Title: Process and apparatus for crystallisation
IPC: B01D9/00
Filed: 1925-08-11
Abstract: 261,085. Marks, E. C. R., (Grasselli Chemical Co.). Aug. 11, 1925. Crystallizing. - In producing crystals of substantially uniform size, a solution is circulated from a pipe 6 upwards through a suspension of crystals in a vessel which is either conical and has an angle below 60‹, or is formed of successively wider cylindrical portions 2, 3, 4. Large crystals fall through the narrow part 2 and are removed by a pipe 7. Seed crystals are formed in the solution by supplying a supersaturated solution by a pipe 12. The solution is discharged at the upper end 4 and passes over a heating-device 3 to dissolve small crystals, and through a pipe 8 to a vessel 9 in which it may be evaporated or heated, and to which fresh concentrated or supersaturated solution is added by a pipe 10 prior to return to the pipe 6. The walls of the crystallizing vessel may be insulated, cooled, or may be warmed to prevent the rapid cooling. Crystals may be separated at the base of each of the sections in order to obtain more than one size of crystal product.

Abstract: 358,112. Variable - speed generator systems. STONE & CO., Ltd., J., Deptford, London, and HONEY, A. E., 31, Seymour Gardens, Ilford, Essex. July 5, 1930, No. 20431. [Classes 35 and 38 (iv).] Indicators, applications of.-A generator 3 driven by a belt from a vehicle axle is controlled at lower train speeds by automatic field regulation to cause successive reductions in output and at higher train speeds the output is limited by slipping of the belt, thus deferring belt slippage to a comparatively high train speed and permitting a low cut-in speed. The shunt field winding 5 is in series with resistances 6, 7, 8 which are short-circuited at two speeds and cut into the field circuit in succession by current-responsive coils 12, 13, 14 in the output circuit. To meet the case of rolling stock which may form part of slow or fast trains a handoperated switch 26 can be used to short circuit all the field resistance when the vehicle is in slow service. This switch may be combined with an output indicator, such as that described in Specification 183,703, [Class 35, Dynamo-electric generators &c.], the handle of the switch constituting the level device to be observed when adjusting the belt tension for fast or slow working.

Filed: 1927-08-05
Abstract: 288,077. Anderson, W. H. Aug. 5, 1927. Walls.-Caissons and the like are sunk into the ground by exhausting air from the interior of the structure, thus causing the surrounding air or water to rush into the interior under the bottom edge to loosen the supporting ground and causing the structure to sink under its weight together with the effective downward pressure of the atmosphere, supplemented by other loading if desired. As shown in plan, the structure 1 to be sunk may be divided into compartments 2 each communicating through a valve 5<1> with a. pipe 6 leading to a suction apparatus. A detachable cover 4 having an air inlet valve 7 is provided to each compartment. When the structure has been partially sunk, air is admitted to the interior of the compartments and the covers removed to permit the removal of the loosened soil, and the process is repeated a further step.

In a combine-harvester with a tiltable grain-tank 13, means are provided for bodily displacing the tank on the harvester body, the discharge aperture being located in the wall 16 of the tank facing the direction from which the displacement is effected. As shown, the tank is mounted on rollers 14 running on rails 11 which have a stop 12 at the outer end. The tank is displaced by a pivoted hydraulic ram 27 and is supported on each side by a bell-crank 22, 23 pivoted at 21 on the harvesterbody and having one arm 22 bent beneath the tank to carry a roller 24 and the other engageable by a stop 25 on the tank. When the rollers 14 reach the stops 12, the stops 25 engage the lever-arms 23, and further movement of the ram causes the tank to tilt about the rollers 14. A pivoted shoot 19 is mounted adjacent to the discharge aperture and can be lowered for delivery of grain. In a modification, Fig. 4, (not shown) the rollers, rails and bell-cranks are replaced by pairs of levers, the rearmost being longer, so that the tank is tilted simultaneously with its traversing movement.

A pressure - recording instrument, particularly for engine indicators, comprises a resilient diaphragm 3 to one side of which the pressure variations are communicated and having on its other side a chamber containing a liquid 8 and an elongated small cross-section piston 11 protruding into the liquid and reciprocable in and out of the chamber, the piston 11 or an extension 17 carrying a marker 13 for recording the movement of the piston in response to the variations in pressure. Because of the relatively large area of the diaphragm and small cross-section of the piston magnification of the diaphragm movement occurs at the piston. A perforated backing-plate may be provided on the pressure-remote side of the diaphragm to guard against excessive pressure movements. As shown, the pressure is communicated to the one side of the diaphragm by a plurality of bores 5. In a further embodiment, the pressure is communicated to the diaphragm by a piston in contact with the pressure and provided with a spring. By adding a second resilient diaphragm having different stiffness the response range may be varied. A filling opening in the wall of the chamber, provided with a plunger, may be used to vary the datum of the recorder and also to compensate for temperature fluctuations.
