Abstract: The present disclosure relates to a blind fastener and a method of installation thereof. The blind fastener comprises a sleeve and a mandrel. The sleeve comprises a first sleeve end, a second sleeve end, and a cavity extending from the first sleeve end to the second sleeve end. The mandrel is configured to be at least partially received by the cavity of the sleeve. The mandrel comprises a first mandrel end disposed adjacent to the first sleeve end and comprising an enlarged portion having a diameter greater than a diameter of the cavity, a second mandrel end comprising a pull region, and a shank region extending intermediate the first mandrel end and the second mandrel end. The pull region comprises an axial length no greater than four times a diameter of the shank region and is configured to be engaged by an installation tool.

Abstract: A clutch assembly connectable to an electric motor and to another rotating unit includes a housing securable at one end to the housing of the electric motor and securable at the opposite end to the housing of the other rotating unit. A driven body within the clutch housing is rotatably mounted in a bearing supported in the clutch housing and is connectable in a driving manner to the other rotating unit. A drive body is connectable to the electric motor so as to be driven thereby and has radially movable centrifugal weights which engage and drive the driven body when the rotational speed of the drive body exceeds a predetermined value and which are disengaged from the driven body when the rotational speed is below the predetermined value.
