Abstract: A hybrid yarn filament and sleeve constructed therefrom for protecting elongate members against at least one of EMI, RFI or ESD is provided, along with methods of constructing the hybrid yarn filament and sleeves. The hybrid yarn filament has a nonconductive filament and at least one conductive wire filament overlying an outer surface of the nonconductive filament. The hybrid yarn filament is arranged in electrical communication with itself or other hybrid yarn filaments during construction of the sleeve to provide uniform shielding against EMI, RFI, and and/or ESD.

Abstract: A mold assembly for forming a piston and method of molding a piston therewith includes a pair of mold halves moveable toward and away from one another along a linear path that is substantially perpendicular to a longitudinal central axis of the piston between an engaged position to provide at least a portion of a mold cavity for forming an outer periphery of the piston and a disengaged position to allow extraction of the piston from the mold cavity. The assembly also has a pair of cooling gallery mandrels moveable along a linear path into an engaged position between the pair of mold halves to form an undercut cooling gallery of the piston. The pair of cooling gallery mandrels are movable to a disengaged position to allow extraction of the piston vertically along the axis.

Abstract: A knit protective sleeve and method of construction thereof provides a continuous and seamless sleeve wall knit from one or more yarns extending between opposite open ends of the sleeve. At least one heat vent opening is integrally knit within the wall between the ends.

Abstract: A knit tubular protective sleeve and method of construction thereof provides a continuous and seamless tubular wall knit from one or more yarns extending between opposite open ends of the sleeve. At least one opening is integrally knit within the tubular wall between the ends. The opening has a circumferentially continuous, knit outer periphery.
