Title: A new derivative of toluene-3:4-dithiol and methods of preparation and use thereof
IPC: G01N31/00
Filed: 1957-03-20
Abstract: The invention comprises the zinc complex of toluene-3,4-dithiol containing one zinc atom combined with one dimercaptanic residue and its adducts with organic bases such as pyridine or ethylene diamine. The complex may be made by adding dithiol to a solution of zinc acetate.  Dithiol may be liberated from the zinc complex or adducts and used to detect and estimate metals with or without the addition of hydrogen sulphide.ALSO:The invention comprises the zinc complex of toluene-3,4-dithiol containing one zinc atom combined with one dimercaptanic residue, and its adducts with organic bases, from which dithiol may be liberated, for use in the detection, estimation, separation and purification of metals and their compounds.  In aqueous solution dithiol, and in some instances its zinc complex, form highly coloured complexes with thiophilic metals.  Liberation is effected by treating the complex with hydrochloric acid in alcoholic solution or with a little sodium hypophosphite in 2N-sulphuric acid solution, the dithiol being extracted by means of ethylene chloride. Standard solutions of dithiol may be prepared for volumetric analysis.  The use of the complex, as a source of dithiol, has the advantage that reactions may be effected in acid and alkaline media. Precipitates are also obtained from solutions of metal compounds in aqueous pyridine.  Complexes of the following metals are described:-palladium (ii), tellurium, gold, tungsten (vi), rhenium (vii), osmium, rhodium, arsenic, iridium, ruthenium, germanium, copper (i) and (ii), mercury, silver, antimony, tin, molybdenum, platinum, bismuth, cobalt, lead, cadmium, thallium, nickel, zinc, iron (ii), gallium, indium, manganese and vanadium.  Examples illustrate detection, estimation, separation and purification processes applied to certain of the above metals and their compounds and the purification of sodium chloride from potassium compounds, magnesium sulphate from heavy metals, bismuth chloride from tellurium and the removal of iron, nickel, copper and cobalt from sodium or potassium carbonates, barium, sodium or potassium hydroxides and di- or tri-sodium or potassium phosphates.ALSO:The zinc complex of toluene-3,4-dithiol in which one atom of metal is combined with one dimercaptan residue, from which toluene-3,4,-dithiol may be liberated, is used as an ore dressing prior to flotation.

Title: Improvements in or relating to photo-cathodes
Inventor: SCHAGEN PIETER
IPC: H01J29/38
Filed: 1963-08-20
Abstract: 1,092,094. Electron multipliers; image converter tubes. MULLARD Ltd. July 7, 1964 [Aug. 20, 1963], No. 32939/63. Heading H1D. A photo-cathode for an image intensifier or converter tube includes a matrix of insulating material in the form of a plate having an array of channels, each containing a conductive insert, extending between its two faces, the plate being covered on its input face with photoconductive material which contacts the conductive inserts and is itself covered on its exposed face by a transparent conductive layer, the opposite end of each of the conductive inserts being covered by a separate photo-emissive element, and the corresponding output face of the matrix supporting a conductive layer which is apertured in alignment with the inserts, and acts as a grid spaced from the photo-emissive elements. When the grid is maintained positive with respect to the transparent conductive layer, and when an optical image is focused upon the latter and a flooding or scanning beam is incident upon the photo-emissive elements, the density of photoemitted electrons issuing through the grid is modulated by the photoconductive effect of the incident image. The photo-cathode of Fig. 2 is formed by an arrangement of fine glass tubes 16 bonded together and containing copper wires 17, the lead oxide/lead sulphide photoconductive layer 13 being coated with a transparent aluminium layer 11. The other ends of the wires 17 are etched back and coated with photoemissive gold elements 14, which are subjected to ultra-violet flooding radiation F, the aluminium layer 15 on the tubes 16 forming the grid. The photo-cathode may be employed in an image intensifier (Fig. 3, not shown), or in a camera tube (Fig. 4, not shown), in which the photo-emissive elements are scanned by a flying spot, and the emitted electrons are received by an electron multiplier. To improve resolution, layer 13 may be constituted by a plurality of discrete elements. The glass/metal matrix may be prepared either by first bonding together by heat the tubular glass fibres-which may be coated with glaze- and then introducing molten metal by capillary action, or by first forming metal-filled glass tubes by passing tungsten wire through molten glass, and then drawing down the tubes to produce fibres, which are subsequently cut into lengths and bonded together.
