Title: Improvements in or relating to gyroscopes
IPC: G01C19/38
Filed: 1923-02-09
Abstract: 193,397. Ansch³tz & Co. Feb. 17, 1922, [Convention date]. Gyroscopic apparatus.-The gyroscopic system of a compass, artificial horizon &c. is enclosed in an hermetically sealed vessel which floats freely in a liquid and is held in normal position by externally-acting forces. Fig. 1 shows a vertical section of a compass, the sensitive element being contained in a sphere 12 of insulating material which floats freely in the liquid-containing vessel 5 suspended in gimballs 3, 4. Mounted within the vessel 5 are electromagnets 6, 7 carrying conducting surfaces 14, 16 and an equatorial conducting ring 9, while the sphere 12 carries a corresponding ring 11 and surfaces 13, 15. Current is conveyed from a battery 8 to the ring 9, thence through the liquid 10 to the ring 11 and gyroscope motor 26. From this motor the circuit is branched, one part of the current passing through the surface 13, liquid 10. surface 14 and magnet 6, and the other part passing through the surface 15, liquid 10, surface 16, and magnet 7. With this arrangement if the sphere rises in the liquid the resistance in the circuit of the magnet 6 is diminished so that the sphere is pulled downwards and is thus held central. The apparatus may be operated by alternating current, the sphere being of conducting material and being centralized by the forces resulting from the creation of eddy currents. To avoid disturbance of the gyroscopic system by the fields set up by the alternating current the electromagnets may in this case be in the form of ring shaped coils with vertical axes. To diminish the, loss of energy in stray currents through the liquid the vessel 5 may be provided with inwardly-extending non- conducting screens. Fig. 5 illustrates, in horizontal section, means for causing the vessel 5 to operate as a follow-up element for the compass. The sphere 12 carries a half ring 11 and the. vessel 5 carries two conducting surfaces 9<a>, 9<b> both connected to the same pole of the battery 8. When the parts are in the positions shown the currents in the two circuits are equal but when relative motion in azimuth occurs between the vessels the currents become unequal. A differential relay &c. is included in the circuit to control a followup motor acting on the vessel 5. With this arrangement the compass card, and if desired, an auxiliary card as described in Specification 19224/10, may be carried by the vessel 5, the sphere 10 being totally enclosed and hidden. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the gimbal rings may be carried by the follow-up system so that the axes of suspension remain in fixed directions in azimuth. This subject-matter does not appear in the Specification as accepted.

IPC: B60D1/04
Filed: 1958-02-06
Abstract: 893,927. Fifth wheel couplings. TASKERS OF ANDOVER (1932) Ltd. Dec. 8, 1958 [Feb. 6, 1958], No. 3945/58. Class 103(5). A fifth wheel coupling of the type wherein rollers on a trailer run up ramps 6 on a tractor, comprises on each side of the tractor a roller engaging member 10 pivoted at 9 between a pair of upstanding fixed brackets such as 8, so that the member 10 may pivot from a roller receiving position, Fig. 4, to a roller 12 retaining position, Fig. 3. A latch member 16 pivoted at 17 to the brackets has teeth 14, 15 one of which may engage with a toe 13 on the member 10 to hold the member in a closed or roller engaging position. Members 19 on each side of the tractor are pivoted on pins 18 and are each provided with a finger 20 fitting into a recess 21 in the respective latch 16, and each member 10 is urged to an open or roller receiving position by a tension spring 27 and a link 26 pivoted to the member at 25. The members 19 are welded to a bar 22 extending across the tractor and provided with a centrally positioned downwardly extending lever 23 connected to a chain or cable 24 which may be pulled from the driver's position. In operation, when the rollers 12 run up the ramps 6 they engage and pivot the members 10 so that the toes 13 ride over the teeth 15 of the latches 16. The latches then snap over into holding position, and further forward movement of the rollers will only cause the members 10 to pivot further and engage the teeth 14. To release the trailer, the cable 24 is pulled to pivot the member 23 and the members 19 about the pins 18. The fingers 20 then turn the latches 16 about their pivots 17, which movement of the latches disengages the toes 13 of the roller engaging members 10 and allow these members to be returned to the open position by their springs 27. The rollers 12 are thus released and may be run down the ramps. Stops 28, 29 limit the movement of the latches and the members 10 respectively, and rubber sandwich buffers 30 are provided for the rollers 12.

Abstract: 634,388. Removing foreign matter from webs of textile fibres. HURST, E. Feb. 14, 1947, Nos. 4275 and 4276. Convention dates, Feb. 15, 1946, and Feb. 28, 1946. [Classes .120 (i) and 120 (iii)] Foreign matter, such as burr or seed, is broken and removed from textile fibres by drawing a web of fibres in a series of drawing rollers to position the foreign bodies in parallelism with the fibres, after which the foreign bodies are divided transversely into relatively shorter lengths and the shorter lengths are then split lengthwise. Preferred apparatus consists of three pairs of drawing rollers 2 4, 6 succeeded by two pairs of comminuting rollers 10, 14, the first rollers of which are grooved longitudinally and the second circumferentially, to divide transversely and split the foreign bodies. A drawing action takes place between the first comminuting rollers 10 and the last drawing rollers 6 and between the pairs of comminuting rollers 10, 14. Spring pressure is applied to all the upper rollers. From the comminuting rollers 10, 14 the fibres are received by a screen 18 rotated about a hollow tube 20 provided with a slot 21, through which suction is applied to draw off some of the broken foreign matter. A similar screen 22 and tube 24 is arranged to operate upon the opposite side of the web of fibres. The screens and tubes 18, 20, 22, 24 are vibrated at a high frequency so that broken foreign matter will fall from the fibres into hoppers 34, 36. A liquid, preferably oil, is sprayed or otherwise supplied to the fibres from a member 32.

Title: Improvements in or relating to switching systems for controlling electric lamps and other current consuming devices
IPC: H05B39/06
Filed: 1935-02-11
Abstract: 444,045. Electric signalling and remote control systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SMART, N. C., c/o General Electric Co., Ltd., Stoke, Coventry. Feb. 11, 1935, No. 4288. [Class 40 (i)] The switching of current-consuming devices is controlled by two or more two-position relays which are operated in a predetermined sequence by impulses of alternate polarity transmitted over a pilot wire, the current being derived from the supply mains. A pulse of longer duration is used for synchronizing the relays by restoring them to a normal condition. As shown in the Figure when key D is moved to the left the polarized relay A is energized. The relays A and B are such that their armatures remain in the position to which they are set. Relay A connects up lamp E and connects the right-hand winding of relay B to the pilot wire P. If the switch D is now moved to the right current flows through rectifiers RB and RD so that relay B energizes to light lamp G and connect the right-hand coil of relay A to the pilot wire. When the switch D is next moved to the left the right-hand winding of relay A is effective to restore the armature so that lamp E goes out and the left-hand winding of relay B is connected to the pilot wire. Movement of key D to the right energizes this winding of B to restore the apparatus to the position shown. To restore the relays from any point in the cycle the key D is held in the right-hand position. The time relay T energises to short-out rectifier RC and restore relay A whilst rectifier RD is conductive so that, with relay A normal, the restoring winding of relay B is energized. Specifications 354,847 and 361,535 are referred to.

Title: Manufacture of cellulose ethers
IPC: C08B11/02
Filed: 1931-02-11
Abstract: In the production of cellulose ethers, alkylation is effected in the presence of a salt of carbonic acid whereby the presence of free mineral acid is avoided and also the end of the reaction can readily be ascertained by the presence of free carbonic acid.  The products are neutral and can be readily washed.  Carbonates such as that of sodium, potassium, calcium or barium may be added in solid condition; or soluble carbonates maybe added in solution or may be produced in the alkali cellulose by treatment with carbonic acid.  In an example, 100-200 parts of alkali cellulose is mixed with 1 part sodium carbonate and ethylated with an excess of ethyl chloride at 100-140 DEG  C.  After 1 hour samples of gas are withdrawn and passed through baryta water, and as soon as a considerable quantity of barium carbonate is precipitated, the excess ethyl chloride is distilled. The residue is disintegrated, washed and dried.
