Abstract: Two similar coaxially arranged dies have cut an annular groove in each respective face thereof, facing the plunger of the associated press. The edges of this groove extend along imaginary circles of which the centre is the centre of the respective face. A plastic medium is placed intermediate of each plunger and the respective face of the dies, so that this medium adjoins the central portion of this face and overlies the respective groove along the entire length thereof, at least partly in crosssection. With the dies being of the herein disclosed structure, the stress gradient along the axis of symmetry of the dies is substantially reduced.

Abstract: Two dies interconnected along the periphery thereof are provided on their oppositely adjacent face surfaces with center recesses and ridges, the latter being disposed coaxially in relation to said recesses. When the dies are drawn together said recesses are adapted to form a high pressure chamber in which a container made of a thermal and electrical insulating material which is ductile under omnidirectional compression is enclosed whereas the ridges are adapted to form concentric circular compartments with the clearances in the joints thereof successively increasing towards the periphery of the dies. The volumes of said compartments also increase from the center towards the periphery of the dies. These compartments are locking in their function and ensure a smooth reduction of pressure exerted by the ductile material on the face surfaces toward the periphery of the dies.
Abstract translation: 沿其周边互连的两个模具在其相对相邻的表面上设置有中心凹部和脊部,后者相对于所述凹部同轴设置。 当模具被拉在一起时,所述凹槽适于形成高压腔室,在该高压腔室中封闭由热和电绝缘材料构成的容器,该容器由全向压缩下延展而形成,而脊部适于形成同心的圆形隔室, 其关节朝向模具的周边依次增加。 所述隔室的体积也从模具的中心向周边增加。 这些隔室具有锁定功能,并且确保平滑地减小由延展性材料在表面上朝向模具的周边施加的压力。

Abstract: A machine is disclosed for converting graphite to diamond which includes a cylindrical reaction chamber and a reaction vessel positioned in the reaction chamber for holding the charge of graphite to be converted to diamond. A piston having a fixed length and fixed diameter is positioned in the reaction chamber with its first end contacting the reaction vessel and its second end extending out of the reaction chamber. Means are provided for applying a force to the second end of the piston, thereby generating high pressure within the reaction chamber. Further means are provided for maintaining the ratio of the unsupported length to the diameter of the piston at a value less than the ratio of the fixed length to the fixed diameter of the piston.

Abstract: An improved bell assembly is provided for use in a hotisostatic-pressing apparatus wherein a gas provides the material pressing and heating medium. The thermal insulating and sealing properties of the bell assembly substantially enhance the efficiency of the natural-convection, closed-loop gas heating system by significantly decreasing heat losses and gas escape.
