JANUARY I8TH, 1945 FLIGHT Advertisements. 7 CECO ENGINEERING AT WORK IN WAR AND PEACE PENNIES PROTECT MILLIONS Protek-Plugs •• the Modern Moisture Removal Method It began with aircraft engines. Once, it took many hours to remove the grease that was necessary to protect the cylinders of engines in transit. Ajb Today, Protek-Plugs are removed from the spark plug openings, the spark plugs are installed, and in minutes, the engine is ready for service. Protek-Plugs are hollow, transparent plastic containers, filled with Silica-gel, a material practically chemically inert, with a tremendous capacity for water. They remove corrosion-producing moisture from the cylinder walls by adsorption. When the Silica-gel approaches saturation, the plugs signal "Danger" as their color changes gradually from bright blue through violet to pink. The spent plug is then replaced with a fresh Protek-Plug. . Protek-Plugs are at work today by tens of thousands, not only in aircraft engines, but in delicate mechanisms of all kinds. There is ample proof of their value from every battle front. Costing pennies, they guard vital war equipment worth millions. Tomorrow, this war-born product will protect more than the engines of aircraft in transit and in storage. It will find dozens of other jobs guarding the commerce of peace from moisture damage.
