Title: Improvements in methods of coating seeds
IPC: A01C1/06
Filed: 1959-07-29
Abstract: 881,552. Seed pellets. COMPAGNIE NORDAFRICAINE DE L'HYPERPHOSPHATE RENO. July 29, 1959 [Aug. 9, 1958], No. 26062/59. Class 58. To assist germination of seeds such as wheat, rice and maize, they are wetted with water or an aqueous wetting solution and coated with a powdered fertilizer, e.g. whose particles have passed through a screen having 80 to 100 meshes per square inch, to form pellets, which are then sprayed with concentrated sulphuric acid or ammonia to initiate drying by the heat developed. The fertilizer may contain natural or artificial phosphates or nitrogen and potash. Diatomaceous earth or kieselguhr may be mixed with the fertilizer. The amount of fertilizer coated on the seeds may be between three and seven times their weight. Between 3 and 5% of sulphuric acid, based on the weight of the pellets, may be used. The pellets may be given an additional coating of a finely powdered fertilizer, e.g. a superphosphate fertilizer, whose particles have passed through a screen having 300 meshes per square inch. A dye identifying the kind of seed may be incorporated in this coating. Alternatively, the pellets may be sprayed with an aqueous solution of sodium silicate. For example, seeds from a shoot 8, water from one or more sprinklers 10 and powdered fertilizer from a spout 13 are fed into the central compartment 1 of the rotating inclined tray of a granulator. The central compartment is surrounded by two annular concentric compartments 2 and 3. The powdered fertilizer sticks to the wetted seeds and forms a coating around each to produce pellets. These overflow into compartment 2 wherein they are sprinkled with concentrated sulphuric acid from one or more sprinklers 14. The pellets overflow into compartment 3, in which they are coated with finely powdered fertilizer supplied through a conduit 15, and then overflow into a shoot 16 or, alternatively, a conveyer belt.

Title: Improvements in or relating to communications system
IPC: G02F1/01
Filed: 1963-07-04
Abstract: 1,038,408. Light modulation. WESTINGHOUSE ELECTRIC CORPORATION. July 4, 1963 [July 9, 1962], No. 26575/63. Heading H4F. [Also in Division G1] An optical communication system (utilizing the Zeeman or Stark effects) comprises a transmitter 20 (Fig. 1) having an energy source 25, with a transmission frequency in the infra-red, visible or ultra-violet regions of the electromagnetic spectrum, the source being frequencymodulated with an intelligence signal, and a receiver 40, having an absorption cell 55, which is arranged to demodulate the frequencymodulated energy 33 from the transmitter to convert it into amplitude-modulated energy 27, and a transducer 57, to provide an electrical output signal corresponding to the intelligence signal. As shown in Fig. 1, the frequency modulator 22 consists of an electromagnet 24 having a winding 28 to which is applied a steady D.C. voltage to produce Zeeman splitting (Fig. 3, not shown) in the spectral source 25, which comprises a mercury or sodium gas discharge tube excited by microwaves. An A.C. intelligence signal is applied to the winding 34 to produce a frequency variation 26a, 27a on the spectral lines produced in the Zeeman splitting (Fig. 3 c, d). The frequency-modulated light is directed, for transmission, by a lens 32 and 16 collected in the receiver by a lens system 51, 53, which also filters out undesirable radiations, and directs the remaining energy into the absorption cell 55. The cell contains atoms of the same nature as the source and is located within the D.C. field of electromagnet 43, so that light entering the cell is subject to the inverse Zeeman effect. All the light from the lens system is thus absorbed by the cell except for the signal variations, which are converted into amplitudemodulated energy 27 which is, in turn, converted by a photo-multiplier 57 into an electrical signal which may be amplified at 59. In an alternative receiver to cancel out random noise &c. (Fig. 10, not shown), the light beam 27 is sampled before it enters the absorption cell and the sample fed direct to a photomultiplier, the output of which is fed to the same amplifier as the intelligence signal; the output of this amplifier representing the ratio of the signals from the sample photomultiplier and the intelligence signal photomultiplier. Other embodiments are referred to (Figs. 8 and 9, not shown), in which the Stark effect is used, employing an electric, instead of a magnetic field.
