Title: Improvements relating to an apparatus for stretching synthetic fibres
IPC: B65H51/10
Filed: 1965-05-11
Abstract: 1,101,735. Apparatus for stretching filaments. BARMER MASCHINENFABRIK A.G. 11 May, 1965 [13 May, 1964], No. 19836/65. Heading B5B. An apparatus for stretching individual or groups or bundles of synthetic threads running side by side by means of endless conveyer bands looped round rotatable rollers, comprises clamping regions both at the input and a delivery end of the apparatus each formed by an endless conveyer band tensioned against and by means of a pressure roller, the pressure roller acting on the outer surface of the band between two deflecting rollers of the band, and the two bands rotating at different speeds. One or both of the deflecting rollers of a conveyer band may be swingable or displaceable on a common support. The deflecting rollers may be supported by a yielding coupling member, and the pressure roller may be arranged to be swingable or displaceable. In addition a counter roller may be arranged to act on the conveyer band. The conveyer band may be driven by one or both deflecting rollers or by the pressure roller or the counter roller or both. In the apparatus of Fig. 1, a thread line 1 passes over roller 19 and thence into the neck formed by roller 10 and conveyer band 8. Conveyer band 8 is mounted over deflecting rollers 4 and 5, and the pressure roller 10 is adjustable in the direction of conveyer band 8 by the action of the piston rod 13 of the hydraulic loading device 14 in the frame 12. The thread line then passes between the nip formed by roller 11 at belt 9. Tensioning roller 11 is mounted in fixed position in frame 15 while conveyer band 19 with its two deflecting rollers 6 and 7 and its support 16 is displaceable relative to framework 15 by the action of piston rod 17 of the hydraulic loading device 18 acting on support 16. Conveyer band 8 may be driven by one or both deflecting rollers 4 and 5, and conveyer band 9 may be driven by tensioning roller 11. Fig. 2, illustrates an arrangement in which the entering and leaving thread lines are parallel. The apparatus of Fig. 3 illustrates an arrangement in which the deflecting rollers 26 and 27 of conveyer band 29 which is in contact with pressure roller 28 are displaceable in swivel arms or in slot guides indicated at 30 and 31 respectively. By this means in the event of the conveyer band undergoing an increase in length the deflecting rollers are kept in direct contact with the pressure roller through the tensioned conveyer band. Fig. 4 shows an arrangement similar to Fig. 1, but with an additional counter roller on the frame, this counter roller acting on a conveyer band from outside and being, if necessary, displaceable in the direction of the conveyer band. A similar arrangement is shown in Fig. 5, in which deflecting rollers 4 and 5 are connected together through a spring supported coupling link 33 and can be arranged to be pushed together so that one of the rollers, i.e. roller 4, can be brought into direct contact with pressure roller 10 and, if desired, also with counter roller 32, through the conveyer band.

Title: Process for the manufacture of alkylated phenols and their hydrogenation products
IPC: C07C37/52
Filed: 1928-07-17
Abstract: 320,638. Williams, W. P., (Schering Kahlbaum Akt.-Ges.). July 17, 1928. Phenols; cyclohexanols.-Alkylphenols and the corresponding cyclohexanols are prepared by treating a dioxydiphenylmethane with hydrogen, either at a temperature above the point of decomposition in the presence of a normal hydrogenation catalyst or at a temperature below the point of decomposition with the further addition of a catalyst of porous structure. The alkylenephenols which are produced by the thermal decomposition (see Specification 304,727) are thereby simultaneously hydrogenated to the corresponding alkylphenols or cyclohexanols. Some cyclohexanols may be formed when the hydrogenation does not proceed to completion. Porous catalysts mentioned are fuller's earth, diatomite, silica gel, tonsil, and frankonite (a Registered Trade Mark); additions of half to one per cent to the normal hydrogenation catalyst are sufficient. According to the examples, (1) pisopropylphenol and phenol are formed by heating 4 : 4-dioxydiphenyldimethylmethane with hydrogen under pressure at 250-280‹ C. in the presence of nickel, or at 170-180‹ C. in the presence of both nickel and tonsil; by continuing the treatment, a mixture of 4-isopropylcyclohexanol, cyclohexanol, 4-isopropylcyclohexanone and cyclohexanone is obtained; (2) thymol and m-cresol are produced by hydrogenating 4 : 4<1>-dimethyl-2: 2<1>- dioxydiphenyldimethylmethane (see Specification 308,741) at 215-220‹ C. with nickel, or at 140-150‹ C. using nickel and tonsil, or at 130- 140‹ C. using a nickel-cobalt copper catalyst precipitated on frankonite; a mixture of stereoisomeric menthols and menthones with 3-methylcyclohexanol and 3-methylcyclohexanone results on further treatment; (3) p-ethylphenol and phenol are obtained by treatment of 4 : 4-dioxydiphenylmethylmethane with hydrogen under pressure at 150‹ C. in the presence of a nickel-cobalt-copper catalyst precipitated on frankonite until two atomic proportions of hydrogen are absorbed; similar treatment of 4: 4<1>-dioxydiphenylmethane until no hydrogen is taken up yields a mixture of 4-methylcyclohexanol and cyclohexanol. Specifications 254,753. and 274,439 also are referred to.
