Title: Improvements relating to the spinning of yarns from slivers of bast and long leaf fibres
IPC: D01H13/18
Filed: 1945-05-22
Abstract: 592,643. Spinning directly from sliver rolls. MACKIE & SONS, Ltd., J., and MACKIE, J. P. May 22, 1945, No. 12785. [Class 120 (i)] In a spinning frame for the direct conversion of slivers of bast and long-leaf fibres into yarn, the slivers are drawn from rolls mounted for rotation in creels, and the rotation of each sliver roll is caused to cease when a stop motion comes into action on breakage of the yarn being formed from that sliver roll. In one embodiment, Fig. 2, a sliver roll 16, which is mounted above the frame in pivoted creel members 32, rests on and is peripherally driven by pressing retaining roller 3. When the yarn breaks, a stop motion of the kind described in Specification 425,612 causes cam 24 to engage arm 38, moving roller 3 out of contact with driving roller 2. In another embodiment, Fig. 4, sliver roll 16 rests on fixed creel members 32 in driving contact with roller 42. Operation of the stop motion causes rod 54 to engage lever 46, so that the serrated projection 50 engages the sliver roll, stopping rotation thereof and moving it out of contact with roller 42. Lever 46 may also be hand operated. In a further embodiment, Fig. 8, the sliver roll is supported on two driving rollers 66, and a different stop motion is used. , On yarn breakage, detector 20 swings, bringing pawl 76 into contact with rotating ratchet wheel 74. Lever 72 is thereby moved to the right, causing lever 78 to move upwardly to lift the sliver roll out of engagement with rollers 66. Alternative arrangements are shown for disengaging the sliver roll from its driving rollers. According to other embodiments, the sliver roll may be peripherally driven by an endless belt or may be rotated by the pull on the sliver. In the latter case, the roll may be arranged so that the distance between the nip of the retaining rollers and the point where the sliver leaves the roll is less than the average staple length of the fibres, and the roll may be mounted in antifriction bearings with a light brake to prevent over-running. In further embodiments, the roll is positively stopped on yarn breakage by engagement with a pointed rod, or by the interposition of a plate between the roll and its driving roller. Alternatively, the stop motion may be arranged to declutch the drive to the roller driving the sliver roll. Where fixed creel arms are used, the outer ends of the arms may be notched so as to support a reserve sliver roll. Specifications 407,690 and 509,493 also are referred to.

Title: Manufacture of aryloxy-alkylamino butanones and butanols
IPC: C07D295/108
Filed: 1941-10-07
Abstract: 552,454. Aryloxy-alkylamino butanones. GEIGY AKT.-GES., J. R. Oct. 7, 1941, No. 12937. Convention date, Oct. 8, 1940. [Class 2 (iii)] Aryloxy-alkylamino butanones are prepared by first condensing a monovalent phenol or a derivative of a polyvalent phenol containing only one hydroxyl group with a monohalogen acetone and then treating the aryloxy acetone so produced with a hydroxymethylamine, In place of the hydroxymethylamine there may be employed the reaction mixture obtained from formaldehyde and a primary or a secondary amine. The butanones thus obtained may be reduced to the corresponding butanols. In examples (1) Monochloracetone is condensed with o-cresol in the presence of sodium hydroxide and the o-cresoxyacetone so produced treated with the crude condensation product obtained by reacting piperidine with formaldehyde. The resulting o-cresoxybutanonyl-piperidine 1- (2<SP>1</SP> - methylphenoxy - 1') - 4 - piperidyl - butanone-2 is purified by distillation. (2) A benzene solution of o-cresoxyacetone is treated with diethylamine to give 1-(2<SP>1</SP>-methyl-phenoxy- 1<SP>1</SP>) - 4 - diethylaminobutanone - 2. Similarly using #-naphthol in place of cresol the corresponding #-naphthoxy compound is obtained. (3) Guaiacoxy-acetone from guaiacol and monochloracetone is reacted with the crude condensation product of formaldehyde and piperidine to give 1-(2<SP>1</SP>-methoxyphenoxy-1<SP>1</SP>)-4- piperidyl-butanone 2. (4) The condensation product of morpholine and formaldehyde is reacted with methoxyphenoxy-acetone to give 1 - (21 - methoxyphenoxy - 1<SP>1</SP>) - 4 - morpholinyl - butanone-2. (5) o-Benzyloxyphenoxy acetone prepared by treating pyro-catechine mono-benzyl ether with monochloracetone in the presence of sodium hydroxide is added to a cold mixture of piperidine, formaldehyde, benzene and sodium chloride to give 1-(21-benzyloxyphenoxy)-4-piperidyl-butanone-2. The free amino phenol may be obtained by acid hydrolysis. (6) Benzyloxyphenoxy acetone is added to the reaction mixture of methylcyclohexylamine and formaldehyde and worked up as in example (5) to give 1-(2'-benzyloxyphenoxy) - 4 - (methylcyclohexylamino) - butanone-2. The free amino-phenol is obtained by acid hydrolysis. (7) o-Benzyloxyphenoxyacetone prepared as in example (5) are added to a benzene solution of morpholine, formaldehyde and sodium chloride to give 1-(21- benzyloxyphenoxy-1<SP>1</SP>)-4-morpholinyl-butanone- 2. The amino ketone is reduced by sodium in alcohol to form 1-(2<SP>1</SP>-hydroxyphenoxy- 1<SP>1</SP>)-4-morpholinyl-butanone-2. (8) Phenoxyacetone in benzene solution is added to morpholine and formaldehyde to form 1- phenoxy-4-morpholinyl-butanone-2. The corresponding 1 - phenoxy - 4 - morpholinyl - butanol-2 is obtained by reduction of the ketone by sodium in alcohol.

Title: Improvements in or relating to a method and apparatus for averaging a succession of electrical transients
IPC: G01S7/292
Filed: 1964-03-26
Abstract: 1,057,892. Selective signalling. NUCLEAR DATA Ltd. March 26, 1964 [March 27, 1963; July 9, 1963], No. 12965/64. Heading G4H. In a system for extracting an approximation to a cycle waveform from a background of random noise, each cycle of the wave is divided into a plurality of channels or time slots and the amplitude of the wave within each channel is measured digitally by a process which effectively averages the amplitudes within a particular channel over a succession of cycles. The digitizing process is basically to compare successive amplitudes in a particular channel (all of which would be the same but for noise) with a different reference voltage selected from a set of 2n reference voltages- Vn, - Vn-1, . . . - V1, +V1, +V2, . . . +Vn-1, +Vn, in such a way that after 2n comparisons every reference voltage has been used once, and to add or subtract unity to a counter each time the unknown amplitude is larger or smaller, respectively, than the reference voltage. The final count will then be a measure of the average value of the amplitude with a particular channel over 2n successive cycles. In the detailed embodiment each cycle is divided into 256 channels, each having its own associated counter, each channel is divided into four subchannels so that four comparisons with four different reference voltages can be effected in each cycle of the wave, and the wave is integrated (by an R-C circuit with a suitably small time-constant) over each sub-channel being used in a comparison. Then the 128 comparison with 128 different reference voltages (- 64 to +64) are effected in 32 cycles, and the final counts of the 128 counters represent an approximation to the cyclic wave-form. The contents of the counters may then be converted into analogue form and used to produce a display of the wave-form on an oscilloscope. Block drawings of the system are given and a detailed circuit (Fig. 4, not shown) is given for producing a sequence of reference voltages using weighted resistors.

Abstract: 1,200,322. Composite materials. DUNLOP CO. Ltd. 15 March, 1968 [21 March, 1967], No. 13076/67. Addition to 1,039,861. Headings C3C and C3R. [Also in Division Dl] Composite materials are prepared by introducing into an assembly of fibres first a liquid composition which is one part of a polyurethane foam forming mixture and subsequently a vapour which is the complementary part of the polyurethane foam-forming mixture, allowing the liquid composition and vapour to react to form a polyurethane foam within the assembly of fibres and then subjecting the composite material to reticulation. The liquid composition suitably contains a polyurethane prepolymer and the vapour may comprise an amine catalyst or preferably steam. In examples the assembly of fibres is in the form of a fibrous web consisting of crimped nylon filaments, a fibrous web prepared from rayon staple fibre by cross-lapping a carded web of the fibres and a fibrous web produced by processing polypropylene staple fibre on a carding machine followed by cross-lapping and passing through a needle punching machine. The fibrous assemblies may be compressed or moulded during or after foaming. An assembly of fibres may comprise two fibrous webs superimposed one upon the other, and the structure obtained when the polyurethane foam-forming reaction has taken place may then be separated into two layers corresponding to the original two webs, the layers obtained being treated again individually in accordance with the invention. The fibres may be moulded during foaming between an impervious surface and a porous surface. Reticulation may be achieved by inserting the cellular material into a combustion chamber, replacing the air in the chamber by an explosive gaseous medium and igniting the medium so as to generate sufficient heat to remove substantially all the thin walls or membranes of the cellular material.

Abstract: <PICT:0590554/III/1> In rotary apparatus for treating fluids, which may operate as the stripping section of a fractionator, and in which the denser fluid is impelled by centrifugal force from the rotor hub to the periphery, while the lighter fluid flows from the periphery to the hub, through a common annular zig-zag passage formed by a number of annular partition walls extending alternately from the opposite lateral walls of the rotor, the passage has locally restricted sections and means are provided for conducting denser fluid separately from wider parts of the passage to narrower parts nearer the rotor periphery; transfer takes place either from the lighter fluid to the denser fluid, or vice versa, according to the use to which this apparatus is put.  The Figure shows in longitudinal section one half of a fractionator wherein a spindle 1 mounted in a stationary casing 2 carries a high speed rotor 3 having concentric conical walls 18, 181 extending alternately from its sides.  The denser fluid from an inlet 7, and annual passage 71, is fed to the innermost contacting zone 13 by an impeller 11 through tubes 12 and a slot 14 (interrupted over the tube ends), and is finally removed through an outlet 8. The lighter fluid passing from inlet 9 to outlet 10 is assisted by fan blades 22 on the rotor casing.  Each section of the annular passage is narrowed by a fillet 24 to effect increased velocity in the contacting zones 13, 15 through which the fluids pass in temporary co-current flow.  A conical extension 25, 251 on the end of each annular wall defines two separating zones into the troughs 23, 231 of which the denser fluid is flung by centrifugal force, whence it is led, respectively directly and through tubes 20, to a narrow channel 16, between the fillet and the next annular wall, communicating with the next contacting zone through a slot 17 between the end of that annular wall and its extension.
