DEVICE FOR IDENTIFYING PARTS IN ENCLOSED NONMETAL PACKINGS Russian patent published in 1995 - IPC

FIELD: automatic control. SUBSTANCE: parts contained in nonmetal packings during their manufacture, sorting-out, and storage are provided with identifying sensors made in the form of oscillating LC circuit whose tuning frequency determines unambiguously identifier of particular part or group of parts with one identifier placed in common packing, and decoding unit is built up of series-connected high-frequency oscillator, amplitude detector, and voltage drop signal shaper, high-frequency oscillator voltage changing unit, electronic switch unit, decoder, and display unit. EFFECT: reduced time and expenses associated with identification and check-up of parts placed in nonmetal packing. 3 cl, 7 dwg
