Filed: 1923-01-26
Abstract: 215,056. Lamplough, F., and Fathers, G. H. Jan. 26, 1923. Rolling-machines.-In apparatus for moulding fuel briquettes of the type having two rotatable bevel die-wheels each having on its bevel face dies which co-operate to form moulds, the axes of the die-wheels are at right-angles to each other and the bevel faces meet in a vertical plane passing through the axes at right-angles to the surface of a conveyer belt arranged beneath the die-wheels. The material which may have been mixed or treated in apparatus such as that described in Specification 215,292, [Class 86, Mixing &c.], is preferably fed direct by a shoot to the meeting faces of a pair of die-wheels 17 rotated by bevel gearing 29 from a central driving shaft 30 which also carries a pulley 19 for driving a conveyer belt 18. Dies 21 in the bevel face of the die-wheels co-operate to form moulds from which the formed briquettes are ejected by means of a cam or pusher wheel 22, Fig. 3, coming into contact with the stem of a spring-retracted plunger 23 which is situated in each die and may be engraved to impress a design &c. upon the briquette. A band 26 by which the cam is secured to the exterior of the bearing of each die-wheel can be rotated so as to vary the position at which ejection occurs. The conveyer band is kept taut by means of adjusting screws acting upon the movable bearings of a jockey pulley.

Title: Improvements in or relating to variable speed power transmissions
Inventor: CHAPMAN CHARLES WALLACE
IPC: F16H61/62
Filed: 1958-01-24
Abstract: 906,693. Pneumatic transmission of power. PERKINS Ltd., F. Jan. 15, 1959 [Jan. 24, 1958], No. 2534/58. Class 8(2). [Also in Groups XXIX and XXXI]. A variable speed power transmission comprises a torque converter having an input shaft 13 driven from a prime mover, such as a combustion engine and an output shaft 24 connected to a mechanism to be driven, and a booster for the prime mover driven through a differential gear 29, 30, 32, 36 from the input and output shafts so that when under load the output shaft speed falls to a percentage of the input shaft then the booster rotary speed increases relative to the input shaft speed by a higher percentage. In the preferred embodiment, the torque converter, which may be hydrostatic, pneumatic or electro-magnetic, is of the hydro-kinetic type having an impeller 16 secured to a casing 14 connected to the input shaft 13, a turbine 22 splined to the output shaft 24, and a reactor 20 connected to a one-way free-wheel device 20 to a stationary stub shaft 18 secured to a fixed outer casing 10. The impeller, and hence the input shaft, is connected to a gear 27 meshing with a gear 29 of the differential, and a gear 28 on the output shaft meshes with a further gear 30 of the differential. The gear 29 is rotatably mounted on a shaft 35 and secured to a planet carrier 31 carrying gears 32 in mesh with an internallytoothed ring gear 7 which is secured to the gear 30 and engages a gear 36 formed on the shaft 35 rotatably mounted in bearings 6 in the fixed casing and connected to the booster (not shown). When starting a vehicle from rest with full throttle, the output shaft is stationary and the input shaft rotated at high speed. The differential gear, depending on its ratio, drives the booster, which may be a supercharger, turbo-blower or Roots blower, at a correspondingly higher speed. As the vehicle accelerates and the difference in speeds of the input and output shafts decreases, the speed of the booster will decrease until when both shafts rotate at substantially the same speed, the speed of the booster will be directly related to the engine speed. If the speed of the output shaft decreases, the relative increase in speed of the input shaft to that of the output shaft will increase the speed of the booster. The gear 27 on the input shaft also engages a gear 37 driving gear pumps 38, 39, the former pumping drained oil from a sump 43 to an external tank, filter and cooler, and the latter supplying oil under pressure to the converter and for lubrication purposes. Oil from the pump is also passed, under the control of a valve actuated manually or by a device sensitive to speed, torque or engine boost pressure, through a sleeve on the shaft 24 and passages 5 to an annular piston 41 to operate a clutch 40 and connect the turbine 22 to the impeller casing 14 for direct drive. A forward-andreverse gear may be incorporated in the transmission.

Title: Improvements in or relating to titanium production
IPC: C22B34/12
Filed: 1958-01-27
Abstract: Alkali metal chlorotitanates are prepared by partially dissolving a titanium ore, e.g. ilmenite, in a strong mineral acid, and then treating the solution with hydrogen chloride gas and an alkali-metal halide to obtain a precipitate of alkali-metal chlorotitanate, which is dried by the process of Specification 838,822.  Thus, ilmenite may be treated with sulphuric acid, the solidified mass leached with dilute sulphuric or sulphuric and hydrochloric acids, and the iron in the resulting solution is removed by cooling to crystallize out the major portion of the iron and then saturating the solution with hydrogen chloride at low temperatures, e.g. -10 DEG C. to -20 DEG C. to precipitate the remaining iron.  Potassium chloride is now added to the solution and the precipitate dissolved in hydrochloric acid from which it is reprecipitated by cooling and adding hydrogen chloride. Lithium, sodium, potassium, rubidium and caesium are referred to. Specification 883,722 also is referred to.ALSO:A method of producing titanium comprises heating a mixture of a dried alkali metal chlorolitanate, containing not more than 0,01% of physically or chemically bound water, with an alkali metal in an inert atmosphere at 250 DEG C. to 600 DEG C. and separating the titanium from the other reaction products.  The alkal metal chlorotitanate and the alkali metal may be ground to a particle size of 1-10 microns, intimately mixed and formed into pellets before heating; all the operations being performed in an inert atmosphere, e.g. in argon or helium gas or in a vacuum.  The chlorotitanate may be dried by heating to 20 DEG C. to 300 DEG C. in a stream of hydrogen chloride gas.  The reaction products may be separated from the titanium by leaching with dilute hydrochloric acid or by vacuum distillation. After first precipitating the chlorotitanate from acid solution by hydrogen chloride the chlorotitanate may redissolved and reprecipitated before any which operation is stated to improve the quality of the titanium produced.  Specifications 838,822, 883,722 and U.S.A. Specifications 1,437,984 and 2,205,854 are referred to.

Class 20(2) A mine roof support comprises two sets of props A1, B1 and A2, B2, Figs. 1 and 2, the props in each set being connected by roof bars Cl, C2 and floor bars D1, D2 respectively and the two sets being interconnected by linkages L, P and F. G between the roof and floor bars to allow them to be advanced relatively to one another. In order to allow the props to be inclined to the roof and floor bars and to maintain the props normally vertical the props engage the roof and floor bars by curved surfaces 112, Fig. 3, and rubber bushes 115 are arranged between and bonded to these parts. The props are extensible and retractable and a jack E connected between the floor bars is adapted to move the sets forward alternately by taking its abutments on the set extended between the floor and the roof set and moving the retracted set. The pit props and the jack E are controlled by an hydraulic system, Fig. 4, comprising a delayed selector valve 5 which connects the appropriate end of the jack E to the high pressure duct when the pressure drops in one set of props, e.g. A1, B1 which causes valves 1, 2 to open influencing the valve 5 through pipes 3, 4. Restrictions in the end ports of the valve 5 delay operation of the jack to allow the props to drop clear of the roof. At the end of its movement the piston rod of the jack E engages a mechanical trip 18 which recloses the release valves 1, 2 of the props A1, B1 and opens a valve 19 to connect the props to the high pressure duct to extend them against the roof and the pressure in the props acts through ducts 23-25. on a piston 26 to operate release valves 30, 31 for the other set of props A2, B2 to continue the cycle of operations. A trip 36 operated by a mining machine may actuate a rod 35 to open the valves 1, 2 so that the cycle is repeated automatically at intervals. Specification 786,332 is referred to.
