Definitions

  • the present invention relates to relays, such'as telegraph relays, having a winding that is traversed at one time by operating currents, and at another by normal currents of opposed direction to the operating currents.
  • An armature is provided between two buffers or contacts, and is attracted by theoperating current against the active contact and bythe normal current againstfthe passive Contact.
  • Fig. 1 shows a relay operating in accord, ance with the Baudot principle which is modified in accordance with the present invention.
  • Fig. 2 is a curve showing the operation of -a relay without an auxiliary winding.l
  • Fig. 3 is a curve showing the operation of a relay with an auxiliary winding yaccording .to my invention.
  • the relay is provided with the following usual elements: Two soft iron cores A B are energized by the main winding C C traversed in opposite directions by the normal and operating currents. An'opcrating cur rent causes, for example, a positive magnetization of the free end of core A, and a negative magnetization at the end B, and vice versa for a normal current.
  • An armature DD is provided and is, e. g., positively polarized by a permanent magnet not shown in the drawing.
  • the armature is pivoted on a shaft E and its movement is limited by the contacts G F. As above stated, an operating current attracts the armature against contact G.
  • the arrangement is completed by two sources S1' S2 from which line LL is supplied with current the direction of which dej.
  • This normal relay may be arranged in any suitable manner and carries an auxiliary winding HH which, depending on whether the contact G or F is engaged, is supplied with current fromsource Sl or S2.
  • the direction of this winding is such that the additional magnetization always tends to maintain the armature on the contact on which it is resting. Due to this arrangement, 'before an operating or normal current can move the armature, it must produce an attractive force that is slightly superior to the force of the additional magnetization. The latter is adjusted to a suitable of a resistance R.
  • the armature does not respond to disturbances such asv JJJ theamplitude of IWhich does not attain a value equal to the sum of the signaling current and the auxiliary current. This sum may almost be equal to double the signaling current.
  • a relay having an armature the combination of a single operating Winding, an auxiliary Winding adapted ⁇ to maintain the armature against the contact on which it rests and means for reversing the direction of.y current flow in thevauxiliary Winding upon reversal of the armature position.
  • a single main Winding for moving the armature, means for resisting the influence of the main Winding on the armature during the early part of a signal impulse, and means for eliminating the effect of said first-mentioned means as the armature moves from its initial position.
  • a relay having an armature, a single main winding for moving the armature, an auxiliary Winding for resisting the influence of the main Winding on the armature during the early part of a signal impulse, means for eliminating the ei'ect of said auxiliary Winding as the armature moves from its initial position, and means for regulating the current in the auxiliary Winding.
  • the auxiliary current has the following for graduating the current throughthe auxiliary Winding and means for reversing the direction of current flow in the auxiliary Winding upon reversal, of the armature position.
  • a neutral relay having an armature, fieldmagnets having single operating Windiing and an auxiliary Winding, said auxiliary Winding forming part of an unbroken coni ducting circuit when the armature rests on either contact, and means for reversing the direction of current flow in the auxiliary Winding upon reversal of the armature position.
  • a relay having an armature and field magnets, means for producing magnetization ofthe field magnets, additional means for producing a secondary magnetization of the field magnets, said secondary magnetif Zation operating at first to maintain the armature in its initial position upon reversal of the magnetization of the field magnets by said rst means, but ceasing during movement of the armature and again operating to attract the armature when it reaches final contacting position.
  • a relay having an armature, an operating Winding, an auxiliary Winding forming part of an unbroken conducting circuit in either of the contact positions of the armature, means to graduate the current -flovv in said auxiliary Winding, said graduating means consisting of a variable resistance interposed between the auxiliary field Winding and the armature, means for reversing the direction of current flowing in the auxiliary Winding upon the reversal of the armature position, and means for. maintaining the armature in its final contacting position.
  • a relay having an armature, field magnets having an operating Winding and an auxiliary Winding, said auxiliary Winding forming part of an unbroken conducting circuit in either of the contact positions of the armature, means for reversing the direction of current flowing in the auxiliary Winding upon the reversal of the armature position, and means for-maintaining the armature in its final contacting position.
  • a relay having an armature
  • operating currentsfor moving the armature Ifrom one contact to another a mainline having one conductor connected to the armature and another conductor ⁇ connected to both contacts, and an auxiliary Winding associated with said field magnets connected in parallel with said main line.
