摘要： A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B1) as material for production of steel. The grinding sludge containing the oil-based coolant and hardened component parts such as steel component parts that are used in bearings is compressed. To this end, the grinding sludge produced from a grinding line (1) is filtered by a filtering unit (4) to provide a concentrated sludge which is subsequently compressed by squeezing by a briquetting machine (5) to provide the briquette (B1). The briquette B1 so obtained can be reused as steel material. The coolant separated from the grinding sludge during filtering and squeezing is returned to the grinding line (1) through recovery passages (7, 8).

摘要： In the disclosed beam splitter, a first prism has an entrance face, an inclined face, and a mirrored face for totally reflecting a beam reflected from the inclined face back to the inclined face. A second prism has an entrance face in parallel with the inclined face of the first prism, and two exit faces. One of the exit faces of the second prism cooperates with the mirrored face of the first prism. When the first and second prisms are turned as a unit, the inclined face of the first prism either passes a light beam arriving from the entrance face through to the second prism and out one of the exit faces or totally reflects the arriving light beam to the mirrored face. The light beam reflected back from the mirrored face now passes through the inclined face to the second prism and out the cooperating exit face of the second prism.
