    摘要： A procedure for examining and inspecting drilled holes or other metal surface conformations by applying a castable, two component, magnetically active material comprised of room temperature vulcanizing rubber or a polymerizing material containing magnetizable particles and specific sensitizing agents, magnetizing the area to be inspected, and curing the castable material to form a permanent replica impression of the inspection area which, when removed, reveals the presence of surface flaws, such as cracks, scratches, tool marks or dimensional inaccuracies and subsurface flaws which may tend to develop in structurally deficient members.

    摘要： A superindurate, texturally stable abrasive composite material useful in the making of cutting and abrading tools, such as oil well drills, industrial metal cutting bits, mills, planar knives and abrasive grinders. The superficies of the object tool is comprised of the outer face of a tough matrix material and the projecting ends of a preferentially oriented indurate fibers or filaments, such as boron or the indurate intermetallic compounds of boron endowed with a hardness closely approaching that of industrial diamonds, which have been dispersed in collocated array and embodied within a tough matrix material such, for example, as in a sponge iron matrix which has been briquetted in the configuration of the object tool and then heated at temperatures sufficient for incipient fusion to occur to form the composite tool. Other ductile metals such as aluminum, nickel and cobalt, including certain of their alloys, together with steel and titanium are further examples of matrix materials which may be employed. The indurate filaments are so dispersed and collocated that the outer ends of the fibers or filaments are aligned normal to the tool''s work-taction surface and consequently to the surface of the object material to be cut or abraded.

    摘要： A combination of materials and method of using them in the forming of extremely long wear life and breakage resistant abrasive tools such as cutoff and grinding wheels. This invention utilizes superindurate materials such as boron, boron nitrides or boron carbides as the incorporated abrasive material. The several methods for incorporation of these abrasive materials include lamination of filamentous tape containing the chosen abrasive and spinning or casting a tool of the desired shape from a resinous matrix containing fibers of the chosen abrasive.
