Abstract: 678,420. Air-cooling installations; refrigerating. SCHELP, H. R. Oct. 5, 1950 [Oct . 14, 1949], No. 24326/50. Classes 29 and 64(iii) In an air-conditioning system wherein the conditioned air is cooled and dehumidified in a heat-exchanger by working air travelling in a separate circuit, the working-air circuit includes an expansion device 1, followed by a zone 3, containing the heatexchanger 4, and through which the workink-air passes at sub-atmospheric pressure and reduced temperature and is saturated with moisture by a nozzle 7, the zone being terminated by a compressor 2 which ejects the working-air from the system along a duct 6. The expansion and compression devices can be of various types: in Fig. 1 the expansion device is a turbine 1 coaxial with a bladed compressor 2 driven by a motor 13. A fan 11, drawing air through the air-conditioning duct 12, is driven from the same shaft 10. In Fig. 2, the expansion device comprises a nozzle 15 at which the air expands adiabatically and the compressor consists of a jet pump 19. The working-air is drawn from the room 14 to which conditioned air is to be supplied, the latter being partially derived from the room along a duct 23 and partially from the atmosphere along a duct 24; a damper 25 regulates the proportions of air from these two sources. In further modifications the expansion devices comprises a Hilsch tube, employing the relative cooling effect at the centre of a whirling mass of air. The compressor may be common to several systems, each with its own expansion device and heat-exchanger. The spray-nozzles may precede and follow the expansion device and the rate of supply of liquid may be controlled in accordance with wet and dry bulb'thermometer readings in the working zone.

Title: Process for producing large sodium bicarbonate crystals
IPC: C01D7/38
Filed: 1957-07-31
Abstract: A process for the production of large crystals of sodium bicarbonate comprises carbonating a solution containing sodium carbonate, the alkalinity of the solution being maintained at 9.5 to 11.25 per cent by weight of sodium carbonate and containing 11 to 14.5 per cent by weight of sodium chloride, by contact with a gas stream containing 10 to 90 per cent by volume of CO2 at a rate of 0.12 to 2.4 cu.ft./min./cu.ft. of solution at a temperature of 45-100 DEG  C., the gas rate being increased as the concentration of CO2 in the gas stream is lowered.  In the preferred embodiment of the invention, the process is carried out in three stages, the conditions stated above only being applicable to the second stage.  In the first stage a solution of sodium carbonate containing 15-16 per cent of sodium chloride is contacted with a stream of gas containing CO2 until not more than 30 per cent of the sodium carbonate is converted into bicarbonate.  In stage two the alkalinity and sodium chloride content are adjusted to 10.6 per cent by weight of sodium carbonate and 12.5-13.5 per cent by weight respectively and the solution contacted with a gas stream at a rate of 0.4-1.2/cu.ft./min./cu.ft. of solution at a temperature of 55-60 DEG  C. until 64 per cent of the sodium carbonate has been converted into the bicarbonate.  The third stage consists in the addition of sodium chloride into the solution until the resulting solution contains 18 to 20 per cent by weight of sodium chloride and further contacting the solution with a gas stream containing at least 70 per cent by volume of carbon dioxide at a rate of 0.1 to 0.2 cu.ft./min./cu.ft. of solution to convert the remaining sodium carbonate to bicarbonate.
