Abstract: A system receives content of a memory resource. The system compares the content of the memory resource with a first resource data associated with a first physical space, and with a second resource data associated with a second physical space. The system determines which of the first physical space and the second physical space can fulfill more than a threshold percentage of objects in the memory resource based on the comparison between the content of the memory resource with the first and second resource data. The system determines that the first physical space can fulfill more than the threshold percentage of objects in the memory resource. The system assigns the first physical space to the memory resource for concluding an operation associated with the memory resource.

Abstract: A system presents, on a user interface, a first message that indicates an operation associates with a memory resource is concluded. The system present, on the user interface, content of the memory resource that comprises a plurality of objects. The system presents, on the user interface, a set of instructions to prepare the plurality of objects in a particular sequence. The system receives a second message that indicates the plurality of objects in ready for pickup by a delivery mechanism. The system presents, on the user interface, an alert message that indicates the delivery mechanism has reached a pickup location coordinate. If the category of the delivery mechanism is an autonomous delivery mechanism, the system presents, on the user interface, a pin number that unlocks the autonomous delivery mechanism.

Abstract: A liquid propellant tank of the rolling bonded diaphragm type used for missile propulsion systems contains a flexible piston that is formed together with the outer tank diaphragm in a unitary one piece assembly.

Abstract: A method and apparatus for combusting solid fuel by introducing a mixture of fuel particles and carrier fluid into a reaction chamber near the center of one end of a combustion chamber and injecting oxidizer gas tangentially into the chamber to establish a swirling flow of gas, fuel particles, and combustion products within a region adjacent the chamber walls. The mass flow rates of oxidizer gas and fuel are regulated to maintain a relatively oxygen-rich stoichiometry within an annular region and a relatively fuel-rich stoichiometry within a central region, and to cause flow of the oxidizer gas and combustion products thru the reaction chamber with throughput residence times of the order of a few hundred milliseconds. This combination of a fuel-rich core portion and a relatively oxygen-rich annular zone effects oxidation of most of the carbon content of the fuel before it reaches the walls and avoids reduction of metal compounds in the fuel, all without overall excess-air combustion.

Abstract: An apparatus and method for combusting carbonaceous fuels includes a reaction chamber defining a reaction zone and means for injecting fuel and oxidizer gas in a manner to produce in the reaction zone a wheel-type flow of the fuel-gas mixture. In preferred embodiments, the high velocity wheel-type flow operates to suspend fuel or other reactant particles in the swirling gas for residence times required for substantially complete reaction of the particles prior to the particles impinging against the walls of the reaction chamber. High angular veocities and the resulting centrifugal forces operate to remove substantially all slag from the gas as it approaches the downstream end of the reaction chamber. Operating temperatures are maintained at a level to avoid excessive volatilization of slag and thereby promote separation of liquid slag from the gaseous reaction products.
