Abstract: PURPOSE: To enhance crystal growth and to facilitate separation from mother liquor by crystallizing dibasic Ca(OCl) 2  in the presence of carboxylic acid (salt), such as succinic acid or maleic acid, or carbohydrate, such as glucose, as auxiliary crystallization agent.  
     CONSTITUTION: Crystallization of Ca(OCl) 2  is performed at 10W60°C, preferably at 20W40°C in the presence of normally 2% or less of carboxylic acid (salt), such as succinic acid or maleic acid, or carbohydrate such as glucose, galactose, or cane sugar, as auxiliary crystallization agent. The title product obtained by this process is crystals with well-grown c-axis, has a high mechanical strength as compared with conventional flat hexagonal plate crystal, and therefore is hard to crush. There is little mixing of the auxiliary crystallization agent. Also, NaCl and CaCl 2 , although highly concentrated, are little mixed into the crystal product. Moreover, after long periods of storage, decomposition of effective chlorine is only a very little, offering excellent storage stability.

IPC: H01F27/34
Filed: 1982-02-04
Abstract: PURPOSE:To prevent the generation of an exciting rush current, by flowing a DC to a  transformer to hold the magnetic flux density at a prescribed level and then applying  the voltage at a moment when the value of the magnetic flux density is equivalent to  the instantaneous steady level of the AC magnetic flux density which is produced by  the AC voltage. CONSTITUTION:A DC energizing switch 18 is turned on for a short time to connect a  DC power supply 20 to a winding of the power supply side before the AC voltage is  applied to a transformer 10. The iron core of the transformer 10 is magnetized to the  prescribed magnetic flux density B'r. The residual magnetic flux density of the transformer 10 is held at Br. A high-speed making device 16 is applied with the specific  phase of the AC power supply voltage corresponding to the time when the steady  instantaneous level of the AC magnetic flux density produced by an AC power supply  is equal to Br. Then the AC power supply voltage is applied to the transformer 10.  The above-mentioned specific phase is calculated and decided from the phase of the  power supply obtained from a transformer 22 by a power-on phase arithmetic circuit  24 and the power-on phase angle set by a setting circuit 26. Then a making coil 30 is  driven via a making command circuit 28. In such a way, the generation of an exciting  rush current is prevented by a simple circuit.
