Patent GB-452122-A (GB)
Title: Improvements in the treatment of films, foils and the like
IPC: D06M15/09
Filed: 1935-02-16
Abstract: The tendency of foils, films, and similar materials having a surface of a water-resistant organic compound, to become electrified is reduced by applying to the foils a solution which contains a hygroscopic film-forming compound or a hygroscopic liquid of low volatility and which has a viscosity not substantially exceeding that of water and a lower surface tension than water.  Cellulose acetate, propionate, butyrate, or nitrate, or benzyl cellulose, or other water-resistant cellulose ester or ether foils, films, or sheets may be treated.  The process may be applied to foils such as regenerated cellulose foils which have been rendered waterproof by coating with nitrocellulose, or other waterproofing agent.  The process is useful in preventing electrification of the foils when passing through printing machines, envelope - making machines, and wrapping machines, or for readily dispersing any electrification set up.  The solution which is applied to the foils may contain an organic liquid such as ethyl alcohol which is of low surface tension and viscosity in p addition to the hygroscopic film-forming compound or liquid of low volatility in order to facilitate spreading of the solution over the foil.  The solution preferably contains water and a softening agent for the foil substance.  Glycerine, glycol, and other liquid aliphatic polyhydric alcohols may be used as the hygroscopic liquid ingredient.  Cellulose acetate foils may be treated with a composition consisting of ethylene glycol, ethyl alcohol, triacetin, and water.  Hygroscopic film-forming substances which may be used are water-soluble methyl cellulose, water-soluble cellulose acetate, cellulose esters or ethers of glycollic, lactic, tartaric, citric, glyceric, and other hydroxy carboxylic acids, cellulose ethers of glycols, glycerine, or other polyhydric alcohols such as oxyalkyl cellulose ethers, cellulose esters of oxalic, maleic, malic, tartaric, phthalic, and other poly-carboxylic acids.  The water-soluble cellulose derivative such as methyl cellulose may be used in very dilute aqueous solution such as 0,5 or 1 per cent concentration.  Glycol or glycerine and ethyl alcohol may also be present.  Other water-soluble highly polymeric film-forming substances may be used.  Water-soluble polyvinyl alcohol, partially esterified polyvinyl alcohol, polyvinyl esters or ethers with hydrophile radicles, and poly-acrylic acid are specified.  The solutions may be applied to the films by spraying, passage of the film through a bath, or in contact with a roller or other applying device. Rollers or doctor blades may be used to spread the solution uniformly and remove excess.

Patent GB-430764-A (GB)
Title: Improvements in the manufacture and production of vinyl ethers
IPC: C07C43/16
Filed: 1934-02-19
Abstract: Vinyl ethers are manufactured by causing acetylene to act at atmospheric pressure in the liquid phase on organic hydroxy compounds containing but one free alcoholic hydroxyl group which boil at a temperature below the reaction temperature, in a strongly alkaline medium, the concentration of the base used as catalyst and dissolved in the reaction liquid being so high that at the reaction temperature employed the solution still remains liquid under atmospheric pressure.  The reaction is advantageously carried out continuously in a reaction tower from which the vinyl ethers are continuously distilled, the unused acetylene being returned to the tower. Suitable catalysts are the oxides, hydroxides, alcoholates and phenolates of the alkali metals.  In examples: (1) acetylene is passed at the bottom and butyl alcohol at the top into a tower containing a solution of caustic potash in butyl alcohol at 126 DEG C., vinyl butyl ether being distilled off; (2) a solution of caustic potash in ethylene glycol monoethyl ether is similar treated at 150--160 DEG  C., yielding ethylene glycol ethyl vinyl ether. Specification 427,036 is referred to.

Abstract: 308,301. Farman, H., aud Farman, M., (trading as Farman, H. et M.), (Assignees of Waseige, C. R.). March 21, 1928, [Convention date]. Variable-speed epicyclic gearing.-A compressor for supplying combustible mixture to an internal-combustion engine used on aircraft is driven at one speed at high altitudes and at a lower speed at low altitudes. The high speed drive is through a friction clutch 4, 9, 10, Fig. 1, and an epicyclic train on to a pinion 43 on the compressor-rotor shaft. The epicyclic train comprises either a fixed annulus 42 and planet spur pinions 41 or a fixed bevel wheel 52, Fig. 3, and planetary gear consisting of pairs of bevel wheels 51 on spindles journaled in bearings carried by the driven member 9 of the clutch. The clutch is of the kind described in Specification 288,173; the driving member of the clutch consists of a plate 4, carried on a hollow spindle 5 keyed to an extension 3 of the crank shaft. The plate 4 lies between two friction surfaces one carried by the driven member 9 of the clutch, the other by a plate 10 keyed to the member 9. Weighted levers 11 on a disc 7 are lightly pressed by springs 15 against the plate 10, and under the action of centrifugal force close the clutch; it is opened by a fork 19 moving a sleeve 18, and thereby displacing levers 16 which bear on the projecting ends of the weighted levers 11. With the clutch open the low speed drive can take effect. In one form this consists of an internal ratchet wheel 54, Figs. 4 and 5, formed on the driving member 4 of the clutch and spring-pressed weighted pawls 55 carried by a ring 57 keyed to the pinion 43 on the compressor shaft. A direct drive is .thereby obtained; when the high speed drive is used this ratchet clutch at first over-runs and then the weighted ends of the pawls move the pawls out of gear. In the form shown in Fig. 1 a similar ratchet clutch is used, with an epicyclic speed-multiplying train; this comprises a fixed annulus 65, planetary pinions 64 carried by the driving member 4 of the clutch, and a sun pinion whose interior forms the ratchet. In a modification of this last arrangement the ratchet clutch is disposed between a fixed part of the casing and a sleeve which carries the annulus 65.

Title: Process of producing cyclodiene monomers from polymer-containing streams
IPC: C07C4/22
Filed: 1956-02-22
Abstract: <PICT:0807800/IV (b)/1> A process for the separation of C6 and C5 cyclodiene monomers from the effluent from a vapour phase cracking operation comprises quenching the effluent to 550-650 DEG  F., passing it through a primary fractionation zone from the overhead of which are obtained C5 and C6-cyclodiene polymers and copolymers, partially depolymerizing the latter to obtain monomers which are recovered and residual polymers and copolymers which are passed to the primary fractionation zone, where a substantial amount are depolymerized and the remainder are withdrawn with tars.  Hydrocarbon vapours which may be mixed with 50-90 mol. per cent of steam based on the hydrocarbon are cracked in the furnace 300, quenched to a temperature of 550-650 DEG  F. and led by line 3 to the primary fractionating zone 4 which employs pressures between 0 and 15 p.s.i.g.  An oil condensate collects on the plate 7 and is withdrawn to be used as a quench liquid. C1-C15 hydrocarbon vapours are removed by line 12, and water and heavier hydrocarbons (C10+) removed in the condenser 14 and may be refluxed to the fractionator or removed. The vapours are compressed to 40-210 p.s.i.g. and cooled to 90-135 DEG F. to liquefy most C5+ hydrocarbons in knock-out drum 21, C1-C4 vapours being removed through purifying system 28 where remaining C5-12 hydrocarbons are liquefied.  The liquid from 21 passes through the debutanizer 23, where C4-C6 hydrocarbons are separated.  These are mixed with the bottoms from 28 and dimerized in the soaker 30, unwanted C9- material being stripped in stripper 31, the dimers then being cracked, fractionated and recovered as monomers in the cracking zone fractionator 35 and 36.  Uncracked polymers are recycled through 43 or removed with other C6+ liquids recovered as bottoms from the debutanizer to the secondary cracking and recovery unit 46 and 47, the bottoms from the latter are recycled through 53 or returned to the primary fractionating zone 4 through 54 with uncracked polymer from zone 46.  Uncracked polymer from zone 35 and debutanizer 23 may be returned wholly or in part direct to the primary fractionator 4 through the by-pass line 56.  The residual fraction returned through 54 preferably forms 1-5 per cent by weight of the total hydrocarbons fed into 4, has a residence time therein of 5-10 seconds, and is introduced below the plate 7.
