  • Publication number: 20170223906
    Abstract: A substantially rectangular and open bottom shield configured to be fitted around an in-ground plant at ground level as enabled by an elongated slit and central aperture. A peripheral wall perpendicular to an opaque top panel extends downward around at least 75% of the perimeter of the top panel. The top panel is inclined toward the central aperture through which water and fertilizer can flow toward the plant root system.

  • Patent number: 6121169
    Abstract: The present invention is embodied in ceramic matrix composites with porous interfacial coatings and the methods and processes for fabricating such coatings integral with the ceramic matrix composites. Each ceramic matrix composite of the present invention includes a fibrous substrate or fabric material with a porous interfacial coating. The coating, prior to processing, is comprised of a coating solution made of a carbon precursor and a ceramic precursor resin dissolved directly within a solvent or solvents. Fabrication is achieved by first desizing the fibrous substrate, second immersing the desized fibrous substrate in the mixed coating solution, third evaporating the solvent and curing the precursor and resin via a low temperature cure, and fourth pyrolyzing the coating via a high temperature pyrolysis, preferably in an inert atmosphere. Next, the coated fibrous substrate is combined with a ceramic matrix composite (CMC).

  • Patent number: 5989467
    Abstract: The present invention is embodied in a ceramic foam made by mixing a liquid pre-ceramic resin and a liquid phenolic resin, allowing the resultant mixture to chemically foam, curing the mixture for a time and at a temperature sufficiently to convert the mixture to a polymeric foam, and then heating the resultant polymeric foam for a time and at a temperature sufficient to break-down polymers of the polymeric foam and convert the polymeric foam to a ceramic foam. The ceramic foam of the present invention contains residual decomposed components of the liquid phenolic resin and/or liquid pre-ceramic resin.

  • Patent number: 5695154
    Abstract: A gap filler device applicable to a gap formed between side walls of adjacent panels comprises an elongated horizontal portion extending across the gap and a vertical portion extending into the gap. The vertical portion includes a pair of opposed, spaced apart, planar bearing surface members biased into frictional engagement with the side walls of the gap to resist removal of the gap filler device. The vertical portion has descending legs extending from opposed sides of the horizontal portion to a bight. Ascending legs extend from the bight to terminal ends. Slots are formed in the vertical portion and extend upwardly from the bight at spaced locations along the length of the legs. In one embodiment, a plurality of outwardly projecting spike members are formed on the bearing surface members for engagement with the side walls of the gap.

  • Patent number: 5654014
    Abstract: A system is provided for repairing a planar sheet member which has a damaged region defined by a boundary. A generally planar repair assembly having an outer periphery initially spaced from the boundary of the damaged region is inserted into the damaged region so as to be coplanar with the sheet member. Thereupon, the repair assembly is enlarged until its outer periphery is generally adjacent to the boundary of the damaged region to be repaired. At the same time, a frangible wall in a container of the repair assembly positioned between a first compartment liquid filler material and a second compartment of liquid hardener chemically reactive with the filler material is broken such that the filler material and hardener intermix and react to form a resultant liquid repair material.

  • Patent number: 5621062
    Abstract: Solvent-free, fluid polythioether coating or caulking compositions having excellent room-temperature self-curing properties and excellent leveling properties are produced by mixing reactive liquid precursor components comprising a hydroxyl- or silyl-terminated amino polythioether of formula A and a hydroxyl- or silyl-terminated epoxy polythioether of formula B. The mixture is applied to a surface to the protected, preferably a hydrolyzable metal surface such as aluminum which is reactive with the hydroxyl or silyl terminal groups, and cured at room temperature for less than two hours to produce a self-leveling protective coating or gap-fill which is strongly-bonded to the surface and is flexible and stable over a wide temperature range between about -60.degree. F. and +360.degree. F.

  • Patent number: 5336748
    Abstract: Silane polymer coating compositions which have excellent bonding properties for metallic surfaces and which make such surfaces highly resistant to corrosion. The compositions are formed by anhydrously reacting an epoxy trialkoxy silane with a primary amino trialkoxy silane in a stoichiometric molar ratio which provides one epoxy group for reaction with each primary amino hydrogen site to form the silane polymer coating composition. The composition is applied to the metal surface, and is hydrolyzed and dehydrated in situ to crosslink thereon and bond to the surface to form the corrosion-resistant coating.

  • Patent number: 5065960
    Abstract: Improved channel members positionable over and in the gaps between aircraft panels. Each channel member includes a gap filler including a horizontal portion extending across the gap and a vertical portion extending downwardly therefrom into a gap. The vertical portion has parts in frictional contact with the side walls of the gap to resist removal of the gap filler from the gap. The gap filler is formed of an electrically conductive material selected to preclude galvanic corrosion when in contact with the panels. The vertical portion is formed of a pair of downwardly extending legs integrally formed with the horizontal portion. A central extent of each vertical portion includes an outwardly directed bight in frictional contact with a side wall of an associate panel. The channel member further includes an upper horizontal component in contact with adjacent plates at their exterior surfaces. The upper horizontal component is fabricated of the same material as the panels.
