Abstract: A method and apparatus for producing a pipe transports first and second sets of chill moulds respectively along first and second endless paths, the chill moulds of each set being so transported one after another, and the endless paths being positioned such that junction faces of the respective chill moulds of the respective sets are positioned against each other in a pipe moulding zone of the endless paths. So positioning the respective chill moulds of the respective sets also defines outer surfaces thereof that are opposite the junction faces and outer surfaces that extend along edges of the junction faces at least generally in the direction of the transporting of the chill moulds. The chill moulds are locked together in the pipe moulding zone with locking surfaces respectively on the outer surfaces of the chill moulds that extend along edges of the junction faces, locking pieces having substantially the same lengths as the chill moulds and U-shaped cross sections, and locking piece transporting means for transporting first and second sets of the locking pieces one after another respectively along two locking-pipe endless paths at the same rate as the chill moulds are transported. The locking-piece endless paths are positioned in the pipe moulding zone such that insides of the U-shapes of the locking pieces engage and lock together the locking surfaces of the chill moulds in the pipe moulding zone. The outer surfaces of the chill moulds that are opposite the junction faces thereof are also pressed while the chill moulds are in the pipe moulding zone for pressing the chill moulds together in a direction perpendicular to the junction faces of the chill moulds.

Abstract: In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.

Abstract: The intrastromal corneal ring (ICR) is adjustable in thickness and has an elongated, flexible, preferably transparent or translucent body which forms a circle. The ICR is of a size such that it can be inserted into a human eye and is comprised of a material which is compatible with human ocular tissue. The thickness of the ring can be adjusted so that it is not necessary to stock a plurality of different rings of different sizes to be used in connection with a method of adjusting the shape of the cornea of the eye. A plurality of different embodiments of ICRs are disclosed each of which are adjustable in terms of their thickness. The thickness may be adjusted prior to the insertion of the ICR into the cornea and may not be further adjustable after insertion. However, in accordance with preferred embodiments the ICR is inserted at a thickness which is believed to be proper and may thereafter be further adjusted in order to precisely define the desired thickness and thereby more precisely adjust the shape of the cornea and focus the light entering the eye on the retina.
