Title: Improvements in or relating to luminescent materials
IPC: C09K11/63
Filed: 1952-05-06
Abstract: 711,094. Luminescent materials. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 6, 1952 [June 4, 1951], No. 11406/52. Class 39(1) A method of producing a manganese activated zinc borate phosphor includes the step of adding a magnesium halide, preferably the chloride or fluoride, to the raw materials necessary to form the phosphor. In an example there is added to the raw materials of the phosphor a sufficient amount of magnesium chloride, preferably fused magnesium chloride, to obtain a phosphor having in solid solution between about 0.005 to about 0.75 mole, preferably about 0.054 mole, of magnesium chloride per 3.0 moles of zinc. The same proportions are used when magnesium fluoride is employed. The phosphor can be made by using an excess of 5 per cent by weight of boric oxide over the amount required for stoichiometric proportions. In one example a phosphor is made by firing a mixture of the following ingredients by weight; zinc oxide 48.8 parts, ortho-boric acid 27.2, fused magnesium chloride 2.20 and manganous chloride 2.26. Another example includes the following ingredients by weight; zinc carbonate 75.2, boric oxide 15.3, fused magnesium chloride 2.20 and manganese dioxide 0.99. The ingredients are intimately mixed and fired for 1 to 4 hours at about 600 to 950‹C, preferably for 2 hours at 910‹C, in an open silica container, cooled and then milled until the desired particle size is obtained.

Patent GB-745070-A (GB)
Title: Improvements in or relating to basic thymol dimethyl-amino ethyl ethers
Filed: 1953-04-28
Abstract: The invention comprises basic thymol dimethylamino-ethyl ethers of the general formula <FORM:0745070/IV(a)/1> where R is a hydroxy, alkoxy or acyloxy group.  Preferably R is a hydroxy, methoxy or acetoxy group.  Such compounds are obtained by treating thymol with sodium nitrite and an acid to form nitroso-thymol, introducing the latter into ammonia, reducing with hydrogen sulphide to form 4-amino thymol, acetylating the 4-aminothymol, converting the resulting 4-acetaminothymol with dimethylaminoethyl chloride into the dimethylaminoethyl ether of 4-acetaminothymol, treating with hydrochloric acid to hydrolyse the 4-acetamino group to an amino group, making the mixture alkaline and extracting with ether, diazotizing the resulting 4-aminothymoxyethyldimethylamine, adding a small quantity of copper sulphate to the diazo compound, boiling, making the mixture alkaline and introducing carbon dioxide form 4-oxythymoxyethyldimethylamine.  The product can be acetylated with acetic anhydride and pyridine to form the corresponding 4-acetoxy compound, or methylated with diazomethane in ether to form the 4-methoxy compound.  Examples illustrate this method of preparation.
Patent GB-567774-A (GB)
Title: Improvements in or relating to processes of treating cellulosic raw material, and the improved cellulosic fibres resulting therefrom
IPC: D21C3/18
Filed: 1942-08-24
Abstract: Cellulosic raw materials are impregnated with a wetting agent and then subjected to the action of chlorous acid, a chlorite, or chlorine dioxide.  The treatment effects a bleaching of the materials and facilitates the subsequent removal of lignins, pentosans and other non-cellulosic constituents by alkali or other chemicals.  The chlorite treatment itself effects at least a partial separation of the fibres and it may be continued until there is obtained a sufficiently purified white pulp not requiring further chemical treatment.  Preferably, the material is impregnated with an acid or acid-reacting substance prior to treatment with a solution of a chlorite.  The cellulosic material may be wood, flax, or other lignin-containing cellulosic raw material, or it may be raw cotton, cotton linters, or raw cotton waste.  Wetting agents which may be used in the preliminary treatment are octyl phenols or their salts, complex condensation products of long chain aliphatic alcohols with phenols, water-soluble sulphonates of a condensation product of naphthalene and polymerized isobutylene, and tertiary alkylaryloxy alkylols. They may be added to the acidifying liquid.  In an example, raw flax fibre is immersed in a dilute solution of acetic acid containing a wetting agent.  The fibre is removed and excess liquid pressed out.  The fibre is then immersed in a hot solution of sodium, calcium, or other metallic chlorite.  It is removed from the liquid, washed, and then boiled in a solution of caustic soda.  The fibre may then be bleached with hypochlorite solution. It may be employed in paper-making or may be used for spinning and weaving, or for conversion into cellulose derivatives and products such as plastics, films, filaments and the like.  If desired, alternate treatments with chlorite and caustic soda solution may be performed on the raw material.  If removal of lignin is not essential, the treatment with caustic soda or other reagent, subsequently to the chlorite treatment, may be omitted, since the fibre after the treatment with chlorite is in a bleached state suitable for paper-making or spinning.  When chlorine dioxide is used, the cellulosic material may be wetted and then treated with a gaseous mixture of chlorine dioxide and hydrochloric acid or acetic acid vapour.  Wood chips may be cooked under pressure in water containing a wetting agent and then after washing may be cooked in an open vessel containing sodium chlorite acidified with acetic acid.  The chlorite treatment may be repeated.  The pulp obtained may be cooked with a solution of caustic soda and finally bleached with hypochlorite.

Title: Improved process for the production of chlorine
Filed: 1943-07-27
Abstract: Chlorine is prepared by contacting hydrogen chloride gas at a temperature between 400 DEG  and 1200 DEG F. (preferably from about 800 DEG -900 DEG F.) with a catalyst formed by preheating a mass containing an oxide or oxides of chromium and/or manganese at a temperature above 500 DEG F. in the presence of oxygen (e.g., by heating in air for 2-20 hours).  The catalyst may be regenerated under the same conditions as for the pretreatment.  The process may be operated with finely-divided catalyst in suspension in the gas, either as a fluidized bed, which is removed from the base of the reaction vessel, or being carried out of the top of the vessel with the gas, and then separated therefrom.  The catalyst may be prepared by adding a carrier material, such as titania gel, silica gel, kieselguhr, or pumice, to a concentrated solution of the oxides or salts of the metals and then drying.  Alternatively titania gel may be sprayed with a solution of chromium nitrate, or chromium oxide may be made into pellets with powdered ball clay. A small amount of cerium oxide may be mixed with the chromium catalyst, example 6 referring to a catalyst containing 0.6 per cent. cerium. 1.2 per cent. potassium, and 11 per cent. chromium oxide, on an alumina base. A manganese catalyst may be made by granulating pyrolusite and heating overnight to about 300 DEG F.  The Specification as open to inspection under Sect. 91 includes also the use of uranium as a catalyst, referring to impregnating a carrier, e.g., pumice or silica gel, with uranium nitrate solution, and to a composition containing 5 per cent. uranium oxide, 5 per cent. chromium oxide, and 0.5 per cent. cerium oxide. This subject-matter does not appear in the Specification as accepted.
