Patent GB-742784-A (GB)
Title: Process and apparatus for the continuous treatment of granular materials with liquids or liquids and gases
IPC: B01J8/20
Filed: 1951-12-05
Abstract: <PICT:0742784/III/1> Solid granular material is contacted with a liquid with or without a gas, the liquid having a specific gravity less than that of the granular material, by passing the material downwardly over perforated inclined surfaces in counter-current with the liquid or liquid and gas, the rate of flow of the latter being adjusted to cause the granular material to exert negligible pressure on the inclined surfaces without passing into the fluidized state. The flow of liquid may be intermittent and a mixture of granular solids may be used.  A suitable apparatus comprises a vessel 1 with inclined surfaces 12, 13, and a controllable discharge 4 for the solid granular materials.  Liquid enters at 8 and overflows at 9.  A gas may enter at 10 and pass through the perforated pipes.  Other modified constructions are disclosed and the use of pneumatic, optical and other control means for the regulation of the solids discharge is discussed. The liquid may comprise water or aqueous solutions, organic solvents or solutions of organic substances or colloidal suspensions and dispersions.  The process and apparatus of the invention can be used, e.g. for the extraction of solid materials with aqueous or organic solvents (in particular treating oil-seeds), chemical or physical reactions between the solid and liquid or solid/solid phases (if mixed granular material is used). The solid material may act as a catalyst.

Title: A delivery valve for pumps supplying liquid fuel to internal combustion engines
IPC: F02M59/46
Filed: 1951-12-05
Abstract: 709,837. Fuel-Injection pumps. VOZIDEL, U.M., and BOTTGER, J. Dec. 5, 1951 [Dec. 5, 1950], No. 28512/51. Class 102 (1). The delivery valve of a fuel-injection pump comprises a cylindrical member 2 lapped to fit the bore of a housing 1 The member 2 has a head pressed by a spring 3 against the end of the housing 1 and the sten of the member has an annular groove 4 which is intercepted by longi tudinal grooves 8 that taper towards the an nular groove and have open ends 9. The housing has an annular groove 5 which is connected by ports 10 to the delivery pipe leading to the engine cylinder. At low engine speeds the member 2 is lifted until the annular grooves coincide and lift of the member is determined by the minimum cross-section 6 of the grooves 8. As the engine speed increases, the lift of the member 2 increases and a larger crosssection of the grooves 8 is available for fuel flow. Taking into account the relief action on the fuel in the delivery pipe, the delivery valve results in the pump having a falling delivery characteristic with increasing speed. Reference has been directed by the Comptroller to Specification 673,107.

Title: Halogen-containing organo-tin compounds
IPC: C07F7/22
Filed: 1965-07-06
Abstract: Halogen-containing organo-tin compounds are prepared by reacting organo-tin-halohydrides with compounds having unsaturated groups (e.g. olefins, alkynes, aldehydes, ketones, unsaturated nitriles, Schiff's bases, and azo compounds) preferably in the presence of a radical producing catalyst (e.g. benzyl hyponitrile, azoisobutyric dinitrile or an azoisobutyric dialkyl ester) at less than 50 DEG  C. with or without a solvent in an inert atmosphere (N2).  Alkyl, aryl or aralkyl tin halohydrides of the formulae R2Sn(X)H,RSn(X)H2 or RSn(X2)H (preferably where R=C1-C8 alkyl or simple aryl, e.g. Ph) are prepared in situ from the corresponding organo-tin hydrides and organotin halides and may be reacted with the unsaturated compound to give organo-tin halohydrides with dissimilar organo-radicals and/or containing functional groups. The Sn-H group adds across the multiple bond.  The following compounds are among those prepared in the examples:  Ex. 2:  (isoBu)2Sn(Br)-CH2-CH2CN; Ex. 3: Ph2Sn(Cl)-CH2-CHMePh; Ex. 5: Ph2Sn(Cl)(CH2)6-Sn(Cl)Ph2; Ex. 6: (nBu)2Sn(Cl)(CH2)3O(CH2)2OH; Ex. 11: EtSn(Br)2CH=CHPh; Ex. 14: (isoBu)2Sn(F)(CH2)3OH; Ex. 16: (nBu)2Sn(Cl)-N(nBu)CH2Ph.

Title: Process for reacting gases or vapours in the presence of solid catalysts
IPC: B01J8/04
Filed: 1948-11-03
Abstract: <PICT:0654797/IV (b)/1> <PICT:0654797/IV (b)/2> Partial oxidation of organic compounds such as that of olefines to aldehydes, particularly propylene to acrolein and methylethylketone to diacetyl by means of oxygen are effected by passing one reactant continuously in contact with the whole of a catalyst whilst contacting the other reactant in admixture with the first reactant alternately with separate portions of the catalyst in turn, whereby each portion of the catalyst is periodically brought into equilibrium with the vapours of the first reactant.  In Fig. I, for example, oxygen enters between two separate portions of the catalyst at 2 whilst propylene is alternately passed up and down through both portions of the catalyst by means of valves 6 and 8.  Four separate catalyst chambers are preferred as shown in Fig. 8 wherein propylene, indicated by a heavy broken line, enters chamber 40 at 36 and passes through line 37 to meet the oxygen entering at 38, the propylene-oxygen mixture, indicated by heavy full lines, passes downwardly through chambers 41, 42, 43.  Periodically the incoming propylene is passed first up through chambers 40, 41, 42, 43 in turn and down through the other three.  Industrial oxygen of 90-98 per cent purity with an oxygen/propylene mol. ratio of 1 : 4 and reaction temperature and pressure of 620 DEG  F. and 115 p.s.i. are preferred, using a catalyst of copper oxide deposited on silicon carbide granules.ALSO:<PICT:0654797/III/1> <PICT:0654797/III/2> Catalytic reactions between two or more gases using a fixed catalyst are effected by passing one reactant continuously in contact with the whole of the catalyst whilst contacting the other reactants in admixture with the first reactant alternately with separate portions of the catalyst in turn, whereby each portion of the catalyst is periodically brought into equilibrium with the vapours of the first reactant.  The catalyst may be arranged in separate portions as in Fig. 1, the second reactant being introduced between the portions at 2 into the stream of the first reactant which by means of valves 6 and 8 is alternately passed upwardly and downwardly through both portions.  The process is suitable for hydrogenation using hydrogen as the second reactant, for example, of the product resulting from reacting an olefin with carbon monoxide and hydrogen, a cracked gasoline fraction may be purified by hydrogenation in an apparatus as in Fig. 7 wherein the gasoline preheated to 750 DEG  F. in the heater 20, and at about 900 p.s.i. pressure, passes through line 21 to the manifold 22 between separate chambers 23, 24 containing 5/16 inch pellets of zinc chromite catalyst.  Water gas, also preheated at 20, enters manifold 26 from line 25 and passes alternately up through chamber 23 or 24 and down through 24 or 23 by means of opening valves 29 and 28 or 27 and 30, respectively.  Multiple chambers in series may also be employed.

Title: New cinnoline derivatives
IPC: C07D403/12
Filed: 1948-11-05
Abstract: Mono- and diquaternary salts of pyrimidylamino-cinnolines of trypanocidal activity are obtained from a pyrimidine substituted in the 2-, 4- (or 6-) position by amino- or lower alkylamino, by a halogen or thioether in another of these positions, and by, optionally, a lower alkyl, amino or lower alkylamino in the remaining one of these positions, and a cinnoline substituted in 4-position by amino, and optionally by further alkyl, either the pyrimidine compound or both being in the form of their quaternary salts, by heating the reagents together in presence of acid.  The cinnoline compound may be employed in the form of a salt, or as a substance which will give rise to the amine under the conditions of reaction, such as an acyl derivative.  In examples, pyrimidines substituted in the 4-position by chlorine, bromine or iodine, or by methylthio, in the 2-position by amino, methylamino, and isopropylamino, and in the 6-position by methyl, ethyl or amino, are made to react with 6-aminocinnolines, having in the 4-position, amino, acetylamino, methylamino, and a further methyl group, in the form of methiodide quaternary salt or a free amine. The pyrimidine compounds are used in the form of methiodide. The reaction takes place on heating with or without hydrochloric acid and the products are dimethiodides, methiodide - hydriodides, and monomethiodides or hydrates thereof, &c., and may be converted into other di- or mono-quaternary salts or hydrates by exchange or action of alkali.  4 : 6 - diamino - cinnoline 1 - methiodide is obtained by quaternating the 6-nitro-4-amino-cinnoline, followed by reducing with iron and hydrochloric acid, and the corresponding base by the reduction of 6-nitro-4-aminocinnoline.  The base may be acetylated on the 6-amino group.  The corresponding 6-amino-4-methyl-amino compound is obtained by the action of methylamine hydrochloride on 6-nitro-4-phenoxycinnoline, converting to the quaternary salt the 4-methylamino derivative obtained and reducing the product.  The 6-amino-4-methyl-aminocinnoline base and the 3-methyl derivative are obtained by reduction of the 6-nitro compounds.  2 - Chloro - 4 - aminopyrimidine 1 - methiodide is obtained by quaternating the base.
