Title: Improvements in the method of drying oxidizable fatty oils and paints, varnishes andresins prepared therefrom
IPC: C09F9/00
Filed: 1930-09-09
Abstract: The drying of oxidizable fatty oils or paints, varnishes, and resins derived therefrom is accelerated by incorporating therein polyvalent metal compounds of ketonic mono-basic organic acids having the general formula R-CO-R<1>-COOH in which R<1> represents an aromatic nucleus and R analkyl, aryl, cycloaromatic, polynuclear or heterocyclic radical, a carbon atom of which is attached directly to the carbon atom of the ketonic group.  The compounds are incorporated in the oils by dissolving at ordinary or elevated temperature, or by first dissolving in aromatic hydrocarbons, followed by mixing with the oil, when no separation occurs.  Oils referred to are linseed, tung, soya bean, rape seed, fish oils, drying oil fatty acids such as linolic, linoleic, oleostearic, and paints, varnishes and other compositions prepared therefrom together with pigments, natural or synthetic gums or resins, or cellulose derivatives.  The metallic salts may also be employed to accelerate the hardening of synthetic resins derived from drying oil acids, polyhydric alcohols, and polybasic acids. The following metals are specified: cadmium, chromium, tin, mercury, copper, aluminium, zinc, iron, manganese, cobalt, lead, vanadium, thorium, uranium, nickel, thallium, and rare earth metals and numerous ketonic acids, especially p-cymoyl-o-benzoic acid and the preparation of some such acids by condensing phthalic anhydride with naphthalene, tetrahydronaphthalene, p-dichlorobenzene, pinene, ethylbenzene, diphenylene oxide, diphenyl ether and butyric anhydride is described. The condensation of isophthalic and terephthalic dichlorides to form similar ketonic acids is referred to, and as substituents halogen, nitro, or alkyl groups may replace nuclear hydrogen in any of these compounds.  The polyvalent metal salts of aromatic ketonic acids are obtained by double decomposition of water-soluble salts of the acids with soluble salts of polyvalent metals or by fusion of the solid acids with a metal oxide, hydroxide, or carbonate.ALSO:Ketonic monobasic acids are obtained by condensation between phthalic anhydride or its nuclear substituted derivatives and isophthalic or terephthalic dichlorides with any organic group containing a replaceable hydrogen atom.  Many suitable aliphatic, aromatic mono- and polynuclear and heterocyclic compounds are referred to.  Examples are given in which the condensation of phthalic anhydride with naphthalene, tetrahydronaphthalene, p-dichlorobenzene, pinene, ethyl benzene, diphenylene oxide, diphenyl ether, and butyric anhydride is described.  The polyvalent metal salts of the resulting acids may be employed to accelerate the drying of fatty oils, or may be incorporated in resins derived from oxidizable fatty acids, polyhydric alcohols, and polybasic acids, in order to accelerate the hardening of such resins.

Title: Desulfurization of hydrocarbons and mixtures of hydrocarbons
IPC: C10G45/10
Filed: 1955-09-23
Abstract: Hydrocarbons are desulphurized by contacting in the vapour phase with 100-10,000 S.C.F./B. of hydrogen, at a temperature of 340-940 DEG F., a pressure of 15-600 p.s.i.g. and a space velocity of 0.1-20 v./v./hr., in the presence of platinum dispersed or impregnated on a catalyst support.  The mol. ratio of sulphur to platinum in the contact zone is maintained at 1.5 : 1 to 3 : 1 and the mol. ratio of sulphur to hydrogen at such a value that: <FORM:0793817/III/1> where Tr is the temperature of the zone in degrees Rankine.  The catalyst support may be alumina, silica gel or activated charcoal. The catalysts may contain from 0.05-2 per cent platinum.  The catalyst may be used in the form of a fixed bed (where the particles may be of 1/16 -\ba3/8 in. diameter), a moving bed (particles of 1/8 -\ba1/16 in. diameter) or a fluidized bed (particles of 20-150 microns diameter).  The hydrogen used may be pure hydrogen or hydrogen containing light paraffinic hydrocarbons such as methane and ethane, e.g. tail gas from hydroforming operations.  The hydrocarbons may contain aromatic and/or olefinic compounds, and may be, for example, petroleum naphtha fractions boiling from 200-380 DEG  F., derived from cracking and/or coking processes, e.g. catalytic cracking; or petroleum distillates boiling from 150-400 DEG  F.  The ratio of platinum to sulphur in the reaction zone may be adjusted by passing therethrough a sulphur-containing gas, e.g. hydrogen containing hydrogen sulphide, or a sulphur-containing hydrocarbon such as the feedstock itself; this presulphiding reaction may be carried out at at least 400 DEG  F., a pressure of at least 15 p.s.i.g., a hydrocarbon feed rate of 1-10 v./v./hr. and in the presence of at least 1000 S.C.F./B. hydrogen.  The hydrocarbons are separated from the gases, which may be scrubbed with alkaline materials, e.g. aqueous sodium carbonate, caustic alkali or lime, or treated with diethanolamine, to remove hydrogen sulphide.  An example is given of the treatment of a mixture containing 1/3 benzene, 2/3 heptane and 0.5 vol. per cent thiophene.
Patent GB-318646-A (GB)
IPC: D01F2/28
Filed: 1929-09-07
Abstract: 318,646. I. G. Farbenindustrie Akt.- Ges. Sept. 7, 1928, [Convention date]. Grant of Patent opposed. Cellulose carboxylates, processes for making filaments from.-Artlficial silk threads prepared from solutions of organic esters of celluloses, particularly primary solutions thereof, are treated after leaving the spinning bath with a swelling agent and subjected to tension. As swelling agents, there may be used, for example, dilute formic or acetic acids, or solutions of zinc chloride or thiocyanates. The treatment may be conducted by passing the threads after leaving the coagulating bath over a roller, galette. or spool with a low speed of drawing and then, if desired, with a reduced velocity over further rollers in a bath containing the swelling agent and finally winding the threads with increased velocity on to a spool, galette, or reel, in such a manner that the stretching takes place between the rollers in the swelling bath. Alternatively, the threads can be led over glass rods and guides or through a channel, in which they are rinsed with the swelling agent and which also serves as a guide for the threads and can be so arranged that in the winding of the threads on to a spool or reel, it effects a to and fro movement which enables cross-winding to be effected. The swelling bath may alternatively comprise a trough with slits through which the threads pass in and out or the threads may only be sprinkled with the swelling agent while they pass over a roller or galette, or they may be passed after the drawing spool around a galette dipping into the swelling bath and then wound on tc a second spool revolving with a greater velocity. The continued action of the swelling agent may be prevented by running the winding apparatus in water or in a hardening bath or in a bath for effecting a subsequent treatment of the thread, or it may be sprinkled with these liquids. In an example an 8-10 per cent solution of cellulose acetate. prepared in known manner with sulphuric acid as catalyst and) subsequently hydrolyzed and treated to remove, the catalyst, is spun into a saturated solution of ammonium acetate; the thread is drawn at a speed of 8 metres per minute, and is then passed over a galette having a velocity of 8-10 metres per minute at the circumference and revolving in a swelling bath 1-8 metres long containing acetic acid of 3 per cent strength. The threads pass at the end of the swelling bath over a second galette at a drawing speed of about 20 metres and are finally wound on to a spool at a, speed of 25 metres. The silk obtained has a strength of 250 grams per 100 deniers and a titre of 3 deniers. Specification 309,558 is referred to.

Title: Improvements relating to ultra-short wave oscillators
IPC: H01J25/38
Filed: 1949-10-25
Abstract: 672,292. Travelling-wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Oct. 25, 1949 [Nov. 19, 1948], No. 27427/49. Class 39 (i). A travelling-wave tube has a delay line in two sections, the first section being an oscillator of relatively small length to give a wide electronic tuning band and a gain greater than unity and provided with an external feed-back channel and the second dimensioned to give an optimum power factor value. In Fig. 1, the helix H is in two parts, the first section A<SP>1</SP> of which is associated with a feed-back channel R containing a phase shifter D and a filter B, the length being adjusted by wave-guide sections L, L<SP>1</SP> containing pistons. The gain of section A<SP>1</SP> is higher than the critical gain for maintaining oscillations so that excess of power is supplied to the second section A<SP>2</SP> which has optimum conditions, e.g. length, and excess of gain, for power amplification. The section A<SP>2</SP> is coupled at one end to the section A<SP>1</SP> by the union of the helices and at the other end to a wave-guide S. In a modification (Fig. 2, not shown), the two parts of the line H have a gap between them and are decoupled by two grids with an absorptive attenuator adjacent these grids to absorb the reflected wave. Alternatively, a portion of wave-guide section with a cut-off lower than the transmitted wave-length. connects the two helical sections, the H.F. coupling being electronic. In Fig. 4, the wave-length section P is of greater length and forms a drift space, giving a higher modulation at the entrance to helical section H<SP>2</SP>. Here again an absorptive attenuator A is provided. Specification 667,208, [Group XL (c)], is referred to.

Abstract: 954,550. Nuclear magnetic resonance apparatus. BARRINGER RESEARCH Ltd. Aug.10, 1960 [March 4,1960], No. 27658/60. Heading G1N. In a nuclear magnetic resonance magnetometer the precession frequency is multiplied and the number of cycles in a predetermined period of time is counted. The period of time may be chosen to have a duration inversely proportional to the multiplication factor and the gyromagnetic ratio of the sample (water or a light hydrocarbon) whereby the count gives a reading in convenient magnetic units. The use of a 102,186 kc./s quartz crystal as a time period control oscillator to give a field strength measurement of 5 gammas (10<SP>-5</SP> gauss) per count is described. The signal from nuclear resonance apparatus 10 Fig. 1, is applied through narrow pass-band comb filters 18- 21, Fig. 2, having pass-bands of less than 10% of the centre frequency and being connected in pairs, to signal amplitude responsive transistor gates 22,23, and cascade transistor rectifier stages; Fig. 6 (not shown), shown in Fig. 2 as blocks 24,25 which effect multiplication. The gates 22, 23 which comprise a pair of differentially connected emitter followers 38,39, Fig. 4 to which the two filter outputs are applied via transistor rectifiers 34,35 and integrating circuits 36,37, permit the passage of only the stronger signal the higher rectified voltage causing one of the transistors 38, 39 to monopolise the total current through resistor 40. The signals are applied to the gates over isolation resistors 41,42. A similar gate 26 passes only the stronger multiplier output to a time gate 13 controlled by a programmer 15 and crystal reference oscillator 14, the programmer 15 in the case of free precession controlling the cut-off of the polarising field. A decade counter 16 responsive to the gated multiplied signals may feed an analogue voltage from each decade to a separate trace pen on a recorder 17. The production of field contour maps by aircraft is referred to and a subtraction gate arrangement for excluding from the count a predetermined number of cycles to compensate for diurnal variations is described with reference to Fig. 7 (not shown).

Title: Improvements in or relating to methods of making gel-forming composition and resulting product
IPC: C08L5/06
Filed: 1952-11-04
Abstract: In preparing edible jellies, there is employed a composition obtained by drying an aqueous solution or paste of a partially demethoxylated pectin which is reactive with calcium ions and has a methoxyl content of 2-7 per cent, a monovalent metal salt of a weak acid and/or a monovalent metal salt of either a complex acid of phosphorous or ethylene diamine tetraacetic acid.  A dry powder which forms the jelly merely on addition of cold water comprises a mixture of such dried solution or paste and a calcium salt having a limited solubility in water e.g. calcium sulphate, citrate, mono-, di- or tribasic phosphate, carbonate, or tartrate, the particles of the calcium salt being preferably coated with cold water-dispersible substance, e.g. casein, gelatine, methyl cellulose, carboxymethyl cellulose, locust bean gum, gum karaya, polyvinyl alcohol.  The particle size of the components of the mixture is preferably less than 0,009 in.  Examples of the coating of the calcium salts are concerned with spray-drying a hot water suspension of tricalcium phosphate stirred with low viscosity methyl cellulose and a hot water suspension of gypsum stirred with low viscosity carboxymethyl cellulose.  Such coated granules may be treated further in order to prevent too rapid access of water to the calcium salt in incompletely coated granules during the gel formation, e.g. the granules may be stirred with hot water, hot ethanol containing hydroxylamine hydrochloride, or hot ammonium tartrate solution, filtered off, and dried in hot air.  Examples of preparing the modified low methoxyl pectin are concerned with drum-drying or spray-drying hot water solutions of alkali-hydrolyzed citrus pectins to which sodium hexametaphosphate and sodium acetate or sodium citrate have been added, the alkali hydrolyzed pectin being, if desired, a "pectinic acid amide" obtained by the partial demethoxylation of pectin with alcoholic ammonia or concentrated aqueous ammonia. Examples of jelly preparations which set in 5-15 minutes are mixtures of (a) modified low methoxyl pectin, a coated calcium salt, sugar, citric acid, and, if desired, colouring matter and fruit flavouring, stirred into cold water.

Abstract: 783,971. Fuel injection pumps. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Sept. 27, 1954, No. 27892/54. Class 102(1). [Also in Group XXIV] In a fuel-injection pump, the inlet port 58 is controlled by the pump piston 42 and the delivery passes through a control valve comprising a ball valve 46 co-operating with a seat 45 and urged upwardly by a spring 49 into contact with a valve 47 which has a portion 53 that is a sliding fit in a guide bore 52. The output of the pump is controlled by a throttle valve 54 in the pump inlet and the amount actually injected is controlled by the unloading effect of the portion 53 on the outlet 41 which is adjustable by varying the thickness of the shims 73. In a modification, the portion 53 has a clearance with the bore 52 which results in the unloading effect increases with increasing engine speed. Fig. 2 shows an arrangement in which the pump piston 42 has an axial bore that communicates with the inlet 58 through a port 80 and is fitted with a valve 77, loaded by a spring 79, which controls the flow to the pump working chamber. The control valve 53 is in the form of a disc having a clearance fit in the guide 50 and is loaded by a spring 48. At the end of the delivery stroke, the valve 77 contacts the valve 53 and the amount of unloading of the outlet 41 is determined by the lift of the valve 53. This lift may be varied by adjusting the length of the tappet by a pinion 81 which by means of pins 82 turns the threaded member 69 in the sleeve 64. The piston may be actuated by a cam as shown in Fig. 4 in which the portion B<SP>1</SP> gives a slow movement of the piston in the direction of delivery, following the suction stroke, to control the filling of the cylinder. In a multi-cylinder pump, the suction portions of the cams are arranged so that suction takes place into only one cylinder at a time. Fig. 27 shows an arrangement for adjusting the pinions 81 of a multi-cylinder pump. A shaft 102 has circumferentially-spaced toothed segments so that by rotation of the shaft any one, or all the pinions may be engaged so that the shaft may then be moved axially by the threaded sleeve 112 to make an adjustment. Rotation of the shaft 102 is transmitted by gearing 110, 111 to a locking shaft 106 also having circumferentially spaced toothed segments so that any, or all, of the pinions may be engaged and locked.
