The service uses a patented, precision machined code press and matching plates to emboss small indentations on the frame lines of film. The never-duplicated code is unable to be copied and will prov ide positive ^identifying marks for film libraries, producers, schools and others to prevent loss, "straying", theft and print-switching. Each subscriher leases the code press and plates to mark the films in his library, and the "branding" is good for the life of the print. Each subscriber to the Film Identification Bureau services will have his "brand" registered for quick, positive establishment of ownership. Every year tens of thousands of feet of valuable film are lost, mishandled, shipping labels removed, improperly mailed, even "accidentlv" switched. This FIB service will quickly get the right print back into it"s owner's possession, so it can quicklv become available for rental or showing. Films can be "branded" every 75-100 ft., in addition to the leader, so that it will be impossible to remove the marking without ruining the contents of the film. Special leader material with imprinting is available from the Film Identification Bureau, or subscribers mav use their own leaders and tails. iP International Projectionist January, 1965 TAKE YOUR PICK 0/ the 2 means of power conversion for projection lighting. ^fatf BI-POWR Silicon Stack Rectifier for Operation off 2 Lamps ■ HEAVY ROTATING EQUIPMENT Costs considerably less than 2 separate low priced single rectifiers.
