Axial-flow and combined-flow types; blades, regulating.-In a water turbine, radial or inclined blades F for axial or axial-radial flow are carried by the rotor and preferably are not provided with a rotor rim. The blades are spaced apart so that at their tips they have " wing " characteristics and near their roots " cell " characteristics as defined in Specification 17588/14. In the form shown, the water enters the casing radially between guide-blades S and turns into an axial direction partly in the guide-blade spaces and partly in the free space x. The guide blades may or may not overhang the suction tube. The blades may be inclined downwardly from the hub for radial inlet or upwardly for an axial inlet. The blades may be cast into the hub, cast integrally with it, or be flanged and secured by bolts. The flanges may have concentric slots so that the angularity of the blades may be adjusted. The Specification as open to inspection under Sect. 91 (3) (a) also states that the diameter d of the hub should not be greater than ten times the diameter d<1> of the shaft, and that the adjustable blades mav be secured and adjusted by means of wedges.

Abstract: 1,171,386. Forming polyimide articles. MINNESOTA MINING & MFG. CO. 11 Jan., 1967 [12 Jan., 1966], No. 1466/67. Heading B5A. [Also in Division C3] Articles are formed from polyimides by forming a dilute solution of a polyamide acid, subjecting the solution to shearing forces while heating it to a temperature below the heat curing temperature to remove solvent, shaping the substance formed and heating to drive off the remainder of the solvent and convert to a polyimide. Preferably the solution initially contains about 15 wt. per cent polyamide acid, is heated first to 90-120‹ C. and then to 65- 150‹ C. in a rubber mill to give about 75% polyamide acid and is then moulded and heated to a temperature above 150‹ C. A sheet of polyimide of thickness greater than 10 mils may be prepared by the above process in the apparatus shown, the polyamide acid solution being run on to conveyer 12 for the initial heating, through mill 14 to exert the shearing stresses and on to conveyer 18 where it is heated at 20 to convert the sheet to polyimide and drive off excess solvent. The example specifies preparations of a polyimide from the polyamide acid of 4,4<SP>1</SP>-diaminodiphenyl ether and 3,4,3<SP>1</SP>,4<SP>1</SP>-benzophenone tetracarboxylic anhydride in dimethyl acetamide and also from 4,4<SP>1</SP>-diaminodiphenyl ether and pyromellitic-dianhydride.

Abstract: 126,677. Rudge - Whitworth, Ltd., Fugh, J. V., and Pountney, F. Feb. 7, 1917. Projectile fuses.-Relates to percussion fuses having a centrifugal bolt normally held in locking engagement with the inertia pellet by a resilient member, and consists in an arrangement whereby the force exerted by the resilient member increases during the flight of the projectile as the bolt moves radially outwards, up to a point at which the said member no longer acts upon the bolt. In the fuse shown in Figs. 1 and 2, the centrifugal bolt g is held in the locking position. as shown, by a springy split ring l which is located in a groove k. This is cut deeply at k<1>, Fig. 2, in such a way that as the bolt moves outwards under centrifugal action, the opposition of the spring l to this movement increases, owing to the forcing apart of the ends of the spring by the surfaces k', until the points k<2> are passed, whereupon the resistance ends and the bolt g and ring l leave the fuse-body. In a modification, an endless coiled spring takes the place of the split ring l. Specification 126,387 is referred to.
