Title: Means for controlling the direction of a stream of ionised fluid
IPC: F03H1/00
Filed: 1952-04-04
Abstract: 711,929. Jet propulsion plant. KADOSCH, M., and JURQUET DE LA SALLE, L. DE. April 4, 1952 [April 5, 1951; March 27, 1952], No. 8710/52. Class 110(3) [Also in Groups XXI, XXXIII, XXXVIII and XL(a)] A stream of high temperature gas which has been at least partially ionized, e.g. by thermal action, is deflected by applying an electrostatic or magnetic field transverse to the flow. In the case of jet propelled craft, the deflection may be used for braking or steering. Ionization may be increased by passing the stream through a grid covered with thorium or other radio active salts located upstream of the deflecting field, and negative ions are preferably collected by a positively charged streamlined electrode axially disposed in the gaseous stream so that only positive ions are acted upon by the deflecting field. As shown, Fig 3, applied to a jet propelled rocket, the strongly ionized fluid jet 25 issuing from the combustion chamber 24 is deflected by a radial electric field between a positive central streamlined electrode 27 and a negative concentric ring electrode 26. The deflection causes a portion of the fluid jet to pass through passages 30 and be ejected as at 32 thereby braking the rocket. In another embodiment, for steering the rocket, the central electrode 27 is replaced by a diametral streamlined electrode 27<SP>1</SP>, Fig. 4, and a selector switch 35-36-38, is operated to produce a transverse electric field from this positively charged electrode to one or the other, or both of negative electrodes 26a, 26b symmetrically disposed on opposite sides of the diametral electrode. Closure of both switches simultaneously will effect braking as before, while selective closing of one of them will deflect the rocket in a corresponding direction. In a further embodiment, Fig. 7, the diametral partition is divided into portion s  27<SP>1</SP>, 27<SP>11</SP> which coact respectively with electrode pairs 26a<SP>1</SP>-26b<SP>1</SP>, 26a<SP>11</SP>-26b<SP>11</SP>, thus duplicating the electric field arrangements of Fig. 4. The four fields may be generated singly or in any combination by switches 38<SP>1</SP>, 47, 48. Normally the passages 30 are covered by a conical skirt 52 to avoid objectionable aerodynamic action, the skirt being moved to the position shown dotted when it is desired to generate one or more of the electric fields, e.g. through a lever 57 and cable 56. The various fields may be derived from an A.C. source through a step-up transformer and rectifier. and may be adjusted by potentiometers, all the controls being effected by remote control. Magnetic deflection may be used in lieu of electrostatic.

Title: Improvements in or relating to magnetic separator devices for electron beams
IPC: H01J29/84
Filed: 1959-03-13
Abstract: 854,474. Mass separators, linear particle accelerators. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 13, 1959 [March 13, 1958 ; Jan. 20, 1959], No. 8817/59. Class 39(1). A beta-ray magnetic separator for analysing the output of a linear electron accelerator 1, consists of three sector shaped magnets 5, 6 and 7, Fig. 1, or of four rectangular magnets disposed in two pairs 27, 28 and 29, 30, Fig. 3, so arranged that electrons having relatively lower energies follow longer paths than electrons having higher energies. In Fig. 1 the first sector 5 converts the beam 14 into a divergent beam, the second sector 6 transforms the divergent beam into a convergent beam and the final sector 7 restores the beam to a cylindrical shape. The successive bunches of high and low energies which are produced may then be acted upon by a second linear accelerator 18 so as to produce finally an accelerated beam of monoenergetic electrons. The relation- 'ship between the spacing of the sectors and the radius and angle of a sector are shown in the Figure. Suitable values for α are specified in the description. In Fig. 3, the two pairs of magnets 27, 28 and 29, 30 are symmetrically arranged with respect to the plane 16, the directions of the field in each magnet being indirected at B. The magnets may be adjustable in position or may have adjustable faces. The electron beam need not be cylindrical in shape.

Patent GB-1098361-A (GB)
Title: Improvements in or relating to the production of ammonia and chlorine from ammonium chloride
IPC: C01B7/05
Filed: 1965-03-02
Abstract: A process for preparing ammonia and chlorine from ammonium chloride comprises heating the NH4Cl in contact with a mass containing partially reduced iron or manganese oxide and an alkali metal chloride to liberate NH3 gas, and oxidizing the residual mixture with a free O2-containing gas to liberate Cl2 gas, the contact between the mass and the other reagents being brought about, at least in part, in a fluidized bed. Preferably, the metal oxide in the mass is reduced with a reducing gas to enable the mass to be recycled for further use. The mass may contain solids which are chemically inert under the reaction conditions.  A preferred mass consists mainly of alumina and iron oxide, the amount of Fe2O3 in the total mass being 5-35% by wt. Alternatively, the mass may be prepared from an iron-based ore in which the iron is at least partly in the form of an oxide, hydroxide or carbonate in an amount as Fe2O3 of between 15 and 75% by wt. KCl is the preferred alkali metal chloride, present in an amount such that the mole ratio of KCl/Fe2O3 is from 0.2 to 2.5.  Optional activation promoters such as salts of copper, zinc or the rare earth metals may be present in the mass which preferably consists of particles of 20 m  to 1 mm.  The reaction of the fluidized mass and the NH4Cl may take place at 350-500 DEG  C. and the oxidization of the residual mass at 450-650 DEG  C.  The regeneration by reduction may be effected at 400-700 DEG  C.  Apparatus for carrying out the process is described and illustrated comprising a reaction vessel containing a charge of the mass maintained in a fluidized condition within the vessel, said vessel having at or near its base a pipe for the admission of NH4Cl and a pipe for the admission of the reaction gases and having at the top a pipe for the extraction of the gases leaving the fluidized bed.  A group of at least 3 of such reactors may be arranged in series.
