Title: Improvements in and relating to sighting devices for use on aircraft
IPC: G01C21/20
Filed: 1918-03-13
Abstract: 177,549. Wimperis, H. E. March 13, 1918. Angle-measuring instruments. - Relates to bomb-dropping sights and navigation instruments for aircraft, of the type comprising members adjustable in accordance with the vector quantities of air-speed, wind-speed, and ground-speed, and consists in the combination therewith of a compass and other adjustable members to facilitate the determination of wind-speed and ground speed vector quantities, and for course-steering. The air-speed bar 2 is adjustable in the fore-andaft line of the aircraft, by a hand-wheel 4, relatively to the fixed member 1 in accordance with the known speed in air of the aircraft. The windspeed bar 5 is pivoted to a block 3 on the bar 2 and carries a slider 6 adjustable by a hand-wheel 7 along the graduated wind-speed bar. A drift or ground-speed bar 9 is pivoted by a sleeve 10 to a vertical bar 11 and is slidable through a pillar 8 on the air-speed slider 6. A compass 16 is mounted on the fixed member 1 and has a dial plate 14 on which is marked a wind arrow 15, the dial plate being geared to the wind-speed bar 5 so that the arrow 15 is maintained parallel to that bar. A graduated bearing-ring 13 is mounted above the dial plate, and a clamping device 17 is provided whereby the ring and plate may be clamped or freed for joint or independent movements. A pointer 18 is carried by the member 1 and a second pointer 19 is displaced by angular movements of the bar 9. The vertical bar 11 carries sight members 23 which are adjustable on the bar for the altitude of the machine. Bombdropping foresights 24 are provided on the stem 8. The ground-speed may be determined by means of fixed or adjustable beads 21, 22 on wires 20 carried bv the bar 9. An object on the ground is sighted through the backsight 23 and its time of passage between the beads 21. 22 is a measure of the ground speed. Various ways in which the instrument can be used for course-steering and for wind estimation are described.

IPC: E04C2/40
Filed: 1941-04-04
Abstract: 545,890. Heat insulation. NADIN, A. April 4, 1941, No. 4495. [Class 64 (ii)] A quilt-like covering for gas purifiers, tanks and the like consists of two sheets a, b of fireproof, waterproof or like material such as tarpaulin, roofing felt, or brattice cloth, which are double-folded at the edges and secured by rivets c. Insulating material such as glass, silk, cork, slag wool, or hair felt in rigid or non-rigid form, is inserted between the sheets which may also be riveted together at intermediate lines f to divide the sheets into panels which may be folded over one another for transit or storage. Before applying the rivets at some points, fabric or metal loops e are interposed in the folded material and the rivets passed through them also. The loops serve to connect the covering to an adjacent covering, or to the apparatus covered, by a rope or wire threaded through them.

Title: Improvements connected with weft-inserting mechanism of looms for weaving
IPC: D03D49/24
Filed: 1929-11-11
Abstract: 349,038. Shuttleless and like looms. HUTCHINSON, HOLLINGWORTH, & CO., Ltd., WOOD, A. E., and LOWE, W. V., Dobcross Loom Works, Dobcross, Yorkshire. Nov. 11, 1929, No. 4569/31. Divided on 344,879. [Class 142 (ii).] Weft-inserting needles construction and operation.-In looms for weaving tufted pile fabrics the weft is inserted by a needle 22 carried by a supporting block 80, which is mounted for horizontal movement in guides (not shown), and is connected by a link 82 to the upper end of an arm 83 pivotally mounted at its lower end on a stud 84. A block 85, slidable on the arm 83, is connected pivotally to the lower end of a pendulum lever 86 mounted to swing about a fixed pivot 87, and connected between its ends by means of a link 88 to a crank pin 89<1> disposed eccentrically on a plate 89 fixed to a bevel wheel 90, which receives its motion from the motor 10 through gears 11, 12, 16, 171, 91. The action of the crank, pendulum lever, and sliding block causes the needle to have the desired quick traverse during the centre part of its movement, with a gradual decrease in the rate of movement towards, and a dwell at each end. To avoid damage by contact with the selvage shuttle 33, the outer end of the needle 22, Fig. 2, is slidably supported in an opening in the needle box 80 and is hollowed out to receive a rod 92, which is slidable in a block 93 connected to the needle box by bolts 94. A pin 95 passing through the needle bears against the head 921 of the rod 92, and between the head 92<1> and the block 93 there is inserted a spring 96 which is of sufficient strength to resist the normal tension of the weft, but which, if the needle meets obstruction, will yield and permit the needle to slide outwardly whilst the needle box finishes its inward movement. A block 97 fast on the needle slides on one of the bolts 94 and prevents the needle from turning.

A doll of the " crying " and " wetting " type comprises a rotatable head and a liquid reservoir rotatable in the body of the doll, flexible tubing between the head and the reservoir causing the reservoir to rotate when the head is rotated. A dolls head 4 is rotatably retained in position by a neck flange 30 and has flexible tubes 34, 38 connecting mouth and eye apertures with nipples 58, 60 formed on the top of a reservoir 44 which is freely rotatable in a supporting member 64 secured in the neck of the doll. A " wetting " aperture 16 is formed in the body which is sealed at the leg and arm joints, each joint comprising a flanged end on the limb and a plug 20 which seals the open end of the limb. In using the doll, liquid is received through the mouth opening 32 and only after the reservoir is filled to a level above the top of an overflow tube 52 does liquid pass into the body and out of the aperture 16. To cause liquid to issue from the eye apertures, the mouth is plugged and the body compressed, liquid from the reservoir being forced up through pipes 62 and tubes 38. The legs and arms may be stuffed and the doll may be of moulded rubber or vinyl plastic. Reference has been directed by the Comptroller to Specification 644,965.

The signals from two channels modulate different transmitters using the same carrier frequency, one of which radiates an omnidirectional field, and the other of which feeds spaced aerials in anti-phase which produce a field containing adjacent regions of opposite phase. A receiver may be designed to receive one or other or both of the channels without mutual interference. The master oscillator 4, Fig. 1, drives two transmitters 5, 6, each having a modulator 7, 8 respectively. The transmitter 5 feeds a single vertical aerial 1 and the transmitter 6 a pair of vertical aerials 2, 3 in line with aerial 1 and each spaced a number of wavelengths, for example ten, from aerial 1. The aerials 2, 3 are energized at equal amplitudes and in opposite phase through non- radiating lines 11, 12 and phase and amplitude equalizing networks 13, 14 respectively. A receiver adapted to reproduce the signals from both channels, comprises two similar vertical spaced loop aerials 15, 16, Fig. 4, positioned on a line at right angles to the direction of the transmitter and so spaced as to pick up signals of opposite phase from the field due to aerials 2, 3 at the transmitter. The aerials 15, 16 feed cathode follower stages V1, V2, through non-radiating lines F2, Fl respectively, and the outputs of stages V1, V2 are combined in parallel in stages V3, V4 to feed receiver T1 and in push-pull in stages V5, V6 to feed receiver T2, so that receiver T1 is only responsive to the transmission from aerial 1 and receiver T2 to the transmission from aerials 2 and 3.
