Title: Time division multiplex communication systems
IPC: H04J3/07
Filed: 1969-06-16
Abstract: 1310891 Multiplex signalling systems POST OFFICE 15 June 1970 [16 June 1969] 30400/69 Heading H4L In a time-division multiplex system in which a number (S) of asynchronous data channels are allocated time slots in sequence, a cycle of multiplexed signals consists of S frames, each frame comprising in addition to a number of message slots one stuffable slot, and a number of control slots (for indicating whether stuffing is effected in the frame), the cyclic allocation of channels to message and stuffing slots being advanced if necessary immediately prior to the stuffable slot so that successive frames in a cycle contain stuffable slots for each channel in sequence. The control slots may also be used for synchronizing the demultiplexer by inclusion of framing information in addition to the stuffing information, or a separate group of synchronizing slots may be provided in each frame. Logic circuitry for a suitable multiplexer and demultiplexer is described and illustrated.

Title: Measurement of blood pressure
IPC: A61B5/022
Filed: 1970-10-07
Abstract: 1311133 Sphygmomanometer WILKINSON SWORD Ltd 23 Sept 1971 [7 Oct 1970] 47740/70 Heading A5K Apparatus for automatically measuring systolic and diastolic blood pressure comprises a cuff, 6, 7 in fluid communication with a reservoir 10, a pressure leak 12 allowing the pressure of the reservoir and cuff to fall progressively, an element 38 which moves in a predetermined direction over a pressure chart in response to the drop in pressure, and a second pressure sensitive device which moves the element 38 transversely to the predetermined direction in response to systolic pressure pulses from the cuff. The pressure of the reservoir 10, initially above the patients systolic blood pressure acts through a duct 17 upon bellows 16 which act against a spring 32, and against an arm of an L-shaped lever 21 pivoted at its angle. At the distal end of the other arm 34, a pin 38, rigidly attached to the shaft 60 of a motor 36 is drawn down a pressure chart upon a platform 36. When the pressure of the cuff drops to the systolic pressure, a pulse is detected by a hot wire anenometer 52 which sends a pulse to the input of a servo amplifier 58 which simultaneously receives an input signal through lead 62 from the motor 36 whose magnitude depends upon the angular position of the shaft 60. The resulting output from the amplifier balances the signals by using a source of constant current to turn the shaft and thus deflect the pin 38, making a stroke on the chart, thus indicating the systolic pressure. The distal end of the arm 20 of the lever 21 is attached by means of a spring 25 and threaded screw 26 to a cogged wheel 29 by which the lever can be pivoted about its angle. The pen can by these means be set at zero pressure on the chart when the pressure of the reservoir and the bellows is atmospheric. The pressure leak consists of a sleeve 12 in the reservoir wall holes (72) and (74) Fig. 4, (not shown) communicating with the atmosphere and reservoir respectively. Hole (74) is offset from the axis of the sleeve, and a sphere (76) is forced against gravity, against the edge of hole (72), when the reservoir is pressurised by means of a pump 14. The cuff is formed in two parts 6 and 7, having bladders (80) and (82) respectively, Fig. 5, (not shown).

Title: Clock pulse generators
IPC: H03K3/282
Filed: 1970-10-22
Abstract: 1330639 Pulse generators BRITISH AIRCRAFT CORP Ltd 22 Oct 1970 [22 Oct 1969] 51797/69 Heading H3T In a fail safe clock pulse generator in which two trains of synchronized square-wave clock pulses are fed to a common clock output 8, the two trains of pulses are obtained from a pair of free running square-wave generators 1, 2 of the same nominal frequency having their outputs coupled together such that if either generator is running at a higher frequency than the other, the leading or trailing edges of the pulses from the generator having the higher frequency trigger the other generator from its first output level to its second output level or from its second output level to its first output level respectively. The outputs of the clock pulse generators 1 and 2 are coupled by resistors X, XI and if generator 1 is at the higher frequency then generator 2 is synchronized to the frequency of 1. Monostable circuits 4 and 5 are triggered by the leading and/  or trailing edges of the synchronized output pulses from generators 1 and 2. The outputs from the monostable circuits 4, 5 pass via isolating diodes 6, 7 to a common output clock pulse line 8. If one of the generators fails clock pulses are maintained by the other generator. The series pair of resistors X, XI forming the coupling is used for resistor types which short circuit in the case of failure. Alternatively a pair of resistors connected in parallel may be used where these resistors are of the type which form an open circuit on failure or four resistors consisting of two pairs of series connected resistors connected in parallel could be used for resistors which form either an open or short circuit on failure. The ratio of the resistors X and XI to the value Y must be such that the level of the pulse at A coupled from B is insufficient to trigger monostable 4. Similarly the ratio of X, XI to Y1 should be such that the level of the pulse at B coupled from A is insufficient to trigger the monostable 5.

Abstract: 1332788 Automatic test equipment HAWKER SIDDELEY DYNAMICS Ltd 31 Dec 1970 [31 Dec 1969] 63545/69 Heading G1U [Also in Division G4] In a computer-controlled automatic test equipment, signals from the computer 16, Fig.1, establish the inter-connections between, and the initial values set in, an array 18 of digital differential analyzer integrators 19, which then apply appropriate test signals to the unit under test UUT, 12, via digital-to-analogue converters 11, and the resulting output signals from the unit under test are returned to the computer via analogue-to-digital converters 20. The use of an array of digital differential integrators, with their own source of clock pulses 28, allows the computer to 'program' the set of test signals it requires, and leaves it free to process the resulting output signals from the unit under test. Each digital differential analyzer is represented by the symbol 19, Fig.3 (not shown) and each comprises two accumulating registers Y, R, Fig.2 (not shown), pulses dy being accumulated in the Y register, and the contents thereof being transferred to the R register upon the occurrence of a pulse dz to provide overflow pulses dx. Providing dx, dy and dz represent the frequencies of the pulse trains they denote, Y = #dy, and dx = Ydz. Interconnections are described Figs. 4 and 7, (not shown) showing how trigonometric functions can be generated, and how multiplication can be effected, see Division G4.
