Abstract: A work bench for firearms including a planar base from which a pair of spaced-apart, rigid sides upwardly project. Each side includes a top having a plurality of grooves. The grooves in each top form a symmetrical array. The sides are disposed oppositely from one another in substantially axial alignment and thus form a plurality of companion pairs of grooves adapted to mate with a firearm. A compliant material such as leather or the like is provided on the side tops and within the arrays and grooves, such that a fire arm may be nondestructively snugly urged into temporary fitting support within said grooves.

Abstract: A device for ejecting ammunition containers from a war head has, transversely to the war head longitudinal axis a bellows which accepts individual ammunition containers in concave circumferentially sparse pockets (6). The bellows is inflated by a gas-generator including a gas-permeable tube extending along the longitudinal axis. In order to achieve as wide a variation range of ejection behavior of the ammunition container as possible, the propellant charge of the gas generator is particulate and at least one ITLX ignition cord extends along the longitudinal axis of the tube, so that the hot particles during burndown of the ITLX ignition cord are pressed between the particles of the propellant charge (12). A damming serves to build up the initial pressure required for the burn-down of the propellant charge.

Abstract: A temperature compensating ballistic control tube system for varying the volume containing primary propellant, for the purpose of affecting the effect of the propellant on the projectile in order to compensate for the effect of ambient temperature upon the performance of the primary propellant. The volume containing the primary propellant is changed by pushing the projectile away from the casing containing the primary propellant, down a gun bore by a piston of the ballistic control tube. The piston, pushing the projectile, is moved by an ignited secondary charge in the ballistic control tube. Electronic components detect initial movement of the piston and projectile and, after a certain delay, ignite the primary propellant thereby ejecting the projectile from the gun. A typical primary propellant, within a given volume, is temperature senstive, that is, it provides more force to the projectile at higher temperatures.

Abstract: An improved basket structure for use within a nuclear fuel transportation cask is disclosed herein. The improved basket structure comprises an array of structurally independent rod-receiving cells formed from four individual side members wherein each member terminates into a flange of enlarged thickness along one of its lengthwise edges. The flange includes a slot that is complementary in shape to the free edge of other side members so that cells may be formed by interfitting the free edges of the side members with the complementary slots in the flanges. The flanges are thick enough so that the flanges of adjacent cells may be welded together with no appreciable warpage. When the basket is fully assembled, the flanges form spacing blocks between the adjacent cells which maintain subcriticality in the nuclear fuel contained therein.

Abstract: The invention provides an apparatus and method for diagnosing breached fuel elements in a nuclear reactor. A detection system measures the activity of isotopes from the cover-gas in the reactor. A data acquisition and processing system monitors the detection system and corrects for the effects of the cover-gas clean up system on the measured activity and further calculates the derivative cure of the corrected activity as a function of time. A plotting system graphs the derivative curve, which represents the instantaneous release rate of fission gas from a breached fuel element.

Abstract: A fail-safe electric actuator, for use with a control mechanism such as a valve, is disclosed. The actuator device eliminates the possibility of the control mechanism being locked in operative position by the interruption of electric power, by automatically and mechanically returning the control mechanism to its inopertive position as soon as current is cut off. This is accomplished by the release of a torsion spring, wound previously by the rotation of a fluid-driven vaned torque actuator in turning both the control-mechanism and the electric fail-safe actuator into operative position.
