A method for pressing a liquid extract out of a material to be pressed. The material to be pressed is supplied to a screw press and is transported along a pressing path in the screw press, and a pressing pressure is applied to the material to be pressed. The screw press is supplied with an extraction agent (e.g., carbon dioxide) which is discharged from the material to be pressed together with the extract. The carbon dioxide is supplied to the screw press in the form of dry ice pellets. The dry ice is mixed with and transported together with the material to be pressed through the screw press along the pressing path. The dry ice is converted into liquid or supercritical carbon dioxide, which dissolves in the extract and reduces the viscosity thereof and which effectively cools the material to be pressed in the screw press.

METHOD AND DEVICE FOR SEPARATING A GAS MIXTURE CONTAINING DIBORANE AND HYDROGEN
In order to separate diborane from a gas mixture containing diborane and hydrogen, the gas mixture is normally cooled in a storage tank using liquid nitrogen, wherein the diborane freezes out. In order to enable an extensively continuous separation of the diborane from the gas mixture, according to the invention, the gas mixture is brought into thermal contact with a liquefied gas in a heat exchanger, which liquefied gas is held at a pressure such that the diborane is liquefied by the thermal contact with the coolant, and the liquefied diborane is then discharged from the first heat exchanger and supplied to a storage tank. In a downstream, second heat exchanger, the diborane remaining in the gas mixture can then be caused to freeze out.

A cooling system using carbon dioxide as a coolant comprises a cooling chamber for storing products to be cooled during transport and a cooling unit for cooling the atmosphere in the cooling chamber. The cooling chamber and the cooling unit are mounted on or integrated in a cooling vehicle like a truck, a railway wagon or a ship. The cooling unit comprises a carbon dioxide storage compartment and at least one cooling channel through which air is led from and to the cooling chamber. The carbon dioxide storage compartment and the cooling channel are separated from each other by a thermal well-conducting but gas-tight plate serving as a heat exchanger between the carbon dioxide in the carbon dioxide storage compartment and the air in the cooling channel.
When welding with a consumable wire electrode, current contacting occurs when the electrode wire passes by a readily electrically conductive contact element. In order to improve the current contacting and reduce the wear of the contact element in particular, the invention proposes subjecting contact elements to a cold treatment prior to using same. The cold treatment has a cooling phase during which the temperature of the contact element is reduced to a lower target temperature, a subsequent holding phase in which the contact element is substantially held at the target temperature, and a final heating phase, in which the contact element is brought to an upper target temperature. The use of contact elements treated using the method according to the invention leads to a substantial increase of the wear resistance compared to untreated contact elements.

In a method for producing nitric acid, nitrogen oxides are first created in an ammonia combustion plant (2) and are cooled in a condenser (3), thereby producing a solution containing nitric acid. The solution containing nitric acid is then supplied to at least one absorption tower, (4, 5), in which the nitrogen oxides are brought into contact with water and oxygen, wherein the nitrogen-containing gas mixture reacts at least partially with the water and the oxygen, forming an aqueous solution containing nitric acid, which solution collects at the bottom of the absorption tower, (4, 5) and is then compressed and supplied back to the absorption tower (4, 5) via a line (12, 14, 21). To minimise the concentration of nitrogen oxides in the waste gas of such a plant and to increase the efficiency of the process, according to the invention ozone is fed into a connection line (12) which leads from the condenser (3) to a first absorption tower and which conducts the solution containing nitric acid.
For the transmission of electrical current, determined superconducting current carriers are accommodated in a cryostat, in which they are cooled with an undercooled cryogenic cooling medium, e.g. liquid nitrogen. The current carrier is electrically connected at the ends thereof to two normally conducting current supply means. The cooling medium is undercooled from a storage container to a temperature below its boiling temperature and supplied to the cryostat via a cooling medium inlet, brought into thermal contact with the superconducting current carrier, and subsequently discharged via a cooling medium outlet of the cryostat. According to the invention, the cooling medium from the cryostat is to be used for cooling at least one of the normally conducting current supply means.

Device for cooling a consumer with a super-cooled liquid in a cooling circuit
A super-cooled liquid medium, preferably super-cooled liquid nitrogen, is pumped through a sub-cooler and cooled by the same medium that evaporates in the vacuum. This super-cooled nitrogen is used as coolant for a consumer. If a small amount of heat is emitted by the consumer to the nitrogen, the liquid medium can be guided in the circuit wherein the sub-cooler is arranged. For compensating volume fluctuations, such a circuit requires a compensation vessel, which is very expensive and can only be operated in the presence of a super-cooled medium when either a part of the medium is heated using external energy, or an inert gas which boils at very low temperatures is used as a pressure compensation medium. According to the disclosure, when a supply container for the liquid medium is integrated into the cooling circuit and used as a compensation vessel, a separate compensation vessel is not required.
