- Small mechanical component — An archaic technical term or regionalism previously used in Transylvanian villages to denote a small-sized component within a traditional hydraulic mechanism (such as a mill wheel, a fulling mill, or a whirlpool) or a piece from a manual weaving loom. In industrial archaeology and rural economic history analyses, the word documents the empirical engineering solutions invented by craftsmen to optimize motive force transmission or textile guiding.
- Fan heater — A technical industrial apparatus or complex mechanical device used for the rapid heating of large spaces, structurally equipped with a fan forcing air through an electric or hot water battery and expelling it as a directed thermal stream. As an adjective, it refers to gaseous thermal phenomena or systems based on heat transfer through air.
- Anemostat — A terminal device or component mounted at the end of a ventilation or air conditioning duct, structurally designed to distribute, direct, and regulate the airflow introduced into or extracted from a room. It functions by uniformly dispersing the air current to prevent draft formation and ensure optimal thermal comfort without noise.
- Water meter — A precision measuring instrument mounted on a supply pipe, used for automatically recording and accurately determining the volume of water consumed within a specific time interval; a water meter. This mechanical or digital device is essential in municipal distribution networks for monitoring consumption and accurate utility billing.
