Title: A gas generator for producing power gas under pressure for the supply of torpedo engines
IPC: F42B19/20
Filed: 1927-08-09
Abstract: 294,385. Perrin, R. Aug. 9, 1927. Generating combustion products under pressure. -In apparatus for the production of a motive fluid under pressure for use in torpedo engines, of the kind in which liquid fuel and air or oxygen are supplied to a combustion-chamber and a cooling medium is introduced into the resulting gases, the fuel is supplied at a plurality of points between the air inlet and the outlet of the generator. As shown in Fig. 1, the casing 1 is divided by partitions 5, 6, having central apertures, into compartments 2, 3, 4, the former two being fitted with thin walls 10, 17 which converge downwardly into restricted necks 11, 20, and are spaced from the casing 1 to provide communicating combustion chambers surrounded by annular spaces 12, 18. A perforated distributing-plate 8 is disposed between the air inlet 7 and the first combustion chamber 2, liquid fuel, such as methyl or ethyl alcohol, being supplied at 9 and 15. The latter supply enters, through orfices 13, the annular space 12 in which it is preheated, being delivered into the gas stream passing through the neck 11 through openings 16. The cooling fluid, which is supplied at 23 and preheated in the space 18 before passing through holes 24 in the neck 20, is a fuel, preferably the same as that supplied at 9 and 15. The spaces 12, 18 may contain a catalyst for assisting the decomposition of the fuel into hydrogen, methane, &c. The chamber 3 may be omitted, the fuel supplied at 16 in this case serving both to complete the combustion and to cool the gases before they pass through the outlet 25 to the engine. Modifications are described in which the apertures 16, instead of delivering the additional fuel directly into the gases from the chamber 2, open into a hollow perforated member disposed in the neck 11. Fig. 5 shows a further construction in which the additional fuel is preheated in a coiled tube 32 disposed in close contact with the wall 1 and having perforations 34 for supplying the fuel to the restricted channel connecting the chambers 1, 4.

Title: Production of metallic articles
IPC: B21D22/20
Filed: 1974-05-13
Abstract: 1456050 Working superplastic alloys BRITISH ALUMINIUM CO Ltd 9 May 1975 [13 May 1974] 21061/74 Headings B3V B3Q [Also in Division C7] An article is formed from a blank of a superplastic alloy without prior conditioning of the blank to exhibit superplasticity by raising the blank to a forming temperature, applying force thereto at said temperature to deform it non- superplastically and induce dynamic strain recrystallisation, and continuing the application of said force so that a fine recrystallized grain structure is progressively developed and the blank is deformed superplastically to form the article. As exemplified aluminium alloy sheet is formed against a die by pressure, but it is believed that the process is also applicable to alloys predominantly of Cu, Ni, Zn and Mg, and to working by slow forging from rolled, extruded or cast starting material. The aluminium alloy preferably includes one or more of Cu, Zn, Mg, Mn, Si, Li and Fe to encourage recrystallisation and at least one of Zr, Nb, Ta and Ni in an amount of at least 0À25 per cent by weight substantially all of which is in solid solution to inhibit grain coarsening, the total of the latter elements not exceeding 1 per cent. Examples of suitable alloys are disclosed in Specifications 1,387,586 and 1,445,181 to which reference is made. Other suitable aluminium alloys are Al-10% Zn- 0-5% Zr, Al-6% Cu-0À5% Zr, Al-026% Zr-0À03% Fe-#0À01% Si-6À0% Cu. Forming temperatures of 380-580 C., forming times, grain sizes of 5-300 and various strain rates are referred to.
Patent GB-397295-A (GB)
Title: Improvements in and relating to catalysts
IPC: B01J37/02
Filed: 1932-07-26
Abstract: A nickel catalyst is prepared by mixing nickel oxide with a silicon ester, decomposing the ester and subjecting the mixture to the action of heat in a reducing atmosphere.  In an example, nickel oxide prepared from the carbonate is mixed with a toluene solution of ethyl orthosilicate and ammonium hydroxide added to effect coagulation. The product is broken up into granules, dried and reduced in a stream of hydrogen.  The catalyst may be used for the hydrogenation of cotton seed oil.  Since the granules settle rapidly, the hydrogenated oil may be poured off and replaced quickly by a fresh batch.  The nickel-silicon oxide catalyst may be attached to supports, e.g. a gauge of suitable mesh, the silicon ester causing the necessary adhesion.

Title: Recycle hydroisomerization process
IPC: C07C5/27
Filed: 1957-07-10
Abstract: Isopentane is prepared by the hydroisomerization of n-pentane over a platinum on alumina catalyst at 315-540 DEG  C., 1.4-140 kg. per sq. cm. gauge, an L.H.S.V. of at least one and with hydrogen in an amount less than 4 mols. per mol. of hydrocarbon, but greater than that at which the catalyst is rapidly deactivated and the effluent is fractionated into a product fraction rich in isopentane and a fraction rich in n-pentane containing hydrocarbons of higher boiling point than n-pentane which is recycled, the amount of higher boiling hydrocarbons recycled being such that the proportion of such hydrocarbons in the hydrocarbon feed stream is less than 3 mol. per cent.  In one method the isomerizer effluent after gases have been separated is passed to one or more fractionating columns from which there are recovered an isopentane fraction and a n-pentane bottoms fraction containing higher boiling constituents.  Part of this fraction is bled off and the remainder recycled and mixed with fresh feed which may be a straight run refinery pentane fraction; the amount of the n-pentane fraction bled off is preferably such that when the recycle and fresh feeds are combined they contain no more than 1.5 mole. per cent of material boiling higher than n-pentane. In a preferred embodiment the reaction effluent after separating gases is led with fresh feed to the fractionating columns from which there are obtained an isopentane fraction, and a n-pentane fraction containing the higher boiling material which fraction is further fractionated in the same or a different column to separate n-pentane from heavier materials.  The n-pentane fraction so obtained which is then isomerized may contain less than 0.5 mole. per cent of higher boiling material.  Instead of separating heavy materials from n-pentane by fractionation, other methods such as adsorption chromatography, molecular sieves or selective chemical treatments may be employed.  The hydroisomerization is preferably carried out as described in Specification 788,588.

Title: Improvements in and relating to analysis
Inventor: KENT THOMAS BRIAN
IPC: G01N30/34
Filed: 1960-06-22
Abstract: <PICT:0932664/III/1> A method of introducing a sample of a fluid to an analytical device comprises injecting predetermined volumes of the fluid at known intervals of time into a stream of a diluent fluid which is chemically inert to the sample, the rate of flow of the stream at any time being known, passing the resulting stream containing the injected fluid through at least one mixing vessel and subsequently introducing a measured sample of the mixed fluids to an analytical device.  The method is especially useful in chromatography.  The fluid sample and the diluent may be liquid or gas.  The diluent may be nitrogen or argon when the method is used in gas chromatography.  As shown, a continuous stream of sample liquid A is introduced to a valve B of the type described in Specification 800,212 and passed to waste at C.  A diluent gas stream D also passes through valve B.  This valve is operated at regular intervals of time to transfer known volumes of the sample fluid into the diluent gas stream.  The diluent gas stream containing injected sample fluid passes through mixing vessels F and H in series and the mixed stream I then flows through a valve J similar to valve B and passes to waste at K.  A continous stream of carrier gas L passes through valve J and then through a chromatography column.  Valve J is operated once, and, if desired, at regular time intervals to inject a measured sample (or samples) of diluted original sample fluid from stream I into the carrier stream L.  The stage of injecting a sample of fluid into a diluent stream and then mixing may be repeated one or more times, a sample from the final mixed fluid then being introduced to the analytical device.
