Patent GB-902148-A (GB)
Title: Improvements in and relating to the desulphurisation of hydrocarbon oils
Inventor: PEARCE THOMAS JAMES PERRETT
IPC: C10G67/08
Filed: 1958-08-22
Abstract: Hydrocarbon oil, substantially free from ethylenically or acetylenically unsaturated compounds, is desulphurized in a three-stage process, of which the first stage comprises treating the oil with sulphuric acid so that the temperature of the acid/oil mixture does not exceed 40 DEG  C., and/or passing the oil in vapour form over oxide of zinc, manganese or iron at 350 DEG -450 DEG C. and 1-50 atms. pressure so that at least 70% of the sulphur content of the oil is removed, the second stage comprises passing the vaporized oil, together with hydrogen, at 350 DEG -450 DEG C. and 1-50 atms. pressure, over a hydrodesulphurization catalyst, and the third stage comprises contacting the oil with a material which absorbs hydrogen sulphide.  The absorbent material employed in stage (3) may be oxide of zinc, manganese or iron, while the hydrodesulphurization catalyst of stage (2) may be palladium, platinum or cobalt molybdate (i.e. mixtures of oxides of cobalt and molybdenum as such or in combined form) supported on alumina. The three-stage process may be effected in one operation by passing the oil vapour, mixed with hydrogen, through a sandwich consisting of a bed of hydrodesulphurization catalyst between two beds each of which comprises oxide of zinc, manganese or iron. Where sulphuric acid treatment is employed, this may be followed by electrostatic separation of acid, washing with aqueous alkali (e.g. sodium hydroxide), electrostatic separation of alkali, and washing with water.  In examples, the proccess is applied to the desulphurization of straightrun naphtha.

Title: Flame resistant fabric construction
IPC: D06N7/04
Filed: 1975-06-30
Abstract: 1464698 Flock coated fire resistant fabric S GEORGE 30 June 1975 [1 July 1974] 27462/75 Heading B2E A flame-resistant fabric comprises a fibreglass base fabric coated with a polymeric adhesive in which flock fibres are so embedded that one end of the fibres is upstanding from the coating, the adhesive reacting to heat to block oxygen flow through the fabric and containing a plasticiser so distributed that plasticity is greatest adjacent the fabric surface. The distribution is achieved by coating the fabric with the plasticiser, e.g. with tricresylphosphate, by gravure roller, before application of the adhesive. The plasticiser coating thickness may be 5-20% of the adhesive thickness. As a result, the fabric yarns are elastically bonded and the adhesive tends to remain on the yarns and to leave voids. The flock, e.g. rayon, cotton, wool, nylon, polyester, may be applied electrostatically so that at least 50% of the flock length remains exposed. The fabric may be knitted or woven. Suitable adhesive compositions, which release gas on heating and are based on vinyl resins, are given. The adhesive may be cured after flocking.

Title: Process for the manufacture of esters of the leuco compounds of vat dyestuffs
IPC: C09B9/00
Filed: 1932-10-06
Abstract: Leuco compounds of vat dyes, esters of.--Sulphuric acid esters of leuco compounds of vat dyes are prepared by reducing the vat dye with alkali metal sulphides or polysulphides in the presence of a tertiary organic base with or without an organic diluent, and without isolation esterifying the reaction product by means of sulphur trioxide, or an agent containing the same or capable of yielding it under the conditions of working, the entire process being performed under substantially anhydrous conditions and in absence of oxygen. Alternatively the vat-dye may be suspended in the tertiary organic base, sulphur trioxide or the agent containing or yielding this under the working conditions and an alkali metal sulphide then added, and the mixture stirred or ground at 10-20 DEG  C., the process being effected under anhydrous conditions and in the absence of oxygen.  As suitable bases pyridine or its homologues, quinoline, hexahydrodimethylaniline are mentioned, and suitable organic diluents are chlorbenzene or o-dichlorbenzene; in many cases it is advantageous to add a small amount of a secondary heterocyclic base such as piperidine or hexahydroquinoline to facilitate reduction, while the presence of some methyl or ethyl alcohol increases the solubility of the alkali metal sulphide in the mixture.  Reduction is effected by means of the sodium or potassium sulphides or polysulphides at 10-70 DEG  C., and esterification at 10-60 DEG  C.; chlorsulphonic acid or esters or salts, fuming sulphuric acid are employed as well as sulphur trioxide, and preferably in presence of a tertiary organic base.  The esters may be isolated as their alkali metal salts.  In examples, the sulphuric acid esters of the leuco compounds of the following dyes are prepared: 5.7 : 5<1>.7<1>-tetrabromindigo, thioindigo, indigo, 7.7<1>-di-nitrothioindigo, 4-methyl-5-chloro-7-methoxy-2<1>-(4<1>-chlornaphthalene) -2-indolindigo, 6.6<1>-diethoxythioindigo, 5.6.7-trichlorthionaphthene-5<1>.7<1>-dichlorindoleindigo, dimethoxydibenzanthrone and 3.4.8.9.-dibenzopyrenequinone. Specifications 5122/07 and 6490/07, [both in Class 2, Acids and salts, Organic &c.], also are referred to.

Title: Improvements relating to engines of the slow combustion type
IPC: F02B19/02
Filed: 1922-10-13
Abstract: 187,237. Veyre, G. A. Oct. 13, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Cylinders receiving liquid fuel; water, supplying to cylinders.-In a four-stroke-cycle engine, each cylinder is provided with a separate combustion chamber which is charged with air or mixture from another cylinder in which the piston is making its compression stroke. In the fourcylinder engine shown, each of the combustion chambers 1 - - 4 is separated from the corresponding cylinder by a wall having a mechanically actuated valve m<1>, and is connected to another cylinder by a conduit provided with a mechanically-actuated valve c<2>. The cylinders are also provided with the usual inlet and exhaust valves a, e, and the combustion chambers are provided with inlets d' for the injection of fuel under pressure. The combustion chambers are lined with refractory material and filled with pieces of a porous refractory substance. In operation, the piston p<2> draws in air on the inlet stroke, and towards the end of the compression stroke the valve c<2> is opened and admits the air to the combustion chamber 1. At the same time, fuel is injected by a pump through the inlet d<1> and combustion takes place at constant volume during the next three piston strokes. The valve m<1> opens at the beginning of the power stroke of the piston p<1>, which takes place at the same time as the compression stroke of the piston p<2>. Towards the end of this power stroke the valve m<1> is closed at the same time as the opening of the valve c<2> in the second cylinder. Exhaust takes place in the usual way through the valve e. To prevent overheating of the combustion chambers, water is injected through inlets e<1> immediately after the admission of fuel. In modifications, the air is delivered to the combustion chamber of the cylinder in which the exhaust or the inlet stroke is being completed. In a single-cylinder engine, the piston compresses, the air through a valve such as c<1> into a storage reservoir, from which it is delivered into the combustion chamber through a controlled valve when the piston is at the end of the power stroke or later. Such a storage reservoir may also be employed in multicylinder engines, all the cylinders delivering into this reservoir, which is connected in turn to each of the combustion chambers. The engine is started by admitting a combustible mixture from a light-fuel carburettor through the inlet valves a and the mixture, is ignited in the combustion chambers by means of sparking plugs o, until the refractory material is sufficiently heated.
