  • Patent number: 5238510
    Abstract: Disclosed is a method for producing a metal sheet having a full-hard central portion extending between at least two softer side edge portions of the sheet. The method comprises the step of heating the side edge portions of the sheet portions of the sheet to a higher temperature than the central portion.
    Type: Grant
    Filed: December 4, 1991
    Date of Patent: August 24, 1993

  • Patent number: 4019901
    Abstract: An ultra-high strength steel composition of matter having a substantially martensitic matrix with a dispersion therein of a critical amount of metal oxide particles and characterized by increased resistance to environmental stress corrosion cracking. The metal oxide particles are selected from the group consisting of CaO, BaO, MgO, SrO and mixtures thereof, in the range of 0.1 to less than 3 mole percent. A powder metallurgy process to produce articles of manufacture from the composition of matter is disclosed.

  • Patent number: 3945795
    Abstract: Damage due to rupture or ballooning of the plastic jacket on a flexible pumping strand due to filling of the well with gas is prevented by providing an assembly including a preset pressure release valve in the lower portions of the strand to quickly release fluid from the interior of the strand to the surrounding environment upon the attainment of a pressure differential between the interior and exterior of the strand within a predetermined fraction of the rupture or ballooning strength of the plastic jacket on the pumping strand.
