Patents by Inventor Richard P. Blakemore

Richard P. Blakemore 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).

  • Culture medium and conditions for growth of magnetic bacteria
    Patent number: 4452896
    Abstract: A biologically pure culture of a bacterium of the genus Aquaspirillum, designated MS-1, has been found to contain chains (so-called magnetosomes) of single domain magnetite particles. The magnetite particles are roughly cubic and are about 500 .ANG. on a side. Each of the chains contains approximately 20 magnetite particles. These magnetite particles can be recovered from the bacterium and usefully employed in magnetic recording devices and the like. The biologically pure culture of the magnetic bacterium may be grown in a low oxygen environment and on a nutrient medium containing ferric quinate.
    Type: Grant
    Filed: April 22, 1983
    Date of Patent: June 5, 1984

  • Magnetic bacteria and products derived therefrom
    Patent number: 4385119
    Abstract: A biologically pure culture of a bacterium of the genus Aquaspirillum, designated MS-1, has been found to contain chains (so-called magnetosomes) of single domain magnetite particles. The magnetite particles are roughly cubic and are about 500 A on a side and each of the chains contains approximately 290 magnetite particles. These magnetite particles can be recovered from the bacterium and usefully employed in magnetic recording devices and the like.
