Title: Improvements in or relating to a method for ageing solutions of colloidal material from which artificial filaments and like materials may be spun and apparatus therefor
IPC: D01D1/09
Filed: 1944-04-28
Abstract: Solutions of colloidal material from which artificial filaments and like materials may be spun, such as solutions of viscose or other aqueous alkaline cellulosic solutions or alkaline solutions of proteins, are aged to a predetermined viscosity for a fixed temperature by passing a stream of the solution through a zone heated by means viscostatically controlled by variations in viscosity from a fixed value in a continuously and progressively renewed fraction of the resulting aged solution brought to a fixed lower temperature. The process is applicable to solutions which become more viscous or less viscous on ageing and the aged solution is brought to and delivered at a temperature at which any alteration in viscosity proceeds comparatively slowly.  The whole or part of the aged solution is passed through a zone where variations in viscosity of the cooled solution are detected and actuate responsive means through which the viscostatic control of the ageing temperature is exercised. Referring to Fig. 1, a solution is withdrawn from reservoir 1 and pumped through coil 3 wherein it is aged.  The coil 3 immersed in vessel 4 is heated by water in which a heater 49 is immersed.  On leaving coil 3, the aged solution passes into vessel 32 which is enclosed in a cooling jacket 48 and in which a stirrer 33 is caused to rotate at constant speed.  The solution in vessel 32 is brought to a fixed lower temperature and variations in its viscosity from a fixed value cause variations in the energy required to rotate the stirrer 33 at constant speed, which in turn operate relays 43, 44 controlling the heat input to heater 49 and the warm water input to the vessel 4.  The solution passes <PICT:0579089/IV/1> <PICT:0579089/IV/2> from vessel 32 to spinneret 52 from which it is extruded into filaments.  In a modification (Fig. 2), aged solution passes from ageing coil 3 through a pipe 9 which has a constricted portion 10 surrounded by cooling jacket 29.  Variations in the viscosity of the solution from a fixed value cause variations in the pressure differential of the solution across the constriction 10, which in turn actuate pistons 12, 121, piston-rods 15, 151 being connected by a cross-piece 16 which is pivoted about spindle 17. Another piston 18 actuated by movement of the cross-piece 16 is ported to establish connection between pipe 22 and either a hot-water feed pipe 20 or a cold-water feed pipe 21.  Hot or cold water can thus be fed to vessel 4 according as the differential pressure increases or decreases.

Title: Systems for liquid recovery by vapour condensation
IPC: C02F1/08
Filed: 1968-02-20
Abstract: 1,212,252. Surface condensers. SALINE WATER CONVERSION CORP. 20 Feb., 1968 [21 Feb., 1967], No. 8118/68. Heading F2S. [Also in Division B1] A surface condenser intended for use in a desalination plant comprises a chamber through which horizontal tubes extend and on the outside of which tubes a vapour is condensed by a coolant flowing through the tubes, said tubes occupying a volume in the range of 2 to 5% of the total volume of said chamber, and being so arranged that condensate from any one tube falls into a collecting trough thereunder without contacting any other tube. In Fig. 3, a pool 54 of saline water is maintained in a housing 52 and further saline water at a slightly higher pressure is injected into the pool via a tube 50. Some of the injected water flashes into steam on the surface of the pool, whereafter condensation takes place on the surface of the coolant tubes 60a, 60b, 60c, the condensate being collected in troughs 58. Fig. 5 (and Fig. 6) shows part of a multistage flash evaporator and surface condenser, two stages being shown. Each condenser stage includes tubes 112 or 112<SP>1</SP> grouped in sheet metal condensate collecting troughs 104 or 104<SP>1</SP>. Above the open end of each trough is a canopy 110 or 110<SP>1</SP> which prevents impingement on the condenser tubes of unevaporated saline water droplets from the preceding stage. These droplets are diverted by the canopy on to the outer surface of the associated trough 104 or 104<SP>1</SP> whence they flow through passageways 106 or 106<SP>1</SP> between adjacent troughs to a collector tray 120 or 120<SP>1</SP> therebeneath. From each tray are passages 122 or 122<SP>1</SP> packed with a permeable material and in which flash evaporation occurs, the resulting vapour passing to the next lower condenser stage of the system. A further form of combined flash evaporator and surface condenser is described (Fig. 1) in which the condenser tubes are in groups one above the other, separated by a drip deflector baffle (34). In another condenser arrangement described (Fig. 4) a cylindrical shell is divided by transverse partitions (72, 74) into a vapour inlet chamber in communication with two other chambers (78, 79) each containing a set of condenser tubes (80). This arrangement is apparently intended for comparing condenser tubes having different positional arrangements and surface characteristics; e.g. the tubes (80) in one chamber may be made of titanium whilst those in the other chamber may be of a cupro-nickel composition.
