Title: Cellulose acetate compositions containing mixed volatile solvents
IPC: C08J3/09
Filed: 1930-03-29
Abstract: A film-forming composition comprises acetone soluble cellulose acetate dissolved in a mixture of 50 parts by weight of methyl acetate, 10-40 parts by weight of ethyl acetate and 40 to 10 parts of acetone.  The mixed solvents have a greater solvent power even for high viscosity cellulose acetates than the sum of the solvent powers of the ingredients when used separately.  Plastifiers such as monochloronaphthalene, triphenyl phosphate, tricresyl phosphate and substituted benzene and toluene sulphonamides may be incorporated with the solution.  A plastifier comprising triacetin with 10 per cent of monoacetin may be used.  In an example acetone soluble cellulose acetate in powdered, fibrous, or flake form is dissolved in from 3 to 5 times its weight of the mixed solvent with one-twentieth to one half of its weight of the mixed acetin plastifier.ALSO:A film-forming composition comprises acetone-soluble cellulose acetate dissolved in a mixture of 50 parts by weight of methyl acetate, 10-40 parts by weight of ethyl acetate, and 40-10 parts of acetone.

[Class 91] [Also in Group IV] The sulphur content of petroleum naphtha containing a relatively high quantity of sulphur (at least 0.2 per cent.) is reduced and a high quality motor fuel of improved anti-knock quality with decreased sulphur content is produced by treating the naphtha in the vapour state with hydrogen gas in contact with a catalyst comprising an oxide of a metal selected from the left-hand column of Group VI under temperature and pressure conditions and at a space velocity which permit the aliphatic hydrocarbons to be largely dehydrogenated and cyclized to aromatic hydrocarbons and to effect the separation of sulphur as an inorganic sulphide. The catalyst may be molybdenum or chromium oxide supported on activated alumina. A number of reactors arranged in parallel relationship manifolded with fluid inlets and outlets so that the catalyst in any reactor may be regenerated, may be used. A stationary or moving bed type of reactor may be used. Examples are given of the treatment of a naphtha stock of California origin blended with a cracked naphtha, and of a dehexanised, cracked California naphtha. Specification 549,570 is referred to.

Title: Improvements in or relating to the provision of temporary protective coatings on articles, for example shoe parts
IPC: A43D11/00
Filed: 1947-04-18
Abstract: <PICT:0632594/III/1> An article, e.g. a shoe part, is provided with a temporary protective coating of a synthetic resinous material by forcing from a receptacle a cold, pasty composition comprising a suspension of the material in a liquid which is a solvent for it substantially only at elevated temperatures, along a conduit to a spray gun, the composition being heated after passing along the conduit to convert it into a free-flowing solution which is sprayed on the article.  Cellulose derivatives, e.g. ethers, are included as synthetic resinous materials which also include polyvinyl alcohol and polyvinyl acetal (see Group IV (a)). Referring to Fig. 1, on pressing the trigger of the gun 35, part of the compressed air from 17 flows through the conduit 13 to force the composition out of the receptacle 9 through conduits 15 and 43 into the spray gun.  The pressure generated by the force-feed unit 11 is of the order of 900 lbs./square inch. Compressed air also flows through filter 47 and valve <PICT:0632594/III/2> 49 to the gun.  The composition passes along the passage 71 of the gun (Fig. 3) (see Group XXIX) where it is heated by the surrounding elements 83 and converted to a free-flowing solution which emerges from the nozzle 75 and is broken up into a spray by compressed air issuing from nozzle 87.  Specifications 538,203 and 560,491 are referred to.ALSO:Compositions comprising a synthetic resin or cellulose derivative dispersed in a liquid which is a solvent for it substantially only at elevated temperatures are sprayed on to articles to form protective coatings.

Title: Improvements in and relating to fluid flow meters actuated by pressure due to the velocity of flow
IPC: G01F1/37
Filed: 1917-07-20
Abstract: 142,142. British Thomson-Houston Co., (General Electric Co.). July 20, 1917. Multiple - indication apparatus; index hands.-Relates to different pressure gauges for Venturi, Pitot, and like fluid-flow meters, and consists in a particular mechanism whereby, in gas and vapour meters the main indication is corrected automatically for the absolute pressure of the fluid. The well 6, Fig. 1, of the U- tube is formed in the usual manner within a base 5, having a removable cover 7 carrying the central tube 9 with a liner 11 chosen to the required cross-section and communicating with the leading and trailing pressures by pipes 13, 14 respectively. A float 15 and rod 16 in the central tube rotate a pointer-actuating spindle 19, as they rise and fall, by means of a screw 17, Fig. 2, and pinion 18 acting in this case as a rack and pinion, the two parts being kept in mesh and the fioat-rod guided by means of an idle grooved wheel 25. Movement is conveyed to the indicating pointer 27 by a known arrangement of permanent magnets 26, 28. A correction of the reading to take account of the absolute pressure of the fluid metered is brought about by means of a Bourdon or other pressure gauge 56, subjected externally to the trailing pressure but communicating internally with the atmosphere by way of a pipe 57. As the float rises and falls it carries up and down pivots 47 engaging in side-slots of a forked lever 46 which is pivoted to a rigid bracket 45 and carries freely at its lower end parallel arms 40, 40a formed as arcs of circles and provided each with a slot. In one slot there runs a roller upon the end of a sliding rack-bar 35, guided by rollers 36, and engaging a pinion 31 feathered upon the float rod 16. Within the other slot is a roller 53 upon the end of a lever 51 rocked by the Bourdon gauge. The parts are so designed that the rise and fall of the float rod alters the position of the parallel circular arms to determine varying effects of movements of the Bourdon tube upon the rack bar 35, which, by rotating the float rod deflects the indicating-pointer by means of the screw and worm wheel 17. 18. The parts are set so that at no pressure-difference the arms 40, 40a are concentric with the pivot of the Bourdon gauge in order that a variation in absolute pressure of the fluid may produce no change in the indication, and also that for a specified absolute pressure the lever 51 and the rack bar are parallel, whereby a change in the pressure-difference only does not result in rotation of the float bar.

Patent GB-105504-A (GB)
IPC: G04B23/10
Abstract: 105,504. Wada, K. Sept. 16. 1916. Alarm, and like mechanism.-A device which sounds an alarm at regular and adjustable intervals, particularly for use in connexion with the stoking of boiler furnaces, has two clock trains. The main train a, b, c h is continuously driven and controlled by an escapement g, and serves to control the movement of a pointer t and of the secondary train i, j, k. This train controls the alarm. Normaliy the pointer is driven, against the action of a spring u tending to hold it against a stop B at the zero of a scale on a dial plate A, through a clutch comprising a pinion v mounted on a pivoted arm w, engaging the wheel h and normally held in gear with a wheel S on the pointer spindle by a spring y. The secondary train has a cam-disk C and ends'in a fly-vane o, the train being normally held at rest by one arm F of a pivoted T-lever D, which is held in the path of a projection p on the vane spindle by a spring E. In this position, one arm of the lever D rests in a depression in the cam, in which also rests one end of a lever J. As the pointer t approaches a fixed pointer N, a pin M on the wheel S engages the arm H of the lever D, which is thus moved to free the vane o. The secondary train then runs, and the cam operates the lever J, so that the other end of this lever, engaging the pivoted arm w, moves the pinion v out of engagement with the wheel S, and the pointer t flies back against the stop B. The lever J also closes contacts Q in the circuit of an alarm bell or other device. The cam rotates and the bell continues to ring until the levers D, J again enter the camdepression, whereupon the contacts Q open, the arm F arrests the vane o, and the pinion v moves back into engagement, so that the operation is repeated. The time-interval is adjusted by altering the relative position of the stop B and fixed pointer N, the dial A carrying the stop B being rotated by a rack and pinion operated by a knob R<1>. A train R may be added to count the num- Ler of times the contacts Q are closed.
