Abstract of the Disclosure A device for transferring helium between rotating and non-rotating members includes first and second transfer reeds and a cylindrical sleeve. The cylindrical sleeve is provided between the first and second reeds and extends substantially throughout the region of axial overlap of the reeds. One of the reeds rotates with the rotating member while the other reed is fixed. Third and fourth coaxial transfer reeds may be provided for the transfer of gaseous helium. The third and fourth reeds concentrically surround the first and second reeds with one of the reeds rotating and the other reed being fixed. Cylindrical sleeve members are provided between adjacent reeds with the sleeve members all rotating with the rotating member. The sleeve members are connected to one another at opposite ends of the intermediate sleeve member. Guide means may be provided to cancel a component of rotation of the gaseous helium. A bayonet fixing device releasably attaches the cylin- drical sleeve to the rotating member. - 1 -
