• Airlift — A technical installation, pump, or device based on the principle of pneumatic transport, used to lift a liquid or a mixture of water and sediments through a vertical pipe by injecting compressed air at the base. This system is widely used in aquaristics for water filtration, in petroleum engineering, and in dredging operations due to the absence of moving mechanical parts.
• Brass-plating — The act of brass-plating and its result; a technological process of coating the surface of a metallic object (usually made of steel, iron, or cast iron) with a thin, uniform, and adherent layer of brass. This treatment is carried out through electrolytic (electroplating) or thermal methods, aiming to protect the base material against corrosion and to give it a distinct aesthetic appearance similar to gold.
• Annulling — Causing, bringing about, or certifying the abolition, invalidation, or annulment of an act, effect, or phenomenon; (noun) a technical device or electronic component used to suppress, neutralize, or reduce to zero a signal, noise, or error within a system.
• Assembling — The act of assembling and its result; a technological operation, manual or automated, through which the component elements of a product, machinery, or structure are grouped, fitted, and joined according to a pre-established technical schematic. It represents the final phase of the industrial manufacturing process in which separate parts become a functional whole.
