Water is added to cause stratification, and the naphtha layer distilled in vacuo up to 140 DEG  C. to remove the naphtha.  Chlorinated paraffin wax may be replaced by high molecular weight unsaturated hydrocarbons or chlorinated waxes obtained by polymerization and halogenation of olefins.ALSO:Compositions of use as low temperature lubricants comprise 50-90, preferably 65-85 per cent of a trialkyl phosphate, such alkyl group having not more than 12, preferably 4-9, carbon atoms, and 5-25, preferably about 10-20 per cent of a triaryl phosphate, in which one or two of the aryl groups is unsubstituted phenyl, the remaining group or groups being substituted phenyl, preferably alkyl substituted phenyl containing not more than 5 carbon atoms in each alkyl group, e.g. tolyl, xylyl, cumenyl or pseudocumenyl.  Suitable trialkyl phosphates are tri-butyl, hexyl, octyl, nonyl, and particularly tri (2-thylbutyl), (2-ethylhexyl), and (3, 5, 5-trimethylhexyl) phosphates, or mixtures thereof.  Triaryl phosphates include diphenyl cresyl (or xylyl, ethylphenyl or o-chlorphenyl) phosphates or mixtures.  Viscosity index improvers which may be present up to about 25 per cent include polymerized olefines, silicones, and esters of the acrylic acid series, the latter of average M.W. 5,000-25,000. Corrosion-inhibitors and anti-oxidants include epoxy compounds, especially glycidyl ethers in amounts of 0.5-5 per cent, and olefine oxides and derivatives, especially in combination with hydrocarbyl sulphides such as .05-1 per cent of benzyl, butyl or wax disulphide, the latter prepared from chlorinated paraffin or synthetic wax and sodium disulphide. Other inhibitors include hydroxy aromatic carboxylic acids, alkyl malonic acids, polyvalent-metal salts of hydrocarbon sulphonic acids, amines, amino phenols, and other substituted phenols. Minor amounts of mineral oils, synthetic lubricants, and flame-proofing compounds may be included.  Synthetic lubricants may be polymerized alkylene oxides or glycols, and esters of dicarboxylic or other acids.  Examples are given of compositions containing tri (2-ethylhexyl) phosphate, diphenyl cresyl phosphate, "Acryloid" (solution of polymerized methacrylic esters), and glycidyl phenyl ether, with or without wax disulphide.

Abstract: 350,673. Aircraft landing &c. lights. CHANCE BROS. & CO., Ltd. and GOODMAN, H. E. E., Lighthouse Works, Smethwick, Staffordshire. May 8, 1930, No. 14153. [Class 75 (ii).] Adjusting reflectors from a distance.-Relates to aircraft landing or like lights of the kind in which a gimbal-mounted reflector is capable also of axial movement as a whole for controlling both the direction of the beam and also its divergence and consists mainly of a double-jointed pilot's lever by which the movements of the reflector are effected. The reflector G is carried by a gimbal ring d, d<1> and is mounted for axial movement therein by means of spring-controlled sliding stems f. These movements are effected through four cables h attached to the reflector at symmetrically disposed points i and at their other ends carried over grooved segments p on the operating lever, Figs. 3 and 4. This latter comprises two parts j, k connected by a ball joint l, m and mounted at its lower end on a pivot which is normally locked against rotation by a wedge u causing sliding parts o of the pivot to engage serrated clutch faces v. The wedge is released, against the action of its locking spring q, by depressing the central two-part rod r, s and the lever can then be moved about the bottom pivot to pull all four cables and thus cause axial movement of the reflector. When the bottom pivot is allowed to remain locked however the only movement possible is a universal movement about the ball joint l, m, thus effecting a corresponding swivelling movement of the reflector.
