Title: Improvements in and apparatus for the manufacture and production of carbon black
IPC: C09C1/50
Filed: 1935-07-17
Abstract: <PICT:0461497/III/1> Carbon black is obtained by the partial combustion of finely divided streaming carbonaceous substances, e.g. gases, vapours, mists &c. by passing a mixture of the carbonaceous substance and a suitable oxidizing gas in a substantially non-turbulent current from a burner into a substantially closed chamber in which the flame develops without restriction.  Substances such as acetylene, methane, benzene, napthalene, anthracene and various hydrocarbon gas mixtures may be burnt with oxygen, air or chlorine.  Hydrogen may also be added to the combustible mixture. The outflow velocity is preferably 10--20 per cent above that at which the flame strikes back: the combustible mixture may be preheated thus reducing the amount of oxygen required.  The flame temperature is preferably kept below 1500 DEG  C. and preferably below 1300 DEG  C. Byeproducts in the carbon black may be removed by means of solvents or by supplying outside the flame, an additional amount of an oxidizing gas, e.g. oxygen, air, steam or carbon dioxide.  In the arrangement shown, the combustible gas mixture is led through a smooth burner tube 3 and an auxiliary gas, when used, is fed to the annular tube 8, preferably below the level of the flame.  The walls of the chamber 2 may be trickled with water from conduit 9: this prevents deposition of carbon on the walls and is stated to improve the quality and yield.  Numerous detailed examples are given.  The product may be used for the preparation of dry cells or as a filler for rubber.  Specification 317,165, [Class 90], is referred to.

Title: Improvements in and relating to the production of derivatives of glyoxylic acid
Inventor: WHITFIELD GORDON HOWARD
IPC: C07F1/00
Filed: 1955-07-15
Abstract: The invention comprises lithium derivatives of the formula R1R2NCO.CH(OLi)NR1R2, where R1 and R2 are alkyl groups.  The compounds are prepared by reacting at a moderately elevated temperature a lithium acetylide with an N : N - dialkyl - substituted formamide.  Lithium acetylides containing alkyl substituents, e.g. lithium methyl acetylide and lithium butyl acetylide, may also be used.  The reaction is preferably carried out in the presence of a non-aqueous liquid medium having a boiling point in the neighbourhood of 100 DEG  C. (e.g. toluene).  The lithium derivatives may be hydrolysed to give compounds of the formula R1R2NCO.CH(OH)NR1R2.  The latter compounds may be treated with an acid (e.g. alcoholic picric acid) to give a salt of an amine of the formula R1R2NH together with an N : N - dialkyl - substituted glyoxylamide or a hemi-hydrate of an N : N-dialkyl-substituted glyoxylamide when water is present during the treatment with acid.  The compounds of the formula R1R2NCO.CH(OH)NR1R2 may also be reacted with phenyl, nitrophenyl or dinitrophenyl hydrazines to give the corresponding hydrazones of the formula R1R2NCO.CH : NNHPh.  Similarly, reaction with semicarbazide hydrochloride yields the corresponding semicarbazone.  The Specification describes the preparation of lithium derivatives of the formul  (CH3)2NCO . CH(OLi)N(CH3)2 and (C2H5)2NCO . CH(OLi)N(C2H5)2; hydrolysis products of the formul  (CH3)2NCO.CH(OH)N (CH3)2 and (C2H5)2NCO .

Patent GB-448740-A (GB)
Title: Improvements in or relating to the manufacture of laminated articles
IPC: C03C27/10
Filed: 1935-07-22
Abstract: A plastic material for use as an interlayer in laminated articles, e.g. laminated glass, comprises 100 parts of an organic ester of cellulose and as plasticizer therefor 66--150 parts, preferably 80--100 parts of a polyhydric ether alcohol in which all the hydroxy groups are esterified by a saturated fatty acid containing from 3--5 carbon atoms.  In a modification, the plasticizer is in part replaced by a second plasticizer having a greater solvent action on the cellulose ester; in this case the amount of second plasticizer does not exceed 50 parts.  Examples of suitable esters of polyhydric ether alcohols are the esters of propionic, n-butyric, iso-butyric, n-valeric, or iso-valeric acid with diethylene glycol, glycerol ethers, pentaerythritol, sorbitol, trimethylol propane, triethylene glycol, dipropylene glycol, or dibutylene glycol.  Among suitable second plasticizers which may be used, the following are mentioned: tripropionin, dimethoxyethyl phthalate, dimethoxyethyl adipate, diglyceryl tetracetate, triacetin, dimethyl phthalate, methyl phthalyl ethyl glycollate, cyclohexyl methyl adipate, and ethyl paratoluene sulphonamide.  In making the interlayer plastic sheets, any volatile solvent may be used, e.g. acetone, methyl ether of ethylene glycol, dioxane, or ethyl lactate.  In an example, a composition comprising cellulose acetate, diethylene glycol dipropionate, denatured alcohol, and acetone is mixed, rolled, and blocked, and from the block are cut the interlayer sheets.  After seasoning, the sheets are placed between glass plates and subjected to pressure at 200 pounds per square inch at a temperature of 145 DEG C.  In other examples, the plasticizers (or mixtures of plasticizers) employed are (2) diethylene glycol dipropionate and dimethyl phthalate, (3) diethylene glycol di-isobutyrate, (4) and (5) diethylene glycol di-isobutyrate and dimethyl phthalate, (6) diethylene glycol di-isobutyrate and dimethoxyethyl adipate, (7) diethylene glycol di-isobutyrate and dimethyl phthalate, (8) diethylene glycol di-isobutyrate and diglyceryl tetracetate, and (9) diethylene glycol di-propionate and diethylene glycol di-isobutyrate. The polyhydric ether alcohol esters used are prepared by reacting the fatty acid with the polyhydric ether alcohol at a high temperature, or in the presence of a catalyst and/or solvent such as toluene or ethylene dichloride.  The esters may also be prepared by ester interchange or by reacting a salt of the fatty acid with the chloride of the polyhydric ether alcohol.

The carbon diaphragm 2 is separated from a protective sheetmetal diaphragm 8 by a spacing-ring 9 of copper foil connected to the terminal 10. A mica cr paper spacing-ring 7 is preferably cemented to the diaphragm 2 and block 1 behind which is a sheet 5 of copper foil backed by a sheet 4 of rubber and connected to the terminals 6. There may be one or two diaphragms, and in the latter case cavities, 12 may be formed on both sides of the carbon block, or they may extend from side to side of the block. The current may then pass from the block to the two diaphragms in parallel, or alternatively from one diaphragm to the other, the block being of insulating-material in this case. The microphone may be arranged within a parabolic horn. The pellets are geometrically arranged in one or more cavities 12 so as to ensure a definite number of contacts and hence a constant mean resistance. ThÚ pellets may be equal spheres forming a cone or a triangular or square pyramid, the cavities 12 being correspondingly shaped, or there may be spheres of two sizes arranged in a cylinder. Numerous small pellets are used when high sensitivity is required; in other cases a smaller number of pellets with a thick diaphragm is sufficient.
