The funnel side walls which extend generally parallel to the horizontal axis of the faceplate have a central portion thereof which is substantially flat in all cross sections thereof and is smoothly interconnected with the remaining portions of said side walls. The funnel side walls which extend generally parallel to the vertical axis of the faceplate have portions thereof which are substantially bowed outwardly relative to the vertical axis and side walls which extend generally parallel to the horizontal axis of the faceplate. |
