Title: Electronic tool run-out indicator for use in deep boring operations
IPC: B23B41/02
Filed: 1962-01-18
Abstract: 989,190. Boring-machine details. W. A. FOLSOM, and A. L. DE GRAFFENRIED. Jan. 18, 1962, No. 1943/62. Heading B3C. [Also in Division G1] The extent by which a hole being bored in a cylinder deviates from the centre line is measured electrically and energizes an alarm when the deviation exceeds a predetermined value. As shown (Fig. 1), a rough forged gun barrel 10, with its outer surface 12 accurately finished, is mounted on ball-bearings 18 and rotated via gears 20, 22 by a motor, not shown. These rotations define the axis 16 of the cylinder. The inside is drilled by a boring head 26 mounted on a bar 24 which is continuously advanced along the axis 16. In front of the boring head 26 is mounted a run-out sensor 34 which, in a first embodiment, comprises a pendulum hinged on the axis of the boring head 26, and attached to the rotor of a synchro whereby the amplitude of the angle of swing of the pendulum is determined, and is said to be approximately proportional to the distance between the axis of the boring head 26 and the axis 16 of the barrel 10. The sensitivity of the meter measuring this distance is decreased as the bore head 26 travels along the barrel 10 so that a run-out alarm may be given at the same predetermined reading on the meter. Transducer constructions.-The pendulumtype transducer (Fig. 5) is mounted in a cylindrical steel shield 86, and comprises an unbalanced disc pendulum 114 attached by shaft 112 to the rotor 111 of a synchro 88, the leads 110 being taken out through a hollow extension 94 of the shaft 112, which also carries an inertia mass 122. Both windings of the synchro may be fixed, with the shaft carrying a shaped iron core to vary the coupling. An alternative transducer (Fig. 7) comprises a glass case 140 with symmetrical electrodes 142, 144 and a common electrode 146, and containing an electrolyte 148. When the case is horizontal, the resistances from electrode 146 to electrodes 142, 144 are equal, and any subsequent unbalance, measured on an A.C. bridge, is indicative of the lateral movement of an air bubble 150 due to tilt. A further form of tilt transducer (Fig. 10A) comprises a hollow metal sphere 154 electrostatically supported between three electrodes 156, 158, 160 by charging the elements negatively. The differential capacitances formed by electrodes 154, 156, 158 are connected in an A.C. bridge circuit which is unbalanced by lateral displacement of the sphere 154, the unbalance signal being fed to a servo link 165 which adjusts the charging potentials of electrodes 156, 158 to reposition the sphere centrally. The change in potential is indicative of the displacing force and acceleration.

Title: Improvements in or relating to process for the production of coarse grained alumina hydrate from aluminate liquors
IPC: C01F7/144
Filed: 1952-01-29
Abstract: <PICT:0696465/III/1> Coarse grained hydrated alumina is produced by precipitation from a fresh portion of super-saturated aluminate solution in the presence of the coarse fraction of a previously precipitated and classified hydrate, whilst agitating the mixture, and the fine particles precipitated are separated from the enlarged coarser particles formed by growth of the seed particles.  In one procedure, alumina is precipitated in the presence of relatively fine seed particles and the slurry passed to two cone classifiers.  The fine hydrate slurry is used as seed for a fresh initial precipitation, and the coarse hydrate underflow passed in part to washing, filtering and drying apparatus, and in part, as seed, to a tank supplied with fresh aluminate liquor.  When the precipitation has reached a point at which aluminacaustic weight ratio is about 0.4, the air lift agitation is discontinued, and natural classification is allowed to begin.  About half of the slurry, containing the largest crystals, are pumped to a quiescent settling tank, and the balance passed to the first of the two cone classifiers above referred to, to which is also passed the finer hydrate slurry from the quiescent settling tank.  The coarse particle fraction from the latter, containing not less than 70 per cent by weight of particles of plus 200 mesh size, passes to an elutriator, and thence to filtering, and drying or calcining zones.  In Fig. 2, fresh aluminate liquor is pumped from tank 65 to a series of precipitating tanks 50, 50a-c.  Precipitation occurs in tank 50 in the presence of fine seed from storage tank 55.  After stratification, the coarser particle fraction is pumped to a settling tank 51, and the coarser particle fraction therefrom to the second precipitating tank 50a, and so on through the series of tanks.  The fine particle fractions from all the settling tanks 51, 51a-c pass to thickener 61, and thence to storage tank 55, the spent liquor passing to the alumina-digester 64. The final coarsest particle slurry from tank 51c passes to wet screening 67 or hydraulic classification 68, and thence to filter 71, and drier 73 or calciner 74.  The coarse particle slurry is discharged from tank 51c by injection of water, or the filtrate 78 from filter 71.
