Title: Aluminium organic complexes and their use in treating leather
IPC: C14C3/02
Filed: 1960-01-13
Abstract: An hydroxy aluminium salt is obtained in alcoholic solution by reacting concentrated hydrochloric acid with a solution of aluminium isopropylate in isopropanol; by adding an alcoholic solution of caustic soda to an alcoholic solution of aluminium chloride hexahydrate or by adding ethanolic caustic potash to a solution of aluminium nitrate nona-hydrate in ethanol.  The salts which contains 33 or 66% hydroxyl are used in the preparation of aluminium-containing carboxylic acid compleexs (see Group IV(b)).ALSO:Alcoholic solutions of water-soluble aluminium containing complex salts are prepared by reacting a basic salt of aluminium, as hereinafter defined, in a water-soluble monohydric alcohol having 1-6 carbon atoms, with a solution in such an alcohol of an aliphatic carboxylic acid containing 2-15 carbon atoms, a p  cycloaliphatic carboxylic acid containing up to 15 carbon atoms, an aromatic carboxylic acid containing up to 15 carbon atoms or an aliphatic-aromatic carboxylic acid containing up to 15 carbon atoms, with 2-8 carbon atoms being in the aliphatic chain, the carboxylic acid containing at least two carboxylic acid groups or at least one carboxylic acid group and an aromatic hydroxyl or mercapto group, but not containing other substituents which react with the basic aluminium salts.  The basic aluminium salts are hydroxy aluminium salts of inorganic acids, the anions of which do not combine with the complex aluminium cation in the resulting aluminium containing complex salt to form an insoluble salt or precipitate.  Suitable basic salts are the chlorides and nitrates; the basicity preferably ranges from 33 to 66%.  The complexes comprise aluminium and the carboxylic acid in the cation, the anion being that of the basic aluminium salt.  The complexes become water-insoluble when freed of the alcoholic solvent but are resolubilised on treatment with alcohol.  The complex cation combines with sulphate ions to give an insoluble salt; carbonates, oxalates, chromates, polymeric inorganic acid salts for example, polyphosphate and phosphotungstates and the resin acid salts formed with the complex cation are also insoluble. The soluble complexes may be used as assistants in leather tanning (see Group VIII).  In examples (1) an isopronanolic solution of 66% basic aluminium chloride is reacted with an isopropanolic solution of an octyl adipic acid, dodecyl malonic acid, butane1,2,4-tricarboxylic acid, orthophthalic acid or octyl salicylic acid at an elevated temperature; (2) an isopropanolic solution of 33% basic aluminium chloride is reacted with an isopropanolic solution of o-phthalic acid.  Other carboxylic acids specified are oxalic, adipic, sebacic, mellitic, maleic and fumaric acids; substituents such as -OH, CN-, -SH or halogens may be present.

Title: Improvements in or relating to anti-ground noise sound recording systems
IPC: G11B7/00
Filed: 1938-01-15
Abstract: 500,994. Recording sound. RADIO CORPORATION OF AMERICA. Jan. 15, 1938, No. 1426. Convention date, Feb. 13, 1937. [Class 40 (ii)] In a method of recording sound on film by the variable width method, additional light is directed on to the film so as to expose a margin at the edges of the sound record, provision being made whereby the record of the sound waves is of greater density than the said margin: When a positive is printed from such a negative the whole of the track, with the exception of the record and the marginal area, is overexposed, this overexposure resulting in spreading of the image with consequent filling up of any pinholes or scratches in the dark part of the track. In the recording system light from a source 1, Fig. 1, is passed through a condenser 2, a triangular aperture plate 3 and lens 4 to an oscillograph 6 whence it is reflected through a lens 7 to a horizontal slit 9 and is focused on the film 11 by a lens 10. The triangular aperture 3<1> has semitranslucent margins on its upper edges, these margins being of material which will transmit approximately 50 per cent of light falling on them. The intensity of the light source 1 is double that normally used so that the negative consists of an extremely dense portion 15, Fig. 2, forming the actual record, which portion however, owing to the nature of the stock used, does not suffer from spreading of the image, a margin 14 of normal density and a clear portion 13. When printing is carried out, the marginal portion 16, Fig. 3, is so exposed as to be of normal density with the result that the outer part 18 is considerably overexposed so giving spreading of the image with consequent filling in of any clear portions. The Specification also describes a method, Fig. 4 (not shown), in which, in the negative, the actual sound record is overexposed as before but the normally exposed marginal portion follows the envelope of the sound waves instead of its contour. This is achieved by directing on to the film light beams from two separate sources through two separate optical systems and superimposing them. One oscillograph vibrates in accordance with the sound waves to be recorded while the other is made to vibrate in accordance with the envelope. As the effects of the two are superimposed the actual sound record receives double normal exposure, with the desired result.
