Patent GB-560115-A (GB)
Title: Improvements in or relating to cellulose ether compositions
IPC: C08B15/00
Filed: 1942-08-25
Abstract: A composition capable of being made relatively water-insoluble by heating, comprises a water-soluble cellulose ether and a water-soluble methylated polymethylol melamine and an acidic catalyst.  The composition may be used for obtaining protective or ornamental coatings on paper, textiles, or other materials.  Paper may be rendered water-, grease-, and oil-proof, and made specially suitable for wrapping food-stuffs.  The composition may be formed into transparent sheets or films, and the sheets may be used in making safety glass.  The composition may be moulded.  Paper sheets may be coated with the composition, assembled in a pile, and consolidated by heat and pressure to give a laminated structure.  In an example, a water-soluble methylated hexamethylol melamine is dissolved in an aqueous solution of methyl cellulose and a small amount of tartaric acid is added. The composition is tested by dipping weighed strips of glass cloth in the solution, removing them and baking at 250 DEG  F., applying second and third coats of composition in the same manner, weighing, immersing in distilled water for measured periods of time, drying and weighing after each immersion.  Methylated hexamethylol melamine may be obtained by reacting methanol and hexamethylol melamine at a temperature below 30 DEG  C., under conditions more acid than pH 4, the acidity being regulated by an acid which can be removed as an insoluble salt to give a solution free from electrolytes, concentrating the solution at a temperature not greater than 50 DEG  C. and precipitating the crystalline ether from the concentrated solution.  Water-soluble ethyl or other ethers of cellulose may be used instead of methyl cellulose.  Instead of tartaric acid, the catalyst may be phosphoric acid or other acid or acid-yielding salt, ester, or other compound. The Specification as open to inspection under Sect. 91 comprises also water-soluble cellulose ether compositions containing water-soluble alkyl ethers of dimethylol urea, and acidic catalysts.  Dimethyl and diethyl ethers of dimethylol urea may be obtained in a similar manner to that described above for methylated hexamethylol melamine.  This subject-matter does not appear in the Specification as accepted.

Title: A process for manufacturing highly viscous products obtained by the polymerisation of fatty oils
IPC: C10M101/04
Filed: 1937-04-29
Abstract: Acids may be removed from products prepared by polymerizing non- or semi-drying fatty oils in the presence of boron trifluoride by washing with aliphatic alcohols and/or ketones containing less than 5 carbon atoms, viz. methyl, ethyl, n- and iso-propyl, nsec.-, tert.-, and iso-butyl alcohols, acetone, and methyl ethyl ketone.  In the case of alcohols the washing is carried out at a temperature not above 60 DEG  C.  The polymerizate may be dissolved, e.g. in chloroform, carbon tetrachloride, gasoline, or benzene, before treatment with the above solvents and may be previously or simultaneously freed from boron trifluoride with treatment with an aqueous liquid, e.g. water, 50 per cent ethyl alcohol, or 50 per cent acetone.  Acids and boron fluoride may be removed simultaneously by using solvents containing not more than 10 per cent of water, e.g. 96 per cent alcohol or 98 per cent acetone.  Mineral oil may be added to the acid free polymerizates during or after working up.  In examples: a mixture of rapeseed and soya bean oils is polymerized in presence of boron trifluoride, the polymerizate is dissolved in benzene and twice washed with water acetone mixture, then once with 98 per cent and twice with 97,5 per cent acetone; (2) a similar polymerizate to that of example 1 is washed four times with 94,7 per cent ethyl alcohol; (3) sunflower oil was polymerized in the presence of boron trifluoride, the polymerizate dissolved in benzene, washed twice with 90 per cent and twice with 100 per cent methyl alcohol. Specifications 428,993, 463,932, and 478,928 are referred to.

Title: Improvement in oil testing apparatus for motor vehicles
IPC: G01N11/06
Filed: 1927-05-09
Abstract: 276,281. Mason, F. B. May 9, 1927. Testing lubricating efficiency of liquids.-Apparatus for comparison of oils comprises a container for a standard liquid, a container for the liquid to be tested each communicating with a corresponding receptacle for the liquids and means whereby the liquids are caused to flow under like conditions from the receptacles to the containers and vice versa for the purpose of observing the rates of flow. Containers 14, 23 provided with gauge glasses 10, 11 are fitted with floats 15, ending in valves 17, finding seatings in the necks of the vessels which communicate by pipes 30, 34 with aT-piece 31 m which is a three-way valve. The lower ends of the containers are connected by pipes 38, 43 with a receptacle 39 separate from but integral with the crank case, and with the crank case respectively. In the lower ends of each container is located a neck in which is bored a standard hole. By-pass pipes 45, 47 connect the pipes 38, 43 with the tops of the containers. Normally, the valve 35 is turned so that pipes 30, 34 are open to the atmosphere. In use, the valve 35 is turned to close the pipes 30, 34 to the atmosphere and open them to the pipe 32 and hence to the vacuum spaces of the engine cylinder. Oil from the crank case rises in the container 23, and from the standard oil receptacle 39 on the container 14 until the floats rise and the valves 16 close. The three-way valve is now turned to open the pipes 30, 34 to the atmosphere and the liquids are allowed to run back into the receptacle. The comparative rates of flow as observed in the gauge glasses afford an indication as to whether the oil in the crank case should be changed. The receptacle 39 is positioned in the crank case to observe similar temperature conditions for both liquids. A vent will be necessary for the chamber 39 and in some cases for the crank case.
