Abstract: ABSTRACT OF THE DISCLOSURE      A method for forming a stamper for use in molding video disc replicas in which a disc-shaped master recording is formed which includes a glass substrate and a thin photore-sist recording layer.  An information signal is recorded in the recording layer in a sequence of spaced pits arranged in a plurality of substantially circular and concentric recording tracks.  A first thin, uniform, metallic film is deposited on the master recording.  A second thin, uniform, metallic film is electroplated on the first film so that the first and second films together form an integral, metallic layer.  The metallic layer is separated from the underlying master and the residual photoresist is removed from the undersurface of the separated metallic layer to form a stamper suitable for use in molding video disc replicas.

Abstract: ABSTRACT OF THE DISCLOSURE      In an electrical anti-short bushing comprising a tubular portion and an outwardly extending flange portion presented by one end of the tubular portion, the bushing which is of split form having a discontinuity extending throughout its axial length is provided with two outwardly projecting, circumferentially spaced ribs which extend axially from the flange portion along at least a portion of the tubular portion of the bushing, with the part of the tubular portion between the ribs being diametrically opposite the axially extending discontinuity.  Thus, when the bushing is operatively mounted on an electrical cable of the type known as BX cable with the tubular portion of the bushing between the outer casing of the cable and the insulated conductor wires disposed therethrough the sharp, jagged edge formed when the helically wound metal cladding strip constituting the outer casing of the cable is cut may be disposed between the ribs, thereby substantially to prevent this sharp, jagged cut coming into alignment with the axial discontinuity in the bushing.  An inspection notch may be provided in the outer edge of the flange portion of the bushing between the ribs, and a resiliently deformable prong which is presented by the inner face of the tubular portion of the bushing and projects, in a direction inclined towards the longitudinal axis thereof, towards and beyond the flange portion of the bushing operatively serves to prevent inadvertent withdrawal of the bushing once it is installed.

Abstract: A B S T R A C T          REFRACTORY, HEAT-INSULATING SLABS           A refractory, heat-insulating slab for use in an inner, expendable lining of a tundish has a facing comprising magnesium oxide, inorganic binder but substantially no organic matter and a different backing.  The facing has a combined water content not exceeding 2% by weight and the backing has a permeability of at least 10 AFS units.           The facing and backing are joined together during formation of the facing or the backing.  In the continuous casting of steel, the slabs have the advantage that there is little or no tendency for a significant amount of hydrogen to be picked up by the steel.

Abstract: ABSTRACT OF THE DISCLOSURE   This application relates to parallel blank mold opening mechanism wherein the split blank molds, of which there are a plurality, are carried in holders that are mounted on horizontal hinge pins adjacent the rear thereof.  These hinge pins are carried at the upper end of crank arms and move toward and away from each other during the cycle of operation of a pneumatic motor.  Each of the mold hangers is provided with a parallel link which is connected between the base of the mold mechanism housing and  he hanger, such that upon opening and closing of the mold the faces of the molds are maintained in a vertical plane.  In addition, the position of the axes of the crank shafts and the hinge pin  are such that the hinge pins move over top dead center or through the vertical plane defined by the axis of the crank shaft upon opening or closing.  In this manner the molds are actually lifted a slight amount during movement from their closed to their open postion.  The molds, of which there are three in number disclosed, are held in closed position with equal closing forces due to the fact that the mold hangers on one side are pivoted from a central pivot and the mold hangers on the other side are split so that the two halves of the mold hangers are each individually pivoted about vertical pivot pins.

Abstract: ROCK BIT CUTTER CONES HAVING             METALLURGICALLY BONDED CUTTER INSERTS                  ABSTRACT OF THE DISCLOSURE          A rock bit cutter cone for a drill bit is disclosed wherein hard carbide cutter inserts are metallurgically bonded into an interior core of the cone through a cladding.  The cladding is bonded onto the exterior surface of the core by a powder metallurgy process.  The cladding retains the inserts in the core.  A thin layer or coating of a suitable metal, preferably nickel, is provided on the carbide insert prior to mounting into the core.  The coating prevents degradation of the carbide through loss of carbon into the core during the powder metallurgy process and accomodates mismatch of thermal expansion between the cutter insert and the core.  The interior of the cone is formed to provide bearing surfaces either by conventional techniques, or by powder metallurgy processes.          Bearing surfaces formed in the interior of the core by powder metallurgy processes may be hard so as to permit an open bearing structure for the drill bit.

Abstract: ABSTRACT OF THE DISCLOSURE:            A whole frame/half frame camera has a push bar extending outside the camera body to allow the activation of a regulating plate inside the camera body.  When actuated, the plate moves in a fixed orbit to be positioned in one of two positions.  In one position, the plate causes a view shield device to shield a portion of the view area on two sides of a viewfinder, and induces a pair of opaque movable blades to shield an exposure window also from two sides.  In this position the plate also activates a clutch device for con-trolling a film advance wheel such that the wheel will rotate only a half cycle for each photograph taken,  so reducing the length of film wound to one half of the length that is wound for a whole frame photograph.
