Abstract: A holder for securely and adjustably supporting an article such as an anti-glare screen on another article such as a display monitor comprises an L-shaped hanger with teeth formed along the first one of its legs. An elongated sleeve having a tooth formed preferably at or near the end thereof is slidably mounted on the first leg. The tooth engages the hanger teeth in a ratchet-type arrangement which permits adjustment of the position of the sleeve on the hanger and thus of the cover on the monitor, while permitting a secure sliding fit between the hanger and the sleeve. Preferably, an adhesive strip secures the sleeve of the hanger to the cover and the second leg is positioned along a top surface of the monitor. Preferably, the underside of the second hanger leg is or is coated with a high friction material which positions the hanger on the monitor, secured against slipping or moving laterally, yet permits ready removal by lifting the hanger upward.

Abstract: An air inlet control assembly for cooling towers including air control panel members pivotally secured to the louver blades. The panel members are pivotted between a down position wherein they preclude the entry of air between the louver blades and an up position wherein they permit the entry of air between the louver blades. The panel members are formed from a lightweight fiberglass material and include means to direct liquid away from the outer edge of the louver blade when the panel member is in its down position. Cover members extend across the louver blade support arms and are releasably secured to the adjacent panel members when the panel members are in their down positions.
