Title: Electrochemical peroxydisulphatesprodn using diaphragm cell
IPC: C25B1/28
Filed: 1970-04-16
Abstract: Electrolyser used has diaphragm separating anode and cathode chambers. Cathode cycle is formed by flowing H2SO4-bisulphate soln. and anode cycle by circulating sulphate-peroxydisulphate soln., which is electrolysed at highest possible current concentration, free (partly) from peroxydisulphate outside cell in usual manner, and then returned to anode chamber.

Title: Filter matting - from layers of thermoplastic fibres with a needled bonding and heat treatment
Inventor: BERGWEILER KARL
IPC: D01D5/42
Filed: 1970-08-04
Abstract: The filter matting of curled synthetic fibres is developed by a basic layer needled to a lattice weave, and subsequent layers overlaid and needled to cause the fibres to pass from one layer to another. The bond is intensified by heat action on the thermoplastic fibres, and the use of a chemically neutral bonding agent. The fibres are extruded in fibre form, or split with an angular cross section from extruded film. The purpose is to provide a filter which is resistant to water, oil and light, which will allow water to pass through but which will retain fine particles.

Title: Converter support on carrier ring - is effected on flat surfaces obviating its lifting out on removal
IPC: C21C5/46
Filed: 1970-12-23
Abstract: The converter is fitted on its circumference with two sets of support elements consisting of >=3 elements each. One set is below and one above the level of the horse shoe shaped support ring. The distance of corresponding elements on the converter form each other > the relevant horse shoe support dimension. This is because its upper surface is fitted with several support plates for the upper converter support elements, and the lower side is fitted with closures which bridge the gap between the lower face of the support ring and the lower converter support elements, on which they rest. Pref. a pillar is fitted into the ring, which protrudes downwards onto the converter support claw and can be vertically displaced slightly by horizontal movement of a locking lever which attaches it to the ring. The system permits removal of the converter from the rings with nearly no lifting of the converter being necessary.

Title: Annealing of metal ribbons - esp the economic annealing of zinc ribbon
IPC: C21D9/68
Filed: 1971-01-13
Abstract: Metal ribbon, partic.
