US Patent:

7311068, Dec 25, 2007

Filed:

Aug 21, 2006

Appl. No.:

11/507419

Inventors:

Jason Stewart Jackson - Roswell GA, US

International Classification:

F01L 1/28

US Classification:

123 79C, 1231882

Abstract:

One embodiment of the present invention provides a poppet valve offering an increased valve area, comprising an outer valve head having an outer valve port and an inner valve head having an inner valve port. The inner valve head is rotatable relative to the outer valve head to align the inner and outer valve ports, thereby increasing the effective valve area of the poppet valve. The path created by aligning the inner and outer valve ports can be designed to mix air flowing through the poppet valve. Another embodiment of the present invention provides a valve guide containing a poppet valve having a guide pin, wherein the guide pin rests within a groove in the valve guide. As the poppet valve moves through the valve guide, the groove controls movement of the guide pin and causes the poppet valve to rotate relative to the valve guide.

Inventors:

Jason Stewart Jackson - Atlanta GA, US

International Classification:

F01L 1/32

US Classification:

123 9028, 123 79 C, 1231882

Abstract:

One embodiment of the present invention provides a poppet valve offering an increased valve area, comprising an outer valve head comprising an outer valve port and an inner valve head comprising an inner valve port. The inner valve head is rotatable relative to the outer valve head to align the inner and outer valve ports to open a path through the poppet valve, thereby increasing the effective valve area of the poppet valve. The path created by aligning the inner and outer valve ports can be designed to mix air flowing into a combustion chamber.

Appl. No.:

12/348189

Inventors:

Jason Stewart Jackson - Atlanta GA, US

International Classification:

F42B 30/02
F42B 12/74
F42B 12/34

US Classification:

102517, 102510, 102501

Abstract:

A projectile is provided comprising a body with a channel that contains a non-Newtonian fluid. In various embodiments a plunger is located in the channel, wherein the plunger transmits a force to the non-Newtonian fluid upon interacting with a target, causing the non-Newtonian fluid to exert a pressure in the channel, and wherein the viscosity of the non-Newtonian fluid changes upon interacting with the target. By way of non-limiting example, the non-Newtonian fluid of embodiments of the present invention can comprise a shear-thickening fluid that increases its viscosity with at least the rate of shear upon interacting with the target.

Appl. No.:

12/902142

Inventors:

Jason Stewart Jackson - Atlanta GA, US

International Classification:

F41A 5/24

US Classification:

89193

Abstract:

The embodiments of the present invention generally provide or relate to an operating rod for use in an auto-loading firearm. More specifically, embodiments of the present invention provide an operating rod for selectively actuating a bolt carrier by gas-impingement or mechanical operation. The operating rod can comprise an operating rod gas duct coupled to an operating rod gas tube, wherein gases from a fired cartridge are directed into the gas duct and flow through the gas tube to actuate a bolt carrier by gas-impingement. Alternatively, gases from a fired cartridge can be directed against a forward-end of the operating rod, thereby causing the operating rod to mechanically operate the bolt carrier.
