Title: An improved manufacture of lubricating oils
IPC: C10M131/12
Filed: 1932-05-07
Abstract: The viscosity index of hydrocarbon lubricating-oils is raised with reduction or without undesirable rise in the pour-point by adding waxy hydrocarbons and up to 10 per cent of a substance depressing the pour-point.  Compounding materials, e.g. rosin or lead or aluminium oleate may also be added.  Depressants specified are:--natural resinous materials, e.g. wax tailings, preferably mildly oxidized, gums occuring in gasolene, paracumarone resins, gum damar, and copals; the partial oxidation products of paraffin wax or waxy hydrocarbons, the acids isolated therefrom, or the zinc or magnesium salts thereof; and synthetic oils obtained by condensing waxy hydrocarbons with aromatics, e.g. benzol, toluol, naphthalene, anthracene, naphthols, anthrasols, substituted phenols, and aromatic gas oils.  In an example, a Colombian lubricating oil is treated with 5 lb. of 66 DEG  B<\>ae sulphuric acid per barrel and filtered with 5 lb. of clay per barrel; 8,5 lb. of the product, 1 lb. of petrolatum, and 0,5 lb. of a synthetic oil obtained by the condensation of naphthalene and chlorinated wax in presence of aluminium chloride, are mixed together; the viscosity index is raised from 50 to 60, and the pour point reduced from 0 DEG  F. to -10 DEG  F.  The depressant is made by blowing chlorine through paraffin wax at 200 DEG  F. in presence of a trace of iodine until 10-12 per cent of chlorine is absorbed; dissolving in kerosene 90 lb. of the chlorinated wax and 10 lb. of naphthalene, and reacting at room temperature for 24 hours with 10 lb. of aluminium chloride; then heating slowly to 200 DEG F., removing the sludge, and distilling off the kerosene and unreacted wax.  Or wax, petrolatum, or oil fractions containing large proportions of wax or long chain aliphatic hydrocarbons of molecular weight 200, 250, or higher, alone or mixed, may be chlorinated at 140-300 DEG  F., and 1,0 lb. of the chlorinated wax reacted at room temperature or at 140-160 DEG  F. with 0,1-0,5 lb. of a mixture of equal parts of aluminium chloride and the aromatic, preferably in presence of kerosene or other saturated solvent.ALSO:Oils for lowering the pour point of lubricants are made by condensing waxy hydrocarbons with aromatics, e.g. benzol, toluol, naphthalene, anthracene, naphthols, anthrasols, substituted phenols, and aromatic gas oils.  For example, chlorine is blown through paraffin wax at 200 DEG  F in presence of a trace of iodine until 10--12 per cent. of chlorine is absorbed; 90 lb. of the chlorinated wax and 10 lb. of naphthalene are dissolved in kerosene and reacted at room temperature for 24 hr. in presence of 10 lb. of aluminium chloride; the temperature is then slowly raised to 200 DEG  F., the sludge removed, and the kerosene and unreacted wax distilled off.  Or petrolatum or oil fractions containing large proportions of wax or long chain aliphatic hydrocarbons of m.w. 200, 250, or higher, alone or mixed may be the material chlorinated.

Abstract: In a process for tanning and re-tanning hides, pelts, e.g pickled pelts having a pH between 2.0 and 3.5, wool-skins, fur-skins and leathers, they are treated with a tanning agent comprising zirconium, aluminium and chromium salts, the proportion of these salts, computed as the proportion of the oxides ZrO2:Al2O3:Cr2O3, bein 100: 5-50: 2-30, preferably 100: 10-20: 3-8, by weight. The tanning agent may be a mixed complex of Zr, Al and Cr salts obtained by heating and/or dehydrating, e.g. evaporating, spray-drying or roller-drying, an aqueous solution containing them.  According to Example 1, a powdered Al-Cr mixed complex is prepared and mixed with aqueous, technical zirconium sulphate, the mixture is heated to 80 DEG  C., then cooled and spray-dried to yield a powdered tanning agent, in which the proportion of the oxides ZrO2:Al2O3: Cr2O3 is 100: 14: 7. Tanning may be effected first with a zirconium salt, and then with aluminium and chromium salts, e.g. in the form of a mixed Al-Cr complex described in French Specification 1,244,477.  The tanning agent may be in the form of an aqueous paste, a highly concentrated aqueous solution, or a powder.  Specified zirconium salts are: zirconium sulphate, e.g. containing finely divided silica gel, and zirconium oxychloride containing sodium sulphate. Specified aluminium salts are the sulphate, chloride and acetate. Specified chromium salts are the sulphate, nitrate, chloride, acetate and formate, and chrome alum. The tanning agent may also comprise one or more of the following acids and their sodium salts: sulphuric, phthalic, sulphophthalic, sulphosuccinic, tartaric, formic, acetic, lactic, glycollic and citric.  Resulting leathers may be re-tanned or after-treated with a mineral, vegetable, synthetic or resinous tanning agent, then dyed, fatliquored, filled and dried.  A suitable synthetic re-tanning agent is described in U.K. Specification 443,967. The following types of leather may be prepared using the process according to the invention: full grain leather, suede leather, nubuk, white or dyed glove leather, white splits, white belt leather, sole leather, aniline dyed kid leather and shrunk leather.

May 5, 1930, No. 13822. Convention date, Jan. 6. [Classes 39 (i) and 40 (v).] Relates to valve amplifiers of the kind in which the external anode resistance is in the form of a saturated diode valve; and comprises a valve construction in which this diode valve is constituted by the cathode and heater of the amplifying valve. As shown in the Figure, the diode valve is placed on the negative side of the HT battery B and is enclosed in the envelope of the valve 3. This valve is of the indirectly-heated type and the heater 9 forms the emission filament of the diode, the plate 8 of the diode forming the cathode of the main valve. This enables the heater 9 to be energized from the same supply T as the cathode of the following valve 13, the grid of which is connected through a coupling capacity 11 to the cathode 8. The saturation current of the diode is equal to the normal plate current of the main valve, and the emitter 9 is made of material of low electronic emission or the space between the emitter 9 and the cathode 8 is partially filled with insulating material. The Specification as published under Sect. 91 (3) (a) states that the emitter 9 may be of photo-electric material and may be illuminated by the incandescent filament of the main valve. It also comprises an arrangement in which a separate diode valve, or a troide valve with plate and grid united, is employed as the external plate resistance. This matter does not appear in the Specification as accepted.
