Title (EN) SYSTEM FOR THE REGISTRATION OF THE PASSAGE OF ARTICLES THROUGH A PREVIOUSLY DETERMINED FIELD
(FR) SYSTEME D"ENREGISTREMENT DU PASSAGE D"ARTICLES AU TRAVERS D"UN CHAMP DETERMINE A L"AVANCE
Abstract: front page image
(EN)In a system for the registration of the passage of articles through a previously determined field the transmitter (2) and the receiver (3, 4) are connected to a common aerial (1). A marker (18) on the articles receives and transmits electro-magnetic signals by the passage of a transmitter-and receiver bracket. In order to achieve the greatest possible security from incorrect registration the transmittance-and receiving function changes at a suitably high frequency, and an analytical circuit (7) monitors the number of received signals from the marker (18), and compares the frequency of these to that of the signals which are transmitted by the transmitter (2). The marker (18) consists of an inductive and a capacitive component, and the aerial (1) is shaped like a figure eight.
(FR)Dans un systeme d"enregistrement du passage d"articles au travers d"un champ determine a l"avance l"emetteur (2) et le recepteur (3, 4) sont connectes a une antenne commune (1). Un marqueur (18) sur les articles recoit et envoie des signaux electromagnetiques par le passage d"une applique emettrice et receptrice. De maniere a assurer la plus grande securite possible la fonction de transmission et de reception change a haute frequence, et un circuit analytique (7) controle le nombre de signaux recus du marqueur (18) et compare la frequence de ces signaux a celle des signaux qui sont envoyes par l"emetteur (2). Le marqueur (18) consiste en un composant a induction et a capacite, et l"antenne (1) possede une forme en 8.
