Title: Improvements in or relating to the disulphonation of benzene and the production of resorcinol therefrom
IPC: C07C309/29
Filed: 1949-01-19
Abstract: A method of preparing benzene disulphonic acids wherein the formation of side reaction products is inhibited to a substantial degree comprises reacting benzene monosulphonic acid and high strength oleum comprising from 60 to 100 per cent free sulphur trioxide at a temperature between 145 DEG  and 200 DEG  C. in the presence of from 0.01 to 3 mols. of an alkali metal sulphate, an alkaline earth metal sulphate, an alkali metal benzene sulphonate or an alkaline earth metal benzene sulphonate for each mol. of benzene monosulphonic acid. Resorcinol is prepared from the product by neutralization, purification, fusion with alkali and extraction from the acidified aqueous solution of the fused mass. Suitable alkali metal and alkaline earth metal sulphates mentioned are sulphates of potassium, calcium, barium and sodium and alkali-metal and alkaline earth metal benzene sulphonates mentioned are those of sodium and barium.  The sulphate or sulphonate may be added wholly prior to or during the monosulphonation of benzene or prior to or during the sulphonation of the monosulphonic acid.  In converting the product to resorcinol the reacted mixture is neutralized and after removal of excess sulphate salts, dried or made up as e.g. a 50 per cent solution and the solid product or solution is fused with alkali, e.g. caustic soda, the fused mass is dissolved in water and neutralized with acid and the resorcinol is extracted with a water-immiscible resorcinol solvent, e.g. isopropyl ether and recovered from the solvent.  In examples: (I) benzene is passed with oleum (65 per cent SO3) and sodium sulphate into a reactor containing a reaction product continuously circulated over the starting material inlets.  The product contains benzene monosulphonic acid and diphenyl sulphone.  Further sodium sulphate is dissolved in the product whilst heating and sulphur trioxide is added.  Stirring and heating are continued and a product containing benzene disulphonic acid and diphenyl sulphone disulphonic acid is obtained.  The reaction product is neutralized, excess sulphate is removed and sodium salts of benzene disulphonic acid as a 50 per cent solution or as dry salt are fed into molten sodium hydroxide and the mixture is heated to fusion temperature.  The mass is dissolved in water, neutralized with hydrochloric acid, the solution is extracted with isopropyl ether and resorcinol is obtained on boiling off the isopropyl ether from the extract; (II) resorcinol is similarly prepared using oleum containing 100 per cent SO3 and a lower proportion of sodium sulphate; (III) benzene and sodium sulphate are placed in a reactor to cover the inlet tubes, some oleum is passed in and then benzene and oleum together in equimolar proportions.  Further oleum is added and the temperature is raised. Resorcinol is obtained from the products as in (I).

Title: Improvements in television electron camera tubes
IPC: H01J29/39
Filed: 1944-01-26
Abstract: 584,970. Electron image tubes. WESTERN ELECTRIC CO., Inc. Jan 26, 1944, Nos. 1515 and 1516. Convention dates, Jan. 30, 1943. [Classes 39 (i) and 40 (iii)] A television electron camera comprises an apertured flat plate 50, Fig. 2, provided on one side with a mosaic of photo-voltaic cells 51 which are illuminated by the picture to be transmitted. The other side of the plate is scanned by an electron beam and the number of electrons passing through each aperture and reaching the picture signal collecting grid 14 is controlled by the average potential assumed by the cells surrounding the aperture. The electron beam may be of sufficient velocity when it strikes the plate to generate secondary electrons, as shown, which contribute mainly to the signal current; or the screen 111, Fig. 4, may be nearly at cathode potential, so that the scanning beam is nearly at zero velocity and itself provides the signal current, the whole tube being immersed in the magnetic field of coil 114 with appropriate scanning plates 116 and coils 117. In a modification, each aperture in the screen 150, Fig. 5, is surrounded and partially filled by an individual photo-voltaic cell 151. In making the screen of Fig. 2, the' apertures nickel plate 150 is insufflated with asphaltum particles which are warmed to produce a series of fine dots. The plate is then greased and silver-plated and the asphaltum dots removed. Copper is then evaporated on and the silver mask is stripped off, leaving a mosaic of copper dots. A blocking layer is formed on the copper by electron or ion bombardment and a final layer of gold evaporated over it. Such cell is of the " front wall " type, but a " back-wall " cell may also be used. In making the screen of Fig. 5 the nickel plate is dipped in wax and passed over a roller inked with acid-resisting etching ink so that the ink is squeezed through the apertures and over a small area around each aperture, and replaces the asphaltum of the previous process, which is then continued. The copper oxide cell may be replaced by one formed of silicon and silicon oxide (quartz). The silicon may be deposited from decomposing silicon hydride or a mixture of silicon tetrachloride and hydrogen ; to reduce impedance it is preferably put on in two layers of which the first contains also a conducting metal such as aluminium, arsenic, titanium, copper or silver. The quartz may similarly be mixed with tungsten, or alternate layers of tungsten and quartz may be deposited. Specifications 475,047, 482,959, 492,284, 505,618, 510,696, 539,419, 555,015, and 584,969, are referred to.
