Abstract: An apparatus coupled to an air-circulating device for reducing temperature of a surrounding is disclosed. The apparatus comprises a tray and upstanding sidewalls coupled to the tray. The upstanding sidewalls are covered with moss or any other suitable absorbent material. The apparatus comprises a pump provided at the bottom of the tray. Further, the apparatus comprises a hose in which one end of the hose is coupled to the pump. The apparatus comprises a canvas or any other suitable flexible material provided on the upstanding sidewalls and a lid provided at the top of the upstanding sidewalls and coupled to the canvas or any other suitable flexible material. The apparatus is placed behind the air-circulating device, wherein water stored in the tray is pumped using the pump through the hose and the water is made to fall onto the upstanding sidewalls. The air-circulating device draws air and moisture/water from the apparatus and directs the air current in a desired direction.

Abstract: A movie projection system includes a film projector for projecting moving images of a film while broadcasting the film sound track in two or more languages simultaneously to different film viewers who view the film at the same theater. A time code reader detects time code signals recorded on the film and derives sync signals therefrom. A playback system receives the sync signals for generating first and second sound tracks, in first and second languages, respectively, each synchronized with the images recorded on the film. The first sound track is broadcast over the usual theater sound system, while the second sound track is transmitted to receivers worn by those viewers who speak the second language.
