Abstract: 1,175,824. Stacking laundry articles. H. J. WEIR. 6 Sept., 1967 [6 Sept., 1966], No. 39868/66. Heading B8C. Apparatus for stacking folded laundry articles includes an inclined platform 3 on to which the folded articles are deposited and a stop 4 retaining them in position until the platform withdraws, allowing them to fall on to the stack 7 below. The preferred operating means is a pneumatic ram 5 which has a valve arrangement 6, 11 whereby the side of the piston which is switched to exhaust when the table is withdrawn, is connected to atmosphere before the retraction commences, thus speeding up this movement. The exhaust line is closed just prior to the end of the stroke to provide buffer and return means from the entrapped air. A normally closed switch 13 is opened by the platform to provide the necessary movement of the solenoid operated valve 6. Articles are fed in from a folding machine (not shown) by a conveyer 1, the machine controlling the stacking. A counter initiates operation of a discharge pusher 7.

Abstract: 1,237,381. Optical ranging. UNITED AIRCRAFT CORP. 10 Sept., 1968 [29 Sept., 1967], No. 43051/68. Heading H4D. Specification describes a C.W. laser rangefinding system, wherein the laser beam 12 is scanned by means of position modulators 14 and 16 in a T.V. type raster, the line scan being vertical. Fig. 2(a) shows the variation of beam elevation with time. The scan signal generators 34 and 40 also control the scan of display tube 28, a variable delay 46 being disposed in the line scan feed, the spot on the tube face thus lagging behind the direction of the laser beam by a variable amount. On intercepting a distant target the laser beam is reflected thereby and the echo pulse is received at 22 and converted to a video signal, Fig. 2 (b), which is fed to brightness modulate the display tube 28. Assuming the elevation direction 56, Fig. 2 (a) of the target is in the centre of the laser line scan, the beam will be pointing at the target at the times indicated in solid circles. If the target range is R, the reflections of the beam will be received back after a time T=(2R/C). If the delay introduced by means 46 is zero, two responses will be produced on the display 28 vertical spaced above and below the correct response position. Fig. 2 (c) shows by the solid circles the vertical position of the display tube scan when the reflections are received. Relay means 46 is thus adjusted to give the delay # such that the vertical positioning of the display tube scan becomes as shown in Fig.2 (d) and the reflections are received at the times of equal vertical positions in the upwards and downward display tube scans. Means 50, determining the phase difference between the laser beam vertical scan signal and the adjusted display tube vertical scan signal, feeds range display 52.
