Patent GB-217242-A (GB)
IPC: G01N7/02
Filed: 1924-06-06
Abstract: 217,242. Bock, M. M. June 9, 1923, [Convention date]. Dials and scales; index hands and pointers. - In apparatus for indicating at a distance the results of the automatic analysis of furnace gases, a ratchet m is periodically moved by a train of electric impulses whose number is proportional to the required measurement, and is returned to zero after each operation. In one form of the device a disc o is connected to the ratchet wheel m by springs shown diagrammatically at x<1>, x<2>. It is normally held by a brake u, but when the train of electric impulses has been completed this brake is momentarily released and the disc adjusts its position to that of the ratchet wheel; thus the disc only moves when there is a difference between two successive readings of the analyser. In the case where readings are taken alternately, the first of a pair giving the natural CO2 content of a sample while the second gives CO2 content when the admixed CO has been oxidized, two discs o are operated alternatelv. Both discs are cut away at their peripheries so that part of a fixed scale can be seen through the cut-away sectors, the disc for the natural samples being opaque while that for the oxydized samples is red and transparent. Hence the presence of C.O. is indicated by part of the scale being seen through a red screen.

Title: Improvements in or relating to the production of alkali metal sulphides
IPC: C01B17/30
Filed: 1936-05-25
Abstract: Alkali metal sulphides are obtained by reacting an alkali metal amalgam, derived from the electrolysis of alkali metal chloride solution using a mercury cathode, with sulphur or an alkali metal polysulphide.  The reaction may be carried out continuously in apparatus separate from or connected to the electrolytic cell, the mercury set free being returned to the cell.  Pure products may be obtained by ensuring the presence of amalgam and sulphur or polysulphide throughout the reaction, and stoichiometric ratios between the sulphur or polysulphide and the alkali of the amalgam may be maintained.  An example relates to the production of sodium sulphide using an aqueous or hydroalcoholic solution of sodium polysulphide.  The Specification as open to inspection under Sect. 91, comprises also the use, in the process, of the alkali metal derived from the electrolysis without its amalgamation with mercury using for instance cells with porous or liquid diaphragms, and includes examples of the preparation of both sodium and potassium sulphides.  This subject - matter does not appear in the Specification as accepted.
