IPC: H04Q3/54
Filed: 1969-06-17
Abstract: 1,270,268. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. 17 June, 1969 [18 June, 1968], No. 30513/69. Heading H4K. A subscriber may arrange for calls to be diverted to a nominated other subscriber such diversion being effected by extending calls through free ones of a group of transfer switching circuits 12 each of which has two appearances A, B, on the line switching network. The extended path to the nominated other subscriber is charged, in automatic message accounting equipment AMA, to the subscriber who is called and responsible for nominating the diversion. A memory circuit 7 stores the directory numbers of nominated diversions in association with the identities of subscribers for whom call diversion is in force. The data in memory 7 is recorded by subscribers of requisite class-of-service who dial a service code and after a pause of ten seconds receive dial tone from the exchange register which has cleared the service code and stands by to relay the nominated directory number for diversion. Before recording the diversion number a connecton may be made to the corresponding station to check that the number recorded is the correct one. As calls may be diverted to an answering service capable of handling more than one call at a time, concurrent calls to the same subscriber are diverted over respective switching circuits 12. A subscriber with a call diversion in force is in no way inhibited from making calls and, if he dials his own number, he will be connected to the station nominated for diversion. A call is recognized as being possibly subject to diversion from an examination of the ringing code obtain in the translation of the wanted station number, part of the range of ringing codes being employed with a class-of-service connotation. If diversion is possible a search of memory 7 is made for the wanted station identity and, should it be found, a free transfer switching circuit 12 is seized its identity is placed in memory 7 for purposes of subsequent access and the A-appearance of the circuit 12 is connected to the calling line. Ringing is applied to circuit 12 but is tripped at once and is not made apparent to the caller. Detection of ringing causes circuit 12 to place a calling condition on its B-appearance the classof-service of which is such as results in a register seized for the origination using the circuit 12 identity to obtain the call diversion number from memory 7 and setting up the diversion by connecting the nominated station to appearance B of circuit 12. At this time also an announcement machine 16 is seized and is connected to the station away from which the call has been diverted. If the announcement machine meets a busy line or no reply it merely times itself out. The invention is described in the context of the American No. 5 cross-bar System described in United States Specification 2,585,904.

Abstract: 750,258. Mechanical relays. UNILEVER, Ltd. Oct. 26, 1954 [Nov. 10, 1953], No. 31112/53. Class 118(2) [Also in Group XXIV] Cam mechanism for mechanically reproducing a variable signal comprises a drum 1 on a power driven shaft 2 having a circumferential series of rods 4 slidable in grooves 3. For the major portion of the circumference of the drum the rods 4 are securely held against a x i a 1 movement by a belt 5 guided by pulleys 6, 7 and tensioned by a pulley 8 whilst for the rest of the circumference they are free to slide axially under the influence of an input signal shoe 11 and a spring-loaded aligning shoe 17. Thus as the drum 1 rotates the rods 4 are set in accordance with the variable input signal to act as a cam, when secured by the belt 5, to actuate a signal output shoe 14. This output shoe 14 will receive with a time lag and any desired power amplification a movement which is a mechanical reproduction of the input signal. The input and output signals may be in the form of angular movements of the shoes 11 and 14 or of linear movements of rods 13, 16 co-acting with the shoes 11, 14 respectively. Magnetic or electromagnetic means may be employed instead of the belt 5 for securing the rods 4. The device may also be used to register and store the variable input signal, such as the temperature of a batch process, over one revolution of the drum 1, which can then be continuously repeated by rendering the input signal shoe 11 and the aligning shoe 17 inoperative.
