Title: Artificial leather
IPC: D06N3/14
Filed: 1965-07-27
Abstract: An artificial leather comprises a base material coated or impregnated with an amino acid polymer.  The base can be of: natural fibres, e.g. cotton, cellulose, wool; synthetic fibres such as polyamide, polyester, polyacrylic, polyvinyl, polyvinyl alcohol, polyolefin fibres; inorganic fibres such as glass fibre; mixtures thereof.  The fibrous base may be woven or unwoven, or paper.  The base may also be a sheet of a resin e.g. polyvinyl chloride, or rubber, or of nylon fibre coated with polyvinyl chloride.  The polymers are formed from neutral or acidic amino acids, and lower aliphatic esters thereof, e.g. lower alkyl esters, aromatic esters of acidic amino acids, basic amino acids and acyl derivatives thereof.  Examples of neutral amino acids are: glycine, alanine, valine, leucine, isoleucine, phenylalanine, tyrosine, proline, hydroproline, serine, threonine, cysteine, cystine, methionine, tryptophan; of acidic amino acids: aspartic acid, glutamic acid; of basic amino acids: orginine, lysine and histidine.  The polymer may be applied as a solution to the base material, and solvent evaporated therefrom. Adhesives may be used to cause the polymer to adhere to the base material.  The amino acid may be polymerised after the monomer or low polymer is applied.  In example 4, a film of aspartic acid methyl ester polymer is bonded to a leather substitute comprising a nylon fibre coated with polyvinyl chloride using polyvinyl chloride paste; in example 5 the film is compressed on to a sheet of polyvinyl chloride.ALSO:An artificial leather comprises a base material coated or impregnated with an amino acid polymer.

[Class 97 (iii)] A gyrovertical for moving craft, which, in accordance with the parent Specification has its rotor spin axis normally inclined with its top end foremost in the direction of movement of the craft so that it has at least a component of inclination in a vertical plane parallel to the fore-and-aft axis of the craft, is erected by means that provide a torque that increases progressively with the increase in relative angular displacement of the gravity-responsive means and the gyro in such a manner that the indications of the instrument are unaffected for any rate of turn at a prescribed speed. As shown, the gyro 1<SP>1</SP> is erected by means of an eddy current disc 11<SP>1</SP> mounted to spin on an extension of the rotor axis which co-operates with a magnetic inductor 25 pendulously mounted about an axis 22<SP>1</SP>, as described in Specification 492,670, the desired inclination of the gyro being obtained by weighting the magnet 25 by an adjustable weight 26 so that it hangs out of the vertical by an amount corresponding to the desired angle. If desired, the gyro may be pendulously mounted and the effect of acceleration forces on the pendulousness of the gyro compensated for by giving the rotor a lateral component as well as a fore-andaft component of normal inclination. The erection rate may be varied with the air-speed so that compensation is effective at all speeds of the craft. The gyrovertical may be provided with an indicating shell 31 as in Specification 591,400. The Specification as open to inspection under Sect. 91 describes an eddy current erecting device wherein the disc is eccentrically mounted on an extension of the rotor spin axis. This subject-matter does not appear in the Specification as accepted.
