    摘要： A rotating preparatory abrasion roller finely abrades the surface of a web, which is to be a support of a lithographic plate, in preparatory abrading prior to main graining for graining the surface of the web. The preparatory abrasion roller, which is arranged against one surface of the running web, is pressed into an interval between a pair of supporting rollers, which are arranged at a predetermined interval against the other surface of the web. Consequently, the surface of the web is finely abraded in contact with a relatively large area on the surface of the preparatory abrasion roller in the state wherein the web laps with the part of the preparatory abrasion roller.

    摘要： Novel, composited silica catalyst supports suitable for commercial utilization, which may typically have an average pore diameter in the range of about 100 to about 5000 Angstroms, an advantageously high surface area in the range of about 20 to about 125 square meters per gram and a bulk density in the range of about 0.3 to about 0.6 gram per cubic centimeter, are made by mixing amorphous silica powder having an average particle size in the range of about 10 to about 50 millimicrons with a medium suitable for binding the silica powder. The mixture of silica powder and binder is formed into suitable, macrosized catalyst support shapes by press molding, extrusion, tableting and like forming means. The shaped mixtue of silica powder and binder is calcined to form the novel silica catalyst supports.

    摘要翻译： 适用于商业利用的新颖的复合二氧化硅催化剂载体，其通常可具有约100至约5000埃的平均孔径，有利的高表面积为约20至约125平方米/克， 通过将平均粒度在约10至约50毫微子范围内的无定形二氧化硅粉末与适于结合二氧化硅粉末的介质混合，制成约0.3至约0.6克/立方厘米范围内的堆积密度。 二氧化硅粉末和粘合剂的混合物通过压制成型，挤出，压片等形成手段形成合适的宏观催化剂载体形状。 将二氧化硅粉末和粘合剂的成型混合物煅烧以形成新的二氧化硅催化剂载体。

    摘要： A stoning or honing device for automatically applying an essentially constant and uniform pressure of an abrasive hard component onto a suspended portion of a continuously moving metal strip surface, for the purpose of defect visual inspection, includes: a main frame supporting at least one carriage bearing a hard component, the carriage being connected to a drive system for moving the hard component towards the metal strip and to apply a controlled contact pressure thereof on the metal strip surface; and a means for moving transversally and back and forth at a defined speed the hard component bearing carriage with respect to a continuous motion direction of the strip. The device includes, on each strip side, a plurality of hard component bearing carriages having each a defined width stroke and arranged according to at least three different locations respectively associated with three separate rails including drive and control systems.
