Title: Improvements in the manufacture of staple fibre yarns from continuous filaments
IPC: D01G1/08
Filed: 1932-11-10
Abstract: 411,506. Producing staple fibre yarn from continuous filaments. DREYFUS, H., 22, Hanover Square, London. Nov. 10, 1932, Nos. 31768/32 and 7011/33.<7> [Class 120 (iii).] A staple fibre yarn is produced from continuous filaments by subjecting them to a breaking load which breaks the filaments and brings them into a permanently extended condition, and then conditioning the staple fibre material by treating with a shrinking and/or softening agent to restore at least in part the extensibility lost during the breaking operation. The conditioning agent may be liquid or steam, and the conditioning treatment is preferably performed whilst the yarn is in package form ; such packages may consist of completely spun yarn, or an intermediate product such as sliver or roving. The package support is designed so as to yield under the shrinking action of the yarn, and consists e.g. of sheet metal twisted into the form of a cone or cylinder. The package support may be held on a former during winding, removed therefrom and placed on a smaller former for the conditioning treatment. Shrinkage may also be allowed for by winding the yarn slackly, or by winding the yarn on relatively obtuse angled cones. Instead of steam, shrinkage and/or softening may be effected by means of aqueous liquids e.g. heated soap solution, or even water ; other liquid agents are acetic, formic and lactic acids, diacetone alcohol, acetone, ethers including the cyclic ethers, homologues and substitution products thereof, esters and etheresters of olefine and polyolefine glycols, phenols, mono-di- and tri-acetins, ethyl lactate, methylene chloride, chloroform, tetrachlorethane and like latent solvents for celulose derivatives either alone or with diluents such as water, benzene, toluene or the like ; benzine, petrol ether or the like ; carbon tetrachloride, trichlorethylene, and like halogenated compounds which are comparatively inert towards cellulose derivatives. The conditioning agent may be applied in liquid form or as a vapour. In an example, a yarn of staple lengths of cellulose acetate filaments produced by breaking continuous filaments is wound in cone form f ¢ lb. weight, on a plain or perforated springy twisted metal support, and the packages immersed in live steam for 6 hrs. In a further example, similar packages are treated with a solution of 50 per cent by volume of methylene chloride in benzene at 15‹C., centrifuged, washed, partly dried by further centrifuging, and dried by stoving. Specifications 403,738 and 403,739 are referred to. The second Provisional Specification refers to Specification 410,805.

Title: Improvements in or relating to the treatment of complex ores containing zinc
IPC: C22B15/00
Filed: 1923-12-28
Abstract: Ores &c. containing zinc, roasted if necessary, are treated with dilute hydrochloric acid which may be of 12 DEG  B<\>ae and at 80 DEG C., the treatment being such that the solution first obtained is brought into contact with more ore for the re-precipitation of materials such as calcium and lead which it is not desired to dissolve.  Carbonic acid may be employed in this further treatment of the solution with the ore in order to remove the calcium and lead from the solution.  The solution is treated with magnesium sulphate to precipitate any remaining lead, and with metallic zinc to remove copper.  The zinc is then precipitated as oxide or carbonate by magnesia or by magnesium carbonate in presence of carbonic acid.  The solution of magnesium chloride remaining is treated with magnesia to produce oxychloride which is then calcined to regenerate magnesia and hydrochloric acid in known manner.  The residue of the ore, to which may be added the precipitates obtained in the purification of the zinc chloride solution, may be smelted or cyanided by known methods for recovering the contained metals.

Abstract: 509,571. Indicating liquid levels. TIMPSON, A. F. C. Nov. 10, 1938, No. 32686. [Class 123 (i)] [Also in Group XIX] In a liquid-level indicator, a base-plate 1 is secured over an aperture in the top of a container, and a rotatable pin 2 carrying a spiral spindle 3 projects downwards, the lower end being weighted at 5. The upper end of the pin 2 carries a circular dial 6 marked in inches, surrounded by a concentric ring 10 marked in feet. A glass cover 12 is provided, and an outer cover 21 carries a removable cap 24 through which the reading may be observed. The underside of the ring 10 is provided with a ring of recesses 15 corresponding to the foot divisions, and an index arrow is marked on the clamping ring 13. The dial 6 carries a spring 17 with a pin 17a engaging the recesses 15, and a similar spring 18 with pin 18a is fixed to the base-plate on the opposite side. The pin 17a is normally out of engagement with a recess 15 and the pin 18a normally in engagement. The dial 6 is rotated by the rising liquid, and at the end of a revolution a fixed projection 19 causes the pin 17a to engage a recess 15, and simultaneously a projection 20a on the dial 6 frees the pin 18a from engagement with a recess 15. The ring 10 is thus locked to dial 6 until the next " foot " division on the dial 10 is reached. The spring 18 is then freed from the projection 20a and the next recess 15 is engaged to lock the ring 10. Simultaneously, the spring 17 is freed, and the rotation of dial 6 continues alone. The spindle 3 may be screw-threaded, or may be a twisted strip passing through a float 26 guided by projections 27 to prevent its rotation.
