    Abstract: A blind fastener including a core bolt having a shank with a head and a threaded portion, and a sleeve having an elongated body with a head, an internal threaded portion, and a tapered notch formed within an exterior surface thereof and defined by a tapered portion having a slope and a frictional enhanced surface. The core bolt is installed within the sleeve such that its threaded portion engages threadedly the internal threaded portion of the sleeve. During installation of the fastener within the plurality of workpieces, a bulb is formed on the elongated body of the sleeve, the bulb defining a portion of a bulbed portion. When a selected axial force is reached, the bulbed portion separates from the elongated body and engages axially the tapered portion of the sleeve, increasing the diameter of the bulb which engages a blind side of one of the workpieces.

    Abstract: An injection molding apparatus includes a control system for controlling the injection of fluid molding material during an injection cycle. The control system includes a controller for generating control signals and a servo control circuit responsive to the control signals for controlling the injection of the fluid molding material. The servo control circuit implements a first control mode which controls only a velocity of the fluid molding material during a first part of the injection cycle and a second control mode which controls only a pressure of the fluid molding material during a second part of the injection cycle.
