Abstract: 907,644. Purifying water by freezing. CARRIER CORPORATION. Nov. 11, 1958, No. 36247/58. Class 29. Potable water is obtained from saline solutions such as sea water by freezing the solution to form a mixture of ice and concentrated solution, separating it, and washing it by potable water obtained by melting part of it. As shown, sea water is supplied by pipe 429 to a cylinder 405 containing a helix 407 and refrigerated by an evaporator jacket 409 forming part of a compression system. The ice and solution is supplied by pump 431 from the cylinder to separator column 414 where the ice separates by gravity, the solution leaving through pipe 433. Pump 431 is controlled by regulator 420 responsive to the liquid level in the column. Ice emerging from the top of the column is supplied by slinger 421 into a trough 423 where it melts and whence the melt water flows to the condenser 443 of the compression system to cool it. The heated water from the condenser flows through pipe 447 from which part flows through regulator 438 and pipe 437 to nozzles 425 above trough 423. This warm water melts the ice in the trough and also raises the temperature of the upper part of the column so that part of the rising ice melts and washes the remainder as it percolates through the ice. The rest of the potable water from pipe 447 and the solution from the column precool the entering sea water in exchanger 428.

Abstract: 1391713 Torsional pendulum RHONEPOULENC SA 3 Aug 1972 [4 Aug 1971] 36395/72 Heading G1A The torsional modulus of a material is measured at different temperatures. The material to be tested is impregnated into a braid of glass fibres 4, the angular position of which about an axis is monitored by means of a photo-electric system and an opaque element 7 secured to the braid, the element being in the path of light from the source to the detector of the photo-electric system and having an elongate recess therein the width of which as measured in a direction parallel to said axis varies regularly from one end to the other, so that more or less light falls on the detector in dependence on the angular position of the braid. The braid is suspended from arm 2 via support 3. At the lower end of the fibre bundle, the opaque element, a cylindrical member 7, is attached to a disc 6 attached to the bundle 4. The fibre is arranged to hang vertically by means of thread and counterweight 12. The cylinder 1 has a triangular recess of the form shown in Fig. 2. In operation, the fibre bundle is twisted through a certain angle by support 3, and released. Intensity variations sensed by the detector, as parallel light from the source/lens combination 13, 15 is repetitively modulated by the oscillating member 7, are recorded after amplification on a chart recorder. The temperature of the test sample is controlled by a thermal chamber or a cryostat 5. Modifications. In the arrangement of Figs. 1, 2, the signal is proportional to the angle of rotation, in which case a logarithmic amplifier is used in the detector circuit. However, the recess in member 7 may be designed to give a logarithmic detector response directly. Instead of a vertical oscillating system, a suitably mounted horizontal oscillating system may be used. Instead of a cylindrical member 7, a cone or truncated cone may be used, or a plane screen. The recess can be formed of transparent or translucent material e.g. of glass, polymethyl methacrylate.
