Abstract: 195,923. Aktiebolaget Vaporackumulator. April 8, 1922, [Convention date]. Addition to 180,699. Automatic gear.- T h e pressure or pressures and speed governor, which control the admission to the motor in the plant described in the parent Specification, are caused to act on a single throttle valve or other regulating- device of the motor. The motor is controlled by a single valve 6 operated by a servomotor 5, the valve 7 of which is connected by rods 8, 10 to a plate 11 acted on by a spring 12. The plate 11 is controlled by a speed governor S and fluidoperated pistons or diaphragms &c. 13, 14. Rise of the pressure acting above the piston 14 depresses the plate 11 and the valve 7 and causes the valve 6 to close, while rise of the pressure acting below the piston 13 allows the plate 11 and valve 7 to rise and consequently opens the valve 6. When certain limits of speed are exceeded, the governor S acts by means of stops 25, 26 on a rod 24, carried by a lever 23 operated by the governor. In order to permit the governor to raise the plates 11 against the action of the pistons 13, 14, the piston-rods of the latter act on the plate 11 by means nf pins 19, 20 sliding in the rods and acted on by springs 21, 22.

Title: Improvements in or relating to the precipitation of alumina
IPC: C01F7/144
Filed: 1964-04-14
Abstract: Alumina hydrate is prepared from pregnant sodium aluminate solution by first treating with a relatively coarse seed alumina hydrate, of which at least 75% will not pass through a 325 mesh (Tyler) screen, to precipitate a major proportion of the precipitatable alumina hydrate. Afterwards a relatively fine seed alumina hydrate, of which at least 60% passes through a 325 mesh screen, is added to complete the precipitation.  The process may be carried out in two stages where the coarse-grained alumina obtained in the first stage is separated and the liquor passes to a second stage to precipitate the finer alumina hydrate.  The second stage may be initiated when at least 85% of the alumina has precipitated.  The fine grained alumina hydrate obtained in the second stage may be divided into two parts; the first part being used as seed in a subsequent stage and the remainder removed and treated with fresh sodium aluminate to coarsen the particles. The coarsened particles obtained may then be used as seed in the first stage precipitation.  The molten liquor from the coarsening stage may be forwarded to the second precipitation stage for treatment with fine seed alumina hydrate.  In an alternate embodiment, the fine seed alumina hydrate may be added to the depleted aluminate liquor of the first stage before separation of the coarse grained alumina hydrate.

[Also in Group XXXV] A tuner particularly for television receivers comprises an inductor the turns of which are intercolated with a set of non-magnetic, conductive plates, movable by means of a push-button arrangement. As shown, the inductor comprises a number of loops 12 retained in a plate 11 and connected in series by means of straps 13. The tuning is varied by means of copper plates 15 mounted on a carriage 14 and pivoted at 17. A pair of treadle bars 21 are coupled to the movable carriage 14 via members 22, 24. The setting of the treadle bars 21 and hence the tuning of the inductor 12 is adjustable by means of plates 20 pivoted to rods 19 carrying push buttons 18 but preset at a given angle corresponding to the television channel required. The plates 20 are locked against the flat rods 19 by means of a spring strip 19a, the end of which is forced into a tapered sleeve 26 by pressure on the push button 18 to the left. When it is desired to reset any push button 18 to a different channel, the carriage 14 is first adjusted manually to the required channel, the appropriate push button 18 is then withdrawn to the right as shown in Fig. 2, releasing the plate 20. When the push button 18 is depressed the plate 20 takes up the angle between the treadle bars 21 and the spring strip 19a is forced into the tapered socket 26 thus locking the plate 20 in position. Fine manual tuning. Fig. 3 shows a modification in which a clutch plate 33 is spring biased against the bracket 16. Fine manual tuning is available by means of a knob 34 and a friction wheel 31. When any push button is operated a cam surface 19b at the end of the push-button rod 19 displaces a member 38 to the left to disengage the clutch. Specification 858,306 is referred to.
