Title: Improvements relating to aircraft gas turbine power plant installations
Inventor: MURRAY FREDERICK REGINALD
IPC: F02C7/04
Filed: 1951-01-19
Abstract: 714,157. Gas turbine plant. ROLLS-ROYCE, Ltd. April 18, 1952 [Jan. 19, 1951], No. 1548/51. Class 110(3) [Also in Group XXXIII] In an aircraft gas turbine plant having an axialflow compressor, the air intake passage has a wall in which is formed a circumferentially extending slot through which air can be introduced to increase the kinetic energy of the boundary layer of the air flowing through the passage. This prevents unstable running due to the non-uniformity of air flow into the axial-flow compressor 10 which tends to occur when the aircraft is stationary or flying at low speed. Under these conditions, the pressure in the air intake passage 12 is below atmospheric, the pressure difference opening flap valves 20, which may be spring-loaded, to admit additional air to an annular chamber 17, from which it enters the passage 12 by way of an annular slot 16. Preferably, slot 16 extends substantially wholly around the wall of passage 12, a portion 18 of the wall being turned ouwardly. as shown, to form the slot. Swirl imparting devices, which may be adjustable, may be included in the slot 16 and may be additional to, and upstream of the guide vanes, adjustable or otherwise, which are normally provided at the compressor intake. An air intake slot may be formed in the inner fairing 14. to which the auxiliary air is conveyed from chamber 17 through hollow struts 23. To prevent surging or instability in the compressor at low engine speeds, air may be bled from an intermediate stage or stages of the compressor through bleed valves 21 and conveyed, as through a duct 22. to the chamber 17 and thence into the passage 12 The air bleed may be continued throughout the full range of engine speeds so long as the aircraft is stationary or flying at low speed. Hot air for de-icing may be introduced into the passage 12 through chamber 17 and slot 16 and also through additional inlets which ensure that the hot air mixes well with the main body of air in the passage 12. Specifications 579,657. [Group XXXIII], and 587,126 are referred to.

Title: Recovery of phthalic anhydride
Inventor: BETTS WESLEY DONALD
IPC: C07C51/573
Filed: 1959-01-20
Abstract: Phthalic anhydride in solid form is recovered from hot gases containing phthalic anhydride vapour by introducing water droplets into the hot gases in a cyclone separator by the injection of water through a spray nozzle in the inlet of the cyclone separator, cooling the gases directly by the evaporation of water droplets thus precipitating phthalic anhydride direct which is separated from the cooled gases by the cyclone separator.  To minimise the amount of water required the hot reaction gases from the phthalic anhydride manufacturing unit may be precooled by indirect contact to not below 135 DEG C., if subsequently the amount of water injected does not largely exceed the amount needed to effect condensation then saturation will be avoided and hydrolysis will not follow to any substantial extent.  The coprecipitation of maleic anhydride may be avoided if the temperature of the cooled gas is kept above 80 DEG C.
