Each warning system consists of a cold-electrode, neon discharge lamp that produces a red aviation grade light. A cold electrode, neon discharge lamp warns aircraft away from high-voltage lines near runways. The low current draw prevents the hot spots that shorten the life of incandescent bulbs, and the sputtering that blackens the mercury discharge and metal halide discharge street lamps. As a result, the Balisor lamps have lasted longer than 10 years on high-voltage lines, for example, near Charles de Gaulle Airport in Paris. The Balisor lamp is equipped with a range of capacitive tappings to accommodate the voltage of the line being protected.
Various fittings provide needed suspension and insulation.
Obsta specializes in manufacturing warning lights for obstacles to air navigation, including buildings, chimneys, cooling towers, and bridges. European installations include Oy Soffco of Finland, Vimac of Portugal, and Vattenfall of Sweden. The static electricity that is unwanted in chic hairdos and sweaters is being used to temporarily bond films and papers in plants. Chargemaster Electrostatic Generating Systems, designed and manufactured by Simco Industrial Static Control of Hatfield, Pa., are finding their way into packaging, conversion, and laminating operations. The Chargemaster applicator is mounted in the Simco process machinery so the material passes by it.
