Abstract: <PICT:0744461/IV(c)/1> <PICT:0744461/IV(c)/2> The process and apparatus of the parent Specification, as applied to the dyeing of cloth, webs, strips, warps or the like, wherein the cloth is passed first through a bath of dyeing or dye-developing liquor and then through a bath of molten metal, the dyeing liquor or dye-developing liquor, e.g. sodium hydrosulphite, floating as a layer on the surface of the molten metal, is modified in that (a) the liquor is fed to the layer at substantially the same rate as it is absorbed by the cloth and is heated just prior to its entry to the layer, the heating being applied to the liquor once only without recirculation of the liquor back to the heater; (b) the level of the layer actuates a modulating valve for controlling the flow of liquor to the layer; and (c) the layer is maintained of uniform composition by circulating the liquor out of and into the layer through a circuit positioned on the discharge side of the heater.  As shown, Fig. 1, dyeing liquor from one of the reservoir tanks 1 is withdrawn through a filter 3 and fed by a pump 2 through a heater 10 to the dyebath 15, which comprises a layer of the liquor floating on the surface of a molten metal bath 16.  The cloth to be dyed is passed through the dyebath, then through the molten metal bath and out through a Glauber salt bath 46, which also floats on the molten metal surface.  The flow of liquor to the dyebath is controlled by a modulating valve 25 which is actuated through a float valve 28 by a change in level of the dyebath liquor. The heater 10 may be electrically, gas, oil or steam heated and, in the case of steam, the supply is controlled by a valve 19 which is actuated by a controller 20 responsive to a thermostat 24.  Liquor is fed to dyebath 15 (Fig. 2) through a main conduit 14, a pair of branch conduits 30, 31 and a further pair of branch conduits 32, 33 which discharge into opposite sides of and into the ends of the dyebath, the liquor being distributed through gallery pipes 34 having slots designed to discharge the liquor in a direction parallel to the cloth.  To ensure constant composition, the liquor is withdrawn from the ends of and returned to the middle of the dyebath by a pump 36, baffles being provided to deflect the incoming liquor in a direction parallel to the cloth.  Specification 681,983 also is referred to.

Patent GB-887794-A (GB)
Title: Hydrogenation of hydrocarbons
IPC: C10G45/16
Filed: 1958-04-21
Abstract: A process for refining an asphalt-containing liquid hydrocarbon comprises mixing the hydrocarbon with an additive chosen from light and middle oil distillates and with a finely divided absorbent so as to at least partially absorb the asphalt on the absorbent, adding a hydrogen containing gas in the form of finely divided bubbles to produce a dispersion, heating the resultant mixture under a pressure in excess of atmospheric pressure at a temperature at which the hydrocarbon is decomposable and then separating the product from the gas and absorbent.  Preferably the process is effected under a pressure of 30-70 atmospheres at a temperature of 420-460 DEG  C. The starting material may be mineral oil, crude oil, coal tar products or shale oil and may contain from 35% by weight of material insoluble in heptane.  The preferred absorbent is powdered coke, but activated charcoal, inorganic oxides such as silicon dioxide and aluminium oxide may also be used.  The absorbent may be activated with iron sulphate or iron oxide.  Foaming is assisted by the addition of chemical foam producers or small quantities of water. The additive may be paraffinic such as n-heptane, a kerosene distillate or a gas oil or aromatic such as toluene.  A small quantity of sulphur assists the process.  Mixing may be effected by means of a nozzle described in Group II.

IPC: D06B3/10
Filed: 1955-05-02
Abstract: <PICT:0789996/IV (b)/1> <PICT:0789996/IV (b)/2> Washing or dyeing &c. apparatus for the continuous treatment of fabric webs or strands, comprises a liquor tank 10 divided by partitions 12, 14, 16, 18 and 19, baffles 23, 25, 27, and 29, upper and lower rollers 51, 52, 58, 60 and so on over which the strand passes, pressure rollers 74, 75, the upper roller 75 of which may be adjusted by means of pneumatic piston cylinder units, and a take-off roller 94.  The partitions are provided with slotted openings 102, 103, 106, 108, 110 arranged at different heights and on different sides of the tank, Fig. 4, so that liquor pumped or gravity fed into the tank 10 through an opening 100 levels in the respective compartments at 103, 105, 107, 109 and 53, Fig. 1, and moves in counter flow in criss-cross fashion through the length of the tank, leaving via an outlet 112.  The strand or fabric is fed into the machine through an eye 32, around a tensioning arm 36, under a vertically guided dancer roll 48 and over a roller 51. The strand then passes down and around the roller 52 and up again to the roller 51 and continues to pass between the rollers until their lengths are transversed.  The strand then passes to the other compartments and traverses the pairs of rollers in like fashion, and is then taken between the pressure rollers 74, 75 and trained around the rollers 74, 90 as in the manner already described, finally emerging from between the pressure rollers at 92 and passing to the take-off roller 94. The strand may however cross in passing between pairs of rollers, Fig. 7 (not shown), thus increasing the degree of flexing of the strands, and strand guide fingers 150, 152 are employed.  The rollers are driven one from another by a motor M and Vee-belts, and each of the pulleys 122, 120, 118, 116 may be selectively adjusted for pitch diameter by hand wheels 155 whilst the machine is running, so that the speeds of the rollers may be individually adjusted to vary the stretch of the strand.  Automatic speed control of the machine motor M may be obtained by movement of a rheostat 140, Fig. 1 (see Group XXXV).  In a modification multiple liquid treatments may be carried out if additional inlet and outlet connections are provided in the tank and the various interior chambers arranged to contain different liquids &c., the apertures 102, 104 being unnecessary in this case.
