Abstract

1309000 Ventilators PERFONIT Ltd 15 Oct 1971 [16 Oct 1970] 49326/70 Heading F4V [Also in Division E1] A suspended ceiling panel has at least one slot therethrough which may be obstructed to different extents by a flat strip secured to the back of the panel by a pivot perpendicular thereto. The strip may be moved between positions defined by a stop, in the form of a staple spanning the slot and strip, by a pointed tool engaging an indentation or hole in the strip from the face side of the panel. Alternatively the pivot either centrally positioned or at one end of the slot may penetrate the panel and be adjusted with a screwdriver. The panel may be formed of mineral fibre insulation board.
