Title: Improved manufacture of phosphoric acid
IPC: C01B25/20
Filed: 1932-10-28
Abstract: Phosphoric acid is obtained by injecting sufficient liquid water into the charge of a phosphorus-producing furnace or into the gases therefrom to cool the furnace or into the gases therefrom to cool the furnace gases to 600 DEG  C.  According to one example, the gases from a closed electric phosphorus furnace are cooled to about 600 DEG C. by the injection of water which evaporates, the phosphorus being oxidized.  According to a further example, water is introduced into a phosphorus producing shaft furnace at a level sufficiently high for the reaction displacing the phosphorus to be practically terminated. After separating the phosphoric acid the residual gases consisting of carbon monoxide, carbondioxide, hydrogen and nitrogen have a calorific value of 850 to 1000 calories per cubic metre.

Abstract: 787,569. Ventilating. ROBERTSON THAIN, Ltd. (Robertson Co., H. H:). Mardh 16, 1955, No. 30474/56. Divided out of 787,565. Class 137 In a ventilating system wherein air from different sources 70, 71 passes through a mixer 61 to selected floor cells 56, 57 from whence it is distributed to the building, the dampers 210, 214 controlling the admission from the conduits 70, 71 are automatically operated by a piston-and-cylinder mechanism 230 which is responsive to a thermostat 220. The thermostat may be selectively set so as to be responsive to one or other of two different sets of conditions for example winter and summer operation. In winter when hot air is being supplied from one source and cold by the other the thermostatically controlled mechanism 230 imparts opposed movements to the dampers i.e. one pair of dampers, e.g. 214, open as the other dampers 210 close; in summer when both conduits 70, 71 would be supplying cool air both pairs of dampers can be moved by the control into substantially open position. This enables the capacity of the cool air supply to be increased without increasing the size of the ducts. Specification 420,062 also is referred to.

In MHD apparatus comprising a conductive liquid, a source of gas or vapour, and an emulsifier for dispersing the gas or vapour in the conductive liquid to form an emulsion of bubbles of the gas or vapour in the conductive liquid, the liquid, in operation, flows transversely to a magnetic field in paths including successive emulsified and non-emulsified regions, 3 and 6 respectively, and there occurs simultaneously in at least one emulsified region of at least one liquid flow path, the interconversion of mechanical and electrical energy, the movement of the gas or vapour bubbles with a component of velocity transverse to the velocity of the liquid, and heat exchange between the gas or vapour bubbles and the conductive liquid. In the MHD generator shown, gas or vapour is introduced at emulsifiers 2 on the outer periphery of a vortex of liquid and flows in spiral paths to a separator 4, and the depth of the vortex increases progressively towards the centre to allow for expansion of the gas. Members 7 are inserted in the non-emulsified regions since a smaller volume is required in these regions, there being no gas or vapour preesnt. Electrodes E<11> and E<1>1 or E<1>2 serve for the removal of electric current and vanes 8, Fig. 3 (not shown) may be inserted in the non-emulsified zones to serve as intermediate electrodes and as guide vanes for the liquid. Instead of forming flat spirals, as shown, the gas flow paths may take the form of cylindrical or conical spirals. The apparatus may also serve as an MHD pump.
