Abstract: A container for a semiconductor device has a metal plate and a body of synthetic resin which encapsulates a part of the plate, keeping a large surface thereof exposed. In the area separating the part encapsulated within the body of resin and the part without the resin, the plate has two opposed side notches and at least one groove connecting them.

Abstract: This invention relates to an extractor/straightener device for continuous metal casting installations, particularly for curved continuous casting. In order to cast either round-section strands and square-, rectangular- or polygonal-section strands, the extractor/straightener device (10) comprises two successive pairs of extractor rollers, one pair including rollers (11, 12) with a groove or race therein (15) for round-section strands (7'), the other pair including cylindrical rollers (13, 14) for square-section strands (7"). The two pairs of extractor rollers (11, 12 and 13, 14) are followed by a straightener roller (31). Means are provided to regulate the distance between the rollers (11, 12 and 13, 14) of each pair of extractor rollers so as to exert a tractive action on the strand (7' or 7"), alternately, by means of either the former or the latter pair of said rollers (11, 12 or 13, 14) depending upon the profile of said strand.

Abstract: A continuous casting plant comprising at least one casting line presenting a curved guide path for bending the casting leaving the casting mold from a substantially vertical direction to a rectilinear, substantially horizontal direction through a straightening machine and across a following cutting device for shearing the casting in a number of consecutive sections of predetermined length. Between the straightening machine and the cutting device a stepwise feeding device is provided for feeding the tail-end section of the casting across the cutting device and for operating the cutting device after each step so as to shear the tail-end section of the casting into comparatively small stubs which are discarded beneath the path of the casting by a chute.

Abstract: Apparatus for the continuous casting of metals, particularly of steel in curved path, in which in the initial portion of the curved path of the casting bar below the mold the bar-guiding means are missing. According to the invention, in the apparatus of this type the casting bar-guiding means provided only in the final portion of the curved path of the casting bar, upstream of the withdrawing and straightening mechanism, comprise at least one pair of powered pulling rollers arranged near their upper, or mold-facing end. To this apparatus there is associated a curved, rigid starter bar which is bent substantially to the same curvature as the curved path of the bar, and is of such a length that when it is positioned to close the mold outlet, it is still engaged between the first pair of powered pulling roller of the casting bar-guiding means provided in the last portion of the curved path of the casting bar, upstream of the withdrawing and straightening mechanism.

Abstract: The drawing and straightening machine for use in continuous casting plants, comprises a first pair of superposed pinch rolls, arranged at the bottom end of the curved guide path section, passing through which the casting is bent, and a second pair of pinch rollers arranged subsequently to the first pair. The second pair of pinch rollers is mounted on the machine frame so as to be capable of swinging from an upper starting position, at which the rolls are operatively arranged on the curvilinear upwardly directed prosecution of the curved path of the casting, to a lower straightening position, at which the rolls are in alignment with the rectilinear guide section onto which the straightened casting moves for further processing. Each roll of the second pair of rolls is mounted on a roll-carrier, and each roll-carrier is hinged to the machine frame around a single common fulcrum axis.

Abstract: In a continuous casting plant comprising a fixed frame, a table, and a mold supported by said table, a mold rocking device comprising at least one first bell-crank lever keyed at its apex to a first shaft rotatably journalled by said fixed frame, said first lever being pivotably connected at one end to one side of said table; at least one second bell-crank lever keyed at its apex to a second shaft, parallel to said first shaft, rotatably journalled by said fixed frame, said second lever being connected, in a slidable and pivotable manner, at one end to the side of said table opposite to the one to which the said first lever is pivotably connected; the second end of said second bell-crank lever being connected to a rocking device; and means for transmitting the said rocking movement from said second bell-crank lever to the second end of said first bell-crank lever.

Abstract: A mold for the continuous casting of molten steel comprising an inner tubular mantle surrounded by an outer tubular mantle, leaving between them a cooling jacket for the flow of cooling water. The mold is surrounded, starting from its lower end, and up to substantially one half of its height, by an outer, funnel shaped mantle, defining in cooperation with the outer mantle of the mold, a cooling water inlet manifold, the cross sectional area of the flow passage of which is decreasing from its upper end to its lower end. The said cooling water inlet manifold communicates at its lower end through suitable ports with the lower end of the cooling jacket of the mold, while at its upper end it communicates with the cooling water supply pipes. The upper end of the mold is surrounded by an outer, funnel shaped, mantle defining in cooperation with the outer mantle of the mold an outlet manifold, the cross sectional area of the flow passage of which is increasing from its upper end to its lower end.

Abstract: In a continuous casting plant for metals comprising a fixed frame, a first table fastened to said fixed frame, vertical guide means secured to said first table for supporting and guiding a second table for reciprocating movement in a vertical plane, and a mold supported by said second table, a mold rocking device comprising a motor secured to said first table, a crank keyed on the output shaft of said motor, a horizontal lever fulcrumed at an intermediate position to a frame secured to said first table, a first connecting rod articulated at one end to said crank, and at its other end to one end of said lever, and a second connecting rod articulated at one end to the second end of said lever and at its other end to a pin carried by said second table.
