Abstract: 1,128,462. Measuring flexibility electrically. UNILEVER Ltd. March 10, 1966 [March 12, 1965], No. 10513/65. Heading G1N. The flexibility of a thin layer, e.g. of plastics material, rubber, or skin, is determined by subjecting a portion of the layer to vibration by means of column of air and measuring the amplitude of the resulting vibrations of the layer. The open end of a tube is placed in contact with the layer and the air within the tube is vibrated by means of a bellows connected to a motor and coupled to the closed end of the tube by means of a pipe. A flexible leaf spring is supported inside the tube so that its free end rests lightly on the surface of the layer and vibrates with it. Vibrations of the spring are sensed by means of a Piezoelectric element supported thereon. The amplitude of vibration of the air column may be varied by means of an air bleed at the outlet of the bellows, or by adjusting the stroke of a crank through which it is driven. The device is calibrated by placing the open end of the tube over a rotating cam.

Title: Improvements in the manufacture and production of condensation products of the anthraquinone series
IPC: C09B6/00
Filed: 1930-04-03
Abstract: 2.1 - Dianthrimide derivatives.-A 1 - amino-2-halogenanthraquinone in which both of the hydrogen atoms of the amino group are replaced by the carbonyl groups of an aromatic dicarboxylic acid capable of forming a monomolecular closed-ring anhydride, is condensed with a 1-aminoanthraquinone to give a 1-aroylimino-2.11-dianthrimide. Suitable aromatic dicarboxylic acids are phthalic acid, naphthalic acid, naphthalene-1.2- and 2.3-dicarboxylic acids and derivatives thereof.  The saponification of these products is effected by means of ammonia, or its substitution products, or similar agents having a mild action, such as alkali-metal phenolates: such agents split off the dicarboxylic acid whereas strong acid or alkaline saponifying agents do not react in the same way.  The resulting 1-amino-2.11-dianthrimides are readily condensed by known methods to form N-dihydro-1.2 : 21.11-anthraquinoneazine dyestuffs.  The above 1-aroylimino-2-halogenanthraquinones may be prepared by heating the dicarboxylic acid anhydrides with 1-amino-2-halogenanthraquinones preferably in the presence of agents accelerating the reaction, such as zinc chloride, phosphorus pentachloride, and ferric chloride.  In examples 1-phthalimino-2-bromanthraquinone is condensed with (i) 1-aminoanthraquinone; the product, 1-phthalimino-2.11-dianthrimide, is hydrolysed by boiling with 20 per cent ammonia or by heating with potassium phenolate in nitrobenzene; (ii) 1-amino-5-benzoylaminoanthraquinone; (iii) 1 - amino - 4- methoxyanthraquinone; (iv) 5.51-diaminodiphthaloylcarbazole (2 mols. to 1) (prepared by warming 5.51-dibenzoylamino-1.11-dianthrimide in chlorsulphonic acid and saponifying the product by means of sulphuric acid); (v) 1-amino-3-chloranthraquinone; (vi) 1-amino-3-benzoylanthraquinone; (vii) 1-aminoanthraquinone-3-carboxylic acid ethylester and the product saponified by heating with hydrazine hydrate in nitrobenzene to give 1-amino-2.11-dianthrimide-31-carboxylic acid ethylester; (viii) 1-amino-4-p-toluidoanthraquinone and the product saponified by heating with ethylenediamine hydrate in nitrobenzene to give 1-amino-41-p-toluido-2.11-dianthrimide; (ix) 4.41-diaminodiphthaloylcarbazole (2 mols. to 1) and the product saponified by heating with hydrazine hydrate in nitrobenzene. 1-Amino-3-benzoylanthraquinone is prepared by eliminating the amino group from 1-bromo-4-aminoanthraquinone-3-carboxylic acid, treating the product with thionyl chloride, condensing the acid chloride with benzene in presence of aluminium chloride and subjecting the 1-bromo-3-benzoyl derivative to the action of ammonia under pressure.
