Abstract: ABSTRACT OF THE DISCLOSURE            A composite material consisting of particles of a sintered metal-ceramic, supported in a metal matrix is pro-duced by packing a mold with sintered particles having a larger average particle size than those desired in the final composite and particles of the matrix metal.  A controlled quantity of heat is then applied to the mass to bring the temperature of the matrix metal above its melting temperature and above the degradation temperature of the sintered particles.          The surfaces of the sintered particles in contact with the metal are degradated by de-sintering, diffusion and solution into the molten metal reducing the size of the particles.        The heat source is removed before the particles have been reduced in size to their final desired size so that the mass cools and upon solidification the particles have reached their desired final particle size.  In the final composite the remaining particles are surrounded by zones of an alloy of the matrix metal and the dissolved constituents of the sintered particles.

Abstract: ABSTRACT OF THE DISCLOSURE: This invention relates to improved apparatus for sawing stone blocks.  A number of rotary saw blades are arranged in series in the cutting plane of the blades with the cutting depth of each blade being successively deeper to cut the blocks to a predetermined depth.  Each block is fed past the blades on a work carrier truck and after it is partially cut, reversing apparatus turns it over on the truck.  The truck is then again passed by the rotary blades and the cut is completed from the other side of the block.  This has the advantage of reducing the depth of each cut and thus speeding up the cutting operation.

Abstract: METHOD AND APPARATUS FOR INDIVIDUAL CONTROL     OF INJECTION MOLD SHUT-OFF BUSHINGS                 ABSTRACT OF THE DISCLOSURE      A method and apparatus for multiple cavity injection molding which permits individual variation of gate opening time for mold shut-off bushings.  The gate pins for the shut-off bushings are con-trolled by individual double-acting fluid motors, the bushings being fed by a common manifold.  Gate opening is thus not dependent upon attainment of a predetermined injection pressure.  Closure of the gate for each cavity will permit material to be fed faster to the other cavities.  Novel means is provided for securing each gate pin to its actuating cylinder, which minimizes heat transfer to the motor, accommodates expansion of the material manifold and permits gate opening adjustment.  The fluid motors are end-mounted on an actuating fluid manifold, allowing close juxtaposition.  A cycle counter may be used to control inventory.

Abstract: METHOD FOR REMOVING CONDUCTORS FROM THE SHEATHING OF A CABLE          ABSTRACT OF THE DISCLOSURE          Conductors are removed from the sheathing of a cable by attaching a sleeve to the outer surface at one end of the sheathing of a selected length of cable.  When the sheathing is made of lead, the sleeve has internal threads that are passed onto the sheathing.  Alternative measures for attaching the sleeve to the sheathing include forming a bonded film of solder or cured adhesive.  The free end of the sleeve is joined with a fitted coupler by a conduit to a source of lubricant under pressure.  Lubri-cant is forced through the sleeve into the sheathing under sufficient pressure to cause the lubricant to flow along the conductors of the cable.  After the lubricant dis-perses within the sheathing, the conductors are withdrawn.          When the cable is buried, anchoring of the sheathing is usually unnecessary.  When anchoring is necessary, a T-shaped anchor is attached by threads to the sleeve and a rope is used to attach the anchor to a support surface.
