Abstract: Apparatus for transferring at least partially finished packets containing cigarettes or other rod-shaped smokers' products from a lower level, where the packets are advanced along a horizontal path toward a stationary transfer station, into the receptacles of a rotary indexible conveyor at a higher level, has an elevator with two superimposed components which clamp a packet during lifting from the lower level to the conveyor. A packet which is in the process of advancing to or has reached the upper level is engaged by one of several holders which are associated with the receptacles and hold the adjacent packets against undesirable displacement, at least during the initial stage of indexing of such packets from the transfer station.

Abstract: A device for cooling a magnet system, especially in an installation for nuclear spin tomography which magnet system comprises several annular magnet coil windings which are made of ribbons of normal conducting material and are connected at their end faces over a large area to cooling elements in a heat conducting manner, the cooling elements cooled by a cooling medium flowing in coolant lines under forced flow. To assure an effective and reliable cooling of the coil windings on each end face of a magnet coil winding, a predetermined number of identically designed cooling elements uniformly distributed in the circumferential direction is cemented on, each cooling element comprising at least a heat conduction plate of annular sector shape which is provided with a predetermined number of slots uniformly distributed in the circumferential direction and to which the coolant line is connected over several turns in a heat conducting manner.
