Abstract: 1468999 Data transmission; synchronizing of systems using cyclic codes SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 23 Dec 1974 [27 Dec 1973] 55653/74 Heading H4P An arrangement for correcting slip errors in a system employing cyclic redundancy i.e. polynomial error detection, has at a receiver a register SR of n+2S stages where n = block size and S = number of bits#slip error.  It has been found that a strong conrelation exists between order and direction of slip hence circuits RL2, RL3, detecting particular configurations of the polynomial remainder, control inputs c, b for shifting register content forwards/ backwards by up to S bits. In Fig. 1, S=1 hence register SR has n+2 stages receiving incoming bits, together with divider DV which calculates the remainder R(X) from the polynomial S(X). The remainder is examined by (a) network RL1 and if incoming bits are free from line and slip errors, gate N1 is enabled and the message passes to a utilizing device (not shown); (b) networks RL2, RL3 detecting single bit slip errors and giving outputs to shift register SR one bit left/right accordingly. If none of RL1-RL3 give outputs messages are passed out through gate N2. After shifting one place, after initiation by RL2, RL3, if coefficient remainder is 0, gate N1 is enabled as before. If it is not 0, unit UC reverses the shift and enables gate N2; UC is shown in greater detail in Fig. 2 (not shown). When n> 1 both RL2, RL3 must each have n decoding units and UC must have a counter to "memorize" number of left/right shifts so that any such shifts may be correctly reversed before passing the message out as described above.

Abstract: 1404768 Ramp generators BRITISH AIRCRAFT CORP Ltd 5 Dec 1972 [8 Dec 1971] 57074/71 Heading H3P [Also in Division G4] A synthesized stepped analogue waveform is smoothed by generating a substantially sawtooth waveform of the same frequency as and in phase with the stepped waveform and with each cycle having the same height and direction as the corresponding step, so that the tooth slope is positive for each upward step and negative for each downward step, and summing the two waveforms. The stepped waveform is generated from an 8 digit ordinater stored in memory 10 and clocked out in parallel in the desired sequence by clocked counter 12. The parallel data passes via registers 13 and 14 to digital to analogue converter 17 from which the stepped waveform emerges. Register 14 delays the output by one clock period and the signals from each side of it (representing successive ordinates are added at 15 after one has been inverted. The difference corresponds to a step height and is applied to DIA converter 18 which is also supplied with a ramp voltage at the clock frequency. The converter output is a sawtooth voltage of each peak having a height corresponding to the difference signal and of polarity corresponding to that of the digital signal. This sawtooth waveform is added to the step waveform in operational amplifier 20.

Abstract: 1362049 Digital data storage: skew correction INTERNATIONAL BUSINESS MACHINES CORP 15 Dec 1971 [28 Dec 1970] 58161/71 Heading G4C A multi track digital data storage system, e.g. magnetic disc, drum or tape or an optical arrangement, has a skew compensation arrangement. It is stated that both static and dynamic skew can be compensated for. A magnetic disc 10 has two tracks 14, two pairs of transducing heads 24, 26, 32, 34 to reduce access time, and a logical track 35, 36 comprising half an adjacent pair of tracks and being divided into a plurality of variable length records having gaps therebetween. Transducing of a record occurs simultaneously on both tracks of a pair. The selection of which pair of heads to use is accomplished by circuit 50 which recognizes the disc positions by observing index pins 58, 60. Skew can occur since data written by one pair of heads can be read by the other pair and vice versa. This is corrected by measuring the skew present when a given pair of heads is being used and then adding half the measured skew to an immediately following gap interval within the record being addressed by the same pair of heads. This changes the time of simultaneous transducing. Circuitry for effecting this under control of a microprocessor is described with reference to Fig. 2 (not shown). Bit ring cycles between the occurrence of an early and a late track are counted, the resulting count is divided by two, and the result is added to the gap. The data (Fig. 3, not shown). Each record comprises count and data fields separated by an intra record gap with the records themselves being separated by an inter record gap. In another embodiment skew compensation can be effected by subtracting half of the measured skew from the gap. Where there are more than two tracks the compensation may be different from half the measured skew.

Abstract: 1450545 Automatic circuit breakers; vacuum switches; electromagnetic switches SIEMENS AG 21 Dec 1973 [29 Dec 1972] 59484/73 Heading H1N An overcurrent protection arrangement for a circuit including two contact members in normally closed relationship within a vacuum vessel has an overcurrent responsive drive means in electrical series connection with the contact members to separate the members and releasable latching means to retain them apart. In Fig. 2 an actuating rod 7 for a movable contact member 5 is attached to a bellows 4 and passes through the end cap of an evacuated vessel 1 in known manner and has attached to it a bevelled member 8 which forces apart resilient tongues 9 on being actuably moved towards terminal 11 by the sudden contraction of a helically coiled drive means 10 under overcurrent conditions so that the contact member 5 is then latched open relative to a fixed contact member 3. For restoration of contact member 5 into engagement with contact member 3 by the action of atmospheric pressure on the bellows 4 (Fig. 1, not shown) the tongues 9 are opened out by any suitable means. In another embodiment (Fig. 4, not shown) the drive means (10) and releasable latch means (8, 9) are located within the vacuum vessel (1) and the tongues (9) have soft magnetic extensions (13) which can be opened out by electromagnetic means using a coil disposed about the outside of the vessel such as 18 in Fig. 5 which shows a modified embodiment cf Fig. 4 with the contacts open.

Abstract: 1460747 Electronic counters restoring after power failure WESTINGHOUSE ELECTRIC CORP 28 Dec 1973 [8 Jan 1973] 59996/73 Heading G4A [Also in Division H3] Each bi-stable stage of a counter (Figs. 1, 4, 5, not shown) includes an inductor L wound on a core whose magnetisation is dependent on the state of the stage prior to a power failure and which voices the reactance of the inductor L to charge a time constant of the stage and thus cause it to be reset to the same state on restoration of the power supply. The bi-stable stage is a master-slave bi-stable circuit using cross coupled NAND-gates 42, 44 and 34, 38. The inductor L is included in the feedback path of the master bi-stable. On restoration of supply the voltage across resistor R L  increases either more quickly or more slowly than that across a capacitor C depending on the remanent magnetism in the core and therefore the reactance of L and thus causes the stage to settle into its original state. The specification describes a three stage reversible BCD counter using the stages and intended to be used to provide driving pulses for a magnetic mechanism controlling the position of the rods in a nuclear reactor. The inputs of the counter have delay circuits to prevent multiple counts when the counter is supplied by relay contacts subject to bounce. The counter is prevented from counting down below zero, to prevent false readings. A circuit (Fig. 9) is provided to ensure that the supply voltage is restored to the counter substantially instantaneously after it has built up following a failure.
