Abstract: 530,677. Projectiles; sound-reproducers. JACKSON, L. MELLERSH-. (Commercial Ingredients Corporation). Dec. 13, 1938, No. 36342. [Class 9 (i)] [Also in Group XXXVIII] A projectile is provided with means for generating gas or with a reservoir of gas, means for causing  generation or release of said gas at a predetermined time or upon impact of the projectile, and for expelling it at a high velocity through ports in the projectile casing, and means for varying the velocity cf the escaping gas to cause it to emit sound of a desired character. In the form shown in Fig. 1, a shell has a filling of a powder 5 adapted to be fired at the point 6 by a flame projected along a tube 7 from an explosive  material 8 when struck by a firing pin 9. On impact with the ground, the fuze 3 is forced into the end of an outer casing 12 which is thereby splayed out to prevent undue penetration of the projectile into the earth. As the powder burns, the combustion products pass out through passages 25 to operate a siren comprising stationary blades 26 and movable blades 28 forming part of a rotor 27. The powder is packed in sections having different rates of burning and may produce noxious or toxic gases to prevent approach to the projectile while the siren is operating. In a modification the projectile is adapted to be released from an aircraft and is provided with stabilizing blades and with a parachute to slow up the projectile before impact with the ground. Fig. 4 shows a form of aerial bomb provided with a parachute. The withdrawal of a pin 64 allows the release of the parachute and opens a valve 66 through which compressed air from a chamber A passes into a Venturi 53, past a controllable gate 54 and out through orifices 55. The gate is controlled by a stylus 56 resting on a serrated band 58 operated by a motor 59 which is switched on when the pin 64 is withdrawn. The gate comprises a plate with slits vibrated into and out of register with corresponding slits in a plate 63 to produce articulate sounds according to the form of the serrations on the band.

Class 82(1) Magnesium oxide materials are reduced electro-thermally with a metallic reducing agent which does not yield any volatile reaction products other than magnesium, the reducing agent being mixed with the oxide in finely divided state and in such a surplus over that theoretically required that the conductivity of the mixture for the passage of electric current induced in or led to the reaction mixture by means of electrodes is maintained at almost metallic conductivity i.e. corresponding to a resistance of a centimetre cube equal to 1-6 milliohms until the reaction is completed. The magnesium oxide material, ground to 5-150 microns, and reducing agent such as ferrosilicon, ground to 5-50 microns, are mixed, the excess of silicon being preferably such as to result in the formation of alloys or compounds with the accompanying metal, .e.g. iron, which have a low reactivity to magnesium oxide. The reaction residue may be recovered in a solid condition or it may be removed after melting, surplus reducing agent being recovered by wet-mill treatment or in liquid form for re-use. In the apparatus shown in the Figure reaction materials are introduced from vessels 1 and 3 to reaction space 5 in which they are heated by current passing between electrodes 6 and ring electrode 7. The reaction residue is removed from the apparatus past revolving grate 11. Magnesium is condensed in a condenser 8 in liquid form and runs into a barometric column 18 of liquid magnesium from the bottom of which it is withdrawn. Two further condensers 19 and 20 are mounted in parallel, each in turn serving to condense any remaining magnesium vapour to the solid form at a temperature of 20-500‹C. while the temperature of the other is raised to 650-700‹C. to melt and run off any magnesium condensed therein. Baffles are preferably provided within or before the main condenser to assist condensation and the ratio of condensation area to amount of magnesium condensed in unit time should not exceed 20 sq. metres per ton of magnesium per hour.
