Abstract: A non-positive-displacement machine (10), particularly a turbomachine for producing a mass flow, having a central housing part (11) inside which a turbine shaft is mounted. A turbine housing is mounted on the central housing part (11) on a turbine side and a compressor housing is mounted on the central housing part (11) on a compressor side. The spiral channels (17, 18) required for the compressor side and for the turbine side can be arranged in a partial area inside the covers (15, 16) and at least in one partial area inside the central housing part (11). This permits the contours, which are required for the spiral channels (17, 18) and which are geometrically complex, to be constructed in the central housing part (11).

Abstract: An edible greeting card includes two edible leaves. Each leaf of the card is imprinted with a message and/or design which is suggestive of a celebratory event and each leaf is individually wrapped in clear plastic. The two leaves are coupled to each other by a hinge which may be formed from a strip of adhesive tape or from a folded cardboard member which embraces an edge of each leaf. The wrapped and hinged leaves are preferably packaged with at least one self-adhesive label upon which the sender may write a personal message and affix the label to one of the leaves. The edible greeting card and the self-adhesive label are preferably packaged in a plastic box which serves as the "envelope" for the greeting card.
