Abstract: A method is disclosed for producing a dimensionally stable UO.sub.2 fuel pellet of large grain mole %, and relatively large pore size. A dopant containing an element selected from the group consisting of aluminum, calcium, magnesium, titanium, zirconium, vanadium, niobium, and mixtures thereof is added to a highly sinterable UO.sub.2 powder, which is a UO.sub.2 powder that is sinterable to at least 97% theoretical density at 1600.degree. C. in one hour, and the UO.sub.2 powder can then be formed into fuel pellets. Alternatively, the dopant can be added at a step in the process of producing ammonium diuranate. The ammonium diuranate is collected with about 0.05 to about 1.7 mole%, based on UO.sub.2, of a compound containing said element. That mixture is then calcined to produce UO.sub.2 and the UO.sub.2 is formed into a fuel pellet. The addition of the dopant can also be made at the hydrolysis stage in the manufacture of UO.sub.2 by a dry conversion process.

Two jaws are mounted in the first groove on diametrically opposite sides of the bore, the third jaw is mounted in the third groove and the second groove is provided for translating a cartridge case to have the lips of the three jaws extend into the case cannelure.

Abstract: This specification discloses a means for providing a barrier against the passage of fire through that portion of a wall aperture surrounding an electrical conduit, pipe, or the like. This is accomplished by placing a sleeve around that portion of the conduit passing through the wall, which sleeve is the central portion of an envelope which is anchored peripherally to the wall or to a more or less rigid material blocking the aperture through the wall and which sleeve connects to end portions of the envelope, each of which end portions extends to connect with the conduit on an opposite side of the wall. The annular region between the conduit and the surrounding envelope is filled with an intumescent gel. The boot is flexible and capable of some movement to compensate for thermal expansion, vibration or other forces during the life of the installation.

Abstract: Polynorbornene has been found to be an excellent binder for the preparation of solid fuel materials and solid propellants. Mixtures of polynorbornene with liquid fuel materials such as kerosene, gasoline, or the advanced missile and aircraft liquid fuels such as JP-4, JP-5, JP-9, JP-10, RJ-4, and RJ-5, for example, can contain 80% or more of the liquid fuel material and still exist in the form of a tough rubbery polymer which has excellent burning characteristics as a solid fuel for a ramjet. Many of these materials can be tailored to have heats of combustion higher than the state-of-the-art solid ramjet fuel formulations.

Abstract: The present invention relates to cast-loading of explosive charge compositions comprising at least two explosive components for cast-loading of a plurality of moulds or shell bodies (6) in a closed transportable unit (1). The moulds or shell bodies (6) are preheated to a predetermined temperature essentially corresponding to the melting temperature of the explosive charge composition. With the predetermined temperature substantially maintained the moulds or shell bodies (6) are filled with the liquid explosive charge composition after which a vibration movement of a specific frequency is imparted on the filled moulds or shell bodies by means of ball vibrators (24). Heavy particles of the explosive charge composition sink to the lower parts of the moulds or shell bodies. After a predetermined time period for sedimentation the filled and vibrated moulds or shell bodies are then cooled to a low temperature for solidification of the charges.

Abstract: A powder measuring device for use in connection with reloading cartridges has a powder transfer member supported for translating or, alternatively, rotating between a position where at least one cavity in the member is filled with powder from a hopper to another position wherein the powder is discharged through a tube to an empty cartridge. A cartridge to be reloaded is driven upwardly by a manually operated ram. The force for actuating the mechanism that drives the transport member is transmitted through the cartridge which means that unless a cartridge is positioned on the ram for receiving the powder the transport member will not be moved in response to operation of the ram and unintended discharge of powder will be prevented.
