Patent number: 10410756Abstract: A container for storing and/or transporting spent nuclear fuel. The container includes a body that defines an internal cavity that holds the spent nuclear fuel and an outer surface. The outer surface has holes formed therein into which trunnions are positioned. The container can be lifted by a lift yoke by coupling the lift yoke to the trunnions. The trunnions may include first and second components such that the first component is slidable in its axial direction relative to the second component when a force that exceeds a threshold acts on the second component. Thus, the second component may be slidable between a protruded state in which a portion of the second component protrudes from the outer surface of the body and a retracted state in which the second component does not protrude from the outer surface of the body.Type: GrantFiled: June 30, 2017Date of Patent: September 10, 2019Inventor: Krishna P.

Patent number: 8746355Abstract: A fire-extinguishing bomb that can be pre-programmed to explode 2-200 feet above the ground or tree line. The bomb employs a laser or barometric altitude sensor in combination with a GPS-altitude sensor for failsafe detonation with extreme accuracy at the proper altitude. The redundant failsafe altitude-dependent detonation system ruptures a container carrying a payload of wet or dry fire retardant/suppressant, preferably dry environmentally-friendly fire-retardant powder having no toxicity and having fertilizer properties. Upon detonation the device coats the ground below with a uniform fire extinguishing coating. The core components of the bomb can be biodegradable, or alternatively can be readily retrieved and reused after each activation, thereby increasing both economy and reducing environmental concerns.Type: GrantFiled: December 2, 2011Date of Patent: June 10, 2014Inventor: Christopher Joseph Demmitt

Patent number: 8076623Abstract: A spin-stabilized projectile is steered by taking air from an air intake at the front of the projectile, and expelling the air along an outer surface of the projectile to alter its trajectory toward the desired impact location. Air taken in through the air intake is directed toward a rotor that is able to rotate relative to the rest of the projectile. The rotor has an outlet that may direct the air taken in at the air inlet out in a direction having both radial and circumferential components. The force produced in the radial direction provides a steering force substantially normal to the projectile axis, used to steer the projectile. The force produced in the circumferential direction is used to provide impetus to spin the rotor. A brake is used to control the rotational speed of the rotor, to control the direction that the air is expelled from the projectile.Type: GrantFiled: March 17, 2009Date of Patent: December 13, 2011Assignee: Raytheon CompanyInventor: Richard L.

Patent number: 7795565Abstract: A guided missile or projectile and associated guidance control are provided to control a path to a point of intersection with a potentially moving target. A new path is repetitively recomputed and acceleration orthogonal to the path is applied to minimize heading error and thereby to converge on the target. The gain of the control function is partly proportional to heading error, but the gain is reduced approaching the point of convergence. In this way, the guidance control is more responsive to actual variance of the true heading error and is less responsive to random error in sensing the target heading, which random error would otherwise increase in its contribution to corrective guidance movements approaching the point of intersection.Type: GrantFiled: January 3, 2008Date of Patent: September 14, 2010Assignee: Lockheed Martin CorporationInventor: Gregory F.

Patent number: 5109774Abstract: Disclosed is a new type of penetrating projectile, the penetrating capacity of which is improved and more efficiently controlled, notably through a solution to the problems of obliquity. A projectile of this type has a front element forming the active part, fixedly joined to a tube. The tube has a closed end which contains a propellant charge for the propulsion of the element and an igniter for the charge, responding to the impact of the element on a target. In reaching the target, the projectile penetrates it slightly under the effect of the velocity and it is only at this instant, or slightly after it, that the penetration proper takes place. The penetration thus takes place without obliquity. This projectile can be used as an individual munition or sub-munition.Type: GrantFiled: May 14, 1991Date of Patent: May 5, 1992Assignee: Thomson-Brandt ArmementsInventor: Jean Deffayet

Patent number: 5056408Abstract: A self-retracting bomb suspension lug assembly for being releasably supported by a hook or the like of an airplane bomb rack. The lug is mounted within a housing for axial movement and has an outer surface conforming to the shape of the bomb so as to eliminate aerodynamic drag when the bomb is released. Springs, such as a stack of Belleville springs, are disposed for biasing the lug inward when the bomb is released and the weight of the bomb no longer bears on the lug. Finger springs and pawls engagable with a groove in the bottom surface of the lug are provided to maintain the lug in partially extended loading position wherein the top of the lug is accessible for being grasped. To cock the lug, it is moved slightly inward against the force of the lug biasing spring, and the finger springs are forced radially inward to engage the groove.Type: GrantFiled: July 31, 1990Date of Patent: October 15, 1991Assignee: TechTeam, Inc.Inventors: Bruno Joner, John W.

Patent number: 5042744Abstract: A guideable sonobuoy is disclosed that is ejected from a moving aircraft o the free stream with a ring wing opened to guide the buoy along a predetermined flight path. While the buoy remains packed inside a launch container, the ring wing, made of spring steel, is collapsed around the nose portion thereof. Once launched, the ring wing will fly the buoy to a predetermined destination.Type: GrantFiled: August 30, 1990Date of Patent: August 27, 1991Assignee: The United States of America as represented by the Secretary of the NavyInventors: Bruce W. Travor, James F. McEachern, Frank P. Marshall

Patent number: 4981079Abstract: The disclosed projectile has a tube forming a mortar, a munition contained in the tube, at least three deployable fins, solidly joined to the tube, and firing means triggering the ejection of the munition. During operation, when the projectile, released from an aircraft, lands on the ground for example, the fins form a pedestal in the mortar tube and, upon the command of the firing means, the munition is ejected to a certain distance from the tube.Type: GrantFiled: September 5, 1989Date of Patent: January 1, 1991Assignee: Thomson-Brandt ArmementsInventor: Andre Winaver

Patent number: 4674407Abstract: A bomb to bombrack attachment lug assembly engages in a keyhold slot of a actice bomb casing and includes a metal lug element and a plastic locator element that centers and releasably locks the assembly in the keyhold slot. The lug element has an eye portion, a stem and arms extending laterally from the stem, while the locator element includes a cylindrical body snapped onto the stem and arms and has laterally extending ears having retaining bosses that engage the slot.Type: GrantFiled: June 2, 1986Date of Patent: June 23, 1987Assignee: The United States of America as represented by the Secretary of the NavyInventors: John G. Seubert, Kevin G. Beasly, Stanley J. Herold, John E. Laswell

Patent number: 4637313Abstract: A terra-finned earth penetrator having a plurality of axially symmetric fins adapted to rotate in a downward direction in response to off-axis inertial reactive forces generated on impact with earth. The penetrator thereby executes a tuck maneuver within the earth surface thereby avoiding ricochet, broaching or upward turning found in low level weapon delivery systems.Type: GrantFiled: December 31, 1984Date of Patent: January 20, 1987Assignee: Avco CorporationInventors: David Henderson, James A. Hollowell, Howard A. Woodbury

Patent number: 4505203Abstract: In combination: an elongated container comprising a plurality of explosively separable parts extending rearwardly from a closed forward end; a load in the rearward end of said container; and a frangible, unitary ballast member in the container between the closed end and the load.Type: GrantFiled: February 4, 1983Date of Patent: March 19, 1985Assignee: Honeywell Inc.Inventors: D. Ward Brady, James F. Chapman
