    Abstract: In an impeller element of a radial inflow gas turbine the shape of the blades and the outer profile of the hub are such as to make the impeller symmetric about two planes, one through the axis of rotation and one normal to it, the impeller thus deviating from the conventional shape of radial inflow gas turbine impellers, which to a considerable degree has been adapted to the theoretical path of the gas.

    Abstract: A rotary gas-handling machine and rotor therefor in which the number of puffs of gas affecting the rotor so as to tend to excite vibrations therein on each revolution will be such that for the designed speed of operation of the rotor the resulting frequency of excitation puffs will be different from each of the resonant frequencies of the rotor, such as the resonant frequency for ''''saddle'''' vibration, blade vibration, rotational and outer edge vibration of the shroud, etc. The excitation frequency is also made to differ from one-half of each of the resonant frequencies. In the case of such a machine in the form of a turbine the number of excitation puffs per revolution is determined by the number of circumferentially spaced nozzles carried by the housing to direct the gas against the rotor, while in the case of a compressor rotor the number of excitation puffs per revolution is determined by the number of blades. The blades and the shroud are preferably made thicker adjacent their inner extremities both to deter vibration by inherent stiffness of such thicker members and to change their natural frequencies by the mass of the thickened members. The same sort of structure makes the shroud more resistant to vibration by stiffening an important component of the ''''spring'''' of the resonant mode while strengthening it against shear. Another expedient is to cause the blades to protrude from the wheel outwardly past the plane of the eye of the shroud and be joined to the hub out beyond such plane so as to provide bracing for both the shroud and the disk of the rotor against axial vibration.

    Abstract: A turbine wheel or rotor for operation by gas streams containing entrained particles of liquid or solids or liquid streams containing bubbles, such as in power recovery from dust-bearing gas or boiling liquid. The passageways between blades of the rotor are so shaped that as the flow progresses radially inwardly and its circumferential motion with the wheel is retarded and centrifugal force on such particles therefore decreases, there will be at first a radial and small negative relative tangential component of flow, and the radial inward rate of flow component and hence drag on such particles opposed to such centrifugal force will decrease accordingly to maintain a substantial balance of radial forces on such particles. Also the passages are curved so that they will substantially parallel the circumferentialaxial flow rate component as the decrease in radial flow rate component is replaced by increase in circumferential flow rate component relative to the rotor, while the axial flow rate component is maintained at or increased to a value to move the stream through the axial extent of such passages in such time as is required for the circumferential flow rate component relative to the rotor to substantially equal and oppose the circumferential velocity of the outlets of such passageways. Thereby the drag on such particles to cause them to impinge on the blades will be minimized. The words ''''tangential'''' and ''''circumferential'''' are used synonymously.
