Patents by Inventor Michael Larson

Michael Larson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hot working of metal powders
    Patent number: 4077109
    Abstract: Metal powders are hot isostatically pressed in a can or container produced from superplastic metal sheet.
    Type: Grant
    Filed: May 10, 1976
    Date of Patent: March 7, 1978
    Assignee: The International Nickel Company, Inc.
    Inventor: Jay Michael Larson
  • Porosity reduction in inert-gas atomized powders
    Patent number: 4047933
    Abstract: Thermally induced porosity, which can lead to cracking in metal powders after consolidation, is believed to be caused by the entrapment of the inert gas used for atomization within the metal powders. The addition of an activating agent to the molten alloy prior to atomization with an inert gas, such as argon, serves to substantially reduce the porosity of metal powders. Suitable activating agents are characterized by an ability to rapidly diffuse to the surface of a molten metal particle and an affinity for oxygen. Activating agents that are useful for high nickel alloys and highly alloyed steels include magnesium, calcium, lithium, silicon, and rare earths.
    Type: Grant
    Filed: June 3, 1976
    Date of Patent: September 13, 1977
    Assignee: The International Nickel Company, Inc.
    Inventors: Jay Michael Larson, Ian Sidney Rex Clark, Robert Cameron Gibson
  • Method of making prealloyed thermoplastic powder and consolidated article
    Patent number: 3976482
    Abstract: The invention is directed to a process for improving workability of prealloyed powders, particularly those of the superalloy type, in which powder is cold reduced by subjecting it to the compressive forces exerted by the rolls of a rolling mill, as a consequence of which strain energy is imparted to the powder.
    Type: Grant
    Filed: January 31, 1975
    Date of Patent: August 24, 1976
    Assignee: The International Nickel Company, Inc.
    Inventor: Jay Michael Larson
  • Thermoplastic prealloyed powder
    Patent number: 3930841
    Abstract: Prealloyed powders, particularly of compositions which are difficult to work by conventional means, are subjected to forces such that strain energy is imparted thereto by virtue of which the prealloyed powders manifest low flow stress and a high degree of thermoplasticity.
    Type: Grant
    Filed: June 10, 1974
    Date of Patent: January 6, 1976
    Assignee: The International Nickel Company, Inc.
    Inventors: Timothy Earl Volin, John Stanwood Benjamin, Jay Michael Larson, Robert Lacock Cairns
