Title: Improvements in and relating to distant-reading compasses
IPC: G01C19/36
Filed: 1932-04-28
Abstract: 404,994. Gyroscopic apparatus; magnetic compasses. BROWN, S. G., 64, North Gate, Regent's Park, London. April 28, 1932, No. 12234. [Classes 97 (ii) and 97 (iii).] A distant reading compass, combining the N- seeking property of a magnetic compass with the stability of a gyroscope, comprises a repeating instrument actuated by a gyroscope, which is caused to precess in azimuth by the torque provided by a disc mounted on the gyro wheel and arranged near two electromagnets alternatively excited in accordance with the relative movements of a magnetic compass card and the compass bowl. In the form shown, the gyro 1 is mounted by horizontally and vertically pivoted gimbal rings 2, 3, in a frame 4 extending from a rotatable horizontal table 5. Two electromagnets 10, 11, with or without a third central one, are fixed in the frame 4 and are adapted to co-operate with a curved disc 12 on the gyro spindle in the manner indicated in Specification 359,071 in order to precess the gyro in azimuth. The circuits for the electromagnets 10, 11 are alternatively closed by a contact 33 on the magnetic compass card 22 co-operating with contacts 24, 25 fixed to the rotatable compass bowl 18. The gyro 1 is caused to precess relatively to frame 4 in the same direction as the card 22 rotates relatively to the bowl 18. A contact 16 fixed to the gimbal 3 is adapted on precession of the gyro to contact with one or other of two conducting segments 13, 14, on the table 5 and energise one or other of electromagnets 43, 44. The latter rock a frame 39 carrying two friction wheels 34, 35 geared by pinions 36, 37 respectively to a spindle 26 adapted to rotate the table 5 and bowl 18 by worm gearing 27, 28 and to operate a repeater 31 by means of the cam contacts 30. One or other of the two wheels 34, 35 is drawn against the continuously driven wheel 33 by the electromagnets to cause the spindle 26 to rotate in such a direction that the frame 4 follows up the gyro 1 and the bowl 18 the card 22.

[Also in Divisions F1, F2 and G3] Fuel is injected into the jet pipe 61, or pipe leading from a compressor, of a gas turbine by a rotary sleeve 63 having internal splines 70-75 which define recesses a, b, c. Fuel is admitted to the recesses via a rotary pipe 67 and cylindrical part 69 of the sleeve and divides between the recesses in relative amounts proportional to the widths of the latter, and is discharged through radial ports in the sleeve. The port diameters are proportional to the widths of the recesses in which they are located. The streams issuing from the larger ports extend further into the gas stream, which feature is enhanced by providing external bosses on the sleeve. The recesses may have more than one port, the ports being spaced axially or circumferentially. The splines may be non-parallel and the fuel pipe may be axially adjustable. If the fuel pipe is stationary or rotated slowly, the splines may be extended up to baffle 66. The sleeve may diverge away from the fuel pipe.

Divided out of 486,770 under which a Specification was laid open to inspection under Sect. 91 of the Acts. June 7. 1937. [Class 38 (v)] A mercury switch has a conducting container 110 of square cross-section forming one electrode which is separated by a ceramic member 114 from a second electrode 122 having in contact with it a small body of mercury 133 in a pocket between members 122, 114. A main body of mercury 117 is adapted on tilting to merge with the mercury 133 and connect the two electrodes. A film of an insulating liquid 190, of an alkaline nature such as commercially pure triethanolamine covers the mercury and is stated to affect the mercury surface such that merging of the bodies is fast retarded and then takes place suddenly over a large area. The square section of the envelope and member 114 gives a long straight surface of merging. In a modification, the moving body of mercury makes contact directly with the second electrode, and the envelope is encased in moulded insulating material.

Title: A new or improved machine for twisting wire and the like for use as snares for rabbits and other animals and for other purposes
IPC: D07B3/12
Filed: 1919-05-27
Abstract: 142,322. Gillick, G. May 27, 1919. Traps for animals.-In forming snares for rabbits &c. and for other purposes, wires are twisted together by an apparatus comprising a rotatable non-slidable pin 13 and a slidable non-rotatable pin 18 carried by separate brackets 1 and 15, and a reel from which the wire is led over the pins. The wire is led the desired number of times round the pins, and the pin 13 is then rotated by a handle 12 through gears 10, 11 to twist the strands together and to form the loop through which the other end, when severed, is passed to form the running noose. When the loop is to contain an eyelet, this is put on the pin 13 and the wire led round it. The brackets are secured by screws 6 through pins or spikes 4, 8 to a bench 3. The pin 17 which may form part of or be secured to the pin 18 is provided with a notch 21 to receive a locking pin 22 and is retracted by a spring. The pin 22 prevents movement of the pin 18 when the wire is bent round the pins, but is removed when twisting begins so as to allow the pin 17 to be slidable. A construction of reel is described. Each snare when made is removed from the pins and the next then made, the snares being severed from each other when the reel is empty. The holes in the pegs for setting up the snares may be made by holding the peg against a drill, which replaces the pin 13.
