Abstract: A pixelated X-ray conversion screen includes a metal aperture sheet having a pixel hole filled with a scintillator material, wherein an area of the pixel hole is equal to or less than about 0.25 mm2.

Abstract: Apparatus and a method accomplished by the apparatus is disclosed for cleaning shards, such as clay pigeon fragments, of debris and contaminant materials for recycling. The apparatus includes a reservoir containing a washing fluid and a moving conveyor partially submerged in the fluid. A screen has an outlet positioned above the submerged portion of the conveyor so that the shards may pass along the screen to the conveyor while some debris and contaminant material falls through the screen and into the reservoir away from the conveyor. The shards are washed in the fluid and are conveyed by the conveyor out of the fluid and past a bank of spray nozzles which spray the shards in a direction against the motion of the conveyor. Preferably, the screen from the bottom of a hopper and the shards are introduced by the hopper onto the conveyor under the influence of a fluid spray. A pump system circulates fluid through the various sprayers. A weir is included to trap buoyant debris.

Abstract: An improved phosphor admixture is provided for an electroluminescent cell or lamp which reduces the electric arc susceptibility during normal operation. Said phosphor admixture includes an electrically non-conductive, same color light-transmitting particulate solid as a means of reducing the current density of said electroluminescent cell during operation with a minimum brightness loss.
