    • The invention relates to a method for treating triazine-containing water of a melamine plant. The method is characterized in that the water containing ionic and non-ionic triazines in a dissolved form is fed to at least one membrane filtration unit, the water is separated into an ionic triazine-rich fraction and a non-ionic triazine-rich fraction in the membrane filtration unit, whereupon the ionic triazine-rich fraction is discharged and the non-ionic triazine-rich fraction is redirected into the melamine plant. The inventive method allows a great portion of the melamine contained in the triazine-containing water to be redirected into the process while the yield is increased along the entire melamine process. Furthermore, the need for fresh water in the wet part of the melamine plant is decreased. The disclosed method can be carried out continuously and in liquid phase.
    • 本发明涉及一种处理三聚氰胺植物含三嗪水的方法。 该方法的特征在于,将含有溶解形式的离子和非离子三嗪的水加入到至少一个膜过滤单元中,将水分离成富含离子三嗪的级分和富含非离子三嗪的级分 膜过滤单元,然后排出富含离子三嗪的级分,并且将非离子三嗪富集部分重新引导到三聚氰胺植物中。 本发明的方法允许包含在含三嗪的水中的大部分三聚氰胺被重新引导到该过程中,同时沿整个三聚氰胺过程增加产率。 此外,在三聚氰胺植物的湿润部分中需要淡水。 所公开的方法可以连续地和液相地进行。

    • The present invention is a novelty musical kettle that plays a song when liquid inside the kettle is heated. The kettle body contains a circular flute instrument with a release flap at a first end and a closed second end. When the water is heated, the flap opens allowing pressure to enter the instrument. Also, when the liquid is heated, a release strip releases a rachet which in turn releases a manually pre-wound rotating drum with a drive mechanism. As the drum unwinds, a plurality of multilevel cams along the drum's outer circumference lift a plurality of corresponding actuation valves. The actuation valves unseal and reseal a plurality of apertures along the circular instrument. When the aperture is open, the pressure inside escapes and a musical note is played. The unwinding drum continually unseals and reseals the apertures in a preprogramed manner, thus playing a song.
    • 本发明是一种新颖的音乐水壶,当壶内的液体被加热时播放歌曲。 壶身包含一个圆形长笛乐器,在第一端具有释放挡板,而封闭的第二端。 当水被加热时,阀瓣打开,允许压力进入仪器。 此外,当液体被加热时,释放带释放一个漏斗,这又释放了具有驱动机构的手动预缠绕的旋转滚筒。 随着滚筒的展开,多个沿滚筒外周的多级凸轮提升多个对应的致动阀。 致动阀沿圆形仪器开封并重新密封多个孔。 当孔径打开时,内部的压力逃逸并播放音符。 放卷鼓以预先编程的方式不断地打开和重新开启孔,从而播放一首歌曲。

    • An outer surface of a cam on a camshaft extending along a camshaft axis is honed by continuously rotating the camshaft about its axis, holding a grinding stone adjacent the cam with a surface of the stone directed radially inward at the cam surface, urging the grinding stone radially of the axis against the stone and thereby pressing the cam surface radially inward against the cam surface for contact of the stone surface along a line with the cam surface, and continuously displacing the stone surface in a direction generally tangential of the camshaft axis and thereby continuously moving the contact line between the cam and stone surfaces. Thus the contact line between the stone and the cam will move continuously, so that wear will not be concentrated in one location and the stone will not wear to fit in surface contact on the cam. The cam surface includes a part-cylindrical base region coaxial with the camshaft and a lobe region projecting radially outward from and joined to the base region. The stone surface is continuously displaced while engaging both of the regions.
    • 通过使凸轮轴绕其轴线连续旋转,将凸轮轴上的凸轮的外表面磨平,将磨石保持在凸轮附近,使石头的表面在凸轮表面径向向内指向,推动磨石 轴向径向地抵靠石头,从而将凸轮表面径向向内压靠在凸轮表面上,用于沿着与凸轮表面的线接触石表面,并且沿着与凸轮轴轴线大致相切的方向连续地移动石材表面,从而 连续移动凸轮和石材表面之间的接触线。 因此,石头和凸轮之间的接触线将连续移动,使得磨损不会集中在一个位置,并且石头不会磨损以适应凸轮上的表面接触。 凸轮表面包括与凸轮轴同轴的部分圆柱形基部区域和从基部区域径向向外突出并且连接到基部区域的凸起区域。 石头表面在接合两个区域时连续移位。
