Title (EN) KEY,METHOD OF PRODUCING SAME AND PROCESS AND APPARATUS FOR USE IN THE METHOD FOR MAGNETISING THE KEY
(FR) CLE, SA METHODE DE PRODUCTION, ET PROCEDE ET APPAREIL UTILISES DANS LA METHODE D"AIMANTATION DE LA CLE
Abstract:
(EN) After assembly of a key, magnetic poles are imprinted on a magnetisable body (1) of the key by passing an electric current through a pair of parallel electrical conductors (22) which are spaced apart in a direction transverse to their lengths, have between them a magnetic conductor (26) and further magnetic conductors (25, 27) at the sides of the electrical conductors remote from the central magnetic conductor. Apparatus for carrying out the method comprises two magnetising heads, each having this arrangement of conductors and being angularly adjustable relative to each other and relative to the body to be magnetised about an axis of that body. The magnetising heads are also adjustable together along the axis of the magnetisable body.
(FR) Apres assemblage de la cle, des poles magnetiques sont empreints sur un corps aimantable (1) de la cle en faisant passer un courant electrique au travers d"une paire de conducteurs electriques paralleles (22) qui sont espaces l"un de l"autre dans le sens contraire de leur longueur, ayant entre eux un conducteur magnetique (26) et d"autres conducteurs magnetiques (25, 27) sur les cotes des conducteurs electriques et eloignes du conducteur magnetique central. L"appareil pour mettre en oeuvre la methode comprend deux tetes magnetiques, ayant chacune cette disposition de conducteurs et etant ajustables angulairement l"une par rapport a l"autre et par rapport au corps a aimanter, selon un axe de ce corps. Les tetes d"aimantation sont egalement ajustables ensemble le long de l"axe du corps aimantable.
