Title: Improvements in or relating to pcm time-division multiplex telecommunications exchange systems
IPC: H04J3/00
Filed: 1970-08-27
Abstract: 1,270,196. Telephone exchange systems. SIEMENS A.G. 27 Aug., 1970 [28 Aug., 1969], No. 41277/70. Heading H4K. Connections over exchanges in tandem and linked by pcm, tdm channels are established at any particular exchange in the chain by detecting a channel calling on the receive highway of an incoming trunk and seizing on the send highway of the outgoing trunk that channel which is the first found free and is the least distant in time following the time slot of the calling channel, the exchange receiving over the calling channel the identity of the time slot to be used as the channel on the send highway of the incoming trunk to complete the four-wire path to the calling exchange, and the exchange selecting a time slot which is free and is spaced by the least distance in time before the time slot indicated by the calling exchange, the identity of such selected time slot being signalled forward so that the following exchange can seize it as the channel on the send highway of its incoming trunk this being the receive highway at the preceding exchange which is the particular exchange in question. Each exchange keeps a record of the channels employed for the backward path to the calling terminal and associates the record with the records existing in the service given to the forward path. In this manner clearing down of backward paths is effected without the need to signal channel identities between exchanges. At the calling terminal the send and receive channels may be chosen by the terminal to employ the same time slot to gain the advantage of synchronism.

Abstract: 1487750 Refreshing volatile memories SPERRY RAND CORP 30 Sept 1974 [1 Oct 1973] 42370/74 Heading G4C A volatile memory constructed on an LSI chip 10 and arranged to be continuously refreshed, comprises N recirculating shift register memory loops 0 to N - 1, data being clocked through the memory loops by two-phase clock signals # 1 , # 2  applied thereto at a frequency F D  from an external data clock signal source 20 via 2N gates 30-31; ...; 34-35, the memory loops being addressed by signals fed to the gates 30-31; ..., 34-35 on N lines 14-18 from an address decoder 12, N refresh clock signals of sequential phases and each of frequency F R = F D /N also being fed to the gates 30-31; ...; 34 -35 from a refresh clock signal source 24 via N lines 25-57, so that in operation each non- addressed memory loop is refreshed at the frequency F R  while concurrently a selected memory loop may be addressed. Data appearing at the outputs of memory loops 0 to N - 1 are recirculated to the corresponding inputs via N refresh circuits 15-19 and N lines 36-38. In use, if memory loop 0 is addressed via line 14, gates 30-31 are thereby enabled so that after 1 clock cylce the data in loop 0 is right-shifted 1 bit. In the next clock cycle, gates 32-33 are enabled by a refresh clock signal on line 26, gates 30-31 remaining enabled via line 14, so that after 2 clock cycles the respective right shifts in loops 0, 1 are 2, 1. The sequence continues until after N clock cycles loop 0 has returned to its original state and loops 1 to N - 1 are each right-shifted 1 bit. Data may be read out during the time loop 0 is addressed by a signal on a line 48 enabling a gate 50, a further gate 44 having been enabled by the address signal on line 14, the read-out data being present on a line 52. For writing, data is placed on line 52 and a write enable signal is supplied to a line WE. In a modification, Fig. 3 (not shown) the N memory loops 0 to N - 1 are divided into S subgroups where N=SÎ2<SP>n</SP>, and a separate refresh clock signal of frequency f R =F D /S is supplied in parallel to all the gates, e.g. (130)-(131); ...; (132)-(133) of a corresponding subgroup, e.g. subgroup 0, so that in operation, if loop 0 of subgroup 0 is addressed, it is refreshed at the frequency F D  whereas the other loops of subgroup 0 and all the loops of subgroups 1 to N - 1 are refreshed at the frequency f R . In Fig. 5 (not shown) each subgroup, e.g. 0, has only a single pair of gates, e.g. (200)-(201), the clock signals being fed in parallel to the memory loops of each subgroup, and a particular memory loop within a subgroup being selected by a loop address decoder (214).

Abstract: 982,484. Animal pens. R. A. BRADSHAW. Nov. 12, 1963 [Nov. 12, 1962], No. 42596/62. Heading A1M. A moving fold structure mounted on wheels 14 or other supports has one or more sections 20 in its front wall 10 which are displaceable outwardly by livestock contained within the structure and eating the growing crop immediate in advance of the structure, means being provided whereby the displacement is communicated to a haulage mechanism to move the structure slowly over the ground. Each section 20 carries a pawl 25 co-operating with a ratchet wheel 29 to wind a cable 32 on to a drum carried by the shaft 15 on which the sections 20 are hinged, the other end of the cable being anchored to the ground ahead of the structure. The sections 20 have a locking bar 35 pivotally mounted at 36 and connected by link 37 with a bar 38 carried by suspension rods 38<SP>a</SP> on the outside of the fold. An animal lying down displaces bar 38 to draw the bar rearwardly to engage stops 39 against cross-bars 20<SP>a</SP> on the sections thereby preventing displacement of the sections. A cultivating implement e.g. a rake or seed-sower may be attached behind the fold. In a modification the displacement of the movable sections operates an electric motor or other powered drive mechanism to wind up the cable and hence move the fold. The fold may be mounted on floats so that water channels may be used.

Filed: 1970-09-07
Abstract: 1280919 Supply systems for discharge lamps HONEYWELL Inc 7 Sept 1970 [9 Sept 1969] 42757/70 Heading H2H A supply system for the recognition lamps of an aircraft comprises a timing unit 10 for supplying a train of spaced bursts of A.C. power derived from an A.C. source 17 and two groups of lamp control units 11-13, 14-16, each group having a unit which responds to the beginning of the burst of A.C. power by flashing its lamp and a unit which responds to the end of the burst of A.C. power by flashing its lamp. The timer includes a pulse generator 36 and a logic circuit which controls the firing of a pair of back-to-back S.C.R.'s in an electronic switch 70. The switch 70 releases bursts of power from the 400 Hz source 17 to each of the identical control units 11-16. Each control unit has a trigger unit 114 provided with a manually settable switch 120, the two positions of which determine whether the associated discharge lamp such as 80 is flashed at the beginning or end of each burst. On receiving a burst of power, a voltage quadrupler 72 charges capacitors 78, 79, 101 and a capacitor (165), Fig. 3 (not shown), in the trigger circuit 114. At the end of the burst, the rapid discharge of the capcitor (165) allows the voltage across the capacitor 78 to be applied to the trigger electrode of an S.C.R 111 thus causing the capacitor 101 to discharge and the gas in the lamp 80 to be ionized by the voltage applied to its electrode 83. The capacitors 78, 79 discharge through the lamp which therefore flashes. The switches 120 in the units 13, 16 are in the opposite position to those in the units 11, 12, 14, 15 and when the units 13, 16 receive the first burst, capacitors 78, 79, 101 do not charge sufficiently quickly to enable the firing of the S.C.R. 111. The negative charge on the capacitor (165) which controls the trigger electrode of the S.C.R. 111 also prevents the S.C.R. firing at the end of the burst. However, on receiving the next burst, the positive charge on a capacitor (144) in the unit 114 overcomes the negative charge on the capacitor (165) to fire the S.C.R. 111 thus discharging the capacitor 101 and causing the lamp to flash. Hence the lamps in the units 11, 12, 14, 15 flash simultaneously at the end of each burst which has a frequency of 1 Hz whilst the lamps in the units 13, 16 flash simultaneously at the beginning of each burst. The aeroplane therefore has a forward flashing rate of 120 per minute and a rearward flashing rate of 60 per minute.
