The details of the reduction printer ,'ore discussed
with representatives of the procuring agency on
7 November 1958. The various questions that had arisen
during the subject report period roger:line reduction
rates, etaee izee and the like were clarified. The
Printer will be a fixed 2:1 reduction printer The
aperture of the film stage will be 19.P by 19em and the !
diapositive stage will be Vr" by 9i;". The spool
separator on the film side shell be variable in width
between the limitn of and P. Provision shall be
provided for the storage of exposed glass diapositives
by means of a suitable plate holder separate from that
required for exposure in the printer.
A nock-up of the printer light source was
demonetrated and found acceptable. Prints of the
fiducial mark configuration for both the two film and
single film operations were supplied. No nroblems
associated with these are foreseen at this time.

additiorial experimental work on the light source in

sight of the eleven stbessemblies in the rectifier
have leen completed and parts for the remaining three
are expected to be complete by the end of November.
The most critical portion of this part of the project
at .present is the completion of the schematic wiring
dine'ram by the electrical laboratory, which le a
rather complex job. , The electrical specifications
established could alee be the source of the limiting
time factor in completing the inetrument, depending
upon the delivery schedules of our vendors. This
completion date now appears to be sometime beyond the
end of the year.
The performance of the ptinter lens has not yet
been completely analyzed. A revielon of the light

eiarrently undn.vay, and will be completely evaluated
before the end of November, at which time the
