Abstract: 453,547. Water -gas generation. WINTERSHALL AKT.-GES., 139, Hohenzollernstrasse, and SCHMALFELDT, H., 15, Bergstrasse, both in Cassel, Germany. Nov. 2, 1935, No. 30361. Convention date, Nov. 26, 1934. [Classes 55 (i) and 55 (ii)] In the production of water gas, or gas for benzine synthesis by the gasefication of pulverulent fuel in a gasefier a by circulating gas pro. duced in the process and heated in a heater n wherein the discharged gas is utilized to pre-dry the original fuel fed into the gas stream from a hopper e. the drying gas is charged with the completely or partly gasefied dust. The drying gas issues from the gasefier at a temperature of 500-900‹ C. Mechanical disintegrating means may also be used and the coal dust is then separated from lumps in a cyclone g and an electric dust separator k before its admission at b into the gasefier. Part of the dust is continuously withdrawn at t to prevent undue accumulation of ash in the cycle. The gas discharged from the separators is cooled and freed from dust in a washer l by means of water or a coal dust suspension in water, part of the gas then being collected at p and the remainder left in the circuit. Powdered coal. charcoal, lignite and peat may be gasefied and the gasefication temperature is specified as 700-1600‹ C. In a modified method of working, the heater n is replaced by one or more regenerators heated by combustion gas and hot air, the latter being obtained from an air heater heated by the combustion of coal dust separated from the main circuit.

Wedging and jamming. - An oscillating disc valve of the kind having a pair of valve members adapted to co-operate with oppositely disposed parallel seats and carried by an internal arm, is provided with actuating mechanism which first brings the valve members opposite their seats and then acts to wedge them firmly in contact. In the form shown in the Figure the valve members 4 have central cylindrical extensions 4a loosely engaging a carrier loosely pivoted on the actuating spindle and comprising side members 5 joined by a cross piece 7. The actuating lever 8 is secured to a spindle 6, rotated by an external hand lever 15 and in opening the valve engages the cross piece 7. When closing the valve the free end 8<a> of the lever 8 engages one arm 10<a> of a bell crank pivoted to the valve carrier 5 and having the other arm 10 adapted to engage a rib 11 on the casing to prevent relative movement of the lever and carrier. When the valve members are opposite their seats they rest on ribs 12 and the end 10 of the bell crank passes in a recess 1<b> and allows a wedge surface on the lever to pass between rounded surfaces on the projections 4<a> and so press the valves to their seats. Ribs are provided on the casing to guide the valve members.

Title: Process for the purification of dimethyl formamide by distillation
IPC: C07C233/00
Filed: 1953-11-06
Abstract: Dimethyl formamide is freed from impurities such as dimethylamine and ammonia by adding to the impure dimethyl formamide, in the proportion of up to 20 per cent by weight thereof, one or more aromatic hydrocarbons having a lower boiling point than that of dimethyl formamide, and subjecting the mixture to fractional distillation under normal or reduced pressure, whereby the impurities distil over together with the added hydrocarbon.  The dimethyl formamide is then distilled over in vacuo.  Benzene, toluene and xylene are suitable aromatic hydrocarbons.  Light benzines may also be added.  In an example, benzene (6 parts by volume) and a light benzine boiling between 80 DEG  and 90 DEG C. (4 parts) are added to crude dimethyl formamide (90 parts), and the mixture is fractionated.  The amine fractions contained in the dimethyl formamide, together with traces of water, pass over in admixture with the benzene and light benzine in the fraction which first distils.  The pressure is then reduced and the dimethyl formamide which thereafter distils is completely pure, and can be employed as a solvent, e.g., in the spinning of polyacrylonitrile.

Abstract: The invention comprises dyes and their chromium complexes which in their metal-free form are of formula <FORM:0834270/IV(c)/1> where X is H or the residue of a sulphonamide group which may be N-substituted by alkyl, hydroxy-, alkoxy- or cyclo-alkyl, aralkyl or aryl groups free from COOH or SO3H groups, and R is the residue of 1-(51,61,71,81-tetrahydro-11) -naphthyl - 3 - methyl - 5 - pyrazolone - 41 - sulphonamide which may be N-substituted as in X and also by a morpholide group. They are made by conventional diazotizing and coupling methods from appropriate anthranilic acids and pyrazolones and, if desired, with subsequent chroming in substance or on the fibre. Coupling is preferably effected in an alkaline medium.  The metal-free dyes dye wool by the single bath chroming or after-chroming process in yellow shades and the complexes dye wool, silk, leather and artificial nitrogenous fibres, e.g. polyamides, also in yellow shades.

Abstract: 647,543. Enamelling. POOR & CO. Nov. 24, 1947, No. 31106. Convention date, Jan. 12; 19140. [Class 56] Ferrous metal surfaces are coated by first: preparing a glass batch containing Fe and/ or Cu molybdates, smelting, fritting, and applying the frit to the metal surface and firing at a temperature above the fusing point of the vitreous material and below the critical temperature of the metal. The composition, in parts by weight, of two glass batches with which the invention may be used are, (1) Feldspar 27.3, Borax 31.1, silica 7.0, metopax (sodium zirconium silicate) 3.0, soda ash 7.5, soda nitrate 0.7, calcite 1.05, fluorspar 4.00, cryolite 5.45, litharge 9.65, sodium silico fluoride 1.70. titanium dioxide 1.20, bone ash 0.35, sodium antimonate 0.125, and (2) boric acid 9.4, sodium silica fluoride 10.4, litharge 44.8, barium carbonate 15.55, silica 13.2, and zinc oxide 4.7. The molybdates must be smelted into the glass and examples of suitable copper and iron, colybdates, thiromolybdates, and polymolybdates are given, the polymolybdates being prepared by precipitation from solution or by a dry method, e.g. cupric polymolybdate may be prepared by boiling a neutral solution of a cupric salt with molybdic oxide, or by mixing and' heating molecular quantities of cupric and molybdic oxides. The glass is mixed and smelted at approximately 2000‹F., fritted and ground with clay water and colour to give 0-25 per cent or preferably 3-7 per cent residue on a 200 mesh. The metal articles are first cleaned, rinsed, pickled, in acid, rinsed, neutralized preferably in a warm bath containing sodium carbonate and borax, and dried. Firing below the critical point, i.e. below 750‹C. for steel,. prevents the setting up of strains and warpage in the metal. The Specification as open to inspection under Sect. 91, comprises also the use of sulphides of molybdenum, lead molybdate, and molybdic acid as bonding compounds, and the application of the molybdate, (a) as a mill addition to the glass, (b) by immersing the metal in an aqueous solution of a soluble molybdate, e.g. ammonium molybdate, (c) by first spraying the metal with a glass slip containing molybdenum and, without drying, applying a full coat of a glass containing no molybdenum, and (d) by milling an insoluble molybdate with a suspending agent such as clay with sufficient set-up agent, e.g. borax, ammonium carbonate, magnesium sulphate, magnesium carbonate, sodium aluminate, or sodium nitrate, to form a suspension of the molybdate which is sprayed on to the object before the application of the glass slip.
