Patent GB-694359-A (GB)
Title: Lubricating oil composition
IPC: C09F1/00
Filed: 1949-09-22
Abstract: Tall oil esters used as lubricant additives are prepared by esterifying tall oil with one or more alcohols or glycols or mixtures of alcohols and glycols.  The esters are "complete" esters, i.e. they contain no free hydroxy groups.  Dihydric alcohols containing sulphur, such as diethanol sulphide may be used.  Particularly useful alcohols are those having eight carbon atoms, e.g. C8oxo-alcohols, 2-ethylhexanol and n-decyl alcohol.  The esters are prepared by conventional methods, e.g. by using sulphuric acid as a catalyst and a solvent such as naphtha, benzene or toluene.  Various tall oil esters are described, e.g. the methyl, butyl, isopropyl, 2-ethyl hexyl, O8oxo-alcohols, n-decyl, hexadecyl and "Oanol" (Registered Trade Mark) esters. Specification 560,286, [Group III], is referred to.ALSO:A lubricant composition comprises a lubricating oil base and a complete ester of one or more alcohols or glycols or mixtures of alcohols and glycols with tall oil.  The lubricating oil base may be any conventional lubricating oil, mineral or synthetic.  A "complete" ester is one containning no free hydroxy groups.  A dihydric alcohol containing sulphur, e.g. diethanol sulphide, may be used.  An equimolecular mixture of oleic acid and abietic acid may be used instead of tall oil.  Preferably alkyl alcohols containing from 1 to 24 carbon atoms may be used, especially those containing from 8 to 10 carbon atoms, e.g. C8 oxo-alcohols, 2-ethyl hexanol and n-decyl alcohol.  Examples are given of compositions obtained by blending various esters in a phenol extracted coastal crude stock. Specification 560,286 is referred to.

Title: Improvements in and relating to the control of electric motor drives for rolling mills and the like
IPC: H02P5/46
Filed: 1951-10-19
Abstract: 709,297. Control of two D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 19, 1951 [Oct. 19, 1950], No. 24455/51. Class 38(3) [Also in Group XXXV] Motors 3 and 4 each drive one of a pair of rolls forming part of a reversible rolling mill and are respectively supplied from Ward- Leonard generators 1, 2, having amplidyne exciters 8, 9. The motor circuits have a common conductor 5-6 comprising an element 7 which is both inductive and resistive, the points 5 and 6 being at equal potential when the motor currents are the same. In the event of unbalance of the motor currents a voltage is developed across the element 7 which causes such energization of field windings 47 48, of the exciters 8 and 9 that the excitation of the heavily loaded generator is reduced and that of the lightly loaded generator is increased, so equalizing the torques of the two motors. The inductance of the element 7 provides a quick reaction to any unbalance of motor current. The provision of rectifiers 50 allows passage of the no-load currents of the motors through the element 7 without appreciable energization of the windings 47, 48. The amplidyne 8 has a control winding 13 which is energized from a constant source 12 through rheostat 15 and reverser 16, an opposing exciter field winding 17 being energized in accordance with the voltage of the generator 1. Further exciter windings 18, 19, 20, restrict the rate of change of excitation of the generator 1 and so prevent current surges in the armature circuit of the motor 3, as described in Specification 698,064. The amplidyne 9 is similarly controlled. The motor field windings 37, 38, are supplied from the source 12 through an adjustable resistor 51 and a step-down amplidyne 39 which is controlled in the manner described in Specification 698,064. When the source comprises a single generator, a connection between the point of interconnection of the motors and a point of potential intermediate those of the generator output terminals includes an impedance across which a signal voltage representing the difference of the motor currents is generated. This signal voltage is used to control the outputs of a pair of exciters connected to control the field excitations of the pair of motors.

Heading BIB [Also in Division C2] A mixture of glycerol with 1,2,3- and 1,2,4- butanetriols is submitted to steam distillation under reduced pressure and at a temperature not exceeding 200C, in order to obtain three separate fractions rich in glycerol, 1,2,3- BT and 1,2,4-BT, respectively. The mixture obtained by hydrogenolysis of sorbitol or mannitol is freed from ionic impurities by contacting it with ionic exchange resin, and the mixture is then dehydrated by distillation in a packed fractionating column. The dehydrated mixture is submitted to steam distillation under reduced pressure (50 mm.) in a second packed column, in order to remove glycols. The mixture is next steam-distilled at a temperature below 200C in a third column in order to separate unreacted hexitol as bottoms fraction, from as distillate comprising glycerol and the two specified butanetriols. This distillate is then submitted to steam distillation at a temperature not exceeding 200C in a fourth column in order to distil over a mixture of glycerol and 1,2,3-BT, leaving a residue comprising 1,2,4-BT admixed with glycerol. The distillate from the fourth column is steam-distilled in a fifth column to distil over the 1,2,3-BT traction; and the liquid withdrawn from the base of the fifth column is steamdistilled in a sixth column in order to obtain purified glycerol as distillate. The distillation-refsidue is advantageously recycled to the hexitol-removal column, the bottoms fraction of which is recycled to the hydrogenolysis system. In an alternative embodiment, the ,1,2,3-BT is removed from the glycerol before the 1,2,4-BT.
