Patent GB-579510-A (GB)
Abstract: 579,510. Gun sights. NASH, A. G. FRAZER-. Feb. 18, 1938, No. 5155. [Class 92 (ii)] In sights for guns on aircraft, a range-finding sight is employed having its prism or like adjusting means connected with devices which correct the sight axis in relation to the gun axis to take account of (a) range and angle of sight of target; (b) " own " speed, and (c) " enemy " speed. The corrections for the factors (a)'and (b) are obtained by a combination of cam and link mechanism and the corrections in elevation and training for factor (c) are obtained by employing speed-sensitive devices which are influenced by the range-finder adjustment and which measure the speeds of elevation and training generated in following the target. As shown, the range-finder sight 1 is pivoted on a shaft 2 in arms. 3 on a mounting 4 rotatable in a yoke 5 which is elevated on an axis 6 with respect to a trainable ring carrying the gun. The gun and sight are moved in elevation and training by hydraulic motors controlled by a handle 7, Fig. 2. This handle carries a thumb wheel 8 connected by Bowden wire 10 with means 11 for adjusting the prism of the rangefinder and for imparting the range factor to the units of the correcting mechanism. This range adjustment is conveyed as axial movements to (1) the cam 12 which adjusts the prism 76 of the range-finder, (2) the cams 13, 14 set by rotation to the reading of an air-speed indicator, and (3) the forks 15, 16 which control the speedmeasuring devices. Corrections affected by variations in elevation of the gun are effected by a cam 17 and corrections affected by training movements of the gun are effected by a cam 18. During elevation the follower 62 rotates round the non-rotary cam 17 which is slidable on the axis 6 to suit training. The cam 18 which is rotated by gear 23, 19 to suit training is movable axially to suit elevation and has a follower 47. The levers 46, 61 carrying the followers 47, 62 have fulcrums 48, 59 adjusted by the cams 13, 14 and move the sight in azimuth and elevation by arms 54, 64 respectively. The cam 12 adjusts the prism 76 through linkage 69, 66, shaft 65, cam 74 and arm 75 as shown. The speed measuring devices comprise friction discs 39, 25 driven at the speeds of elevation and training and engaged by rollers 38, 26 moved by the forks 16, 15 to suit range. The discs convey rotation to electric generators 36, 29 the voltages from which are measured by instruments 35, 30 having pointers 34, 31 which form the sight cross wires, the intersection of which gives the required displacement of the sight line.

In use a plastics grid is placed in each recess to support the membrane and then a plurality of the frames are supported on horizontal bars which engage slots I and are clamped together between end plates with a membrane sealed over each recess. Gaskets 7 engaged in slots 14 formed in the peripheries of the plates form seals between adjacent frames. These gaskets may be additionally secured to the plates by plastics anchoring pins. A herringbone-shaped-packing 12 may be interposed between the membrane and the clamp and filter paper may be interposed between the membranes and the recesses. The clamp 20 may comprise two plates 8, 9 connected by bolt 11. Alternatively, the clamp may be formed as a single resilient member or a spring tensioned member (Figs. 8 to 10 not shown). The plates may be formed of plastics material and the clamps of plastics material or a non-oxidisable metal, e.g. stainless steel. Uses of such a frame are said to include ultrafiltration on the chemical, dyestuff and papermaking industries and in gas permeation.

Abstract: 1313192 Rail vehicle undercarriages HONEYWELL GmbH 9 Dec 1970 [9 Dec 1969] 58348/70 Heading B7L [Also in Division G3] In a vehicle having a body 1 which may be tilted by means of jacks 3, an acceleration sensor 7 carried by the body 1 provides a signal indicative of transverse force on the body, the signal being taken via a low-pass filter 8 to a control device 9 and used to actuate the jacks so as to tilt the body in such a direction that the gravitational force opposes the transverse accelerational force. The cut-off frequency of the filter 8 is preferably 2 c/s. to avoid operation on transient forces. Logic and differentiating circuits 10, 11 provide a rapid reduction in the angle of tilt in response to a corresponding sensor signal. The control action may be further modified by the use of a rate-of-turn gyro 12 which senses the body's angular velocity.

The carrier i, Fig. 7, may be formed in the upstanding inverted U-section part of a lever g pivoted at h to the arm f, one leg of the U being slit at k, k and bent at one side to contact the other leg of the U and at the other side to leave a space l to receive an upstanding finger m on the arm f adapted to hold the flint in its carrier i The bar d carrying the friction surface e may have a bent up end d<1> so arranged with respect to the lever g and the pivot h that when the lighter comes into the inoperative position, the lever g contacts the end d<1> and then turns in a clockwise direction about its pivot h to ensure that the finger m is disengaged from the carrier i and that the flint will be free to fall vertically into contact with the friction surface e. When next the lighter is operated by pressure on the end of the lever g, the flint will be clamped in its new position by the finger m and consequently the flint will keep the projection p spaced from the platform o, but when the pressure is released the projection p will ride back along the platform o to relieve the wear on the flint, the lighter returning to inoperative position where the flint may adjust itself to a new position in contact with the friction surface e. The end of the platform o may have a raised portion g, Fig. 5, formed by bending a portion of the bar d upwardly, or by securing a piece of metal to the platform o, so that the projection p raises the flint carrier away from the friction surface when it approaches the inoperative position.
