摘要： The present invention provides a process for generating acid-free lithium salt solutions for lithium and lithium ion batteries and for preparing high purity lithium salts. The invention comprises removing acid species from lithium salt solutions such as lithium hexafluorophosphate solutions using weak base resins. The process does not require the addition of a base such as ammonia which when added to the electrolytic solution generally must be removed from the final product. Once the lithium salt has been treated by the weak base resin, the substantially acid-free lithium salt solution may be recovered from the weak base resin to provide a solution which may be used as an electrolytic solution or which may be used to prepare high purity lithium salts. The highly pure salts and solutions have a hydrogen fluoride concentration of less than 10 ppm

摘要： An axle center for the forward axle in a vehicle having tandem drive axles includes a housing containing input, output and through shafts that rotate in the housing about a common axis on front, rear and through shaft antifriction bearings. The front and rear bearings, which support the input and output shafts, are mounted in opposition. The front bearing has an outer race provided with an external thread that engages an internal thread within the housing. That outer race is fitted with a locking ring provided with an inner flange that is engaged to turn the race and thereby bring the front and rear bearings into the correct adjustment. The locking ring also has an outer flange which is engaged with the housing once the front and rear bearings are correctly adjusted so as to maintain the correct adjustment.
