  • Corrosion resistant filler weld alloys
    Patent number: 5139738
    Abstract: A corrosion resistant filler weld alloy is provided for use in repairing a preselected article alloy of predetermined composition range at a temperature equal to or greater than the incipient melting temperature of the article alloy, the filler weld alloy having a composition, by weight of:Chromium--from about 20% to about 48%Nickel--about 20%Tungsten--from about 0% to about 4%Carbon--about 0.1%Silicon--about 0.9%Manganese--about 0.6%Tantalum--from about 0% to about 3.5%Titanium--from about 1% to about 2.25%Cobalt--Balance.

  • Apparatus and method for sensing diaphragm failures in reciprocating pumps
    Patent number: 4781535
    Abstract: Apparatus for monitoring the diaphragm integrity in a diaphragm pump. A single continuous circuit trace is supported on a pump diaphragm. An electrical circuit is connected to the continuous circuit trace for measuring both the continuity and a potential ground fault condition between the circuit trace and pumping liquid. The circuit trace is formed in a configuration which resists the effects of strain induced by continuous flexing of the diaphragm.

  • Foundry mold treating compositions and methods of making same
    Patent number: 4289803
    Abstract: Phosphosilicate compositions are disclosed for treating foundry molds and like products to enhance mold strength and refractoriness. The phosphosilicates, characterized more specifically as silicyl metaphosphates, may be used in combination with select refractory aggregates and other additives to form mold surface treating compositions, or may be combined directly with foundry sand or other comminuted refractory material for compacting into a mold form.
