Title: Improvements in the production of aromatic carboxylic acids, their esters and salts
IPC: C07C63/00
Filed: 1956-10-10
Abstract: Aromatic carboxylic acids, their esters or salts, are made by reacting a halogen-substituted aromatic hydrocarbon which may be further substituted by carboxylic acid or ether groups with at least the equivalent amount of a formate of an alkali or alkaline-earth metal or of ammonium or of a mixture thereof, or a corresponding quantity of the corresponding hydroxide and carbon monoxide, at elevated temperature and under increased pressure, the reaction being conducted in the presence of an alcohol if the ester is desired or of a basic-reacting compound if the salt is desired.  The reaction may be conducted continuously or discontinuously by heating the mixture of halogen compound and formate in a closed vessel, if desired in the presence of nitrogen or carbon monoxide.  When hydroxides are used a portion of the hydroxide may be replaced by the corresponding carbonate. Catalysts comprising metal carbonyl compounds such as carbonyl compounds of nickel, cobalt, iron, molybdenum and chromium, metal carbonyl hydrides such as that of cobalt, or compounds of the formul  Fe(CO)4Br2, (R3P)2Ni(CO)2 or (R3P)Ni(CO)3 where R is a hydrocarbon radical such as alkyl, may be used.  When a pressure of carbon monoxide is used the carbonyl-forming metals themselves may be used as catalysts.  Other catalysts are copper or silver metals and halides of copper, silver, nickel, cobalt and iron. Halogen-substituted aromatic hydrocarbons mentioned are mono- or poly-halogen substituted benzene, toluene, xylene, diphenyl, naphthalene or anthracene or mixtures thereof.  Alkali or alkaline-earth metals specified as formates or hydroxides are sodium, potassium, magnesium, calcium, barium and strontium. Alcohols for use in obtaining esters are methanol, ethanol or propanol. Basic-reacting substances for use in obtaining salts are oxides, hydroxides, carbonates or salts of weak organic acids and alkali or alkaline-earth metals, ammonia, alkylamines, pyridine or quinoline. Examples 1 to 7 illustrate the preparation of terephthalic acid from p-dichlorobenzene under various conditions, p-chlorobenzoic acid being sometimes obtained as a by-product; other examples illustrate the making of (8) 4 : 41-diphenyl dicarboxylic acid from 4 : 41-dichlorodiphenyl, (9) terephthalic acid and bromobenzoic acid from p-dibromobenzene, (10) o-phthalic acid from o-dichlorobenzene, (11) disodium terephthalate from p-chlorobenzoic acid, (12) anisic acid from p-chloroanisole, (13) dimethyl terephthalate and terephthalic acid from p-dichlorobenzene and methanol, and (14) disodium terephthalate and sodium chlorobenzoate from p-dichlorobenzene in the presence of soda.

Title: Improvements in or relating to the disinfection of insect-infested food such as fruit, grain or other starchy products, wearing apparel such as furs, woody materials or tobacco
IPC: A23B9/02
Filed: 1937-11-11
Abstract: 511,179. Treating grain. GUARDITE CORPORATION. Nov. 11, 1937, Nos. 30994 and 30995. Convention dates, Nov. 11, 1936, and Feb. 19, 1937. [Class 58] [Also in Group VI] Insect-infested grain is disinfested by evacuating to remove substantially all non- condensible gas from the grain and passing in steam to produce a temperature within the range of not materially below 100‹F. to 130‹F. and maintaining the temperature within this range at least until the grain is free from insect infestations, a period of about 20 minutes at 100‹F. being necessary for disinfection, and smaller periods at higher temperatures. The steaming period may however be continued beyond that necessary for disinfection if it be desired to establish a certain final moisture content in the grain. The grain, e.g., wheat, may be moistened before evacuation and may be introduced into the evacuation chamber at say 79"F. or 85‹F. Evacuation is such that the moisture in the grain boils at the prevailing temperature, and the vapour drives the non- condensible gas from the grain. Specification 488,638 is referred to.

Title: Method of producing magnetic materials
IPC: H01F1/06
Filed: 1950-12-20
Abstract: In a method of producing magnetic materials to which a high permeability may be imparted, the entire operation of melting the ingredients of the material is conducted with the melt under cover of a carbon-containing reducing slag and the melt is then formed into a solid body from which carbon is removed by heat treatment in hydrogen, e.g. for at least one hour at a temperature between 1100 DEG C and the melting point of the material.  The melt is preferably kept substantially free from deoxidizers such as Ca, Si, Mg and Al but a small proportion, e.g. 0.2-2.0 per cent of Mn may be added to prevent gassing during solidification.  After decarburization the material may be submitted to a relatively low temperature heat treatment to develop its optimum magnetic properties.  The treatment of the following alloys is referred to: Ni 75-85 per cent, Mo 2-7 per cent, Mn up to 2 per cent, Fe and impurities, the remainder; soft iron; Fe-Si alloys; Fe-Ni alloys; Fe-Ni-Cr alloys; Fe-Ni-Cu alloys; Fe-Ni-Mn alloys; Fe-Ni-Co alloys; and Fe-Co-V alloys.

Abstract: 1,157,208. Measuring physical properties electrically. AUTOMATION PRODUCTS Inc. July 6, 1967 [July 22, 1966], No. 31137/67. Heading GIN. Physical properties of a material are measured by their effect on the amplitude of vibration of a member which is contacted by the material, e.g. a U-tube member 12a, Fig. 2, carrying a test liquid, the member being mounted resiliently in a support 14a for vibration about the support 14a, and carrying vibration producing means 18a and vibration measuring means 26a in an assembly which is resiliently mounted by springs 36a on the member at a position spaced from the support 14a. The natural frequencies of the assembly and of the springs are arranged to be appreciably higher than the natural frequency of the complete apparatus about the support 14a, to exclude the effects of environmental vibrational influences present in the support 14a. The vibrations are produced by an A. C. energized solenoid 18a, (18, Fig. 1, not shown) and measured by an inductive transducer 26a (26), the vibrations being transverse to the plane containing the U-tube 12a, or parallel to the axis of an open ended hollow cylinder (12b, Fig. 4, not shown) which extends downwards into a container for the material under test. The cylinder (12b ) is resiliently supported (at 16b ), and contains vibration producing (18b) and measuring (26b) transducers which are supported as an assembly (34b) on a spring (36b) attached to the closed end of the cylinder. Preferably the vibration producing and measuring assemblies of both embodiments have greater mass than the vibrated member 12a (12b) so that the assemblies remain substantially stationary. The properties which may be measured include mass, viscosity, density, specific gravity and (Fig. 4) material interface.
