Abstract: A process for manufacturing a silica porous material with high solid acidity, catalytic activity and adsorption ability as well as excellent crystallinity and heat resistance has the steps of adding a compound of metallic element such as Al to a waterglass, aging the resultant mixture, calcining the aged mixture to form a layered crystal, incorporating an organic substance between layers of the layered crystal, calcining the resultant layered crystal for crosslinking the layered crystal. By this process, a plurality of layers formed of SiO.sub.4 tetrahedral and metallic oxide constitute a silica porous material, and the gap between adjacent layers of the layered crystal is reduced at a crosslinking site, while the gap of the other portion is expanded to form a micro pore.

Abstract: A catalytic combustion type exhaust gas processing device wherein noxious/smelly components contained in exhaust gases are deodorized and purified through sequential oxidative decomposition by at least one catalyst layer composed of platinum and/or palladium catalyst and a copper-cerium catalyst comprising chemically active species of copper and cerium in a compounded form. The device can be applied effectively to a drying furnace, for example, used in a coating for automobile use.

Abstract: Composite material with high mechanical strength and excellent high-temperature characteristics comprising a polymer matrix containing polyamide and layers of a silicate uniformly dispersed in the order of molecules in the polymer matrix, each of said silicate layers being 7 to 12 .ANG. thick and the interlayer distance being at least 20 .ANG.; and a process for manufacturing such composite material.

Abstract: A coating composition comprises a film forming component including resin and 0.05 to 20% by weight, based on 100% by weight of the film forming component, of at least one hydroxide selected from among calcium hydroxide, aluminum hydroxide, magnesium hydroxide and zinc hydroxide. The coating composition gives excellent resistance to filiform corrosion to an article under high humidity and under a long term exposure.

Abstract: Method and apparatus for carrying out the filling operation in a jet loom, wherein a main nozzle is provided for flying a weft through a guide passage formed on a sley at the time of each filling operation. When the supply of a compressed fluid into the main nozzle is stopped immediately after the completion of a filling operation, the compressed fluid present between a transfer valve connected to a fluid supply source and the main nozzle is positively discharged into the atmosphere simultaneously with the stopping of the supply of the compressed fluid, so as to promptly reduce the fluid pressure in the main nozzle, by utilizing the transfer valve designed for the present invention.
