NEWS AND VIEWS OF THE MARKET AND ITS SOURCES OF SUPPLY Large Display Case With Sliding Door large poster cases, for a series of displays without interruption, or for over-size displays, are now available ready for mounting from Poblocki & Sons, Milwaukee. The company announces: "We have received many requests for large size poster cases and instead of furnishing double 40 x 60 or double 40 x 80 cases, we are now furnishing a large case with a sliding door. This will have the effect of a large show window and eliminate series of cases with a break between each case." The large cases, like the company's standard sizes, can be had in either extruded aluminum or polished stainless steel, and in any length or height. Drive-In Sound Systems To 1000Watt Output amplification systems designed specifically for drive-in theatres, with outputs ranging from 140 to 1000 watts, have been brought out by the Theatre Equipment Section of RCA. They form The left hand rack is of amplifiers for the PG-275 drive-in sound system, which has an output of 140 watts. The other is the 1000-waft amplification cabinet for the PS-287 drive-in sound system. two series, one called the "High Power," the other the "Super Power," and the two groups, states J. F. O'Brien, sales manager, "enable operators of every size of drive-in to select the exact system for their individual needs." The announcement points out that each group is planned to permit starting out with a small power output and to build up to greater output, as conditions require or allow, by installing additional amplifiers. With the new equipment, the number of sound systems in the RCA drive-in line has been increased to eleven. Deluxe Type Magazines Added to Wenzel Line new projector magazines with a number of special features designed to make them superior to the company's standard models, have been added to the line of the Wenzel Projector Company, Chicago. According to specifications released by the manufacturer, the new 18-inch magazines are %-inch deeper on the rear wall, allowing practically T%-'ncn between reel and wall. Shafts on both upper and lower magazines are J^-inch in diameter through the length of the bearing surface, while the bearing surface of the upper magazine is inches long, and that of the lower magazine is 4-1/6 inches. Upper magazine shaft area carrying tension adjustments remains jHi-inch to accommodate reel end alarams designed for such diameter. The need for lubrication has been minimized by having the upper magazine shaft run in two flanged oilite bearings, which are pressed in from side of the bracket to leave a slight gap between the two inner bearings ends to serve as an oil reservoir, and the manufacturer states that only a dash of oil every few weeks is necessary. With the steel collar on the reel shaft and the steel collar in the tension spring, operat ing against oilite bearings, uniform wear is provided for. The lower magazine runs in a hardened and ground steel bearing. For these new magazines special aluminum brackets are provided, and the door opener is also of new design, while the window is framed in nickel. Further, the spring tension brake drag is of new design in both upper and lower units. Finish, like that of the older 18-inch and the 24-inch, which are retained in the line, is baked gray wrinkle externally, and baked white enamel inside. "Package" Dimmer with Six 8 50Watt Circuits new light dimming equipment of the "package" type has been announced by the Superior Electric Company, Bristol, Conn. Having portability comparable to that of the "packaged" theatre dimmer marketed about a year ago, the new unit has six circuits. Designed for application to the dimming of auditorium lighting in small theatres, with maximum simplicity and economy (and it can be used as well for small stage productions), the new equipment, listed as DBR6-850, has six auto-transformer type dimmers, each having an output of 850 watts, mounted in a wrinkle finished case. These dimmers are non-interlocking. The manufacturer explains: "The assembly operates from a threewire, single phase 230/1 15-volt, 50/60 cycle source. Each of the circuits has an output range from 0 to 850 watts. A separate fuse protects each circuit." Individual on-off switches are provided for each circuit, and highly legible numerals are imprinted on chrome-finished drums. BETTER THEATRES. DECEMBER 18, 1948 n
