  • Tampable chub cartridge
    Patent number: 4052939
    Abstract: A chub cartridge containing a water-bearing blasting agent and having a film wrap of a cross-laminate of oriented film layers has at least one unlaminated zone in the film wrap in the longitudinal direction, or preferably is adapted to form a zone of multiple delaminations along said direction by virtue of scoring, the latter being the site of delamination when the cartridge has end-pressure applied to it with a tamping rod. The different layers fail in different directions along the unlaminated zone, affording a measure of integrity to the cartridge if roughly handled, as well as ease of rupture on tamping. The cartridge also has good abrasion and tear resistance, and dimensional stability.

  • Heat dissipation system
    Patent number: 4051892
    Abstract: A heat dissipation system for removing the decay heat from a nuclear reactor after a failure in the main coolant system. The heat dissipation system provides a fluid circulation conduit in which a condensible fluid is circulated. Heat removed from the circulating fluid is utilized to vaporize condensate and thereby power a jet circulator that provides the motive force for continued fluid circulation. A heat exchanger in the fluid circulation conduit removes and rejects heat from the circulating fluid to continuously remove and reject heat from the system.

  • Method of operating a nuclear-power-generating installation with closed gas cycle and plant operated by this method
    Patent number: 4052260
    Abstract: A nuclear power-generating installation comprises three power-generating bines which are operated by three partial gas streams heated in separate passages of a nuclear reactor. After traversing the power-generating turbines the partial gas streams are cooled in respective recuperative heat exchangers to recover residual useful heat therefrom and are combined into a lesser number of gas streams each of which is subjected to at least two compression stages with at least one intervening cooling stage in which all of the gas is combined to flow as a total gas stream through at least one such cooler. Following the last compression stage the gas is again subdivided into three partial streams for preheating in the aforementioned recuperative heat exchangers before traversing the nuclear reactor for the main heating.

  • Hydraulic-powered device
    Patent number: 4047595
    Abstract: In a first embodiment an improved, hydraulic-powered paving breaker is depicted in which a novel arrangement is provided for internally lubricating the breaker. In the arrangement an elbow taps off discharging pressured hydraulic fluid from the breaker and, through a manifold line coupled to fittings, which are in penetration of the housing of the breaker, admits hydraulic fluid into the breaker to lubricate a reciprocating plunger, moil, and O-ring seals. In an alternative embodiment, a conduit is formed entirely within the breaker for the same purpose. In both embodiments a restrictor device is interposed between the supply of pressured hydraulic fluid and the points of fluid injection to insure a uniform supply of fluid to the latter at a given prescribed pressure.

  • Sealed sabot projectile
    Patent number: 4043269
    Abstract: A sealed sabot projectile wherein the rear centering ring of the sabot has n opening to expose the projectile tracer material to the propulsion gases. This opening has a seal over it with a small aperture therein for controlled flow of gases to ignite the tracer material yet avoid premature separation of the projectile from the rear spin generating portion of the sabot. The resulting greater spin velocity of the projectile gives it greater accuracy.

  • Container construction for an ejectable ballistic payload
    Patent number: 4043268
    Abstract: A segmented ejectable payload container is arranged to provide improved protection against axial separation of its segments during the firing operation. The container is formed as a hollow shell, with its outer jacket formed integral with a bottom end plate whose outer surface is recessed to receive an outwardly extending flange of an inner container jacket. The other end of the opposed jackets is removably closed by means of a threaded end plate. A second flange on the inner jacket is received in a corresponding recess of the second end plate when such end plate is in operative position. The interfaces between the flanges on the inner jackets and the recesses in the respective end plates are closed by means of a radially disposed seal. The depth of such recesses is chosen so that the outer surface of each end plate projects beyond the adjacent surface of the associated flange.
