  • Patent number: 11718064
    Abstract: A light weight flexible flame, arc flash and flash fire resistant fabric for protective garments is made from a flexible polyvinylchloride sheet having phthalate or phthalate free plasticizers coated with well defined parallel lines or grids of adhesive layer. The adhesive coated polyvinylchloride sheet contacts a non-woven meta-aramid fiber liner and is heated to produce a bond between the polyvinylchloride sheet and the liner. Both polyvinylchloride sheet and meta-aramid non-woven liner resist heat. When heat from arc flash or flash fire is applied, the heat is conducted away at local contacting regions of the adhesive with the polyvinylchloride sheet to the liner whereby the temperature of the polyvinylchloride is locally reduced preventing sagging, charring or burning of the space between adhesive contacting regions. This structure produces mechanically strong lightweight arc flash and flash fire resistant fabric suited for producing garments that meet all ASTM specifications for fireproof garments.

  • Patent number: 9579532
    Abstract: Provided among other things is a breach or contamination indicating elastomeric article for indicating a breach or contamination by a selected chemical or group of chemicals, the article having an exterior and interior and comprising: (a) an interior elastomeric layer selected to resist permeation by the selected chemical(s), which interior layer is colored; and (b) a contiguous or dis-contiguous indicating layer comprising solid particles of hydrophobic dye effective to provide enhanced color on contacting hexane, cyclohexane, xylene, ethyl ether, butyl acetate, MIBK, methanol, acetonitrile and acetic acid; wherein the distribution of the indicating layer provides for a visually noticeable color change against the background of the colored interior elastomeric layer upon a breach or contamination event by a selected chemical.

  • Patent number: 5273569
    Abstract: A composite has a magnesium base metal matrix and a reinforcing phase. The composite is produced from a charge containing a rapidly solidified magnesium base alloy and particles of a reinforcing material present in an amount ranging from about 0.1 to 50 percent by volume of the charge. Ball milling the charge energetically enfolds metal matrix material around each of the particles, while maintaining the charge in a pulverant state. Consolidation of the charge provides a mechanically formable, substantially void-free mass.

  • Patent number: 5167480
    Abstract: A rivet is formed from a friction-actuated extrustion. The extrusion is produced by a process that utilizes a comminuted rapidly solidified aluminum alloy ribbon as the in-feed for a continuous friction-actuated extruder. Gumming and flow problems are eliminated. The extruded product is devoid of surface blistering. The extrusion is converted into a rivet that has improved ambient and elevated temperature mechanical properties.
