Capacity current rectifiers with silicon stacks have been placed on the market by Doc Faige & Associates, New York. Announcement of this type of eejuipment for conversion of a. c. to d. c. to supply projection arcs states that it is available in capacities up to 180 amperes. It is pointed out that the silicon stacks are relatively small and can be operated at such high temperatures that blowers or fans are not necessary. Efficiency is rated at 15-20$ greater than that of other types of conversion, allowing, it is said, a saving in current drawn from the a. c. line. File stacks are hermetically sealed, which is cited as protection from dust and moisture, while ability to operate at relatively high ambient temperatures permits small ventilation openings, minimizing collection of dust in the unit. Field tests, it is stated, have indicated long life expectancy of the silicon stacks. 11011-toxic, in addition to being nonflammable. It was pointed out further that the compound will not soften magnetic striping or cause warping of the film base. Cut-Proof Seat Bottom Of Woven Steel Alloy A SEAT BOTTOM of WOVen steel alloy, developed especially for replacement of theatre chair seat bottoms where they are subject to mischievous cutting and similar damage, has been added to the line of National Theatre Supply. Called the “Texteel No-Cut” seat bottom, it has the appearance of finely woven cane-bottom chair seat. An incidental advantage cited is coolness in hot weather and in climates consistently warm and humid. Two Admission Control Systems Added by NTS two new systems for admission control have been marketed by National Theatre Supply, one for driveins, one for indoor theatres. The drive-in system, developed for National by the General Register Corporation, provides for mechanical registration, with counterchecking features to give a complete record of admissions without possibility of tampering and collusion. The indoor theatre method called a “2x1” ticketing system, consists in a twopart perforated ticket with each ticket number in sequence for checking against registration of cash receipts. The tickets have holes punched in them so that they slip on to a rod and remain in sequence. MAGNETIC FILM CLEANER Freon1 13 (trichlorotrifluoroethane), originally developed as a refrigerant, has been found to lie a safe and efficient cleaner of magnetic sound film, according 10 the I)u Font Company. Chemists al the Du Pont laboratories have declared that the compound is relatively THIRD ALTEC-LANSING PLANT Ground-breaking ceremonies mark start of construction of a new Altec-Lansing sound equipment factory at Anaheim, Calif.
