A snowboard has two bindings for two boots (21) with the bindings being arranged at a substantial angle to the longitudinal axis (45). Each binding includes a board plate (17) secured to the board (11) and a boot plate (21) which is fixedly connectable to the boot (31). Both plates (17, 21) are drawn into firm contact with one another by resilient tension means (24, 25, 26, 27) which are substanti...

Process for separating calcium and nitrogen from lithium. This process is characterised in that alumina is added to molten lithium so as to form aluminium nitride and calcium oxide, which are insoluble, and the said insoluble materials are separated off with heating to recover purified lithium. It finds its application in the production of lithium of a quality which is particularly suita...
