Abstract: 1295733 Heat-setting crimped tow POLYMER PROCESSING RESEARCH INSTITUTE Ltd 4 June 1970 [4 June 1969 7 June 1969] 27056/70 Heading D1F A method of heat-setting crimps in artificial fibres gathered into a tow and mechanically crimped comprises enveloping the crimped tow in a wrapping whilst feeding the tow and wrapping longitudinally, the tow being fed at a higher rate than the wrapping, increasing the density of the crimped tow in the wrapping by mechanical compression, and passing the wrapped tow longitudinally through a pressurized zone containing saturated steam at the annealing temperature of the fibre, the wrapping being guided over surfaces in the zone under tension so as to apply lateral pressure to the tow. In a preferred embodiment, a tow 1 of filaments, fibres or yarns, is passed vertically through a steam chamber 4 and then passed via guide rollers 6, 7, 8 to a stuffer-box crimper 10, an adjustable pressure being applied to the bottom wall of the crimper 10. The crimped tow 11 is then passed into a temporary storage container 12 from which it is overfed to a conduit 14. A wrapping 15, which may be a woven or knitted fabric is applied under tension around the crimped tow 11 at the entrance to the conduit 14, the wrapping being such that it extends one and a half times round the tow. The conduit 14 has a cross-section which decreases in area whereby the wrapped tow is compressed as it passes through the conduit. The compressed wrapped tow 19 is then passed via pressure seals 21 into a steam chamber 23 where it is fed several times round spaced rollers 24, 25, the axes of which are slightly skewed. The heat treated tow is drawn out of the steam chamber and the wrapping is removed for reuse after ironing. In a further embodiment, the wrapped tow follows a zigzag course about a vertical series of rollers in the steam chamber. The filaments of the tow may be temporarily straightened and cut to staple length. The fibres exhibit an enhanced permanence of crimp. Various examples of the annealing temperature ranges for certain synthetic polymers and artificial fibres are listed.

Abstract: 1295896 Boring tool holder REGIE NATIONALE DES USINES RENAULT 15 April 1970 [21 April 1969] 17898/70 Heading B3C A tool holder having an adjustable tool 0 comprises a body 1 formed as two elements, 1a which is connected to a spindle and 1b which carries the tool 0 and which is movable angularly about a hinge 1c against resilient forces. A push member 7 controls the adjustment of the tool 0 by acting on a lever 6 mounted in a hollow 1d of the body and engaging a pair of relatively radially closely spaced fulcrum points 8, 9 to produce a reduction ratio in the lever operation. In an alternative embodiment (Figs. 3, 4, not shown) the lever is formed with two blind passages (12), (13) which overlap to receive studs (18), (19) which provide the fulcrums. A wafer (14) of a plastics material is inserted between the ends of the studs to prevent friction sticking during adjustment. In a further embodiment (Fig. 5,-not shown) a second reducing ratio lever (36) is provided which is directly acted upon by the push member 7 and which is pivoted about trunnions (37) and carries a pin (39) which acts on the end of the primary lever (26). The trunnions (37) are carried on a rod (38) whose mounting includes a plastics ring (40) that provides temperature compensation for variations in the thickness of wafer (14) by moving the position of the trunnions (37).

Abstract: 1296745 Separating gas mixtures HOWEBAKER ENGS Inc 5 June 1970 [25 June 1969] 27420/70 Heading B1L Ammonia is separated from mixtures with hydrogen sulphide and/or carbon dioxide by contacting the gas stream with a substantially anhydrous phenolic liquid until the molar ratio of ammonia absorbed, to phenols present is 0.5-1.0, whereby the absorption of ammonia as compared with that of the hydrogen sulphide and/or carbon dioxide is preferentially increased. The process is suitably carried out at 70-175F countercurrently, the rich absorbent being heated to liberate the ammonia and regenerate the phenol which is then recycled. Since the gas mixture is generally at 70-130F and the phenolic liquid at 100-160F, the heat of reaction in the contact vessel is controlled, preferably to 95-175F, by recycling rich absorbent together with regenerated phenols. A suitable phenolic liquid consists of a mixture of phenol and the cresol isomers, but various other phenols may also be employed.

Abstract: 1312933 Hydrostatic transmission control JAPAN STEEL WORKS Ltd 7 Oct 1970 47714/70 Heading F2D In a control system for a hydrostatic transmission having a variable displacement pump 3 in a closed working circuit 8, 9 with a variable displacement motor 10 wherein manually controlled valve 36, 37 selectively supply control pressure to opposite sides of a piston 45 of a pump displacement servomotor 40 and supply control pressure through a shuttle valve 56 and fixed orifice 67 to a motor displacement adjusting the servomotor 58, an override control comprises a variable orifice 63 responsive to working circuit high pressure which opens the orifice when the working circuit pressure exceeds a predetermined value to reduce the control pressure supply to the motor adjusting servomotor 58 and thus increase motor displacement. Above the working circuit predetermined pressure the orifice 63 maintains the output torque constant. If, when the over-ride control has increased motor displacement to its maximum, the pressure in the working circuit rises beyond a second predetermined value it changes over a valve 69 which connects the control pressure supply to exhaust through an orifice 75 and thus reduces the control pressure supplied through the valve 36, 37 to the pump displacement adjusting the servomotor 40 to reduce pump displacement. The piston 45 of the pump displacement servomotor is biased by a spring 51 to its central, zero displacement position and the piston 60 of the motor displacement adjusting servomotor is biased by a spring 59 to its maximum displacement position. The pump 3, a make-up pump 4 and a control pressure pump 5 are driven from a common electric motor 1. Make-up liquid is supplied from the pump 4 through one-way valves 17, 18 to the low-pressure side of the working circuit. The working circuit is provided with a high-pressure relief valve 31. Relief valves 22, 80 determine the make-up and control pressures.

Abstract: 1333457 Distilling hydrocarbons ESSO RESEARCH & ENG CO 23 July 1971 34764/71 Heading C5E At least one component of a mixture is separated by contacting the mixture in a vaporized state in a fractionating tower with a host substance, that can form an adduct with the separable component, in solution in an inert solvent, which remains substantially liquid and in which the adduct is substantially insoluble, withdrawing as a bottom fraction a slurry of adduct and solvent, recovering the separable component from the adduct and withdrawing overhead non-adducted material. As shown a mixture of hexane and cyclohexane vapours is passed to fractionation column 3, equipped with vibrating trays, by line 4. A solution of thiourea in 2-methoxyethanol is passed to the column at a higher position by line 1. A fraction enriched in hexane is taken off by line 5 and cooled at 6. A slurry of cyclohexane-thiourea adduct in methoxyethanol is withdrawn at 7 and sent to tower 8 where the adduct is decomposed. A fraction enriched in cyclohexane is drawn off at 9, and thiourea solution is recycled by pump 10. Another adduct-forming agent referred to is urea; other solvents are alkoxyalkanols with up to 6 carbon atoms each in the alkyl and alkenyl radicals, or mixtures of these. The solvent may be miscible or not with the feed; the contacting is preferably under substantially anhydrous conditions. The process can be used to separate normal paraffins from branched-chain paraffins, naphthenes and aromatics.
