OF THE DISCLOSURE     An integral mirror type laser system which  produces multiline emissions simultaneously and which is adapted for use in optical data processing systems.  In particular, in a first embodiment, a unitary positive column laser comprises two sections, the first section comprising a positive column helium-cadmium laser, the second section comprising a positive column helium-neon laser, the first and second sections being coaxially aligned and having different inner diameters.  Simul-taneous excitation in the two different sections provides optimum excitation for red laser light, produced by the helium-neon section and blue laser light produced by the helium-neon-cadmium section.  The present system also allows separate cadmium vapor pressure control by separately controlling the varporization temperature of the cadmium and also allows con-finement of the cadmium vapor whereby the vapor does not contaminate one of the optical windows which confines the active laser medium.  By proper selection of the optical cavity parameters, simultaneous red and blue laser oscilla-tions can be obtained for application in any optical data processing system that requires a red and blue laser radiation source.  In a second embodiment, the helium-cadmium section is replaced by with a helium-selenium section whereby the tandem laser system is capable of producing multiline laser radiation in the red, blue and green colors.

Abstract: Abstract of the Disclosure The crab trap is a multi-component trap adapted to be stripped down to its respective components for storage.  It comprises spaced top and bottom closure members and posts detachably interposed therebetween to form an open-sided cage.  Normally open crab entry means are attached to the cage adjacent the openings on opposite sides thereof, and normally-closed operator entry means are attached to the cage adjacent a remaining side opening thereof.  Any additional side openings are also closed to the outward movement of crabs, so that crabs entering the cage through the crab entry means, remain trapped therein.  However, the crab entry means, the operator entry means, and the additional closure means, if any, are all removable from the openings thereadjacent in the cage, so that when the trap is out of use and the posts are detached from the top and bottom closure members, the members can be stacked on top on one another in a pile.

Abstract: RCA 69,527 ANTENNA SYSTEM WITH AUTOMATIC   DEPOLARIZATION CORRECTION          Abstract A spectrum reuse antenna system is described for transmitting orthogonally polarized RF waves at one frequency band to a satellite and for receiving orthogonally polarized RF waves from a satellite at a second frequency band through a common antenna.  A local generator provides a first control signal which varies as a function of the typical rotation of the polarization of a transmitted wave at the one frequency band travelling through the ionosphere.  The local generator also provides a second control signal which varies as a function of the typical rotation of the polarization of a received wave at the second frequency band travelling through the ionosphere. A driven means responsive to the first control signal causes a rotation of the polarization of the transmitted waves to correct for Faraday rotation in the ionosphere and a driven means responsive to the second control signal causes rotation of the polarization angle of the antenna system for the received waves to correct for the Faraday rotation.

Abstract: Application of Edward F. Meihofer George F. Corcoran John W. Clifford For DRIVEN NIP ROLL SPLICER                    Abstract of the Disclosure Web splicing apparatus employs a pair of driven nip rolls which controllably feed web from a running roll into a festoon as web is drawn out of the festoon at a constant rate by a down-stream web consuming machine.  The nip rolls are driven by a DC motor connected in a closed loop servo system which compares the speed of the web entering the festoon with the web line speed to develop a command signal for the motor.  During normal operation, the command signal includes a web velocity trim signal developed by monitoring the position of the festoon dancer relative to a selected reference position so as to minimize tension upsets and to maintain the dancer within its control range.  During a splice sequence, the command signal comprises a deceleration ramp having a selected slope to provide controlled deceleration of the web to minimize tension upsets and to permit actuation of the splicing nips prior to actual web stop.  After the splice is made, the command signal comprises an acceleration ramp whose slope is automatically adjusted to apply the least necessary tension to the ready web for new roll acceleration consistent with a given splicing speed.  Further with this arrangement, the  gain of the system is independent of the changing size of the expiring roll.

Abstract: ABSTRACT OF THE DISCLOSURE        The response of an automatic control system to a general input signal is improved by applying a test input signal, observing the response to the test input signal and deter-mining correctional constants necessary to provide a modified input signal to be added to the input to the system. A method is disclosed for determining correctional constants. The modified input signal, when applied in conjunction with an operating signal, provides a total system output exhibiting an improved response. This method is applicable to open-loop or closed-loop control systems. The method is also applicable to unstable systems, thus allowing con-trolled shut-down before dangerous or destructive response is achieved and to systems whose characteristics vary with tire, thus resulting in improved adaptive systems.
