Title: Flow discharge device, eg gas turbine engine compressor bleed outlet
Inventor: HUSSAIN ZAHID MUHAMMED
IPC: B05B1/02
Filed: 2009-03-17
Abstract: A flow discharge device, such as a compressor bleed outlet discharging into a bypass duct (22, fig.1) of a gas turbine engine, comprises an outlet panel 46 having at least one opening which tapers in the downstream direction with respect to the flow B in the bypass duct. The outlet may have a single opening or may be perforated by a number of openings 48, 50 disposed in an array. The configuration of the array of openings 48, 50 creates a plume 60 of tapering form, which enables the bypass flow B to come together downstream of the plume 60 with minimal wake generation, to provide a shield of cooler air so as to avoid contact between the hot gas plume 60 and a wall of (27,fig.1) of the bypass duct 22. The resulting aerofoil-shaped cross section of the plume 60 also reduces any blocking effect in the bypass duct (22), with consequent performance benefits for the engine fan (13, fig. 1).

Abstract: 566,592. Underfeed furnaces. BIGWOOD. & SON, Ltd., J., TINLEY, E. L., and DRIVER, F. A. June 25, 1943, No. 10255. [Class 51 (i)] In an underfeed furnace in which the ashpit contains water, fuel is fed by a screw or ram to a trough 13 from which it passes to a raised central portion 11 of the grate surrounded by tuyeres 16 and thence to a surrounding portion 18 at a lower level. A fan supplies air for combustion to a U-shape conduit 32 from which it passes through openings 35 over the water in the ashpit 21 where it picks up water vapour and passes through openings in the grate portion 18 and to the tuyeres 16. Part of the air and water vapour serves to cool the grate and becomes preheated and thereafter passes into the U-shape conduit 33 and returns to the fan for recirculation. The U-shape air conduits 32, 33 serve to support the outer portions of the grate. The water level in the ashpit is maintained by flow and return pipes and ashes are removed through a shaft 24 provided with a door 25. In a modification (not shown), air is supplied by the fan to the ashpit through a pair of air supply conduits and part is returned from the ashpit to the fan through another pair of conduits. The return pipes may communicate with the atmosphere.

Title: Improvements in or relating to coating machines and methods of cooling workpiece supports thereof
IPC: B05D1/32
Filed: 1964-03-11
Abstract: In the deposition of thermosetting resin coating material on a workpiece which is heated to cause fusion of the applied material, the workpiece is mounted on a hollow mandrel or support member the surface of which is, at least in part, perforated and air or other cooling gas is supplied to the perforations by means of a hollow shaft to which the support member is attached, the support member and possibly also certain parts of the workpiece are by this means maintained at a temperature such that adherence of the coating material thereto is prevented.  The invention is described in connection with the spraying or blowing of thermosetting resin powder on to the end portions of a stator core supported by contact of its pole pieces with a perforated mandrel.  The polepieces are arranged to cover the perforations in the mandrel. Air is supplied under slight pressure to the mandrel and in escaping through the perforations cools the mandrel and parts of the stator core.  In one embodiment (Fig. 5, not shown) the perforated mandrel is of a porous sintered metal construction.
