Alternatively they may be stainless steel wires and have a coating of brass outside the above limits. The outer layer 12 may be an oil and ozone resistant synthetic polymeric material or a natural rubber and preferably contains 0À1% of sulphur. As shown, the reinforcement layer 11 is of braided high tensile steel wire which contains copper coated wires to the ratio of 7: 2 or 5: 1 to brass coated wires. In a modification, Fig. 2 (not shown), the hose comprises a synthetic rubber inner tube (20) surrounded in turn by a high tensile steel wire (21), a synthetic rubber layer (22), a second layer (23) of braided high tensile steel wire having copper coated to brass coated wires in the ratio of 6: 2 and a cover (24) which contains sulphur and adheres only to the brass coated wires.

Alumina is produced from an aluminous ore by : -(1) crushing, optionally calcining, then digesting the ore with boiling aqueous H 2 SO 4  ; (2) extracting from the insoluble residue of (1) the sulphates of iron, potassium and magnesium by washing with water, and concentrating and crystallizing them; (3) diluting the solution of sulphates resulting from (1) thereby reducing its free H 2 SO 4  content to below 650 g./litre and cooling this solution to less than 50‹ C., then, by saturation with HCl gas, precipitating hydrated aluminium chloride, which is separated by filtration; (4) cooling the filtrate while keeping it saturated with hydrochloric acid in order to precipitate NaCl, and filtering; (5) heating the filtrate thereby liberating HCl gas and aqueous HCl; (6) concentrating the filtrate to adjust its H 2 SO 4  content to from 750 to 850 g./litre and re-using the solution for treating a new ore batch; (7) purifying the hydrated aluminium chloride by one or more crystallizations in an aqueous HCl solution; (8) calcining the chloride at a temperature of at least 500‹ C. producing alumina and hydrochloric acid. The aqueous washing solution from (2) may be evaporated to a b. pt. of 122‹ C./760 mm. and allowed to crystallize and the crystalline mixture washed with H 2 SO 4  and calcined to dissociate the sulphates of Fe, Mg and Al. The resultant SO 2 /SO 3  mixture may then be converted to H 2 SO 4  and reintroduced into the system for re-use. The calcination product is extracted with hot water to dissolve K 2 SO 4  and leave a mixture of oxides of Fe, Mg, Al, and Ti which may be used directly in ferrous metallurgy. The gaseous hydrogen chloride liberated in stages (5) and (8) may be reused in pptn. cycles (3) and (4) while the aqueous acid also liberated may be recycled for further use in recrystallization stage (7).

Abstract: 1,250,236. Fractional distillation; stripping towers. TREADWELL CORP. 18 March, 1969 [26 March, 1968], No. 14157/69. Heading B1B. [Also in Division F4] Components of differing volatilities are separated from a liquid mixture by contracting a stream of the liquid mixture with a countercurrent stream of vapour in a distillation column in which at least one zone, comprising several adjacent stages, is maintained at substantially uniform temperature, the vapour leaving each stage being compressed before it is introduced into the next stage. Fig. 2 shows a distillation column divided into superposed stages containing contacting devices (e.g. plates or packing). The liquid mixture flows downwards from stage to stage by gravity. Fans 21 are provided for drawing vapour from each stage and introducing into the next higher stage. Liquid mixture to be separated is introduced at an intermediate level of the column. The overhead vapour, taken off through conduit 15, is passed through a coil in the reboiler 16 attached to the base of the column. Part of the condensed distillate is returned to the head of the column through conduit 14, and the remainder is withdrawn from the system as the more volatile product. The less volatile product is withdrawn from the bottom of the column. In an example relating to the separation of a mixture of propane and propylene, the pressure at the top of the column is 1349 mm. Hg., and the pressure at the bottom is 842 mm. Hg., while the corresponding temperatures are -30F. and -40F. respectively. The distillate is propylene, and the bottoms product is propane. The process may also be carried out in a horizontal vessel (Fig. 3, not shown) provided with internal fans attached to a common axial shaft, the liquid being transferred from stage to stage by external pumps. Fig. 4 shows a stripping tower suitable for separating concentrated SO 2  from dilute aqueous solutions. The tower has sections 28, 37, 40.. packed with polypropylene rings. The dilute solution is introduced into the top section of the tower; and steam is introduced at the base through inlet 27. The. vapours are transferred upwards from stage to stage by hydraulically-driven centrifugal compressors 35, 39, 41.. SO 2  gas (87%) leaves the top of the tower, and stripped liquor flows out at the base.

When the web roll is complete, the screws 7 are loosened and the flanges 5 are simultaneously tapped lightly against the opposite edges of the convolutions of the web so that the convolutions are jogged into perfect alignment. When the web is aligned the flanges 5 are positioned against the opposite edges thereof and locked to the shaft to confine the realigned roll, which may then be used again in the processing operation. The flange 5 and the collar 6 may be separate pieces (Figs. 3 to 5, not shown). The projections 8 may be in the form of pins, as shown, or may comprise continuous rings.

In a process for the preparation of a protein concentrate for human or animal consumption, animal tissue such as whole fish is comminuted and the resultant suspension is subjected to an evaporation-extraction step wherein the suspension is contacted in counter current relation with vapours of a volatile solvent to remove a major part of the water from the suspension, the water-enriched solvent from this step being subjected to rectificationdistillation, the resulting water-freed solvent being recycled to the evaporation-extraction step. In the extraction step part of the fat and odour is also removed from the suspension. The residual fat and odour content may be further reduced by an additional exttraction step using fresh solvent. Suitable solvents are acetone, ethanol or isopropanol. The process may be carried out in the apparatus shown in the Figure wherein animal tissue is comminuted in the grinder 2 and fed to mixer 4 wherein the liquid content of the comminuted tissue may be increased by the addition of for instance, volatile solvent. The suspension is then passed to the contacting apparatus 11, wherein it is contacted with solvent vapours entering the apparatus through conduit 14. The treated suspension leaving the bottom of apparatus 11 is passed to a separator 19, and the tissue fraction may then be passed to apparatus 32 for further extraction. The water enriched solvent from the top of apparatus 11 and the fat containing solvent from separator 19 are passed to distillation column 17 for purification and recycling. Part of the recycled solvent may be passed to the apparatus 32. Fat enriched solvent from the separator may be passed to the mixer 4. A mixture of fat and water is drained from the bottom of column 17 and separated in the decanting device 35. The energy for the rectifying distillation is provided by a circulation evaporator 38 wherein part of the liquid from column 17 is evaporated by steam passing through the evaporator via conduits 41 and 42.
