Title: Key telephone systems
IPC: H04M9/00
Filed: 1971-12-17
Abstract: 1369460 Key telephone system WESTERN ELECTRIC CO Inc 17 Dec 1971 [21 Dec 1970] 58601/71 Heading H4K A key telephone system uses instruments provided with tone signalling push buttons and line pick-up keys which keys provide encoded identity signals to a shift register, means for digitally encoding the identity of an operated push button for entry into the shift register and means for reproducing an audible tone representative of the operated push button. As shown each instrument 1, 2 is connected to its own station module through a six conductor cable which includes a 2-conductor speech path and a 4- conductor data path. Each instrument has a normal push button " dial " and a plurality of line pick-up keys. The station module is connected through a connection frame 6 to a plurality of line modules 9, 10 and intercom modules 21, 22 selectable by operation of the line pick-up keys. Operation of a line key provides coded signals which are sent on channel 104S to the station module which makes the necessary connection to the frame 6. Returning data signals, e.g. signalling tones and currents, are sent on channel 104R to the instrument. Exchange line call.-Operation of the keys 1, 2 in the embodiment shown provides a direct exchange connection through the appropriate station and line modules. The number is then dialled using the push buttons in the normal way. Intercom call.-Key 1C controls the connection of the instrument to the intercom modules and thence to intercom switching network 13 and dial tone is sent to the calling instrument. The push buttons are operated to call the required subscriber but instead of multifrequency tones being sent an additional array of contacts L1-L4, H1-H3 provide unique patterns of energization in shift register 212 corresponding to the button pressed. Simultaneously the tones are heard in handset 202 so that the caller can tell that correct " dialling " is taking place. The stored signals are sent by data transmitter 208 through a further register in station module 4 across the frame 6 through intercom module 21 to register 13R which divides the incoming signal and causes link allotter 16 to make the necessary connection through intercom module 22 to the called instrument. A ringing signal is sent to the called instrument and is received in data receiver 207 to operate the tone ringer and appropriate visual indicator. The transmission across the frame 6 is made through bare collector NAND gates in a time divided manner under the control of clock 7 and thus only a single connector is needed.

Title: Control of Battery Charging
IPC: H02J7/00
Filed: 1967-12-28
Abstract: 1,163,377. Standby battery charging systems. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 28 Dec., 1967 [28 Dec., 1966], No. 58952/67. Heading H2H. A load 2 may be supplied from a source 4 or, in an emergency, a battery 1, the battery being chargeable from the source 4, at a high rate when the battery is in a low state of charge and a low rate when the battery is fully charged, the transition from the high to the low rate being effected by a coulometer 11. The coulometer 11 comprises a tube containing two columns of mercury 12 separated by a quantity of electrolyte 18 which is translucent to allow light from a lamp 16 to impinge on a photo-resistor 15 when the electrolyte 13 is in the requisite place in the tube. During charging, the battery current flows through a resistor 3, the developed voltage across which is fed to the control windings of a transductor 7. An element 5 produces a stabilized D.C. voltage by means of Zener diodes, which voltage is fed to a converter 6 wherein the voltage is converted to a high-frequency alternating voltage which is applied to the A.C. windings of the transductor 7. The output of the transductor 7 is therefore dependent on the battery charging current as is the output of a rectifier 8 to which the transductor output is applied. The output of the rectifier 8 is used to control a selector unit 10 which not only controls the direction of current flow through the coulometer 11 but also establishes a shunt path (not shown in Fig. 2) around the coulometer 11 so that the magnitude of the charging current can be varied in dependence upon the battery temperature. As the electrolyte 13 moves along the tube during charging of the battery, its position will indicate the state of charge thereof and when the electrolyte is interposed between the lamp 16 and photo-resistor 15 the device 14 triggers the source 4 into its low output state whereby reducing the battery charging rate. The output of the converter 9 is also applied to a unit 9 which is connected to the rectifier 8 in such a manner as to ensure that the rectifier 8 has no output when no current is flowing through the resistor 3. When the battery is discharging the selector 10 causes the current flowing in the coulometer 11 to pass in the direction opposite to that when charging. In this case the electrolyte 13 will move along the tube in the opposite direction and its position will provide an indication of the state of discharge of the battery. The units 5, 6, 9, 10 and 14 all comprise transistor switching circuitry.

Abstract: 1337969 Producing Jacquard control tapes SCI-TEX Ltd 15 Dec 1970 [15 Dec 1969] 59601/70 Headings DIC and DIE [Also in Division G3] A translator for converting a colour pattern design into digital signals for producing Jacquard cards or tapes for the control of a knitting or weaving machine comprises a sensor producing signals, each of which corresponds to a colour or colour component in a part of the design, and means for comparing the signals with a reference signal, which is intermediate to the levels of one of said signals when the colour to which it corresponds is respectively present and absent in the part of the design. A scanner 58 is driven by a lead screw 54 to traverse the pattern tape 11, and has two photoelectric cells with respective red and green light filters so that the apparatus can detect red, green, white, or black squares on the pattern tape 11. The presence or absence of the two colours is recorded in digital form in two corresponding shift registers (103, 111) Fig. 5 (not shown) and each time a square of the pattern tape row is scanned the result is added to the registers, which have a number of storage units equal to the number of squares in a pattern tape row. When a complete row has been scanned, the contents of the shift registers are fed through apparatus controlling a Jacquard control tape punch mechanism four times, each time being analysed for one of the four different colours, and the tape puncher punches a row of holes corresponding to one of the four colours on the pattern tape. The pattern tape is then advanced and the neat row scanned in the same manner.
