A process for the production of coke which process comprises extracting coal at an elevated temperature with a suitable solvent, filtering undissolved material from the extract, concentrating the extract and thereafter coking the concentrated extract while recovering the solvent for re-circulation characterised in that prior to digestion of the coal the solvent is subjected to coking under conditions comparable with the conditions under which the coal solution is subjected to coking until coking...

A solid particulate fuel/air burner has opposing fluted members within a rectangular conduit which in operation forms a nozzle. Splitter plates with the fluted members define passages through which a particulate solid fuel and air flow to a combustion chamber. The passages so defined provide and control separate streams of the mix such that flame retention at the exit of the conduit is achieved and reduced NOx is produced and the gathering of ash in the conduit avoided by the obviation of recirc...

Hollow fibers are differentiated by their void being partially filled with a differentiating characteristic that is a protuberance of characterizing polymer material. This material may be the same or different from that of the rest of the fiber. The protuberance is provided by appropriate adjustment of the spinning capillary, i.e., during extrusion to form the fiber.
