HOME MOVIES FOR MARCH 16mm Film With ilium Sound Track By DONALD W. ALDOUS Tech. Secy., British Sound Recording Association DETAILS of an interesting British development, known as the Varley Sound-Film System and developed by Martin Harper, well-known English film equipment technician, have recently been released. The primary objects of the system are to remedy the present position of 1 6mm. film, with its inferior soundquality (compared with standard 35mm.) and improve the perforations for moving film. The method enables a 16mm. film to be printed with a 35mm. sound-track « Two sections of recently developed British 14mm sound film which features 35mm contact-printed sound tracks. Film travels at standard 35mm sound speed, projecting every 2nd frame. At end of reel, film is not rewound, but screened again; this time, projecting frames omitted in the first run. Note novel perforation system for this purpose, also sound tracks on either side of picture area. in contact, as in the orthodox manner of printing 35mm. tracks, and the track is traversed at normal 35mm. speed, i.e., 90 ft. per minute, although the picture is projected at standard 1 6mm. speed. Of the 1 6mm. film width, 3mm. on each side is used for standard size sound-track. The perforations are of the same dimension and pitch as 35mm. but are so placed that the first two are side by side with the outer edges touching the inner edges of the sound-track space, and 8mm. down is a single perforation, of the same dimension, in the center; these perforations are continually repeated, thus appearing like a No. 5 domino. (See accompanying illustration.) The spaces 8mm. by 10mm. in between these perforations are thus free to receive the mute or picture part of the negative (which is printed by optical reduction in the usual way), excepting that the intermittent mech • Continued on Page 112 \ew Automatic 16mm Film Processor AF CONSIDERABLE interest to " 1 6mm. film laboratories, producers of 1 6mm. films, and i6mm. sound studios is the new Model 1 1 self-contained automatic 16mm. film processor developed and marketed by the Houston Corporation, 11801 Vest Olympic Blvd., Los Angeles, California. Model 1 1 is compact, portable, streamlined for top efficiency of operation and maximum ease for the operator; 64" long, 54" high, 24" wide. Model 1 1 has a processing capacity of 15' of reversal film per minute; 5' of negative film per minute, at 8 minutes' developing time; and 20' of positive film per minute at 2 minutes' developing time, Where developing tanks are used for negative and positive films only, without reversal solutions, such films may be processed at a rate up to 16' per minute. The machine is a completely selfcontained unit, requiring no addi Profits As Well As MoneySaving Offered in Compact Self Contained Unit For Laboratories Or Film Producers . . . Houston's new Model II 14mm film processor tional equipment. When connected to electrical power, water supply, and drain, it is ready for immediate operation. It is operated in white light. Film is driven by top rollers with floating bottom elevators to assure threading ease and uniform film tension throughout processing. Water jacket, solution tanks, super structure and power cabinet — as well as shafts, pipes, brackets, bearings, etc. — are all of stainless steel. Conveniently located is a control panel including stop-start switch, pilot light for flashing lamps, solution thermometer, speed indicator and footage counter. Drying is done by infra-red lamps, no a.c. is used. Amount of load is 4 kva. For concerns in all lines of business, the Houston film processor serves as an invaluable business tool.
