C^liARLF-S FORDVCE, superiiiiendent of Kodak's nianufac tin ing ex|)erimenis, told the SMI'E meeting that since early UIKi Kodak has replaced acetate |)ropionatc safetv film support with a new, improved "high acetyl" acetate ty|)e. Essentially the latter is made by retaining tlie chemical "acctvl groups" previously washed away in processing. Eordyce said considerable ex|3erimental work has been done on ihc new film to test it as a possible substitute for the cellulose nitrate variety now widely used lor |)rofcssional motion |)ictuies. "In addition to experimental tests." he said, "the new film has been carefullv watched through limited commercial trade use. S|>ec iai |)rints of scvx^ral features were cite iilated through film exchanges in dilferent parts of the country. .\lternate reels of safety and nitiate film were used in each |)rint selected lor testing and satisfactory quality was obtained in every respect." Safetv film generally is slowbmning. in contrast to rapid-burning nitrate film.

SINDIC inilin tensive laboratory tests, Fordyce cc)ncluded: 1) Low shrinkage of the new safety base will keep the film free from buckle and the resulting in and-out-of-focus images on the screen. 2) Tensile strength, rigiditv. and flexibility of the "high acetyl" film are more like nitrate film than previous safety bases. 3) Its greater resistance to mois ture and humidity effects means less procc-ssing trouble as well as less film distortion. •1) Projection qualitv. belter than that obtained with earlier safetv films, is ecpial to nitrate in screen steadiness and appearance. He added that new cements, manulactuied cspeciallv for use with the new film, will also maki satisfactory splices with nitrate oi older types of safety film. • • • GoldE Projector Line Given New Protective Finish C>>atings ♦ \ii .iiliaciive new look has been added to Gou)E projectors and spotlights. The companv has cieated a Sierra blown baked enamel finish to add beauty and durability to its prcxiucls. The Sierra brown finish in volves several baking o|x.Tations and is applied in three coats.

Redfield, president of Pinnacli PROt>i crioNS — protects and pr< serves motion picture film against abrasives, fingerprints and oils as well as heal or extreme cold. Ii mav be applied to aiiv film, nev\ or used, black and white <jr coloi . The process covers film with a tough coating that keeps it ttexi ble and protects the sound track. The coating contains no injurious chemicals. .\fter every Save-Kote applic.i tion, film is idenlified with a "tell talc" inditatoi— a red strip run iiing ihe lengili ol the film. This indicator shows the amount ol protective coating on the film The red band begins dlsap|H'ai ing alter i<|naiicl showings of tin prim, acting as a warning sign that the protec live coaling is wear ing.
