Ashcraf t Marketing New Copper Oxide Rectifier Ashcraft lias introduced a new Copper Oxide Rectifier which, according to the manufacturers, is one of the most efficient means of converting alternating current for the operation of Suprex projection lamps. Properly designed and constructed, it is said to be one of the most dependable means for rectification. According to the manufacturers, whose plant is located at 47-31 35th street, Long Island City, N. Y., the Copper Oxide Rectifier consists of four distinct units: — the case, the transformer, the exhaust fan and the copper oxide unit. Each unit, though having an individual function, is coordinated with the others in such a manner that the ensemble operates with maximum efficiency and dependability. Although the rectifier is mounted in a case of generous proportions — larger than other motion picture rectifiers — it takes up no more floor space. The additional size of the case allows a more evenly distributed flow of air through the oxide unit. New Oil Drive Take-Up Offers Advantages to Projectionists At the recent convention of the Society of Motion Picture Engineers in Hollywood, the new Golde Oil Drive Take-up occasioned much comment, being hailed as filling a long-felt need for the completion of projection machines and projection safety. The new Take-up is a totally enclosed device and has in its enclosure an oil shaped disc driven by the enclosing case entirely filled with special oil and permanently sealed. Its design is said to assure the same smoothness for the life of the projector and without adjustment. The initial adjustment that is sealed will provide for taking up film up to 2,500 feet without intermittent wear on Take-up feed sprockets or film. Weber Offers Newly Designed Gonstant Speed Sound Head Weber Machine Corporation, among the pioneers in the theatre sound field, is now marketing a newly designed magnetic filter which the company's engineers claim to be a revolutionary forward step in the reproduction of sound through the maintenance of constant speed of projection and reproduction of the sound track. The magnetic filter, a patented device, has approximately 40 pounds of "fly wheel" balance. Features claimed for the filter by its sponsors include the maintenance of unvarying speed, from the start of the film to its end with uniform motion past the light slit. Magnetic Filter recently developed by Weber Machi.ne Corp., is now a feature of that company's Syncrofilm sound head, illustrated above.
