摘要： A hollow rotary member such as a roller, extruder or the like, requiring constant temperature control by a fluid circulating therethrough, has a hollow shaft with radial inlet and outlet ports communicating with respective compartments of a stationary coupling sleeve surrounding same, the compartments being bounded by sealing rings engaging the shaft. In order to facilitate the introduction of the shaft into the sleeve without damage to the sealing rings, the shaft ends in an extremity of reduced cross-sectional area whose noncircular outline consists of convex sections smoothly merging into one another.

摘要： A combined ski boot and ski binding. The ski boot has a lower portion made of pliant material integral with an upper portion made of rigid material. The ski binding has a sole plate that is releasably connected to the top surface of a ski with side edges of the sole plate extending generally parallel to the longitudinal axis of the ski. Fastening members are hingedly connected to the side edges of the sole plates. A cooperating fastening mechanism releasably interconnects the fastening members with the upper portion of the ski boot.
