Title: Improvements in and relating to metal pigment pastes and paints
IPC: C09D5/10
Filed: 1936-07-22
Abstract: A metallic pigment paste or paint is prepared by mixing a flake form metal powder, already possessing the property of leafing, with a paint vehicle and with one or more specified stabilizing agents.  The leafing property of the metal flakes is thus retained, and the pigment paste or paint remains homogeneous. Vehicles mentioned are aliphatic and aromatic hydrocarbons such as benzol, toluol, xylol, solvent naphtha, or a mixture of octanes, nonanes and decanes with or without undecanes and/or dodecanes, while other purified coal tar fractions, either as such or in the hydrated, hydrogenized, halogenated, esterified or oxidized condition, may be used.  The specified stabilizing agents are: alkali salts of aliphatic acids, e.g. sodium or potassium acetate, propionate and butyrate; high molecular weight fatty acids or weak inorganic acids, such as silicic acid and boric acid, in combination with an alkali metal, an alkaline earth metal or one of the remaining metals having an atomic weight under 50, e.g. alkali metal silicates and borates, potassium, sodium, lithium or aluminium stearate, palmitate, oleate and ricinoleate; terpenes, terpinyl bodies or their esters or derivatives, e.g. camphor, borneol, terpeneol, terpinyl acetate and bornyl oxalate; napthalene, anthracene, naphthyl alcohols, naphthyl acetate, chlorinated or brominated naphthalene; mono- and polyamines, substituted ammonias and quaternary ammonium compounds, e.g. aniline, toluidine, xylidine, toluylene diamines, xylylene diamines and phenylenediamines; alkylated anilines, toluidines, xylidenes, naphthalenes and anthracenes; urea, guanidine, urates and other nitrogen-containing organic compounds, and synthetic resins of the polychlorinated diphenyl type together with a dichlorethyl ether.  It is stated that the presence of benzol, toluol, xylol, solvent naphtha, and the pyridine, quinoline or acridine series of bodies will materially augment the mirroring properties of the pigment paste or paint.  Specification 391,839 is referred to.  According to the Specification as open to inspection under Sect. 91, the following substances may be present: cellosolve, cellosolve esters, e.g. acetate; chlorinated hydrocarbons, e.g. chlorethanes, chlorethylenes and chlorinated aromatic hydrocarbons; "a metal of Group III of the Periodic System of the Elements in ester form with an acid normally present in animal fats and oils"; and any metal salt of a paraffin acid or a high molecular weight fatty acid or a comparatively weak inorganic acid, but this subject-matter does not appear in the Specification as accepted.

Title: Friction clutch
IPC: F16D13/46
Filed: 1972-05-04
Abstract: 1394118 Friction clutches LUKLAMELLEN UND KUPPLUNGSBAU GmbH 4 May 1972 [4 May 1971] 20882/72 Heading F2C In a diaphragm spring friction clutch wherein a diaphragm spring 4 is positioned axially between a flywheel 2 and a presser plate 11, and urges the presser plate away from the flywheel to engage driven plate 12 between the presser plate 11 and presser plate 13 bolted to the flywheel 2, a stop member 18 is provided to limit the relaxation of the diaphragm spring to that which occurs at maximum wear of the friction linings to facilitate mounting and dismounting of the clutch assembly. As shown in Fig. 2 the stop member 18 has a portion 19 which hooks through a hole 20 of the flywheel 2, and also has a part 21a which hooks on to the spring 4, the stop member 18 being riveted to the presser plate 11 and serving to move it to the disengaged position on movement of the spring 4 through members 8 and 6. The portion 19 does not abut the flywheel 2 until the friction linings are worn to their maximum or until presser plate 13 and friction plate 12 are removed when the portion 19 holds the presser plate 11, and diaphragm spring 4 in position. Leaf springs 14 interconnect presser plate 11 and flywheel 2 for torque transmission. A further embodiment (Figs. 6 and 7, not shown) has presser p ates 11 and 13 interconnected by the leaf springs and in place of stop members 18 as shown has yokes which extend over the outer edge of diaphragm spring 4, on the opposite side from presser plate 11, and so limit the degree to which the diaphragm spring may relax, there being raised beads on the flywheel against which the spring can act until this relaxation (due to wear of the friction linings) is attained. In this embodiment the two presser plates (and driven plate) may be removed from the flywheel as a unit, without the diaphragm spring relaxing beyond this point. The leaf spring 14 may alternatively extend between presser plate 11 and flywheel 2 as in the embodiment shown. Several constructions are also described of the means by which thrust plate 6 is affixed to spring 4.

Patent GB-718567-A (GB)
Title: Improvements in and relating to gasoline fuels
IPC: C10L1/14
Filed: 1952-08-21
Abstract: A process for the preparation of an improved fuel composition comprises adding to a hydrocarbon oil of the gasoline boiling range, an organo-lead anti-knock agent and an oil-soluble unsaturated alicyclic compound boiling within the boiling range of the said hydrocarbon oil, in such quantities that the final composition contains between 0.05 and 3 theories, based upon the organo-lead anti-knock agent, of total oil-soluble unsaturated alicyclic compound.  The alicyclic compounds used contain one or more unsaturated bonds of olefinic or acetylenic character which are relatively reactive and are not that type of unsaturation peculiar to aromatic compounds.  The unsaturated linkage may be a side chain attached to the cyclic nucleus, but is preferably in the nucleus. These compounds include a -pinene, a -fenchene, dicyclohexadiene, indene, camphene, cyclohexene, a -terpinene and dihydrotoluene 1, 3. They are preferably used in conjunction with halogen-containing scavengers such as ethylene dibromide, ethylene dichloride, acetylene tetrabromide, hexachloropropylene mono- and polyhalopropanes, mono- and polyhalobutanes, mono-and polyhalopentanes and polyhaloalkyl benzenes.  The halogen scavengers are used in the same proportions (0.75 to 1.5 theories based upon the lead content) as would be used in the absence of the unsaturated alicyclic compounds.  The unsaturated alicyclic compounds may be mixed with the lead anti-knock compound (with which a halogen scavenger compound may already have been mixed) to form a concentrate for subsequent incorporation into gasoline base stocks.  The lead anti-knock compound is of the organo-lead compounds such as tetraethyl lead, which is used in quantities from 0.5 to 2 c.c. per litre in the case of aviation fuels.  Other additives such as corrosion inhibitors and stabilizers may be included, e.g. 2, 4-dimethyl-6-tertiary-butyl phenol and other alkyl phenols, N, N1-dibutyl-p-phenylenediamine, hydroquinone and phenyl-alpha-naphthylamine, and dyes.

Activated sludge issuing from the apparatus may be separated from the liquid mass and recycled. The fermentation apparatus may be maintained at an optimum temperature for developing the treatment micro-organisms, i.e. 12‹ to 40‹ C. The method is particularly applicable to the treatment of polluted water from sugar mills, this treatment being carried out in the apparatus shown in the accompanying Figure wherein waste sludge from sugar-beet mills after settling in tank 1 and the removal of grit therefrom, is fed to a fermentation apparatus and is mixed with incoming liquid. Air is supplied to this apparatus by the blower 5 to maintain a constant circulation of input liquid expanded by aeration. Aerated sludge loaded liquid is passed to settling vessel 7. Purified liquid passes out through duct 11, and settled sludge is recycled to the fermentation apparatus.
