Condensed steam containing oil emulsified therein and/or salts dispersed or dissolved therein is purified by supplying the condensed steam to an arrangement of two concentric anodes 6 and 8 with a cathode 7 therebetween, the electrodes being formed of porous corrosion resistant material and subjected to an impulse direct current. Electrolysis of water present causes gas bubble formation and format...

PURPOSE:To manufacture a plate for lead-acid battery having low fluid strain and high accuracy by arranging separating sheets on the upper and lower sides of a plate to prevent active material from bonding to a press mold when the plate is manually pressed to adjust its thickness. CONSTITUTION:A plate 3 inserted into a press mold 1 with a plate transfer robot 4. A separating sheet 2 is set in the ...

PURPOSE:To effectively perform formation in a short time to increase productivity without decrease in the battery performance and increase in cost by once raising temperature of a battery and then cooling it in the initial charge. CONSTITUTION:In a process in which formation is performed with a battery cooled in a water both, after formation has been made to 1/10-1/2 of the formation capacity, the...

PURPOSE:To manufacture a plate whose initial performance is increased and self-discharge rate is decreased by suspending the formation for a specified time, and immersing the plate in dilute sulfuric acid solution having the same as or higher than that for formation, then continuing formation. CONSTITUTION:Formation is suspended for 5 hours or more after proceeding 60-10% of theoretical formation ...

PURPOSE:To prevent generation of cracks in gelled electrolyte by pouring a mixture of a silicic acid aqueous solution having a specified concentration and suffuric acid solution in a battery and vibrating the battery for a specified time. CONSTITUTION:A mixture of a silicic acid aqueous solution having a specified concentration and sulfuric acid solution is poured in a battery 1. Then, vibration b...

PURPOSE:To insert a plate group into an outer jacket bag easily and accurately and to reduce the stay of excess electrolyte by making the inner dimension of an opening larger than the outer dimension of a plate group, but making the inner dimension of the plate group setting part similar to the outer dimension of the plate group. CONSTITUTION:When a plate group 1 is inserted into an outer jacket b...

PURPOSE:To provide a small lead-acid battery by forming an exhaust valve in a back seal having cylindrical structure formed by sealing both ends of a folded plastic film or sheet. CONSTITUTION:A plastic film or sheet is folded and formed in a cylindrical bag 11 by a back seal 12. The upper and lower sealed parts 13, 14 are sealed to form a lead-acid battery 10. In the back seal 12, an unsealed par...

PURPOSE:To easily and efficiently obtain a storage battery having desired voltage by previously manufacturing a large bipolar storage battery having a large number of cells, then cutting off a container according to desired voltage. CONSTITUTION:Lead alloy grid frames 4, 4' are melt-bonded on both sides of a plastic plate 2. A cathode active material is filled in one frame 4 and an anode active ma...

PURPOSE:To uniformly disperse an electrolyte inside a battery to increase performance by assembling a battery with nonformed plates, and pouring excess electrolyte, then performing constant current formation. CONSTITUTION:A battery is assembled with nonformed plates, and the excess amount of electrolyte is poured in the battery, then constant current formation is performed. After completing the fo...

PURPOSE:To uniformly disperse an electrolyte inside a battery to increase performance by assembling a battery with nonformed plates, and pouring excess electrolyte, then performing constant current formation. CONSTITUTION:A battery is assembled with nonformed plates, and the excess amount of electrolyte is poured in the battery, then a rubber belt-shaped formation exclusive-use safety valve 1 havi...

A lead acid accumulator (1) with bottom connection comprises one or several pairs of accumulator cells (2, 3), each pair of cells being enclosed in a common cell vessel (4) with a liquid-tight partition wall (5) between the separate cells. The cell has a cover (6) with bores (7, 8) for the pole posts (9, 10). Each cell includes a positive (11 or 12) and a negative (13 or 14) group of electrodes, e...

A computer tomography apparatus has an x-ray source which is fed with a high voltage supply. Operation of the x-ray source over an extended period of time causes the focal spot on the anode to change position, thereby degrading the image which is constructed from the series of exposures, because construction of the image is based in part upon the focus being at a known position. A focus position c...

Rapid cooling of a freshly baked moisture-containing farinaceous foodstuff article such as bread, wherein the article at its baked temperature and without deliberate pre-cooling is submitted to a reduced pressure treatment, which is applied at a plurality of rates so that on the one hand the article is not disintegrated, and on the other hand the article does not suffer an unacceptable peripheral ...

The formation efficiency of pasted positive plates of a lead-acid battery is greatly enhanced by providing in situ a layer of lead dioxide (PbO2) on the pasted plate surfaces prior to formation. The PbO2 layer is preferably formed by treating the surfaces of the plates with an ozone-enriched gas to convert a portion of the poorly conductive positive active precursor material (nPbO.PbSO4) to electr...
