    Abstract: A method and apparatus for fabricating high density monolithic metal and oy billets. The process requires preheating precursor materials of metal or alloy billets by means of a combustion synthesis called Self-Propagating High-Temperature Synthesis (SHS). The reaction takes place in an insulated reaction vessel where the precursors, in a powder form, are heated to high temperatures. The precursors are then compacted to high density by means of pressure waves generated by detonation of an explosive. The method is capable of producing high purity tungsten and tungsten-based alloys of greater than 90% theoretical density.

    Abstract: A pulse detonation engine is provided with several detonation combustors selectively coupled to an air inlet and fuel source by a rotary valve. The rotary valve isolates the steady operation of the air inlet and fuel system from the unsteady nature of the detonation process, and allows the fueling of some of the detonation chambers while detonation occurs in other detonation chambers. The fuel system may use a solid fueled gas generator.

    Abstract: High-pressure high-temperature device for conversion the graphite to diamonds (DCGD) includes a container having a high pressure chamber, an inlet for introducing a fuel, an oxidizer and an electrolyte respectively into container, a generator of instantaneous electro-impulses, electrodes secured to the container and connected with the generator of instantaneous electro-impulses to produce the power electro-discharge between electrodes. DCGD includes a source of a direct electro-current and a pair of positive and negative electrodes positioned within an electrolyte for heating the graphite in the high pressure chamber. The high-pressure chamber includes a cylinder-piston unit submerged within an electrolyte. The piston of cylinder-piston unit is explosively driven toward the high-pressure chamber by the combined action of electro-discharge in the electrolyte a combustion of fuel inside of container. DCGD may be adapted for compaction other materials, for extruding, forging and the like. DCGD may be used also to provide coating, molding and hardening work pieces which must be placed in the container.

    Abstract: A method of controlling inlet valves of a compression reactor consists in that in the process of operation of the reactor 1 pressure in its working spaces 4, 5 and supply lines 7, 6 is continuously measured, the sign of a pressure differential (.DELTA.P) between said working spaces 4, 5 and the respective supply lines 7, 6 is determined, at the instant the sign of the pressure differential (.DELTA.P) changes from "minus" to "plus" a command to relieve the inlet valves 8, 9 of all control actions, except the pressure differential, is produced, and at the instant the sign of the pressure differential (.DELTA.P) changes from "plus" to "minus" a command to read a preset time interval (.tau.) is supplied, at the expiration of which interval a command to close the inlet valves 8, 9 of the reactor 1 is produced. A device for controlling inlet valves of a compression reactor comprises drives 10, 11 actuating the inlet valves 8, 9 of the reactor 1, pressure pickups 14, 15, 16, 17 arranged in the working spaces 4, 5 and in the supply lines 6, 7, comparators 18, 19 connected to the outputs of the pickups 14, 15, 16, 17, units 12, 13 to control the drives 10, 11, the inputs of which are connected through time relays 20, 21 to the outputs of the comparators 18, 19 and the outputs of which are connected to the drives 10, 11, and a chronometer 22 connected with one of the comparators 18, 19.
