S. both having so ruled. Fire Fighting Film Carbide and Carbon Chemicals Cor¬ poration, New York, has made avail¬ able a new 20-minute 16mm. sound movie in color entitled, “Fire-Fighting with Wetter Water.” The film is now available for showings to municipal, volunteer, and industrial firemen or groups interested in fire-fighting and fire prevention. The film illustrates how the com¬ pany’s new product, “Unox,” a fire fighting penetrant, makes water wetter enabling firemen to extinguish flames three to four times faster than previ¬ ously possible with plain water. It also shows tests, run throughout the coun¬ try by various members of the fire service, demonstrating the speed of knockdown and quick extinguishment of flames when “Unox” is added to water. Fire tests depicted include demonstrations of wetter water on fires in cotton, wallboard, wooden shacks, and various inflammable liquids. Typhoon Introduces New Evap, Condensers SMPE CONVENTION New York — During the recent 65 th annual meeting of the Society of Motion Picture Engineers, many topics, all perti¬ nent to the industry, were discussed. A get-together luncheon opened the festivities on the first day. SMPE members renewed old acquaintances, and the con¬ vention was under way. The following day, a banquet and cocktail hour was held informally, followed by a television con¬ ference. High speed photography also took a good portion of the meet. Sixteen milli¬ meter reproducer characteristics was an¬ other topic the group had under discus¬ sion, followed by a papers program, which included projection light sources, sound equipment, extreme aperture camera lenses, etc. A highlight of the conference was RCA’s demonstration of its latest equipment for theatre television projection. To install the equipment for the demonstration, it was necessary for RCA to construct a high, four-legged stand to hold the barrel-type projector. Barton Kreuzer, RCA, director of the demonstration, said his company “expects to be in position to manufacture professional equipment based on the shown system, in . pilot run quantities, possibly by the end of the year,” with expected price for a single unit to be less than $25,000. purposes and to the growing number of air-conditioning installations in areas where water is scarce, necessitated the need for evaporative condensers. The Typhoon units, says Don V. Petrone, sales manager, save 95 per cent of water costs, eliminate waste water disposal, are quiet in operation, and require minimum space. Many novel features of design, from the views of service and maintenance, should appeal to the theatreman. For example, the condensing coil in these units is all prime service, constructed of continuous lengths of seamless copper tube, pitched to allow rapid gravity flow of condensed liquid refrigerant. This feature combines with a carefully planned spacing of tubes to insure even wetting and intimate scrubbing contact of air to copper valves for a very high rate of heat transfer and minimizes scaling. Another feature is a redesigned blower, which blows dry air through the coil in¬ stead of drawing in moist air. For this reason, the Typhoon blower never comes in contact with high humidity air or any entrained moisture, and is not subject to danger of rusting, it is said. Furthermore, with this design, there is no “carry over” of spray in the discharged air. New York — James F. Dailey, president, Typhoon Air Conditioning Company, Inc., recently announced the introduction of a new line of evaporative condensers, the result of 40 years of research and manu¬ facturing experience in air-conditioning. The new evaporative condensers are made in three, five, eight, and 10-ton models, designed for use with freon, methyl chloride, or any other common refrigerant. The units are housed in a compact cabinet of fine furniture steel, with the spray sec¬ tion treated for complete rust resistance.
