Title: A process for making yarn for use in the manufacture of textile fabrics
IPC: D02G3/34
Filed: 1949-02-03
Abstract: 671,373. Spinning mixed fibre yarns. BURGESS, R. Feb. 3, 1949, No. 2950/49. Class 120(iii) Yarn containing intermingled fibres of a plurality of different colours is formed on the cotton system from staple cotton, rayon or synthetic fibres by forming a plurality of rovings from, such staple fibres, dyeing at least one roving a colour different from that of at least one other roving, doubling and drawing the different coloured rovings to form a roving in which the fibres of different colour are intermingled, thereafter repeatedly by doubling this roving with another similarly doubled and drawn roving of similar colour characteristics to increase the thoroughness of the intermingling, and spinning the resulting roving to form a yarn. Rovings dyed two or more different colours may be used, or one or more dyed rovings may be used with one or more undyed rovings. For example, a roving of colour a may be drawn and doubled with a roving of colour b to produce a roving colour a + b which is then doubled and drawn with another roving of colour a + b; or the roving of colour a + b may be doubled and drawn with a similarly produced roving of colour c + d to produce a roving of colour a + b + c + d which is then doubled and drawn with a similar roving of colour a + b + c + d. The initial intermingling of the fibres may be affected at one of the usual intermediate frames. Alternatively, an extra doubling and drawing operation may be utilized; for example, colour 1.6-hank rovings from the usual slubbers are doubled and drawn as an extra operation to produce a 1.6-hank mixed-colour roving, such a roving being then passed to usual intermediate frames, where it is doubled and drawn repeatedly, and thence to a spinning frame.

Patent GB-407812-A (GB)
Title: Improved process for the manufacture of heavy lubricating oils and products producedthereby
IPC: C10M101/02
Filed: 1933-01-31
Abstract: Lubricating-oils are prepared by de-waxing a mixture of a non-centrifugeable unpressable wax-containing distillate and a petroleum residuum which renders the wax distillate centrifugeable, the proportions of residuum used lying between R=85 - 5.6\stV - 50 and R=65 - 5.6\stV - 50, in which R is the percentage by volume of residuum in the mixture, and V is the viscosity of the distillate in seconds S.U.V.  An unpressable non-centrifugeable wax distillate is obtained from an asphalt base crude oil containing a high proportion of wax by distilling with steam to remove light oils and a pressable wax distillate. The desired unpressable wax distillate is then distilled off, and the residue is heated in vacuo in the same or a second still to obtain a further unpressable wax fraction which is preferably returned to the first distillation stage.  A suitable residuum is obtained from a crude paraffin base oil low in asphalt content by distilling with steam to remove light oils and a pressable distillate, and an unpressable wax distillate which is combined with that obtained from the asphalt base-oil.  The residuum thus obtained has a viscosity of 100 secs. S.U.V. at 210 DEG  F. and is mixed with about twice its volume of the wax-containing distillate which has a viscosity above 50 secs. S.U.V. at 210 DEG  F.  The mixture is diluted with heavy kerosene and treated with sulphuric acid preferably in two steps.  The acid sludge is separated from the oils assisted if necessary by warming and blowing in air.  The oil is then neutralized by addition of caustic soda or of fullers earth and is digested at 550 DEG  F.; finally steam is admitted to distil off the kerosene.  The fullers earth is then filtered off and the oil is then de-waxed by adding naphtha, chilling slowly to -25 to -45 DEG  F. and removing the precipitated wax by a centrifuge. The de-waxed oils are then passed to a fractionating still in which naphtha is removed together with a neutral lubricating oil distillate leaving a residuum.  The residuum is filtered through fullers earth or clay yielding the final lubricating oil.  In the case of Texas oils and similar oils of high wax content, the mixture of wax distillate and residuum may be diluted with naphtha and submitted to a de-waxing treatment to remove the greater portion of wax before the main purification treatment with acid &c.  The chilling stage in this preliminary de-waxing operation is preferably effected at about -10 DEG  F.  After centrifugal separation of wax the oil is freed from naphtha, mixed with kerosene and a further amount of residuum and submitted to treatment with acid, clay &c. as in the main process. The wax obtained in the second de-waxing stage usually contains oil and is preferably diluted with kerosene and recycled with the oil undergoing centrifugal treatment.

The 'bar 36 is connected to the lower end of a rocker arm 34 pivoted at 35 (Fig. 4). The bent over upper end 34' of the arm 34 is connected by a spring 38 to the lower end of a knee-shaped operating lever 26. In the position shown in Figs. 4 and 6 (latter not shown) the lower end rests on a stop 33 and the bar 36 bears against the discharge tube 36. On depression of the lever 26 the at 29 the rocker arm pivots in an anticlockwise direction and causes the upper end 34' thereof to move along curved slot 37 until it reaches the left-hand position of Fig. 7 (not shown). In this position the bar 36 bears on the supply tube 15 [Fig. 8 (not shown)] and water is discharged onto the sheet P 1 . The lever 26 is returned to its original position by spring 30 upon release of the lever. The rocker arm 34 is, however, prevented from immediate return by engagement of the bent end 34' with the right-hand end of recess 46 in pivot bar 41 held against end 34' by spring 43 [see Fig. 9 (not shown)]. Once the lever 26 returns to its original position the lever raises the arm 41 to allow sudden release of the rocker arm back to the position where the bar 36 bears on the discharge tube 18 again. The heating cylinder 7 has a vortex plate 70 [see Fig. 10 (not shown)] and the height of the discharge tube 18 is adjustable.
