Title: Process and apparatus for the manufacture of granular fertilisers
IPC: C05B1/02
Filed: 1980-05-02
Abstract: Granular fertilisers are manufactured by reacting a hot aqueous solution of ammonium nitrate and/or urea, and optionally ammonium phosphate, which solution usually contains only a little water, with at least one powdered substance containing one or more fertilising elements, such as simple or concentrated superphosphates, monoammonium and diammonium phosphates and other binary compounds containing phosphorus and nitrogen, potassium chloride or sulphate or naturally occurring phosphates, so as to form a slurry, and converting this slurry to granules by mixing it with a pulverulent fertiliser, which may comprise recycled material originating in the process, for example during grading of the product.

Title: A Method of and Apparatus for Varying the Load on an A.C. Generator
IPC: G05F1/67
Filed: 1981-07-09
Abstract: The variation of the load on a wind-driven A.C. generator (16) in accordance with a predetermined law which relates the load to the speed of rotation, is achieved by detecting the period of each half cycle with the aid of a timing unit (10), calculating the percentage conduction required in each half cycle in accordance with the predetermined mathematical law, and using the calculated result to gate a pair of thyristors (12, 14) to conduct for said calculated percentage in alternate half cycles so as to pass a unidirectional current to said load. By variation of conduction during each half cycle the effective resistance of the load can be matched to the voltage output of the A.C. generator over a wide range of speeds. Not only can the efficiency of the system be increased, but the windmill is prevented from being stalled in light breezes. <IMAGE>

Filed: 1981-12-30
Abstract: A dual orbit sprayer assembly particularly for use in continuous coaters includes a pair of rods 20 rotatable about a central shaft 16, thereby defining a primary orbit. At the end of each rod 20 is a pair of arms 30 rotatable about their own individual shafts 26, such arms having spray nozzles 36 at the ends thereof. Rotation of the arms 30 causes the nozzles to pass about secondary orbits having their centers maintained upon the primary orbit.

Patent GB-2127619-A (GB)
Title: Infrared detectors
Inventor: WHITE ANTHONY MICHAEL
IPC: H01L31/11
Filed: 1983-09-15
Abstract: A detector (Fig. 1) in which a barrier region (11) is interposed in the current path between the emitter (13) and collector (9) of the detector. This region (11) is of a material having a valence band edge approximately level to that of the emitter material and an appreciably wider band gap (Fig. 2). It thus serves to impede majority carrier current flow and as a consequence device resistance is high. When the detector is biassed, the pedestal contribution to detector signal is low. The collector (9) may be of semiconductor material of the same majority carrier type as the emitter material; or may be of opposite type but dopant enriched; or it may be a Schottky metal contact. In one variant of the detector, the emitter (13) and collector (9) are located on opposite sides of the barrier (11) and are of different band- gap materials. The infrared band response of this detector can be changed by reversing bias polarity. In another variant of the detector (Fig. 4, not shown) the emitter (23) is in strip form and has a pair of bias contacts. The barrier (31) and collector (33) are located on the strip at a position between these contacts and provide a high resistance read-out structure (29). In one further variant of the detector (Fig. 6, not shown) the emitter (45), the collector (45), together with additional emitter- collector regions (45), are formed from a single layer of photosensitive material on one side of the barrier (43) and provide a high resistance, series connected, multi-element, structure. <IMAGE>
