Abstract: PCD and PCBN composite constructions have an ordered structure of two or more material phases that are combined together in a packed or interwoven configuration. One of the material phases is formed from materials selected from the group consisting of: polycrystalline diamond, polycrystalline cubic boron nitride; carbides, borides, nitrides, and carbonitrides from groups IVA, VA, and VIA of the Periodic Table; and mixtures thereof. Another material phase is preferably formed from a material having a degree of ductility that is higher than that of the first material phase. Example second material phase materials include those selected from the group consisting of cermets, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and mixtures thereof. Example composite constructions include those having: (1) a first material phase formed from WC-Co, and a second material phase formed from Co; (2) a first material phase is selected from the group consisting of polycrystalline diamond, polycrystalline cubic boron nitride, and mixtures thereof, and a second material phase being a cermet material; and (3) a first material phase formed from polycrystalline diamond and a second material phase formed from WC-Co. Alternatively, the material phases can be formed from the same materials, only in different proportions. Woven or packed composite constructions have surface structures formed from a number of the order material phases (made from the same, similar, or different materials) that are specifically engineered (in terms of geometry, arrangement, and materials) to provide optimized, rather than compromised, performance properties.

Abstract: Procédé et dispositif destinés au traitement, dans un système de base de données, d'éléments de données associés à des types de données dont ledit système ignore la structure d'origine. Les éléments de données sont stockés dans le système de base de données dans leur structure d'origine, même si ledit système ne la comprend pas. Pour stocker les éléments de données, le système de base données fait appel à une routine de décapage fournie par l'utilisateur, ou par le sous-système d'exécution de l'environnement de programmation propre à l'élément de donnée. Pour extraire la routine de la mémoire, le système de base de données fait appel à une routine non décapante, également fournie par l'utilisateur ou par le sous-système d'exécution approprié. La base de données conservant les éléments de données dans leur format d'origine, aucune conversion n'est requise car les éléments de données sont transmises entre le système de base de données et les routines extérieures qui manipulent les éléments de données. L'invention concerne également des techniques qui permettent de déclarer des attributs de l'élément de donnée accessible dans le système de base de données. L'utilisateur fournit les routines que ledit système peut appeler afin d'accéder aux attributs déclarés, lesquels peuvent être différents des attributs réels de l'élément de donnée dans son environnement d'origine.

Abstract: A method for the manufacture of heavy metal powder-based frangible projectil es which are relatively easy and inexpensive to manufacture and which exhibit a selectable variety of desirable physical and/or performance properties. The projectiles of the present invention are powder-based, preferably including predominantly tungsten powd er as a heavy metal, particularly a tungsten powder which includes a predominate portion of finely sized particles. Lighter metal powders, also preferably having a predominate portion of finely sized particles, may be employed in combination with the tungsten to achieve certa in desired results. Importantly, the present inventor has found that inclusion of a non-metal matrix powder, also of finely sized particles, in a mixture of a heavy metal powder, such as tungsten powder, and a light metal powder, may be employed in a variety of combinations to produce a projectile which is fully frangible upon striking a target (no ricochet), or which is frangible after either partial or full penetration of a selected target, either a semi-solid (e.g., a gel block) or a solid (e.g., a 1/4 inch thick cold rolled steel plate at an angle of about 90 degrees).
