A method for complex procesing of sea-water comprises the successive steps of mechanical filtration, calcium separation on modified zeolite, magnesium separation on weak-acid cation exchanger and processing of the resulting softened sea-water, regeneration of the modified zeolite and regeneration of the weak-acid cation exchanger. During the step of processing of the softened sea-water, its desalination it carried out so as to produce fresh water and simulatneously produce secondary brine having a concentration of salts at least as high as 100 g/l whereby the modified zeolite is regenerated. A plant for implemention of the method of complex processing of sea-water comprises a filter, two sorption columns for calcium separation connected in parallel with each other, a sorption unit for magnesium separation, a softened sea-water processing unit and a mixed concentrate processing unit.

A method of determining the quality of oriented polymeric materials, based on the effect of small-angle scattering, comprises the passage of a beam of monochromatic, polarized and collimated light through a given material, extracting the scattered reflections, converting them to a train of electric pulses, and determining the degree of orientation of the material using the pulse spacing. An apparatus for determining the quality of oriented polymeric materials comprises a source which produces monochromatic, polarized and collimated light passed through an oriented polymeric material, and a housing which accommodates an analyzer, a mask and a scattered reflection converting unit to convert the scattered reflections extracted by the mask to a train of electric pulses, which are arranged serially along the direction of the light beam after the material. The scattered reflection converting unit comprises a scattered light detector coupled to the recorder.

A filter for polymer melts and solutions comprises a casing having an inlet opening and an outlet opening. The casing accommodates a hollow mandrel supporting filter elements which are axially unmovable due to the provision of clamping flanges. Each element consists of a spacer plate located between filtering baffles, a sleeve having through radial passages communicating the inner space of the filter element with the inner space of the mandrel, the sleeve being mounted between the filtering baffles on the periphery of the mandrel, and a seal located between the filtering baffles on the periphery of the spacer plate. In addition, the casing accommodates auxiliary seals provided between the filter elements on the periphery of the mandrel and a spacer device arranged between the filter elements. The spacer device comprises auxiliary spacer plates each corresponding to the filtering surface of the filtering baffle. The filter is also provided with a washing device.
