In the turbogenerator rotor shown, the inner surfaces of the shoulders 32 are inclined to the circumferential direction, and the centrifugal pressing of the bars 24 on to these surfaces when the rotor is running causes a reaction component F to be applied to the bars, thereby forcing them together. In the rotor of Fig. 4 (not shown), conductive wedges (40) are positioned between the damper bars (24), and the wedges are centrifugally forced outwards into firm engagement with the sides of the bars during operation of the rotor.

Title: Improvements in or relating to a method and apparatus for threadrolling and similar shaping operations
IPC: B21H3/04
Filed: 1959-12-16
Abstract: 888,021. Thread-rolling; spinning; shearing; turning. HOFER, R. Dec. 16, 1959 [Dec. 17, 1958], No. 42742/59. Classes 83 (3) and 83 (4). In a method of shaping workpieces, e.g. thread-rolling, spinning, turning and parting-off, while the workpiece rotates about an axis with no axial movement, shaping tools having a plunger-feed motion imparted thereto are each subjected to a primary and a secondary working force in such a manner that two resulting shaping forces are applied to the workpiece, the two forces being directed towards each other in a line of application passing through the said axis of rotation and extending at right-angles thereto, the plunger-feed motion of the tools being capable of analysis into a movement of rotation of the working forces about their point of application relatively to said common line of application of the shaping forces and simultaneous rotation of said line of application about said axis of rotation. Thread rolls 12, Fig. 5, are freely rotated by a workpiece mounted either in a lathe or checked to the spindle of a special purpose machine. Radial force is applied to feed the rolls towards the axis of the work by eccentrics 13 which are phased 180 degrees apart and act in synchronism so that the points of contact of the rolls 12 remain diametrically opposite at all instantaneous positions and are fed equally into the work. The point of contact of each roll 12 with the work also moves circumferentially during the radial feed motion. The distance between the rolls is adjusted by a screw 29, Fig. 4, mounted in a block 26 attached to an upper pivoted arm 19 which screw-acts on the head 31 of a pin 32 supported by a spacer 36 and a block 27 attached to a lower pivoted arm 19, rotation of the screw resulting in a pivoting of the arms 19 about a pin 21 journalled in a U-shaped carrier member 22 to provide a fine adjustment of the rolls. Various diameters of work and rolls can thus be accommodated according to the size of the spacer 36. During pivoting of the arms 19 synchronism is maintained between the rolls 12 by a gear train 41, 42, 43, the gears 41 engaging internal gears 15 concentrically attached to the rolls 12 and the eccentricity of the gears 41 with respect to the gears 15 being equal to that of the eccentrics 13. The shafts 13<SP>1</SP> of eccentrics 13 pass freely through the gears 41 and are oscillated in synchronism through gearing 45, 46, 47, Fig. 7, by a balanced rack drive comprising racks 49, 54 engaging the gear 47 freely mounted on the pin 21. The racks are driven by the reciprocation of a slide 52. The thread is completely formed during one oscillation of the eccentrics from the position shown in Fig. 1 (a) to that shown in Fig. 1 (c).

Abstract: The invention comprises (1) a process for the preparation of the 11,18-cyclohemiacetal of an 11b  - hydroxy - 18 - oxo - pregnane compound wherein a 20-ketal of an 18,20-dioxo-pregnane compound which contains an 11a -hydroxy group, an 11a - or 11b -acyloxy group or an 11-keto group is treated in an anhydrous non-acidic organic solvent with a strong acid, in the 18-acetal so formed, if desired after reketalization of the liberated 20-oxo-group, the 11-oxygen function is converted by a known method into an 11b -hydroxyl group, and in the resulting compounds any ketal and acetal groups are split hydrogenolytically or by acid hydrolysis; and (2) 18-acetals of 3-oxygenated 18,20-dioxopregnanes and -isopregnanes containing an 11a -hydroxy group, an 11a - or 11b -acyloxy group or an oxo group, and their 20-ketals.  Reketalization of the 20-oxo group in process (1) also generally yields an isopregnane in addition to the required pregnane.  The last step of process (1) may be performed with a lower aliphatic carboxylic acid and a strong inorganic acid to give mixtures of the cyclohemiacetal and its acylate, which can be further acylated or hydrolysed.  The starting materials may further contain free or functionally converted hydroxyl or oxo groups, alkyl groups or halogen atoms as substituents in the nucleus, the 17-side chain and the 10-methyl group; or they may be 19-nor compounds; and they may contain double bonds.  Preferably they are D 4-3,18-dioxo-11-oxygenated - 20,20 - alkylenedioxy - pregnenes or their D 5-3-alkylene ketals.  The 3-oxygen function in compounds (2) may be a free esterified or etherified hydroxyl group or a tree or ketalized oxo group.  In examples: (1) 3,3:20,20 - bisethylenedioxy - 11b ,18 - dihydroxy - D 5 - pregnene is oxidized to 3,3:20,20 - bis-ethylenedioxy - 11,18 - dioxo - D 5 - pregnene, and this by the process of the invention is converted to 3,3:18,18 - bisethylenedioxy - 11,20 - dioxo -D 5-pregnene, this to a mixture of the diols epimeric in the 20-position and this to 3-oxo-11b ,18:18,20b  - bisoxido - D 4 - pregnene and its 20a -epimer; (2) the dioxo starting material of (1) is converted by the process of the invention to the 3,3:18,18-bisethylenedioxy product of (1) and the corresponding 3,3:18,18:20,20-triethylenedioxy compound and the corresponding iso-pregnane, the second of these products to the corresponding 11b -ol and this to the (18,11b )-cyclohemiaceta of 3,18,20-trioxo-11b -hydroxy-D 4 - pregnene (21 - desoxyaldosterone), and the iso-compound to similar iso-pregnane products; and (3) the first product of (1) is prepared similarly and is hydrolysed in the same process to 3,11,30 - trioxo - 18,18 - ethylenedioxy - D 4 - pregnene.

[Also in Division G3] A fluidic control system for a gas turbine comprises a proportional amplifier 5 fed at 17 with a static reference pressure corresponding with either a maximum or minimum limit for the compressor pressure, and at 18 with the actual pressure existing in the compressor. The output legs 21, 22 of amplifier 5 are connected via digital amplifiers 8, 6, having exhaust legs 24, 16, to the input 14 of a proportional amplifier 7 the control jets of which are also fed by output legs 21, 22. Thus the outputs 27, 28, which are connected to the engine's fuel control circuit, are operative only when the compressor pressure is outside the predetermined limits, the pressure difference between outputs 27, 28 is proportional to the amount the compressor pressure varies from these limits. Amplifier 6 has a second control jet 30 which receives a signal to isolate outputs 27, 28 if the engine overheats. Fig.1 (not shown) illustrates a modification in which leg 24 is connected to a control jet of amplifier 6 opposing jet 32, and control jet 30 is dispensed with.
