Patent NL-2032495-A (NL)
Title: Coated controlled-release fertilizer and preparation method thereof
Inventor: XIANGZHONG ZENG
IPC: C05G5/30
Filed: 2022-07-14
Abstract: Disclosed is a coated controlled—release fertilizer, including inner fertilizer core granules and, outer‘ high—molecular coating materials, wherein the high—molecular coating material is nano calcium. carbonate modified, waterborne polyacrylate emulsion. In the present invention, the nano calcium carbonate modified waterborne polyacrylate emulsion is used as the main body of the polymer coating, and, thus the controlled—release performance of the fertilizer is obviously improved. It is proved by comparative tests that under the condition of the same amounts of the coating material and fertilizer core granules as well as the same preparation process, compared with the fertilizer with the coating material of unmodified waterborne polyacrylate, the slow—release fertilizer with the improved coating material of nano calcium carbonate modified waterborne polyacrylate has a lower, smoother and more uniform cumulative release rate, and the release period can be extended to about 1.9 times, so that the nutrient requirements of crops can be satisfied.

Patent NL-8203013-A (NL)
IPC: G01N21/21
Filed: 1982-07-28
Abstract: Method and apparatus for determining the saturation temperature of a solution. In an optical measurement vessel, the temperature of a sample of the solution is gradually decreased until crystals are formed and subsequently gradually increased until the crystals dissolve. The temperature is measured continuously and the formation and dissolving of the crystals is detected optically by means of a beam of polarised light which is transmitted through the measuring vessel, and passed through an analyzer the direction of polarisation of which is normal to that of the beam of light, and detected by a photodetector behind the analysator. Only when a small amount of optically active crystals is present in the solution, in which the direction of polarisation of the light is rotated, the photodetector measures a certain light intensity. The moment the last crystals, upon heating, dissolve is detected by the drop of the measured light intensity to a minimum value. The temperature of the solution at that moment is the saturation temperature of the solution. 
<??>Preferably the beam of polarized light is generated by means of a laser. For monitoring the transmitted beam, a beam splitter is preferably mounted in front of the analyzer, which casts part of the transmitted light onto a second photodetector.
