Patent GB-700711-A (GB)
Title: Synthetic drying oils and methods for preparing same
IPC: C09F5/00
Filed: 1951-06-01
Abstract: A synthetic drying oil is prepared by condensing a substantially saturated linear organic polymer having a number of carboxyl groups along its chain with an unsaturated hydrocarbon containing an active methylene group.  The hydrocarbon preferably contains conjugated double bonds and suitable compounds are cyclopentadiene, pentadiene-1,4, 2-methylcyclopentadiene, indene and their homologues. The carboxyl-containing polymer may be prepared by copolymerising an alkyl or aryl substituted ethylene having 3 to 10 carbon atoms, e.g. propylene, isobutylene, butene-1, the amylenes, decenes, styrene, ring-substituted mono- or di-methyl styrenes or ethyl- or chloro-styrenes, with a mono-olefinic aldehyde or ketone, e.g. acrolein, methyl vinyl ketone and isopropenyl methyl ketone. Homopolymers of a vinyl ketone and copolymers of carbon monoxide and ethylene may also be used.  It is preferred, however, to acylate saturated copolymers of a polymerisable cyclic compound such as styrene, paramethyl styrene or indene, with an aliphatic olefin of 3 to 10 carbon atoms, e.g. isobutylene, 2-methyl butene-1 and iso-octene, or with acrylonitrile.  The acylating agent may be acetyl chloride or propionyl, stearyl, benzoyl, oleyl, linoleyl, di-linoleyl, sebacyl and phthalyl chlorides.  The resulting carboxyl containing polymer preferably has a molecular weight of between 1,000 and 20,000. The condensation with the hydrocarbon is effected by dissolving the polymer in an inert solvent such as toluene or naphtha, adding between 0.5 to 1.2 mols of the hydrocarbon per carboxyl group present and one mol. of a metal alcoholate condensing agent per mol. of hydrocarbon, and maintaining the mixture at 10 DEG to 15 DEG C. for 2 to 24 hours.  Suitable metal alcoholates are C2 to C10 alcoholates of sodium, potassium, calcium and magnesium.  After reaction, a slight excess of acetic acid is added and the mixture filtered through powdered silica to give a clear reddish solution. Reduced to 45 per cent. polymer and treated with lead and manganese driers, a drying oil or varnish is obtained which forms tack-free flexible films resistant to water, grease, soap and caustic material and to ultra-violet light. These may be improved by baking for one hour at 250 DEG F.  The drying oils may be diluted with solvents such as naphtha and mineral spirits, blended with other oils such as linseed and tung oils, with ester gum, alkyd and other resins and bodied with modified phenolics and they may be compounded with pigments &c.  They may also be used in the form of aqueous dispersions.

Class 60 Apparatus for grinding. polishing or similarly treating a cylindrical or approximately cylindrical workpiece, such as a boiler tube 3, comprises a series of rotary tools 24 such as grinding wheels, wire brushes, buffing or polishing pads &c., carried by tubular members 19 pivotally mounted by fulcrum pins 20 on an extension of a shaft 10 rotatably mounted in bearings 11, 12 supported by plates 9, 9 mounted on a table 5. A separate pneumatic motor is provided within each member 19 for rotating tool 24, the air supply to the motor passing through the hollow shaft 10 into tubular member 19. The shaft 10 is rotated through gearing 13, 14 by a pneumatic motor 18. The tools 24 may be rotated about their axes in the same or opposite sense to their rotation about the axis of the workpiece. Springs 21, 22 are connected to the members 19, spring 22 being adjusted by a screw adjustor 22a to vary the pressure with which the tools 24 engage the work piece 3. A plate 23 mounted as an extension of the shaft 10 comprises a disc having radial slots one slot engaging with each of the members 19 to prevent relative circumferential displacement of the members. A manually operable cam plate 25 adjustably mounted on the extension of the shaft 10 has cam portions normally out of engagement with the members 19; partial rotation of the plate 25 by the operator causes radial outward movement of the members 19 to lift the tools 24 out of engagement with the work piece. The table 5 is reciprocated longitudinally of the bed plate 1 by -a screwed shaft 6 rotated through gearing 8a, 8b by a pneumatic reversible motor 8. A trigger 26 on the table engages a lever 27 when the table has completed its longitudinal movement. Movement of the lever 27 is transmitted by levers 28, 29 to a pivotally mounted member 30 provided with two abutments 31, 31 one or other of which moves an arm 32 to reverse the air supply to the motor 8; the arm 32 is provided with an adjustable weight 33 to ensure its positive movement. Compressed air is supplied from reservoir 34 through lines &c, 18a to motors 8, 18 and through air line 18b and hollow shaft 10 to the pneumatic motors in the tubular members 19. The motors 8, 18 may be replaced by a single motor; alternatively electric motors may be employed.
