A tube section for constructing a tube for underpressure applications with an incircle having a diameter of at least 2 m and to an evacuated tube transport system tube produced therefrom.

Tube section for evacuated tube transport system

A method for producing a tube segment and a tube for an evacuated tube transport system and a method for producing the tube segment.

Tube segment and tube for evacuated tube transport system

A method for the separation of a dispersion of molten aluminium and solid inclusions formed from a melt of aluminium containing one or more foreign chemical elements. Molten aluminium surrounding the solid inclusions is at least essentially replaced by a molten salt.

Method for the separation of molten aluminium and solid inclusions

The invention relates to a method for fractional crystallization of an at most partially solidified molten metal, in which a layer of at most partially solidified molten metal having an upper surface and a lower surface is divided into a series of compartments communicating with each other, in which the metal is stirred in at least some of the compartments, and in which crystals formed and/or existing in the layer of metal are selectively transported in a predetermined direction and molten metal is selectively transported in the opposite direction.

Method for fractional crystallisation of a metal

Method of cooling an at most partially solidified molten metal during fractional crystallization wherein metal crystals formed have a purer composition than that of the molten metal. Salt in solid form is used to cool the at most partially solidified molten metal.

Method of cooling molten metal during fractional crystallisation

The invention relates to a method for the purification of a molten metal containing one or more foreign elements. The molten metal is cooled to a eutectic temperature to simultaneously form purified metal crystals and crystals containing at least one foreign element, and at least some of the crystals containing at least one foreign element are separated from the purified metal crystals by using a solid-solid separation technique.

Method for the purification of a molten metal

The invention relates to a method for controlling the proportion of aluminum crystals in a mixture of molten aluminum alloy and aluminum crystals. The electrical resistance of the mixture is determined with the aid of a four-point measurement. With the aid of the measured electrical resistance, the proportion of crystals in the mixture can be kept constant within narrow margins. The invention also relates to a device for carrying out the method.

Method and device for controlling the proportion of crystals in a liquid-crystal mixture

The invention relates to a method for fractional crystallization of an at most partially solidified molten metal. According to the invention a layer of at most partially solidified molten metal to be crystallized is cooled by a layer of cooling liquid, which is present above and/or below the layer of at most partially solidified molten metal so as to crystallize the molten metal.
