Title: Improvements in and relating to the production of lacquers
IPC: C09D101/18
Filed: 1928-07-20
Abstract: 294,261. Tr³mpler, G. July 21, 1927, [Convention date]. Lacquers.-Cellulosic lacquers are formed by dissolving a mixture of soluble cellulose esters, such as acetyl or nitrocellulose, and natural or artificial resins to form a saturated solution in water-miscible solvents of fairly high boiling point (125-200‹ C.), such as diacetone alcohol, and adding water-miscible non-solvents or poor solvents boiling below 100‹ C. such as alcohol, in amounts such that the lacquers are substantially saturated in respect of the cellulose ester component. The lacquers may be applied in superposed layers without one layer having a solvent effect on the previous layer. Softening agents such as diethyl phthalate, fillers, colouring matters, small amounts of non-water-miscible solvents or non-solvents, such as toluene, or butyl acetate, &c. may be added. The lacquers may be made sprayable by the addition of hydrocarbons such as xylene, preferably selected to have a vapour pressure below that of the solvent and above that of the non-solvent or poor solvent. The Specification as open to inspection under Sect. 91 (3) (a) describes also lacquers not containing resins and containing other soluble cellulose compounds such as cellulose ethers. This subject-matter does not appear in the Specification as accepted.

Patent GB-240803-A (GB)
Title: An improved manufacture of petrolatum and petrolatum oils
IPC: C10G73/36
Filed: 1925-08-25
Abstract: Highly purified petrolatum and petrolatum oils are obtained by heating the crude products with fuming sulphuric acid until the impurities are converted into undissolved solid or semi-solid carbonaceous matter, and dissolving the purified petrolatum &c. from the mass.  In an example, 1000 kilograms of crude hydrocarbon grease are heated to 120-180 DEG  C. for 24-48 hrs. with 1500 kilograms of 20 per cent oleum, and then extracted with naphtha or benzol.  The solution is treated with alkali to remove acidity, and is distilled to remove the solvent.  The carbonaceous matter is pulverized and calcined at a dull red heat to produce a decolorizing carbon.  Any sulphur dioxide evolved is absorbed in alkali to produce sulphite. According to the Specification as open to inspection under Sect. 91 (3) (a), petroleum residues and heavy oils are purified by treatment with strong sulphuric acid at an elevated temperature. Preferably the material is first treated below 100 DEG  C., and then at over 200 DEG C., e.g. 160-170 DEG  C., sulphur trioxide is added to the acid, a hydrocarbon that is liquid at the temperature employed and unacted upon by the acid is mixed with the crude material, and the product is neutralized by treatment with calcium carbonate and filtration through porous clay.  Oil that has been treated once with acid as above may be freed from sulphonated compound by extraction with alcohols, light naphtha, or other solvent of the pure oil, or by further treatment with 20 per cent oleum.  In an example black cylinder oil is mixed with an equal weight of petroleum jelly that has already been treated with acid, and agitated with 1.5 parts by weight of 20 per cent oleum at 120-160 DEG  C. for 24 hours.  The liquid is drawn off, neutralized by agitation at 120 DEG  C. for 3-4 hours with 10 per cent of porous clay and 1.5 per cent of calcium carbonate, and filtered hot through porous clay.  The carbonaceous residue in the acid-treatment vessel is broken up and treated with naphtha, benzol, tetrachlorethylene, or other solvent of the purified oil. The solution is withdrawn, the solvent distilled off, and the oil neutralized and filtered.  Alternatively the solution is chilled and the precipitated oil or jelly allowed to settle out.  The carbonaceous residue is afterwards heated to about 400 DEG  C. to Q remove volatile impurities, ground in a ball mill, and maintained red hot in contact with air until about half is consumed.  A highly adsorbent carbon results.  Sulphur dioxide evolved during the operations is absorbed in a 28 per cent solution of sodium carbonate. The porous clay is revivified in known manner after treatment at about 50 DEG  C. with naptha or other solvent of the oil. This subject-matter does not appear in the Specification as accepted.

Abstract: 743,809. Lighting burners. ARMSTRONG SIDDELEY MOTORS, Ltd. July 15, 1954 [Aug. 1, 1953], No. 21408/53. Class 75(3). [Also in Group XII] In a gas turbine engine in which the combustion equipment is of the kind having a flame tube disposed within an outer air casing, a flame-producing ignition means comprises an igniter chamber having an outlet communicating with the interior of the flame tube. The igniter chamber has a fuel supply, an igniter and an air supply which is independent of the ambient air and is at such a pressure in relation to the ambient pressure that the outlet of the igniter chamber is "choking" i.e. the pressure ratio across the outlet is such that sonic velocity will be produced in the outlet. In Fig. 1 an annular flame tube 26 is mounted within an air space 23, the flame tube having J-shaped pipes 12 through which a mixture of fuel and primary air is supplied. The igniter chamber 17 is of streamlined cross-section and is disposed in the air space 23, its discharge orifice 25 opening into the flame tube. Fuel is supplied through the pipe 19 and air through the pipe 20 to the nozzle 21 and into the igniter chamber, the air being supplied from a high pressure air bottle through a reducing valve. The mixture of fuel and air is ignited in the chamber by means of an igniter 18. In a second embodiment, a baffle plate is disposed opposite the outlet 25 of the igniter chamber, the baffle having passages therethrough for flow of additional fuel which cools the baffle plate before issuing into the combustion zone within the flame tube. In a further embodiment, the igniter chamber is disposed outside the combustion apparatus and communicates with the flame tube through a duct formed as a diffuser. In Fig. 5, the ignition chamber 17a is disposed on the air casing 37, the discharge orifice of the chamber being at 25a. Opposite the discharge orifice is a venturishaped passage 40 leading into the flame tube, the flame issuing at sonic speed from the outlet 25a inducing air at the inlet 44 of the venturi passage and fuel from the line 42. The air and fuel will become mixed and ignited whereby the igniter flame will be increased and its velocity reduced.

Filed: 1961-06-14
Abstract: 985,668. Separating isotopes. W. DOBNER. June 14, 1961, No. 21425/61. Heading B1L. A method and apparatus for the separation of gaseous isotopes from a mixture thereof comprises intermittently directing volumes of the mixture at high speed into a longitudinally confined channel, between an inlet and an outlet, evacuating the speeding light isotopes of each volume of the mixture from the channel via the outlet, interrupting communication between the channel and the outlet and thereafter evacuating the remaining heavy isotopes from the channel. As shown, a gaseous isotope mixture is supplied to inlet port 13 at up to 10 Atmo absolute and a volume thereof passes 1000-10,000 times/min. into channel 12 formed in the peripheral zone of a rotatable cylinder 5 having end walls 8 and 9 in airtight sliding contact with walls 10 and 11 of a housing 1 when the inlet port is adjacent the channel which is in airtight sliding contact with a wall 16 of housing 1. The faster isotope molecules escape through the outlet orifice 14 maintained at a pressure down to 0À0001 Atmo absolute before rotation of the cylinder closes off the heavier residue which subsequently passes laterially into volume 4 maintained at low pressure by a vacuum pump. In a modification the inlet and outlet are not in axial alignment, thereby a separate injection of gas mixture takes place and subsequent rotation bringing the outlet end into alignment for withdrawal of the faster isotopes prior to subsequent lateral evacuation of the heavier isotopes. The rotating cylinder may be provided with a plurality of channels.
