Abstract: A beaver controlling culvert attachment prevents beavers from disturbing the flow of water through a culvert. An upstream unit includes a vertical pipe having an upper grate, which prevents the entrance of beavers and debris, while allowing the entrance of water during periods of high water levels. A horizontal pipe has an upstream end attached to an upper portion of the vertical pipe and a downstream end attached to an upstream end of the culvert by an attachment plate. A basket insert is carried within the vertical pipe, and is movable between an in-use position, wherein a grate prevents entrance to the bottom of the vertical pipe, and a clean-out position wherein the grill is elevated to allow disposal of accumulated debris through the horizontal pipe and culvert. A downstream grate prevents beavers from entering the downstream end of the culvert, and from filling the culvert with debris.

Abstract: A shooting range that has a target chamber position at the target end. A camera on the chamber transmits an image of the target to the shooting end where it is displayed on a screen of a video micrometer. The video micrometer has cross hair reticles that measure a shot pattern generated on the target. The video micrometer has a tape recorder for recording the transmitted image, a printer for printing a hard copy of the pattern, a keyboard for data input, and is connectable to a computer for input of the shot pattern data.
