Walter W. Wharton 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).

  • Liquid monopropellant compositions including hydrazine and methoxylamine hydrochloride
    Patent number: 3953261
    Abstract: The use of methoxylamine hydrochloride (CH.sub.3 ONH.sub.2. HCl) as an adive to exothermally decomposing liquid monopropellants such as hydrazine and hydrazine water mixtures to lower the freezing point of the monopropellants and thereby render the monopropellants usable in gas generators at very low temperatures.
    Type: Grant
    Filed: June 18, 1969
    Date of Patent: April 27, 1976
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: William A. Duncan, John F. Phillips, James A. Murfree, Jr., Walter W. Wharton
  • Monopropellant composition comprising hydrazine and methoxylamine nitrate
    Patent number: 3953262
    Abstract: The use of methoxylamine nitrate (CH.sub.3 ONH.sub.2.NHO.sub.3) as an addve to exothermally decomposing liquid monopropellants such as hydrazine and hydrazine water mixtures to lower the freezing points of the monopropellants and thereby render the monopropellants usable in gas generators at very low temperatures.
    Type: Grant
    Filed: November 20, 1969
    Date of Patent: April 27, 1976
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: William A. Duncan, James A. Murfree, Jr., Pasquale Martignoni, Walter W. Wharton, John F. Phillips
  • Energetic liquid monopropellant compositions containing hydrazine and methoxylamine perchlorate
    Patent number: 3941626
    Abstract: The use of methoxylamine perchlorate (CH.sub.3 ONH.sub.2.HClO.sub.4) as an dditive to exothermally decomposing liquid monopropellants such as hydrazine and hydrazine water mixtures to maintain energetic monopropellants and at the same time lower the freezing point of the monopropellants, thereby rendering the monopropellants usable in gas generators at very low temperatures.
