Abstract: A turbine generator comprising a turbine rotor comprising a hub and one or more blade stages. Each stage comprising a circumferential array of rotor blades in driving engagement with the hub. A turbine stator comprising a hub and one or more vane stages, each stage comprising a circumferential array of vanes. The turbine rotor and turbine stator being concentrically arranged about a common axis to define an annular flow path. The vane stages and blade stages being axially spaced along the axis and having one or more magnets arranged on the rotor. A generator stator concentrically aligned with the turbine rotor and turbine stator and one or more magnets arranged on the rotor. In use, when the turbine is driven to rotate about the axis, the or each of the magnets on the turbine rotor rotate relative to the generator stator in order to generate electric power.

Abstract: A fail-safe electromagnetic linkage has a support device for a valve head, and an actuator component actuable by an actuator. The support device is coupled to the actuator component while power is supplied to the electromagnet and decoupled from the actuator component while power is not supplied to the electromagnet. The assembly further comprises a return mechanism configured to drive the support device relative to the actuator component if power is not supplied to the electromagnet.
