A head-up display apparatus for all weather runway landings presents to the pilot a visual representation in real world perspective of the horizon H-H, Fig. 3, and a marker N corresponding to a point E, Fig. 1, on a runway and also a visually projected line VMN intersecting the horizon H-H in a vanishing point V, which line is adapted to be rotated about this vanishing point V by means of a computer, the arrangement being such that the line VMN represents the real world perspective view of the centre line of the runway when the projected line coincides with the representation N of the point E on the runway and that the angle of the line is controlled by a computer which supplies signals to keep the line VMN in coincidence during flight with the point N after the line has been manually preset by the pilot. The vertical distance of the point M from the horizon line represents # the angle of attitude of the aeroplane and the horizontal distance from V to the centre line L-L of the display represents the angle α.

Abstract: 1,257,665. Weft patterning in shuttleless looms. ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI. 13 May, 1969 [30 May, 1968], No. 24301/69. Heading D1E. A weft is selected by energising the relevant magnet 37 to attract an armature 34 pivoted on a feeder 19. Bodily movement of a driver 5 from position I to position III then advances the feeder to present its weft 22 to a gripper 58 (which may operate as in Specification 1,103,241). As the feeder advances, an arm 27 pivoted on it moves away from a stop 24 and is then under the influence of a spring 31; if the weft 22 is broken, the spring swings the arm to open a switch 67 and thereby stop the loom. If the weft is intact, the arm 27 keeps the weft taut until the moment of picking. When a nose 29 encounters a stop 23, which swings the arm anti-clockwise to pay out the loop of weft between guides 48, 49, the weft being clamped at this stage between guides 46, 48 by energisation of a magnet 53 controlled by a switch 42 operated by a roller 40 on the driver 5. For the greater part of the pick, the eyelet 28 at the end of the arm 27 lies between the guides 48, 49 and the driver 5 remains in position III at which the switch 42 is open; weft can then run freely from the bobbin 45 through the brake 54, 55 which is loaded merely by a light spring 57. As the feeder 19 retracts at the end of the pick, the clamping magnet 53 is again energised and the arm 27 again comes under the influence of the spring 31, whereby the weft that has been inserted into the shred is pulled taut. If the weft has broken at this stage, the arm 27 has another opportunity of operating the stop motion switch 67. When the feeders 19 are fully retracted, the clamping magnets 53 are deenergised so that all unselected wefts are free to be withdrawn from their bobbins by the take-up of the fabric.

Abstract: 1,264,487. Lasers. COMMISSARIAT A L'ENERGIE ATOMIQUE. 8 May, 1969 [9 May, 1968; 14 Jan., 1969], No. 23517/69. Heading H1C. In order to produce laser pulses of short duration and/or a steep leading edge, an electrooptical shutter is placed in the path of a light pulse produced by a Q-switch laser, the shutter being opened when the laser pulse has reached its maximum intensity. In a first embodiment, Fig. 1, the light pulse from laser 1 Q-switched by KDP or ADP cell 5 is received a three-plate electro-optical cell 9 comprising two single crystals 10, 11 of KDP or ADP. A polarizer 16 whose plane of polarization is crossed with respect to that of a polarizer 6 receives the light transmitted by cell 9. In operation a voltage V is initially applied to electrodes 7, 8 of cell 5 so that the Q of the resonator 3, 4 is spoiled. At a given time a voltage pulse having an amplitude V and a sign opposite to the initial voltage is obtained by the discharge of capacitor 17 into coaxial line 15 through spark-gap 19 and applied to the electrodes 7, 8 to nullify the initial voltage. When the voltage across electrodes 7, 8 is zero the Q of the cavity 3, 4 is restored and a light pulse passes to cell 9 and polarizer 16 arranged so that when no voltage is applied to cell 9 the light pulse is suppressed by polarizer 16. After a given delay determined by the length of coaxial cable 15 the voltage pulse from capacitor 17 is applied to electrodes 12, 13, 14 of cell 9 to rotate the plane of polarization of the light pulse by #/2 and so result in it being allowed to pass through polarizer 16. The coaxial line 15 is terminated either by a matched load 21 or short-circuited depending on whether a pulse having a trailing edge is required or the width of the pulse. Instead of Q-switching laser 1 by an electro-optical cell 5 a rotating resonator prism may be used, Fig. 2 (not shown). In this arrangement part of the light pulse is deflected by a semi-reflecting mirror to cause the ignition of a spark-gap in series with a capacitor to discharge the latter through a coaxial line to the electrodes of electro-optical cell 9. More than one cell 9 can be used, the cells being assembled adjacent each other and the light passed therethrough via a prism and polarizer arrangement, Fig. 5 (not shown). Fig. 6 shows an arrangement where the laser pulse is generated by Q-switch laser 1 and an amplifying chain 37, 38, the laser rods of the latter increasing in diameter in a geometrical progression. The electro-optical shutter 9 is energized by a voltage pulse from the discharge of capacitor 25 through spark-gap 24 fired by the light pulse from laser 1. The arrangement attenuates super radiance in the chain and light reflected from a target placed at the chain is prevented from returning to the chain. The amplifying chain may be looped by prisms so that the distance travelled by the light can be matched to that of the electric pulse.
