SUBJECT : Establishment of Department ot the Army, Project lNl!lber 

29•43-011, Cycle Analyzer, ASAF 30 as a Service Project 

1. Purpose 

In tha development of new crypto-equipments tor the Arq Field Forces and 

the u. s. Air Forces it has become necessary to construct a device that will analyze 

cycle langth~ ' 

2. Description 

This equipment will be used to generate a~ e~:.ar:ine euccessiv~ time pulse 

distributor positions produced by interconnecting numb9rous title pulse distributors 

in various ways. It will be capabl_e of du;;>licating th9 stP.'.'Jping r:.otiono of most or 

the known or proS)'.'lective rotor r.:r.chings. lt wilJ autor.ati..celly searcl· .:"or a duplication of any of ita nreviously g~n~rated settings, to det.~rrnine .... hen the system 

has begun to recycle. It will lndicat~ t~e length of the cycle and th~ approximate 

lengtl· of lead-in until the syster.: re~Jcles. 

3.. Related lliaterials or ft.ethods 

There are no materials o:r methods related to this device ncnli being used · 

at Army.Security Agency. 

4. Deyelonment History and Statue 

Circuit e and principles useCI. in the project "i'JRIRll'.IND", a U. s. Navy 

device no;1 at the Massachusetts Institute of Technology will be used in the manufacture or this device. 

s. Proposed Develonment 

The first phase will be to dealgn and construct. one prototype model ot 

each of the components required in its overall construction. The second phaae 

will be the construction testing or t.he overall device. The third phase will be 

the addition ot automatic input set up and out-put loading accessories, and the 

installation of the equipment at the Army Security Agency. It is proposed to 

build one each ecuipment starting about 1 April 1949, and complete service tests
