Title: Improvements in or relating to liquid fuels
IPC: C10L1/18
Filed: 1952-10-01
Abstract: A fuel composition for use in jet aircraft engines comprises a jet fuel comprising hydrocarbons boiling in the range from about 100 DEG F. to 600 DEG  F. and 0.01-1.0 per cent. by weight, based on the jet fuel, of tetra-, penta- or hexa-ethylene glycol.  The presence of the glycol ensures that at low temperatures there is no separation of ice crystals from the composition when the jet fuel contains dissolved or entrained water, and consequently that there is no choking of filters through which the composition passes on its way to the combustion zone of the engine.  Tests are described in which the effect on the filter-plugging tendency of a water-saturated jet fuel caused by the addition of glycols of formula HO(C2H4O(nH, wher n is 1-9, is determined.  The jet fuel employed in these tests is one meeting the JP-4 specification of the U.S.A. military authorities.

Title: Process for the production of bodies of relatively large size from pure silica and other highly refractory oxides
IPC: C03B19/00
Filed: 1951-10-26
Abstract: In a process for the production from pure silica and/or one or more other refractory oxides of large bodies as sections of a continuous length, pure crystalline silica and/or other oxide is fed in granular state to a shaping channel having a cross-section identical with or similar to the cross-section of the bodies to be produced and, by being melted as it travels through the channel, is transformed into a continuous length of plastic material which has, or is subsequently shaped in the channel to have, the cross-section required, and which is divided into sections after leaving the channel.  The source of heat for the melting zone of the shaping channel may be external or internal and may be an electric arc or electric resistance, which latter may be constituted by the walls of the shaping channel. Internal melting is preferably by electrical resistance, and the rate at which the material passes through must be slow enough for it to become liquified or vaporized before it comes into contact with the resistances, so flowing easily past them and then cooling into a coherent body.  The shaping channel is preferably so disposed that the direction of movement through it of the material is vertical and under the action of gravity, the shaped product then emerging vertically or, if the lower end of the shaping channel is suitably curved, horizontally.  The product may be delivered on to rollers. If the material passes through the shaping channel horizontally it is urged forward by e.g. a worm.  When the product after leaving the shaping channel has completely hardened it is cut into lengths while still moving, by devices which move with it.  The relative movement between the shaping channel and the material may be obtained by keeping the material stationary and moving the shaping channel.  To avoid the formation of bubbles the material is preferably preheated to about 1000 DEG  C. which may be done by passing it through a preliminary passage heated by oil, gas or waste heat so designed that the preheating time is at least four times the actual melting time. Alternatively the preheating may be done in a separate furnace.  The outlet of the shaping channel may be fitted with an orifice resembling an extrusion die, through which the material is passed while still plastic.  To give the material sufficient strength as it emerges it is preferably annealed while in the shaping channel by cooling it after passing the heating zone.  The product may be subjected to mechanical treatment such as cutting or grinding, to chemical treatment such as spraying with hydrofluoric acid, or to a glazing process.  The product may be rolled or pressed before or after being cut into lengths.
