Title: A shrunk-on joint between cylindrical parts
IPC: H01H9/44
Filed: 1960-11-04
Abstract: 951,097. Jointing. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Nov. 4, 1960 [Nov. 16, 1959], No. 37968/60. Heading B3V. A shrunk-on joint between two concentrical cylindrical parts is characterized by zones of different degrees of shrinkage in the axial direction. In an embodiment an inductor cap 10 is shrunk-on to an inductor rotor 11 of a turbo-generator. The cap has a shoulder 15 for engaging a shoulder 16 on the rotor. This accurately locates the cap on the rotor and a split ring 12 holds the cap in position. The main part of the joint is effected by a shrink fit between the inner surface of the cap and reduced portions 13 and 14 on the rotor, the fit at the portion 13 adjacent the shoulders 15, 16 having a higher degree of shrinkage than the remote portion 14, e.g. in a ratio of 3 : 2. This ensures that a fixed shrunk-on connection is first established adjacent the shoulders 15, 16 and prevents any axial shrinkage from drawing them apart. A zone 17 free of shrinkage pressure is provided between the portions 13 and 14.

Title: Improvements in or relating to magnetohydrodynamic generators

Abstract: 1,002,842. Generators operating by electromagnetic interaction with fluids. M-O VALVE CO. Ltd., and R. B. DYOTT. Oct. 4, 1963 [Oct. 8, 1962], No. 37977/62. Heading H2A. The working fluid in a magnetohydrodynamic generator is velocity modulated so that portions of the plasma are accelerated to produce bunching of the particles (ions, electrons) in the region of the magnetic field and thus produce a pulsating electrical output. As shown, air is compressed at 1 and passes through preheater 2 to the combustion chamber 3 where fuel is burnt to produce a high pressure, high velocity stream of gas which is expanded into duet 4 through nozzle 5. A first opening in the duet wall communicates with acoustic resonator 6 where an oscillation is set up by means of loudspeaker 7 which velocity modulates the flow of gas in the duet. A further resonator 8 having the same oscillation frequency as resonant chamber 6 and having its opening into the duet spaced from the first opening by a distance such that a bunching of plasma particles occurs at this point and is amplified by resonator 8. The magnet 9 and electrodes 10 are spaced along the duct by an amount such that bunching of the particles again occurs in this region to obtain an optimum output. In a modification loudspeaker 7 may be omitted and the resonators acoustically coupled together to provide an oscillatory arrangement. Further methods of velocity modulating the gas flow in the duct include making periodic changes in the fuel supply or varying the profile of the nozzle 4 by periodic injection of an inert gas.
