Title: Improvements relating to processes and apparatus in which gases and fluidised solidsare brought into contact with one another
Inventor: BUREAU ALFRED CHARLES
IPC: C10K1/30
Filed: 1960-01-04
Abstract: <FORM:0902139/III/1> In a process in which solid particles are circulated in a circuit comprising two vessels in each of which they are fluidized by and react with under pressure a gas which should not mix with the gas in the other vessel, the solid particles in flowing from one p  vessel to the other pass through seals formed by solid particles fluidized by a gas inert to the solid particles circulating in a closed circuit.  The process may be one in which sulphur compounds are removed from a fuel gas by contact with iron oxide and in which sulphided iron oxide is regenerated by oxidation with air. In the arrangement shown in Fig. 1 fuel gas to be purified enters a vessel 1 at 8 and passes upwardly through superposed beds of iron oxide and purified gas is withdrawn at 9.  The oxide in the two upper beds is fresh oxide fed from a hopper 29 through a screw conveyer 30 and the oxide in the two lower beds is continuously circulated to and from a regeneration zone 10 wherein the sulphided oxide is fluidized and regenerated by air admitted at 13.  The temperatures in vessels 1 and 10 may be 350 DEG  C. and 750 DEG  C. respectively and the two vessels are maintained at substantially the same pressure.  Oxide is withdrawn from the lowermost bed in the vessel 1 through line 23 and passes to the regeneration zone via a tubular vessel 19 and lines 24 and 26. Oxide is returned to the vessel 1 via line 27, a tubular vessel 20 and line 28.  The oxide particles in vessels 19 and 20 are fluidized by an inert gas circulated by a blower 18, the circuit including a space 21 containing the feed hopper 29 and a vessel 16 which serves as a reservoir for the inert gas.  The pressure in the inert gas circulation system is maintained at the pressure prevailing in the vessels 1 and 10.  A blower 22 supplies additional inert gas to the vessel 16 when needed and the vessel 16 has a pressure relief valve 17.  Fresh oxide is fed to the hopper 29 from a vessel 32 through valve 38 and line 37.  The vessel 32 may be included in or isolated from the inert gas circulating system by valves 33 and 34. A valve 35 enables the vessel 32 to be purged by inert gas when fresh oxide has been added thereto.  A modification of the vessel 32 is shown in Fig. 2, inert gas is passed only through the oxide above a grate 40 when the vessel is traversed by inert gas during feeding of oxide to the hopper 29 in vessel 1.  Specification 902,138 is referred to.

A method of forming a lead anti-radiation shield of substantially uniform density, comprises forming a layer of molten lead in an enclosure, cooling the layer to solidify it progressively from beneath, determining the condition of the surface of the solidified lead covered by molten lead by probing through the molten lead, and controlling the rate and direction of cooling in accordance with the findings of the probing to maintain a progressively increasing and substantially uniform thickness of solidified lead over the whole area of the layer. Preferably more molten lead is added while the surface of said laver is still molten. The lead may be cast into an enclosure comprising separate side-walls 5-8 on a table 3, and the cooling controlled by means such as burners 18 and air or water blasts 20.

Abstract: 555,293. Iodine compounds. JACKSON, L. MELLERSH-. (Tyler Laboratories, Inc.). Jan. 16, 1942, No. 691. [Class 2 (iii)] [Also in Group VI] . An iodine compound of amino-acetic acid, the aqueous solution of which is a solvent for iodine, the solution being suitable for pharmaceutical and disinfectant purposes, is made by adding free iodine to an aqueous solution of amino-acetic acid, preferably in the presence of a small quantity of metallic iron. The ferric iodide produced from the iron may be removed by active carbon. For pharmaceutical purposes the acidity of the solution may be reduced by adding an alkaline salt such as an alkali bicarbonate, and potassium chloride, sodium chloride and sodium sulphate are preferably added. A strong alkali such as caustic soda should not be used to reduce the acidity when this is to be effected after iodine is dissolved in the solvent.

Title: New active platinum-group metal catalysts
IPC: B01J23/58
Filed: 1963-01-07
Abstract: Finely divided Pt, Pd, Rh, Ru, Os, or Ir, produced (see Division C7) by mixing a solution of the metal salt with a solution of an alkali or alkaline earth metal borohydride, is used as a catalyst in the hydrogenation of unsaturated hydrocarbons and in aromatization processes.  In an example, a solution of sodium borohydride in ethanol is added to an aqueous solution of chloroplatinic acid to generate the catalyst.  Concentrated hydrochloric acid is then added followed by 1-octene. Further sodium borohydride solution is added to generate hydrogen and effect the hydrogenation. In another example, the hydrogen is introduced from an external source.  Further examples refer to the use of the catalyst at 350 DEG  C. for the dehydrogenation of methylcyclohexane and n-heptane to produce toluene.ALSO:Finely divided Pt, Pd, Rh, Ru, Os, or Ir is produced by mixing a solution of a salt of the metal with a solution of an alkali metal or alkaline earth metal borohydride.  Metal salts referred to are rhodium chloride, ruthenium chloride, palladium chloride, osmic acid, iridium chloride, platinum chloride, sodium chloroplatinate and chloroplatinic acid.  Water or ethanol are suitable solvents for the metal salt and water or alcohol are suitable solvents for the borohydride. The finely divided metal may be used as a catalyst for the hydrogenation of unsaturated hydrocarbons and the dehydrogenation of saturated organic compounds (see Division C5).  The Specification also refers to the production of Mn, Fe, Co, Ni, or Cu by the addition of its chloride to an alkali metal borohydride.ALSO:A catalyst is prepared by impregnating a high surface area carbon or alumina support with a solution of a salt of Pt, Pd, Rh, Ru, Os, or Ir and treating the impregnated material with a solution of an alkali metal or alakline earth metal borohydride to deposit the platinum group metal.  Alternatively the support can be impregnated with the borohydride solution and treated with the solution of the required metal salt.

Patent HK-46180-A (HK)
Title: Electronic timepiece
IPC: G04G3/02
Filed: 1980-08-28
Abstract: The electronic timepiece comprises an oscillator circuit for generating a high-frequency basic signal, as well as a multistage frequency divider circuit (F1 - Fk+n), at least one of the divider circuit stages serving the purpose of generating a time signal derived from the basic signal. In this case, a phase-shifting circuit (6) is provided which is connected in series with the stages of the divider circuit (F1 - Fk+n) between two stages (F2 - Fj). Furthermore, a phase control selection circuit (7) is provided which is connected to at least one of the divider circuit stages which is connected downstream of the stage (Fj) downstream of the phase-shifting circuit (6) for the purpose of generating a control frequency signal in order to feed a phase control signal to the phase-shifting circuit (6). In this case, the phase-shifting circuit (6) can be operated optionally both as an advancing circuit and as a time-delay circuit in such a way that a frequency signal which is advanced or delayed in phase by at least 180 DEG  appears at the driven divider circuit stage in each period of the phase control signal of the phase control selection circuit (7). This permits regulation of the timepiece within a large range of deviations of the fundamental frequency of the quartz crystal vibrator. <IMAGE>
