Title: Per:fluoroalkane-sulphonyl fluoride prepn. - by electrolysis of alkane-sulphonyl halide or sulphone in hydrogen fluoride
Inventor: WECHSBERG MANFRED DR
IPC: C25B3/28
Filed: 1977-06-03
Abstract: Prodn. of perfluoroalkanesulphonyl fluorides (I) is carried out by electrolysis of a soln. of an alkanesulphonyl halide and/or a cyclic unsatd. sulphone in practically anhydrous HF. The improvement comprises (a) using anodes whose surface has been mechanically roughened (pref. by sand blasting) and (b) using an electrolyte which has already been electrolysed with a quantity of electricity of >=1 Ah per cc of electrolyte and/or which has already produced 0.05 g of (I) per cc of electrolyte. Cpds. (I) are useful as intermediates for preparing repellents ("phobiermitteln") and surfactants. The improvement shortens the induction period for (I) prodn., which increases yields, improves current efficiency and reduces the risk of explosions during start-up, and allows used electrolyte to be recycled, which reduces material losses and avoids pollution problems.

Title: Powder metallurgy workpieces prodn. system - in which carbon is added as necessary between annealing and compression stages before sintering
Inventor: DAIN RICHARD JAMES
IPC: B22F3/00
Filed: 1978-03-23
Abstract: The process produces metal items by heating a metal powder consisting mainly of tool, alloy or stainless steel or a high-tensile metal alloy. The powder is produced by pulverising and water-quenching of a melt to give irregularly-shaped particles, in a vacuum of 1.0 Torr at 900 degrees C to reduce the oxygen content, followed by controlled cooling to anneal the powder. The powder is compressed into blanks of >=60% relative density, and heated in a first stage in a vacuum below the setting temp. of the powder for at least half an hour to reduce the oxygen content to 0.7%. In a second stage their temp. is increased to a sintering temp., while a vacuum or partic. atmosphere is maintained round them. Sintering continues for 0.5-4 hrs. to increase the relative density to >=93%. The items are produced to standard dimensions, giving a charge weight of >=20 kg for the blanks heated in the first two stages. Between annealing and compression the powder is analysed for C and O content, C being added as necessary. Sintering temp. is selected to suit the C content, being maintained constant within +10 deg. C during sintering.
