Abstract: The invention relates to a method for processing waste or biomass material into valuable products such as, for example, combustible gases, which is characterized in that(a) the waste or biomass material is subjected to a pyrolysis at a temperature of 350-650.degree. C., advantageously 450-550.degree. C.;(b) the gas released in the course of the pyrolysis is subjected--without condensation--to a cracking treatment at a temperature of 1100-1600.degree. C., advantageously 1200-1400.degree. C., under the influence of oxygen-rich gas introduced from outside and possibly of steam;(c) the residue liberated in the course of the pyrolysis is gasified under a pressure of 0.5-1.5 bar, advantageously 0.8-1.2 bar, at a temperature of 1200-1700.degree. C., advantageously 1400-1600.degree. C.

Abstract: Optical fibres are drawn from a solid preform which consists substantially of SiO.sub.2 and doped SiO.sub.2. After leaving the heating zone, the fiber is guided through a space having a laminar gas flow to restrict the temperature drop across the fiber so that no extra stresses are incorporated in the fiber upon cooling. A device for performing this method comprises a quartz pipe through which the fiber is guided and in which a laminar gas flow is maintained.

Abstract: A recuperative heat exchanger for gas-gas heat exchange at a temperature above 700.degree. C., comprising a refractory lined vessel having a vertically extending steel shell closed at top and bottom by respective ends, wherein the space within the vessel is divided into respective top and bottom end chambers and a heat-exchange chamber therebetween by top and bottom apertured refractory plates and the end chambers are connected by a plurality of substantially vertical tubes of refractory ceramic material extending between said plates.

Abstract: A system for recording/reading information, comprising interchangeable disc units and a drive unit. Each disc unit comprises a disc pack with at least one information disc which is contained in an enclosure comprising two covers which can move relative to each other and which are interconnected by connecting means. The drive unit comprises means for supporting and driving the information-disc pack and means for recording/reading the information on the information discs, means for releasing the connection between the covers, and means for moving the covers relative to each other.

Abstract: A disk unit (1) comprises a circular information disk (2) accommodated in an enclosure, at least one major wall (6) of the enclosure being formed with a slot (11) for an information write and/or read head of a disk drive apparatus, which slot is closed by means of a sliding plate (12) of a slot sealing device when the disk unit is disposed outside the drive unit, and which slot can be opened by sliding the sliding plate from the closed position to the open position when the disk unit is inserted into a drive unit. An actuating member for moving the sliding plate is constituted by a lever (13) which is journalled on the major wall (6) in which the slot (11) is formed, in such a way that a transmission ratio greater than unity is obtained between a free end (15) of the lever which is externally accessible to the drive unit and a second free end (16) which is connected to sliding plate (12).

Abstract: To permit the storage of large amounts of information on interchangeable rigid magnetic discs, the inner wall of a turntable recess and the inner wall of the disc central opening are accurately machined with tight dimensional tolerances, and a centering element cooperates with at least one of the inner walls via elastically deformable compensation means.
