Abstract: 1,227,952. A.C./D.C. static converters. SYSTEM COMPUTERS Ltd. 17 April, 1968 [18 April, 1967], No. 17809/67. Heading H2F. [Also in Division G3] In an A.C./D.C. converter thyristors 21, 22, 23 (Fig. 1) are fired in proper sequence by drivers 18, 19, 20 on receipt of signals from coincidence gates 15, 16, 17. The gates receive inputs from phase sensitive devices 11, 12, 13 which are respectively connected to a reference 3-phase source (and which sense zero going positive instants) and from a ramp generator timer 14. When an output pulse leading edge from the timer coincides with an output signal from device 11 for example the coincident gate 15 only, produces a signal. The thyristors thereby receive pulses in sequence at 120 degrees displacement. The phase sensitive devices produce square waveforms which are also differentiated and used to reset the ramp generator timer 14. A signal applied at input A controls the rate of discharge of the ramp and when the ramp falls below a threshold level an output signal of square waveform is produced by the timer 14, the leading edge of which determines the firing point of a thyristor. The system may be applied to automatic control of field excitation of self excited alternators, the alternator output voltage being compared with a required value voltage in a comparator 26 (Fig. 2) to produce an error signal which is fed to input "A" of the thyristor control circuit to vary the conduction period of the thyristors and hence the field excitation. A signal may be applied at input B to displace the output signal produced by each phase sensitive device and hence displace the resetting of the timing device, resulting in an increase of the conduction angle of the thyristors.

[Also in Division G4] In a printing mechanism parallel-bit n bit signals from a store selectively de-energize n solenoids 49 (only one shown). Continuously rotating shaft 2 carries cam 104 which pivots lever 106 anticlockwise at a fixed point in each revolution, so lowering universal bar 108 and allowing the armatures 52 of the de-energized solenoids to move clockwise and pivot levers 54 anticlockwise. Subsequently, and under the control of further cams mounted on shaft 2, a mechanism, Fig. 4 (not shown), pulls bar 69 downwards so that universal bars 64, 66 move levers 54 selectively to left and right. Corresponding movement of sliders 57 rotates code bars 26 which select the character to be printed as in Specification 1,167,268. Operation of the mechanism, Fig. 4 (not shown), can take place only after the occurrence of a timing pulse generated when either of ferromagnetic elements 128, 129 passes a sensor 131. A control circuit (see Division G4) then releases a "start" solenoid (102) permitting engagement of the mechanism by the cams.

Abstract: 1,232,540. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd 11 July, 1969, No. 35065/69. Heading H4K. In a TDM exchange utilizing a four-wire switching network, each matrix of the network is reserved for transmission in one direction only and is physically separate from a matrix used for transmission in the other direction. The matrices may comprise integrated circuits or be carried on support cards carrying discrete components. Gates for controlling crosspoints are incorporated in the matrices. Fig. 1 depicts a single row (or column) of crosspoints in the form of a circuit module that is connectible with similar modules to form a coordinate matrix of any desired size. An input highway HW1 is correctly terminated by impedance R into four crosspoint transistors e.g. T1 that provide access to four output highways e.g. O1. Each crosspoint T1 has an associated transistor T2 which is turned-on with Ti by pulsing terminal X1 so as to provide a busy mark on the " Busy " lead. The controlling gates G1 &c. are opened by signals M from a circulating memory in conjunction with channel pulses T1, B8. The pulses BS4 open the crosspoint for one third of a time slot in order to pass signalling data while similar pulses operate transistor ST1 (by means not shown) in order to connect the highway to a supervisory apparatus. The pulses BS5 open the crosspoint for the remaining two thirds of a time slot in order to pass speech in PAM or PCM form. Signalling in respect of line loop, line disconnect and dialling may be effected using width modulation of the time slot pulses. Between time slots diode D is effective to discharge the highway so as to eliminate crosstalk. In order to construct a matrix, a plurality of such modules have their outputs 01 &c. multipled, and possibly the rows may be lengthened by connecting two or more modules together via the terminal X (Fig. 3, not shown). A network (Fig. 3) comprises three stages between a calling line and a junctor and two stages between the same junctor and the wanted line. The junctors (for each direction of transmission) demodulate and then remodulate at a different time slot in order to link the fixed time slots of each line. It is mentioned that the time slots may alternatively be allotted as required. The lines are arranged in groups each with its own time division system.

Abstract: 1,259,089. Cathode-ray tube circuits. NATIONAL CASH REGISTER CO. 24 March, 1970 [25 June, 1969], No. 14067/70. Heading H4T. [Also in Division G4] Code converter.-Characters in 6-bit code in the memory are displayed as a 5 x 7 dot matrix on a cathode-ray tube. A separate NAND gate and inverter (Fig. 13, not shown) are provided for each of 63 characters to provide a signal on 63 different lines respectively. (A 64th null character is not displayed.) The 63 lines each feed seven diode boards (Fig. 15), each having 5 outputs so that a unique 35-bit code is produced for each character. The board outputs are coupled to AND gates enabled by A and B counters (Fig. 4) so that the 35 bits appear in sequence (Figs. 17A, 17B, not shown). Display.-A digital recirculating memory can store 396 characters which are displayed in twelve rows on the cathode-ray tube. To allow time for the display beam to return to the following line 32 characters are displayed in each line and the 33rd character of each line is a null character. The display beam is arranged to step 32 places along each row and to step along a 10 x 6 matrix at each of the places. The beam is controlled by counters via D/A converters, an A counter controlling the steps to each row of the 10 Î 6 matrix, a B counter controlling a sawtooth waveform forming each of the rows, an E counter controlling the steps to the 12 rows of the display and a D counter feeding a gate arranged so that only 35 C5 pulses occur to control the steps along each row. The beam is normally blanked but is arranged to form a dot in the 7 Î 5 matrix whenever a " 1 " occurs in the 35 bit code. The beam is also arranged to produce a dot below each character position to indicate where each position occurs. D/A converters (Fig. 18A).-The outputs of the D counter are fed to terminals 127-132 connected to the base of transistors Q3 of a series of transistor triplets. Normally, transistor Q2 is conducting and holds lines 135a at a zero voltage level. If a " 1 " appears at any of the stages of the D counter, the appropriate transistors Q3, Q1 conduct and hold lines 135a at a positive voltage level. The resistor ladder 141- 146 is arranged so that as the D count is incremented the voltage on line 147 is increased in equal steps. The line 147 feeds a deflection power amplifier via a current sampling resistor providing feedback to the amplifier. Four D/A converters are provided and feed major horizontal and vertical deflection amplifiers to form the 32 positions in each of 12 lines and minor horizontal and vertical deflection amplifiers to form the 10 Î 6 matrices (Fig. 21, not shown). Memory details.-The memory is formed from 6 shift registers, each capable of shifting through 395 states. Each register is assembled from monolithic chips using MOS P-channel enhancement mode field effect transistors. The keyboard has a backspace key allowing data to be erased by decreasing the count in the Tx counter.

A lock barrel 27 is connected to a spindle 35 traversing the bolt, the end of the spindle having an element with a stepped cam surface which engages a cam follower portion 47 on the bolt whereby rotation of the spindle progressively withdraws the bolt, and switching operations are effected for accessories, for ignition and for a starter switch by a projection 49 which engages in a socket in a switch unit fitting in a chamber 13. With the key rotated to the "accessories" position the stepped cam element partially withdraws the bolt. Further rotation of the key to the "ignition on" position withdraws the bolt completely and removes a finger on a washer 42 slidable on the spindle from the path of a tooth 45 on an element 21 slidable in a recess in the bolt causing a spring to move the element to engage over a spline projecting from an inner surface of a side wall of the lock body thus holding the bolt withdrawn. The washer 42 is moved by a spring 43 beneath the tooth 45 on the element 21 and also holds the bolt withdrawn until the lock barrel has been moved bodily, which is possible when the key is rotated to "accessories" position in which position on obstructing peg 32 on the barrel aligns with an aperture in the lock housing. The bolt is also held withdrawn by an end surface of the cam follower exerting a wedging action on the stepped cam element on the spindle when the key is turned to the starting position and then released thus preventing reverse movement of the cam follower until reverse rotation of the key releases the wedging effect. In a modification the washer 42 is rotatable with the barrel, has the finger to restore the element 21 to the inactive position and is spring urged to engage in an opening in the bolt which is retained withdrawn until the barrel is moved bodily.
