Description:
Moving Picture World, founded in 1907 by J.P. Chalmers, was one of the motion picture industry's first trade papers. Published on a weekly basis in New York City, Moving Picture World informed exhibitors about films available for rental and editorialized on behalf of the growing industry (improving the quality of movies through higher filmmaking standards, not government censorship, was a frequent topic). The paper reached its height in the mid-to-late-1910s--a fact reflected in the circulation figures and the huge amount of advertising that filled every issue during the period. In the 1920s, Moving Picture World lost ground to other competing weekly trade papers -- including Variety, Exhibitor's Herald, and Motion Picture News. In 1927, Moving Picture World ceased publication when it was acquired by Martin Quigley's Exhibitor's Herald. Across the 20 year run of Moving Picture World, readers can watch the transition from short film programs to feature films and witness the transition from the dominance of Edison's Trust to the rise of the "Independent" film companies that ultimately became the Hollywood studios. Silent film historians have utilized and cited Moving Picture World more frequently than any other trade paper, and the publication still has many insights left to offer. -- Eric Hoyt, 2012/2013

July 27, 1918 THE MOVING PICTURE WORLD 607 i. n Discrimination and Conservation We desire to announce that within the past two weeks we have had offered and submitted to us for test, a comparatively cheap device intended to change Alternating into Direct Current. We were pleased to be told by the manufacturer of this device that he considered us the largest and most responsible distributor of motion picture accessories, and that he hoped the test would prove his device to be equal to a motor generator. We have stated how U. T. E. is composed of the most experienced men and engineers in the business. Therefore, it did not take us long, after we secured the device, to find out that, although it was advertised a few weeks ago as a "Converter" of A. C. to D. C, it is merely a commutating rectifier. The mechanical commutating rectifier has been experimented upon and proposed for many years, and we were somewhat surprised when certain claims were made for this device, and now our judgment has been verified, and that is — That a mechanical Rectifier with commutator and brushes, operated by a synchronous motor, will not give a constant Direct Current source of supply for the arc. Therefore, in order to produce a light on the screen which is at all satisfactory, it is necessary to run at very high amperage on the D. C. side. Tests proved conclusively that a 55 ampere D. C. Arc on a Hallberg Motor Generator gave onethird more illumination on the screen than was produced with this so-called converter with 80 amperes. But, aside from the efficiency being 8% lower than the poorest motor generator, and being from 15% to 18% lower than the efficiency of our Hallberg Motor Generator, and the light one-third less with the same watts consumed from the line, the most important feature is that a mechanical rectifier or so-called converter delivers an interrupted current at the arc. Therefore, the ghost or wave effect on the screen is apparent, like it is with the ordinary A. C. arc — If U. T. E. had not exercised its usual discrimination in selecting the articles it offers for sale the low price at which this device was offered to us might have made us offer it for sale to you — Mr. Exhibitor — You can thank your lucky stars that there is at least one equipment concern which is not subject to influence by low prices, but Quality takes first place with us. In the above, U. T. E. has exercised Discrimination. Now, it is up to you to exercise Conservation, by saving current and producing better results on your screen, by installing our Hallberg Motor Generator. We guarantee absolutely satisfactory results with the highest efficiency. "EVERYTHING FOR THE M. P. THEATRE EXCEPT THE FILM' United Theatre Equipment Corporation H. T. EDWARDS, Pres. J. H.
