Abstract: 1,176,656. Eddy current brakes. SANGAMO WESTON Ltd. 10 April, 1967 [15 April, 1966], No. 16698/66. Heading H2A. [Also in Division G1] An eddy current brake is used in an electrical measuring instrument (see Division G1) to prevent overshoot when the required indication is reached. A copper damping disc 24 secured to shaft 20 rotates between the poles of U-shaped magnet 25 which is mounted on pivot 27 and biased by spring 27 so that when the disc is stationary the area of intersection of the poles with the disc is maximum. When the disc is rotating the magnet 25 is displaced by interaction until its poles are nearly clear of the disc to provide minimum braking effort but as it slows or reverses the magnet will be returned to the maximum braking position to reduce the amount of overshoot. A conductive vane 28 attached to magnet 25 moves between the poles of a further magnet 29.

Title: Improvements in or relating to method and apparatus for measuring and controlling the level of the molten glass in tank furnaces
IPC: G05D9/12
Filed: 1951-07-16
Abstract: 690,261. Automatic level control systems. UNION DES VERRERIES MECANIQUES BELGES SOC. ANON, and BRICHARD, E. July 16, 1951 [Sept. 7, 1950], No. 16825/51. Class 38 (iv). [Also in Group XVIII] A method of regulating the level 3 in a tank 1 of molten glass comprises directing a constant delivery jet of gas, e.g. cold air, from an outlet in a pipe 6 on to the surface of the glass at a point 5, and utilizing the pressure variations in the air delivery, consequent on changes in the glass level, to operate means for regulating the delivery of glass. A fan 17 delivers air to an adjustable nozzle 11 through the pipe 6, the pressure in which acts on a water-filled manometer 18, 20. A float 21 in the limb 20 is connected to a wire 22 fixed to a pulley 23, the spindle 24 of which carries a needle 26, 27 which alternatively contacts two electric contacts 34, 35, each in a relay circuit 32, 33 respectively. Glass is delivered to the tank by a compound-wound motor 43, the armature 44 of which is in series with a resistance 45 and in parallel with a rheostat 46, the slider 47 of which is controlled by a reversible motor 52, Fig. 8. Energization of one of the relays 32, 33 initiates the two following operations. Firstly, resistances 56, 57 in series with the field coil are short-circuited or brought into circuit respectively to vary the speed of the motor 43, and secondly an electromagnet 55 is appropriately energized to actuate one or other of two double contacts 53, 54 to determine the direction of rotation of the motor 52 and hence the value of the rheostat 46. The time during which the speed of the motor 43 is controlled is made proportional to the deflection of the needle 27 by employing contacts 34, 35 of the shape indicated in Fig. 7. A constantly rotating cam 41 periodically deflects the needle 27 an amount " d," and depending on the extent of the right- or left-hand deflection of the needle 27 due to the pressure variations, so is the time during which it touches the contact 34 or 35 determined. Precautions may be taken to cool the glass at the point 5 to prevent wrinkling, e.g. by water-cooling the nozzle head 11 and shielding the glass at 5 from the tank atmosphere. The manometer may be replaced by a pendulous torroidal pressure gauge, (see Fig. 2, not shown), to permit one arm of the device to communicate with the tank atmosphere to eliminate the effects of pressure variations in the tank.

Abstract: 236,929. Bliss Co., E. W., (Assignees of Strout, R. W.). July 10, 1924, [Convention date]. Clutches, claw.- In rocking segmental-key clutches, a spring connected to the key and to a rotatable anchor-piece, capable of being locked in two positions, serves both to actuate the key and to hold the anchor-piece in engagement with its locking- means. A clutch of the type described in Specification 211,280, applied to a press, comprises a key A, carried by the driven shaft B, and normally held by its lug D out of engagement with the fly-wheel C against the action of a helical torsion spring E, the ends of which engage slots k, l in the key and an anchor-piece G. The part G has means such as a polygonal socket in its end, for rotating it to stress the spring to cause clutching or, to a less extent, to reverse the stress to hold the key out of action (as when setting the dies), and is provided with a part-circumferential groove M terminating in axial grooves P, Q, which can engage a pin N in the shaft B under compression or tension of the spring E. The grooves P, Q may terminate in short, reverted circumferential grooves, as shown at P<1>, Fig. 6, so that the spring torsion holds the parts locked.

In apparatus in which a readily evaporable liquid is transferred to a container 6 from a first container 2 under gaseous pressure supplied through pipes 4, 4<SP>1</SP> whereby equipment in close proximity to the apparatus is cooled by evaporation of the liquid, the increase in gaseous pressure in a control tube 7 caused by the liquid level in the container 6 rising above the open end 9 of tube 7 operates a valve 11 to release pressure from container 2 by venting gas through pipes 4, 4<SP>1</SP>. A fluid logic system is described in which the pressure in the control tube is applied as an input control signal to a pure fluid amplifier, the output of which controls the venting of gas from the first container, and a pressure take-off between the pipes connecting the first two containers may be fed through a restrictor to the fluid amplifier to limit the pressure in the first container. The working gas may be the vapour of the liquid in the first container and the tube 7 may contain an absorbent material so that the cycling time of the apparatus may be lengthened.

Classes 59 and 82 (1) [Also in Group XII] Fine materials, for example coal, in the form of coherent moist lumps, are subjected to-a disintegration process and the resulting small aggregates are then subjected to an oscillatory motion having a horizontal direction to produce larger agglomerates. The larger agglomerates are caused by the oscillatory motion to progress through a plurality of parallel trough-like zones whose individual axes are located perpendicular to the direction of movement of the particles. The disintegrator comprises an inner cylindrical basket 1 with a conical bottom 9 and spaced cutting wires 10; rotatable about preferably a vertical axis, and an outer basket 2 also rotatable but at a slower speed and preferably in the opposite direction. This outer basket is also provided with spaced wires 13. The baskets 1 and 2 are rotatable by pulleys 7 and 8 respectively.

Abstract: Ni and Co values are recovered from lateritic and garnieritic ores containing Ni and Co in oxidic form by heating the ores to 430-820 DEG  C. with a reducing agent (e.g. H2 and/or CO); dispersing the reduced ore, containing metallic Ni and Co, in water to form a slurry, treating the agitated slurry at ambient temperature and atmospheric pressure with an oxygen-bearing oxidizing gas and SO2 until substantially all the Ni and Co are extracted as water soluble sulphates.  The SO2 may be added in gaseous form mixed with the oxidizing gas (preferably less than 15% by vol. SO2) or it may be formed in situ by adding a calculated quantity of soluble sulphite to the slurry. The separated solution of NiSO4 and CoSO4 may be treated with a sulphiding agent (e.g. H2S) to precipitate the mixed sulphide from solution.  The leach solution after separation of the residue and recovery of the Ni and Co as sulphides may be recycled to the slurrying step to fully utilize the unreacted dissolved SO2.
