13.5 Conclusion 



In ending I should like to acknowledge the aid and useful suggestions 

 given me by Mr. C. E. Lane and my other associates in preparing this 

 article. I should also like to reiterate the fact that the status of the art as 

 described was reached after many years of pioneering development by many 

 engineers. In some cases the names of individuals associated with specific 

 contributions of a major nature have been mentioned.
