    摘要: Metal values, especially copper values, are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by a 1,2,4 triazole substitued in the 1- position by (1) a hydrocarbyl (alkyl) group or (2) a group of the formula --(X).sub.n --(CO--Y).sub.m where X is an optionally substituted methylene, vinylene or phenylene linking group or a linking group of formula --CO--A-- where A is an optionally substituted aromatic ortho linking group; n is 0 or 1; Y is OR.sub.2 or R.sub.3 where R.sub.2 and R.sub.3 are hydrocarbyl groups containing from 5 to 36 carbon atoms (preferably branched alkyl groups containing from 9 to 24 carbon atoms); and m is from 1 to 3.

    摘要: A dye ribbon cassette for thermal transfer printing comprising a casing containing bearing means having rotatably mounted thereon a cylindrical member having on its periphery a mark carrying information capable of being detected by a sensor on rotation of the member and means operatively engageable with a drive source which is disposed outside of the casing to cause rotation of the member. The cassette may include a pair of identical, spaced apart, shafts rigidly mounted at one end of the casing, one of the shafts forming the bearing means for the cylindrical member, the shafts forming respectively mounting points for a feed spool and a take up spool.
