Title: Improvements in or relating to automatic variable speed transmissions
IPC: F16H47/08
Filed: 1948-05-31
Abstract: 655,487. Variable speed gear. CLEVELAND, F. J. (Windfields (1946), Ltd.), and WINDFIELDS (1946, Ltd. May 31, 1948, No. 14621. Addition to 639,675. [Class 80(ii)] An automatic variable speed transmission comprises a fluid torque converter having first and second speed runners driving gearing connected with an output shaft and a reaction member held against backward rotation by an overrunning clutch, and clutch means controlled by a speed and torque sensitive governor for interconnecting the converter input member with the geartrain reaction member for providing high speed or direct drive. As shown, an input shaft 1 drives the impeller 2 of a torque converter A, the first and second stage stage runners 3, 4, of which drive. through hollow shafts 11, 15, two sun gears 16, 17, which, meshing with stepped planet gears 24, 25 drive a shaft 28 through gears 26, 27. A torque spider 45 splined to the shaft 28 has arms 46 engaging fulcrum blocks 44 in weights 41 pivoted on pins 42 in a drum 40 secured to a transmission shaft 8 and so arranged that the gear drive opposes the centrifugal force of the weights. Attached to one weight 41 is a link 52 actuating a fluid controlling piston valve 51 in a bore 50 of the shaft 8. The planet carrier 20 carries a normally disengaged hydraulically actuated friction clutch comprising discs 29, 30 secured to the carrier 20 and converter housing 5, and engagement is effected by an axially moving piston 33 to which fluid pressure is applied via a passage 54. In operation, first and second gear drives are respectively from the runners 3 or 4, through the planetary gearing and governor to the tail shaft 10, via reversing gearing, the weights being withdrawn and a clutch 12 overrunning in second gear. On speed increase or torque reduction in the latter gear, the centrifugal force of the weights 41 overcomes the torque reaction thereby moving valve 51 to permit fluid flow through conduits 53, 54 and engaging the clutch yielding direct drive from the casing 5. Returning to second gear for acceleration is effected by kick-down of the .accelerator pedal which, by a cable 58 actuates an auxiliary valve 57 to interrupt the fluid supply and disengage the clutch. A band brake 80 actuated simultaneously with the valve 57 permits engine braking.

Title: Improvements in or relating to a manually operable towing unit and trailer combination
IPC: B62B1/08
Filed: 1958-05-08
Abstract: 924,067. Hand trucks. WILLMOT TRUCKS Ltd., and F. G. COZENS. May 6, 1959 [May 8, 1958 (2)], Nos. 14696/58 and 14697/58. Class 108(1). A hand truck towing unit and rear wheeled trailer combination, Figs. 1 and 3, comprises a right angled arm 29, 30 mounted on the towing unit which supports a ball 28 adapted to engage in a socket on the trailer, and the combination is provided with a latch mechanism which prevents the ball from jumping out of the socket when engaged therein. The socket member 5 on the trailer comprises skirt portions 12 joined at the bottom by a saucer shaped portion 10 provided with a. hole 11, and the towing unit is provided with a body 13 having a boss 22 rigidly supporting the arm 30, stem 29 and ball 28. A tubular handle forked at its lower end 41 is pivoted to the body at 26 and contains a plunger 42 which may be lifted or lowered by pivoting a lever 44 and sliding a block 45, the plunger being accommodated in either of two sockets 23, 24 in the boss 22 to permit the handle to be altered in inclination. In the Fig. 3 position of the handle the plunger bears on a shaft 38 forming part of an S- shaped yoke 32 pivoted at 27. The shaft 38 on the yoke may be swung about the pivot 27 in a bore 25 by operating the plunger so that the yoke may pivot upwardly or downwardly against a spring 37, thereby entering or removing a spigot 35 from the hole 11 in the portion 10 when the ball is engaged within the socket. When the spigot 35 is in the position shown in Fig. 4 it may enter the hole far enough to press against a convex undersurface on the stem 29 and arm 30, thus locking the ball and socket together but not preventing angular movement between them. In operation, the handle is located as shown in Figs. 3 and 5 and the plunger 42 is depressed by moving the lever 44 to lower the yoke 32 and bring the spigot 35 away from the stem 29. The towing unit is then tilted in one direction about its main wheels to bring the head 28 between the boss 8 and extension 10 and into the socket, and then the unit is tilted in the opposite direction to dispose the portion 10 between the stem 29 and the yoke 32. The lever 44 is then centralised to withdraw the plunger partly from the socket 24, thus allowing the spring 37 to move the yoke 32 upwardly and engage the spigot 35 in the hole 11. An alternative method of coupling the towing unit to the trailer is also described.

Patent GB-587070-A (GB)
Title: Improvements in or relating to the removal of oxygen from gases
IPC: B01D53/46
Filed: 1945-10-09
Abstract: Oxygen is removed from a gas containing free hydrogen by bringing the gas into contact with a catalyst consisting of or containing a subsulphide of nickel or of cobalt and a promoter therefore at a temperature above 50 DEG C. and preferably below 200 DEG C.  The promoter must be present in the form of a compound in an amount not exceeding 20 atoms of promoter element to 100 atoms of catalyst metal.  Suitable promoters include copper, cadmium, aluminium, molybdenum, tungsten, iron, and cobalt (for nickel-subsulphide) or nickel (for cobalt subsulphide).  The catalyst may be supported on clay, activated alumina or active charcoal.  The main catalyst metal and the promoter may be co-precipitated in the form of hydrated oxides or carbonates the precipitate being washed, dried, formed into pieces, converted into sulphides by treatment with hydrogen sulphide or with carbon bisulphide vapour at elevated temperature and reduced to subsulphide by reduction with hydrogen or gases containing hydrogen at 300-500 DEG C.  Alternatively the co-precipitation may be carried out to yield sulphides which are reduced by hydrogen to subsulphides.  Particularly when preparing supported catalysts, the initial salt of the catalyst metal contains both sulphur and oxygen and is reducible at elevated temperature by hydrogen, and the initial salt of the promoter element may be of similar kind, or alternatively an ammonium salt of an acidic oxide or sulphide. According to an example china clay pellets are heated in a boiling aqueous solution containing nickel and copper sulphates, drained, dried, and reduced in a stream of coal gas at 350-400 DEG C.  The invention may be employed in the treatment of hydrogen, coal gas or water gas. Specification 530,983 is referred to.

Abstract: 1460895 Aircraft undercarriages DOWTY ROTOL Ltd 27 March 1974 [30 March 1973] 15395/73 Heading B7G A levered suspension undercarriage for aircraft is so arranged that when fitted to an aircraft which is in a level condition with the undercarriage fully-extended a shock absorber connected to the suspension lever has its longitudinal axis inclined with respect to the vertical plane containing the longitudinal axis of the suspension lever. A leg 11 carried by main pivots 14, 15 for sideways retraction carries a suspension lever 17 which is biased by a shock absorber 23 the upper end of the cylinder of which is connected by a pivot 27 to a link 28 fast with one end of a shaft 29 mounted on the leg by pivot 30, 31. The other end of the shaft carries a further lever 51 pivotally connected at 52 to a link 53 in turn connected at 54 to a bellcrank 55 having a mounting 56 on the leg 11. The bellcrank is also connected at 59 to a further link 58 connected at 60 to a toggle linkage form of bracing strut 37 mounted at 39 on aircraft structure. The strut 37 carries a down-locking means 44; a spring box 32 is connected at 33 to the leg 11 and at 36 to the link 28 and a main retraction jack 46 is connected at 48 and 50 respectively to the aircraft structure and the leg 11. A door 62 is linked at 63 to the undercarriage. With the undercarriage in the down position shown in Fig. 2 the longitudinal axis YY of the shock absorber 23 is inclined with respect to the vertical plane XX containing the longitudinal axis of the suspension lever 17. To retract the undercarriage from this condition, locking means 44 is released and jack 46 retracted thereby folding strut 37 about its pivots 39, 40, 42 and allowing the leg to retract. At the commencement of this movement link 58 rotates bell-crank 55 in a clockwise direction, as viewed in Fig. 2, and this acts through link 53, lever 51 and shaft 29 to cause link 28 to bodily lift the shock absorber 23 and rock lever 17 and the undercarriage wheels upwardly before they enter the fuselage recess 64 to be retained by uplock 65. In this operation the spring box 32, which urges link 28 hard against leg 11 in an over centre condition to support the shock absorber in its desired condition, is initially compressed to store energy for use in the final stage of retraction.

Title: Process for producing deposits or coatings from aqueous suspensions of rubber
IPC: C09D5/44
Filed: 1928-05-29
Abstract: 291,339. Anode Rubber Co. (England), Ltd., (Assignees of Compagnie GÚnÚrale d'ElectricitÚ). May 27, 1927, [Convention date]. Moulding by dipping.-In forming deposits, coatings, &c. in or on moulds, supports, &c. from aqueous suspensions of rubber, additions of gelforming substances are made to the suspension &c., and the suspension &c. is subjected to temperature changes to cause the formation of gels. Suitable additions are gelatine, agar-agar, carragheen moss, albumens. The treatment causing gelling varies with the substance employed. Thus the gelling of gelatine is caused by lowering the temperature, for example, by the introduction of a cold mould, or an albumen containing substance may be heated. Electrolytes or suhstances having a coagulating influence may also be employed, such being for example, added to porous moulds. Substances which assist gel formation such as sulphates, acetates, tartrates, sugars may be added to the suspensions, and substances such as acids, alkalies, &c. which might cause hydrolysis may be removed or neutralized. After deposition, the gel may be removed or rendered insoluble. Deposits may be produced by several dipping &c. operations, the film produced being dried, coagulated, &c., between each, in which case the gel-forming substance swells on being again brought into the liquid, and assists in the formation of the subsequent layer. The Specification as open to inspection under Sect. 91 (3) (a) describes the deposition from organic dispersion or solutions generally, examples being given of the formation of shaped articles of ceramic material, and papier mache. Other gel-forming substances, such as zinc chloride, are specified, and methods other than temperature changes may be employed for gelling. This subject-matter does not appear in the Specification as accepted.
