Filed: 1928-09-24
Abstract: 324,631. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 24, 1928. Paraffin and mineral waxes.-Products resembling natural waxes and suitable for use in boot and floor polishes and the like, are obtained by esterifying together, may be in presence of a catalyst, e.g. sulphuric or hydrochloric acid, montan wax bleached by oxidation and a fatty, aromatic, or hydroaromatic acid, by means of a polyhydric alcohol. Any free acids in the products may be wholly or partially converted into salts, esters, anhydrides, amides, or other -CO- compounds, or into mixtures thereof. Solid or liquid hydrocarbons, or oily, fatty, waxy, or resinous substances, containing no free -COOH- groups may be added before, during, or after the esterification. The bleached wax may be replaced by a conversion product still containing free acid, e.g. the products described in Specification 320,854, and the polyhydric alcohol by carboxylic acids, aldehydes, ketones, or phenols, containing 2 or more hydroxyl or other e.g. halogen groups capable of esterification under the conditions. For example, (1) 220 kg. of cocoanut oil fatty acids, 150 kg. of ethylene glycol, or 300 kg. of polyglycol, and 1 kg. of 40 per cent sulphuric acid are heated for about 1 hr. at 120-130‹ C., then 1000 kg. of montan wax bleached according to Specification 308,996, and consisting mainly of free acids, 100 kg. of tallow acids, and 40 kg. of wool grease are added, and the whole heafed to 120-150‹ C. for 3 hrs. The flexibility of the soft plastic product may be increased by melting with 25 per cent of its weight of paraffin wax; (2) 20 kg. of cocoanut oil fatty acids, 5 kg. of naphthenic acids, and 7 kg. of ethylene glycol are stirred for ¢ hr. at 160‹ C.; 100 kg. of montan bleached as described in Specification 305,552 are then added and the mass maintained for 4 hrs. at 120-130‹ C. The free acids in the product are then esterified by heating for another hour with 9 kg. of benzyl alcohol. The Specification also describes the use of benzoic, salicylic and wool-grease acids, castor oil, tallow, and glycerol, and of calcium and barium oxides to form salts with the free acids of the products.

Title: Improvements in gas producing methods and apparatus therefor
IPC: C10J3/00
Filed: 1922-10-10
Abstract: 204,909. Berg, E. Oct. 10, 1922. Producers.-In obtaining gas from two producers and a superheater the latter is heated by the waste gases during the blasting up period and the water gas generated in one producer is passed through the superheater and then up through the second producer which is charged with green fuel on top of the heated coke bed. The producers a, a<1> and the superheater bare connected by conduits and valves so arranged as to permit of the passage of gases in either direction through each of the units. Air from a main k is passed up through a producer a and the blast gases are admitted at the bottom of the superheater b and escape through an outlet q. Steam is then passed from a pipe n through producer a and the water-gas is led to the upper part of the superheater and after being heated is passed by a pipe d into the lower part of the producer a' rising through the coke and distilling the green fuel at'the top of the fuel bed, the resulting gases giving a high yield of low-temperature tar. Air may be supplied to the second producer to maintain the temperature therein, and the gases may be carburetted by the addition of oil through a pipe r to the superheater. Steam may be generated in the superheater for use in the process by supplying water through a pipe s. The various valves may be so coupled or combined that a change in the working may be effected by the operation of one single element.

Patent GB-493398-A (GB)
Title: Improved method of concentrating aqueous solutions, suspensions and the like
IPC: A23L2/12
Filed: 1937-10-11
Abstract: Aqueous liquids, such as natural juices, milk, extracts, and the like, are converted into liquid concentrates by first freezing out some of the water, and then evaporating the residue further at a temperature below the boiling point at the pressure used, the water vapour evolved being caused to diffuse in an indifferent gas immediately on leaving the liquid.  The freezing step is carried out by any known process.  The evaporation step is carried out with a large liquid surface and a relatively low pressure of the gas, which may be hydrogen, above the surface.  The diffusion path is kept short, preferably below 3 cm. and advantageously below 1 cm.  The indifferent gas may be streamed over the surface of the liquid, and the loss of the aroma vapours from the liquid may be completely suppressed by moving the gas towards the surface at a velocity at least equal to the diffusion velocity of the aroma vapours.  Skin formation in the evaporating liquid can be avoided by use of slowly rotating discs partly immersed in the liquid. The latent heat of evaporation may be supplied by means of pre-heated gas.  Concentrates containing over 65 per cent of solids and 80 per cent of the original vitamins can be made.ALSO:Aqueous liquids, such as natural juices, milk, extracts and the like are converted into liquid concentrates by first freezing out some of the water, and then evaporating the residue further at a temperature below the boiling point at the pressure used, the water vapour evolved being caused to diffuse in an indifferent gas immediately on leaving the liquid.

IPC: C09F5/06
Abstract: 283,233. Peczenik, C. E., and Schamberger, F. July 8, 1926. Patent abandoned on opposition. Fatty oils.-Varnish bases are prepared by heating the juice of the Anacardium, particularly the juice from the shells (cashew nut shell oil), in the presence of a hardening agent, for example a borate, to render it more viscous or solid. The catalyst may be added in finely divided form, the varnish-body formed being subsequently thinned with a solvent and the hardening agent separated as by filtration. An anticorrosive material such as a phosphoric or chromic acid salt or an alkaline salt may be added to the juice. The thickening action may be facilitated by the addition, as well as the hardening agent, of an oxidizing agent or by an aldehyde such as formaldehyde. Sodium peroxide or hydrogen peroxide may be used as hardening agents, with or without small quantities of sulphur or sulphur compounds, particularly in the case of the Anacardium Occidentale which is more difficult to treat than the Orientale variety. A small quantity of asphalt containing sulphur acts as a hardening agent when one per cent of formaldehyde is mixed with Anacardium juice. Dyes, pigments and drying oils may be added to the products, which may be dissolved in solvents such as alcohols, turpentine, benzene, benzol, or mixtures thereof, to form varnishes. In an example, 10 gallons of Ancardium Orientale nut shell juice are heated to 180-190‹. One pound of finely powdered borax is added in small quantities and the temperature is raised to 200-210‹ C. until a solid mass results. The mass is dissolved in a mixture of turpentine and benzole, the borax filtered off, and the solution applied to the articles to be coated. The coating may be stoved. Reference has been directed by the Comptroller to Specifications 259,959 and 272,510.
