Patent GB-621619-A (GB)
Title: Process for production of magnesium carbonate
IPC: C01F5/24
Filed: 1946-03-22
Abstract: Solid neutral magnesium carbonate is produced by reacting a hydrous slurry containing calcium and magnesium hydroxides with magnesium bicarbonate to convert at least a substantial part of the calcium to calcium carbonate, subjecting the resulting slurry, preferably after thickening, to controlled carbonation to convert magnesium hydroxide to magnesium carbonate of particle size greater than about 200 microns, and removing the bulk of the magnesium carbonate as an underflow by hydraulic separation. Carbonation, e.g. with flue gas, is controlled so that the rate of conversion of magnesia to carbonate does not exceed 0.03 mols. per litre per hour and that the carbonate and bicarbonate concentration is maintained within the limits of about 0.02 to 0.05 mols. per litre.  Dolomite may be calcined, slaked, diluted and classified to remove silica, to produce the original slurry. The overflow containing calcium carbonate and some magnesium carbonate may be rapidly carbonated with 25-30 per cent CO2 flue gas to dissolve all the magnesium as bicarbonate, and the filtrate from calcium carbonate recycled to the main process.  The magnesium carbonate may be heated to form basic carbonate or the oxide batch or continuous carbonation with or without seeding may be used.  A continuous centrifuge may be used for separation. Specification 595,284 is referred to.

Title: Improvements relating to the manufacture of glass barrels for syringes and of like tubular articles
IPC: C03B23/049
Filed: 1939-03-22
Abstract: 526,688. Glass manufacture ; moulding plastic substances. EVERETT, S. J. March 22, 1939, No. 9051. [Class 56] [Also in Group V] Relates to the method of making barrels for hypodermic syringes, burettes, and like tubular articles by shrinking a glass tube on to a mandrel. According to the invention, the tube is heated in a liquid bath to a temperature above the softening point of the glass and, at the same time, is subjected externally to pressure to cause it to conform to the mandrel. The method may be used also with non-metallic material which becomes plastic at a moderately high temperature. In operation, one end of the tube is closed and, after the mandrel has been inserted, the open end is connected to a suction pump. The tube is then inserted in the heating- bath which may consist of a salt or of a molten metal such as lead. In the latter case, evacuation may be dispensed with as the weight of the metal causes the plastic glass to shrink on to the mandrel. A tube may be shrunk to the required dimensions in stages on a succession of mandrels. Specification 495,798 is referred to.

Title: Improvements in and relating to stop mechanism for talking machines
IPC: G11B17/02
Filed: 1929-03-21
Abstract: 328,095. Garrard Engineering & Manufacturing Co., Ltd., Offen, F. J., and Butler, W. March 21, 1929. Brakes.-Relates to automatic stopmechanism of the kind comprising a screw spindle rotated by the turntable and a pawl engaging said screw and moved by the tone-arm. According to the invention, the screw spindle c is mounted for longitudinal displacement so that when the traverse of the pawl g due to the angular displacement of the tone-arm o is less than the advance of the screw-thread d on the spindle c due to the rotation of the spindle, the spindle is longitudinally displaced and releases a spring stressed braking mechanism which stops the turntable. As shown, the spindle c is slidably mounted in lugs e, e on a carriage f and is rotated by the shaft of the turntable b<1> through a worm gear a, b. The pawl q is pivoted at q<1> on a lever p pivoted at p' and formed with a slot p<1> engaged by a pin o' on the tone-arm. The pawl is held against the screw thread by a spring r. When, at the end of a record, the tone-arm and therefore. also the pawl stops moving while the turntable and the screw spindle continue to rotate, the spindle moves towards and deflects a lever m about a pivot n, and this releases a lever j<1> with a brake pad which is applied by a spring j<3> to the turntable. At the 'same time, the lever j<1> releases a lever g<1>, which then allows a spring f<1> to turn the carriage f about the axis of the turntable and thus withdraw the screw thread beyond the reach of the pawl q, which is limited by the abutment of a pin q<2> on the pawl against a plate s on the bed-plate z. To restart the machine, the tone-arm is moved back, and the brake swung out of action by a handle j; the lever j<1> is then again caught by the lever m under the action of a spring m<1>, and lever carriage f is returned to the operative position by the lever g<1>. If desired, the manual resetting of the brake may be avoided by the provision of a double-armed lever t, t<1> pivoted at t<2>. With this arrangement, when the tone-arm is moved back to the starting position, the lever t, t<1> is deflected by the lever p and swings the brake lever j<1> to the cocked or inoperative position.

Title: Improvements in automatic condition control apparatus
IPC: G05D1/00
Filed: 1955-03-31
Abstract: 806,303. Automatic steering control systems. MINNEAPOLIS-HONEYWELL REGULATOR CO. March 31, 1955 [April 1, 1954], No. 9442/55. Class 38 (4). In a system for automatically maintaining a variable at a desired value, an error detector, normally coupled to a generator signals from which correct the variable through a servo system, is automatically uncoupled during manual control of the servo system, the error signal produced by the generator being maintained at its value at the instant of changeover. In an automatic aircraft pilot, Fig. 1, bank altitude is maintained by a gyro vertical 35 operating a potentiometer 28 in the input circuit of an amplifier relay 16 controlling a reversible servomotor 14 operating the ailerons. Positional follow-up is provided by a potentiometer 22. Co-ordinated control of the rudder is obtained by also applying the output of potentiometer 28 through a potentiometer 109 to the input of an amplifier-relay 94 controlling rudder servomotor 90. Positional follow-up in the rudder channel is provided by a potentiometer 98 and rudder trim by a potentiometer 101. A predetermined course is maintained by a directional gyro 66 movements of which on deviation from course are transformed into movements of a shaft 50 through an electric correspondence control system involving an inductive pick-off 77, an amplifier 83 and a servomotor 85. Rate and positional follow-up for servomotor 85 is provided by generator 87 and inductive device 80 respectively. Automatic course correction is effected by shaft 50 adjusting a potentiometer 44 in the input of aileron amplifier-relay 16. The course may be altered by manually operating a potentiometer 39 in the input of amplifier-relay 16 and the opening of contacts 129 when this is done de-energizes an electromagnetic clutch 51 between shaft 50 and potentiometer 44 to prevent control by gyro 66. To facilitate smooth changeover, a brake 56 maintains potentiometer 44 in the position it had at the time of changeover to manual control. If, however, it is desired to set a new course by direct manual control of the rudder and ailerons, a push button 124 is operated momentarily to energize brake release winding 58 so that potentiometer 44 is re-centralized by springs 60, 61. In a modification in which gyro 66 directly operates potentiometer 44 through clutch 51, springs 60, 61 are dispensed with to avoid load on the gyro and recentralization is effected by pressure of a plunger on a heart-shaped cam when a solenoid, which also releases the brake, is de-energized by the operation of push button 124.
