Title: Improvements in or relating to process for extracting alumina values from alumina bearing ores
IPC: C01F7/06
Filed: 1951-08-30
Abstract: A process for extracting alumina values from Jamaica bauxite and other ores having a like residue skeletal structure (red mud) by digestion with caustic alkali at elevated temperature (say about 150 DEG C.) and pressure, is characterized by subjecting the slurry to a separation treatment such as filtration or sedimentation at the digestion temperature and pressure, or only after slow reduction of the temperature.  The filtration rate is greater in the case of these particular ores than if the pressure and temperature are suddenly reduced prior to separation of the undissolved material.

Title: Improvements relating to torque transmssion devices
IPC: H02K31/04
Filed: 1958-07-03
Abstract: 927,394. Homopolar machines; automatic speed control. J. SAYERS. July 3, 1959 [July 3, 1958 (2)], Nos. 21279/58 and 21282/58. Classes 35 and 38 (4). A device for transmitting torque between two coaxial shafts 10, 11, Fig. 1, includes two homopolar machines 14, 15 respectively acting as a generator and a motor when the shafts 10, 11 form the respective input and output members, and the machines have a common stator field structure which includes a central annular polepiece 16 and respective excitation windings 20, 21 and rotary armatures 29, 31 connected to the respective shafts; an electrical circuit 40 interlinked with the two magnetic circuits 22, 23 created by the windings 20, 21 exists through the two rotors and part of the stator structure by way of electrical brush means which may be of the liquid mercury type forming the subject matter of Specifications 927,395, 927,396 and 927,397, which are referred to. All portions 27, 28, 16a of the rotors and stator structure lying within a toroidal zone bounded by the electrical circuit 40 and which also convey the working fluxes of the magnetic circuits 22, 23 are formed wholly of interleaved sets of high and low magnetic reluctance laminations 34 33, Fig. 2, at least one set being of low resistivity. The laminations, e.g. of copper and low carbon steel are united together by fusion and have set up in them by rotation of the armature 29 a voltage which causes a current to flow in the circuit 40. Whilst the device may comprise only the two machines, it is shown associated with a differential gearing which includes an input bevel gear 30 fixed to the shaft 10 and to the generator armature 29, and an output bevel gear 58 bolted to the motor armature 31 and connected to the output shaft 11 via bevel gears 56 carried by stub shafts 55 on a cage 32 fast with the shaft. In operation, the torque transmission is shared between the machines and the gearing, and when the fluxes 22, 23 are equal and opposite as shown, and the shaft 10 is rotated the torque is transmitted as the two armatures 29, 31 rotate at equal speeds in opposite directions. If now either flux 22 or 23 is reduced the output shaft will rotate in a direction which is respectively the same as, or opposite from, that of the input shaft. The device, which is shown as 87 in Fig. 5, may be applied to the transmission in a land vehicle, e.g. a motor car, wherein an I.C. engine 88 drives via shafts 10, 11 the road wheels 93a, and a tachogenerator 90 and an amplidyne 92a, 92b which provide control and excitation of the windings 20, 21. The car throttle 91 controls both the engine fuel control 88a and the tachogenerator excitation current provided in a winding F1 by a battery B1. The characteristics of the tachogenerator 90, the amplidyne 92a, 92b and the displacement of the slider of resistor R1 for a given throttle displacement may be so arranged that the conversion effected by the device 87 tends to produce a predetermined engine speed for that throttle setting irrespective of the load encountered by the road wheels.

Abstract: 532,399. Dough-working machines. MOORE & SONS, Ltd., W., and PEARCE, W. S. July 22, 1939, No. 21315. [Class 87 (ii)] In dough moulding machines comprising upper and lower belts travelling in opposite directions between side plates and wherein one belt is movable relatively to the other to apply a yielding pressure, the dough entrance end of the movable belt is normally so disposed as to be lifted by the incoming dough to ensure engagement therewith and without requiring pre-formation thereof. Preferably the movable belt is pivotally mounted about a pivot at its exit end so as to apply increasing pressure to the dough. The dough may be sub-divided into two portions which may be delivered separately. As shown, a lower belt 16 is disposed between side plates 12 and its working surface is supported by a platform 13. The upper belt 27 is supported by rollers 26, 31 mounted in arms 28, braced by members 33 supporting a platform 34, which arms are adapted to pivot about the roller 25 that the roller 31 falls towards the belt 16. The bearings for the axle 30 of the roller 31 are carried by links 38 suspended from a lever 36 counterweighted at 37. Dough portions from a first prover are delivered to the belt 16 and are engaged by the leading edge of the belt 27 and rolled up. Near the exit end the dough is divided by a fixed knife 39 into two portions, one of which is allowed to fall off the belt 16 directly on to a final moulder, while the other falls into a pan 42 linked to a dash-pot 44 so as to be delivered later. The dash-pot may be adjusted to deliver two portions in quick succession e.g. for making a split loaf, or at equal intervals for making separate, smaller loaves.

Title: Method and means for reducing the cross modulation distortion of travelling-wave tube amplifiers
IPC: H03F3/54
Filed: 1968-05-06
Abstract: 1,218,947. Travelling-wave tube amplifiers. ELEKTROMEMECHANIKAI VALLALAT. 6 May, 1968 [5 May, 1967], No. 21419/68. Heading H3W. A method of reducing cross-modulation distortion, of travelling-wave tube amplifiers 24, comprises modifying the input signal to compensate for the distortion at least in part by adding to the input a time displaced signal, derived from the input signal the phase of which is made dependent on the modulation content of the input signal. The input modulated signal is demodulated at 2 and fed via a broad band amplifier 3 to level regulators 4, 5 which control a voltage dependent reactor 8 such as one or more varactor diodes and a voltage dependent resistance 13 such as one or more diodes. The voltage dependent reactor and resistance 8, 13 pre-distort the phase and amplitude of the input to the travelling wave tube amplifier 23 via ports 7 and 15 of a circulator 6 in dependence on the frequency and amplitude of the modulation content. The working points of the voltage dependent reactor and resistance 8, 13 are adjustable by potential dividers 11 and 17. A delay cable 19 connects the modulated output from a generator to the input 20 of the circulator 6 and the lengths of the cable 19 in relation to the distance between the demodulator 2 and the input 20 is such as to compensate for phase delay set up in amplifier 3. The voltage dependent resistance 13 may alternatively be connected to the output 7 (Fig. 4, not shown). The amplifier 3 may include a frequency dependent phase adjuster (21, Fig. 5, not shown) before the amplifier (22) and/or a frequency dependent amplitude corrector which also provide predistortion signals.
