Title: Fluid flow machine such as a gas turbine engine
Inventor: BRACEY KENNETH EDWARD GEORGE
IPC: F01D17/16
Filed: 1961-05-23
Abstract: 946,995. Turbines. ROLLS-ROYCE Ltd. May 16, 1962 [May 23, 1961], No. 18654/61. Heading F1T. A fluid flow machine has a ring of blades each of which, at its root and at its tip, has a platform which is mounted in a casing for pivotal movement between two extreme angular positions, each platform being of a shape such that in each of the extreme angular positions the platforms of adjacent blades contact each other to prevent fluid from passing between adjacent platforms and thus around the blades, means being provided for effecting pivotal movement of the blades. A gas turbine engine has nozzle guide vanes 15 having platforms 17, 18 with flats 20, 21 of which the flat 20 is of greater length than the flat 21 and is disposed alongside a flat 21 of an adjacent nozzle guide vane 15. The platforms 17, 18 are pivoted in casings 26, 27, sealing of the curved portions 22, 23 being effected by labyrinths 24, 25. Leakage across the vanes 15 is prevented by contact between either the upstream or downstream ends of adjacent flats 20, 21. The casing 27 is spaced from the engine casing 10 by an annular space 30 supplied with compressed air. Pivotal movement of the vanes 15 is effected by a fixed piston 32, forming part of the casing 27, and an axially movable cylinder 33 having an axial annular extension 34. Movement of cylinder 33 is controlled by a two-way valve 40 connected to compartments 35, 36 in cylinder 33, to compressed air in space 30 and to atmosphere. Annular extension 34 has fingers each of which is pivoted to an arm attached to a hollow quill shaft 43 welded to platform 18 of vane 15. In a modification movement of the vanes 15 is effected by pneumatic rams 50, Fig. 6, each having a piston 51 pivoted to an axially extending lever 53 whose downstream end is pivoted to a fixed structure at 54. A ring 55, rotatable circumferentially of the engine has parts 56 through which the levers 53 pass. Blocks 57 on ring 55 are connected by arms 60 to vanes 15. Thus movement of pistons 51 and levers 53 causes rotation of vanes 15. In both embodiments the vanes 15 are cooled by air fed from space 30 through the quill shafts.

Title: Improvements in or relating to step-by-step electric switch mechanisms
IPC: H01H3/26
Filed: 1947-07-15
Abstract: 627,165. Snap-action switches; regulating switches. STANDARD TELEPHONES & CABLES, Ltd., MOODY, N. F., and SHARPE, .C. J. July 15, .1947, No. 18816. [Class 38(v)] [Also in Group XXXVIII] In a motor-driven switch mechanism intended primarily for use in an automatic impedance bridge (see Group XXXVIII), a continuous rotation is converted to a stepby-step movement to actuate a switch contact arm. The main shaft 5 of the mechanism is driven by a reversible motor (not shown) and carries a pinion 6 driving a crown wheel 7 which is free to rotate on the shaft 8 which carries the contact arm (not shown). A pin 12 fixed to the crown wheel 7 engages an arcuate slot 13 in a collar 14 having a pin 15 engaging a slot 16 in a plate 17, both the collar and plate being free to rotate on the shaft 8. The plate 17 also carries a pin 18 which moves in a slot 19 in a " click " plate 20 fixed to the shaft 8, and springs 21, 22 are connected between the pin 18 and pins 23, 24 fixed to the plate 20. The plate 20 has a number of holes or depressions 25 which co-operate with a spring-pressed ball 26. When the shaft 5 is driven, the crown wheel 7 moves the pin 12 to the end of the slot 13. The collar 14 then rotates and moves pin 15 to the end of the slot 16, and the plate 17 is now driven. The pin 18 now tensions either spring 21 or 22 depending on the direction of rotation, and on reaching one end of the slot 19 commences to move the plate 20. This disengages the ball 26 and the tensioned spring moves the plate 20 and shaft 8 rapidly to the next switch position, where the ball 26 engages the next hole 25. This movement restores the pin 18 to the centre of the slot 19 ready for the next step if the motor continues to run. The lost-motion connection provided between the motor and plate 17 by the pins 12, 15 and slots 13, 16 permits the use of the same motor to drive a potentiometer before the first movement of the switch arm occurs. The collar 14 may be omitted and the pin 12 then engages a longer slot in the plate 17.

If it is desired that n d >2.162-0.0090v, the La 2 O 3 , Ta 2 O 5 , and ThO 2  must total at least 15 per cent, and a suitable weight percentage range for the composition is SiO, 10-12, B 2 O 3  14-20, La 2 O 3  18-22, ThO, 16-18.5, ZrO, 0-8, CdO 18-20, BaO 10-12. If n d  is to be considerably greater than 1.875-0.00422v, the SiO 2  should not exceed 20 per cent. To obtain the highest chemical resistance the B 2 O 3  maximum should be 20 per cent, the content being kept lower the higher the refractive index required. The La 2 O 3 , Ta 2 O 5 , ThO 2  content is kept below 30 per cent as far as possible. The ZrO 2 , CdO, BaO content is increased to more than 35 per cent to give high refractive index with low rare earth content, the ZrO 2  being kept at 6 per cent at most to increase chemical resistance. The BaO preferably does not exceed 25 per cent. High refractive indices may be obtained without high contents of rare earths by adding WO 3 , the minimum La 2 O 3 , Ta 2 O 5 , and ThO 2  then being 10 per cent. If n d  does not greatly exceed 1.875-0.0042v a suitable weight percentage range is, SiO 2  16.3-16.6, B 2 O 3  16.8-17.2, La 2 O 3  9.0-10.9, ZrO 2  8.7-8.9, CdO 17.9-18.3, BaO 29.4-30.0.
