Title: Purifying and desulfurizing zinc sulfide ores and concentrates
IPC: C22B1/10
Filed: 1952-12-11
Abstract: Zinc sulphide ore containing volatilizable compounds of metallic impurities such as lead, tin and cadmium is treated with an oxidizing gas insufficient in amount for complete oxidation of the sulphur content while maintaining a temperature sufficient to volatilize the said compounds, and the ore is then transferred to a second zone where it is completely oxidized by blowing through it an oxidizing gas to maintain the bed in a fluidized state.  At least the second stage is effected autogenously.  As shown, the first stage may be effected in a multiple hearth <PICT:0718769/III/1> furnace 10 and the oxidizing gas may be exit gas from the fluidized bed reactor 11 of the second stage, supplied to the furnace by duct 16 after removal of dust in cyclone 15.  The gas may be sufficient to oxidize less than half the sulphur, and the temperature may be above 850 DEG C.  The partially oxidized ore is transferred by conduits 25, 29 to the fluidized bed reactor 11 to which air is admitted at 32 to complete the oxidation.  The exit gases from both stages containing 14-16 per cent. sulphur dioxide pass through waste heat boilers 18, 37 and electrical precipitator 20, 39.  In an alternative embodiment the first stage is also conducted in a fluidized bed reactor.

Title: Improvements in the pattern mechanism of a circular knitting machine
IPC: D04B15/68
Filed: 1959-09-16
Abstract: 936,344. Knitting-machines. SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTVI. Sept. 16, 1959 [Sept. 16, 1958], No. 31520/59. Class 74 (2). Patterning mechanism is provided in a circular machine to produce overall tuck stitch effect in the fabric produced and comprises a series of continuously rotating cam rings 5 concentric with the needle cylinder 1 and arranged in two groups 5a, 5b to operate on jack butts for needle selection at the first and third stations of a four feeder machine. The cam rings of each group have associated with them a corresponding number of levers 12, 14 which are supported on shafts carrying at their upper ends levers 13, 15. These levers 13, 15 engage selectors 10, 11 at each feeding station which normally are urged inwardly towards the needle cylinder to engage the jack butts. A ring 20 also concentric with the needle cylinder supports cam followers 16, 17 interposed between the cam rings 5 and levers 12, 14 and also a wedge shape member 26 for engagement with the levers 12 at the first feed. The ring 20 is rotatably adjustable under control of the pattern drum of the machine and in the position shown in Fig. 5 the levers 12, 14 are free from movement of the followers 16, 17 and accordingly the selectors 10, 12 engage all of the butts on the jacks to ensure that the needles clear. If the ring 20 is moved to the position shown in Fig. 7 where the followers 16, 17 engage the levers 12, 14 then overall tucking is effected by the cam rings causing selection of the selectors and influencing the needle jacks. When the ring 20 assumes the position shown in Fig. 7 then the levers 14 are uninfluenced and the selectors occupy their innermost position to cause all of the needles to clear at the third feeding station whereas the member 26 causes the levers 12 to withdraw all of the selectors 10 at the first feeding station to cause them to actuate only the long butt jacks which cause a 1 x selection at that feeding station. The needle jacks have long and short butts at the various levels corresponding to the selectors as well as butts being omitted at some levels on some of the jacks to enable the desired tuckwork pattern to be achieved.

Patent GB-971594-A (GB)
Title: Process for the production of zirconium compounds,more especially basic zirconium sulphate
IPC: C01G25/06
Filed: 1961-09-04
Abstract: Zirconium compounds are prepared by adding an acid, e.g hydrochloric or nitric acid to a suspension of an alkali metal zirconium silicate, said acid being added initially in an amount equivalent to the alkali metal portion of the silicate and at such a rate that the temperature does not rise above 100 DEG  C. and then further acid is quickly added in an amount necessary to completely form a zirconium salt of the acid and the precipitated silica is separated out. When hydrochloric acid is employed, zirconium oxychloride is formed. Basic zirconium sulphate may be precipitated from the liquor obtained after the removal of the silica by the addition of sulphate ions. Coarse-grained basic sulphate is obtained by slowing heating the sulphate containing solution at 40-50 DEG  C. until it becomes cloudy and then heating more strongly whereas rapid heating of the solution to 95-100 DEG  C. results in the precipitation of a fine-grained basic sulphate. The basic sulphate may be washed and calcined to yield zirconium oxide.  Specification 924,811 is referred to.
