Abstract: 415,278. Controlling the balloon during the twisting and winding of yarn, filaments, &c. by cap spinning-apparatus. BRITISH CELANESE, Ltd., 22, Hanover Square, London. Oct. 19, 1933, No. 29017. Convention date, Oct. 19, 1932. [Class 120 (ii).] The length of material in the balloon during the twisting and winding of filaments, yarns, threads and the like by cap spinning-apparatus, particularly in the twisting and winding of artificial filaments continuously with their production, is controlled so that it is greater when the diameter of the bobbin or package is small than when it is large. As shown, the invention is applied to the twisting of artificial threads during production. The guides 24 are carried by a rod 22 which is operated by a strap 26, ratchet gearing 36 and reduction gearing 34, 35 from the pump shaft 32, so that during the filling of the bobbin the guides are lowered from the position shown in dotted lines to that shown in full lines, whereby the balloon is so controlled that contact with the separators 13 and the top of the cap is prevented. The Specification as open to inspection under Sect. 91 comprises also the application of the invention to twisting during delivery, the yarn guide being moved upwardly away from the bobbin as the yarn is wound off. This subjectmatter does not appear in the Specification as accepted.

Title: An improved spray drying process and apparatus for evaporating solutions, emulsions,suspensions and the like
IPC: B01D1/18
Filed: 1950-11-30
Abstract: In a spray-evaporating process, the drying gas is sent through the drying chamber with so great an axial velocity of flow (V metres per sec.) that the expression <FORM:0712746/III/1> is at least equal to 5, where ti is the inlet temperature and tu is the outlet temperature of the drying gas (in  DEG C.) and G is the quantity of water (kgs. per sec.).  The velocity is greater than that previously employed, enabling the dimensions of the drying chamber to be reduced and effecting economies in heat.  In an example ti is 160 DEG  C., tu is 80 DEG  C. and V is 0.67 metres/sec. evaporated per unit of time. The diameter of the chamber is 2.5 metres and its <PICT:0712746/III/1> height 3 metres whereby a particle is in the chamber for 4.5 secs. As described milk is introduced into a drying chamber 1 through an atomiser 4 driven by a motor in a housing 5. Drying gas is supplied through a chamber 7 communicating with the drying chamber 1 through an annular opening 8 provided with adjustable guide blades 9 adapted to be turned about vertical axes whereby the gas may be directed more or less inwardly towards the central portion of the drying chamber 1.

Patent GB-656112-A (GB)
Title: Manufacture of tertiary alcohols
IPC: C07C29/132
Filed: 1948-11-16
Abstract: Tertiary alcohols are produced by a process comprising reacting at elevated temperatures a hydroperoxide compound in which the hydroperoxide group is linked to a tertiary carbon atom with an amine compound of general formula <FORM:0656112/IV (b)/1> wherein R and R1 are alkyl, cycloalkyl, substituted alkyl, aryl or aralkyl or the methylene groups adjacent to the nitrogen atom of cyclic nitrogen compounds such as piperidine and piperazine and R1 may in addition be hydrogen and R2 stands for hydrogen or an alkyl, cycloalkyl, substituted alkyl, aryl, aralkyl or acyl group.  Suitable amines include mono-, di- and tri-methyl, ethyl, propyl, isopropyl and butylamines, aniline, mono- and di-methyl and ethylaniline, mono- and di-ethyltoluidine, mono-, di- and triethanolamine, dimethyl formamide, diethyl formamide, piperidine, piperazine, hexamine and ethylene diamine.  Suitable hydroperoxides include the hydroperoxides of isopropyl benzene, methylcyclopentane, a - and b -isopropyl naphthalene and tertiary butyl and the mono- and di-hydroperoxides of diisopropylbenzene.  The amine compound, the hydroperoxide compound or the hydrocarbon from which the hydroperoxide has been derived may serve as solvent.  The reaction rate increases when the proportion of amine compound to hydroperoxide compound is increased.  The reaction is exothermic and it is advantageous to provide means for controlling the reaction temperature.  The carbinols and unchanged amine compound may be recovered by fractionation or the latter by extraction with aqueous acid.  Ketones and unsaturated compounds are also produced when prolonged heating has been necessary.  Phenyl dimethyl carbinol is produced by heating isopropyl benzene hydroperoxide with, in examples (1), (2) and (3), triethylamine, isopropyl benzene being present as solvent in the latter; (4) dimethylaniline; (5) diethylamine; (6) n-butylamine; (7) hexamine; (8) triethanolamine; (9) diethanolamine; (10) dimethylformamide; (11) piperidine; (12) piperazine with isopropylbenzene as solvent. In examples: (13) diisopropyl benzene monohydroperoxide is heated with trimethylamine; (15) methyl cyclopentane is heated with trimethylamine; (16) tertiary butyl peroxide is heated with triethanolamine, dimethyl (isopropyl phenyl) alcohol, bis-(2-hydroxypropyl-2-) benzene and tertiary butyl alcohol being obtained respectively.  In example (3) acetophenone is also obtained.
