Title: Process for the separation of thorium from lanthanons
Inventor: SHERRINGTON LEONARD GEORGE
IPC: C01F15/00
Filed: 1958-09-19
Abstract: In a process for separating thorium from rare earth metals a solution containing thorium, rare earth metals and sulphate ions is extracted with a solution in an organic solvent of an amine having an aliphatic chain containing 10 to 30 carbon atoms which will form a complex with the thorium and sulphate ions, the organic solvent extract is washed with an aqueous solution containing chloride and sulphate ions, and the thorium is then removed from the washed organic solvent extract by extraction with an aqueous solution containing ions which displace the thorium from the amine complex.  In an example monazite is heated with sulphuric acid, diluted with water, filtered, and the solution extracted with a branched chain amine of formula C20H41NH2 dissolved in xylene, the extract being washed with an aqueous solution of hydrochloric and sulphuric acids and then extracted with an aqueous solution of ammonium nitrate and nitric acid to obtain an aqueous solution of thorium sulphate.  Other amines containing 16 to 24 carbon atoms may be used, and the solvent may be kerosene, toluene or benzene.  The chloride and sulphate ions in the liquid used to wash the extract may be provided by dissolved salts, e.g. sodium chloride and sodium sulphate.  The thorium also may be displaced from the amine complex by using an aqueous solution of ammonium carbonate to obtain an aqueous solution of a complex thorium carbonate.

Patent GB-1353428-A (GB)
Title: Antiskid system
IPC: G01P15/16
Filed: 1972-06-29
Abstract: 1353428 Determining retardation ALFRED TEVES GmbH 29 June 1972 [2 July 1971] 30406/72 Heading G4H [Also in Division F2] The occurrence of a predetermined retardation of a wheel is determined by counting impulses proportional to wheel rotation in a first count up and count down run, the count up period being determined by the time taken by a second counter to count a predetermined number of oscillator pulses and the pulse flow to said second counter being interrupted during its count down so that, for the desired retardation, the counters reach zero together. The method is used in an antiskid system and the count up and count down are preferably performed by separate counters so that the first counter can be reset and immediately reused. The oscillator frequency is considerably higher than the sensor output pulse frequency. As shown diagrammatically, pulses from the wheel (fsensor) are applied to up counter NZ<SP>+</SP> and down counter NZ- and the oscillator pulses (fosz) are applied to up counter Z<SP>+</SP> and down counter Z-. The first sensor pulse initiates pulses to counter Z<SP>+</SP> and these continue until the count (which may start at zero or some other value GW 1 ) reaches TG 1 . The first sensor pulse after this stops both counters, transfers the values therein to the respective down counters which immediately start counting down and clears the up counters. The up cycle then restarts. If the wheel is being retarded, the down count in NZ- will take longer than the up count in NZ<SP>+</SP> and, if the counts are to reach zero at the same time, for a desired retardation, the pulse flow to counter Z- must be reduced. It is also necessary to compensate for overshooting the count TG 1  in counter Z + while waiting for the sensor pulse to stop the count. This is done by stopping m out of n pulses from the oscillator reaching counter Z- while the count in Z- is above TG 1  and when the count in NZ- is one. The values of m and n are different in these two parts of the count and may take several different values in steps for counts above TG 1 , e.g. at values KG 2 -KG 5  above TG 1 . Blocks V 2  generate a 1 output when the associated counter reaches zero. The outputs are fed directly (for V z Z<SP>-</SP>) and via an inverter REV (for V z NZ<SP>-</SP>) to an AND gate and a 1 output from this gate indicates excessive retardation and actuates the hydraulic control system to release the brakes.

Title: Method for washing liquid hydrocarbons from used solid adsorbents
Inventor: BODKIN ERNEST AARON
IPC: B01D15/02
Filed: 1956-10-08
Abstract: <PICT:0845551/III/1> In a continuous process for washing adsorbents of palpable particulate form (average dimensions about 0.0058 to 0.1850 inch) wherein the adsorbent is passed downwardly as a columnar mass through a confined zone in countercurrent to a solvent, the rate of withdrawal of the washed adsorbent is controlled to maintain a residence time in the washing zone of 0.2 to 5 hours and the rate of solvent introduction is controlled between 0.20 and 3.0 volumes of solvent per volume of adsorbent (in conjunction with the relative length to cross-sectional area of the columnar mass) to maintain the superficial velocity of the solvent through the columnar mass below that which would substantially disrupt the mass but above that defined by the equation <FORM:0845551/III/1> where U ft./hr. is the superficial viscosity; Zs centipoises is the solvent viscosity; So and Ss g./c.c. are the respective densities of the (adsorbed) oil and the solvent; D inches is the average adsorbent particle diameter; and F is the fraction of voids between the adsorbent particles (determined by pouring adsorbent into a cylindrical vessel without agitation). The adsorbents which are washed are those which have been used for treating liquid hydrocarbons such as mineral oils, particularly petroleum lubricating oils and lower boiling petroleum fractions, for the purpose of removing impurities or undesirable contaminants therefrom.  Fig. 1 is a diagrammatic flow sheet for a process wherein a hydrocarbon oil is treated with a columnar mass of solid adsorbent in treater 11 and the used adsorbent is washed with naphtha according to the invention in washer 22.  In a preferred embodiment the recovered oil and solvent is withdrawn upwardly through the liquid body (55) above the columnar mass (56) at a superficial velocity, Ud ft./hr. between <FORM:0845551/III/2> and <FORM:0845551/III/3> where Sa, St and SL g./c.c. are the apparent adsorbent density, true adsorbent density, and density of the liquid body respectively and Z centipoises is the viscosity of the liquid. A portion of the solvent may be introduced into line 21 via line 63 to cool the incoming adsorbent.  The upper section of washer 22 may be of greater cross-section than its lower section to compensate for the effect of the higher temperature therein on the superficial velocity.  Adsorbents mentioned are fuller's earth, bauxite, bentonite, bone char, charcoal, magnesium silicate, heat and acid activated kaolin, activated carbon, and synthetic silica and/or alumina gels.  Solvents suitable for use in washing the adsorbents are carbon tetrachloride n-heptane, n-octane, carbon disulphide and petroleum naphtha.  The processes of Specifications 770,392 and 804,632 are disclaimed. Specification 759,515 also is referred to.
