    Abstract: A diaphragm article includes an elastomer body reinforced with a pulp dispersion of polyaramid fibers. The elastomer has a material composition consisting of a silicon and/or fluoro-silicon polymer. The elastomer is blended with fiber to produce a heterogenous mixture. A compression molding process is used to fabricate the diaphragm, where a composition of aramid reinforced elastomer is employed as the preform structure. The diaphragm structure provides an increased strength and stiffness threshold. One diaphragm form includes fibers oriented generally orthogonally to the central pressure axis to provide improved radial stiffness. The diaphragm construction may be augmented with fabric reinforcement to provide further improvements in durability and performance.

    Abstract: A process for producing a low alloy white cast iron is disclosed. The process comprises the steps of selecting one of a group of four alloying elements for a nickel, molybdenum/copper or modified low alloy iron; the four alloying groups consisting essentially, by weight percent of about:Group 1: 2.5 to 4.0% carbon; 0.3 to 0.8% silicon; 0.3 to 0.8% manganese; 0.75 to 2.0% nickel; 0 to 0.75% chromium.Group 2: 3.0 to 4.5% carbon; 0.3 to 0.8% silicon; 0.3 to 1.0% manganese; 0 to 0.8% molybdenum; and 0.3 to 1.0% copper.Group 3: 3.0 to 4.5% carbon; 0.3 to 0.8% silicon; 0.3 to 1.0% manganese; and 0.3 to 0.8% copper;the balance being iron except for incidental impurities commonly found in cast irons; melting the alloy; casting such alloy into moulds to produce the desired product; removing the product from the moulds while its surface temperature is above the transformation temperature of the alloy; and cooling it by quenching into a liquid medium containing water and an organic polymer at a sufficiently high rate to prevent the formation of pearlite but not so high as to generate cracks in the product.
