The vanes 19 and the shrouds 11, 18 are provided with porous surfaces for the passage of coolant air derived from the compressor (not shown) and supplied to the combustion chamber jacket 83 within the combustion casing 5. The air for cooling the vanes 19 and shroud 11 is taken from a plenum 82 connected through holes 85 to the jacket 83 and the air for cooling the shroud 18 is taken from a plenum 90 connected through holes 91 to the jacket. Vane construction. Each vane 19 Figs. 3, 4, 5 comprises a hollow airfoil portion 34 formed of porous laminated metal sheet and closed at the ends by a base 41 and plug 43, the base and plug also serving to secure the vane to the shrouds 11, 18. The base 41 has an opening 45 for the entry of coolant air and the concave and convex faces 38, 39 of the hollow portion 34 are separated from each other by an internal baffle 46. Opposite the leading edge 35 of the vane the baffle 46 has slots 65 whereby air is jetted through the slots to cool the leading edge by impingement thereon, this air leaving the vane by passing through the pores provided in the convex face 39. Other coolant air leaves the vane by passing through the pores in the concave face 38, this air being at a higher pressure since it has not passed through the slots 65. The airfoil portion 34 is a laminated assembly Fig. 8, consisting of an outer layer 55 intermediate layer 56 and inner layer 57, the pores 60, 54 in the inner and outer layers, respectively, being in registration but the pores 62 in the intermediate layer being out of registration so that the coolant has to follow tortuous paths formed between bosses 61, 63 provided in the layers 57, 56 to space apart the three layers. The convex face 39 has twice the number of pores provided in the concave face 38 and the leading edge 35 is not provided with pores Fig. 7. Shroud construction. The outer shroud 11 has ridges 77 covered by a sheet 78 of porous material forming annular chambers 79, the chambers receiving coolant through radial passages 81. The inner shroud 18 has, a porous sheet 86 mounted on ridges 87 forming annular chambers receiving coolant through passages 89. Since the hot motive fluid-pressure decreases in the downstream direction through the turbine and it is desired to control the flow of coolant to obtain the required temperature along the porous sheets without wastage of the coolant, the pores in the sheets 78, 86 are so designed and the passages 81, 89 are so proportioned that the coolant is supplied to different portions of the sheets at different pressures corresponding to the different pressures of the motive fluid exerted against the different sheet portions.

Abstract: 667,664. Drafting textile fibres. PACIFIC MILLS. April 18, 1947 [May 9, 1946], No. 10440/47. Classes 120(i) and 120(ii) Slivers, rovings or the like are given very high drafts in. a single stage by producing frictional restraint between fibres by compressing them to predetermined degrees by means including moving surfaces located at a plurality of stations between feed and drafting rollers, the degrees of compression being proportional to the weight per unit length of sliver as it passes between the moving surfaces. Two or more pairs of feed and drafting rollers, such as A, C, E, may be used and all but the last pair may be adjustable upon their bed M, so that alteration of the ratch according to the length of fibres may be made. Feed rollers A1, A2 are located between side walls A5, A7 (A7 not shown) and the upper roller A1 is spring-pressed towards the lower roller, but is held a minimum distance from it determined by the thickness of a shim All, which may be changed to accommodate slivers of various weights per unit length. Between the roller pairs, slivers are controlled by sets of pressure rollers B, D, operating within laterally adjustable, side walls. Each set of upper pressure rollers is journalled in a block pivoted on the shaft of the first bottom pressure roller, such as B3. The block is held a predetermined distance away from the first bottom pressure roller by an exchangeable shim, such as B15, and the second and third pairs of rollers are held a minimum distance apart by a stop, such as B23, adjustable spring-pressure being applied to urge the top rollers to the predetermined positions. Facilities are provided for readily changing the gearwheels transmitting drive to the drafting and pressure rollers and gears B10 and D2 are journalled in yokes, such as B31, which are vertically and horizontally adjustable to maintain the drive after changes in the ratch. Examples are given of the relationships of areas of typical nip openings to the weight per unit length of slivers. When passing from feed to drafting rollers, the sliver preferably is compressed to a crosssectional area in the range between 1-14 times G10-<SP>5</SP> and .428G10-<SP>5</SP> (where G represerits the weight in grains per forty yards of sliver at the feed roller nip) and then further compressed to a cross-sectional area in the range between 10 times G10-<SP>5</SP> and 2.14 times G10-<SP>5</SP> (where G represents the weight in grains per forty yards of sliver delivered by the drafting rollers). Examples of the drafts mentioned are 173 for wool fibres and 423 for viscose rayon fibres.

Abstract: A chain of substantially identical serial neighborhood transformation are utilized to sequentially access all of modules 10 is utilized to analyze a pattern represented by a serial stream of digital electrical signals representing a matrix of points. Each module includes a series of shift registers which are utilized to sequentially access all of the neighborhoods in the matrix. A control portion in each module 10 analyzes each neighborhood by comparing it to a stored pattern, which may be altered by a controller 20, and provides the transformed output to the succeeding module. The length of a curve may be analyzed, the signal representing each end point of the curve being transformed into a unique code, the signal representing each point on the curve adjacent a point now represented by the unique code being itself transformed into the unique code. This latter step is carried out L DIVIDED 2- 1 times and then each unique code representing a point on the curve adjacent a non- transformed point is transformed into its original code, this being carried out L DIVIDED 2 times. A curve of length greater than L will then be represented by original codes and a curve of length L or less will be represented by the unique codes. <IMAGE>
