Abstract
278,465. British Dyestuffs Corporation, Ltd., Cronshaw, C. J. T., Baddiley, J., and Chapman, E. July 21, 1926. Clutches, friction.-In order to counteract the effect of moisture on the operative surfaces of friction clutches the surface is treated with water soluble protective colloids or wetting-out agents of the sulphonic acid class, which may either be added to the asbestos or other material forming the friction surface during the process of manufacture or may be applied to the surface subsequently. Substances which may be used, preferably in the form of their sodium salts, include the sulphonic acids of aliphatic hydrocarbons, the sulphonic acids of aromatic hydrocarbons containing an aliphatic, alicyclic, or aromatic-aliphatic side chain such as isopropyl naphthalene sulphonic acid, the sulphonic acids of hydrogenated aromatic hydrocarbons, such as tetrahydronaphthalene sulphonic acids, the sulphonic acids of condensed hydrocarbons, e.g. the condensation products of aromatic sulphonic acids and aldehydes, or lignone sulphonic acids. The products obtained by sulphonating certain petroleum fractions and condensing with isopropyl alcohol, as described in Specification 274,611, [Class 15 (ii), Dyeing, Processes &c. for], are also suitable, an example given being the sulphonating of 84 parts of the liquid sulphor-dioxide extract of Borneo petroleum with 92 parts of sulphuric acid monohydrate and condensing with 76 parts of isopropyl alcohol and 53 parts of sulphuric acid.
