All ingredients of these layers can be materials such as nickel, nickel aluminide, chronium, chromic oxide (Cr.sub.2 O.sub.3) and inert diluent, that do not contaminate superalloys or even low alloy or plain carbon steels. Layer can be deposited from suspension in a solution of film-former like and acrylic resin in readily volatilizable solvent such as methyl chloroform or chloroform. Innermost layer can be depletion-preventing and can be omitted. Such a holding shell can also be used to retain on a workpiece surface a layer that causes formation of a diffusion coating. Chromizing can be performed before aluminizing. Low alloy steel conduit can be internally chromized and/or externally chromized or aluminized to make it more desirable for use as high pressure steam boiler heat exchange tubing.

  • Patent number: 4522958
    Abstract: Disclosed is an essentially solvent-based, organic, high-solids coating composition containing (A) a film-forming binder system containing a crosslinkable resin having a weight average molecular weight of from about 500 to about 10,000; (B) substantially colorless, substantially inorganic microparticles stably dispersed in the coating composition; and (C) a solvent system for the crosslinkable resin. The inorganic microparticles prior to incorporation in the coating composition range in size from about 1 to about 150 nanometers and are in the form of a sol of the microparticles in which carbon-containing molecules are chemically bonded to the inorganic microparticles at the surface of the microparticles.

  • Patent number: 4521492
    Abstract: A light refractive coated paperboard is provided comprising a normally oil and grease permeable substrate, a non-leafing silver-colored ink layer applied to one surface of said substrate and a highly pigmented (titanium dioxide) ink layer superimposed on said non-leafing silver colored ink layer and possibly a clear lacquer or varnish layer superimposed on the TiO.sub.2 containing ink layer. The above order of coating layers produces a somewhat flat appearance; for producing a more metallic look the order of the silver-colored ink layer and of the highly pigmented (TiO.sub.2) layer are reversed. The light refractive coated paperboard conceals, from the outer surface of a package made therefrom, oil and grease stains which have penetrated the inner surface of the package. A method of making such light refractive coated paperboard is also disclosed.

  • Patent number: 4509906
    Abstract: A rotary compressor comprises a housing having a cylindrical inner wall surface, a rotatable sleeve having an inner and outer surfaces and disposed in the housing for rotation about a first longitudinal axis, a rotor disposed in the sleeve for rotation about a second longitudinal axis which is offset from the first longitudinal axis, a plurality of vanes carried by the rotor to extend substantially in radial directions and having radially outer edges maintained in contact with the inner surface of the sleeve so that the sleeve is rotated as the rotor and the vanes rotate. One or each of the inner wall surface of the housing and the outer surface of the sleeve has a coating comprised of a wear-resistant resin dispersed with 10 to 120 volume part of a solid lubricant and 5 to 50 volume part of metal flakes for 100 volume part of the resin.

  • Patent number: 4508640
    Abstract: An electromagnetic wave-shielding material is disclosed. The material is comprised of one or more electromagnetic wave-shielding layers and one or more surface layers. The shielding layers are comprised of a thermoplastic resin, an aluminum or aluminum alloy and electrically conductive carbon black. The surface layers are comprised substantially of thermoplastic resin. The proportion of the carbon black and aluminum in the shielding layer are from 5 to 50% by volume and 5 to 50% by volume, respectively, provided the total proportion of the carbon black and aluminum is 10 to 60% by volume. The difference in solubility parameter between the thermoplastic resin of the surface layer and the thermoplastic resin of the shielding layer is 3.0 or less. The material has superior mechanical strength and electromagnetic wave-shielding properties.

  • Patent number: 4490283
    Abstract: Flame retardant, conductive plastic molding compositions are provided in granular form comprising a thermoplastic resinous matrix through which are distributed fine, solid anisometrically shaped metallic particles in amounts totalling between about 12% and about 40% by volume. The formulation of said matrix is such that it contains at least about 24% by weight of chlorine derived primarily from vinyl chloride resins having K values between about 45 and about 70, and it also contains from about 3% to about 15% by weight of balanced lubricant/stabilizer combinations. Said anisometrically shaped metallic particles typically have aspect ratios of over about 10 to 1 and a minimum characteristic dimension of over 1 micron and are preferably composed almost entirely of conductive metal.
