Patent GB-1052556-A (GB)
IPC: H04Q11/04
Abstract: 1,052,556. Automatic exchange systems; circuits employing bi-stable magnetic elements; semi-conductor switching circuits. WESTERN ELECTRIC CO. May 28, 1964 [June 4, 1963], No. 22047/64. Headings H3B, H3T and H4K. A telephone line circuit comprises a line having a subset, a magnetic core, D.C. supply means for switching the core from a first state to a second state in response to a call from said subset and means for applying ringing current to said line, said ringing current being inductively coupled to said core to switch it to said second state when said subset replies. The invention is described with reference to a time division system modified for party line working. While the line is idle pulses are applied to conductor 44-1 to connect the line circuit to the pulse highway 81 every 500 cycles. These pulses are shorted to earth through transistor 70. Conductor 24 is periodically earthed to maintain core 31 magnetized counter clockwise. Originating calls.-When either party goes off-hook contacts 7-1 and 7-2 are closed to complete the calling loop through core 31 whose magnetization is thus reversed. The magnetization periodically reverses with the pulses applied to 24, and the positive pulses picked up on 57 trigger a PNPN device 50 to cut off transistor 70. Current flows through a capacitor 64 to a negative source 62 until 50 cuts off. 64 discharges through resistors 63 and 65 to keep transistor 70 cut off during dialling intervals when pulses on 57 temporarily cease. The pulses on 44-1 now appear on 67-1 and are returned to control 43 to notify it of the service call. A time slot is allotted to the call and corresponding pulses are applied to 44-1 every cycle. Identifying calling party.-Positive pulses with a small A.C. ripple are applied to highway 81 in the call's time slot and smoothed by filter 41. The positive signal makes transistor 45 conduct, and the A.C. signal is rectified at 53 and makes transistor 47 conduct. Relays 20 and 40 are energized. Contact 7-3 is closed only when the tip party is off-hook in which case relay 30 is energized via conductor 86. Current then flows from 87 through the core 31 and the pulses on 44-1 are returned to control 43 via 67-1. If the ring party originates the call, pulses are not returned. Terminating calls.-Positive or negative ring- ing control pulses are applied to highway 81 according as the tip or ring parties are to be rung. Transistor 45 or 46 conducts to energize relay 20 or 30 respectively to connect ringing current from a source 21 to the tip or ring conductors. When the called party replies 7-1 and 7-2 close to connect ringing current, attenuated by the switchhook impedance 8, through the core 31. Pulses on 44-1 are returned to control 43 to indicate the reply. When the invention is used on a four party line, positive or negative ringing current may be connected to either tip or ring conductors.

Abstract: 1,238,172. Electrical measurements. NATIONAL RESEARCH DEVELOPMENT CORP. Nov.11, 1968 [Aug.11, 1967], No.37103/67. Heading G1U. In a measuring system in which output signals from an impedance network - e.g. unbalance signals from bridge 11 - are indicative of the variable being measured and are amplified by an amplifier of selectable gain, provision is made for sequence of reference output signals of predetermined magnitudes to be produced, e.g. for calibrating a pen recorder fed by the amplifer, a different sequence being produced for each value of amplifier gain. In the embodiment shown the bridge comprises four strain gauges 12-15. The reference output signals, representative of particular strains, are produced by altering the impedance ratio of a pair of supplementary bridge arms so as to unbalance the bridge. The supplementary arms comprises resistances 37, 38, initially made equal by zeroadjuster 26, so that provided transistors 43, 46, 49 are blocked the bridge is balanced in the absence of a strain to be measured. By unblocking any one of these transistors, however, one of three reference signals is produced at the bridge output, respectively corresponding to the unbalance caused by shunting resistance 38 by resistance 28 alone or in series with resistance 30 or 29. Switching circuits control the transistors 43, 46, 49 so that on momentary depression of switch 35 a sequence of all three, two or one of the reference signals is produced Fig.4 (not shown), depending on the position of switch 34, ganged to the amplifier gain (sensitivity) selector switch 36. In this way three, two or one reference levels are recorded by the pen recorder, the number of levels so recorded also serving to identify the sensitivity range in use. The reference signal sequences may alternatively differ in their order rather than in the number of signals they contain.

Abstract: 1,265,799. Battery charging systems. PARTRIDGE, WILSON & CO. Ltd. 13 Aug., 1969 [17 Aug., 1968], No. 39441/68. Heading H2H. Also in Division H1] In a battery charging system of the kind wherein a voltage-sensing means energizes a timer when the battery voltage reaches a predetermined value and the timer switches off the charging current after a predetermined run period, means are provided to re-activate the timer at the end of its run period if a settable switch is in a set position and to return the switch to its normal condition such that the charging is automatically terminated at the end of the second timer run period. Thus an extra " gassing " or " equalizing " charge may be provided automatically at weekends, for example, by throwing the settable switch on Friday evenings. In the embodiment described, A.C. mains are connected to terminals A and C and terminals B and C are connected to the input of a transformer-rectifier system (not shown) whose output is connected to terminals + and -. When a battery is connected across terminals + and - current flows through relay coil 2, contacts 2<SP>1</SP> are closed and thus coil 1 energized to close contacts 1<SP>1</SP> and energize the terminal B so that charging commences. When the battery voltage rises sufficiently the relay 3 closes contacts 3<SP>1</SP> to energize a synchronous motor 5 which drives timing mechanism (Figs. 2 and 3, not shown-see Division H1) via a clutch which is held engaged while coil 6 is energized. At the end of its predetermined run period the timer opens contacts 5<SP>1</SP>, coil 1 is de-energized, contacts 1<SP>1</SP> open and charging ceases. Contacts 5<SP>1</SP> are normally held open since clutch coil 6 is maintained energized until the battery is removed to allow contacts 2<SP>1</SP> to open, whereupon coil 6 is de-energized and a spring returns the freed timing mechanism to its start position wherein contacts 5<SP>1</SP> are closed in readiness for a subsequent charging cycle. If, however, switch 14 is set to close contacts 14<SP>1</SP>, 14<SP>111</SP> then coil 6 is de-energized as soon as contacts 5<SP>1</SP> (and hence 1<SP>1</SP>) are opened and the timing mechanism is restored at the end of its first run period, contacts 5<SP>1</SP> are closed and a second timed charge is given. Restoration of the timing mechanism also returns switch 14 to its normal position (shown) wherein contacts 14<SP>1</SP>, 14<SP>11</SP> are closed, so that at the end of the second timed charge the normal conditions prevail and charging terminates as before. The circuit including capacitor 37 and rectifiers 38 is to prevent contacts 2<SP>1</SP> being held closed by the pulsed D.C. if the battery is removed while charging is still proceeding; capacitor 37 passes the pulses which energize coil 4 and cause contacts 4<SP>1</SP> to short-circuit coil 2, ensuring release of contacts 2<SP>1</SP>. Alternatively the relay 4 could be arranged to respond to the higher opencircuit voltage. A zener diode and transistor switching device may be added to render relay 3 more sensitive.
