device can be employed so that it will not depend on the operator to decide when and where the curtain control switch must be applied. A step in this direction is reflected in the recent development of an accessory called a ttlatchin relayfl In the example cited above the addition of this unit would provide for an extra pre-set stophat the curtain location for a 4 to 3 showing. The machine Would automatically stop at that set position and when it was desired to move the curtain to expose the entire wide screen, the ttStartll button (using the three button model) would be pressed. However, as inferred, only one additional stop would be aii'orded with this special relay.

Another possibility exists for those who insist on more than two automatic stops. This involves the placing of limit switches on the track itself. While such a system is entirely feasible and anrds an opportunity to have an unlimited number of pre-set stops, it has its drawbacks principally because of the prohibitive cost of installation and adjustments. Also there is always the problem of what to do with the wires extending from the limit switches on the track not to mention the necessity for the stagchand to climb a ladder and set the limit switches on the track itself each time a new movie involving a different screen ratio is presented.

One other track arrangement bears mentioning. Where a wall-to-wall proscenium track is used for wide screen showings and where it is impractical for the booth ope 'ator to have to control desired curtain positions by eye, it is possible to incorponte an arrangement
