Abstract: PROBLEM TO BE SOLVED: To provide a method for improving hydrolysis of cyanuric chloride to DCHT-Na under use of caustic soda solution so that the reaction is surely controllable even in industrial scale. SOLUTION: In this producing method, alkali metal hydroxide or alkali earth metal hydroxide in an amount of 1-2.5 equivalent based on 1 mol cyanuric chloride is charged in an aqueous solution or suspension into a vessel and cyanuric chloride is weighed and fed in the form of powder or aqueous suspension to the vessel while keeping pH value of the liquid in the range of 9.5-14 and cooling the liquid and when charging amount of the alkali metal hydroxide or alkaline earth metal hydroxide is stoichiometrically insufficient, residual amount of the above hydroxide including excessive amount up to 25% is weighed and fed during or after addition of cyanuric chloride in order to keep pH value of the liquid and the reaction is finished when the pH value does not substantially change any longer at selected temperature.

Abstract: PROBLEM TO BE SOLVED: To provide a discharging station for a bulk bag which is suitable for empting dangerous items in the bag without producing any dust and without any danger and an inner bag cab be washed and cleaned easily subsequently after the bag is evacuated. SOLUTION: A storing device is set such that an upward opened box 1 enclosing a releasing device is formed by a vertical wall 1a arranged at the storing device, height of the wall corresponds to at least a height of the bulk bag including a bulk bag holding device under measurement from a base bottom part of the releasing device. A supporting device 16 is provided with a closing device 14 for the box. A device 7 for use in sealing a gap formed between the bulk bag and a box wall is arranged at the upper half section of the box.

Abstract: PROBLEM TO BE SOLVED: To carry out discharge without contact with a filling product by forming a double cylinder device an inside cylinder, an outside cylinder arranged in the circumference of the inside cylinder and having a discharge port installed on a lower edge and an upper edge of a ring gap formed in accordance with the inside cylinder and the outside cylinder of a closed ring free to elevate to close them. SOLUTION: An outlet of an inner sack 18 is exposed by opening a sack closing part of a lower level after firmly positioning a bulk cargo by a holding device 3. A welded seam of the inner sack 18 is separated by passing an outlet neck part recirocally inserted in and out of the inner sack 18 and an outer sack 17 through an opened closing ring 9. A gripper device 21 is positionally fixed on a lower edge of the outlet of the inner sack 18, the outlet neck part is introduced to the inside of a ring gap by actuating a draw gear, and the outlet neck part of the outer sack is positionally fixed by lowering the closing ring 9. Discharge is started by opening a sack closing part 15 on a higher level and a double cylinder device is lowered.

Abstract: Production of alkali(ne earth) metal salts of 2,4-dichloro-6-hydroxy-s-triazine by hydrolysis comprises dosing cyanuric chloride (I) powder or aqueous suspension into an aqueous solution or suspension of 1.2-5 equivalent alkali(ne earth) hydroxide (II)/mole (I) and keeping the pH at 9.5-14 at ≤ 10 degrees C. Production of alkali(ne earth) metal salts of 2,4-dichloro-6-hydroxy-s-triazine by hydrolysis comprises dosing cyanuric chloride (I) powder or aqueous suspension into an aqueous solution or suspension of 1.2-5 equivalent alkali(ne earth) hydroxide (II)/mole (I) and keeping the pH at 9.5-14 at ≤ 10 degrees C. If less than the stoichiometric amount of (II) is present, the rest, including up to 25% excess, is added during and/or after addition of (I) to maintain the pH. Reaction is stopped when the pH no longer changes at the selected temperature.

Abstract: The device comprises a holding component (3) for the bulk bag and a container-shaped component which is upwardly open and centrally positioned beneath the holding component. The container-shaped device is formed as a double tube, having inner tube (20) and surrounding outer tube (7) with an outlet (8) at its lower edge and a raisable and lowerable closure ring (9) for closing the upper end of the ring gap formed by the two tubes. The emptying device has at least one grip component (21) movable forwards and backwards within the inner tube for holding firmly the outlet of the inner sack which can be drawn downwards by a tractive device operable from outside the double tube device.

Abstract: The emptying station for bulk-bags containing particulate material comprises a box with a funnel-shaped outlet (2, 3) at the bottom. The bag (10) is held on a lift device (16) and opened by three cutter blades (4a) forming a pyramid with a spike (4b) at its point. The novelty is that the lift carries a lock (14) for the box and a seal (7) closes the space between the bag and box below the holders (15) for the bag. An Independent claim is included for a method of emptying a bulk-bag using the station.
