Abstract: ABSTRACT OF THE DISCLOSURE           A hard sintered carbide composition and the method of making such composition for use as a cutting material or for use as wear parts or dies and the like, is disclosed. The composition consists essentially of a titanium carbide phase bound together by a binding alloy principally composed of molybdenum and nickel; the titanium carbide contains controlled amounts of dissolved vanadium carbide and/or titanium nitride.  The binding alloy is characterized by the addition of aluminum in controlled amounts and chromium may be added to the binding alloy as a partial substitute for some of the aluminum.  The presence of the dissolved vanadium carbide and/or titanium nitride produces a grain refinement in the carbide phase and the presence of the aluminum tends to form a nickel aluminide in the binding alloy which is of a finely divided character.  The presence of two or more of the elements:  vanadium carbide, titanium nitride and aluminum produce an unprecedented improvement in the defor-mation resistance of a TiC-Ni-Mo composition.           The method requires that the binding alloy powder and the carbide powders be selected as to size (about 3-4 microns) be milled with the additive powders and the compac-ted charge then be sintered at about 1400°C in closed graphite trays in a furnace evacuated to less than 1 micron of mercury pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved process for the manufacture of steels containing nickel, and more parti-cularly to the provision of such an improved process for the manufacture of corrosion-resistant steels.  The specification discloses, in the process for the manufacture of steels con-taining nickel through the refining of a metal bath in a converter, the improvement which comprises adding ferro-nickel shot into the converter while controlling the flow rate of the shot in such a way that the temperature of the converter is maintained at a pre-selected level.  The initial carbon and silicon levels of the metal bath may be higher than 1% and 0.4% respectively.  The added ferro-nickel shot may comprise highly refined shot, the carbon content of which is, at most, equal to the carbon content of the metal bath after the refining process has been completed.  The ferro-nickel shot may comprise slightly refined shot, the silicon content of which is, at least, equal to 0.4% by weight.

Abstract: A B S T R A C T                 METAL DOOR AND HINGE CONSTRUCTION                 A hinge construction particularly designed For exterior usage is provided by the present invention. Two planar sections are comprised of complementary land portions and cutaway portions disposed in spaced apart relationship along the length of the hinge.  The cutaway portions of one section receive the land portions of the other section.  With such configuration only a single thickness of metal separates the hinged member from the mounting member.  First and second barrel mounting sections extend in the same direction outwardly away from the respec-tive first and second planar sections. The two barrel mount-ing sections in turn mount complementary hinge barrels which, when positioned in alignment, receive a hinge pin.  As a result of the hinge mounting sections projecting outwardly away from the hinged member and the mounting members, a weather shield is formed to help keep moisture and dirt out of the opening that is closed by the door.  Location of the hinge barrels spaced from the hinged member and the mounting member also reduces the accumulation of dirt in the hinge.

Abstract: ABSTRACT OF THE DISCLOSURE        An elastic linkage buffer coupling for rail vehicles in which a casing receives a coupling rod and in which the rod is spaced from the casing by means of prestressed elastomeric rings received between peripheral dogs on the rod and corresponding inwardly directed dogs on the casing.

The casing may be mounted on vertically directed pivots on the vehicle, the casing may be made as a pair of mirror-image halves which can be bolted together for adjusting the prestress in the rings and the rings may be slotted so that they can be inserted as half rings before prestressing by tightening of the casing.
