Abstract: 534,212. Dewaxing mineral oils. NASH, A. W., and HUNTER, T. G. July 22, 1939, No. 21310. [Class 91] The wax content of a mineral oil is reduced by extraction with a solvent which is only partially miscible with the pure oil in the mixture and immiscible or only partly miscible with the wax in the mixture at an operating temperature equal to or above the melting point of the wax but below the critical solution temperature of the wax with the solvent. The residue from the extraction may consist either of an oil-wax mixture with a wax content higher than the original mixture or of wax entirely free from oil, depending on the extraction conditions employed. The solvent which is used may be an aliphatic saturated ketone, an aliphatic monohydric alcohol, a fatty acid, a monohydric phenol, a phenylamine, a nitro derivative of benzene or an alkyl benzene, a halogen ester of glycols, furfural, or furfuryl alcohol. Mixtures of two or more of the above solvents may also be used. The extraction may be carried out either in single batch extraction or by multiple or successive extractions using a stirring vessel to effect complete admixture. The counter-current process may also be employed. In examples (1) a wax containing oil was extracted by acetone at 25‹ C. (2) a wax containing hydrocarbon liquid was extracted counter-currently with aniline at 25‹ C.

IPC: H01J3/02
Filed: 1926-09-03
Abstract: 257,951. Siemens & Halske Akt.- Ges. Sept. 3, 1925, [Convention date]. Low-pressure metallic-vapour apparatus. - In a vapour rectitier or amplifier having control electrodes, a cooling device is disposed at or near the cathode space, and the main discharge path is divided by the cooling means in such a manner that in a part of the path the discharge is carried entirely by electrons. In the valve-amplifier shown in Fig. 2, the bulb consists of a spherical part 11 and two tubular parts 12. 13. The part 11 contains a mercury cathode 16 and a cooling spiral 17. The part 13 contains an anode 18, an amplifier anode 15, and a control grid 14. The cooling spiral prevents the passage of ions into the part 13 in which the discharge is entirely electronic. An auxiliary anode 19 receives any ions passing into the part 12. The degree of cooling should be such that the pressure of the mercury vapour is equal to that of the gas in the bulb. In another arrangement the part 12 and the anode 19 are dispensed with, and the part 13 is connected directly with the part 11 which contains a cylindrical cooling device passing through a mercury cathode into the cathode space. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the rectifier shown in Fig 1, (Cancelled), having a mercury cathode 4, two anodes 3, and a cooling ring 5. This subject-matter does not appear in the Specification as accepted.
