Title: Improvements in or relating to acrylate ester polymers
IPC: C10M145/14
Filed: 1946-10-02
Abstract: Compounds which may be used as pourpoint depressants and viscosity index improvers in lubricating oils are prepared by copolymerizing a mixture of alkyl acrylates, the alkyl groups containing 10 to 18 C atoms and the average in the mixture being from 11.0 to 13.5 C atoms. Commercial mixtures of alcohols may be used to prepare the mixed acrylates, one such mixture containing lauryl, decyl, octadecyl, cetyl and tetradecyl alcohols.  A mixture of decyl and lauryl acrylates may also be used. Specification 491,800, [Group IV], is referred to.ALSO:A mixture of two different alkyl acrylates containing from 10 to 18 carbon atoms in the alkyl groups are copolymerized, the acrylates being so selected that the alkyl groups in the mixture have an average number of carbon atoms of 11.0 to 13.5. Commercial mixtures of alcohols may be used to prepare the mixed acrylates, one such mixture containing lauryl, decyl, octadecyl, cetyl and tetradecyl alcohols.  A mixture of decyl and lauryl acrylates is also specified.  Bulk or solution methods are specified, the solvents named being toluene, heptane, refined petroleum naphtha, refined kerosene, gas oil, lubricating oil, methanol, isopropanol and ethyl ether.  Benzoyl or acetyl peroxides or tertiary butyl hydroperoxide may be used as catalysts.  A range of 50-100 DEG  C. is given as the reaction temperatures, while the absence of oxygen is preferred.  The copolymers are useful as pour point depressants alone or with others such as methacrylate polymers, and viscosity index improvers for lubricating oils, for improving waxes, asphalt, greases, resins, gums and rubbers and in making hydraulic oil compositions.  Specification 491,800 is referred to.

Title: Improvements in or relating to the manufacture of textile materials
IPC: D06M17/02
Filed: 1935-10-24
Abstract: 464,792. Compound fabrics. BROWN, R. R. H., COOPER, J. M., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 24, 1935, No. 29433. [Class 140] In the manufacture of doubled and multiple fabrics, comparatively strong solutions in dilute aqueous caustic alkali of cellulose esters and ethers, other than cellulose xanthate, of the kind which are insoluble in water, are used as the adhesive for cementing the layers of fabric together. Examples of suitable cellulose derivatives are glycol cellulose, methyl cellulose, ethyl cellulose, cellulose sulphate and cellulose phosphate. A solution of more than 5 parts per 100 is regarded as comparatively strong. The layers of fabric are coated with the solution, and caused to adhere under pressure. The assembled fabric is then subjected to a raised temperature and /or to the action of a coagulating agent e.g. an acid, to precipitate the cellulose derivative, and is finally washed and dried. In an example, two pieces of bleached calico are spread on one side with a 7 per cent. solution of glycol cellulose in 7À5 per cent. sodium hydroxide solution. The pieces are dried, a second coating of solution applied, and the pieces are doubled in a doubling machine. After being dried at a raised temperature the material is introduced into a bath of 3 per cent. sulphuric acid, after which it is washed and dried. Specifications 410,152, 410,153, 416,590, and 420,529 [all in Group IV], are referred to.

Title: Improvements in or relating to devices for peeling citrus fruits
IPC: A47J17/04
Filed: 1951-12-17
Abstract: 708,149. Orange &c. peelers. LEVITIN, J. March 13, 1953 [Dec. 17, 1951; May 30. 1952], Nos. 29472/51 and 13761/52. Class 28(2) A peeler for citrus fruit comprises a body 173 provided with at least one depending self-adjusting peel cutter 181 resiliently mounted, e.g. on a leaf spring 182 and having a blunt lower edge to press on the inner skin without cutting through it. Instead of a spring a piston &c. may be used. In operation a handle 174 is held between the fingers and pushed round the fruit whereby spaced cutters 177 make shallow cuts in the skin followed by the yielding cutters 181 which deepen the cuts into the pith, and followed by other pith cutters 183 which complete the cuts. The device may then be pulled back so that a tooth slits the skin to allow a peelraising front 186 to be inserted and traversed round the fruit between the spaced cuts to lift the cut strip away from the fruit. Bevelled edges 178 and 184 and blunt undersides are provided on the respective pith cutters 177 and 183. In Fig. 2 a handle 190 carries upward facing cutters comprising skin cutters 193 interrupted by limited-depth yielding pithcutting blades 197 and followed by complete pith-cutting blades 199. Surfaces 195 limit the penetration of the first skin cutters 193. The blades 197 are each mounted on a leaf spring 198. A tooth in the handle makes a slit so that the peellifting nose 202 can be entered under the strip of skin and traversed around the fruit. In a simpler form, Fig. 17, the fruit is rotated against a concave surface on a handle 1 whereby a single cut is made by the sharp edge 3 of a skin cutter 2 followed by pith cutting by the sharp edge of a cutter 8 mounted on the end of a flat spring 7. The blunt and rounded base of 8 bears on the inner skin and prevents penetration thereof. The peel can be lifted by a nose 9. One .end of such devices 207, Fig. 6 (not shown).may be used to prise apart the fruit segments. Other forms of the device are described and shown one of which, Figs. 8 and 9 (not shown), makes three spaced cuts marking two adjacent strips to be. peeled off. Specification 675,670 is referred to.

Title: Improvements in or relating to methods of producing novolaks
IPC: C08G8/06
Filed: 1951-12-19
Abstract: A phenol-furfural novolak is made by condensing in presence of a catalyst which is an alkaline-earth metal hydroxide, (1) a phenol, e.g. phenol itself or an alkyl derivative; (2) furfural, and (3) ammonia, or a primary alkylamine or arylamine, or a compound yielding them under the reaction conditions, e.g. an ammonium salt, or a reaction product of furfural with them.

The novolaks may be mixed with fillers, colouring substances &c., and with hexamethylene-tetramine or parformaldehyde to form moulding powders. Novolaks made from a low furfural/phenol molar ratio may be further condensed with another aldehyde, e.g. formaldehyde.  In examples, (1) phenol, furfural, ammonia and water are refluxed, then calcium hydroxide or magnesia are added and the temperature raised from 102 DEG -158 DEG  C. over two hours while distilling off water.  The calcium hydroxide may be added before the initial refluxing, (2) phenol, furfural, ethylamine or aniline, and water are refluxed, calcium hydroxide added and the temperature raised slowly to 160 DEG C. whilst distilling off water.

Abstract: 1437090 Combustion gases with reduced soot content SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 25 June 1973 [26 June 1972] 29768/72 Heading C5E - Combustion gases having substantially reduced soot content, e.g., less than 0À3% by wt., are produced by partially combusting carbonaceous fuels and passing the soot-containing gases at substantially the temperature and pressure of the partial combustion into a non- catalytic soot-conversion zone in which soot particles are held, e.g. for at least 5 seconds, and converted into carbon monoxide by reaction with steam and/or carbon dioxide present in the gas, and withdrawing gas of reduced soot content from the zone. The soot-conversion zone consists of at least one bed of ceramic material which may consist of (i) layers of packed perforated bricks the perforations of the bricks in a lower layer interconnecting with the perforations of an upper layer to form elongated tubes in the direction of gas flow, the tubes having a diameter of 0À5 to 2À5 cm. and presenting a surface area available for gas contact of 30 to 200 sq. metres per cubic metre of bricks, through which the gas flows at an average gas velocity of 1 to 10 metres per second; or (ii) a fluid bed of ceramic particles, of average diameter 10 to 1000 microns, through which the gas flows at a superficial velocity of 0À1 to 1 meter per second. The temperature in the sootconversion zone may be from 1300‹ to 1500‹ C. and the pressure from 10 to 300 atmospheres. The gases leaving the conversion zone are passed through a heat exchanger. Apparatus for producing the substantially soot-reduced combustion gases comprises a brick lined partial combustion reactor free of internals and solids with one or more inlets for fuel, oxygen-containing gas and steam and an exit for partially combusted gases, and a sootconversion vessel containing at least one bed of ceramic material connected to the partial combustion reactor with an exit for substantially soot-reduced gases which may be connected to a waste heat boiler.
