摘要： The present invention provides a novel process for the preferential chlorination of alumina over silica in the carbo-chlorination of kaolinitic ores to produce aluminum chloride. The process comprises introducing small amounts of alkali metal compounds with oxyanions into the carbo-chlorination process. Preferred embodiments are directed to particular compounds of alkali metals with oxyanions selected from the group consisting of carbonates, sulfates, hydroxides, oxides, phosphates, and the like. The present invention results in significantly reduced energy, manufacturing, and equipment costs and thus represents a breakthrough in the utilization of domestic ores such as kaolinitic clay for the production of aluminum chloride or alumina through oxidation of the aluminum chloride.
摘要翻译：本发明提供了一种用于在高岭石矿石的碳氯化中优先氧化二氧化硅以制备氯化铝的新方法。该方法包括将少量含有阴离子的碱金属化合物引入到碳氯化方法中。优选的实施方案涉及具有选自碳酸盐，硫酸盐，氢氧化物，氧化物，磷酸盐等的含氧阴离子的碱金属的具体化合物。本发明导致能量，制造和设备成本的显着降低，因此代表了通过氧化氯化铝来生产氯化铝或氧化铝的高岭土等家用矿石的利用的突破。

摘要： A safety razor comprises an elongated handle that has a pair of arcuate, laterally spaced guide rails; a support member that has a pair of elongated guide means for sliding cooperation with the respective guide rails; a spring that acts between the handle and the support member to bias the support member towards a medial position of pivotal adjustment relative to the handle; and a shaving unit for detachable interengagement with the support member to position its cutting edge parallel to the pivotal axis.

摘要： A safety razor head, which may be a replaceable cartridge or part of a disposable razor, has leading and following tandem blades fast with a guard member and a cap member, respectively. The members are pivotally mounted for angular movement independently of each other about spaced axes parallel with the blade edges. Alternatively, the members may be interconnected by flexible bridge portions to provide for the relative angular movement of one member and blade relative to the others.
摘要翻译：安全剃刀头可以是可更换的药筒或一次性剃须刀的一部分，分别具有带防护件和盖件的前后串联刀片。这些构件枢转地安装成用于彼此独立于角度运动绕轴平行于叶片边缘的间隔开的轴线。或者，构件可以通过柔性桥接部分相互连接，以提供一个构件和叶片相对于其它构件和叶片的相对角度运动。

摘要： A disposable razor has its head formed with a rearwardly directed pocket to receive the forward portion of the head of a second razor to its rear, so as to protect the cutting edge or edges of the second razor. The razors are firmly but releasably interengaged with each other by co-operating projections and recess.
摘要翻译：一次性剃刀的头部形成有向后指向的凹穴，以将第二剃刀的头部的前部接收到其后部，以便保护第二剃刀的切割边缘或边缘。剃须刀通过合作的突出部分和凹槽而牢固但可释放地相互接合。
