Patent GB-468648-A (GB)
Title: Manufacture of vat-dyestuffs and intermediates
Filed: 1936-02-14
Abstract: Vat dyes or intermediates are made by heating fluoranthene with an o-dicarboxylic acid anhydride in presence of a condensing agent, at least 2\ba1/2\be mols. of the anhydride being used for each mol. of fluoranthene.  The product may be halogenated.  The process may be carried out in one stage, or by using first 1 mol. of the anhydride for 1 mol. fluoranthene to produce a monoketone-carboxylic acid or a corresponding diketone, and condensing the latter with at least 1\ba1/2\be mols. of the anhydride.  Suitable condensing agents are aluminium halides such as aluminium chloride or ferric chloride; these condensing agents may be used in presence of an alkali halide, such as sodium or potassium chlorides or both, or of a solvent or dispersing agent such as benzene, trichlorbenzene, chlornaphthalene, or nitrobenzene.  The products may be converted to their leuco derivatives, such as their leuco-sulphuric acid esters, and are in part dyestuffs dyeing cotton strong reddish-yellow shades and dyeing and printing vegetable fibres, and in part intermediates. In examples, fluoranthene and monophthaloylfluoranthene are each melted with phthalic anhydride and aluminium chloride, and the product obtained from fluoranthene is chlorinated, using sulphuryl chloride, or brominated, and in another example, vatted and used to dye cotton. Specification 378,476 is referred to.

Title: Improvements in or relating to the treatment of union or mixed fabrics
IPC: D06P3/82
Filed: 1921-02-09
Abstract: The cellulose acetate portion of mixed or union fabrics is dyed by means of the non-sulphonated or mono-sulphonated dyes containing "active" groups defined in Specification 182,830, and the non-acetate portion of the fabric (cotton, linen, cellulose-silk, wool, &c.) is dyed with direct, acid, mordant, or other dyes appropriate thereto. The acetate portion may be dyed first and the other portion subsequently, or vice versa; or a single bath may be employed containing both the dye for the acetate portion and that for the other portion; or one of the dyes suitable for dyeing the acetate portion and having also affinity for the non-acetate portion may be used alone.  Salts such as magnesium, zinc, or stannous chloride, may be added as in the process of the prior Specification.  The dyes may be selected so as to give a uniform shade on the fabric, or different shades on the acetate and other portion.  According to examples, a union fabric of cotton and cellulose-acetate silk is first worked in a bath of a benzidine dye to dye the cotton portion, and the acetate portion is then dyed in a bath containing insoluble Induline in suspension and acetic acid; the order of the operations may be reversed; a fabric consisting of tannin-mordanted cotton (measured or not) and acetate silk is dyed with Fuchsine.  A foam bath may be employed if desired.

Title: Improvements in or relating to starting circuits for electric motors
IPC: H02P1/12
Filed: 1951-03-01
Abstract: 700,921. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and BRYER, R. F. Feb. 26, 1952 [March 1, 1951], No. 5005/51. Class 38(3) Relates to the starting operation of unpolarized synchronous motors of the single or polyphase types, it being possible for the motor to be locked into synchronism in two modes which differ in respect of the instant during the cycle of the alternating-current at which a given point on the armature passes a particular point on the field system. Since the motor may drive periodic contacts the operation of which must occur at a particular instant in the cycle of the alternating-current, it is necessary that the motor functions only in a particular one of the two modes. The motor A is supplied from an A.C. source B across which are connected a rectifier C, relay D/1, and motoroperated contacts E which are opened and closed during alternate half-cycles of the supply voltage when the motor is running at synchronous speed. A rectifier F increases the release time of the relay D/1. The motor is started by closing relaycontacts G1 which are associated with contacts G2, the release time of the relay D/1 being sufficient to prevent opening of contacts D1 before the motor reaches synchronous speed, despite opening of contacts G2. If the motor operates in the desired manner upon reaching synchronous speed, the contacts E are closed during the half-cycles in which the rectifier C conducts so that the relay D/1 remains energized. If the motor operates in the undesired manner, the contacts E are open during the conductive half-cycles of the rectifier C, the relay D / 1 opening and the motor decelerating until the contacts E are re-closed for periods sufficient to allow re-energization of the relay D/l. The motor speed thus continues to be decreased and increased until the motor operates in the desired mode. If the motor is of the split phase type, having windings connected by a capacitor, Fig. 2 (not shown), the contacts D1 are connected in series with a resistor across the capacitor so that deenergization of the relay D/1 causes closure of the contacts D1 to decelerate the motor. Specification 679,963, [Group XXXVIII], is referred to.

Patent GB-497778-A (GB)
Title: Antioxidants for rubber
IPC: C08K5/18
Filed: 1938-02-18
Abstract: The deterioration of rubber with age is retarded by the addition of a secondary furfuryl aryl amine.  The compounds of the present invention possess the general formula R-NH-R1, where R is a furfuryl group and R1 is an aromatic group which may be substituted or not. The alpha furfuryl compounds are the preferred form, but the beta compounds are also included. The substituent group in the aryl nucleus may be alkyl such as methyl, propyl, butyl, or allyl, or halogen such as bromine or chlorine, or amino, particularly secondary amino.  However, strongly acidic groups such as sulphonic, carboxylic, or nitro groups are excluded as these tend to diminish the anti-oxidant action.  In an example, alpha furfural is added to an alcoholic solution of para amino phenol.  The crystalline material which is obtained on cooling is hydrogenated at 75 DEG  C. under a pressure of 100-150 atmospheres to give alpha furfuryl para amino phenol. Other amines which may be used include aniline, para phenetidine, ortho toluidine, the AR tetrahydronaphthylamines, ortho amino phenol, xylidine, tolidine, ortho and para anisidine, para chlor aniline, alpha and beta naphthylamine.  In addition beta furfural may be substituted for alpha furfural.  The efficiency of the anti-oxidants is shown in tabular form using a standard rubber mix.ALSO:The deterioration of rubber with age is retarded by the addition of a secondary furfuryl aryl amine.
