Patent number: 8056479Abstract: Disclosed is a separation device of an ejector motor for a portable missile, capable of being separated from a missile without any additional separation devices after ejecting the missile. An ejection rocket motor and a separation device are integrally formed. Ejection is performed by a thrust generated while the ejection rocket motor is combusted, and separation is performed by cutting off shearing bolts with using a force generated from a separation cylinder when the combustion of the ejection rocket motor has been completed. This operation and configuration may minimize a weight and a space occupied by a general ejection and separation device in a missile system.Type: GrantFiled: March 30, 2010Date of Patent: November 15, 2011Assignee: Agency for Defense DevelopmentInventors: Hyo-Nam Lee, Jong-Yun Oh, Seong-Eun Kim

Patent number: 8046946Abstract: A device for counting shots fired by a firearm including a permanent magnet mounted to moving portion of the firearm and electrically coupled to a coil mounted on a relatively stationary portion of the firearm. Movement of the magnet relative to the coil induces an electromotive force within the coil. The induced electromotive force can be used increment a shot-count indictor and thereby record the number of shots fired by the firearm. The electromotive force can also be measured by a verification circuit to determine the strength of a shot and thereby verify whether a round was actually discharged by the firearm. In some embodiments, information regarding the number of shots discharged and the strength of the shots can be transmitted to an external device.Type: GrantFiled: January 10, 2007Date of Patent: November 1, 2011Assignee: Packer Engineering, Inc.Inventors: Kenneth F. Packer, Alan D. Wilks, Peter J. Schubert, Thomas E. Long

Patent number: 8038094Abstract: A hydraulic system for aircraft operating devices provides a secondary pressure source for direction and deceleration control in case of loss of pressure from a primary pressure source. The system includes multiple pressure accumulators that include a primary accumulator, which supplies pressurized fluid to a first actuator, and first and second secondary accumulators, which supply pressurized fluid to second and third actuators, respectively. If the primary accumulator is disabled, the first secondary accumulator will supply pressurized fluid to the first actuator. If the first secondary accumulator is disabled, the second secondary accumulator will supply pressurized fluid to the second actuator. By providing multiple, substantially independent accumulators, direction and deceleration control is maintained even in the event of loss of the primary accumulator.Type: GrantFiled: March 30, 2009Date of Patent: October 18, 2011Assignee: Honda Motor Co., Ltd.Inventor: Hiroki Oyama

Patent number: 8037822Abstract: A cost-effective solution is proposed to improve explosive transfer between booster and warhead that is compatible with the existing base of general purpose warheads and flexible to work with new warhead configurations. A booster lens is placed in the fuze well that concentrates the pressure wave to penetrate the fuze well with a peak pressure that exceeds the detonation threshold and detonate the warhead explosive. The booster lens can be configured to control the direction of the concentrated lobe to penetrate the fuze well where the barriers are low.Type: GrantFiled: January 6, 2011Date of Patent: October 18, 2011Assignee: Raytheon CompanyInventors: A.

Patent number: 8037633Abstract: A handguard used on a firearm with a barrel nut having tines spaced about the outer periphery. The handguard includes a tubular body in which the inner surface adjacent the proximal end has a diameter larger than an outer diameter of the barrel nut and smaller than a diameter defined by the outer tips of the tines. Grooves are defined in the inner surface and extend longitudinally from the proximal end toward the distal end. The grooves are spaced apart around the periphery so as to correspond with the tines on the barrel nut. The body further has a circumferentially extending channel in the inner surface, spaced from the proximal end so as to receive the tines therein with the barrel nut in the tightened position to allow limited rotation of the body around the barrel relative to the barrel nut until the tines are aligned behind lands between the grooves.Type: GrantFiled: February 20, 2009Date of Patent: October 18, 2011Inventor: Stephen P. Troy

Patent number: 8033224Abstract: The invention represents a novel system for controlling the yield of an explosive charge that enables the explosive yield to be selected or decreased from full-yield detonation incrementally down to low-yield detonation using a continuous linear shaped charge jet spiraled around the main charge explosive and deflagrating a selected portion of the main charge explosive. The spiral linear shaped charge jet initiation system activates and projects a liner in a radial direction across a diameter of the main charge explosive in a spiral around its axis at a preselected deflagration velocity toward a main-charge detonation shock front reducing the main charge explosive.Type: GrantFiled: March 24, 2009Date of Patent: October 11, 2011Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: John W.
