摘要： A grinding apparatus includes a frame, a first grinding assembly mounted on the frame for rotating about a vertical axis and a second grinding assembly supported on the frame and sleeved around the first grinding assembly. The first grinding assembly has a substantially truncated cone-shaped member with an external frusto-conical grinding surface. The truncated cone-shaped member is tapered upward. The second grinding assembly has an internal frusto-conical grinding surface to contact the external frusto-conical grinding surface of the truncated cone-shaped member for grinding. A driving device is provided for rotating the first grinding assembly about the vertical axis with respect to the second grinding assembly.

摘要： A rail joint for interconnecting two successive rail bars of a railroad track includes longitudinally aligned first and second guide rails. Each of the guide rails has a mounting end adapted to be secured to a respective one of adjacent end portions of the rail bars, a distal end opposite to the mounting end and spaced from the distal end of the other one of the guide rails at an expansible space, and a downwardly and longitudinally extending dovetail projection. A connector is adapted to be fixed on the railroad track and is formed with an upwardly opening and longitudinally extending dovetail groove for receiving fittingly the dovetail projections of the guide rails therein so as to maintain alignment of the guide rails.

摘要： A grinding apparatus includes a frame, a driving device mounted in the frame, and an upper and a lower grinding member mounted coaxially on a vertical axis on the frame. One of the upper and lower grinding members is rotated by the driving device. The upper grinding member is movable in an upward and a downward direction. Each of the upper and lower grinding members has a grinding disc with a central opening, a disc seat holding the grinding disc, and a shaft carrying the disc seat. The grinding surface of the grinding disc of the uper grinding member is concave and the grinding surface of the grinding disc of the lower grinding member is convex so that both of the grinding surfaces of the grinding discs can come into snug contact with each other. A guiding device is provided for guiding the shaft of the upper grinding member which permits the upper grinding member to move vertically but prevents the same from lateral movement. Therefore, the upper and lower grinding members have large contact surfaces for grinding.
摘要翻译：磨削装置包括框架，安装在框架中的驱动装置以及同轴地安装在框架上的垂直轴上的上磨削构件和下研磨构件。上下研磨构件中的一个由驱动装置旋转。上磨削构件可向上和向下移动。上部和下部研磨构件中的每一个具有带有中心开口的研磨盘，保持研磨盘的盘座和承载盘座的轴。上磨削构件的研磨盘的磨削表面是凹形的，并且下研磨构件的研磨盘的研磨表面是凸形的，使得研磨盘的两个研磨表面彼此紧贴接触。引导装置用于引导上磨削构件的轴，其允许上磨削构件垂直移动，但是防止其相互横向移动。因此，上下研磨部件具有大的研磨接触面。

摘要： The disclosure herein describes an air-cleaning apparatus which comprises a frame support in the form of a rectangular hollow body including a first lateral wall having an inlet adapted for receiving exhaust and a second lateral wall opposite to the first lateral wall having an outlet for expelling cleaned exhaust; at least one filtering member removably inserted between the first and second lateral walls, which has a plurality of suitably dimensioned perforations formed therein, means for supplying a cleaning liquid, said means enabling said cleaning liquid to flow against said filtering member and spread over said perforations; and means for collecting said cleaning liquid. When a stream of the cleaning liquid is spread over the filtering member, a liquid film is effectively formed on the perforations therein, which will efficiently remove any pollutants existing in the exhaust so as to prevent air pollution from resulting therefrom.
摘要翻译：本文的公开内容描述了一种空气清洁设备，其包括矩形中空主体形式的框架支撑件，该框架支撑件包括具有适于接纳排气口的第一侧壁和与第一侧壁相对的第二侧壁，该第二侧壁具有用于排出的出口净化废气; 至少一个过滤构件可移除地插入在第一和第二侧壁之间，其具有形成在其中的多个适当尺寸的穿孔，用于供应清洁液体的装置，所述装置使得所述清洁液体能够抵靠所述过滤构件流动并且扩展穿过所述穿孔 ; 以及用于收集所述清洁液体的装置。当清洗液体流散布在过滤构件上时，在其上的穿孔上有效地形成液膜，这样可以有效地去除排气中存在的任何污染物，从而防止由此产生的空气污染。
