Title: Improvements in or relating to producing crystalline lactulose
IPC: A23L27/30
Filed: 1957-03-07
Abstract: Production of a crystalline lactulose product of at least 80% lactulose content entails heating a solution of lactose of pH greater than 5 at a temperature between room temperature and 150 DEG  C., separating the unconverted lactose, oxidizing the residue with bromine and separating the acids formed.  According to an example, a lactose solution treated with calcium hydroxide is heated at 100-102 DEG  C. for 15 min., and is allowed to cool; after 2 days, crystallized lactose is filtered off, the liquid is concentrated and further lactose is filtered off; the filtrate is diluted and sodium bromide is added; the resulting solution is electrolyzed, using graphite electrodes, until aldoses are no longer detectable chromatographically; during the bromine oxidation, calcium carbonate is added to neutralize the acids formed, and, after the oxidation, the product is passed over cation and anion exchangers, the solution obtained is concentrated in vacuo and is further dehydrated by treating with, and distilling off, methanol, the lactulose being finally allowed to crystallize out.  Specification 761,866 also is referred to.

Title: Improvements in or relating to a method of producing sodium aluminate solutions
IPC: C01F7/0633
Filed: 1932-07-08
Abstract: In the production of sodium aluminate solutions by digesting silica-containing oxides or hydrates of aluminium such as bauxite with preferably concentrated sodium hydroxide solution containing sodium carbonate, the digesting is performed in the presence of such a quantity of the oxides or hydroxides of barium, calcium, strontium, magnesium, zinc or mixtures thereof that not only is silica precipitated, but also not less of the carbon dioxide present than that which has been absorbed by the lye during the process.  The lye should contain less than 14 per cent of sodium p  carbonate reckoned on the total soda present.  Thereby, crystallization of sodium carbonate during concentration of the lye is prevented.  The bases, and sodium carbonate necessary to replace small quantities of sodium hydroxide lost are preferably added to the extraction kier.  Barium, strontium and calcium hydroxides should be used as a dried slaked powder, and may be mixed with the bauxite.  Zinc may be used as a burnt oxide.  An example relates to the use of slaked burnt dolomite.

Title: Improvements relating to the production of catalysts
IPC: B01J21/04
Filed: 1953-08-19
Abstract: Catalyst containing cobalt, molybdenum, and fluorine incorporated with an alumina support is prepared by adding cobalt, molybdenum, and fluorine compounds to wet alumina gel, which is then dried and roasted to decompose the compounds.  Suitable compounds are molybdic acid, cobalt formate, chloride or nitrate, and hydrofluoric acid or aluminium fluorides.  A suitable roasting temperature is 550 DEG C. Before use the catalyst may be reduced by heating in hydrogen or hydrogen sulphide, e.g. at 780 DEG F. and 100 lbs. per sq. in. pressure.  Examples describe the use of the catalyst for autofining a gas oil, with regeneration of the catalyst by means of a mixture of nitrogen and air, and addition of dichlorodifluoromethane or tertiary butyl fluoride to the feedstock.

Title: Process for the production of sulphinyl ethyl thiophosphates
Inventor: HEATH DENNIS FREDERICK
IPC: C07F9/165
Filed: 1954-07-12
Abstract: Sulphinyl compounds having the general formul (RO)(R1O)P(O)S.C2H4S(O)R11 wherei the R's represent alkyl groups, the same or different, containing not more than 4 carbon atoms are prepared by reacting a salt of a thiophosphoric acid of the formula (RO)(R1O) P(O)SH with a halo-alkyl sulphinyl ethane of the formula XC2H4S(O)R11 where X is an halogen and the R's are as defined above, preferably using equimolar amounts of the reagents.  The thiophosphoric acid salt may be used in admixture with a salt of the tautomeric acid (RO)(R1O)P(S)OH, in which case the tautomeric compounds of the formula (RO) (R1O)P(S)OC2H4S(O)R11 are also formed. A solvent such as a lower aliphatic alcohol or ketone may be present. A reaction temperature of 70-80 DEG  C. is preferred.  The mixture of the two tautomers may be separated by partition chromatography; the compounds have insecticidal properties.  In the example: 1-bromo-2-ethyl sulphinyl ethane and the sodium salt of OO1 - diethyl - thiophosphate (obtained as described below) are refluxed in absolute ethanol; the product is isolated and subjected to partition chromatography using water and benzene or trichlorethylene, whereby 80 per cent of the product is shown to be the compound (C2H5O)2P(O)SC2H4S(O)C2H5\t and the remainder is believed to be the corresponding tautomeric compound.  In like manner there may be reacted OO1-dimethyl thiophosphoric acid N a salt with 1-bromo-2-methyl sulphinyl ethane, o-methyl-o1-ethyl thiophosphoric acid Na salt and 1-bromo-2-n-propyl sulphinyl ethane and OO1-diethyl thiophosphoric acid Na salt with 1-bromo-2-isopropyl sulphinyl ethane.  Other specified reagents are OO1-di-n or isopropyl thiophosphoric acid, 1-chloro-2-ethyl sulphinyl ethane and 1-bromo-2-n-butyl sulphinyl ethane.  Alkali metal salts of OO1-dialkyl thiophosphoric acids may be prepared in admixture with the corresponding tautomers by reacting PSCl3 with a single or two different alcohols ROH and R1OH to yield the dialkyl thiophosphoric acid chloride which is then reacted with an alkali metal hydroxide. In the example, (C2H5O)2PSCl is prepared from PSCl3 containing radio-active phosphorus and then treated with aqueous NaOH.  The halo-alkyl sulphinyl ethane reagents may be prepared by oxidation of the corresponding halo-alkyl mercapto ethanes with H2O2.  In the example, 100 vol. H2O2 is added dropwise to an acetone solution of bromo-ethyl mercapto ethane at 20-30 DEG  C. Specification 742,796 is referred to.

Abstract: 787,683. Positive clutches. FIAT SOC. PER AZIONI. July 15, 1955 [July 26, 1954], No. 20598/55. Class 80 (2). The impeller 1 and turbine 2 of a fluid coupling can be locked together by sliding axially a clutch sleeve 6 on a driven shaft 3 to engage its peripheral teeth 21 with teeth 22 on a clutch member 4 fast with the impeller, movement of a lever 8 fulcrumed at 16 causing the clutch engagement, a forked plate 31 adjustably secured to a housing 12 limiting the throw of the lever. To adjust the position of the clutch sleeve 6 on assembly of the clutch, the lever 8 is put into the disengaged position, when the slidable clutch sleeve 6 touches a packing member 26. A mark 36 is then made on the casing against a notch 33 at the edge of the plate 31, which is secured to the casing by screws 32 in a slot. A second notch 34 is provided on the edge of the plate 31, at a predetermined distance from the notch 33 such that sliding the plate 31 along until the reference mark 36 coincides with this second notch will cause the form arm 35 of the plate to pivot the lever 8, and withdraw the clutch sleeve 6 slightly from the packing member 26 to a correctly aligned position where it is also free of the clutch member 4. The plate 31 is then secured by the screws 32. The lever 8 has a forked end engaging a half-ring 9 sliding in a groove in the clutch sleeve 6, and is pivoted on operation of a handle 38 acting through a spring 23 and a link 14. The end faces of the clutch teeth 21, 22 are bevelled, so that if they are not correctly positioned when the control lever 38 is moved to engage them, the spring 23 is loaded and, as soon as relative rotation between the clutch members 4, 6 occurs, the spring then slides them into engagement. Lubricant is contained in a chamber 25 surrounding the clutch member, and is supplied thereto through gaps 24 from a housing 11, surrounding part of the lever 8 &c. and provided with a vent 30.
