Title: Linear polyether resin compositions
IPC: C08G18/64
Filed: 1962-04-10
Abstract: Coating, adhesive and moulding compositions comprise a substantially linear polyether condensation product, prepared by the process of the parent Specification, and having a weight average molecular weight of at least 50,000, together with a polyfunctional modifying agent capable of reacting with the oliphatic hydroxyl groups in the linear polyether condensation product.  Suitable reactive modifiers are aminoplasts, phenoplasts, polyisocyanates, organic or inorganic acid anhydrides, e.g. phosphorus pentamide or trimellitic anhydride, diepoxides, together with conventional catalysts.  Non-reactive modifying agents, e.g. solvents, polyalkylene glycols; or conventional plasticizers such as dillalphthalate, dioctyl sebacate, dibutylphthalate, butylbenzylphthalate, polyvinyl formals, polyesters, chlorinated biphenyls, hydrogenated rosins, rosin esters, triaryl or trialkyl phosphates; dyes; pigments; fillers, and ultra-violet screening agents may be included in the compositions. In the examples, the resin used was prepared by reacting equivalents of p,p1-bisphenol A and its diglycidyl ether in methyl ethyl ketone with caustic soda as catalyst.  The resin is used as a solution in a mixture of solvents, using as modifiers: (Examples 2-7) a urea-formaldehyde polyether resin; (Examples 8-10) a commercial methylol phenol polyether resin known as "Methylon"; (Example 12) melamine-formaldehyde resin; (Examples 13, 14) urea-formaldehyde resin; (Example 15) trimellitic anhydride; (Example 16) phosphorus pentoxide; (Example 17) a mixture of 2,4- and 2,6-toluene diisocyanate.  Specification 730,760 also is referred to.ALSO:Coating compositions containing linear polyether resins as claimed in the parent Specification and cross-linking agents therefor may be applied to a variety of bases or substrates, e.g. steel, brass, aluminium, tin plate, wood, glass, ceramics and synthetic resins, e.g. epoxy, acrylic, and vinyl resins, e.g. as bases for coatings of other resins or as primers for paints.  The compositions are particularly suitable for can coatings.  The coatings may be applied by the "fluidized bed" technique to an article heated above the melting point of the resin, or the powdered resin may be sprayed on to a preheated substrate, or applied by flame technique or by electrostatic deposition.  An article may be dipped into a batch of molten resin composition. Alternatively solutions or emulsions of the compositions may be applied by any conventional method; or the resins may be applied as plastisols or organosols.  The coatings may then be air dried and baked.  Specification 730,670 also is referred to.

Patent GB-477086-A (GB)
Title: Improvements relating to the refining of hydrocarbon oils
IPC: C10G21/12
Filed: 1936-05-21
Abstract: In the treatment of oils with solvents to remove undesired components, the solvents used consist of inorganic, aromatic or liquid aliphatic fluorine compounds.  Asphalt, wax, unsaturated and aromatic constituents are removed.  Aliphatic and aromatic fluorine compounds have selective solvent properties which increases with the number of fluorine atoms present.  Examples are, monofluorobutane, difluorpentane, monofluorhexane, o-fluoranisole, o-fluor phenetole, m-amido-trifluortoluene, p-fluoraniline, 2 : 4-difluoronitrobenzene, trifluorcresol.  The introduction of fluorine atoms in hydrocarbons containing other halogens renders the compounds selective when the number of fluorine atoms equals or exceeds the atoms of other halogens. Examples, trichlortrifluorethane, trifluordibromchlorethane tetra-fluordibromethane.  Non-selective fluorine compounds are used for dewaxing, for removing asphalt, and as diluents for sulphuric acid in refining treatment.  Examples, trichlormonofluormethane, pentachlormonofluorethane, defluordibromdichlorethane, fluorbenzene, fluortoluenes. Inorganic fluorine compounds which are selective are nitrogen trifluoride, arsenic or antimony pentrafluoride, tungsten hexafluoride, sulfuryl fluoride sulphur hexafluoride, fluorine compounds of tin, tellurium, silicon, and addition products of meta boric acid with hydrofluoric acid (HBO2.2HF).  The compounds having selective action may be used in admixture with (a) non-selective diluents miscible with oil, e.g. non-selective fluorine compounds, (b) selective compounds miscible with the selective fluorine compound, e.g. alcohol or in some cases, water, (c) selective solvents immiscible with the fluorine compound, e.g. phenol, furfurol or nitromethane, (d) diluents miscible with oil but only partially miscible with the selective fluorine compound, e.g. propane.  The non-selective fluorine compounds may be used as diluents for selective solvents such as phenol, furfurol, sulphur dioxide, aniline, or nitro methane.  For example, trichlormonofluor methane may be used with chlor-phenol, benzyl alcohol or quinoline in which it is soluble, or with aniline or furfurol with which it is partially miscible. Non-selective fluorine compounds used as dewaxing solvents may be diluted with benzene, toluene, methyl chloride, carbon disulphide, ethers or esters.  Oils containing wax and asphalt are first treated at elevated temperature with a fluorine compound, and after removing the precipitated asphalt, the solution is cooled to remove the wax.  The oil is then treated with a selective fluorine compound to form a raffinate and extract which are separated and freed from solvent.  The raffinate may be finally treated with a bleaching earth.  Lubricating-oils, residual oils, or benzine may be treated.  Specification 413,307 is referred to.

Filed: 1970-03-26
Abstract: 1,273,312. Coating apparatus work holders. SOC. GENERALE DE FONDERIE. 26 March, 1970 [26 March, 1969], No. 14726/70. Heading B2L. [Also in Division C1] An articulated table for hot enamelling of a bath 1 and similar castings comprises a cradle 3 pivotable about an axis X the cradle carrying a drive shaft 13, the drive shaft having a platform 14 thereon which rotates a bearer 8 for the bath about an axis Z, the platform having mounted thereon means for displacing the bearer 8 along the axis U independently of the angular position of the drive shaft 13. The cradle is moved about the axis X by means of a motor Ml, motors MT, MR and their ancillary equipment acting as a counterweight for the bath and its support The movement of the bearer 8 along the line U is provided by a double crank arrangement driven by the motor MT through a differential gear 45 shaft 25 which is coaxial with shaft 13 and a gear 26. Gear 26 drives gear 27 which is rigid with arm B1 and rotates on shaft 15. This causes the arm B1 of the double crank B1, B2 to move and gear wheel 32 rotatably mounted on shaft 33 of arm B1 walks around gear wheel 31 fixed to fixed shaft 15. Rotation of gear wheel 32 causes rotation of gear wheel 34 and hence arm B2. This produces movement of the bearer 8 along the line U and arms Cl and C2 are driven from the movement of bearer 8 and act only to maintain a straight line motion. Arms B3 and C3 support a counterweight which prevents eccentric weight about the axis 7. The weight 51 may be interchangeable. Motor MR provides drive for rotation of the platform 14 and hence the bath and counterweight about the axis 7. If the motor MT is stationary then shafts 13 and 25 rotate together due to the differential 45 and hence pure rotational movement is produced about the axis Z. In a modification (Fig. 8) the axis X passes through the journals 4 and through the centre of gravity of the bath. Quadrant gear 63 on the cradle is driven by a quadrant gear 64 driven from a motor M1 through a gearwheel 72 and a rod 68 pivoted at 71 and 69.
