Abstract: An improved method for removing and collecting plating wax from waxed components such as turbine engines components from aircraft, and an improved collector for reducing this method to practice. Collectors known in the art generally have 1) a process tank filled with a remover solution into which the waxed component is fully immersed and the wax is removed; 2) a wax separator tank connected to the process tank for receiving therefrom an overflow of remover solution and removed wax; and 3) a circulating pump for pumping the wax remover solution from the wax separator tank back to the process tank. The collector of the invention further has a level controller operating with microwaves for monitoring the level of remover solution in the wax separator tank and a chemical pump connected to and controlled by the level controller in order to maintain the level of wax remover solution in the wax separator tank close to a preset level by pumping a new batch of remover solution in the wax separator tank.

Abstract: A method for detecting the presence of any discontinuity in an anticorrosion oil coating applied onto the internal walls of a nautical ballast. The method comprises the steps of (1) adding an oil-soluble tracer to the anticorrosion oil coating prior to its application onto the internal walls of the ballast, the tracer being insoluble in water and rust; inert to rust, water and the oil; and capable of emitting visible light under the effect of a black light; (2) after application of the oil coating, submitting the inside walls coated with the oil to the effect of a black light, and (3) checking the continuity of the visible light that is emitted by the oil coating, whereby the presence of oil is detected by visible light emitted by the tracer and its absence is detected by the absence of any emitted visible light. An anticorrosion oil containing such a tracer is also disclosed.
