Ammonia and chlorine are prepared from ammonium chloride or an ammonia/hydrogen chloride mixture by heating in contact with a liquid reaction mass comprising a mixture of molten salts in which one or more partially reduced metal oxides in finely divided solid form are held in suspension, collecting the NH3 liberated and oxidizing the mass to liberate chlorine. A preferred embodiment comprises the steps (a) subjecting the metal oxides in the reaction mass to partial reduction by means of a reducing gas, e.g. H2, CO, at 500-550‹ C.; (b) fixing the chlorine of the NH4Cl or NH3/HCl mixture, on the metal oxide particles by contacting the reaction mass and reagents at 300- 420‹ C., thus liberating the NH3 gas; and (c) oxidizing the chlorinated metal compounds with an oxidizing gas and releasing the chlorine using a free oxygen-containing gas. The molten salts are preferably anhydrous alkali metal chlorides. Preferred metal oxides are those of iron, cobalt and nickel. The preferred metal oxide particle size distribution is 20 to 250 microns. An activator, such as a salt or oxide of copper, of manganese or of a rare earth metal may be added to the reaction mass.

Abstract: 673.536. Spray carburetters. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Nov. 8, 1948 [May 7, 1948], No. 28974/48. Class- 7(iii) [Also in Group XII] To mix fuel with an air stream flowing at supersonic speed, either continuous or pulsatory, a shock wave is produced in the air stream in the region of the fuel injection. In the arrangement shown, the fuel is injected into the air stream from a nozzle 2 and mixed therewith by a shock wave O<SP>1</SP> caused by the leading edge of a body 3. The speed of the fuel-air mixture is then accelerated to supersonic in a duct 3 and the mixture ignited by a shock wave O<SP>2</SP> created by the leading edge of a duct 5 as described in Specification 673,629, [Group- XII]. In another arrangement the shock wave 0<SP>1</SP> is caused by having the main air stream struck by an upstream jet of an air and fuel mixture too rich in fuel and therefore uninflammable. The air flow in the region of the shock-wave 0<SP>1</SP> may be controlled by a throttle disposed in the duct 1 r by making the members 1 and 3 axially movable with respect to one another.

Filed: 1973-06-19
Abstract: 1428744 Supports for waveguides POST OFFICE 7 June 1974 [19 June 1973] 29005/73 Heading H1W A waveguide is substantially supported by the buoyancy of a fluid in which it is wholly or partly immersed. The waveguide may form part of a system for long-distance transmission using TE 01  circular-electric wave propagation. The fluid preferably has a low vapour pressure. For glass fibre waveguides high vacuum oil may be used, and for steel waveguides, glycerine. In order to obtain the correct density, two immiscible fluids may be used. If the density of the waveguide is high, it may be surrpunded by a jacket of low-density material, e.g. a cellular material. As shown in Fig. 1, the waveguide 1 is confined in an underground duct 2 filled with fluid 4 for which one or more expansion chambers 6 are provided. If the waveguide has relatively heavy joints 3, the fluid may have a density equal to the mean density of the waveguide between the joints, in which case the joints tend to rest lightly on the bottom of the duct. However, the joints may be of the spigot and socket type using no additional material (Fig. 4, not shown) and the fluid may then have a density equal to the mean density of the whole waveguide. Fig. 3 shows a method of inserting the waveguide 1 into a duct 2 using fluid pressure. The end of the waveguide is provided with an annular seal 12 whereby it forms a piston so that the waveguide is drawn into the duct through a gland 16 as fluid is pumped into the duct from a reservoir 10.

Abstract: In the manufacture of water-resistant abradants, e.g. emery paper and whetstones, a resinous condensation product formed by the reaction of a polyhydric alcohol and a mixture of a fatty acid having at least 10 carbon atoms in the molecule with an organic polybasic acid or with a synthetic resin carboxylic acid, is used as the adhesive or binder. Examples of polyhydric alcohols are glycol, glycerine, pentaerythrite and mannite.  As polybasic organic acids there may be used, phthalic, maleic, malonic, succinic, and ether-diglycollic acids, and as fatty acids, capric, lauric, palmitic, stearic, oleic, and ricinoleic acids.  Synthetic resin carboxylic acids are obtainable by causing a halogen fatty acid, particularly a chloracetic acid, to react with a phenol-aldehyde resin in the fusible state.  In examples (1) glycerine mixed ester from linseed oil and phthalic acid is diluted with twice its weight of acetone and applied to a strip of paper; silicon carbide grains are applied and rolled in; the resin is hardened by heating for 4 hours at 100 DEG  C. and one hour at 130 DEG  C.; (2) glycerine mixed ester from linseed oil and phthalic acid diluted with acetone is mixed with finely divided silicon to form a suspension; a band of asbestos is impregnated with this suspension, dried and hardened: the treated band can be used for abrading purposes and as a brake band.  Other examples are given. Specification 284,349, [Class 95, Paints &c.], and U.S.A. Specification 1,667,189 are referred to.

Abstract: 911,665. Belt, rope and chain gearing. TEWES, O. Dec. 11, 1958, No. 29103/58. Class 80 (1). In a tensioning device for a belt, rope or chain drive in which the driving means is so mounted that its reaction torque causes it to move eccentrically, or slide, to effect a tensioning of the drive in accordance with the load, the weight of the driving means is balanced and further means are provided to effect a pretensioning force which when the drive is running acts in the same direction as the reaction torque for either direction of rotation. In Fig. 1, a driving pulley 1 is arranged to move around the shaft 2 of a motor, to which it is geared by gearing 2a, by torque reaction to tension the driving belt. The pulley and gearing is carried on a pivoted arm and is balanced by a counter-weight 4 thereon. A pretensioning weight 5 is arranged directly over the centre of motor shaft 2 so that it moves over-centre one way or the other according to the direction of drive to act in the same direction as the reaction torque. In a modified arrangement, Fig. 2, the motor 1a is arranged vertically so that its weight is automatically compensated for and is carried on a frame pivoting about an axis 2. A weight 5 acting through a cable 8 over a pulley 9 on a lever arm on the motor supporting frame effects the pre-tensioning in the same direction as the reaction torque. In a further arrangement, Fig. 3, the motor is adapted for sliding movement and its weight component balanced by a weight 4 on cable 8. A further weight 5 provides the pre-tensioning of the belt and cables 14 acting on a pulley 13 on the motor frame convert the reaction torque in either direction of rotation to a sliding movement of the motor to effect the torque reaction tensioning.
