Abstract

An electromagnetic pulse recorder comprising several armatures operable in chronological sequence and of which the last one actuated moves the next armature to be actuated in chronological sequence to an intermediate position between a common attraction pole and a retention pole, and games of contacts operable by the armatures and moved by them from a first control position to a second control position in response to the attraction of an armature and adapted to be replaced to the first control position in response to the attraction of the armature which it follows in the sequence the first mentioned armature, characterized in that the armatures (2) are arranged in a star shape around a core (9) arranged in a bowl-shaped stock or main pole bowl (26) and the sets of contacts (3, 4) associated with the armatures are arranged on the side of the core opposite the armatures and comb in a mount (15) fixed to the bowl of the main pole, said sets of contacts being actuated by cams (1) displaceable by the armatures, moving that cam that is actuated by an armature that is being attracted by the next cam be actuated to an intermediate position, so that the armature associated with this cam is moved by its mounting spring (12) from its rest position to an actuated position from which it can be attracted in response to the next impulse, each armature being retained in its rest position by the magnetic field that exists during an impulse and deviates from the retention pole formed by a secondary polar ring (11), the contact sets associated with the preceding armature being adapted, and which have been moved to its second control position by the previous impulse, to be replaced to its first contact position by the following impulse, while the associated contact set With armor attracted to an impulse they are adapted to move to their second control position in response to the next impulse.
