Abstract: A content distribution system may be provided for reviewing content such as video games, music, movies, or the like that may be shared by the system. The content distribution system may receive a credential from a user and authenticate the user based on the credential to permit access to the system. The content distribution system may also receive content generated by the user if the user may be authenticated. The content distribution system may provide the received content to a content evaluation entity, for example. The content distribution system may receive a review for the content from the content review entity and then may determine whether the content passes a review process based on the review, for example. The content distribution system may provide additional access to the content if the content passes the review process.

Abstract: Mechanisms are disclosed that allow for the communication between closed computing systems and other computing systems. Gaming consoles, for instance, can use the present mechanisms to communicate with PCs, especially when unsigned content is sent from the PCs to the gaming consoles. The disclosed communication mechanism can have multiple channels to send information (which may include code and/or data associated with the unsigned content) from the PCs to the gaming consoles. Such information may be distributed over several channels on the communication mechanism. For instance, the communication mechanism can first send a subset of a set of information from a computing system to a closed computing system. Then, depending on the closed system resources, the remaining set of information can be sent to the closed system.

Abstract: Mechanisms are disclosed that allow for execution of unsigned content and the securing of resources in a closed system when such unsigned content is executing on the system. For example, an access layer is used between an operating system layer of the closed system and the actual unsigned content. This access layer may contain various sub-layers, such as a graphics layer, an audio layer, an input layer, and a storage layer. These layers can control access that the unsigned content can have to the native operating system layers and the associated resources of the closed system. By providing such an access layer, unsigned content, e.g., video games, can run on the closed system that is typically designed to run only signed content.

Abstract: An explosive projectile has a splinter-generating body inside which is placed an explosive and/or incendiary load ignited by a primer. The projectile also contains an intermediate charge placed between the primer and the explosive load. The charge is composed of a mixture of an explosive and a first pyrotechnic composition including at least one oxidizing agent and at least one reducing agent. The explosive projectile may be utilized as a medium caliber projectile ignited upon impact by a pyrotechnic fuse.

Abstract: A safety device to lock a firing pin of a spin-stabilized projectile fuse includes a flexible strip and a spiral spring. The flexible strip is disposed around the firing pin and has a first end, a second end and a length. The flexible strip is made of an elastic material. The spiral spring is windable around the flexible strip in a safe position and is disposed to unwind under centrifugal force to a firing position. The spiral spring is made of a spring strip that is wound around itself. When the spiral spring unwinds, the flexible strip unwinds within the spiral spring without exerting an elastic return force toward the firing pin. The length of the flexible strip is dimensioned such that the first end is offset in a circumferential direction relative to the second end by an offset amount when the flexible strip presses against the spiral spring in the firing position. As a result, the spin-stabilized projectile fuse functions reliably.

Abstract: The invention relates to a projectile comprising a shell body containing an explosive charge and a ballistic nose cone in which a trigger system is disposed. The ballistic nose cone is organized as two distinct parts which are connected together in axial alignment, comprising a bottom portion that is essentially rigid and a top portion that is essentially deformable on impact on a target. Each of the portions is charged with a compressed incendiary composition, and together they form a closed functional cavity whose shape is maintained on firing and during the trajectory of the projectile. The bottom portion also receives a layer of mechanically strong pyrophoric material, said material being set off by the charge in the ballistic nose cone which is itself set off on impact by the sudden increase in the pressure of the air contained in the closed functional cavity.

Abstract: Process for protecting against oxidation and/or nitridation of a liquid metal stream flowing from the outlet orifice of a ladle or a distribution vessel, comprising surrounding the pouring stream with a tube substantially throughout the height of the stream and injecting a protective gas at least around the pouring stream so as to minimize the contact of the molten metal with the ambient air and avoid the dilution of the protective gas and the aspiration of ambient air. A device for carrying out the process includes two complementary semi-shells for surrounding the pouring stream and a hinge articulating the semi-shells for opening and closing the latter.

Abstract: A method and apparatus for bending thick metal tubes is disclosed and is characterized in that thermal insulation is disposed inside the heated zone of the tube being bent, and that the thickness of said thermal insulation is great enough to considerably reduce the temperature gradient between the inside and outside surfaces of the tube in said heated zone.

Abstract: The present invention concerns a process and an arrangement for manufacturing a smoke emitting arrangement which generates a trace of smoke of predetermined color, red or other color, particularly adapted for use with a spin-stabilized projectile forming a distress or signal flare, and the colored smoke emitting arrangement obtained thereby. The process is characterized in that one obtains a smoke emitting composition by dry-mixing in a pulverulent state a sublimable coloring medium and a pyrotechnic carrier support composition; by distributing the coloring medium between the particles of the carrier support composition; and then placing the end-product (charge), so obtained, into a rigid, fluid-tight housing, which has an opening forming a nozzle oriented along an average predetermined direction, and by compressing the charge in in the interior of this housing in such a way that it is least compressed in the proximity of the nozzle.

Abstract: The security device of the invention comprises a movable organ in the interior of a cage mounted for rotation with respect to the body of a projectile, the movable organ being temporarily blocked from such rotation around the axis of gyration by at least one pin ejectable under the action of centrifugal force. Said pin is itself retained by an elastic spiral band enrolled upon the cage and which, as a result of a difference introduced into the speeds of respective rotation of the cage and of the body around the axis of gyration upon the exit of the projectile from the muzzle of the weapon, unwinds to liberate the pin. As a result, the movable organ after a trajectory of many tens of meters after the projectile has left the muzzle of the barrel of the weapon completes the pyrotechnic train which fires the projectile.

Abstract: This invention relates to the protection of the teeming flow or stream of molten metal contained in a vessel and passing through a plate-type valve or cut-off device of the kind comprising a stationary plate and a displaceable plate that is provided with at least one output nozzle. A gas which is substantially inert with respect to the metal and has a pressure slightly higher than atmospheric pressure is fed into the aforesaid device, and this gas surrounds the metal while the latter passes through the said device, in such manner as to isolate the same from the ambient air by an uninterrupted protective gaseous barrier.

Abstract: A method of bending a long metal member of constant cross-section by locally heating a narrow zone on the periphery of said member by means of a heating collar (5) which surrounds said zone, by exerting thrust (2) on one end of the member and by supporting its other end by means of a pivoting arm (3). The temperature of the heated zone on the periphery of the member is kept substantially constant by detecting the temperature of this zone or the size of the gap which separates the heating collar from the periphery of said zone at at least two points around said periphery, one of these points being nearest the center of curvature and the other being on the opposite side to the first.

Abstract: A method and apparatus for the heat treatment of industrial wastes wherein at least some of the constituent materials of the wastes are subjected to combustion and/or to pyrolysis to produce flue gases and, in some applications, a residue. The supply of an oxygenated combustion-supporting gas to the wastes is regulated as a function of at least one sensed predetermined characteristic of the flue gases. The oxygenated gas may be a mixture of air and substantially pure oxygen, the feed rate of one or both of these being regulated in response to the sensed temperature and/or oxygen content of the flue gases. Such regulation maintains the oxygen content of the flue gases within the range of from 0 to 7%; and the temperature of the flue gases may be maintained from 400.degree. to 1200.degree. C. and, preferably within a range of 50.degree. C. in this region.
