CONCLUSION 



111 this and the accompanying articles we have given a partial picture 

 of the facilities for automatic testing in the Western Electric Compaiw. 

 At this writing several new machines are under development, and modi- 

 fications are in progress extending the application of some of the present 

 machines. There is a continuing search for new fields in which to apply 

 these techniques. A staff portion of the manufacturing engineering force 

 now devotes its full attention to automation techniques in general, keeps 

 abreast of the field, bulletinizes important additions to the literature, 

 lends assistance in the solution of problems, and develops specific appli- 

 cations. It is likely that the near future will see important extensions in 

 the use of automatic test equipment.
