Title: Phosphatic fertilizer materials
Inventor: BRADLEY JOHN KENNETH
IPC: C05B11/06
Filed: 1957-01-10
Abstract: A process for the production of complex fertilizers comprises reacting phosphate rock with the liquid product resulting from the reaction, at over 80 DEG C., of potassium chloride and nitric acid, the nitric acid being in excess of 4 mols nitric acid per 3 mols of potassium chloride, so as to give a product containing free nitric acid, when the formed nitrosyl chloride and chlorine have been removed.  The chloride-acid reaction takes place, preferably in the range 100-120 DEG C using concentrated nitric acid and any form of potassium chloride.  Sulphuric and phosphoric acids may be added to the liquid product along with the rock if required, and the final product may be neutralized with ammonia, or potassium hydroxide or carbonate.  Other fertilizer constitutents may be added to the final product and granulated.  The process permits the production of NPK fertilizers having widely varying ratios of elements according to the varying quantities of reactants used in the process.  The nitrosyl chloride which is removed from the reaction between the potassium chloride and nitric acid may be oxidised to form chlorine and oxides of nitrogen which may be rejected as such, or as nitric acid, to the reaction system.  Specification 876,565 is referred to.

Title: Scanning apparatus
Inventor: NARAYAN BADHRI
IPC: G02B27/00
Filed: 1992-05-21
Abstract: A scanner including a source of coherent light, a radial hologon, a f theta  lens and a target. Between the light source and the hologon there are means for forming light from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross-sectional shape of the beam radial of the axis of rotation of the hologon. Prismatic means are provided between the hologon and the lens means for so modifying the cross-sectional shape of the beam that the spot at the target station has a selected shape and orientation. This allows the shape, orientation and size of the beam on the hologon to be optimum for duty cycle of the hologon and for spot size on the target. The prismatic means allows the spot shape and orientation on target to be optimized. The prismatic means tends to introduce undesirable bow into the scan line, therefore the wavelength of the light and the grating factor (n  lambda )/d of the hologon are selected to produce an approximately equivalent opposite bow.
