Title: Manufacture of alcohols
IPC: C07C29/04
Filed: 1932-06-25
Abstract: Alcohols are produced continuously in treating a mixture of propylene or its higher homologues and steam with a dilute inorganic acid such as sulphuric or phosphoric acid at high pressure, the acid being maintained at uniform strength and temperature, and cooling the vapours to condense the alcohol.  The acid may be of 15--60 per cent strength, the pressure may be 200--600 lb. or higher and the temperature 200--250 DEG  C. or higher.  The steam may be used in excess, but smaller quantities may be used, especially when the production of ethers as well as alcohols is desired, one part of steam to three of propylene being mentioned for this purpose. Filling-materials may be placed in the acid to effect intimate contact, or the acid may be absorbed in carriers such as pumice or silica gel.  Small quantities of lithium salts may be added as promoters.  In examples, propylene acid steam are treated with sulphuric acid of 27 and 35 per cent strength at pressures of 250 and 125 lb. and temperatures of 200 DEG  and 171 DEG  C. respectively. Specification 368,935 is referred to.  The Specification as open to inspection under Sect. 91 includes examples in which (1) equal parts of propylene and steam are passed through 58 per cent sulphuric acid at 130 DEG  C. and atmospheric pressure; (2) a mixture of propylene and steam is passed into 3,5--5 per cent sulphuric acid at 210--225 DEG  C. and 1000 lb. pressure, 10--13 per cent of the propylene being converted into isopropyl alcohol and 3--4 per cent into isopropyl ether; (3) a mixture of one part of steam to three parts of a gas containing 64 per cent propylene and 36 per cent propane is treated with 4 per cent sulphuric acid at 190--200 DEG  C. and 1000 lb. pressure, about 10--11 per cent of the propylene being converted into isopropyl alcohol and 5 per cent to isopropyl ether.

Title: Improvements in rotary bladed compressors and turbines
Inventor: SEYMOUR DONALD GLENFIELD
IPC: F02K3/02
Filed: 1961-01-06
Abstract: 992,941. Gas turbine plant; axial flow compressors. BRISTOL SIDDELEY ENGINES Ltd. Jan. 4, 1962 [Jan. 6. 1961], No. 668/61. Headings F1C, F1G and FIT. A turbine or compressor comprising a stator and rotor wherein a flow passage partly defined by a non-coaxial surface capable of causing a circumferential variation of flow of working fluid through a ring of rotor blades tending to cause dangerous vibration of the blades, has the blades of at least one ring of stator blades positioned sufficiently near the ring of rotor blades to modify the flow of fluid therethrough and arranged to have a compensating variation of shape, angle of attack or spacing such as to reduce or eliminate the vibration. Hollow radial struts 40, Fig. 2, supporting a rear bearing in an axial flow compressor of a gas turbine engine cause a flow disturbance to extend upstream through the stator and rotor blades S6 and R6 respectively. The disturbance is attenuated by setting the stator blades S6 so that the flow passages diverge adjacent struts 40 but converge at other positions, as shown by dotted lines. This produces a sinusoidal circumferential velocity variation of the same frequency as the disturbance produced by vanes 40 but of opposite phase. Blades S6 may be set by rotating the whole blade or only by modifying the exit angles. In cases where a large turning angle is required an additional upstream stator blade ring may be provided. A table gives estimated changes of stator blade exit angles required to produce a given velocity change. Flow variations can also be induced by varying the circumferential spacing of stator blades in a row, Fig. 4 (not shown). In an application of the invention to a gas turbine, Fig. 5, the exit angles of nozzle guide vanes 51 are modified as shown dotted to compensate for flow disturbances produced by the flame tube walls 52.
