IPC: F01D1/30
Filed: 1950-06-13
Abstract: 696,817. Gas turbines. ROLLS-ROYCE, Ltd. Sept. 11, 1951 [June 13, 1950], No. 14805/50. Class 110(iii) In a reversible inward radial flow power turbine of a gas turbine power plant, a set of nozzles or guide vanes 16 is radially spaced from the periphery of the rotor 10, and a second set of nozzles or guide vanes 17 is adapted to be disposed between the first set of guide vanes and the rotor whereby the turbine is rotated in the reverse direction. The nozzles 17 shown in full lines in Fig. 2 in the inoperative position, are disposed in an annular chamber 21 and may be moved parallel to the rotor axis to the operative position as shown in chain-dotted lines. The nozzles 17 have shrouds 19 which together form a ring which in the inoperative position engages recesses 20 so as to present a smooth contour to the working fluid annular inlet passage 14. The shroud ring 19 may engage a similar recess in the opposite wall of the inlet passage when in the operative position. The nozzles 17 have shouldered roots 22 which engage radially-disposed slots in the ring 23 which is mounted in a recess in the ring 25. The nozzles are moved by means of an operating ring 27 having a recess 28 in which is disposed a block 29 which engages a pin 30 on the radius arm 31. This arm is secured on a shaft 32 rotatably mounted in the turbine casing 13, the shaft carrying a second radius arm 34 at its other end which is connected by a pin 35 to the nozzle carrier ring 25. Upon movement of the operating ring 27, the nozzles 17 are therefore moved with axial and circumferential components into the operative or inoperative positions. Alternatively, the nozzles 17 may be mounted on guide blocks, which may be circular, which slide in correspondingly-shaped bores in one wall of the inlet passage 14, or the nozzles may be unshrouded and slidable in bores of the same shape as the nozzle profile. The invention may be applied in the case of a marine gas turbine plant, the gases from the power turbine upon discharge passing to an axial flow turbine driving a compressor; alternatively, the compressor-driven turbine may be located upstream of the power turbine. Specification 630,164 is referred to.

Title: Improvements in and relating to the manufacture of crystalline materials
IPC: B01D9/00
Filed: 1929-05-13
Abstract: 325,757. Dering, H. O. May 13, 1929. Crystallizing.-Salts normally producing relatively unstable super saturated solutions are obtained in rapidly soluble crystalline form by first forming a supersaturated solution of the salt in question in a vessel having a substantially smooth and continuous inner surface by cooling a hot concentration solution in a quiescent state, while preventing evaporation at the surface thereof, and then causing the solution to crystallize by agitation or by seeding. Practically the whole of the solution forms an interlacing crystalline mass without formation of solid sides or bottoms. The convection currents formed during cooling are checked by cooling the solution very slowly and evaporation is prevented at the surface of the liquid by covering it with a layer of water or other liquid or by fitting the vessel with a tight lid. The water may be introduced without disturbing the solution by running it on to the surface of a thin, board floating on the solution. Examples of the crystallization of magnesium sulphate, sodium carbonate, sodium sulphate and sodium thiosulphate are given.

Abstract: 572,423. Purifying gases. SAVARY, J. Sept. 13, 1943, No. 14975. Convention date, Oct. 10, 1942. [Class 1 (i)] The gum forming constituents in a hydrocarbon gas are removed by contact with liquid hydrocarbons. In an example the hydrocarbon gas is passed into a purifier 2 which may be filled with a porous or semi-activated substance 8, wherein the hydro-: carbon vapours and gum forming constituents are condensed. When the purifier 2 is saturated with condensed hydrocarbons, the vapours pass into an adsorber 5 containing an adsorbent 9, but the gum forming constituents are retained by the condensed hydrocarbons in the purifier, the clean gas passing to the point of use through pipe 7. The adsorbent 9 may be cleaned of adsorbed hydrocarbons by passing steam or hot gas through the pipes 10 and 12 after closing valves 4 and 6. When substance 8 is saturated with gum forming constituents it is removed and replaced by fresh material. If several adsorbers are employed one may be used as a purifier in which case it is not cleaned until the adsorbent is saturated with gum forming constituents.
