    Abstract: An apparatus for generating shock waves by means of a supersonic projectile to effect, for example, phase transformation of a substance. A hammer in a cylinder is accelerated by introduction of compressed air into the cylinder, whereby a plunger formed integrally with the hammer at one end thereof is thrust into a hydraulic pressure chamber filled with a liquid and disposed coaxially with the cylinder. Thereupon, a high hydraulic pressure is generated in a hydraulic pressure chamber, and this hydraulic pressure accelerates a piston in a piston chamber connected with the hydraulic pressure chamber. The piston in turn compresses a light gas adiabatically to a high pressure, and a projectile fitted at one end of a barrel is thrust forward under the force of this high-pressure gas. The projectile is accelerated in the barrel and impacted onto a workpiece placed at the other end of the barrel at a speed higher than the sound velocity in the workpiece, whereby shock waves are produced in the workpiece and the workpiece is compressed under a superhigh pressure and at a high temperature to undergo the desired transformation.

    Abstract: Industrial diamond powder is prepared from a mixture of graphite and a non-metallic material which is semi-transparent to thermal radiation by projecting a solid body against said mixture at a velocity which lies between the sonic wave propagation velocity of said graphite and said semi-transparent material. The shock collision provides the high pressure and temperature rise necessary for conversion of graphite to diamond and the semi-transparent material provides for sufficiently rapid cooling to prevent reversion of the formed diamond powder to graphite.

    Abstract: A device for artificially producing diamonds or other articles of substantial hardness by utilization of heat and pressure over an instantaneous time period. The device, which is designed to achieve the requisite heat and pressure by detonation in an implosive manner, consists of two mating hemispheric bodies having a centrally interior cavity of spherical configuration. The two bodies are adapted to be affixed to one another in a positive manner, such as by internal screw threads. The hollow hemispherical bodies, which may be of bronze or other relatively soft material, are suspended such as by nylon string, within a hollow plastic shell. An explosive material is positioned about the exterior surface of the shell in an even and uniform manner with a plurality of detonators operatively connected to the explosive at appropriately spaced positions. An ignition harness is connected to the detonators so that they may all be actuated in a simultaneous manner. The material which is to be transformed, such as graphite or other carbonaceous matter, is disposed in the cavity of the bodies and upon detonation of the explosive there is created extreme inwardly directed pressures and temperatures which transform the carbonaceous material into stable diamond.
