Abstract: An apparatus, comprising: a substrate configured into a casing, a propellant configured between a projectile positioned/configured within the casing and an end of the casing, the propellant configured to expand upon a firing event and project the projectile from the casing; and a coating comprising a conformal coating layer having a particulate boron nitride dispersed therein, wherein the coating is configured to cover at least one of the inner sidewall and the outer sidewall, such that at least one side of the substrate is covered by the coating.

Abstract: An apparatus, method and composition for long length tubing includes continuous production of long length seamless aluminum tubing suitable for use as coiled tubing in hydrocarbon wells. A 2XXX aluminum alloy may be used in combination with a continuous casting/extrusion apparatus using aluminum from a melt. Other metals may be used, as well as continuously cast rod from a casting wheel and belt or conform extruder, which is processed to form a hollow and then sized by drawing.

Abstract: The instant disclosure is directed towards shot shell configurations and methods of making the same.

Abstract: A casting apparatus (10) for direct chill casting metal includes a tundish (12) containing a supply of molten metal, a casting mold (14), and a starter block (44) associated with the casting mold (14). The casting mold (14) is in fluid communication with the tundish (12) through a passage (22) defined in the tundish wall. The casting mold (14) includes a header plate (24), a casting ring (26), and a feed ring (28). The header plate (24) defines an arcuate shaped opening (36) connected to the passage (22). The header plate (24) has an upstream side (38) and a downstream side (40). The casting ring (26) is connected to the downstream side (40) of the header plate (24) and defines a groove (52) proximate to the sidewall (48) of the header plate (24). The feed ring (28) is disposed in the groove.
