Abstract: Stabilized coal-oil mixtures are obtained by mixing pulverised coal particles with oil and a surface treating mixture comprising an organic monomer and a free radical catalyst and initiator, heating the mixture so formed first under conditions of low shear and then under high shear, and finally adding a gelling agent to the mixture to form the mixture into a thixotropic gel or paste. Preferably the coal particles are initially washed and rendered hydrophobic and oleophilic by an initial treatment in an aqueous medium comprising organic monomer, a polymerisation catalyst and initiator and an organic liquid carrier.

Abstract: An improved wholly aromatic polyester is provided which exhibits an anisotropic melt phase and which is capable of readily undergoing melt processing. The wholly aromatic polyester consists essentially of the recurring units (a) p-oxybenzoyl moiety, (b) 2,6-dioxynaphthalene moiety, (c) 2,6-dioxyanthraquinone moiety and (d) terephthaloyl moiety in the concentrations indicated. The resulting polymer is substantially free of aromatic rings possessing ring substitution and meta disposed linkages in the polymer chain. The present invention represents an improvement over the polyester of U.S. Patent No. 4,184,996 since the melt phase may be formed at an advantageously reduced temperature, thereby better facilitating the use of standard melt processing equipment when forming fibres, films, three-dimensional shaped articles, etc. The reduction in possible melt processing temperature is accomplished without any significant diminution in melt anisotropy such as that which would result if non-symmetrical meta disposed linkages were present in the polymer chain. Also, the present polyester does not rely upon the presence of ring substitution as a means for producing the desired melt anisotropy.

Abstract: Apparatus for continuously producing continuous oxidized filaments (1) includes a series of lower guide rollers (4a, 4b, 4c ...) provided at the outside of a furnace (2) for guiding the filaments and a series of gas suction seal chambers (8a, 8b, 8c ...) provided inside the bottom of the furnace. The gas suction seal chambers have a series of sub-partition plates (23a, 23b, 23c ...) which are arranged along the path of filaments and have gas passing means. The external air which tends to go into the furnace through the slits (10) formed in the bottom wall (20) of the furnace will be sucked into the gas suction seal chambers and prevented from entering the heated oxidizing atmosphere in the furnace. Thus the temperature variation in the furnace will be reduced and the quality of produced filaments will be improved. The upper guide rollers (3a, 3b, 3c ...) may be outside or inside the furnace (2). If they are outside the furnace (2), a series of gas supply seal chambers (5a, 5b, 5c...) inside the top of the furnace (2) performs an analogous function to the gas suction seal chambers (8a, 8b, 8c ...) at the bottom.
