摘要： This disclosure is directed to an apparatus and method for highly concentrating an already relatively concentrated feed stream in a two-stage freeze-crystallization system. The feed stream is introduced into the first stage freezer-crystallizer without prior dilution, which has heretofore been customary. Highly concentrated output is withdrawn from a first stage wash column. Diluted concentrate is recirculated in the second stage of the system. This relatively simple expedient of diluting in the second stage, rather than in the first, allows the system to treat highly contaminated feed streams directly and produces significant savings in energy for the same throughput.

摘要： Apparatus is presented for slicing a large round bale into two or more parts prior to discharge from the baler. Slicing is accomplished by inserting a knife blade into the bale-forming chamber during or subsequent to the tying-off event while the bale rotates. The cutting means is inserted into the sidewalls of the baler and into the baling chamber. As the bale is rotated, the cutting means cuts the bale. Typically, a ring and core are formed. The preferred configurations of the core are cylinders or conical structures.
摘要翻译： 提供的设备用于在从打包机排出之前将大圆包分切成两个或多个部分。 在打包事件期间或之后，当捆包转动时，通过将刀片插入捆包形成室来实现切片。 切割装置插入打包机的侧壁并进入打包室。 当捆包被旋转时，切割装置切割捆包。 通常，形成环和芯。 芯的优选构型是圆筒或圆锥形结构。

摘要： An abrasive device is defined by a honeycomb or cellular structure which is configured to define the grinding device. The cells of the cellular structure are filled with the normal constituents that make up a grinding wheel such as abrasive grains, a bonding matrix such as an organic resin, and fillers. The bonding matrix acts to bond the abrasive grains together into a uniform mass. The bonding medium is also designed to bond the abrasive and fillers to the walls of the cellular structure.
