five of these are used for each telephone subscriber, so that the total number produced each year is of the order of five million units. Here again, small savings, either in the cost of the relay, its maintenance or in a reduction of the operating time of the relay, have a high economic value because a large number of them are produced and used each year.
Another view of the value of highspeed photography in Bell System research and development work can be taken from the fact that about 700 to 800 100-ft reels of high-speed motion picture film are taken each year. Most of these are carefully studied, frequently by a group of engineers. From these studies, conclusions are reached which result in new and better understandings of the devices and frequently design changes or new designs are the result. Faster processing service of the film would be helpful in expediting development work.
The exact dollar value of the engineering manhours and materials which
have been saved by the use of high-speed photography is difficult to evaluate but it is obviously very large in important research and development activities. On one particular project of a device made in large quantities for telephone use, the project engineer estimated that savings of several hundred thousand dollars a year had resulted. Other projects have saved much less and some have shown even larger savings.
In closing, I would like to say that there are many other economic advantages in the use of high-speed photography in maintenance problems, training problems, etc., which I have not touched upon in outlining the engineering value of this tool in research and development work. Our daily use of high-speed photography, leads us to expect an expanding application of this new and important engineering tool and as a result will make better use of that most precious commodity — engineering manpower.
