Title: Improved method and apparatus for separating the components in brine
IPC: C01D3/14
Filed: 1966-02-25
Abstract: 1,142,901. Potassium magnesium chloride; potassium chloride; magnesium chloride; magnesium sulphate. A. F. NYLANDER. 25 Feb., 1966 [26 Feb., 1965], No. 8382/66. Heading C1A. The potassium in a brine also containing sulphate ions is separated therefrom by adding MgCl 2  to the brine in an amount such that (a) the solubility of the sulphate component is not exceeded and it remains in the resulting solution, and (b) this resulting solution, on evaporation at a rate sufficiently rapid to avoid achieving equilibrium between the salt deposited and the evaporating solution, deposits potassium as carnallite KCl.MgCl 2 .6H 2 O at that point where potassium is no longer able to remain in solution, and subjecting the solution to such evaporation. MgCl 2  may be added in an amount such that the solution contains 78 mole per cent of Mg calculated on the basis of the magnesium, potassium and sulphate ions present in the solution. The MgCl 2  may be added as a bittern obtained from the evaporation of brine to a density of between 1À33 and 1À37 and it may be added to a feed brine from which substantial amounts of NaCl have been removed, said feed brine having a density less than 1À32 being just below potassium saturation, the densities being measured at 35‹ C., to form a brine saturated as to potassium and unsaturated as to sulphate. The mother liquor from the crystallization of carnallite may be further evaporated to crystallize hydrated magnesium sulphate, removing these crystals and using this mother liquor, which in a process using solar evaporation of a marine brine is an invariant bittern, as the recycle liquor in the process. This bittern may be added to the brine in a series of increments if so desired. If necessary, or desirable, any calcium salts may be removed from the initial brine by evaporation before first precipitating part of the sodium chloride content and then adding MgCl 2  to the resulting liquor. Some of the above mentioned invariant bittern may be evaporated to crystallize bischofite, MgCl 2 6H 2 O, and these crystals may be used alone as the recycle, or utilized as a slurry in brine. Particular concentrations of Mg, K and SO 4  in the brine are given in the Specification. An arrangement of salt pans for the solar evaporation of brine is given in the Specification. The carnallite obtained may be treated to obtain KCl and the residue may be recycled.

Filed: 1946-03-19
Abstract: 609,864. Hydraulic brakes. GUNDERSON, R. R. March 19, 1946, No. 8477. [Class 103 (i)] A hydraulic brake system includes a cylinder A connected by a pipe N to a pedal-operated master cylinder and containing a piston D which is operable to supply liquid to the wheel cylinders through a pipe O by a flexible dia. phragm F forming a wall of a vacuum chamber mounted on the end of the cylinder. The piston and diaphragm are connected by a tubular piston-rod E containing a piston L which acts through a spring L<SP>3</SP> on a rod M connected to a valve member H<SP>1</SP> carried by a flexible diaphragm' H forming the opposite wall of the chamber, the space to the right of the diaphragm being in communication with atmosphere through a perforated diaphragm G<SP>1</SP>, an air filter K and an opening K2. A suction conduit I is normally closed by a valve member J urged to the left by a spring J<SP>1</SP>, and the member H<SP>1</SP> is normally held to the left by a spring H<SP>2</SP> to maintain the vacuum chamber in communication with atmosphere. When the master cylinder is operated, the piston L is moved to the right and the member H<SP>1</SP> first seats on a flange J<SP>2</SP> of the valve J and then opens the valve to cause operation of the piston D. The difference in the pressures acting on opposite sides of the diaphragm H then moves the rod M to the left to compress the spring L<SP>3</SP> and allow the valve to reclose, this action being assisted by the reduction in the pressure acting on the piston L as the piston D moves to the right. The vacuum established in the chamber is thus proportional to the amount of depression of the master cylinder pedal, and the operator is able to " feel " the brake pressure applied. The cylinder A is formed with byepass grooves A<SP>3</SP> so that the initial movement of the shoes to bring them in contact with the drum is effected by pressure-liquid supplied directly from the master cylinder. These grooves also prevent airlocks in the system.
