found out later that something had
          been placed inside the wall between
          the box and the auditorium to reduce
          noise.
            The arc-lamps were AC (alternating
          current) hand fed and used 7mm
          carbons. These hummed, as might be
          expected. The Bramley shutters also
          chattered and hummed. The picture
          change-over between projectors was
          done by gripping a metal bar attached
          to two small galvanised iron sheets and
          sliding the sheets sideways in tracks
          attached to the wall. The steel sheets
          had zig-zag edges for a snug fit. We
          could if we wished, do a slow wipe
          across the screen.
            My guess was that at an earlier
          time the change-over was done by the
          dowsers. There was a pair of small
          pulleys attached to the ceiling where it
          seemed a cord, wire or chain would
          have passed from the dowser of one
          projector to that of the other.
            The sound changeover was through
          the exciter lamps. Each projector had
          its own exciter lamp supply and
          switch. Thus, a change over from one
          projector to the other was really a two
          man job – or one man moving very
          quickly. There were two amplifiers,
          each complete and separate except for
