Williams Producing Screens 9 Years By John Morgan vice-president, Williams Screen Company Williams Screen Company is begin¬ ning its ninth year of producing all¬ vinyl plastic screens, and according to H. C. Williams, president and inventor of this screen manufacturing process, is oper¬ ating its two plants at full capacity. An important exclusive of Williams Screen is the applica¬ tion of the finish by automatic machinery to produce an em¬ bossed surface. A disk-shaped indent¬ ation surrounds each perforation to serve as millions of tiny reflectors over the entire picture surface. The em¬ bossed design furnishes proper light distribution for all viewing angles and eliminates the objectionable “hot spot” which is frequently associated with an ordinary silver screen. The silver finish on a Williams screen is infrared baked at high tem¬ peratures to assure a tough finish which is resistant to abrasion and abuse and gives the screen long life and durabil¬ ity. This finish is another Williams ex¬ clusive. There are no seams to mar the pic¬ ture since the entire screen is welded into one piece. The clear, even silver surface is free of streaks and discolor¬ ation. Each feature has been carefully designed to make it ideal for all the different types of picture presentation. Williams Screen Company, manufac¬ turer of motion picture screens since the advent of the first sound screens 27 years ago, introduced their all-vinyl plastic screens several years before any other company. Since then other manufacturers have adopted vinyl plastic for screen construction. Distribution in the United States and Canada is handled direct by Williams Screen Company’s two large plants in Akron, O., or through the Ballantyne Company dealers. Exports to other countries are made through Streuber and La Chicotte, Inc., New York. H. C. Williams Selenium Conversion Toledo, O.^ — Production of a new KniTron conversion unit for converting tube type rectifiers to Selenium, at half the cost of new equipment was announced by The Kneisley Electric Company. The unit, a complete package for simple installation, consists of Selenium stack, fan, fan motor and stack housing, with all necessary wiring and detailed instruc¬ tions. Complete change-over from tubes to Selenium takes only 20 minutes and is eaaly done in the projection booth, ac¬ cording to the manufacturer. Because the transformers and housings incorporated in present tube type rectifiers are essentially the same as those required This Kni-Tron unit from Kneisley Electric is a complete package which makes it possible to convert tube type rectifiers to selenium units. for Selenium, it is possible, according to Kneisley Electric Company engineers, to convert almost any type of tube rectifier to Selenium at low cost. They further state that the use of Selenium increases efficiency 17 per cent plus. The fan ex¬ hausts 1500 cubic feet of air per minute over the Selenium stack, providing forced cooling for both the transformers and the Selenium stack, resulting in exceptionally cool operating temperatures and greatly increased capacity. Admission Control System (Continued from page PT-10) recorder which notes and totals the data. The complete log of all transactions in each of the theatre’s entry lanes is kept in the recording machine for that lane. This recorder has five counter wheels which record, and print on paper tape whenever desired, the following infor¬ mation: month, date, and hour; lane number; total paid admissions, total pass admissions, and total automobile axles passing over the treadle. The number of transactions recorded by an attendant on his control panel must therefore tally with the number of cars counted by the treadle. The totals of pass and paying customers must also tally with the total number of passengers recorded on the overhead indicator. As a further spur to honesty, the attendant has no way of knowing the amount of dollar receipts indicated at any given moment on the locked totalizer — to which no one but specially authorized persons can have access. Consequently, each at¬ tendant must turn in the full amount of cash he has collected or risk immediate detection.
