Abstract: An online data validator is a digital imaging system integrated onto the front side of a printing unit wherein an exit of the printing unit is set on the same side close to the online data validator for a media exiting therefrom. The online data validator comprises a controller facilitating communication with a printing unit controller and controlling overall operation of the online data validator functions; a camera module including a sensor PCB and an optical lens, wherein the sensor PCB contains a camera sensor for capturing 2D digital images of moving labels; and a light source module including a lightbar, a lightbar PCB, a Fresnel lens and a window for providing uniform and flattened illumination on the media.

Abstract: Embodiments of a flow limiting duct vent valve (DVV) are provided, as are embodiments of a bleed air system including a flow limiting DVV. In one embodiment, the bleed air system a flow limiting DVV and a first valved device, such as a high pressure regulator. The DVV includes, in turn, a housing assembly having an inlet and an outlet. The inlet is fluidly coupled to the valved device when the bleed air system is installed on a gas turbine engine. A valve element is mounted in the housing assembly and, during operation of the DVV, moves from: (i) the closed position to an open vent position when the pressure differential across the valve element exceeds a first threshold, and (ii) from the open vent position to an overpressure shutoff position when the pressure differential across the valve element exceeds a second threshold greater than the first threshold.

Abstract: In one embodiment, a method for preventing hammer coils of a line printer hammer bank from overheating during printing includes establishing the maximum allowable temperature threshold of any given hammer coil, monitoring the temperature of all hammer coils during printing, keeping a moving average of dots printed per unit time on each hammer coil, and if one or more coils reach a temperature higher than the threshold, determining the current maximum dot-per-hammer density that the hot coils can print per stroke of the hammer bank that will enable them to cool down adequately from their current temperatures. The rate of printing is restricted to this current established maximum dot-per-hammer density on only those coils which have a temperature at or above the maximum allowable temperature, minus a suitable hysteresis.

Abstract: An apparatus is provided for a valve assembly comprising a valve body, a valve element, an actuator housing, an actuator, an unlocked storage opening, a locked storage opening, and a lock. The valve body has an inlet port, an outlet port, and a flow passage therebetween. The valve element is movably disposed within the valve body flow passage. The actuator is disposed within the actuator housing, coupled to the valve element, and operable to move the valve. The unlocked and locked storage openings are formed in the actuator housing. The lock is selectively insertable into, and movable between, the unlocked and locked storage openings. When in the unlocked storage opening, the lock does not engage the actuator, and valve movement is thereby allowed. When in the locked storage opening, the lock engages at least a portion of the actuator, thereby at least inhibiting valve movement.

Abstract: A valve assembly is provided including an injection molded flow body having at least one inlet port, at least one outlet port, and a flow passage there between. The injection molded flow body is formed of a high performance engineering thermoplastic resin. A plurality of reinforcement fibers may be homogeneously suspended in the high performance engineering thermoplastic resin and provide increased strength and temperature capability for use in high temperature applications.

Abstract: A valve assembly is provided including a thermoplastic injection molded flow body and an electrical bonding connection providing a bonding path between the thermoplastic injection molded flow body and an external ground point. The thermoplastic injection molded flow body is formed of a resin having a fill matrix suspended therein. The electrical bonding connection includes either a metallic saddle and a retaining bolt, mechanically retaining the metallic saddle to a support rib of the valve flow body or a metallic threaded insert molded into the at least one support rib and a retaining bolt inserted into mating threads of the metallic threaded insert. The electrical bonding connection provides a bonding path between the valve flow body and an external ground point.
