Abstract: 1430059 Deflecting propulsion jets HAWKER SIDDELEY AVIATION Ltd 2 March 1973 [2 Dec 1971] 56070/71 Heading B7G [Also in Division F2] A V/STOL aircraft has as propulsion plant a by-pass jet engine installed in the fuselage, the efflux being emitted through pairs of dirigible nozzles that direct the gases rearward for propulsion in the normal flight mode while in the STOL mode they are employed at least in part to create a blown flap effect. As shown, an aircraft is provided with rear and forward pairs of dirigible nozzles 12, 15 located under the wing 13. For externally-blown flap (EBF) operation the nozzles are swivelled to the positions shown, with the forward nozzles 15 turned slightly upward, as indicated by the thrust line T F , and the rear nozzles 12 turned down to the extent necessary to keep the respective thrust line T R  substantially parallel to the deflected wing flaps 14. The effluxes from the forward nozzles 15 are directed at the gaps 16 between the noses of the flaps 14 and the main part of the wing 13, so that some of the efflux passes through these gaps and flows over the flap upper surfaces to give the required blown flap effect. Thus in the EBF mode, the weight W of the aircraft is counteracted by the wing lift L W , the vertical component of the thrust of the rear nozzle effluxes T R  and the blown flap lift L F . Pitch control is, in this particular embodiment, effected by means of a canard wing 17, preferably with blown flaps, with lift augmentation provided by a lift engine 18 forward of the main propulsion engine 11. With the canard wing 17, a tailplane is not necessary.

The focus modulator 8 comprises similar optical prisms 8a and 8b or "male and female" prisms 8c, and 8d, Fig. 2, vibrated in opposite directions perpendicular to the optical axis at half frame (or line) frequency. This will result in a variations of the optical path length giving alternate frames (or lines) of the television different degrees of focus and video signals having different high frequency contents. The scene viewed by the camera is displayed on monitor 7 and means 5, 6 and 9 are provided to select a part of said scene to be brought into focus and indicate said part on the monitor, as for example enclosed by a luminous rectangle. Gating signal generator 5 comprises means under the control of joy-stick 6 generating voltage S representative of the co-ordinates of the selected part and comparison means receiving and comparing said voltages and the corresponding scan signals and generating a gating signal when equality is detected. The gating signal is used to open gate 9 and pass the selected video signal to a high frequency filter 11. The output of the filter is detected at 11 to produce an alternating waveform at half frame (or line) frequency and having maximum and minimum valves representing by their absolute valves the degree of focussing in the alternate focus (or lines) and by their signs the respective direction of the out of focus. Said waveform is then synchronously demodulated in phase sensitive demodulator 12 and the output thereof used to readjust the focus by means of servo drive 4 and focusing means 3.

Title: Data recording arrangements

Filed: 1971-12-14
Abstract: 1369040 Digital data storage SANKYO SEIKI SEISAKUSHO KK 14 Dec 1971 [14 Dec 1970] 57902/71 Heading G4C Data entered from a keyboard is recorded on magnetic tape in the form of a signal containing a mixture of different frequencies. Control and data characters are entered from a keyboard 47 and are encoded by a diode matrix to b.c.d. plus a parity bit. Each five bit item from the decoder is stored in a shift register 47 which can hold a block of 85 bit items. Depression of a keyboard key causes a shift pulse to be supplied from a one-shot multivibrator OSM 11. Data in the shift register is displayed on unit 48 which also indicates if the register contains a whole block of data. Each data item is passed by a NAND gate ND35-39 enabled by a synchronizing pulse so that the output of a respective oscillator f1, f2, f4, f8, f9 is shorted by a transistor 50 if the data item contains a zero in the corresponding b.c.d. or parity bit position. The remaining frequencies are combined and recorded on magnetic tape. Data in the registers is shifted by pulses from an oscillator 42 and counter 43 and when the registers contain a whole block NAND gate 34 detects the first word of the block to reset the one shot OSM11 to prevent entry of further data. The gate ND 34 also detects the absence of data in a block to automatically record space signals (11111) on to tape.  Instruction words for carriage return, line feed and tubulation are fed in binary form to the right hand stage of register 47 only when the registers do not contain data. Entry of data is then prevented by the resetting of OSM11 until the instruction is recorded on to the tape. An alarm signal is produced by circuit 44 if a block of more than 8 items is supplied from the keyboard or if data is supplied when the registers contain an instruction. The counter 42 produces 14 clock pulses but only pulses 6-13 produce the required 8 shift pulses while pulses 0-5 provide a period allowing the tape to achieve the required speed and to provide a space between blocks of data.

Abstract: 1382590 Record changer PIONEER ELECTRONIC CORP 30 Dec 1971 [30 Dec 1970] 60829/71 Heading G5R In a record changer using the turntable spindle described in Specification 1,377,378 in which the record release process is controlled by both longitudinal and rotational movement of a drive shaft in the spindle, a sensing lever is provided, actuated by the drive shaft, which maintains automatic operation of the changer until the last record has been played. The change process is controlled by cam wheel 19 driven by an auxiliary motor which with a turntable motor is initially energized on operation of a start button. The wheel 19 includes a cam groove 19a, including, shallow portions A, D and deep portions B, C, E, in which a cam follower 22 runs, a separation band 19b and a recess 19c in the wheel periphery above the band with which switch operating members 38a, 39a co-operate. On initial movement of the cam wheel from the position shown, member 38a moves out of the recess and actuates switches S1, S2 to maintain the auxiliary motor and turntable motor in operation and cam follower 22 moving into deep groove position B and C acts on control lever 21 which firstly allows the centre spindle drive shaft to be lowered so that secondary supports thereon engage all but the lowermost record, then secondly rotates it clockwise to withdraw the primary support and release the lowermost record and thirdly rotates it anticlockwise to open the primary supports to receive the remaining records. As the follower moves from part C to shallow part D of the groove the drive shaft is raised to disengage the secondary supports. Thereafter shafts 7, 8 drive slider plate 9 so that arm 10 frictionally coupled to the plate engages pin 4 on an arm 3 coupled to the tone arm and rotates the latter towards the turntable to a position over the start groove of the record defined by stopper plate 11 which is set by manual control 63 to the record size. Further rotation of plate 9 slides the arm lifter along inclined portion 9b of the plate whereby the arm is lowered to its play position. When recess 19c of the cam wheel is engaged by arm 39a the auxiliary motor is switched off by operation of switch S3. The auxiliary motor is restarted, e.g. by an end of record detector and when the cam follower reaches section E the control lever 21 again allows the centre spindle drive shaft to be lowered, which movement takes place if records are present on the spindle. The movement is detected by sensing arm 29 which acts on a further arm 30 to a route part 30a thereof below the separation band. Because of the absence of recess 19c below the band the part 30b of the arm prevents operation of switches S1, S2 by the arm 38 so that play continues. If the drive shaft does not move down due to the absence of records the part 30a is routed above the band and enters the recess 19c with the switch member 38a so that the switches are actuated and the record changer is switched off.

Abstract: 723,486. Automatic alignment control systems. VOILLAUME, E., THOMASSIN, Y. C. X. M. DE PRAT-, and BAGGIO, R. Oct. 8, 1952 [Oct. 10, 1951], No. 25259/52. Class 38 (4). [Also in Group XXXVIII] Apparatus for maintaining an object in a predetermined direction relative to the horizontal component of the earth's magnetic field comprises two thyratrons whose control grids are fed with the voltage induced in a solenoid rotating about a vertical axis, and therefore dependent in phase on the earth's field, and whose screen grids are fed with cyclically intermittent bias voltages of the same frequency whose phase depends on the direction of the object, whereby a variation in the direction of the object causes one of the thyratrons to fire, energizing a relay which closes a motor drive circuit to return the object to its required direction. As shown (Figs. 1, 2) the solenoid 1, carried on a shaft 2 driven by a motor 3, feeds thyratrons 16, 17 through an amplifier 15. The shaft 2 also carries a cam 8 co-operating with switches 6, 7 to produce the intermittent screen grid bias voltages, the switches being carried by a hollow rod 4 attached to the part 5 whose direction is being controlled, and capable of being rotated by a motor 9 upon energization of a winding 11 through relay 22 or 23, actuated by anode current of thyratron 16 or 17. The axis of rotation of the solenoid may be maintained vertical by a gyroscope or otherwise, or errors in the indicated direction of the controlled object produced by movement of the rotating axis outside the vertical N-S plane may be corrected by a system comprising a weight 50 suspended by a cardan joint from uprights 51 on a plate 52 which is rotatable together with the controlled part 5. The weight 50 is attached to the slider 53 of a potentiometer 54 in a bridge circuit whose unbalance current energizes a winding 61 to cause a motor 66 to rebalance the bridge by adjusting a further potentiometer arm attached to shaft 62, at the same time applying a correction to indicator dials via shaft 14.
