  • Patent number: 10871358
    Abstract: An apparatus for processing incendiary capsules for the purpose of prescribed burning. The apparatus includes a reciprocating injector tube driven by a crankshaft and a reciprocating mechanical pump driven by a cam. In order to synchronize these reciprocating motions the crankshaft and cam are joined together as a single part. The incendiary spheres exit a hopper and line up in series in a tube which deposits them one by one into a nest. Each individual sphere is punctured in the nest by a needle then injected with reactant. Each sphere is then withdrawn from the nest and dropped through a discharge opening before the next incendiary in line is processed in the same manner.

  • Patent number: 10151560
    Abstract: An apparatus for launching incendiary spheres for prescribed burning is provided. This apparatus receives ‘charged’, or injected, spherical incendiaries, then launches them in a controlled direction at a controlled distance. The charged incendiaries are first emitted from a conventional Plastic Sphere Dispenser (PSD) into the intake of the apparatus whereupon they are moved along a lower pathway by a delivering wheel to a launching point relative to a spinning wheel or a plurality of spinning wheels. These spinning wheels convey velocity to each incendiary sphere, which is thereby launched in a trajectory that is determined by the azimuth of orientation, and the rotational velocity, of the spinning wheels.

  • Publication number: 20160265890
    Abstract: An apparatus for launching incendiary spheres for prescribed burning is provided. This apparatus receives ‘charged’, or injected, spherical plastic incendiaries, then launches them for a distance. The charged incendiaries are first emitted from a conventional Plastic Sphere Dispenser (PSD) into the intake of the apparatus whereupon they roll into a slotted basin, from which they are picked up individually immediately upon entry and carried by a delivering wheel to a juncture point'between a plurality of spinning wheels. These spinning wheels convey velocity to each incendiary sphere, which is thereby launched in a trajectory that is determined by the plane of orientation, and the rotational velocity, of the spinning wheels.

  • Patent number: 9199735
    Abstract: An apparatus for processing and dispensing incendiary capsules is provided. The apparatus includes a hollow tube which serves as a cylinder within which is located a reciprocal piston or a plurality of co-axially mounted pistons driven by a cam. When this coordinated cycle begins with the piston assembly in its full-down position, and the cam assembly is then rotated 360 degrees, the piston assembly will proceed to its full-up position and then back to its full-down position. During this cycle, the following occurs in order: (1) an incendiary is received and enclosed within the piston assembly, that incendiary is then (2) pierced by a needle, then (3) injected with reactant, then (4) the needle is withdrawn from the incendiary, and finally (5) the incendiary is expelled from the cylinder. The feeder is operatively connected with the cam-piston assembly and feeds each individual incendiary into the piston assembly.

  • Patent number: 7582730
    Abstract: Iron-regulated, outer membrane proteins found in Neisseria gonorrhoeae and Neisseria meningitidis are important in transferrin receptor function. The proteins, which are isolatable by means of a transferrin affinity column, bind specifically to antisera raised against an iron-regulated outer membrane protein having a molecular weight of approximately 100 kD found in Neisseria gonorrhoeae.

  • Patent number: 6887482
    Abstract: An isolated, antigenic polypeptide comprises a segment having at least fifty amino acid residues. The amino acid sequence of the segment is present in N. meningitidis, and is different from, but substantially homologous with, the amino acid sequence of a segment of a member of the hemolysin family of toxins.
