摘要： A method of removing Li.sub.2 O present in an electrolyte predominantly of LiCl and KCl. The electrolyte is heated to a temperature not less than about 500.degree. C. and then Al is introduced into the electrolyte in an amount in excess of the stoichiometric amount needed to convert the Li.sub.2 O to a Li-Al alloy and lithium aluminate salt. The salt and aluminum are maintained in contact with agitation for a time sufficient to convert the Li.sub.2 O.

摘要： An electrolytic process and apparatus for reducing calcium oxide in a molten electrolyte of CaCl.sub.2 -CaF.sub.2 with a graphite anode in which particles or other contamination from the anode is restricted by the use of a porous barrier in the form of a basket surrounding the anode which may be removed from the electrolyte to burn the graphite particles, and wherein the calcium oxide feed is introduced to the anode compartment to increase the oxygen ion concentration at the anode.

摘要： A device for conveniently sampling and testing oil from the crankcase of an internal combustion engine comprises a tubular member, installed in the dipstick guide tube of the internal combustion engine and having a chamber above the guide tube inlet, and a vacuum filled sample receptacle having a seal which, when the receptacle is inserted in the chamber, is opened causing oil from the crankcase to be drawn into the receptacle. When the receptacle is withdrawn from the chamber the seal automatically closes, providing a convenient container for the oil sample to be sent to a laboratory for analysis. Optionally, to test the oil for acidity at the time the sample is received in the receptacle, the receptacle may contain a reagent which will indicate by color the pH of the oil sample.
摘要翻译：用于方便地从内燃机的曲轴箱取样和测试油的装置包括：管状件，安装在内燃机的定尺导向管中，并且在引导管入口之上具有一个室，以及一个真空填充的样品容器，当容器插入腔室时，其被打开，导致来自曲轴箱的油被拉入容器中。当容器从腔室中取出时，密封件自动关闭，为油样提供方便的容器送到实验室进行分析。任选地，为了在样品接收在容器中时测试油的酸度，容器可以包含将通过颜色指示油样品的pH的试剂。
