Title: Improvements in or relating to flame tubes
Inventor: ALEXANDER ERIC ARCHIE
IPC: F23R3/06
Filed: 1982-01-15
Abstract: A flame tube (16) for a gas turbine engine has a number air inlets (20) which receive air from the engine compressor for combustion and dilution purposes in the flame tube. In order to stabilise the flow through the air inlets, and in particular to reduce or eliminate any tangential or circumferential velocity component, the inlets each have an airflow control (32) which comprises two fences (34) joined by a bridge piece (36). The fences are mounted on opposite sides of the inlet and prevent or reduce the spillage of air over one or other of the inlet sides. In this way, any tendency for asymmetric flow over the inlet sides is reduced, and the circumferential flow which is detrimental to combustor performance is reduced. <IMAGE>

Title: Manufacture of filamentary polymer tow
Inventor: HILL MICHAEL
IPC: D01D5/098
Filed: 1982-08-03
Abstract: A method and apparatus for the manufacture of filamentary polymer tow by melt spinning in which molten orientable polymer is extruded through a spinnerette plate to produce molten filaments which are cooled to solidify them and draw off at a rate sufficient to cause the required orientation of the filaments, said orientation being the sole orientation step in the process. Usually, (e.g. for use in cigarette filters) the filaments will be crimped after orientation. Thus, the filaments may be drawn off as aforesaid by draw off rollers and fed from the rollers to texturising equipment (preferably a stuffer box crimper) without further orientation, or the filaments may be drawn off as aforesaid directly by the texturising equipment or the filaments may be drawn off as aforesaid through a constant tension device (e.g. dancing arm) and thence into texturising equipment. Directly drawn filaments may be steam treated prior to texturing.
