Previous Demonstration
After Captain West had read his paper at Zurich he pressed ahead with the objective of showing realistically the salient points of his plan for cinema television in a series of demonstrations to many interested bodies at a cinema in Bromley, Kent.2 Each of these demonstrations included programs built up partly from the B.B.C. transmissions and partly from our own film scanner and studio at Sydenham.
The press comments were highly complimentary, and Captain West was extremely enthusiastic over the opportunity given to Cinema-Television to bring our equipment to Milan and demonstrate it in cooperation with the Marconi Company at this great Exhibition.
During the last year our technicians have had many second thoughts, some of which have been incorporated in this first design of equipment and others have still to be further experimented with in the laboratory. We have also learned much about the performance of this unique type of equipment in theaters, about the presentation of television programs and the problems of meeting the stringent conditions imposed by the public safety authorities.
It is against this background that I am presenting my paper today. I propose to indicate the general arrangement of the projector being
