Title: Process for the dephenolation of phenolic oils, and for the de-oiling of phenol oils containing neutral oil
IPC: C07C37/72
Filed: 1958-10-06
Abstract: <PICT:0898679/IV (b)/1> Phenols are extracted from neutral oils in a column I, and crude phenols are freed from neutral oils in column II, each column being maintained under superatmospheric pressure and being heated at the base, and both columns being supplied, via pipes 27 and 28, with alkali carbonate solution, the temperature and pressure conditions in the columns being chosen (e.g. 180 DEG C. and 10 atmospheres) so that the alkali carbonate dissociates into carbon dioxide and alkali hydroxide, and the neutral oils are vaporized. The distillate from column II is introduced through pipe 35 into the neutral oil which is being fed through pipe 3 into column I; p  and the solution of alkali phenolate withdrawn from the base of column I is treated with CO2, obtained from the head of the column, whereby the phenols are liberated, and these phenols are introduced through pipe 36 into the crude phenols being fed through pipe 6 into column II.  Vapours of dephenolated oil and steam are withdrawn from the head of column I through pipe 10. The lye withdrawn from the base of column II is treated with CO2, obtained from the head of the column, in order to liberate the purified phenols.  The alkali carbonate which is re-formed in vessels 22 and 23 is conveyed through pipes 24 and 25 to container 26, from which it is pumped back into the columns. Specification 815,754 is referred to.

Title: Improvements in and relating to gyroscopes
IPC: G01C19/38
Filed: 1927-11-25
Abstract: 306,603. Henderson, Sir J. B. Nov. 25, 1927. Gyroscopic apparatus.-In a gimbal-mounted gyroscope having three degrees of freedom, the outer trunnion axis of the gimbals is controlled so as always to be at right-angles to the rotor axis, so that couples about the rotor axis, due for example to variations in the speed of the rotor, may have no component about the outer trunnion axis. The invention is particularly applicable to air-driven gyroscopes used for steering torpedoes. The Figures show a torpedosteering gyroscope in which the inner trunnion axis is vertical, and provided with the means described in Specification 234,419 for obtaining " angle-fire." The rotor 1 is pivoted on an axis 2 in the inner ring 3 which is mounted on trunnions 4 in the outer ring 5. According to the invention the ring 5 is mounted on trunnions 6 in an additional ring 7 which is mounted on trunnions 8 in the frame 9. Compressed air is introduced through the lower trunnion 8 and passes through pipes 10 to the trunnions 6 and thence through pipes 11 to the trunnions 4, the lower trunnion 4 being provided with a nozzle 12 for maintaining the spin of the rotor. To the upper trunnion 4 and) to a bridge-piece 14 fixed to the ring 3 is fixed a Y-tube 15 terminating in nozzles 16 the axes of which pass through the intersection of the axes 4, 6. The, jets from the nozzles 16 pass through shoots 17 on the ring 7 and strike a vane 20 constituting the rim of a spider 21 fixed to the ring 7. When the axis 6 is not at right-angles to the axis 2 the reaction of the air-jets causes the ring 7 to turn about the axis 8, this turning continuing until the axes 2, 6 are at right-angles. The means for controliing the steering of the torpedo are carried by the ring 7. The invention is also applicable to a gyroscope in which the axis 4 is horizontal. In this case the ring 5 is mounted in vertical trunnions 6 in a fork 7 mounted on an horizontal bearing 8 in the frame 9 (see Fig. 4, not shown). In a modified arrangement, the gyroscope is enclosed and the controlling air-jets are derived from the excess pressure within the casing. In another form in which the rotor is not enclosed, the residual velocity of the air from the nozzle 12 after it has impinged on the rotor is utilized.

Title: Improvements relating to dating stamps
IPC: B41K1/42
Filed: 1931-11-17
Abstract: 381.383. Hand-stamps. McCHESNEY, P. J., 111, Shirehall Park, Hendon, and DENNIS, C. B., 12, Montrell Road, Streatham, both in London. Nov. 17, 1931, No. 31843. [Class 100 (ii).] In a dating-stamp of the kind comprising type-bands passing over rotatable drums and over a supporting-bar 10 and wherein the types are inked by a pad 6 carried by an oscillatory frame 5, the frame is actuated by rods 2 slidable in holes or slots in the stamp-frame, the outer ends 7 of the rods projecting beyond the type faces in the inoperative position of the stamp. The pad is either mounted directly on the frame or is carried by a separate member 13 pivoted at 14 to the frame and spring-pressed in the anticlockwise direction. The frame 5 is connected by a pin 3 or by links to the rods 2 which are pressed downwardly by spiral springs 8 or by leaf springs so that the ends 7 of the rods extend beyond the types. The rods 2 are therefore raised when the stamp is applied to the paper, and the pad 6 is raised and swings to the left out of the way. Lugs 16 on the member 13 engage the upper surface of the bar 10 to maintain the pad in contact with the types ; the pad may be moved into a vertical position for re-inking and is then held by engagement of the lugs with the lower surface of the bar. The frame 6 may have a flange along the near edge to act as a guard preventing contact of the pad with the paper. The Provisional Specification describes a pin and slot connection as an alternative to the pivot 3.

Title: Improvements in and relating to a system for locating a receiving station with respect to a transmitting station
IPC: G01S11/04
Filed: 1946-10-28
Abstract: 636,185. Radio-navigation. SOC. INDUSTRIELLE DES PROCEDES LOTH. Oct. 28, 1946, No. 31919. Convention date, Sept. 1, 1942. [Class 40 (vii)] In a system for indicating the distance of a receiving system from a transmitting system, the transmitting system comprises two radiating elements, one located vertically above the other and the receiving system comprises means for measuring angles of elevation or depression of the two radiating elements. The system is described as applied to a radio system, but it is stated to be also applicable to systems using infra-red radiation. In an embodiment directed to the determination of distance between aircraft, one transmitting aerial is carried on the body of the aircraft and the other is supported beneath the aircraft on a length of cable which may be used for conveying electric power to a transmitter attached to its lower end or for conveying the radiofrequency signal to an aerial attached to the lower end. In the latter case the cable is shielded to prevent radiation from the cable itself. Alternatively, as shown in Fig. 1, the transmitter 4 supported by the cable 2, may be a self-contained unit powered by the airscrew 5. The cable itself may be used as an aerial for any further transmission it may be desired to radiate. The length ho may or may not be predetermined; if it is not predetermined, the aircraft transmits a signal indicating its value. The aircraft may also radiate a signal whose modulation indicates the heading of the craft. The receiver on another aircraft may comprise one or more loop aerials or an aerial mounted within a parabolic reflector. By measuring the elevation angles of the two transmitting aerials, and knowing the length ho, the horizontal distance between the aircraft may be determined. In an alternative system the transmitting system comprises two radiating elements mounted at different heights on a vertical tower. The tower may be mounted on an airfield to enable the pilot of an aircraft to determine his distance from the airfield or it may be mounted on a coastline for use by ships at sea. The. Specification as open to inspection under Sect. 91 describes means, for use in the embodiment wherein the distance between two aircraft is determined, involving mechanical display apparatus which positions a model aircraft relative to a reference point in accordance with the relative positions of the two aircraft. The receiving aerial comprises a universally mounted loop which it is stated can determine direction both in azimuth and in elevation. The loop is rotated to the correct azimuth setting and is then adjusted to obtain nulls on first the upper and then the lower transmitting aerial. The positions of the loop control, through a mechanical linkage, the position of a model aircraft which indicates the relative position of the aircraft whose transmission is being received. This subject-matter does not appear in the Specification as accepted.

Title: Vehicle hydraulic valve
Inventor: TREVASKIS HENRY WILLIAM
IPC: G05D9/04
Filed: 1956-10-26
Abstract: 868,825. Adjusting body height. DUNLOP RUBBER CO. Ltd. Oct. 21, 1957 [Oct. 26, 1956], No. 32654/56. Class 108(2). A' levelling valve for a vehicle fluid pressure suspension system operates as follows. When the vehicle is static with its body at the predetermined height all the ball valves except 69 are closed. Thus, liquid pressure in cham-: bers 3 of rear fluid springs 2 depresses a valve 25 in a: chamber 23 through pipes 10, 4, and passages 65; 61, 60, 57, 67 against a spring 29 to provide a circufation path for pressure fluid from a pump 13 through a pipe 14, passage 18, valve 25, passages 20, 19 and pipe 16 and back to a reservoir 15. When the load on the vehicle increases, springs '2 are compressed causing a rod 84, attached to the unsprung portion of the vehicle, to pivot a lever 85 clockwise to depress a ball valve 53 through a plunger 78 and block 90; depress a ball valve 73 through plunger 80, lever 93 and arm 91, and allow the ball valve 69 to be closed by a spring 70 by lifting plunger 81 through lever 93 and arm 91. Closing valve 69 cuts off pressure in chambers 3 from chamber 23, and opening valve 73 releases pressure in chamber 23 to outlet pipe 16 through passages 71, 48, 49, 19, and allows valve 25 to rise and close the connection between passages 18, 19. Liquid from the pump 13 now flows into chambers 51, 32. As valve 34 is closed, pressure in chamber 32 is ineffective. Valve 53 is open and liquid flows through passage 55, valve 58, chamber 56, passage 60, chamber 61, passage 65, port 6, pipes 4, 10 and into chambers 3 of springs 2 to force down pistons 8 and raise the vehicle body until the predetermined static distance is restored when all valves return to their original positions. If the load on the vehicle is decreased, the chassis will rise, and the lever 85 will pivot to move ball valve 63 off its seat through plunger 79, block 89 and cam 87. All the other valves are unaffected and pressure liquid from chambers 3 passes to the reservoir 15 through pipes 4, 6, chamber 61, valve 63, passages 66, 48, 49 and pipe 16, until the static height is regained when valve 63 closes. The levelling valve acts in a similar way when changes in load affect springs 2a except that the valves associated with springs 2a are opened and closed. Instead of the arrangement shown, one levelling valve could be connected between each of springs 2, and another between each of springs 2a, with a separate pump for each. Alternatively two of the springs could be controlled in parallel and the other two separately, again using two pumps. A practical arrangement of the diagrammatic valve mechanism described above is described and illustrated.

Title: Improvements in and relating to machines for opening and cleaning fibrous material
IPC: D01G9/00
Filed: 1920-11-23
Abstract: 180,351. Youlten, W. Nov. 23, 1920. Openers, cleaners, etc.; feeding openers &c.- A fibre opening and cleaning machine comprises an elliptical chamber 25, Figs. 1 and 9, surrounded by a rectangular casing 11. The material is fed into the chamber 25 through a duct 24, and is treated therein by one or more rotary beaters. The chamber is provided on one side with a grid 28 through which dirt escapes, and with a discharge valve 32. The beater comprises a cylinder 34 closed at each end by caps 36 secured to the shaft 21. The blades 35, Fig. 14 are twisted spirally and project from base portions 35<a> bolted to the cylinder, the nuts being locked by U-shaped strips 39. The blades are arranged in helices, starting from each end of the cylinder and meeting at the middle. The bolts securing the beater arms may be securcd by employing an inner concentric tube to engage the tops of the nuts. The dirt &c. passing through the grid falls into a hopper 17, Fig. 1 and is removed by a screw conveyer or by suction. The feed of the material down the duct 24 from a hopper 41 and the discharge of the material through the valve 32 may be controlled automatically by means comprising a pair of speed cones 44, 45. The device may be mounted on the top of the casing 11 as shown in Fig. 1, or suspended from the ceiling as shown in Fig. 3. The upper cone 44 is driven and drives the lower one through belts which can be traversed along the cones to vary the period of treatment by a screwed spindle 51 operated by a hand-chain 49 running over a pulley 50 on the spindle. The lower cone spindle 54 carries a worm 55 driving a worm-wheel 56 carrying on its upper surface cams 61, 62 which operate at the appropriate times poppets 67, 67a governing the movements of the discharge and inlet valves. The poppet 67a is attached to a rod 102 which, at the upper end is connected through levers 103, 106 to a shaft 107 carrying an arm 112. The movement of this arm operates through an adjustable link 113 the spindle on which is mounted the valve 42, which allows the material to fall from the hopper 41 down the duct 24 into the operating-chamber 25. The poppet 67 operates through levers 69, 72 a cross-head 66 sliding in a guide 65. This crosshead is attached to a rod 75 extending through the hollow spindle 57 of the worm wheel 56. The rod 75 is attached to an arm 79, Fig. 15, on a shaft 78 provided with cranked arms 82 attached by adjustable links 83 to the brackets carrying the discharge valve 32. This valve is pivoted on a spindle 77 carrying a sector 86 to which is attached a cord 88 passing over a pulley 93 and secured to weights 97. The shaft 78 has an arm 80 carrying a weight 81 so arranged that when the valve is open the arm 80 is vertical, whilst when the valve is closed the arm is horizontal and the weight exerts its greatest pressure. The weight 97 is adjusted to counterbalance the weight of the valve and to provide a slight excess to assist in commencing the closing movement.
