He afterward cut the estimate, in half to be conservative, which was equivalent to 10 ft. thickness of ore on onetenth of the surface. This would give 2,700,000 tons per square mile or on 900 sq. miles in New Jersey 2,300,000,000 tons, with a goodly area in New York tofall back on to make up deficiencies.

loyed base metals contain small amounts ofcop­ per (% max), niobium (% max), and nitrogen (% max) and have mechanical propertiescomparabletothose of duplexstainless steels. Typically these HSLA base metals have yield strengths of 500 MPa ( ksi) and impact values of 60 J (44 ftlbf) at60°C(75OF). The

Wear of polyethylene (UHMWPE) is dependent on crossshear. The aim of the present study was: 1) to develop a theoretical description of crossshear, 2) to experimentally determine the relationship between crossshear motion and UHMWPE wear using a wheelonflat apparatus, and 3) to calculate the work it takes to remove a unit volume of wear for the use in advanced computational models of wear.

In the ball mill process, metallic lead balls are tumbled in air to produce a "leady" oxide, which typically contains 20 to 35 % free lead. The Barton pot process oxidizes droplets of molten lead at ca. 430 deg C to produce either litharge or leady litharge.
