210 Summary
l tisu Laminated Projection Slides
It is felt that improved projection slides for briefing
ise can be made by laminating the film to ,lass thereby eliminating
certain current problems. We will also look at the projector for
'field mou:ications to increase slide cooling.

In our discussion on 17 July about slide heating in
your large projector I mentioned a technique for lamination of
film on to a single glass plate. I find upon aaking questions
here that this has been successful only with the relatively soft
color film emulsions. The harder black and white emulsions are
not softened sufficiently by water to adhere to the glass plate.
I a process several years ago which a gelatin softening agent was used for successful lamination
of B & W film. We are submitting a Project Authorization Request
to to re-explore this process and to provide a small
lamination roller unit for your use if it appears successful.
We expect to explore both emulsion out and emulsion
in lamination of the film. The emulsion out situation will ve the
+ .sion vulnerable to scratches, However., your slides appear to be
ree*sbly well protected in than metal carriers and the silver
layer in which the heat is collected from the projector beam is
av*ilable for efficient cooling. Our hops in that with efficient
cooling the gelatin temperature can be held below the range
which causes it to shrink.
