    Abstract: A radiation convertor for use in neutron imaging detectors includes apparatus for conversion of energetic primary charged particles resulting from neutron capture into low energy (eV) secondary electrons. The radiation convertor includes efficient secondary electron emitters, which are preferably alkali halide secondary electron emitters which are preferably CsI secondary electron emitters. The radiation convertor preferably combines at least one layer of Gd and an efficient secondary electron emitter preferably of alkali halide, preferably CsI. The layer of Gd may be at least one metallic layer selected from natural Gd and 157 Gd and this is used in combination with a layer of CsI. The neutron convertor may be alternatively 6Li, LiH or 177 Hf used in combination with an efficient secondary electron emitter, preferably alkali halide emitter, preferably CsI. A neutron imaging detector of the invention may combine a secondary emission composite neutron convertor including efficient secondary electron emitters and an electron multiplier which is sensitive to low energy secondary electrons emitted from the composite neutron convertor. In such a neutron imaging detector combination, the electron multiplier may be a vacuum micro channel plate (MCP) multiplier, a vacuum microsphere plate (MSP), or any other vacuum electron multiplier and imaging device, or a gaseous electron imaging multiplier, preferably a gaseous electron multiplier in which the secondary electron multiplication starts at their emission location from the convertor, preferably a low-pressure multistage electron multiplier.

    Abstract: Water softening is achieved by a combination of electrodialysis and calcium carbonate precipitation. The hard feed water or alternatively recycled soft water is rendered alkaline and is then subjected to a treatment by which precipitation of calcium carbonate is induced. One way of bringing about such precipitation consists in passing the alkaline water across a cake of calcium carbonate crystals having a size not exceeding 100 microns, deposited on a filter (43) and being in an at least fifty fold excess over the amount of calcium carbonate to be precipitated.
