Title: An improved process and apparatus for washing and aftertreating freshly spun cakes of artificial silk
IPC: D01D10/04
Filed: 1931-05-20
Abstract: <PICT:0364489/IV/1> <PICT:0364489/IV/2> <PICT:0364489/IV/3> Spun cakes of artificial silk are arranged on holding devices, and together with the holding devices are attached to an endless belt or an endless chain and passed through spraying, trickling, or immersion baths.  They are thereby subjected to all or part of the necessary liquid treatments such as washing, desulphurizing, decoppering, acidifying, bleaching, or vivifying.  As shown in the drawings, the cakes are placed on rods 16, 17 and carried by a conveying chain 8 in an undulating path through the various parts of the after-treating devices.  They are carried through immersion vats 10 and sprinkling baths 11 arranged above the vats 10.  In order to lead back the liquid draining from the cakes into the proper vat, inclined draining surfaces 12 are arranged.  The cakes may be tied up or bound with skein threads, or may be wrapped up in permeable jackets such as knitted tubes.  After having passed through all the treatment baths, the cakes are removed from the chain and may be centrifuged and dried.  As shown in Figs. 2 and 3, the conveyer is in the form of a double chain, the two parts of which are joined together at each link by tie rods 13.  The chain is positively driven by a pair of star-shaped members 18 rigidly connected together by a common rotation shaft 19.  Claw members 20 on the star wheels engage with the tie rods 13 at both sides. The cakes are placed side by side on pairs of rods 16, 17, which project into the associated chain-members b<1>, b<2>.  The chain-members are provided with apertures, slits, notches, and devices for preventing the rods 16, 17 from falling out. The Specification as open to inspection under Sect. 91 (3) (a) also describes a method in which the cakes are placed without supporting devices on a horizontally moving conveyer belt which carries them through dripping baths.  This subject-matter does not appear in the Specification as accepted.

Title: Hydrogenation of a solid carbonaceous material
Inventor: SELLERS FREDERICK BURTON
IPC: C10G1/08
Filed: 1956-05-14
Abstract: In a process for the hydrogenation of solid carbonaceous material, particles of the solid smaller than 1/4 inch in diameter are mixed with a hydrogenation catalyst and a liquid vaporizable at 250-1500 DEG  F. and 50-5000 p.s.i.g., the mixture is passed through a heating zone to vaporize the liquid and form a dispersion of solid particles in the vapour flowing at a velocity above 25 feet per second thereby pulverizing the solid (see Group II) and the solid particles and catalyst are separated from the vapour and subjected to reaction with hydrogen under hydrogenating conditions.  The solid may be anthracite, bituminous coal, lignite or oil-shale and the vaporizable liquid is preferably water or a light hydrocarbon.  The slurry of liquid and solid is passed into an externally heated tubular coil at 1-10 feet per second to give a dispersion flowing at 25-3000 feet per second.  The whole of the liquid is preferably vaporized.  After separation, e.g. in a cyclone separator, the solid is hydrogenated. The solid may be mixed with an oil, e.g. part of the product, and subjected to liquid phase hydrogenation at 3000-10,000 p.s.i.g. and 600-900 DEG  F. in the presence of 2000-80,000 standard cubic feet of hydrogen per ton of coal using residence times of one minute to several e.g. three hours.  Dry hydrogenation can be carried out with similar conditions apart from a slightly lower pressure.  The coal particles are preferably fluidized.  Suitable catalysts include the oxides, sulphides and nitrides of titanium, tin, copper, lead, zinc, chromium, cobalt, iron and alkali and rare earth metals, stannous oxalate and ferrous sulphate.  Where the catalyst is soluble in the vaporizable liquid it may be dissolved therein.  Specification 683,318, [Group II], is referred to.

Patent GB-581518-A (GB)
Title: Water-repellency agents
IPC: C07D213/20
Filed: 1944-08-18
Abstract: Quaternary ammonium compounds of the formul  R-CO-NH-CH2-N(tert)-X or R-O-CO-NH-CH2-N(tert)-X, wherein R is an aliphatic hydrocarbon radical containing an alkyl chain of 21 or 22 carbon atoms, N(tert) stands for an aliphatic or heterocyclic tertiary amine, and X stands for the anion of a water-soluble acid, are prepared by reacting the methylol compound R-CO-NH-CH2OH or R-O-CO-NH-CH2OH with the salt of a tertiary amine N(tert).HX, preferably in presence of an excess of the tertiary amine.  Such compounds synthesized for example from docosyl carbamate (C22H45OCONH2) or behenic acid amide (C21H43CONH2) impart to textile fibres water repellency effects of greater permanence than do similar compounds wherein R has an alkyl chain of different length, described in Specifications 475,170 and 498,287.  The tertiary amine is preferably a heterocyclic amine, e.g. pyridine or a homologue or quinoline, a trialkylamine having less than six carbon atoms or an alkylene polyamine having less than six carbon atoms per basic nitrogen atom.  The methylol derivative may be prepared from, for example, behenamide, and formaldehyde in a basic medium and in presence of an alkaline-reacting substance such as potassium hydroxide, sodium carbonate or pyridine, and then reacted with a salt of the amine with, for example, hydrochloric, hydrobromic, sulphuric, nitric, thiocyanic, sulphurous, oxalic, formic, acetic, glycollic, citric, salicylic, chloracetic, sulphanilic or phthalic acid.  With polybasic acids, the residual acidity is neutralized by additional tertiary base. The methylol compound may be made in situ by bringing together the amide, formaldehyde, and amine salt in presence of excess amine.  Reagents supplying formaldehyde, e.g. trioxymethylene or paraformaldehyde, may be employed, and procedure varied as in the prior Specifications referred to.  In examples: (1) behenamide is reacted with formalin in presence of ethanol and caustic soda to give the methylolamide which is treated in pyridine with pyridine hydrochloride at 60 DEG  C. yielding behenamidomethyl-pyridinium chloride.  Fabric impregnated with 1 per cent thereof from an aqueous alcoholic solution, followed by heating to 150 DEG  C. is water-repellent after repeated dry-cleaning and laundering; (2) behenamide, paraformaldehyde, pyridine and a petroleum solvent are heated at 90 DEG  C., hydrogen chloride is added to convert 80 per cent of the pyridine to the hydrochloride, and the quaternary compound formed used for treating cotton, wool, rayon, silk and nylon; (3) docosyl carbamate is reacted similarly and the product used on cotton jean cloth.  Pyridine in these examples may be replaced by picoline, quinoline, mixed pyridine bases, trimethylamine, methyl - diethylamine, tetramethyl - ethylene (or methylene) diamine.

Title: Improvements in or relating to leather or like splitting, skiving or like machines
IPC: C14B1/14
Filed: 1923-06-19
Abstract: 221,865. British United Shoe Machinery Co., Ltd., Gouldbourn, J., Ricks, F., and Minett, W. T. June 19,1923. Splitting - apparatus. - Relates to machines with power-operated rolls for feeding only part of the length of a work-piece past the knife and comprises : (1) means for putting the machine at different times in a condition for starting the operation on a work-piece and a condition for stopping the operation, and '(2) the provision in machines having gapped feed rolls of a device which automatically moves the rolls apart to release the work. The work is fed to a stationary knife 4 by rolls 2, 3, the former being adjustable vertically through a wedge member by a hand-wheel 7, while the latter is urged upwards by springs 5. The upper roll 2 has a flat face 32 which is parallel to the work-piece when cams 33 on the ends of the rolls contact to separate the rolls. The rolls are geared together and are rotated from a shaft 11 through gear-wheels and a keyed sliding member 16 connected to a lever 19, which, when turned in one direction engages clutch faces on the sliding member and a pulley 14, and applies a brake when turned in the other direction. The lever 19 has a spring-urged tailpiece 21 connected to a treadle and carries a notch 22 co-operating with a plate 23 on a spring- urged arm 24 pivoted on a pin 25 to the frame. On the arm 24 is a cam roller 26 which co-operates with an adjustable cam 27 on one of the gearwheels 8 and a cam 28 on an arm 39 adjustably secured to the upper roll shaft by a nut 31. Both of the cams can actuate the arm 24 to stop the machine, the cam 27 being arranged to stop the machine when the flat face of the upper roll is parallel to the work-piece, the cam 28 performing a similar function when the concentric portions of the rolls are in contact. To, split a sole without completely severing the flap, the heel end of the sole is presented to the bite of the rolls and the treadle is depressed; the piece is then split and the rolls stopped by the cam 27 with the flat 32 facing the workpiece and the rolls separated by the cams 33. The work-piece is then drawn back from the knife and the clutch again closed to return the rolls to starting position. To completely sever a flap from the sole the machine is stopped with the rolls separated and the flat facing the work-piece and the piece is inserted from the knife side of the rolls to project forwardly of the knife for a distance equal to the length of flap to be severed; the treadle is then depressed and the sole is fed back through the machine and the flap severed. In completely severing a gap the cam 28 is not used and may be swung about the axis of the upper roll into engagement with a recess in the trailing end of the cam 27.
