Abstract: 1,251,830. Programmed computer. TELEFONAKTIEBOLAGET L. M. ERICSSON. 19 Dec., 1968 [19 Dec., 1967], No. 60522/68. Heading G4A. The invention relates to a programmed computer. A computer for use in controlling a telephone exchange works on different priority levels, work in progress being interrupted to allow working at different priority levels commencing with the highest priority level. Occasionally a memory area storing data concerning for instance the condition of devices B must be increased as more devices are brought into use. This may involve transfer of the data to a new memory area the transfer taking place on the lowest priority level. Since the transfer can be interrupted it is possible that data that is in the process of being transferred is altered in the initial location and stored unaltered in the final location. The computer is programmed to overcome this. An instruction store IM holds an instruction at address A1 which causes a protection limit GS to store the initial and final addresses of the memory area FB to be transferred. The instruction in A2 causes GS to raise the priority level temporarily whenever an information item address is in the protected range. A3 starts the data transfer, program commencing: in address Ap and causes the instructions held in addresses Ap to Ap + 7 to be performed, the instruction in Ap + 2 as indicated by line 5 causing jump to Ar if the bit is the first of FB and to Ap + 3 otherwise. The bits of field FB are successively transferred to the field FB<SP>1</SP> in data memory DM. If an interrupt causing change of data in the field FB occurs GS causes change of priority level control by altering the contents of register ILR to put a bit in level P (the highest priority level). All other interrupts occur only on lower levels S, A, B or C, the latter being the transfer level. As shown in Fig. 4 the interrupt was on level B at time T1 and at instruction address H. Hq causes, via line 12 and GS, the highest priority level to be set and storage of information required to continue the instructions on level B in field FU. An instruction at address C is obtained and causes writing of the required data at the address in FB and at the corresponding address in FB<SP>1</SP>. Then the level is lowered and the level B interruption continued. To ensure that all data is transferred an auxiliary control field FQ is also provided. When devices included in a connecting link are periodically sampled information regarding the busy condition arises without knowledge of the new address so the field FQ is set up with positions corresponding to the number of transferred items which positions are all set to 1 at the beginning of the transfer and are set to 0 when the positions are free.. At the end of the transfer the field is examined. If any positions are not zero then the remaining positions are updated.

A copying machine, in which copies are made from a master document and from selected overlays in a web, is controlled by a circuit incorporating a matrix. Each row of the matrix corresponds to a particular overlay in the web and each column to the number of copies to be made from the document with the selected overlay. Connections between rows and columns are made with conductive pins and the rows are connected to input terminals through selector switches whereby, in a programme, particular overlays can be rejected. A signal representative of an overlay being selected is fed to one of the input terminals and the signal derived from a column controls the number of copies made. It is stated that the circuit can be adapted to respond to a plurality of different documents by applying voltages to the input terminals in dependence on the nature of the different documents.

Abstract: 1296199 Decoder KING & DONNE Ltd 21 May 1970 24670/70 Heading G4H A decoder for decoding signals consisting of trains of like digital pulses, the number thereof representing time intervals between like amplitudes of an analogue signal, comprises means for producing a second, rectangular waveform which changes level midway between the changes of level of the trains of digital signals, and means coupling the second signal to a function generator to produce a decoded output signal. The input is fed to a dual shift register 411 together with the outputs of a clock 402 whose frequency has been divided by 2. The elements 420 to 429 of the dual shift register record a "1" when the incoming signal is a "1", and the elements 430 to 439 of the dual shift register records a "1" when the incoming signal is a "0"; thus the two halves of the circuit function in a similar manner. When a 1 reaches unit 429 of shift register 411 it sets AND gate 449 via gate 406 and then causes gate 406 to close, via delay 513. This in turn causes all the AND gates 449, 448 &c. to open if shift register 411 has a 1 in the corresponding unit, and this causes the contents of shift register 411 to be transferred to shift register 408, and in turn to shift register 526. The parallel outputs of the shift register 526 feed a digital to analogue converter 500, which in turn feeds a voltage inverting unit 504 which converts low voltages to high voltages and vice versa. The voltage thus produced is fed to a modulating unit 502. The output of shift register 408 is fed out in serial form by means of clock pulses from clock 402. Since these clock pulses have twice the frequency of those driving shift register 411, the digitally encoded signal contained in the serial output of shift register 408 changes its amplitude, i.e. goes from "0" to a "1" or vice versa half way between amplitude changes of the incoming signal. The outputs of shift register 408 is also fed to modulating unit 502 whose output thus comprises pulses of variable duration and variable amplitude. The output of this unit is fed to integrator 509 to produce a triangular waveform with peaks of equal amplitude, which is fed to a function generator 511 which produces a variable sine wave output. The left- and right-hand sides of the circuit function in a similar manner and operate alternately. Shift register 524 causes a gate 508 to be closed whenever there is no input into the circuit. In an alternative embodiment the digital-toanalogue conversion is carried out by means of exclusive OR gates (527 to 535), Fig. 2 (not shown), whose inputs are fed from shift register 526, and whose outputs control a series of gates, which in turn control a number of weighted resistors. In yet another embodiment. Fig. 3, the dual shift register 411 feeds directly via an AND gate bank to a shift register 408, whose output is fed out serially at twice the speed at which the input signal is advanced down shift register 411. This output is fed out through an integrator 508 so that the output of the circuit is a triangular waveform.
