Inventor: FUKUMURA JITSUO
IPC: D04H1/541
Filed: 1994-03-01
Abstract: PURPOSE:To obtain wrapping paper having air permeability, simple structure and thermal adhesion without carrying out boring processing. CONSTITUTION:This wrapping paper 1 comprises a double structure obtained by laminating a paper material 2 to nonwoven fabric 3. The paper material 2 is formed by mixing pulp with polyethylene fibers and making into paper. Consequently, the paper material 2 has air permeability by pulp and thermal adhesion by the polyethylene fibers. The nonwoven fabric 3 consists of sheath- core type fibers 3 composed of the core part made of a polyester and the coating part made of a polyethylene. Namely, the nonwoven fabric 3 shows relatively high strength by its core part and thermal adhesion by the coating part. Therefore, the paper material 2 and the nonwoven fabric 3 are thermally bonded mutually by heating the paper material and the nonwoven fabric in a mutually superimposed state to a thermal adhesion temperature while contacting under pressure to form the wrapping paper 1. The wrapping paper is used for wrapping a desiccant, etc.

Title: Casting refractory used in spout for removing silica from molten iron
Inventor: KATAOKA MAMORU
IPC: C04B35/657
Filed: 1992-02-19
Abstract: PURPOSE:To improve both the corrosion resistance and the durability by including a chrome.spinel having a specific grain size in a specified amount in an Al2O3-MgO-(partially SiO2)-based casting material. CONSTITUTION:In a casting refractory, useful in a spout for removing silica from molten iron and used for lining of the spout for carrying out the removal of silica with an iron oxide-based treating agent, a chrome.spinel having <=1.0mm grain size in an amount of 2-15wt.% is contained and the remainder is composed of another refractory and a binder. The chrome.spinel has high corrosion resistance to FeO and MgO is not present as a simple substance. Low-melting substances are hardly formed by reaction with SiO2 which a component of clay or silica flower to be blended. The grain size of the chrome.spinel is regulated to that described above by considering that the melting loss of the existing casting material is caused in the form of a preceding matrix. If the amount of the blended chrome.spinel is below the lower limit, effects of addition are not produced. If the amount exceeds the upper limit, the resistance to corrosion and infiltration is deteriorated.

Title: Determination method for minute amount of phosphoric acid in recovered nitric acid and radioactive organic solvent
Inventor: SHIBAYAMA HARUO
IPC: G01N31/00
Filed: 1992-02-19
Abstract: PURPOSE:To separate matrix completely, to capture a minute amount of phosphoric acid quantitatively and to perform determination with excellent accuracy by approximately the same preprocessing method even for any of recovered nitric aid and radioactive organic solvent. CONSTITUTION:When the quantity of recovered nitric acid sample solution is determined, alkaline aqueous solution is used, and hydrogen-ion concentration is adjusted to the pH value of 3-6. Then, zinc oxide powder is added. When the quantity of sample solution comprising radioactive organic solution is determined, the zinc oxide powder is directly added without the adjustment of pH, and the solvent is brought into contact with the zinc oxide powder with a magnetic agitator and the like. Thus, phosphoric acid is quantitatively captured, and insoluble residue can be formed. As the alkaline aqueous solution used in the pH adjustment of the recovered nitric acid sample solution, sodium carbonate aqueous solution, sodium hydroxide aqueous solution, ammonium hydroxide and the like are preferable. Of these, the sodium carbonate aqueous solution is optimum. After the insoluble residue is filtered and separated, concentrated nitric acid is added, and the residue is made to be solution. For the solution, it is preferable that phosphor is determined by chemical analysis and absorptiometry. The phosphoric acid can be determined at the level of ppm espetially by heteropoly-blue absorptiometry (chemical analysis).

Abstract: PURPOSE:To prevent an extreme dimensional error between blocks and the falling off of the blocks, from being generated even if the lifting or the like of the blocks is performed by bonding the concrete blocks to be solidified on the surface of filter cloth in a state that a tensile force is applied to the filter cloth and the cloth is stretched. CONSTITUTION:On the plywoods laid on a floor surface, filter cloth 4 is spread, and both the end sections are retained between two iron sheets 6, 6. After that, a wire rope 8 is hooked to the iron sheets 6, 6, and is stretched in both the directions, and in a state that it is stretched, on the filter cloth 4, concrete blocks 5 are bonded to be solidified at specified intervals. After they are solidified, and when the stretched state is released, then the filter cloth 4 shrinks, and a block mat in a state that spaces between the blocks are reduced is formed. As a result, even if a heavy load is applied to the blocks by the lifting or the like, the spaces between the blocks are hardly widened, and the generation of dimensional errors is reduced, and the blocks can be prevented from falling off or the like.
