Abstract: A processing system and associated method for milling boron with impurity contamination avoidance. The system includes a jet mill for reducing the particle size of a boron feed stock, and a feed stock inlet for delivering the boron feed stock toward the jet mill. The system includes at least one inlet for delivering at least one gas into the jet mill. The gas and the boron feed stock comingle within the jet mill during milling reduction of boron particle size. The system includes a source of the at least one gas operatively connected to the at least one inlet, with the at least one gas being a gas that avoids transferring impurity during milling reduction of boron particle size.

Abstract: A mounting structure for an arc tube within an outer envelope of an HID lamp, including an elongated frame supported at one end by a stem assembly and a stem clamp having one or more frame retaining tabs crimped around a portion of the frame.

Abstract: A system and method for mechanically supporting and electrically coupling arc tubes in high intensity discharge (“HID”) lamps such as metal halide lamps. The system and method provides mechanical support and electrical coupling of the arc tube in HID lamps with few or no welds and is particularly suited for HID lamps having relatively large arc tubes, e.g. lamps having wattages greater than about 150 watts or other wattage lamps having a heat reflector mounted near the base of the lamp.
