摘要:
A conveyor belt of a continuous strip-casting device for casting strips of metal, particularly steel, which belt is guided by a driven drum and a drum horizontally adjacent to the driven drum and displaceable for tensioning the belt. The belt rests in this connection on a support arranged between the drums and the side thereof facing away from the cast strip is cooled. The conveyor belt has, on the side remote from the cast strip, uniformly distributed blind holes. The blind holes are separated by webs of a minimum width. The total surface area of the webs is 0.15 to 0.4 times the total surface area of the belt. The bottoms of the blind holes have a wall thickness which, upon heating by the cast strip with simultaneous cooling of the inside surface of the blind holes, permits a bulging of the bottom of less than 1 mm.

An incubator for premature and newborn infants includes a housing defining a first housing portion and a second housing portion. A transparent hood is mounted on the housing so as to define an enclosure with the first housing portion for accommodating the infant therein. Conditioning equipment for conditioning the air in the enclosure is mounted in the second housing portion. An exchangeable support is removably mounted in the first housing portion and is adapted for supporting the infant thereon. The second housing portion is partitioned from the air in the enclosure by means of an insert to permit those components which communicate with the air in the enclosure to be thermally disinfected. The support and the insert are configured as removable individual components resistant to temperatures of a thermal disinfection.
