Abstract: A rotor for an electric machine includes a rotor yoke having a plurality of axial winding slots distributed on an outer periphery of the rotor yoke; a winding bar disposed in one of the plurality of axial winding slots, the winding bar having at least one winding end emerging axially from the rotor yoke so as to form an end winding; and a retaining device including a plurality of radial bolts, each of the plurality of radial bolts having a head fixedly connected to a shank, wherein the retaining device retains the end winding against a centrifugal force acting on the end winding.

Abstract: A rotor for an electrodynamic machine includes a laminated core having a plurality of lamination segments arranged in series in an axial direction, wherein the laminated core includes cooling ducts formed by duct spacers disposed between axially adjacent lamination segments, wherein the duct spacers are configured to resist centrifugal forces acting on the duct spacers and are supported by axial bolts extending through the laminated core in the axial direction.

Abstract: The present invention relates to a composition for implantation in the subretinal space of an eye, the composition including amniotic membrane, which may be cryopreserved human amniotic membrane, and a plurality of retinal pigment epithelial (RPE) cells or RPE equivalent cells present at the amniotic membrane. The amniotic membrane may be intact, epithelially denuded, or otherwise treated. The invention includes the use of amniotic membrane for the culturing of RPE cells thereon, forming a surgical graft for replacement of Bruch's membrane as a substrate, and for the transplanting of RPE cells to the subretinal space. The composition does not elicit immunological reactions to alloantigens or to RPE specific autoantigens; and exerts anti-inflammatory, and angiogentic, and anti-scarring effects. The invention includes methods and kits for making or using composites including amniotic membrane and RPE cells. Also disclosed is a device for harvesting RPE cells.
