Patent GB-951674-A (GB)
Title: A method of, and apparatus for controlling foam in fermenters
IPC: B01D19/04
Filed: 1961-05-26
Abstract: A method of controlling foam in fermenters comprises the steps of passing a mixture of foam and entraining gases through a separator which separates the mash (liquid) content of the foam from residual gases, obtaining a measurement which is a function of the rate at which mash is separated out by the separator and admitting anti-foaming agent to the fermenter in amount dependent upon the measurement.  In one embodiment, Fig. 1, foam and entrained gases from a fermenter or yeast propagator a are separated in a cyclone b and the difference between the liquid levels D h of the mash in the return pipe b2 and the fermenter a is used as a measure of the foam content in the fermenter; the pressure difference is transmitted through <PICT:0951674/C3/1> <PICT:0951674/C3/2> compressed air lines c, d, to a differential pressure regulator e, the diaphragm e3 of which transmits its movement through linkage e4 and f as a varying continuous control of the needle valve g for dispensing the anti-foaming agent. A throttle valve b3 enables the difference D h in level to be adjusted for a predetermined rate of return of the mash through pipe b2.  The differential pressure regulator e may be replaced by a piston valve, Fig. 2, in which the pressure differential transmitted by pipes c and d, to chambers e1, e2, causes movement of a piston member i, i1 against a return spring p; as the piston descends, communication between the parts k1, k2, is established by way of the continually increasing transverse passage or bore i2 in the piston whereby anti-foaming agent is dispensed through the ports in the correct amount.  The piston has adjusting screw l1 for stressing the spring and stop l2 for the piston. In a further embodiment, Fig. 3 (not shown), the difference in vapour pressure between the atmosphere and the input side of the separator is utilized to actuate the diaphragm e3 of Fig. 1.

Title: Manufacture of colouring matters
IPC: B67D1/00
Filed: 1935-07-10
Abstract: Stable metal phthalocyanines are prepared by heating together a phthalic anhydride or a corresponding free acid, or a monoester thereof, or an ammonium salt thereof, or an amide or imide of the said acid, or an o-cyanobenzoic acid or an ammonium salt or an ester thereof, with urea or a heat-decomposition product thereof (other than ammonia) and a substance consisting of or containing a metal adapted to give a stable - metal phthalocyanine.  The term phthalic anhydride includes also the anhydrides of naphthalene-1 : 2- and 2 : 3-dicarboxylic acids; substituted acids mentioned are the halogen-, nitro- and carboxy derivatives of phthalic acids. An excess of urea or heat-decomposition product over the theoretical requirements is usually necessary since it behaves both as a reactant and as a flux. Pressure or the presence of additional reagents such as sulphaminic acid, imidodisulphonic acid or nitrile trisulphonic acid (cf. Specification 457,786), may be an advantage.  The general reaction temperature is 200--220 DEG  C. Reaction may take place in stages so that the heating of a metal yielding substance with a phthaluric acid or a phthalimimide is p  included in the invention.  In examples: (a) a mixture of phthalic anhydride, urea and aluminium chloride are heated together at 210 DEG  C.; instead of aluminium chloride, ferric chloride, ferrous chloride, chromium fluoride, chromium chloride, cobaltous chloride, cupric chloride or nickelous chloride may be used, and in the case of cupric chloride the yield may be improved by working in the presence of ammonium sulphamate; (b) 4-chlorophthalic anhydride, urea and cupric chloride are heated together at 210 DEG C.; (c) 3 : 6-dichlorphthalic anhydride, urea and cupric chloride or nickel chloride are heated together at 210 DEG  C.; (d) 4 : 5-dichlorphthalic anhydride, urea and cupric chloride are heated together at 210 DEG  C.; (e) phthalic anhydride, 3 : 6-dichlorphthalic anhydride, urea and cupric chloride are heated together at 220--240 DEG  C.; (f) o-cyanobenzoic acid, or the methyl ester thereof, or phthalic acid monoethyl ester is heated with urea and aluminium chloride or cupric chloride at 210--240 DEG  C.; (g) phthalic diamide urea and cupric chloride, or cuprous chloride or copper bronze are heated together at 160--220 DEG  C.; (h) phthalimide urea and cupric chloride are heated together at 160--220 DEG  C., the reaction optionally being carried out in an autoclave; (i) diammonium phthalate, urea (or the product obtained by heating urea to 200 DEG  C.) and cupric chloride are heated together at 160--220 DEG  C.  A sample has been furnished under Sect. 2 (5) of a product made by heating together trimellitic acid, urea and cupric chloride at 240--300 DEG  C.

Patent GB-742093-A (GB)
Title: Method of reducing the corrosion of waste heat boilers used for the cooling of roaster gases from the roasting of zinc sulphide ores and concentrates
IPC: C22B1/10
Filed: 1953-07-16
Abstract: In the roasting of zinc sulphide ores with cooling of the resulting sulphur dioxide-containing roaster gases in a waste heat boiler, the roaster gases are cooled after leaving the combustion chamber of the roaster and before entering the boiler to a temperature below 850 DEG C and preferably below 800 DEG C.  Cooling may be effected by the use of a gas flue of sufficient length and heast dissipating capacity, by external cooling, or by introducing cool gas into the roaster gas to be cooled.  The cool gas is preferably introduced into the roaster gases at or near the point at which they leave the roasting furnace, but may be introduced near the point at which they enter the boiler, provided adequate mixing means are employed.  The cool gas may be roaster gas withdrawn from a point after the waste heat boiler and recycled, cool roaster gas from another furnace, or air at any temperature up to 800 DEG C.  Other gases which may be used are sulphur dioxide, oxygen or nitrogen.  In the case of a flash roaster, cooling may be effected by introducing cool gas into the bottom of the roaster between the combustion chamber collecting hearth and the discharge hearth.  The boiler may have a maximum operating pressure of 250 lbs. per sq. in.

Abstract: 478,361. Rolling. SENDZIMIR, T. July 16, 1936, No. 19783. Convention date, July 16, 1935. [Class 83 (iv)] Strip is passed under tension through a rolling-mill 4 by feeding- means (rollers) 1 and 2 having no reducing function the linear speeds of which are fixed, proportional to the desired elongation, e.g. by the positioning of the belt 9 between the cone pulleys 5 and 6, so that if the rolls meet strip portions of different thickness or hardness the relative speed of feeding in and feeding out is unaffected thereby. The rolls 4 are also driven at a peripheral speed of constant ratio to the feeding-speeds, e.g. by other cone pulleys 7, 8 and an adjustable belt 10 thereon. An endless metal strip 3, Fig. 3, is reduced between the rolls 4, the speed of the driven feed and draw off drums 30 and 35 being adjusted to the linear elongation of the strip caused by the rolls 4 while a jockey drum 39 pulled by a tension cable 411 moves to take up the slack. The drums are provided with a chain of rings &c. 36 to press the. strip against the drum to increase the grip but without hindering the movement of the strip owing to the rings, e.g. 86, Fig. 12, being rotated by shafts 85, rotated by a gear ring 88 fixed on the drum. The chain of rings are pressed on the drum peripheries by fluid pressure cylinders 34, 38. The strip 3 may also be magnetically held to the drums by the effect of windings 96, Fig. 15, set in slots in the drum and magnetizing it thereby, or may be pressed by a band 91 which may also be magnetized. Fig. 5 shows another drive for the rolls 4 and feed rollers 1 and 2 with epicyclic change speed gears for the feed rollers with oil operated motor-generator devices 15, 16. The remaining apparatus is described in Specification 478,360. Specification 423,664 also is referred to.
