Abstract: 1,251,900. Programmed control. MOTOROLA Inc. Feb. 12, 1969 [March 7, 1968 (2)], No. 7485/69. Heading G3N. A supervisory control system includes a process control station supplying analogue signals to a process controlling device over control links. A supervisory control system has a central digital control element having a programme for computing true-value signals, which are fed through a digital-to-analogue converter to a plurality of process control stations which are addressed through a station selection array. A process control station, as shown, has three control links. The first control link 20 receives the true-value signals from the digitalto-analogue converter on a line 13 through an input gate opened by signals from the station selection array on lines 19A. The gated true value signal is stored in a capacitor memory of an amplifier 25, the output of which is fed to a process controlling device 21. A condition indicating signal is fed back to the digital control element on a line 22. A second control link 23 assumes control on the event of the first control link malfunctioning, or, is switched in at the discretion of an operator. The second control link includes an analogue controller 50 the output of which, through a manual select 30 takes over control of the processing controlling device and is responsive to a set point analog memory amplifier 58 or a set point unit 65 as determined by an analogue select 55. The amplifier 58 stores the condition indicating signal on line 22 to ensure bumpless transfer, through an input gate 68, enabled by lines 19A, and switch 60 during control by the first link. During second link control the switch 60 is set to apply the time-shared analogue signal on line 13 to the amplifier. A third control link 24 comprises a manual controller 75 selected by a switch 80 and the amplifiers 25, 58 track the manual setting. The control links are automatically selected by the switch 80, being operated by a condition responsive means 100 which selects the second control link on the event of a short-circuit or overload.

Abstract: 1,257,584. Speech secrecy systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 11 May, 1970 [14 May, 1969 (2)], No. 22566/70. Heading H4R. In a secret transmission system an audio signal is scrambled by combining the signal with the output of an oscillator whose frequency is varied by the signal generated by a shift register, with a similar shift register and oscillator at the receiver to effect unscrambling. Synchronization between the two shift registers is effected by deriving an audio signal from the shift pulse generator of the shift register in the transmitter, transmitting this audio signal with the scrambled signal, and using the audio signal at the receiver to phase synchronize the shift pulse generator of the receiver. As described, a speech signal is inverted in a balanced modulator 11 fed with a carrier from oscillator 12 whose frequency is varied in a cyclic manner by the combined output of shift register 13, fed with shift pulses at 625 Hz generated by division of a 2À5 KHz master oscillator 15. The divided frequency of 625 Hz is also added to the scrambled audio in adder 32 to be selected by narrow band filter circuit 17 at the receiver and used to phase lock the oscillator 22, via phase comparator 25, so that shifting of the shift register 20 at the receiver is synchronized with that at the transmitter. In addition, in order to synchronize the two shift register cycles particular states of the shift register at the transmitter are detected by detectors 37 and 38 to operate a bi-stable circuit 36 during a synchronizing period defined by a monostable 40 triggered by a manuallyoperated key 41. During the period between the detected states when the bi-stable 36 is in a predetermined condition a pulse of 2À5 KHz from oscillator 15 is added to the scrambled audio signal. At the receiver the 2À5 KHz signal is filtered by filter 45, detected by integrator 48, operates a Schmitt trigger 54 and passes, via gate 55, to reset shift register 20 to the same condition as that corresponding to the generation of the synchronizing pulse in the transmitter, so that after termination of the pulse the two shift registers will be in step. The monostable trigger 40, in the transmitter controlling production of the shift register synchronizing pulses has a period of operation such that 3-5 pulses are generated on each operation of key 41, and a counter circuit 57 is arranged to open gate 56 so that only 3-5 pulses can be effective to reset the register after which the gate 56 is blocked until the end of transmission. If the transmission is to take place over a carrier link the 625 Hz signal is transmitted as the difference between two signals so that shifts in frequency of the transmitted signal can be eliminated.

Abstract: 1,258,465. Electric selective signalling. C. E. G. LUNDGREN, and I. J. A. LICHTNECKERT. 20 Aug., 1969 [22 Aug., 1968], No. 41491/69. Heading G4H.  A system for presenting questions or problems to and collecting expressions of opinion from anonymous individuals of a group, e.g. viewers of a television programme, comprises a supply centre for distributing current to each television receiver and means to allow each individual to express his opinion by varying or not varying the value of the current to the supply centre, the total variation being measured at the supply centre, the variation being preset by the individual and rendered effective by a signal transmitted from the centre. In the form of Fig. 1 the viewer closes switch 2 to indicate his opinion, bringing load 1 into circuit. Relay 3 is closed by a beam of light from the television screen which is transmitted to take a measurement of the combined load. The total number of voters is measured by first instructing all individuals to close their switches 2. The relays 3 are closed by transmitting a beam of light and the loads measured. The vote is taken by instructing those having a given opinion to close their switches, and again measuring the load. The vote can be restricted to particular categories of viewers by including in the apparatus permanent memory devices such as a code sheet 7, Fig. 2, having a pattern of holes. The apparatus is housed in a casing which can be secured to the television screen by suckers. The viewers are asked to insert their code sheets 7 and close their switches 2. A light beam from the screen is then passed through a hole 9 common to all sheets to connect switched loads to the supply centre so that the total audience can be measured at the centre. The light beam is now switched to an opaque area of the sheets 7 and the audience measured again. The difference indicates the number of viewers with sheets 7. Now the viewers are asked to vote by closing their switches 2 and the beam moved from hole to hole on the sheet, to measure the number of voters with a cerrain opinion in each of the specified categories. If it is required to limit the viewer to a single vote, there may be provided means for destroying the code sheet 7 by means of a signal from the television set. This is received in a photo-cell and the signal derived used to operate a claw member which cuts the sheet 7. A code card having magnetic spots may be used the spots being erased to destroy the card.

Abstract: 1322953 Grading timber COOK BOLINDERS Ltd 19 Oct 1970 49620/70 Headings G1N and G1S A timber grading machine includes two pairs of opposed conveyors 20, 23, 19, 22 with flat surfaces for feeding and damping timber therebetween, one of the surfaces of each pair being arranged in a common plane, there being a deflecting member 35 between the two pairs for deflecting the timber by a given amount and means 38 for sensing the force applied against the deflecting member by the timber as it passes through the machine. As described three driven chain track conveyors 18, 19, 20 move a piece of timber through the machine, and three further track conveyors 21, 22, 23, urged downwardly by air bags 30, 31, 32 maintain the timber in contact with the driven conveyors. Conveyors 21, 22, 23 are lightly driven merely to maintain their rotation in step with that of the driven conveyors 18, 19, 20. Rollers 35, 39 on levers 36, 40 pivoted at 37, 41 respectively for limited pivoting movement protrude into the path of the timber through the machine to deflect it by an amount determined by the setting of adjusting devices such as 34 for roller 35. Guides 43, 44 direct the deflected timber back between the succeeding pair of conveyors. Load cells 38, 42 give an indication of the force exerted by the timber on the rollers 35, 39 which may be read from a control box 46. So that the signals from the two load cells may be directly compared, that from cell 38 is passed downstream at the same rate as the timber, the signal being delayed by means of magnetic recording on a drum driven at a rate proportional to the conveyors. Zones on a piece of timber giving signals below a particular value may be marked.

Abstract: 1327196 Controlling reactors REYROLLE PARSONS Ltd 6 Jan 1971 [14 Oct 1969] 50463/69 Heading G6C A reactor safety device operates automatically in response to a relative displacement between the reactor pressure vessel and the superstructure above it from which the control rods are suspended, for releasing the control rods to allow them to fall under gravity into the reactor core in response to the occurrence of a relative displacement in excess of a predetermined amount. In the embodiment shown, a control rod 10 is releasably latched within the lower end of a support tube 11 by means of three latch members 13 whose heads are held against a chamfered abutment 14 inside the support tube 11 by means of a conical end 15 on a plunger rod 16. The latch members 13 have cross-bars 13A at thier lower end which are engaged in an annular recess 10A beneath abutment surfaces in the head of the control rod 10. The rod 16 is biased upwardly by means of a spring 21 which bears against an abutment portion 22 of the rod 16 and a ring 23 biased within the support tube 11. The upper end of the rod 16 is tapered at 16A and has a flat end face 24 on which the conical end 25A of a detent strut 25 abuts. The upper end of the strut 25 is attached by a chain (not shown) to a motor-driven winch on a concrete superstructure above the pressure vessel. The strut 25 has a part-spherical intermediate portion 26 which bears against an inwardly tapering end cap 27 screwed to the top of support tube 11 and thus forms a fulcrum about which the strut 25 may move. Upon the occurrence of a displacement of the superstructure relative to the pressure vessel, caused for example by an earthquake, an explosion in the vicinity of the reactor or a structural fault in some part of the reactor, a tilting of the strut 25 will occur about the fulcrum 26 causing its conical end 25A to move across the face 24 of the plunger rod 16. Should the tilting exceed a predetermined amount, e.g. 2 degrees, the end 25A will move beyond the edge of the face 24 and the rod 16 will be driven upwards by the spring 21 thus releasing the latch members 13 and allowing the control rod 10 to fall into the reactor core.
