  • Patent number: 5247000
    Abstract: A fiber optic adhesive composition for applying to a fiber optic having a ffer coat thereon and subsequently, partially cured to a tacky outer surface prior to its being wound onto a bobbin from which the adhesively coated fiber optic material is to payout during use to transmit a signal to a missile in flight. The partially cured adhesive composition functions to hold the fiber optic material in place on the bobbin during storage and allows consistent payout during use of the fiber optic material. The typical composition of the fiber optic adhesive comprises hydroxyterminated polybutadiene from about 88.14 to about 92.48 percent by weight, isophorone diisocyanate from about 6.23 to about 6.42 percent by weight, a catalyst of ferric acetylacetonate or dibutyltin dilaurate in an amount from about 0.89 to about 1.15 percent by weight respectively, and a thixotropic agent in an amount of about 4.48 by weight.

  • Patent number: 5194112
    Abstract: Disclosed is a method and a fiber optic adhesive which composition is appd to a fiber optic having a buffer coat thereon and is, subsequently, partially cured to a tacky outer surface while being wound onto a bobbin from which the adhesively coated fiber optic material is to payout during use. The adhesively coated fiber optic material must be cured to a tacky cure while being wound onto a bobbin. The cured adhesive composition functions to hold the fiber optic material in place on the bobbin during storage and allows consistent payout during use of the fiber optic material. The typical composition of the fiber optic adhesive comprises hydroxyterminated polybutadiene from about 88.14 to about 92.48 percent by weight, isophorone diisocyanate from about 6.23 to about 6.42 percent by weight, a catalyst of ferric acetylacetonate of dibutyltin dilaurate in an amount from about 0.89 to about 1.15 percent by weight respectively, and a thixotropic agent in an amount of about 4.48 by weight.

  • Patent number: 5002797
    Abstract: Aluminum-coated ammonium perchlorate is prepared in an apparatus consisting f a four-opening reaction flask (which serves as a vacuum chamber). The reaction flask is fitted with an electrically-heated tungsten helix coil (for vaporizing the aluminum), a mercury diffusion pump, a mechanical vacuum pump, a dry ice-acetone-cooled trap, and a McLeod pressure-measurement gage. The heater electrodes are submitted through two of the openings; reduced pressure operation is maintained through the third opening, and the aluminum is fed through the fourth opening. The reaction flask is operated at approximately 10 Torr. A magnetic stirrer permits the ammonium perchlorate to be vaporized onto the surface of the ammonium perchlorate after the melted aluminum on the tungsten helix coil is subsequently vaporized from the tungsten helix coil.

  • Patent number: H844
    Abstract: Optical energy is conveyed through a region and is subsequently converted to electrical energy when it reaches the area of its intended use. Spatially multiplexed laser light is transmitted through an optical fiber to convey the energy through the area. Several light beams or several light beam paths may be used to convey a plurality of beams of light energy into an area either simultaneously or sequentially. Typically, two light beams enter the fiber at different angles of incidence, resulting in a first annulus of laser light that impinges on a first photocell and a second annulus of laser light that impinges on second photocell. This sequence continues alternately with the electrical outputs of the two photocells being coupled to a step-up transformer to provide electrical power for a system of interest, and or the energy being directed to a communication circuit for removing intelligence signals therefrom.

  • Patent number: H855
    Abstract: Optical power is supplied to a remote location and switched between conveon circuits for converting the optical power to electrical power to remotely power a system or device. Laser light is guided by a fiber optic to illuminate photovoltaic cells to produce the electrical power. The electrical current from the cells is made to alternate by switching the light between the cells and using a transformer to step up the voltage. This allows power to be supplied to a remote area without disrupting the existing electromagnetic fields in the area and where space and voltage requirements are limited such that the use of many photovoltaic cells is prohibitive.

  • Patent number: H925
    Abstract: An encapsulated signal illuminant flare composition is comprised of powde magnesium from about 45 to about 60 weight percent, of powdered sodium nitrate from about 32 to about 49 weight percent, and of capsular adhesives containing about 91 weight liquid materials contained within capsules having cell walls of equal parts Arabic gum and gelatin of about 9 weight percent to yield a binder from about 6 to about 12 weight percent. The composition ingredients are blended in a dry mixer to achieve a homogeneously, blended signal illuminant flare composition. The blended signal illuminant flare composition is incrementally fed into a flare press for compacting into cartridges in two increments at about 14,000 psi pressure which ruptures the capsular adhesives by hydraulic forces to achieve polymer mixing and the surrounding of the powder ingredients with the binder ingredients to form a very homogenous signal illuminant flare composition mass.

  • Patent number: H934
    Abstract: Maleic anhydride, MAN, as an adjunct to triphenylbismuthine (TPB) yields roved benefits to the mechanical properties of isophorone diisocyanate cured hydroxy terminated polymer binders. Results from several propellant mixes indicate that both pot life and mechanical properties are affected not only by the concentration of TPB catalyst used, but also by the ratio of TPB to MAN. The ratio of TPB to MAN from about 1 to 0.5 to about 1 to 1.5 produces interesting results in the values of stress, strain, and modulus as shown in the data set forth in the specification and as graphically depicted in the drawing. The weight percent of MAN ranges from about 0.0125 percent to about 0.0375 percent, and the weight percent of TPB ranges from about 0.015 percent to about 0.035 percent.
