Abstract: In one example, a method includes running a downhole system into a downhole environment that comprises a wellbore, and the downhole system is configured such that a reusable plug of the downhole system is positioned uphole of a perforation gun of the downhole system, then, with the perforation gun, perforating a casing at a stage of the wellbore, and the perforating is performed using a projectile, and the perforating is performed by firing the projectile from a chamber of the perforation gun.

Abstract: A dispenser includes a body that defines a chamber and a barrel that communicate with each other, and a penetrator assembly configured to be received in the chamber. The penetrator assembly includes a penetrator, a propellant operably positioned with respect to the penetrator, a primer in operable communication with the propellant, and an electrical conductor configured and arranged to carry electrical power to the primer. The dispenser may be positioned in a downhole location such as a wellbore, and the penetrator assembly may be fired so that the penetrator perforates a casing in the wellbore.

Abstract: A Method of casting includes providing a mold having one or more article mold cavities. The mold is moved into a furnace. While the mold is in the furnace, the mold is filled with molten metal. After the mold has been removed from the furnace, a heater is positioned adjacent to the mold and heat is transmitted from the heater to the mold. The heater may include electrically energizable resistance type heating elements, or a source of radiant energy or a gas burner.

Abstract: An improved dough sheeting system and method which allow for improved selection of sheeter gap size and which provide a quick release mechanism to prevent damage to sheeter rollers. Hydraulic actuators, attached to a movable roller, hold the roller in a fixed position relative to an opposing roller. The actuators are engaged with a closing force in excess of the force exerted by the sheeted material against the rollers thereby ensuring that the rollers maintain a gap of fixed width. Thermal expansion blocks mounted to the frame or housing of the opposing roller provide a means for fine adjustments in the sheeter gap.

Abstract: Apparatus and method for cooking snack food pieces features a drum-type fryer which transports individual, die-cut piece preforms through hot oil contained within a cooking tank defined between the periphery of the drum and a housing in which the drum is contained. Vacuum transfer and feed rollers transfer the individual piece preforms from a die-cutting roller assembly onto the drum for cooking, and a similar roller transfers the cooked snack food pieces from the drum to a take-away conveyor for subsequent, downstream processing. The pieces are retained by suction against molding surfaces of frying mold elements distributed over the periphery of the frying drum.
