Title: Method of cyclohexylamine regeneration from salts' aqueous solutions on base of 2-substituted benzothiazole from 2-substituted benzothiazole
Inventor: KACANI STANISLAV ING CSC
IPC: C07D277/80
Filed: 1987-11-30
Abstract: The solution concerns a method of regeneration of cyclohexylamine from water solutions of salts based on 2-substituted benzothiazole during production of N-cyclohexylbenzothiazolyl-2-sulfenamide from raw 2-mercaptobenzothiazole and sodium hypochlorite in surplus of cyclohexylamine. After separation of solid fraction and separation of the filtrate phases 1.4 to 5.0 weight parts of sodium hydroxide is added in the form of water solution per 100 weight parts of organic phase before entrance in atmospheric distillation. This results in releasing of cyclohexylamine from ionic bond on benzothiazolyl-2-sulfonic acid. The obtained distillate containing less then 1 percent by weight of benzothiazole is returned to the new synthesis of N-cyclohexylbenzothiazolyl-2-sulfenamide and the product from distillation columns is used as a secondary raw material.The solution can be used in chemical industry.

Inventor: KARPF HELLFRIED
IPC: G01N21/77
Filed: 1987-04-22
Granted: 1994-03-21
Abstract: Because of the size of the devices for the excitation or measurement of light, conventional sensor elements for optical determination of the concentration of substances in gaseous and liquid probes, which have an indicator layer with at least one indicator substance are only conditionally suitable for microanalysis instruments, or cannot be produced simply by mass production. To circumvent these disadvantages, it is proposed that at least one photosensitive element (3) and its electrical contact are integrated in a planar arrangement on the carrier layer (1), and that the indicator substance (7, 7') of the indicator layer (6), which is excited by the exciting radiation (11) is in optical contact with the photosensitive elements (3).

An apparatus for the treatment of meat-producing animals comprises drinking troughs 1, a main water pipe 9 which discharges into a water tank 3 through a float valve 15 and also feeds the mixing tank 2 via a pipe 4 and hand valve 11. Liquid sugar stored in tank 12, is pumped into tank 2 and mixed with water in amounts measured by meter 6. The tank 3 supplies the troughs 1 with water through pipe 18, manifold 19 and branch pipes 20, the flow being controlled by solenoid valves 21 and float valves 23. The mixing tank 2 supplies water and liquid sugar mixture to the troughs 1 through a similar system as shown. In operation, predetermined volumes of liquid sugar and water mixture are fed to the troughs 1 followed after a predetermined time by flushing water from tank 3 to prevent clogging. Recirculation of the liquid sugar is achieved through pipe 7 connected to pipe 4. Handvalves 8 and 14 control recirculation and supply respectively of the liquid sugar. The solenoid valves 21, 27 are controlled from panels 28.

Title: Grid-based method for analyzing and diagnosing a spatiotemporal pattern of chemical fertilizer application in farmland
Inventor: WANG LAIGANG
IPC: G06K/
Filed: 2023-05-24
Granted: 2023-12-01
Abstract: The invention provides a grid-based farmland fertilizer application amount space-time pattern analysis and diagnosis method. The method couples the county unit data in time series on chemical fertilizer application with county-level administrative division data in the region using GIS technology. Spatial interpolation is used to interpolate the coupled chemical fertilizer application data, and the interpolated data is gridded using a reclustering method. Soil organic matter data is also gridded using GIS technology. The spatiotemporal pattern of agricultural fertilizer application is analyzed based on the gridded data on chemical fertilizer application. The threshold for chemical fertilizer application in each grid is determined based on the gridded data on soil organic matter. Chemical fertilizer application diagnosis is then implemented based on the threshold for agricultural fertilizer application in each grid. The present invention considers the spatial correlation of chemical fertilizer application, and the grid scale achieves a more targeted spatiotemporal pattern analysis and diagnosis of chemical fertilizer application. This method improves work efficiency and effectively improves the accuracy and precision of preventing and controlling chemical fertilizer pollution.

Filed: 1996-06-28
Abstract: The invention relates to a process for the preparation of a pure and solid, sulfate- and hydroxide-based ferric compound such as ferric hydroxysulfate or sodium jarosite, the process comprising the following procedures: a) a sulfate- and/or chloride-based ferric salt is prepared, b) an acidic aqueous solution is prepared which comprises either sulfate ions and ferric ions or sulfate, chloride and ferric ions, c) the acidic aqueous solution is maintained for 2-12 h at a temperature of 60-220  DEG C for the production of a solid, sulfate- and hydroxide-based ferric compound, such as ferric hydroxysulfate or sodium jarosite, by hydrolysis, and d) the pure and solid sulfate- and hydroxide-based ferric compound, such as ferric hydroxysulfate or sodium jarosite, is separated from the acidic aqueous solution. The processes for the preparation of ferric hydroxysulfate and sodium jarosite differ substantially only in that in the preparation of sodium jarosite an acid aqueous solution is prepared which, in addition to the either sulfate and ferric ions or sulfate, chloride and ferric ions, also contains a water-soluble sodium compound, in which case sodium jarosite is formed instead of ferric hydroxysulfate in the hydrolysis of point c) of the process.
