#technical archaism

• Abiolan — An old commercial and industrial term used in the 20th century to denote a type of synthetic textile fiber or insulating material manufactured through chemical processes, characterized by high resistance to environmental factors and used in the production of technical yarns or fabrics.
• 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.
• Avtolet — An archaic or regional hybrid term, used ephemerally in the first half of the 20th century (influenced by Slavic/Russian terminology), to designate an airplane, aircraft, or self-propelled flying machine. It represents an early linguistic attempt to name aerial vehicles, combining the Greek element 'avto' (self) with the Slavic root 'let' (to fly), quickly eliminated by the French-derived neologism 'avion'.
