Abstract: Molten steel, normally exposed to an atmosphere of air, is protected against pick-up of impurities by placing carbon dioxide gas in such quantities and in such proximity to the surface to cause dissociation of the carbon dioxide at a rate which furnishes an atmosphere of carbon monoxide and gives off a negligible amount of oxygen to the steel, thus providing a gas barrier or shroud isolating the steel from the surrounding atmosphere and preventing pick-up therefrom of oxygen, nitrogen or hydrogen. This method may be applied to protecting steel being transferred from a ladle to a mold, or from a ladle to a tundish and from the tundish to a mold in continuous casting. In a method where a number of shrouding operations are carried out in series, carbon dioxide vapor, under pressure, is bled, in increments, from a storage vessel containing a body of liquid carbon dioxide in overlying ullage space containing vapor. Each increment is superheated, after it leaves the vessel, and is ultimately expanded and dispersed at ambient temperature to form the shroud. As each increment of vapor is removed from the vessel, it is replaced by withdrawing liquid carbon dioxide, vaporizing it and returning it to the ullage space.

Abstract: A hard foreign body in a stream of cut crop being moved by a conveyor in an agricultural machine to a crop comminuter of the machine is detected by first compressing the stream of cut crop transversely of its displacement direction between a pair of feed elements one of which is movable toward and away from the other and generating an actual-value output corresponding to the acceleration of the movable element toward and away from the other element. This output is compared with a set point corresponding to an acceleration level not normally exceeded by the element when the crop stream contains no hard foreign objects. An error signal is generated when the actual-value output exceeds the set point. When the error signal is issued advance of the conveyor is stopped and/or a warning is issued. The actual-value output is only generated when the acceleration of the movable feed element exceeds a predetermined limit. The actual-value output is a voltage and the set point is also a voltage.

Abstract: Gas mixtures are purified, especially for removal of gases which pollute the environment, such as nitrogen oxides, carbon monoxide, hydrocarbons and/or sulphur oxides from exhaust gases and flue gases, in the liquid phase by means of catalysts. According to the invention, substantial activation of the catalysts used in such processes is achieved by bringing the gases into intensive phase contact with a contact fluid containing a catalyst suspended or dissolved therein, by forming a foam from the gases and the contact fluid and allowing the reaction to proceed in the foam phase thus formed. In this way, it is possible to remove 90 to 99% of the polluting gases, present in the exhaust gases, in one working step.

Abstract: A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the units(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.
