ABSTRACT "Magnetising Apparatus for the Magnetisation of Keys and Rotors of Magnetic Safety Lock Systems" The invention relates to magnetising apparatus for the magnetisation with coded orientation of magnetic blades to be embedded into two sides of a magnetic key shank forming part of a magnetic safety lock system, wherein tapering flux-conducting soft iron shanks are coupled to the poles of an exciting magnet of the apparatus. Between the shanks is an air gap into which a feeding mechanism feeds the blades to be magnetised. The magnet is a permanent magnet made of intermetal- lic compounds of rare earth metals of shell 4f with transition metals of shell 3d by means of powder metallurgy or casting. The areas of the soft iron which are contiguous to the air gap are made of a material of high saturation value. the direction of the feed of magnetic blades is parallel with the direction of the magnetic field (dipole) of the poles of the flux-conducting soft iron The invention also includes apparatus for the total through-magnetisation of the rotor discs of the lock-inserts of magnetic safety locks. In this variant, there are two symmetric magnetic circuits, with permanent magnets made of intermetallic compounds as above, with pairs of soft irons and tapering shanks facing one another across an air gap and being of opposite polarity.
