SHOWMEN'S TRADE REVIEW, January 4, 1947
New and Helpful Intercom Systems
To control his theatre and the actions of his subordinates the manager must be able to communicate with employes who are not stationed in his immediate presence— with the projectionists, for example.
Inter-com phones, generally used for this purpose, have the disadvantage that the employe called must drop whatever he is doing to pick up the phone.
Theatre business is one business where this is impractical. It may happen that some employes — such as projectionists — can't stop what they are doing without stopping the show.
Loudtalking inter-com systems which enable the person called to hear and answer while remaining at a considerable distance from the instrument solve that problem.
Such systems are peculiarly valuable to the theatre — much more so than to other businesses, where employe activity can generally be interrupted without harm.
Talk-A-Phone Company of Chicago have announced a complete post-war line of loudspeaking communication systems, so designed that an employe can hear and answer a call without touching the instrument, and while remaining at distances up to fifty feet away from it.
There are fourteen different systems, so flexible in application that one or another of them can meet the communication needs of any theatre from the smallest to the largest.
Any number of stations, from two to one hundred, can be provided. Arrangements can be included whereby any station can call any other station (regardless of whether or not the station called

has its power turned on) ; or the system can be so set up that only some stations are able to originate calls, while others are limited to answering when called. Provisions can also be included in the more elaborate systems for "conference" talks in which any selected group of stations participate; and for a number of different conversations to be held simultaneously over the same network without interferring with each other.
Paging and announcing provisions can be included in the larger systems.
All equipment works from 110-volts, a.c. or d.c. Sub-stations also can be provided that need no power and therefore can be located without regard to proximity of a power outlet. (#12).

EJJElTMiL? CONTROL PROJECTION LAMP
Oscar Oldknow, Vice-President of National Theatre Supply, has returned to the Coast after a short visit to New York City. (#13).
A new and highly acclaimed development — ELECTRONIC CONTROL — makes present mechanical systems of feeding the positive and negative carbons in projection arc lamps oldfashioned and obsolete; assures faultless arc control of precision accuracy, maintaining the proper focal point necessary for producing maximum light intensity without the necessity of constant watching and adjusting. Eliminates cams, gears, clutches and associated gadgets.
