Improved Engineering Designs for Stage Doors, Transparency Screens, and Water Tank Bulkheads

This paper describes three innovations in studio stage construction: (1) Vertical-Lift Stage Separation Doors. These doors eliminate the hinged type formerly used, which required so much valuable stage space. Ease of operation and good sound insulation have been obtained between adjacent stages. (2) A Movable 50-Foot Transparency Screen. A screen has been suspended from a monorail system for storage outside the stage. It can be readily rolled into position in the space normally occupied by the vertical lift doors to permit large screen transparency shots to be made between two connecting stages. (3) A Vertical-Lift Disappearing Bulkhead for a Stage Water Tank. A hydraulically lifted bulkhead has been designed which permits a large sound stage to be quickly converted into a 7-ft deep tank.
