  • Obtaining heteropolysaccharide-producing microorganism and the microorganism agrobacterium radiobacter NCIB 40018
    Patent number: 5125099
    Abstract: The invention provides a process for obtaining a second micro-organism by derivation from a first micro-organism, each micro-organism having the capability of producing an extra-cellular product when grown in the presence of a carbon-containing substrate, and the substrate uptake system of the first micro-organism being limiting for the production of the extra-cellular product, which comprises the steps of growing the first micro-organism under glucose limitation, and isolating the second micro-organism in which the glucose uptake system is at least partially derepressed, which process may further comprise the additional steps of growing the isolated second micro-organism and recovering the extra-cellular product; Agrobacterium radiobacter NCIB 40018, and its use for preparing a heteropolysaccharide.
    Type: Grant
    Filed: May 12, 1989
    Date of Patent: June 23, 1992
    Assignee: Shell Internationale Research Maatschappij B.V.
    Inventors: Alexander Cornish, Jacqueline A. Greenwood, John D. Linton, Colin W. Jones
  • Process for preparing a heteropolysaccharide, heteropolysaccharide obtained thereby, its use, and strain NCIB 11883
    Patent number: 4634667
    Abstract: Process for preparing a heteropolysaccharide from strain NCIB 11883 and use of the latter e.g. as viscosity modifier in an aqueous system such as completion fluids, work over fluids, stimulation fluids, and preferably in drilling fluids and use in connection with well-treatments, and enhanced oil recovery.
    Type: Grant
    Filed: September 24, 1984
    Date of Patent: January 6, 1987
    Assignee: Shell Oil Company
    Inventors: John D. Linton, Michael W. Evans, Andrew R. Godley
  • Weapon recoil simulator
    Patent number: 4079525
    Abstract: An apparatus for simulating the recoil force of a weapon A recoil force generator is coupled through a linkage to the weapon in such a manner that the recoil force is substantially coaxial with the axis of the weapon over wide variations in weapon aiming positions. The simulated recoil force is also used to provide simulation of weapon recocking, round counting and empty weapon simulation.

    Date of Patent: March 21, 1978
    Assignee: Spartanics, Ltd.
    Inventors: John D. Linton, Samuel P. Willits, William L. Mohan
  • Weapon training simulator
    Patent number: 4065860
    Abstract: An apparatus for automatically determining without human intervention the intersection point of the axis of an aimable optical system with a plane. A scanning radiation source is imaged on a radiation sensor array by a movable focusing reflector. The signal output from the sensor array is electronically processed to determine the intersection point of the optical axis of the focusing reflector on a target plane. When the apparatus is used as a weapon training simulator, a shot sound synthesizer imparts additional realism.
