Abstract: In a process for producing aluminum by electrolysis of alumina dissolved in a cryolite-based molten salt contained between a cathode and a plurality of previously baked carbon anodes which are consumed with evolution of oxides of carbon, the improvement including setting all anodes at the same time.
Abstract: A formation process of an amorphous silicon film, which process comprises subjecting a higher silane containing at least two silicon atoms to photochemical decomposition under radiation of a light having a wavelength of 300 nm or shorter so as to cause amorphous silicon to deposit on a substrate.
Abstract: An improved solvent extraction process is described for the preparation of lube oil products, the improvement whereby the solvent contains an additive which facilitates phase separation and increases the yield of raffinate.

Abstract: PCT No. PCT/DE78/00024 Sec. 371 Date May 11, 1979 Sec. 102(e) Date May 11, 1979 PCT Filed Sept. 14, 1978 PCT Pub. No. WO79/00145 PCT Pub. Date Mar. 22, 1979Liquids with a very low conductivity are sterilized by means of anodic oxidation. For the purpose of increasing the conductivity without using chemically soluble additives, a gas which increases the conductivity, in particular CO.sub.2, is fed to the liquid before the anodic oxidation. For the purpose of carrying out the process, a device with an oxidation reactor (1) has a feed line (5), on the inlet side, for the gas to be fed in and a venting means (22) on the outlet side.
