Approved Forilpase 2004/05/13 : CIA-RDP89B00941,00400090002-0 sUMNA000, ACTIVITY 29 i;ct. 5 DO4# The following tests verde completed: T4 ? Autobalamce Purpose: determine if autobalance is neeueu. Conclusions autobalance is nee(Jed, occoruiag to the subeentroctor. Actually, the test proved only that the conligmration goes out of hatmace it there is no pitch autoisalaace. It did not ascer- tato if the cause oi imbalance could WA removed mot that the astehalaace was adequate to correct imbelameei T5 ? Position Servo Purpose: teat position servo over range 35 ? 110'i. Coaclusions performance satisfactory, according to H. Purpose: detonable it IMC command voltage is 6istorted, an iocats distortion cause Li existent. Coaclusion: IMC command voltaic is mot distorted, according to the subcoatrector. Actually, rev (Alta shows voltage diatertIosE the test methou was poor, and the satire test should be rerun. ' (A cheek La Groumd Ems fl shows distortion exists') Ti LITS Satire Vibe Drive Mechanism & System Purpose: learnt tor wear. ' ConclusiosW only the vacuum solenoid slug showed wear, mid this was *Light. At the present tine, the fits drive mo_loeser operates satiatec- tartly it throws a tile loop fsequemtly. The satire film drive was retested by the eubcoatraeter. 79, T15 & T16 - Shatters Purpose: tor three ditiereut shutter modifications, determine vihretion levels and frequencies, double exposure character and parts subject to wear. Conclusionas all modifications showed,simtlar characteristics. 30,000 cycles with few double exposures now is possible. Vi- lorstihh data needs comparisoa with previous dote. A modification is now being made to tour shutters so all, will be alike. CLASS. El "?''' "N?

Conclusion; vacuum solemoid causes vibration in scanning ilat and its mount; mod an improved solenoio is needee. The pitch /texture transmits negligible vibration along axis of the plunger. 122 ? Autobelasse Malfunction Purposes deteemlme why autobalanose will not compensate ier at end low condition. Conclusion: potentianster R23 was accidentl sis-edjusted. 12.3 - Optical Elements Purpose; locate optical elements causing poor image as *widowed on photographic plates. Conclusion; poor image results true distortion at collbnated source because of air layering ago turbulence. Also, project collimators *Wald be tasted in sornal operettas position with an auxiliary flat, not by rotating eellbnator's own fist. 124 - Cages Purposes determime cause of eager solenoids failure to rsooao when configuration IA turned to standby.
