Title: Improvements in or relating to catalytic hydrogenation
IPC: B01J23/44
Filed: 1954-06-07
Abstract: Alkylated or arylated anthraquinhydrones or anthraquinols are produced by reducing alkylated or arylated anthraquinones in a solvent medium by means of hydrogen in the presence of a catalyst comprising palladium deposited on titanium dioxide. The titanium dioxide is preferably hydrated or only partially dehydrated by heating to a temperature not greater than 1000 DEG C., and is preferably in the form of a hard gel which may be obtained either by precipitation from a titanium salt solution, e.g. titanium chloride or titanyl sulphate, with alkali followed by washing and drying or by coagulation of a colloidal solution of dispersed titanium dioxide by means of an alkali, and/or heating followed by washing and drying. The titanium dioxide is impregnated with a suitable solution of palladium, e.g. sodium chlorpalladite (Examples 1, 3 and 4), or palladium chloride (Example 2). In the latter example the impregnated carrier is treated with sodium hydroxide solution. The palladium salt may be reduced to palladium before or during the hydrogenation process. The solvent may be a two component mixture in which one component is cyclohexanyl acetate or propionate or methylcyclohexanyl acetate or propionate and the other component is benzene toluene or xylene. Specifications 465,070 508,081, 566,499, 686,574, [all in Group III], 718,305, 718,306, [Group III], and 718,307 are referred to.ALSO:In the production of hydrogen peroxide by the successive hydrogenation and oxidation of alkylated or arylated anthraquinones in solvent medium, the hydrogenation is carried out in the presence of a catalyst comprising palladium deposited on titanium dioxide.

Patent ES-318020-A1 (ES)
Title: Dense sodium carbonate
IPC: C01D7/12
Filed: 1965-09-30
Abstract: Dense Na2CO3 (i.e. bulk density about 60 lb./cu ft.) is made by reacting NaHCO3 (e.g. crude bicarbonate from the ammonia-soda process) with aq. NaOH (40-70% by wt.) such that Na2CO3 is formed as the stable phase thereafter changing the temperature and composition of the system such that Na2CO3.H2O is formed as the stable phase, which is separated and heated to give anhyd. dense Na2CO3. The reaction may be carried out in three ways:-(a) using NaOH in 10-15% excess of stoichiometric at 100-105 DEG C. to form Na2CO3, and then making Na2CO3.H2O the stable phase by lowering the temperature to 3-7 DEG C. below the transition temp. at which Na2CO3 and Na2-CO3-H2O are in equilibrium, which is at first about 97 DEG C. but is reduced as more Na2CO3.H2O is formed due to the increase in effective concentration of NaOH, again lowering the temperature below the transition temperature eventually forming the monohydrate completely (b) as (a) but conversion to monohydrate effected by successive additions of NaHCO3 stoichiometrically equivalent to the free NaOH at the transition temperature (c) reacting stoichiometric proportions of NaHCO3 and aqueous NaOH at 90 DEG C. at least and insulating the system against heat loss to enable the heat of the reaction to superheat it above 107.5 DEG C. to allow all the NaHCO3 to react to form Na2CO3, thereafter cooling to below 107.5 DEG C. whereby Na2CO3 is transformed into Na2CO3.H2O, which is separated and heated to yield dense Na2CO3.

Title: Process for the stripping of actinides contained in organic solvents with nitrous acid
IPC: C01G56/00
Filed: 1966-09-15
Abstract: Actinides, especially uranium, neptunium and plutonium, which have been extracted from nitric acid solutions into an organic solvent (preferably tributylhosphate or trilaurylamine in an inert diluent such as a hydrocarbon) are stripped from this solvent by nitrous acid. The nitrous acid is prepared in situ from sodium nitrite and nitric acid or by passing nitric oxide into dilute aqueous nitric acid maintained out of contact with air. In the examples the process is carried out in a bank of mixersettlers which is totally enclosed, the acid and organic solutions being introduced at opposite ends to give countercurrent conditions. Nitric oxide is continuously bubbled into the acid to maintain the nitrous acid concentration.

Title: Clarifying vessel for liquids
IPC: C02F1/52
Filed: 1967-08-21
Abstract: A clarifying vessel for removing impurities from liquids comprises, within an outer envelope 1, a compartment 4, 5 in which a fluidised bed, dirt agglomeration process is intended to occur, and a compartment 3 for classical filtration, whereby the liquid rises in the pre-treatment compartment, slows down owing to the increasing cross-section thereby avoiding entrainment of the agglomerated particles, and overflows into the filtration compartment over a weir 2. As described, compartment 4, 5 surrounds compartment 3 concentrically, and may be sub-divided by radial walls. Liquid enters through perforated pipes 10, 11 and after filtration through sand 9 enters a chamber 8. To keep clean the material 13 of the fluidised bed, it is circulated by a pump 15 through a hydrocyclone 17 which removes the agglomerated particles. A gutter 19 is provided for discharging the washing water. Specification 1200364 is referred to.

Abstract: Facsimile signals are time division multiplexed with a television signal during the vertical blanking period. As described, the facsimile signals are included during the intervals between the horizontal synchronizing pulses which follow the second group of equalizing pulses in the vertical blanking period of a negative modulation television signal. A generator 24, Fig. 2, provides sync. signals for a conventional TV system including a camera 23 and a facsimile scanner unit 25 is controlled by the generator 24 via a timing device 27 and provides signals from a document 26 which are converted at 28 into one or zero bits indicating black or white respectively. The output of coder 28 is supplied via an AND gate 29 to a buffer 30 where it is fed in at a relatively slow rate and read out at a high rate under the control of clock 31 via AND gate 40 and OR gate 60. The output of clock 31 is counted down at 34 to control the quantizer clock 36. The clock 36 via a control circuit 37 enables the AND gate 29. The AND gate 40 is enabled by a signal from a start burst detector 102 at the end of the second equalizing pulse group of the vertical blanking signal. The output of the buffer 30 is supplied via a video gate 42 to a transmission line 22. The receiver, Fig. 2A (not shown), operates in a converse manner and may be in the form of an adapter arranged to be plugged into a TV receiver at a point where the synchronizing signal is available.
