Abstract: An electric fan assembly comprises a generally cylindrical cross-flow fan (10) a rear guider (14) and a stabilizer (12). The rear guider (14) has an downstream edge with respect to the direction of flow of an air current which is hingedly connected (18) with a pivotable plate (16). By the utilization pf the adherence effect of the air current to the pivotable plate (16), the direction of blow of the air current is controlled by pivoting the pivotable movement of the pivotable plate (16). This results in that a slight pivotal plate (16) is sufficient to bring about the deflection of the air current over a relatively large angle. The fan assembly may be employed in an air-conditioner in which case a relatively high air-conditioning efficiency can be appreciated.

Abstract: A carburettor (10) comprises an air passage (14) containing a hollow toroid (40) having nozzles therein from which fuel/water is injected into the air passage along the periphery thereof. Both the fuel and the water are fed from pumps and needle valves (50 and 52 on the one hand and 94 on the other hand) and respectively control fuel and water flow to the toroid (40). The position of one fuel control needle valve (50) is determined by the vacuum in the air passage and that of the other fuel control needle valve (52) by the setting of the butterfly valve (20). An overflow line (42) leads away excess fuel that cannot pass the fuel needle valves (50 and 52).

Abstract: In a coal gasification operation or similar conversion process carried out in the presence of an alkali metal-containing catalyst wherein solid particles containing alkali metal residues are produced, alkali metal constituents are recovered from the particles primarily in the form of water-soluble alkali metal sulphites and bisulphites by treating the particles with a solution of sulphurous acid. The aqueous solution containing water-soluble alkali metal sulphites and bisulphites is then separated from the treated particles, treated to remove soluble aluminium compounds, and then recycled to the gasification process where the alkali metal sulphites and bisulphites serve as at least a portion of the alkali metal constituents which comprise the alkali metal-containing catalyst.
