Abstract: An apparatus for discharging sample fluid from a bailer with a ball-joint and a method of using thereof. The apparatus has a body, an interior and an exterior, a top opening and a bottom opening, and a lip disposed around the top opening. The bottom of the apparatus has a bailer-support disposed across the diameter of the bottom opening. A pin is located at the center of the bailer-support. The apparatus functions as a bailer discharge device. The apparatus is designed to be placed into an opening of a bucket or drum and is adapted to discharge sample fluid from the base of a bailer into a bucket or drum when the bailer with a ball-joint is inserted through the top opening of the apparatus and rests on the pin attached to the bailer-support support. The pin acts to release the ball-joint thereby allowing the sample fluid to be discharged into the bucket or drum.

Abstract: A shield for a computer monitor comprises a hollow cylindrical magnetic sleeve disposed around at least a portion of the yoke windings of the monitor. The sleeve has a diameter greater than the diameter of the yoke windings. A cathode ray tube (CRT) standoff for the shield provides for ease of shield installation and continued operation of the monitor within specification without impairing image integrity (i.e. distortion, color impurity or brightness). The standoff creates a specific distance (critical threshold) between the glass bell of the CRT and the shield that prevents image distortion that cannot be overcome through adjusments of the monitor controls (critical interference).
