Title: Electric filter
Inventor: HATSUTORI SADAO
IPC: C02F1/28
Filed: 1979-03-01
Abstract: PURPOSE: To make the electric filter resist sufficiently even under the conditions of high temperature, high pressure and a condition of high radiation by a mechanism wherein the recombination means of cracked gas are mounted to the upper portions of electrode plates in the electric filter for removing ion-like impurities in a liquid, which is particularly used for a reactor water purifying system.  
     CONSTITUTION: A large number of electrode plates 2 are installed in parallel to the inside of a cylinder body 1 so that the plates run parallel with the flowing direction of water to be purified. Recombination means for gas formed in the case when removing impurities are mounted to the upper portions of the electrode plates 2, and the means are trough-like bodies 4 obtained by making up the layers of a platinum-palladium group catalyst on surfaces and may be manufactured by downward installing concave surfaces among the electrode plates or by directly applying 4a the said catalyst on the inwalls of flow paths. Thus, when DC voltage is applied among the electrode plates, ion-like impurities are adsorbed and removed, and cracked gas (hydrogen and oxygen) rapidly rises without stagnating on the surfaces of the electrodes and is returned to water by the recombination means.

Title: Production of low carbon killed steel by continuous casting method
Inventor: OONISHI TOSHIYASU
IPC: B22D11/115
Filed: 1981-02-19
Abstract: PURPOSE:To cast low C-killed steel which is less in central segregation and has no ultrasonic flaw detecting defects by supplying the molten steel of a specified amt. of C in a mold, drawing it out while agitating the same through electromagnetic induction under correct conditions and applying electromagnetic induction agitation at the end period of the solidification of the ingot. CONSTITUTION:Molten metal which is controlled of components so as to contain <=0.25% C is supplid into a casting mold by using an immersion nozzle and is cast while a flux is charged thereto. While electromagnetic induction agitation is applied to this molten steel by the magnetic field induced with the AC of 1.5-10.0Hz frequency and 195Xe<-0.18f=G<=1,790e<-0.20f> range of magnetic flux density G, it is drawn out continuously. The elctromagnetic induction agitation of about the same degree as that in the mold is applied around the axial center  of the ingot within the range of frequency f=1.5-10Hz in the magnetic flux  density G on the ingot surface to the molten steel in the end stege of solidification on the downstream of drawing out. Thereby, the generation of cavities in  the central part is eliminated, and the low C-killed steel of dense internal structure and good quality is obtained.
