Title: Process for forming ice crystals in aqueous solutions
IPC: C01B11/06
Filed: 1962-08-13
Abstract: 1,002,600. Concentrating or purifying solutions by freezing. LUMMUS CO. Aug. 13, 1962 [Aug. 11, 1961], No. 30939/62. Heading F4H. Ice crystals are formed in an aqueous solution by first contacting the solution with a hydrate forming substance to form a hydrate in the solution, then reducing the temperature of the hydrate to the fusion temperature of water in the aqueous solution and decomposing the hydrate while simultaneously forming ice crystals. As shown, sea water from a line 10 is pumped through pre-coolers 14, 16 to a vessel 18 where it is directly contacted with liquid propane from line 20 to form a hydrate, the vessel 18 being cooled by indirect heat exchange with an ice slurry from line 22. Hydrate-brine mixture from vessel 18 then passes through line 26 to a vessel 30 which is maintained at a low pressure and in which the hydrate decomposes and ice crystals are formed, propane vapour released during the decomposition being withdrawn through line 32 under the control of a valve 34 and supplied to a compressor 54. Icebrine slurry is passed through line 36 to a centrifuge 38 where the ice is washed with fresh water from a line 40, then separated and passed through line 44, a repulper 46 in which controlled amounts of product water are added to the slurry and line 22 to vessel 18 where it provides cooling during the hydrate formation and is melted. Part of the resultant water passing through line 24 is supplied to the centrifuge through line 40 and part to a condenser 50 where it directly contacts and partially condenses propane vapour from the compressor 54. The water then leaves the condenser through line 52 and is used in precooler 14 before leaving the process as product water. Liquid propane from condenser 50 passes through line 56 to line 20 while propane vapour passes through line 58 to a second compressor 62, condenser 66 and flash cooler 70, the liquid propane from the latter also being passed to line 20 for use in vessel 18. Propane vapour from the flash cooler is recycled through line 60 to the inlet of compressor 62. Brine leaving the centrifuge 38 through line 42 is used in precoolers 14 and 16 before passing to waste. Cooling for the decomposition of the hydrate may be provided either in the vessel 30 or in line 26 by indirect contact with a refrigerant instead of reducing the pressure in vessel 30. The process may also be used to concentrate fruit juices or waste sulphite liquors and the function of the vessels 18 and 30 may be performed in a single jacketed vessel which is provided with agitators and in which the pressure is reduced after formation of the hydrate.

Abstract: 856,336. Swaging machines. APPEL PROCESS Ltd. Sept. 16, 1959 [March 9, 1959], No. 31540/59. Class 83 (4). [Also in Group XXIX] Hydraulic means for causing alternate incremental forward movements and blockings of a member, such as a workpiece W in a swaging machine, comprises a cylinder 75 having a piston 90, the forward face of which is connected to the member and is smaller in exposed area than the rear face, a quick-opening and closing valve V9 in a forward-movement pressure line 179, 183 connected to a pressure source, and a forward bleeder valve V14A which is located in the forward movement pressure line between the valve V9 and the rear part A of the cylinder and connected by a bleeder line 186 to the forward end B of the cylinder, the bleeder valve automatically opening when the valve V9 connects the source to the rear end of the cylinder and automatically closing when the valve V9 closes to prevent bleeding of the rear part of the cylinder and rearward movement of the piston and member. The valve V9 is cyclically operated to feed the workpiece W between the dies 21 of the machine by electrically-operated means driven from shafts 406 having eccentrics which reciprocate rods 404 carrying cams 402 engaging the ends of the die movers 22 of the machine; wedges 23, movable by piston-and-cylinder devices, permit the position of the stroke of the die movers to be varied. The liquid-pressure to the rear end A of the cylinder 75 is supplied through a valve V8 connected to the forward movement pressure line 179. Pressure in the line 179 is transmitted by a line 179<1> to one end of the spool of a valve V11 to close lines 178, 185 which are operative when the piston is moved rearwardly. When the valve V9 is open the liquid-pressure opens valve V14A and piston 90 moves forwardly to feed the workpiece between the dies, liquid in the forward end B of the cylinder passing through line 186 and valve V14A to the rear of the piston. When the valve V9 is closed, valve V14A closes to block the flow from the rear end A of the cylinder to prevent rearward movement of the piston while the dies act on the workpiece. The piston 80 can be reversed by operating the valve V8 to disconnect the pressure source from line 179, the decrease in pressure in line 179<1> permitting the spool of valve V11 to move to the right and the source to be connected to the line 178 to move the piston rearwardly, liquid from the rear end of the cylinder passing through line 185, valve VI and a valve V13 to exhaust. Specification 797,518 is referred to.
