Abstract: 134,207. Norsk Hydro - Elektrisk Kvµlstofaktieselskab. Oct. 23, 1918, [Convention date]. Crystallizing.-In crystallizing liquids in a tube A rotating on a substantially horizontal axis, the upper part of the tube is maintained at an elevated temperature while the lower part of the tube is cooled. By this means, over-cooling of the liquid, which is particularly undesirable in fractional crystallization of salts, is prevented. The tube A is formed with longitudinal ribs B, and is supplied with heating and cooling fluid bv suitable devices C, D. The liquid under treatment enters at one end of the tube A and is discharged at the other. The Specification as open to inspection under Sect. 91 (3) (a) also states that the supply of heating-agent may be omitted provided that only the lower part of the cylinder is cooled. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to controlling devices for aeroplanes
IPC: B64C3/52
Filed: 1921-09-21
Abstract: 190,774. Fairey Aviation Co., Ltd., and Fairey, C. R. Sept. 21, 1921. Balancing.-To prevent burbling, the ailerons or trailing portions of the wings of an aeroplane are divided along their median plane into upper and lower sections; these sections normally lie in contact with one another, but, when an aileron or trailing portion is depressed, the lower section is moved through a greater angle than the upper section. The upper and lower sections of each aileron &c. may be pivoted about a common axis, about separate axes one in advance of the other, or about separate axes situated approximately at the upper and lower surfaces of the wing; or one section may be hinged to the other; or, as shown in Fig. 7, one section may be hinged to the lower ends of links connected to the pivot of the other section. A biplane is shown having its ailerons divided into upper and lower sections 32, 33, 52, 53, corresponding sections on the upper and lower planes being connected by cords 49, 50. The sections 32, 53 are pivoted at 34, 55 to the wings near their upper surfaces, the section 53 having arms 53<a> extending to the pivot 55. The other sections are pivoted to the lower ends 35, 54 of links 36, 56 suspended from the pivots 34, 55, the section 52 being carried by arms 52a. Lugs 37, 57 normally steady the lower ends of the links. The sections 32, 33 have, arms 38, 39, of unequal length, coupled together by a link 42 and connected to a control wire 43. The sections 52, 53 have arms 58, 59 coupled by a link 61 and connected to a cord 63 acted upon by a spring 66 which normally tends to raise the ailerons. The control wire 43 is connected to a control column similar to that shown in Figs. 2 and 3 of Specification 134,556. The effective length of the arm connected to the upper section is in each case greater than that of the arm connected to the lower section, so that the lower section has the greater angular movement when the ailerons are moved down from or up to their mean position. During upward movement from the mean position, the two sections of each aileron move together as a whole about their upper pivots 34, 55 without separation. Instead of being of equal chord length, the upper or lower section may have a longer chord. The ailerons &c. may be controlled by mechanism described in Specifications 132,541, 134,556 or 135,520, irrespective of whether the hinged flaps are simultaneously movable in the same or opposite directions at will or whether a balance wire is employed as described in Specification 135,522. The device may be used where the trailing portion of each wing is divided into separate parts independently and differentiallv controllable as described in Specification 135,521. one modification being described in which both the upper and lower pairs of the wings of a biplane are so divided and the movable parts controlled by the mechanism described in Specifications 135,520, 135,521 and 135,522.

Abstract: 482,425. Yarns. FINLAYSON, D., and LEVERS, J. F. Sept. 29, 1936, Nos. 25379/37 and 25380/37. Divided out of 482,376. Drawings to Specification. [Class 120 (iii)] A composite yarn, resembling a wool yarn, comprises one or more yarns of crinkled cellulose acetate having in the composite yarn at most only a low degree of twist, associated with one or more high twist yarns having in the composite yarn a degree of twist such that they will shrink on treatment with hot aqueous liquor and the proportion of crinkled yarn in the composite yarn being substantially greater than the proportion of high twist yarn. The yarns may be associated by a doubling twist and a length of high twist yarn may be doubled with a greater length of crinkled yarn. The denier of the crinkled yarn is preferably substantially greater than that of the high twist yarn and at most 30 per cent of the total denier of the composite yarn is constituted by the high twist yarn. The high twist yarn may be of high tensile strength. The crinkled yarn may be produced by subjecting cellulose acetate filaments of flat cross-section to the action of hot aqueous liquors and the spinning solution may contain a plasticizing agent as described in Specification 459,781. The crinkling may be produced by twisting yarn of cellulose acetate filaments, setting the twist and then removing at least part of the twist as described in Specifications 424,880, 442,073, and 464,981 or a yarn or bundle of flat filaments may be crinkled by subjection to one of these processes and, either before or after such treatment, subjected to the action of hot aqueous liquors. The high twist yarn may be crepe shrunk after the doubling operation by treatment with hot aqueous liquors. The crinkled filaments may be continuous or discontinuous and the high twist yarn may be of a natural or artificial material or it may be of normal cellulose acetate subjected to a process such as described in Specifications 448,816, 448,817, and 448,917, [all in Group IV]. The high twist yarn is preferably of high tenacity and may have been stretched or partially or completely saponified or the twist may be inserted while the yarn is under the influence of steam or hot water as described in Specifications 437,019, 438,589, 438,590, and 438,591. It is preferred to insert the doubling twist in the same direction as the original twist in the high twist yarn. Examples of composite yarns of components of various deniers and twists and of various doubling twists are given. Specifications 455,021, 474,401, and 474,402 also are referred to.

In a linking machine the print dial is rotatable on a carrier which is mounted for adjustment about an axis parallel to the dial axis-and offset therefrom in the direction of the stitch-forming mechanism. A point dial 10 is rotatable about a vertical axis 53 on a carrier 11 mounted on a hollow head 12 which is supported by a plate 13 and is pivoted thereto, for tilting, about a horizontal axis 14. A column 19, upstanding from carrier 11, extends in an arm 21 which supports swing mechanism 18 projecting outwardly of carrier 11. Plate 13 is supported at the upper end of an inclined hollow pedestal 17, and is rigid with a hollow shaft 50 journalled in said upper end, whereby plate 13 may be rotated for adjustment of carrier 11 about the axis of shaft 50. Said axis is offset from axis 53 in the direction of mechanism 18, and is posi-  tioned midway between the outermost part of mechanism 18 and the diametrically opposite part of carrier 11. Pedestal 17 is mounted on a hollow base 37 journalling a foot-operated turntable 38 which is positioned vertically beneath carrier 11 and is connected by a chain 41 to a shaft 43 at the bottom of pedestal 17. Shaft 43 is connected by a  shaft 45 and universal couplings 44, 46 to a shaft at the top of pedestal 17, the latter shaft being connected by a chain 48 to shaft 50. The arrangement is thereby such that the mechanism 18, when positioned adjacent the operator actuating the turntable 38, is no closer to the operator than is the carrier 11 when the mechanism 18-is in the diametrically opposite position. A motor 32, mounted in pedestal 32, is coupled via a shaft 35 to a shaft 15 journalled in shaft 50, shaft 15 being coupled to a shaft 29 actuating the mechanism 18. A circular skirt 51 depends from carrier 11 and is formed with a lower upturned portion 52.

Title: Improvements relating to the preparation of oximes by reduction of primary or secondary nitro compounds of aliphatic or cycloaliphatic hydrocarbons
Filed: 1953-09-15
Abstract: Cycloaliphatic oximes are obtained by passing a cycloaliphatic nitro-hydrocarbon in the vapour phase mixed with hydrogen over a metal and/or metal oxide hydrogenation catalyst at 90-300 DEG  C. The process may be carried out at elevated or reduced pressure but is preferably effected at atmospheric pressure.  Inert gases such as nitrogen or water vapour may be present in admixture with the hydrogen during the reduction process.  Specified hydrogeneration catalysts are metals of the 8th group of the periodic system, especially nickel, cobalt, and iron; platinum and copper catalysts; and compound catalysts consisting of oxides of more than one metal such as copper oxide-cadmium oxide, calcium oxide-silver oxide-zinc oxide or silver oxide-chromium oxide catalysts.  The preferred catalyst is zinc oxide which may be employed at high reduction temperatures, e.g. 185-260 DEG  C.  In examples: (1) a preheated mixture of hydrogen and nitro-cyclohexane is passed through a heated reaction column filled with a zinc oxide catalyst (obtained by heating zinc carbonate at 400 DEG  C. and then compressing into tablets) and the reduction carried out at 250 DEG  C. and at atmospheric pressure to yield cyclohexanone oxime together with a small amount of cyclohexyl amine; (2) as in (1) except that the reduction is carried out at 190 DEG  C.; (3) a gaseous mixture of nitrocyclohexane vapour, hydrogen, and nitrogen, prepared by evaporating nitrocyclohexane at 103-105 DEG  C. while passing a mixture of nitrogen and hydrogen through it, is passed through a catalyst chamber containing a catalyst consisting of a complex compound of the oxides of chromium, zinc, silver, and calcium prepared by adding an aqueous solution of zinc nitrate, silver nitrate, and calcium nitrate to a warm ammonium bicromate solution and heating (see Group III), the reduction being carried out at 103-105 DEG  C at atmospheric pressure to yield cyclohexanone oxime and a small amount of cyclohexyl amine.  Other nitro compounds specified are methyl nitro cyclohexane, and nitro-cycloheptane.ALSO:A hydrogenation catalyst used in the vapour phase reduction of cycloaliphatic nitro hydrocarbons to oxines by means of hydrogen (see Group IV(b)) comprises a complex compound of the oxides of chromium, zinc, silver, and calcium. in the atomic ratio Cr:Zn:Ag:Ca=50:40:5:5 which is prepared by adding an aqueous solution of zinc nitrate, silver nitrate, and calcium nitrate to a warm ammonium bichromate solution, heating the resulting precipitate to about 400 DEG C., and then compressing into tablets. Other hydrogenation catalysts specified include mixtures of oxides, e.g. copper oxide-cadmium oxide, calcium oxide-silver oxide-zinc oxide, and silver oxide-chromium oxide.
