Filed:

Aug 20, 2007

Appl. No.:

11/894063

Inventors:

James Alfred Dunnam - Austin TX, US
Mauricio F. Quintana - The Woodlands TX, US

International Classification:

F42B 12/38

US Classification:

102458

Abstract:

A ballistic tracer platform for use with a shotgun shell to provide an aiming and training aid for shotgun shooting sports, which also can be used for military and police applications. The ballistic tracer platform emits light after ignition of the shell, providing the shooter with a consistent reference to make corrections to his aiming point and shooting techniques. The tracer platform can be used in ordinary shotgun shells. The tracer platform comprises a translucent, resilient, elastic, cylindrical container in which the reactants, a fluorescent colored dye and oxalate solution and an activator, are held, separated from each other prior to ignition by encasing one or both in its own glass bulb or tube. The blast from ignition of the shell causes the glass bulb(s) or tube(s) to break. The resulting chemiluminescent reaction between the reactants results in emission of light which is visible to the shooter.

International Classification:

F42B 7/02

US Classification:

102458, 102455

Abstract:

A tracer cylinder for use with a shotgun shell to provide an aiming and training aid for shotgun shooting sports, which also can be used for military and police applications. The tracer cylinder, which contains a liquid, has one or more openings, each one releasably closed with a valve. The tracer cylinder is loaded into a shotgun shell and fired. After the valve in the bottom of the cylinder is released, the liquid is extracted through the opening by physical forces, creating a long-lasting mist or fog cloud that is visible to the shooter. The shooter is provided with a consistent and durable reference, allowing him or her to make effective corrections to his or her shooting technique. The tracer cylinder can be loaded into a shot holder, with or without shot pellets.

International Classification:

F42B 7/02

US Classification:

102458, 102370

Abstract:

A tracer cylinder for use with a shotgun shell to provide an aiming and training aid for shotgun shooting sports, which also can be used for military and police applications. The tracer cylinder, which contains a liquid, is positioned in a shotgun shell above a disk-shaped piercing valve. The shell is loaded into a shotgun and fired. The forces of ignition cause the point on the piercing valve to puncture the bottom of the cylinder, and, when the cylinder is airborne, tracer liquid is released through the resulting opening by physical forces, creating a long-lasting mist or fog cloud that is visible to the shooter. The shooter is provided with a consistent and durable reference, allowing him or her to make effective corrections to his or her shooting technique. The tracer cylinder can be loaded into a shot holder, with or without shot pellets.

Inventors:

International Classification:

F42B007/02

US Classification:

102458000

Abstract:

A ballistic tracer platform for use with a shotgun shell to provide an aiming and training aid for shotgun shooting sports, which also can be used for military and police applications. The ballistic tracer platform carries a tracer element, which provides the shooter with a consistent reference to make corrections to his or her aiming point and shooting techniques. The ballistic tracer platform can be used in ordinary shotgun shells. The ballistic tracer platform consists of a cylindrical structure with a coaxial cylindrical cavity in which the tracer element is disposed. The tracer element can be composed of incendiary or non-incendiary materials. The ballistic tracer platform can be modified to improve its ballistic shape, such as modifying the shape of its nose. Mass can be added to cavities formed in the ballistic tracer platform in order to adjust the weight of the device. Grooves, fins, or orifices can be formed in surface of the device to create additional spin.

International Classification:

H02K 7/02

US Classification:

322 4

Abstract:

A rotating device for multi-megawatt, fast response frequency regulation for the electric grid. The device generally has a main shaft coupled to a motor-generator, a main spring concentric to the main shaft, and several radially-symmetric arms, each connected to the main spring via a four-bar mechanism. As the rotational speed of the device increases, centrifugal force acting on the arms causes them to rise, the four-bar mechanism compresses the main spring, and energy is stored in the device as a combination of kinetic rotational energy, elastic potential energy, and gravitational potential energy. The device can be configured with additional springs, which can be compression springs, tension springs, or a combination thereof, in order to increase the amount of energy produced. Symmetrically-spaced gliding masses can be arranged on the arms as well.
