摘要： PURPOSE:To obtain an anode without casting flash by spreading or applying oil containing a material to be refractory powder after burning on circumference of the inside of a mold preceding to pouring of molten copper into the mold. CONSTITUTION:At the time of casting the copper anode, the oil containing the material to be the refractory powder after burning is beforehand spread or applied on the circumference 2a of the inside. By this method, at the time of pouring the molten metal, the casting flash is not caused on the interface between the circumference 2a of the inside of the mold and the molten metal and the outer edge part at the upper side of the obtd. copper anode can be formed in the extremely smooth state. Further, by interposing the refractory stuck to the circumference of the inside of the mold in between the molten metal and the mold, wettability with the molten metal is deteriorated and heat conductivity near the circumference of the inside of the mold is lowered so as to obtain the smooth copper anode without casting flash.

摘要： PURPOSE:To provide a lead-acid battery with little self-discharge. CONSTITUTION:The ear parts 1a, 2a of a laminated body 5 of electrode plates is cut to neatly arrange the heights of the end surfaces 1b, 2b of the ear parts 1a, 2a. The end surfaces 1b, 2b of the ear parts 1a, 2a are pressed onto a woven fabric of fiber or non-woven fabric 10 upper surface in which a flux 8 is absorbed to adhere the flux 8 to the end parts of the ear parts 1a, 2a. The end parts of the ear parts 1a, 2a are then dried to form straps by means of cast-on strap method, and the straps are bonded to the end parts of the ear parts 1a, 2a. The flux is hardly adhered to parts other than the bonding part of the ear parts to the straps, and a lead-acid battery with less self-discharge can be provided.

摘要： PURPOSE:To enable continuous casting of grid bodies having good characteristic by supplying molten metal into mating molds slidingly moved to fixed plates from a supplying hole at one side of the fixed plates and discharging the excess molten metal from discharging hole at the other side of the fixed plates. CONSTITUTION:The belt-like fixed plates 8, 8' arranged at right and left sides of the mating molds 1, 3, are heated at 400-450 deg.C. with heaters 20, 21, 20', 21' built in the fixed plates. In this condition, the annular molds are worked and when temp. of the molds 1, 3 reaches to about 150 deg.C, machine oil as mold release agent coats surface of the mold. Then, at the time of feeding out the molten metal preheated at 450-500 deg.C by working a lead pump, flow of the molten metal fills up the grid body sculptured grooves 10, 10' in the mating molds 1, 3 through a supplying hole 9 and returns back to a molten metal vessel through a discharging hole 9'. In this result, the grid having good voltage characteristic is obtd. The manufactured continuous grids are cut after filling up the lead battery paste to make pole plates.

摘要： PURPOSE:To prolong the life of a mold for an anode by cutting slits having a specified width each in advance on the edge part of a mold from the outside of the edge part. CONSTITUTION:The slits are cut respectively on the edge parts A, B of the mold for the anode in advance from the outside of the edge part. The width of the slit is given by 0.1 - 5.0 mm. Consequently, since the surface of the anode obtained is not rough, short circuits hardly occur in an electrolyzing time and electrolytic copper excellent in quality can be obtained.
