International projectionist (Jan-Dec 1946)

New FS-10-N Kodascope An Advanced 16-mm Equipment FS-10-N, Kodak's top-quality, 16-mm sound Kodascope is now making its appearance in new dress — two convenient, smartlyengineered units, instead of one. Designed for versatility and carrying ease, the new cases now hold, in one, the speaker unit, 50 feet of cable on cordomatic reel, a 1600-foot take-up reel, spare projection and exciter lamps and fuse, power cord, and oiling outfit; in the other case, the projector itself plus the reel arms. Case one, the speaker unit, weighs approximately 25 lbs. And case two, the projector, weighs approximately 47 lbs. Both cases are finished in black boar-grain Kodadur. Easy to set up and easy to use, each unit is readily packed and unpacked. The speaker unit need merely be plugged in and located near the screen. The Kodascope may be set up in the case with the cover swung open or may be removed entirely and seated atop the case, or alone on a table or other base. Everything needed for a showing, except for the screen, has a place in either the speaker or projector case. New Ampro 'Century-10' Features Compact Quality, Economy Making projection of 16-mm, sound-onfilm movies as inexpensive as possible, while retaining all the precision features necessary for quality sound projection, is the announced purpose of the new Amprosound "Century-10." This light and compact projector with extremely simplified design provides the utmost in 16-mm sound-on-film projection where such features as still pictures, reverse operation, and the combination of silent and sound speeds are not desired. With its constant speed a.c. motor with film speed of 24 frames per second (.sound speed), the "Century-10" is adapted for use in homes, classrooms, in small auditoriums and for industry. Fast automatic rewind, easy threading system, quick-centering tilting knob, and centralized panel control are a few of the convenient features. Standard prefocused lamps up to and including 1000 watts are used. Micrometric lamp adjustment aligns the lamp filament with optical system both laterally and vertically. Projector is equipped with 2-inch, //1.6 coated lens, instantly replaceable by either 1, 1%, 2%, 3, 3% or 4-inch lenses. For Medium-Size Auditoriums Among the features is the rotating type of sound drum which avoids sliding action between the drum and film, thus prolonging film life and maintaining high quality sound. Also provided are curved film guides before and after sound drum which eliminate weaving and "belt action," tone control, and a 12-inch p.m. dynamic speaker. The "Century-10" operates on 60 cycles a.c. only, 105 to 125 volts, although it can be used with a converter or invertor on d.c. Complete unit includes projector, speaker, lens, lamps, 1600-ft. reel and standard accessories. Two carrying cases are also supplied, for projector and speaker. Other specs are available from Ampro Corp., 2835 No. Western Avenue, Chicago 18, Illinois. New Eveready 'B' Battery Has Vi Size, Weight of Old Type EVEREADY T EVEREADY Standard LAYER-BUT A new 45-volt B battery having only half the weight and size of pre-war models has been developed by "Eveready" Batteries for use with electronic industrial test equipment, portable amplifiers, radio transmitters, commercial motion picture projection machines, electronic and telephone devices, etc. The new battery utilizes the famous "MiniMax" battery principle originally developed to power the tiny radio sets in the proximity fuses of anti-aircraft and artillery shells, and is the most efficient storage power source ever evolved, according to battery engineers, since it employs a higher usage of space by active materials than any previous type. Round batteries have a carbon center post set in a zinc can with activating chemicals packed between. Old-style layer-built B batteries have piles of alternate zinc and carbon plates separated by layers of the chemical mix. The "Mini-Max" battery has the carbon electrode printed ink-thick, in effect, on the zinc plate — which greatly condenses the size and increases the efficiency of the battery. TRADE UNIONS IN AMERICA (Continued from page 23) mind. On several occasions when the Senate took action which jeopardized the crafts, they struck, marching out of Rome in a body. They stayed on the other side of the Tiber until the Senate receded from its unacceptable position. What took place in Rome had developed in other lands, for there are in existence proofs that the ancient craftsmen of China, Phoenicia, India, and Egypt organized craft unions. As craft organization was a natural development, craft unions were probably organized in other ancient countries, but with little if any evidence remaining to record the fact. Because the Roman craftsman was a free man, a citizen with full citizen rights, and Rome became an empire, the Roman craft unions developed to a much greater extent than in any other country. We know but little of the Chinese craft unions, for their history, if mentioned by ancient Chinese writers, has not been made available to Occidental students. This is regrettable, for Chinese workmen claim that some of their craft unions are several thousand years old. It is known that many of their craft unions today maintain customs based upon old traditions and forms, both as to the union's attitude toward the employer and the apprentice. Reports come from Southern China that some unions have a dominating control of the workshop. The employer does not enter his shop without first receiving the shop committee's permission. He does not select his foreman; that is done by the union, the foreman being determined by the size of the shop, the largest having the union's president, other officers in turn filling similar positions in the smaller shops. It is the union which largely determines the terms of employment and the conditions of labor, who shall be employed and who discharged. The employer's attitude is one of seeming satisfaction. For the wages paid, the craftsmen must deliver a stipulated amount of good work. While the employer does not hire or discharge, the union is wholly responsible for good performance and the maintenance of order and discipline. The employer is saved all effort to maintain management and adjust disputes. His concern is the securing of raw materials and the sale of his finished product. Apprenticeship is for seven years. When an apprentice has shown sufficient aptitude he is initiated as an apprentice. Then for each succeeding year he must live for three months in tbe home of one of the members, the last being the home of the foreman. All this results in increasing his craft skill and acquainting him with the customs and traditions of the union into which he is finally initiated as a journeyman.
