Definitions

  • Certain marking systems compriseto this chest" at splitting: of the marking multiples; and each ofrthesex multiples is affected to a marking d'evice; either. permanently-"or temporarily through a finder; theroperations can therefore onlytake place: successively on these? splitted multiples.-
  • This invention enable'sv to:- utilize one marking:- mul ti ple only commonto all selectorsand markihg d'evices and nevertheless to detect and -render inoperative any entangling of: test and stopping circuits taking place," owing to severalsupply sources being' con nected" in series; during'th'esimultaneous op-- eration'of any registers i'nthe-process of marking It'achieves the independenceof the circuits 'oy i precluding the operation of a marking circuit when the: selectonmet 'is not that to which the register has beenconnected so asto -achieve-the communication: the-circuit entanglements have thus no longer any influence; since each 'ofthese 1 claim (01. 17918:)
  • Fig: 1 shows a known arrangement, to; which the inventionhas not'been applied, of acommon marking multiple utilised in the invention.
  • Fig. 2- shows a protective device according to the invention
  • Fig; 3 shows the arrangement of'Fi'g. 1, after it'has been provided'with the de'vice according to Fig; 2? g
  • Figs l'two selectors'only' S1 and S2 registers El" and E2" have been shown; the reg'isterE-l" is'connecte'ci tothe'selectorS-l in known manner through its chooser and the circuit of connection.- Noneofthe'se members has been represented? it is to operate;
  • the line-bundles are designated to the selectors by theregisters or" similar circuits owing" to the direction marking devices D l and'DZ', which are nu'merical' switches' locat'ed in the registers and whose homologous contact studs 383 and 403',
  • the selectors have no rest position and there fore start from any position at the moment of marking. If the wire ml were not multipled, the brush CSl could only stop on the contact stud hi3 through the following process: when the brush CSl reaches hi3 it energizes Al through the circuit: pole+ of Ul, Al, brush MII and con-* tact stud 385 of Dl, contact studbl3, brush CSI and pole of Ul; Al, being excited, opens, at MS, Rll of Sl, which stops; under similar conditions S2 would stop on b2l designated by the marking device D2.
  • each register comprises the following elements:' connected. in series, the brush of the marking device, a first relay, a contact of this relay, a contact of a second, two-winding relay, an electrically insulated battery and a connection between said battery and the brush of a selector; shunted on the exit of said first relay and the contact of said second relay a winding of said second relay; shunted on the contacts of said relays, a condenser and a resistance mounted in series; shunted on the entry of the first relay and the exit of the battery, a rectifier and the second winding of said second relay; theresistance oi the winding of said first relay and the resistance of the second winding of said second relay being higher than the resistance of the first winding of said second relay.
  • Fig. 2 The parts of the register which have just been enumerated are shown in Fig. 2, in which they are designated as follows:
  • U electrically insulated battery
  • 1 condenser
  • 300 designates a contact stud of the marking device, S the selector, CS the selector brush, b2li a selector contact stud, a2 a second contact of relay A and C the connection relay.
  • Fig. 2 corresponds to the normal operation, that is, without entangling, of a register.
  • the current flows through the circuit: pole+ of U, bl, al, A, brush 4B4] of D, contact stud 309, marking wire m, contact stud b2! and brush CS of the selector S, pole of U.
  • Relay A is energized and stops at al the rotation of the selector as has been mentioned; it causes the short-circuit of the upper winding of B to be cut at'al and operates C at a2.
  • Relay B can not attract its armature completely because its energizing circuit, which is connected in series with relay A, is opened at bl; B therefore vibrates, and its vibration frequency is chosen sufflciently high that A may be kept energized owing to the charging current of the condenser placed at the terminals of the contact bl.
  • Fig. 3 corresponds in Fig. 3 the following elements re spectively: M2 and a22, all and a2l, M1 and M1, ml and r2, yl and g2, RI and R2.
  • Fig. 3 as in Fig. 1 Al and A2 are operated in series through the following circuit: pole+ of Ul, bl'l, al2, Al, brush 4M of Dl, wire ml, contact stud b23, brush CS2 of S2, pole of U2, pole+ of'U2, 2221, 1122, A2, brush 402 of D2, wire m2, contact stud bl l, brush CSl of Sl, poleof Ul.
  • the lower winding of BI has a resistance sufficiently high to present the energization of B2 in series therewith through its upper winding and to bring about the release of A2; on the other hand Al, opened at on, is released; Cl and C2,
  • an automatic-switching, distant-communication exchange several registers each of which contains at least one marking device, several selectors each of which has a driving magnet, a marking wire multiplied on the homologous contact studs of the marking devices of the registers and on the homologous contact studs of the selectors, and, in each register, the following parts: connected in series, the brush of the marking device, a first extremity of a winding of a first re lay, said winding, the second extremity of said winding, a rest contact of this relay, an armature of a second, two-winding relay, the rest contact of said armature, a first pole of an electrically insulated battery, said battery, the second pole of said battery and the brush of a selector; shunted on the second extremity of the winding of said first relay and said armature, a winding of said second relay; shunted on said armature and the rest contact of said armature, a condenser and a resistance mounted in series,
