Approved For lase 2002/08/06 : CIA-RDP78B047472400050021-8 STAT SUBJECT 9-1/2" BLACK AND WHITE file (2) PROCESSOR MODIFICATIONS The following changes of the 9-1/2" black and white processor are the approaches we are planning to produce a Proper iv runctioning system. These changes will enable us to process film 1. Replenishing System The replenishing system will consist. of replenishing tanks suf- ficient in size to process 500 feet of film. .(Figure 1) These tanks will be installed above the processor which will provide the required head pres- sure to operate the flow meters. Each processing module will be modi- fied by the addition of overflow stand pipes. The replenishing tank sup- ports will be permanently mounted. on the processor. The replenishment tanks shall be detachable for ease of maintenance. Each tank will be furnished with a lid to reduce aerial oxidation and evaporation. 2. Dryer There are two possible design approaches to the drying problem which shall be studied. A. The simplest modification appears to be the addition of a second infra red source which will be installed so that the radiation is applied to the emulsion side of the film. (Figure 2.) Approximately one-half of the existing air knives will be removed to facilitate the install- ation of a second infra red source... The existing cooling system should be sufficient to accommodate this additional load. It may be necessary to provide a second voltage control unit. B. The second design approach will require extensive modifica- tion to the takeup end of the processor. These modifications will con- sist of removing the infra red source air knives and supporting equipment. This system as shown in Figure 1 will be.of the heated air impingement plenum type and will consist of three air plenums and the associated Declass Review by NIMA/DOD Approved For Release 2002/08/06 : CIA-RDP78BO4747AO02400050021-8 STAT STAT STAT STAT.

As this type of dryer will require more air, the existing blower will be used for the wet section only, further reducing carryover. An additional blower will be used for the dryer section. This dryer blower will be housed inside the available space under the vacuum capstan, therefore no. increase in processor length is anticipated. (Figure 3.) 3. Temperature Indicating System The temperature indicating system will be tested for accuracy and reliability. If the present system proves unusable, it will be re placed with a thermister operated system. The Film Transport Indicatincr System, The film transport indicating system' will consist of an independent tachometer and a PPM indicating meter mounted, adjacent to the speed control knob on the front panel.

Further testing will be conducted to,establish replenishing rates for 70mm and 9-1/, " film widths and drying parameters required to properly pro- ce$s.500 foot rolls WJI/trb STAT Approved For Release 2002/08/06 : CIA-RDP78BO4747AO02400050021-8 Approved For Release 2002 08/06 : CIA-RDP78B04747A002400050021-8 R.EP E.htt; - IY1Ft,1-T J\A?IOtFtCATtcSN Approved For Release 2002/08/06 : CIA-RDP78BO4747AO02400050021-8 Approved For Release 2002/18/06 : CIA-RDP78B04747A002400050)1-8 ADDITIONAL I NFibP-ED 1 {" FA ED D' ~1U t t ~' Q 4 Approved For Release 2002/08/06 : CIA-RDP78BO4747AO02400050021-8 Approved For Release 200208/06 : CIA-RDP78B04747A00240005021-8 PLE.WUN1 'DRYER M6WFICATkOiAS Approved For Release 2002/08/06 : CIA-RDP78BO4747AO02400050021-8 Approved For Release 2002/08/06 : CIA-RDP78BO4747AO02400050021-8 Dear Ray - Please let me know if you concur with this program.
