Title: An improved manufacture of aluminium soap lubricating greases
Filed: 1943-10-14
Abstract: In the manufacture of aluminium soap greases by the saponification of a saponifiable acid with aluminium hydroxide in the presence of an amount of lubricating oil at least equal to the weight of acid used, the aluminium hydroxide employed comprises a homogeneous material containing at least 75 per cent. of water in combined state and 4 to 8 per cent. of combined aluminium. Suitable known materials specified are termed gelatinous aluminium hydroxide, alumina hydrate pulp, alumina paste slurry, and gelatinous alumina.  Additional water may be mixed with any of these products.  The saponifiable acids specified comprise the usual fatty acids such as stearic acid, cottonseed oil acids, and hydrogenated fish oil acids, together with naphthenic acids and synthetic acids such as those made by the oxidation of paraffin wax.  The amount of lubricating oil present during the saponification is preferably 1 to 3 times the weight of the saponifiable material used.  The usual heating and stirring is employed to obtain a practically dehydrated product, the balance of the lubricating oil then being worked in.  The process may be either batch or continuous.  Other usual additives may be incorporated such as polyisobutylene of high molecular weight glycerine and oxidation inhibitors such as diisobutyl phenol.

Title: Improved manufacture of highly swellable inorganic substances
IPC: C04B41/50
Filed: 1935-06-12
Abstract: Bentonites or similar minerals which are only slightly swellable are treated to replace their exchangeable cations by monovalent cations such as Na, K, and Li, the product being freed from water and dried. It is highly swellable.  The quantity of exchangeable cation is determined and the mineral such as calcium bentonite treated with a compound of a monovalent base to replace sufficient Ca by monovalent ion.  The compounds may be added in solid or solution form.  Sodium, potassium or lithium salts which form sparingly soluble compounds with the exchangeable cations, for example carbonates, sulphates, phosphates or oxalates, may be employed.  Thus, 1000 kg. of Ca-bentonite, moist as mined, with 80 milli-equivalents of exchangeable calcium per 100 g. dry substance, is made into a slurry with water and mixed with 20--25 kg. anhydrous soda.  The slurry is agitated for 15 mins., de-watered, dried, and ground.  Bentonites, that is all clays containing the mineral montmorillonite, and bentonite-like minerals such as smectite, beidelite, ehrenbergite, damontherolite, fuller's earth and bole are suitable starting materials.  The addition of a few per cent of the products to non-plastic substances such as cori-moulding sand in foundry work gives an intimate binding or prevents settling of glazes, colours, enamels or the like in the ceramic industry.  One-fifth of the amount of clay usually employed suffices.ALSO:Slightly swellable bentonites and like earths are treated with compounds of monovalent bases to replace their exchangeable cations by monovalent cations such as Na, K, and Li.

Patent GB-169698-A (GB)
Abstract: 169,698. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Smith, A. B.). Oct. 1, 1920, [Convention date]. Automatic exchange systems. - A non- numerical switch E, of the type that remains, after the release of a connection, on the terminals of the trunk F last seized by it, is arranged to be non- selectable, even though idle, if the trunk F on which it stands is busy. The selectors which have access to the switches E, which may be selectors at another exchange, can therefore virtually hunt directly for an idle trunk F. In a group of switches E means are provided for ensuring that at least one of the switches has its wipers normally resting on an idle trunk. If a switch E is idle but standing on a busy trunk F, its test wire 25 is connected through the upper winding of a relay 30 and wiper 35 to the grounded test wire of the trunk F, and a selector testing the test wire 25 is not arrested. The testing current which flows through the upper winding of relay 30 is without effect on this relay, being opposed by current in the lower winding. If, however, the trunk F is idle, the selector is arrested, and in the usual manner momentarily grounds the wire 25, so that current flows through both windings of relay 30 in series. The relay 30, which now becomes energized, disconnects the stepping-magnet 31, switches the connection forward so as to energize the relays 44, 42, and connects the wire 25 direct to the wiper 35, which is grounded at the contact 43 of the relay 42. Each switch E controls a relay such as 33, which is energized if either the switch itself or the trunk on which it stands is busy, and when all the relays 33 of a group of switches are energized a circuit is completed for a master relay 32, which closes circuits to energize the stepping-magnets 31 of all the idle switches of the group until one of them reaches an idle trunk.

Title: Improvements in or relating to rotary engines, pumps and the like
IPC: F16K17/00
Filed: 1942-11-30
Abstract: 561,848. Rotary engines and pumps. KEELAVITE CO., Ltd., and JOHNSON, E. H. Nov. 30, 1942, No. 16970.. [Class 110 (ii)] In the rotary engine or pump described in Specification 551,991, the output is varied by the axial movement of one wall of the working chamber and means are provided for the escape of fluid from the enclosing casing when the pressure in the latter rises due to an outward movement of the chamber wall. The piston valve C, C<1> is now arranged to-provide also for the introduction of fluid when the chamber wall is moved inwards.- The end space B<1> communicates through an automatic valve with that one of the engine ports which has the higher pressure, the end space B communicates with the interior of the casing. A port D<2> also communicates with the latter and ports E, E<1> communicate with a place of low-pressure fluid. When the pressure in the casing falls, the piston valve uncovers port D<2> and fluid from the highpressure port of the engine passes into the casing until the balance is restored. When the pressure is too high the valve uncovers port E and fluid is allowed to escape.

Title: Improvements relating to Circular Knitting Machines and methods for Effecting Make-Up on such Machines
IPC: D04B9/46
Filed: 1968-04-09
Abstract: 1,151,149. Knitting. SCOTT & WILLIAMS, Inc. 9 April, 1968 [11 1 April, 1967], No. 16982/68. Headings DIC and D1K. A method of effecting make-up on bare needles of a superposed cylinder machine comprises locating all of the needles in the lower cylinder of the machine and after opening their latches feeding a yarn so that it is fed into the hooks of the needles, the alternate needles subsequently being raised so that the yarn passes on to their shanks. The alternate needles are then transferred to the upper cylinder whereafter yarn is fed to them only and they are caused to engage the yarn and draw loops which they hold over the next three courses formed by the lower cylinder needles taking yarn and knitting. Subsequently the needles of both beds take and knit yarns the held loops being knitted in with a later course as shown in Fig. 4. Elastic yarn may also be included in the courses. The make-up is achieved by feeding yarn at a single station on a two feeder machine in which the second feeder is initially rendered inoperative but is introduced, for example, at course IX when two feed knitting is commenced. The method is carried out on a two or more feeder machine having a cam set up involving withdrawable cams for deflecting the needles into knitting or non-knitting paths. The sliders have variable length butt arrangements and the upper sliders have an additional butt to allow needle manipulation and transfer to be effected in the required manner. The machine also has adjustable verge bits 80 collectively movable by being mounted in a housing 82 secured to a tube 90 movable up and down under the dictates of a cam controlled mechanism 108 . . . 120. The cams are mounted on a bed 66 secured by a screwed tube 72 and the cam positioning is adjustable during reciprocatary knitting by a control sleeve 68 moving between limits engaged by a stop 70 secured to the sleeve. Pneumatic take down mechanism is provided and in order to deflect the air sream towards the fabric a deflector 132 also is provided pro jecting within the needle circle. Fabric camming fins 78 also assist in the take down of the fabric and the provision of humps 76 in combination with air flow and the fins provide the necessary inwardly and downwardly directed tensions to the fabric as new stitches are being formed. To assist the initial course structure by ensuring that the yarn is received in the needle hooks a latch opener comprising a nozzle which directs a stream of air against the latches to deflect them downwardly into an open position is provided adjacent the needle circle.

Filed: 1939-06-10
Abstract: 530,388. Landing aircraft. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., and LLOYD, J. June 10, 1939, No. 17060. [Class 4] The rear wheels 12 of a tricycle-type undercarriage, which, in the landing position are at a lower level than that of a front wheel of ordinary construction, are mounted on rigid cranked members 22 the main parts of which are pivoted at 24 to the aeroplane and are vertical when in the landing position. A two-stage oleo leg 25 is pivoted intermediate the ends of each member at 23, and to the framework at a point 26 abcve the pivot 24. When landing contact is made, wing flaps 40 arranged to produce lift are replaced by upwardly directed flaps 41 to produce pressure on the tyres so as to obtain the maximum braking effect. When the full landing pressure is exerted on the tyres, the members 22 occupy the position shown in dotted lines. During landing, the line of pressure cf the wheels passes from a position 31 in front of the centre of gravity 30 to a position 32 well behind it. The distance 38 represents the vertical movement of the aercplane during landing and includes the distance afforded by the squashing of the tyres of the wheels 12. The second stage of the oleo legs is used to retract the wheels into the engine " eggs " 16 where they are enclosed by doors 35. Specifications 463,401, 530,386 and 530,387 are referred to.

Title: Allylic rearrangement of chlorine substituted butenes
Inventor: YOUNG DONALD PETER
IPC: C07C17/358
Filed: 1956-06-02
Abstract: The invention comprises a process for the allylic rearrangement of 3-chlorbutene-1, 1-chlorbutene-2, 3 : 4-dichlorbutene-1 or 1 : 4 dichlorbutene-2 by contacting the chlorine substituted butene at an elevated temperature with a copper salt in the presence of an organic amine.  Suitable salts are cuprous or cupric chlorides, sulphates or acetates, and suitable amounts are between 0.1 and 1 per cent by weight of the anhydrous salt based on the weight of chlorine substituted butene.  Suitable organic amines are those which are liquid at normal pressure at the temperature at which the reaction is carried out, e.g. tri-n-butylamine, quinoline, a -picoline, pyridine, o-anisidine, triethanolamine and a C1-C6 monoalkylamine.  Preferable amounts of amines are about 2 to 5 times the weight of the copper salt present.  The reaction may be carried out by dissolving the copper salt in the warm amine and adding the catalyst mixture to the chlorine substituted butene.  Temperatures up to the boiling point of the reaction mixture may be used preferably at atmospheric pressure although increased and reduced pressures may be used.  If the reaction mixture is continuously distilled the lower boiling component is continuously removed.  If the higher boiling isomer is required, however, the starting material should be heated with the copper salt/organic base catalyst until a substantial amount of the desired product has been obtained, the catalyst should then be removed, for example by flash distillation, or by washing with concentrated hydrochloric acid, and the mixture distilled.  The remaining lower boiling isomer may then be reheated.  Mixtures of monochlorbutenes with dichlorbutenes can also be used as the starting material.  Tests are described illustrating the isomerism of 1-chlorbutene-2 and 3-chlorbutene-1, and 3 : 4-dichlorbutene-1 to 1 : 4 dichlorbutene-2 using copper catalysts in the presence and absence of an amine, and an example given of the conversion of 1-chlorbutene-2 to 3-chlorbutene-1 in the presence of cuprous chloride and a -picoline.

Title: Machine for applying screw-threaded corks to bottles or for removing screw threaded corks from bottles
IPC: B67B3/20
Filed: 1960-05-16
Abstract: 948,146. Stoppering machines. J. LEGENDRE. May 16, 1960 [May 16, 1959], No. 17222/60. Heading B8T. A machine for applying or removing screwtop cocks respectively to or from bottles comprises an endless conveyer adapted to carry vertical bottles through the machine at a constant level, and tools for applying or removing the corks to or from the bottles, said tools being slidably suspended from an endless chain above the conveyer and comprising members which engage a guide rail shaped to cause the tools to slide towards or away from the bottles at the appropriate parts of the machine. A machine embodying the invention and for screwing stoppers into bottles, comprises a housing 1, containing motors and gearing for driving the various parts of the machine in synchronism, and supporting an endless conveyer 7 for bottles O and a superstructure 4 carrying the stoppering tools 20. Each tool 20 comprises a stem 23 carrying a stoppering head at its lower end and slidable within a sleeve 22, the sleeves 22 of the various tools being joined by links 28 to form an endless chain, driven by a notched sprocket wheel 27. As the chain is advanced, the sleeves 22 engage tracks 30, 31 on the superstructure 4 and thus always remain at the same level, whilst rollers 32 connected to the stems 23 engage the track 34 and thereby guide the stems 23 to their raised or lowered positions as required during the stoppering process. Stoppers 19 are fed from a hopper 14, down an inclined guideway, and are received in recesses formed in the periphery of a rotating disc 17, ready to be collected by the tools 20 as the latter pass the depression 36 in the track 34. The tools then pass on to the depression 37, where they are lowered to engage the stoppers with the bottles O, which have previously been spaced along the conveyer 7 by the screw 9. The engagement of a stopper with a bottle lifts the corresponding roller 32 away from the track 34, the weight of the stem 23 then urging the stopper downwards. At this point the bottles pass between a stationary plate 10 lined with foam rubber and three superimposed endless belts (not shown), the latter rotating the bottles whilst the stoppers are held stationary within the tools 20. The stoppers are thereby screwed into the bottles, the stems 23 then being raised out of contact therewith. Compressed air is fed from a distributer 50 via tubes 55 to each tool 20 and is used therein, firstly to exert a braking action on the stoppering head and hold the latter stationary during the stoppering process, and secondly to depress piston 43 and deform the rubber ring 42 to grip a stopper 19 firmly.

Abstract: 981,433. Frequency discriminators. PACIFIC INDUSTRIES Inc. May 11, 1961 [Dec. 6, 1960], No. 17309/61. Heading H3A. A frequency discriminator comprises two parallel arms, one including a piezo-electric crystal with series and shunt resonance frequencies on opposite sides of the centre frequency of an input FM signal, and the other arm an impedance producing a zero cross-over of the discriminator output at the centre frequency, both arms feeding the output circuit over rectifiers of opposite polarity. The impedance may be a capacitance Xa of reactance equal to the total capacitance shunting the crystal. A capacitor or inductor may be in series with the crystal to raise or lower respectively the series resonance (zero) frequency or a capacitor or inductor in parallel with the crystal to lower or raise the anti-resonance (pole) frequency. By this the spacing between the lower frequency series resonance frequency and higher frequency anti-resonance frequency may be varied, and the impedance of the crystal circuit altered. An inductor 4 and capacitor 5 in parallel of inductive reactance equal to one half that of the capacitor Xa may couple the FM source to the discriminator to increase its linearity. Alternatively the crystal may be connected to the first arm by an RF transformer; or the second arm may also comprise a crystal and associated circuitry. Further, the detectors 10, 11 may be in series with the output circuit 3. The latter and the FM source are preferably of low impedance.
