  • Patent number: 4273824
    Abstract: A method of adhering a ceramic facing material to an underlying substrate is disclosed. Substrates to which the concepts apply include unsupported low modulus, porous wire pads as well as low modulus, porous wire pads backed by a solid metallic form. The ceramic application techniques employed are centered around the impregnation of the regions of the pad to be ceramic coated with an underlayment coating, such as MCrAlY material, wherein the designation "M" stands for at least one of the elements from the iron cobalt and nickel group. Deep penetration of the underlayment material into the pad is achieved with a high velocity, spraying process. Ceramic material is applied over the underlayment material by conventional spraying techniques.Articles of manufacture which are suited to fabrication in accordance with the concepts disclosed herein include, but are not limited to, outer air seals, combustion chambers, and airfoils of gas turbine engines.

  • Patent number: 4270967
    Abstract: This invention concerns an improved gluing machine and a continuous method of operation which allows the gluing process to proceed at a rate that equals the feed rate of vacuum rotary document feeders. The machine includes a unique registry and guide system for efficiently moving documents fed initially in an individual manner in a continuous, flowing manner from an initial input feed device to the gluing and registry point with the carrier. The feed system not only allows substantially greater operating speeds but simultaneously overlaps documents while establishing and maintaining correct registration of the documents. The documents are overlapped so that following documents are positioned beneath leading documents. This overlapped condition together with the registry achieved within the feed system assures each individual document arrives in proper registry with areas of glue previously applied at preselected intervals on the carrier sheet.

  • Patent number: 4259401
    Abstract: A building element which inhibits the change of the interior temperature of a building beyond prescribed limits approximating room temperature. A rigid porous matrix structure is provided in thermal communication with the building interior. A store of phase change material impregnates the matrix structure. The phase change material has a melting point within the temperature limits so that the material melts when the interior temperature of the building exceeds the temperature limits. Melting of the material absorbs heat and reduces the interior temperature of the building, until the material is entirely melted. Conversely, the material freezes when the interior temperature of the building falls below the temperature limits to release heat and increase the interior temperature until the stored material is entirely frozen. The store of phase change material is sealed within the matrix structure so that the material undergoes repeated changes in phase between liquid and solid.

  • Patent number: 4254179
    Abstract: A method and apparatus for impregnating a porous foam product with a fragrance which is released over an extended period of time. The method includes the steps of depositing scented particles on one surface of the foam and dispersing the particles within the foam by supplying heat to the foam and applying a vacuum to the opposite surface of the foam. Fragrance or fragrance particles may also be added directly to the foam during its manufacture and a semi-permeable film or fabric may also be affixed to the scented porous foam product to retard and thus extend the release of the fragrance. In a preferred embodiment, frangible encapsulated particles of fragrance are used so that the encapsulated fragrance is retained within the foam until it is later utilized and subject to external forces which break the capsule to release the fragrance.

  • Patent number: 4251597
    Abstract: Addition polymers containing a plurality of terminal and/or pendant amine groups in which the nitrogen atom of at least some of such groups is of primary or secondary character, or aldimine or ketimine groups form the main film-forming component in compositions for coating and the like purposes, which also contain a polyfunctional acrylic monomer, such as ethylene glycol diacrylate, with or without monoethylenically unsaturated acrylic ester. Such compositions provide durable films having excellent mechanical and resistance properties even on ambient curing though baking may be used to accelerate the cure.

  • Patent number: 4248924
    Abstract: Porous film materials composed of polytetrafluoroethylene having an asymmetric structure are produced by stretching the film using a pair of revolving rolls which are heated to a temperature lower than the melting point of the film. Stretching is produced by revolving the two rolls at different speed which also tends to produce a compressive force in the thickness of the film. The rolls are heated to different temperatures to produce a temperature difference of preferably 50.degree. C. or more. The combination of the compressive force and the temperature gradient in the thickness of the film is believed to produce the asymmetric structure in the resulting porous film materials which are characterized by a fiber structure in the front surface which is different from that in the back surface.
