Title: Oxidation of acenaphthene
IPC: C07C51/31
Filed: 1929-08-16
Abstract: 318,617. Selden Co., (Assignees of Jaeger, A. 0.). Sept. 7, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Oxidation products of acenaphthene or acenaphthylene or their substitution products; acenaphthylene.-Acenaphthene or acenaphthylene or their halogen or other substitution products are oxidized in the presence of an oxygen-containing gas such as air, using as catalysts the salts of the metal acids of the fifth andsixth groups of the periodic system. The salts used are preferably those of metals other than the alkali or the alkaline earth metals: especially effective salts are the vanadates, vanadites and molybdates of iron, silver, manganese, and aluminium. The salts of nickel, cobalt, copper, chromium, titanium. zirconium, thorium, cerium, lead, cadmium, and zinc may also be used but are somewhat less effective; salts of other metal acids of the fifth and sixth groups such as tungstates, chromates, uranates, tantalates, and columbates are also effective. Complex salts such as the vanadylvanadates of silver, copper, and alkali metals may be used. The acenaphthene substances are led together with an oxidizing gas such as air, preferably diluted with steam, at an elevated temperature over a contact mass containing one or more of the above-mentioned catalysts. The product may contain acenaphthylene, acenaphthaquinone, bisacenaphthylidenedione, naphthaldehydic acid, naphthalic anhydride, hemimellitic acid and maleic acid, the degree of oxidation being controlled by the temperature and the ratio of oxygen to acenaphthene. The catalyst may be impregnated or coated on to a carrier material such as pumice fragments, " Celite " brick fragments, etched quartz fragments or etched metal fragments such as those of aluminium or various ferrous alloys. An example is given in which a mixture of acenaphthene and air is passed over a catalyst prepared by coating pumice fragments' with ferric pyrovanadate. Naphthalic anhydride is obtained. The temperature of the converter is conveniently kept constant by means of a bath of boiling metal such as mercury-cadmium or mercury-lead alloy. In a further example, acenaphthene is vaporized with air and passed at 380-420 C. over a catalyst obtained by uniformly coating etched quartz fragments with lead vanadate. Acenaphthylene is obtained as the main product. Another example is given in which acenaphthene is vaporized with air and steam and passed at 370-390 C. over the contact mass of porous silver vanadyl-vanadate obtained by melting together silver nitrate and vanadium pentoxide. Naphthalic anhydride is the chief product. In place of or in addition to silver vanadyl-vanadate, one or more of the vanadylvanadates of sodium, potassium, lithium, rubidium or caesium may be used.

IPC: D03D3/00
Filed: 1960-07-20
Abstract: 928,477. Seaming non-metallic sheet material; endless belts. COURTAULDS Ltd. July 19, 1961 [July 20, 1960], No. 25239/60. Classes 42 (1) and 74 (2). An endless band is formed by joining together the two ends of a woven fabric by removing a plurality of picks from each end of the fabric and re-weaving the resulting free warp threads with a weft over a predetermined length and securing the interwoven threads in position over the length of the join. In one embodiment, Fig. 2, a number of weft picks are removed from each end of the fabric leaving isolated warp ends 1 and alternate warp threads are cut off before the final pick 2, as shown. The remaining warp threads are woven into the spaces from which these threads have been removed. The overlapping warp thread ends are joined by heat welding, fusing with a solvent or applying a suitable adhesive. Finally, a resin adhesive finish may be applied to the join and adjacent areas of the band. In an alternative embodiment, Figs. 4 and 5, for mechanically joining the fabric ends, the weft of the join is formed by parallel threads 11 drawn through a reed 12 and through the eyes of heald wires in harness frames 13 and which are held at one end by a roll 14 and at the other by a spring-compensated frame 15. The fabric 16 with the warp ends 17 frayed down free of weft is positioned with its weft parallel to the threads 11 and the end picks 22, 22<SP>1</SP> situated one pick distance away from the adjacent thread 11. With the shafts and reed manipulated by hand, the warp ends 17 are woven alternately from each end of the fabric, the warp ends 19 prior to being woven being held under the machine by a rubber clip device 20. The ends 18 which protrude after weaving are brought to the upper surface of the join and are trimmed after removal of the band from the machine. The ends are then joined. Preferably, the threads 11 are crimped prior to weaving the join by weaving yarn into the threads 11, steaming and then removing the unrequired yarn, preferably leaving in the yarn 21 right up to the edge of the band. Materials specified for the band are nylon, polyethylene terephthalate, polyethylene, polypropylene, polyurethanes or cellulose acetate, both secondary and triacetate.

Abstract: 1,053,193. Alkanol amine salts of alkyl acid orthophosphate esters. E. I. DU PONT DE NEMOURS & CO. June 15, 1965 [June 15, 1964; Jan. 13, 1965], No. 25243/65. Heading C2C. [Also in Division C5] The invention comprises a salt of a primary mono- or di-alkyl orthophosphate ester in which each alkyl group contains from 8 to 16 carbon atoms and an alkanol amine having the formula wherein R and R<SP>1</SP> are hydrogen or alkyl, cycloalkyl, phenyl or alkyl phenyl groups, R and R<SP>1</SP> together containing a total of from 8 to 24 carbon atoms, R<SP>11</SP> is an alkyl, cycloalkyl, phenyl or aralkyl group containing 6 to 25 carbon atoms and R<SP>111</SP> is hydroxyethyl or a hydroxypropyl radical. The salt may be prepared by neutralizing the alkyl orthophosphate ester with the appropriate alkanol amine, the reactants normally being in equimolar proportions. The orphosphate esters may be obtained by reacting an alcohol (3 moles) with phosphorus pentoxide (1 mole) to give an approximately equimolar mixture of the corresponding mono- and di-alkyl esters of phosphoric acid. This mixture may be used as such to prepare a mixture of amine salts or the separate esters may be isolated from it and used to prepare individual amine salts. The alcohols used may be branched- or straight-chain primary alkanols having 8 to 16 carbon atoms or mixtures thereof. The branched-chain alkanols may be those prepared by the Oxo-process using a branchedchain olefin such as C 7 -C 15  mono-olefinic polymers and interpolymers of propylene and butylene, or they may be prepared by the aldolisation of appropriate aldehydes followed by hydrogenation or by the alkaline condensation of primary alcohols of the type RCH 2 CH 2 OH where R is an alkyl group of from 2 to 6 carbon atoms. The alkanol-amines of type A above may be obtained by the reaction of the appropriate amine RR<SP>1</SP>NH with 3-chloropropanediol-1,2 and those of type B may be prepared by reading the appropriate amine R<SP>11</SP>NH 2  with ethylene oxide or propylene oxide or, when R<SP>111</SP> is hydroxyethyl, by reacting the alkyl or aralkyl chloride R<SP>11</SP>Cl with diethanolamine. The amine phosphate salts are useful as anti-stalling additives for hydrocarbon distillate fuels (see Division C5).

Filed: 1920-09-02
Abstract: 172,387. Smith, H. H., and Healey, T. G. P. Sept. 2, 1920. Dynamos, regulating.-In a dynamo in which the air-gap is automatically varied by speed changes in order to maintain constant output, the regulation is effected by a governor ring which surrounds and is pivoted on the armature shaft and is linked to the sliding armature so as to move it longitudinally with regard to the magnet poles under centrifugal action. In the form shown, the armature a and poles b are coned and the armature is carried on a feathered sleeve c slotted at c<1> for the passage of the governor-supporting pin f<1> and pressed towards the magnets by a spring e. The governor consists of a ring f linked to the armature at g and normally resting in an inclined position. At high speeds the plane of the ring tends to become normal to the shaft axis and the armature is thereby drawn out of the field against the action of the spring. The Provisional Specification states that the ring may be alternatively coupled to a sliding field magnet which surrounds a rotating but non-sliding annature with the ring pivoted on its shaft.

Title: Process of producing sheetings from a water-soluble, film-forming material
IPC: B29C48/91
Filed: 1946-08-24
Abstract: Sheets, films, or foils, are made by casting a water-solution of a water-soluble film-forming material, e.g. gelatin, pectin, water-soluble cellulose ethers, or polyvinyl alcohol, on to a flat and smooth vitreous surface in the presence of a quaternary ammonium, a phosphonium, or a sulphonium compound, containing as one of the substituents of the N, P, or S atom, an aliphatic radical of 4-20 carbon atoms, and containing an acid radical as another substituent. The cast layer is dried at a temperature below 70 DEG  C., and the dried sheet is stripped from the vitreous surface.  In the case of quaternary ammonium compounds, the N atom may form part of a heterocyclic nucleus of 5 or 6 atoms.  The presence of the onium compound facilitates the stripping of the sheet or film from the vitreous surface.  The compound may be added to the film-forming solution, or the vitreous surface may be coated with it.  Dodecyl pyridinium bromide, dodecyloxymethyl pyridinium chloride, octadecyloxymethyl triethyl ammonium chloride, dodecyl-triethyl-ammonium chloride, dodecyl-quinolinium bromide, N-methyl-N-octadecylmorpholinium chloride, lauroyl aminomethyl pyridinium chloride, dodecyl trimethyl phosphonium bromide, dodecyl diethyl methyl phosphonium bromide, dodecyl dimethyl sulphonium methyl sulphate, and cetyl dimethyl sulphonium methyl sulphate, are specified onium salts. Derivatives of pyridine, lutidine, quinoline, d.l-coniine, pyrrole, pyrrolidine, or piperidine, may be used.  When used as a coating, the onium compound may be dissolved in water, an aqueous alcohol, or an aqueous ketone.  The casting-surface may be a plate of glass, silica, quartz, porcelain, or enamelled metal.  In an example, a solution of gelatin containing glycerin and formaldehyde is cast on to a glass plate which has previously been treated with a 5 per cent solution of dodecyl pyridinium bromide and dried.  The glass plate and the gelatin layer are chilled at 0 DEG  C. to set the gelatin mixture.  The film is allowed to dry at room temperature and is then stripped from the plate.
