Abstract: A threaded fastener comprising a first threaded part defining an axis, A, from a first end to a second end thereof, the threaded part having a radially inwardly extending thread along a portion thereof between the first and the second end and a non-threaded portion between the thread and the second end The fastener also has a second threaded part defining an axis from a first end and a second end thereof and having a radially outwardly extending thread along a portion thereof between the first and the second end and a non-threaded portion between the thread and the first end. The fastener also includes a compressible part arranged to provide an axial load to one of the first and the second threaded parts when the parts are fastened together.

Abstract: A rotary electromechanical actuator, EMA, includes a rotary part for rotation about an axis and a fixed part relative to which the rotary part rotates. The EMA further includes: a hard stop assembly with one or more hard stop members mounted to the EMA fixed part and one or more abutment members mounted to the rotary part and arranged to contact the one or more hard stop members at a hard stop end rotary position of the rotary part relative to the fixed part. The EMA also includes a soft stop assembly with one or more moving soft stop members mounted to the rotary member and one or more stationary soft stop members mounted to the fixed part. The one or more moving soft stop members are arranged to contact the one or more soft stop members at a soft stop end position of the rotary part relative to the fixed part.

Abstract: A connection apparatus suitable for mounting on a structural element and connection to a port of a system or component in which the connection apparatus comprises a connector, a flange and a compressible biasing element is provided. The connector forms a longitudinally extending conduit having an axis (A) extending along the centre of the conduit, a port end adapted to be engaged with the port of a system or component, and a second end. The connector comprises a shoulder extending around the perimeter of the connector, and the shoulder extends around the perimeter of the connector in a direction substantially perpendicular to the portion of the conduit axis (as) around which the shoulder extends. The biasing element is adapted to at least partially extend around a portion of the connector adjacent to the shoulder.
