Title: Transmission systems
IPC: H04L29/06
Filed: 1973-01-23
Abstract: 1427622 Data transmission; error correction STANDARD TELEPHONES & CABLES Ltd 8 Jan 1974 [23 Jan 1973] 3482/73 Heading H4P In an electrical data transmission system in which each packet of a message is preceded by a plural bit label including information identifying the message and the packet, where packets of a message have to pass through one or more switching centres SC1, SC2, SC3, Fig. 1, so that they have to traverse two or more inter-centre links to reach the message's destination, error detection and correction (EDC) facilities are provided separately for each of the links, and in which for the data as transmitted via the links the sizes of the error detection and connection (EDC) blocks need not be the same on all of the links, so that dependent on the relative sizes of the packets and the EDC blocks a packet is conveyed over a link as one or more EDC blocks, and so that the EDC facilities do not affect the message structure. Fig. 2 shows the sending end EDC equipment. Normally gate G101 is closed. The EDC transmit terminal contains a counter recording the number of consecutive unsuccessful retransmission cycles performed. When this counter reaches a predetermined total, the terminal signals a prolonged fault by way of EDC control to a switching centre processor. At the same time it halts the retransmission data stored at a point when the next block to emerge is the earliest chronologically held in the store. When the switching centre processor is ready to transmit over an alternative route such as from a communications processor at switching centre SC1, Fig. 1 to SC2 via SC3 rather than directly to SC2 by the faulty link the processor signals the EDC control unit. This causes gates G101, G102 and G103 to open through which the data digits held in the retransmission store, the reading of the transmit side block sequence counter and the reading of the receiver side sequence counter are supplied to the processor. Assuming the retransmission cycle is of three blocks and that each block contains "h" information digits, the sequence numbering is in a cycle of 4. If now the EDC terminal of a link signals a prolonged fault to the switching centre processor and the next block desired by the receive side of the EDC terminal would have been sequence number 2 then over another route the processor receives a special packet header announcing a continuation of the interrupted traffic and that data starts with the digits originally sent over the faulty link in a block with sequence number "4". Under these conditions the EDC transmit terminal at the remote end of the faulty link was performing a retransmission cycle with blocks numbered 4, 1, 2 (in that order) and blocks 4 and 1 were correctly received before the fault, but the acknowledgements of these blocks were corrupted in transmission. To avoid duplication of data blocks the first 2h data blocks correctly received after the special header, over the alternative route must be discarded. If the fault is corrected then can switch back to original link for remainder of message.

Title: Photoelectric microscope display
Inventor: KOULICOVITCH MAURICE
IPC: G01B11/00
Filed: 1970-01-26
Abstract: 1275546 Photo-electric microscope SOC GENEVOISE D'INSTRUMENTS DE PHYSIQUE 26 Jan 1970 [28 Feb 1969; 10 Dec 1969] 3658/70 Heading G1A A photo-electric microscope which produces an output signal dependent on the displacement of a mark under investigation, from the optical axis of the microscope, and which operates by a back and forth scanning of the mark by the use of an oscillated optical member, is provided with circuitry to compensate for inaccuracies in the indication of the displacement introduced by the slowing-down of the scanning device at each extreme of its movement. In the arrangement of Fig. 2, an A.C. supply is provided to the microscope 1 to operate the oscillating scan. Each time the beam crosses the mark'under investigation a pulse is produced from a photo-cell in the microscope and these pulses are amplified at 2, 4 and shaped at 3 before application to a bi-stable circuit 5. The time relationship between the pulses of the pair of pulses produced in each scanning cycle is representative of the displacement of the mark from the optical axis. The first pulse changes the state of bi-stable 5 and the second resets it to produce the outputs I, II on the output lines of the bi-stable, the deviation from a true square wave increasing with the displacement. Instead of indicating the output of the bi-stable (after integration by a capacitor) directly, it is mixed with signals a, b obtained from the A.C. supply to the scanning device, phase shifted at 7 and rectified at 8, so as to compensate for the abovementioned inaccuracies, which are especially important when the displacement of the mark from the optical axis is large. The charging current for the capacitor is of the form S shown in Fig. 1 as opposed to a simple square wave. In the arrangement of Fig. 3 (not shown), the photo-cell output suitably shaped and the compensating waveform are mixed in the bi-stable circuit, the compensating waveform being obtained by rectifying the supply to the scanner, filtering through only double this frequency, phase shifting, and mixing with a D.C. voltage.

Abstract: 878,767. Ink-ribbon mechanisms. GROSS, H., and GROSS, S. Jan. 31, 1958 [Feb. 4, 1957], No. 3760/57.. Class 100(4) An ink-ribbon reversing mechanism comprises a pair of levers 33 bearing on the ribbon and when the change in diameter is such that e.g. the spool 11 is nearly full, the end 31a of the left-hand lever 33 engages the tail 38 of a latch 34 releasing a pin 28 mounted on a sliding rod 25 coupled to the right-hand spool mechanism. The rod 25 is normally in relaxed position between the tension of two opposed springs 30, Fig. 4, positioned between the arms 31 of the levers 33 and the pins 28, but as the left-hand lever 33 is moved counterclockwise, the left-hand spring 30 becomes increasingly compressed so that when the latch 34 is engaged, the rod 25 moves positively to the right. In so doing the pins 28 disconnect left-hand feeding and detent pawls 19, 40 and permit the right-hand pawls to engage their ratchet wheels 18. The pawls are rocked for ribbon feeding action by a machine connection at 21b, segments 21, and interconnecting link 22.

Abstract: 1,124,141. Counting-apparatus. PERKINELMER CORP. 27 Jan., 1966 [24 Feb., 1965], No. 3782/66. Heading G4D. In a system for counting objects of irregular outline, the field in which the objects are dispersed is scanned in a succession of horizontal bands and the signal derived from each is compared with that from the preceding band. The first object 123 is labelled 16 by initiate number counter 4 entering this number in write register 6 at the end of the train generated by the object. This number is then entered in train number memory 9a at a corresponding address. As shown in Fig. 11, two further parts of object 123 are detected in the next scan. Comparison of the signal in this scan with that of the previous scan by write and read registers 6, 7 and compare logic circuit 8 shows that the same object has been detected. In scan IV a new object is detected and labelled 17. The process continues with the labelling of objects 18-21. Then in scan IX it is seen that objects 19, 20 are identical and number 19 is transferred from read register 7 through write register 20 to be entered into object data memory 9b at an address appropriate to object 20, so signifying a junction. In scan X object 17 joins with composite-object 19, 20 and 17 is added to the addresses in 9b appropriate to 19 and 20. At the end of the frame the train number memory 9a is scanned in reverse. Any number whose address in 9b contains two or more numbers indicates a junction and is discounted. The other numbers advance object counter 10 to register the total number of objects.

Filed: 1974-01-28
Abstract: 1435272 High density carbon black DEUTSCHE GOLDUND SILBERSCHEIDEANSTALT 28 Jan 1974 [5 Feb 1973] 03841/74 Heading C1A A readily dispersible, non-dusting high density carbon black is made by subjecting a dry- or wet-beaded carbon black to the action of shearing forces in the substantial absence of compressive forces to thereby convert it into powder form. This may be achieved by passing the bead form carbon black through sharp edged perforations formed in a rotating cylinder under the action of centrifugal forces. The bead form carbon black is preferably introduced in the vicinity of the axis of rotation. Delivery and discharge of the carbon black may be assisted by an air stream generated by the blade like configuration of perforations flowing in the same direction as the centrifugal force. The sheared carbon black is preferably allowed to discharge into a high volume space in order to eliminate the influence of compressive forces.
