Abstract: Method of melting a metallic material such as a metal or or alloy involves the steps of disposing the metal or alloy in a crucible or other melting vessel having an induction coil disposed about an upstanding side wall of the vessel. The side wall comprises graphite and has a side wall thickness not exceeding about 0.50 inch. The induction coil is energized to generate an electromagnetic field effective to heat and melt the metal or alloy in the crucible and having a low enough frequency that the side wall is so transparent (does not suscept) to the electromagnetic field of the induction coil that a solid skull forms on the side wall to separate the melted metal or alloy from the side wall of the crucible.

Abstract: Method and apparatus for casting a metallic material involves the steps of providing a non-metallic mold in a mold-receiving chamber disposed in at least one of relatively movable first and second members, communicating a mold cavity in the mold to a gating passage disposed in at least one of the first and second metallic members, communicating the gating passage to a shot sleeve, and flowing metallic material from the shot sleeve to the gating passage and into the non-metallic mold.

Abstract: Heat treatment of alloys having elements for improving grain boundary strength is disclosed. Components directly after castings often reveal low or no transverse grain boundary strength, so that cracks do appear and decrease the yield rate. The provided measures do not lead to low transverse grain boundary strength but maintains efficient grain boundary strength, so that the yield rate of components without cracks is increased.

Abstract: Glass-forming die, such as a parsain-forming or bottle-forming die, includes a die body having a molding surface with a curved contour to form at least a portion of a glass bottle or other article to be made. The die body has one or more cooling passages inside the body wherein the cooling passages is/are non-linear (non-straight) along at least a portion of their length to improve temperature control of the die during the glass forming operation. To this end, the cooling passages are curved in a manner to generally follow the curved contour along at least a portion of the length of the curved contour, and may include heat radiating or turbulating elements in the cooling passage. The glass-forming die alternately, or in addition, can include integral cooling fins, ribs or other heat radiating element on one or more exterior regions of the die.

Abstract: Rhenium-bearing single crystal nickel base superalloy consisting essentially of, in weight %, about 12.5% to about 13.5% Cr, 9.0 to about 9.9% Co, about 4.7 to about 5.1% Ti, about 2.8 to about 3.2% Al, about 2.8 to about 4.3% W, about 1.4 to about 1.6% Mo, about 2.85 to about 3.1% Ta, about 1.0 to about 6.0% Re, about 0.08 to about 0.11% C, about 0.010 to about 0.015% B, up to about 0.15% Nb, up to about 0.15% Hf, up to about 0.003% Zr, and balance Ni and incidental impurities.

Abstract: A seat assembly is disclosed comprising a pivotable backrest, an auxiliary seat, and first and second latches. The first latch is fixedly connected to the bottom cushion and pivotable about a pivot point between a deployed position and a stowed position. The first latch has an opening and a groove extending from the opening, the opening including an arcuate border having a substantially constant radius from the pivot point. The second latch includes a lower bracket arm and an upper bracket arm connected to the backrest, the upper bracket arm including a latch finger and a crank. In a first position, the latch finger engages a catch in the lower bracket arm to lock the backrest in the use position and a distal end of the crank extends into the opening of the first latch. In a second position, the latch finger does not engage the catch and the distal end of the crank extends into the groove of the first latch.

Abstract: A shaker for sprinkling a preset amount of a granulated material, such as table salt, having a removable closure with a plurality of small apertures, an upper discharge chamber below the closure for receiving a granulated material from a measuring chamber in a lower portion of the shaker and an intermediate chamber between the upper discharge chamber and lower measuring chamber for storing granulated material. The intermediate chamber has a plurality of small apertures for filling the measuring chamber with a preset amount of granulated material from the intermediate chamber. A delivery tube extends upwardly from the lower measuring chamber to the discharge chamber for emptying the measuring lower chamber of the preset amount of granulated material when the shaker is inverted. The upper portion of the measuring chamber forms a shake-back guard to prevent additional granulated material from entering the measuring chamber when the shaker is inverted and shaken to sprinkle the material from the shaker.

Abstract: A combination of components for mounting a receiving and transmitting antenna, especially a CB antenna, on a conveyance, especially a motor vehicle, so that the components are easily adjusted and locked in assembled relationship for use and also easily separable for safe concealment during storage.
