Abstract: A melt flow pipe (15) is arranged penetrating a vacuum container (14). The melt flow pipe is made of a porous material having pores which allow premeation of gases but does not allow permeation of melts (2) such as molten metal, molten slag, and molten matte. And, in the wall of this melt flow pipe are buried a pipe-like member (16) wherein a cooling medium flows in a form of coil. 
     As the melt contact the external surface of the flow pipe and this section is exposed to a vacuum state, gases in the melt or gases generated through reactions between the melt and the porous member pass through the porous flow pipe to the internal surface side and removed. When the melts flows therein, the flow pipe is cooled by a cooling medium, so that degasification of the melt can be made continuously.

Abstract: L'invention se rapporte à un circuit de temporisation, dans lequel des transistors MOS (21, 22) pour résistances servant à commander la durée de temporisation d'un inverseur CMOS (26) sont insérés entre la source de l'inverseur CMOS (26) et les potentiels d'alimentation (GND, Vdd), et les sources correspondantes des transistors MOS (21, 22) sont connectées respectivement aux potentiels d'alimentation (GND, Vdd). Ainsi, en modifiant les courants de drain des transistors MOS (21, 22), on modifie respectivement leurs tensions de commande (Vn, Vp). La capacité de commande de l'inverseur CMOS (26) est modifiée en conséquence, ce qui permet de réguler la durée de temporisation de l'inverseur (26). En outre, étant donné que les sources des transistors MOS (21, 22) sont connectées aux potentiels d'alimentation (potentiels fixes) (GND, Vdd) respectivement, on obtient la stabilité de la durée de temporisation même en cas de perturbations.

Abstract: In a method for producing laminated plastic articles consisting of a base layer of thermoplastic material and at least one cover layer 7, flowable thermoplastic material 12 is compression-moulded as base layer between a lower 2 and an upper 5 mould-half with the cover layer laid in between the mould-halves. In order to prevent the mould cavity constantly changing during the compression-moulding of the flowable thermoplastic material or the melt and correspondingly the melt having to change its flow direction again in certain mould sections, which can result in undesired folds and distortions during compression- moulding with the cover layer, it is proposed first to move the mould- halves together as far as their end position, with the interposition of the cover layer and with the inclusion of the mould cavity representing the finished base layer. Subsequently, the compression- moulding operation is carried out in such a manner that a partial piece, representing a displacement body 9, of the lower mould-half 2 is pressed from a lowered position, in which a recess 11 receiving the melt is formed, by means of a lifting piston 10 into an upper position, in which the surface of the displacement body essentially flush with the mould surface of the lower mould-half.
