The Exhibitor (1952)

Fire Extinguisher Designed for all type buildings, but especially recommended for outdoor use — with an anti-freeze charge when subject to freezing temperatures — a non-invert¬ ing, pressurized, water-type fire extin¬ guisher recently was introduced by The General Pacific Corporation, Lcs Angeles, and The General Detroit Corporation, Detroit. The manufacturers point out that in¬ experienced operators can use the extin¬ guisher easily because of its squeeze grip and “panic-proof” rip puncture pin which insures discharge, once the seal is broken, regardless of the position of the handle. Shell of the unit is made of seamless drawn brass, and all component parts of the head assembly are of brass. All parts of the extinguisher are remov¬ able as a single unit, thus affording a special recharging feature. The charge consists of water and a pressurized carbon dioxide cartridge.

FEATURE 1 — The sensational Dub’l-Cone 4" Speaker (Fig. 1. A). Consists of two cones, one superimposed over the other with a 3/16" air space between. The outside cone for protection, the inside for projection, of sound. Both cones are completely weather¬ proofed by the latest methods. The sun can dry or bake out, water can soak, and the outer cone can go to pieces without damage to the inner cone. If the outside cone ever becomes destroyed it can be replaced with' a new cone and ring by the drive in theatre owner in a few seconds . . . and have a new speaker for less than 20 cents. FEATURE 2 — INCOMPARABLE QUALITY SOUND. Has a Heavy 1.47 ounce Alnico 5 Magnet (Fig. 1, B) which gives 2 to 3 times the power of earlier magnet materials. This plus the sounding board effect of the protective cone and air space produces sound that is more completely developed in the lower frequency than ordinary speakers and gives a full round tonal effect to both music and voice. The life-like sound reproduced by this speaker more closely resembles theatre sound than anything heretofore available. FEATURE 3 — Aluminum Voice Coil (Fig. 1, C). The Voice coil is aluminum . . . will not swell, warp, or buckle. Retains its shape thus maintaining the vital delicate air gap around it. FEATURE 4 — Alumizite treated diaphragm. (Fig. 1, D). Impervious to rain, dampness, sun and heat. The only speaker on the market, with treatment of any kind at this vital point. FEATURE 5 — Die Cast Aluminum Case in two tone finish. The case is die cast of aluminum for strength, lightness, and durability^ and has a beautiful two-tone finish. Both colors are double-coated and each coat baked on. It is truly the most beautiful speaker on the market. The junction box is also finished in the same twotone effect. FEATURE 6 — Every point in a speaker that can be attacked by water or dampness has been protected in the Ballantyne AX Series Dub'l-Cone Speaker. OTHER OUTSTANDING FACTS about the DUB’L-CONE SPEAKER — • All metal parts are zinc-plated by a special process. • Cones, gaskets, and dust buttons are treated with a fungus and weatherproof lacquer approved for use on Signal Corp equipment. • Gaskets are punched out of solid beaverboard to eliminate split¬ ting as often happens with laminated chipboard normally used. • A Brass dust collar completely eliminates any possibility of cor¬ rosion. • A high quality, enclosed, wire-sound volume control is used. • The junction box transformer is varnish impregnated to guard against moisture.
