  • Flame cutter
    Patent number: 4280687
    Abstract: A cutting machine for severing a moving strand portion includes an elongated support; the strand portion normally moves near the support in one direction of elongation thereof, and a carriage may be operably moved on the support in the one direction and in an opposite direction. A cutter is disposed on the carriage, and the movement of the carriage is synchronized with that of the strand by a rotatable roll in operative driven relationship from the strand. The rotation of the roll is selectively converted into a translatory motion of the carriage, so that the strand may be cut by the cutter, while it is moving in synchronism therewith.

  • Process for the treatment of water
    Patent number: 4255257
    Abstract: In a process for the treatment of water with ozone a partial current of treated water is contacted under pressure in a packed column with an oxygen-ozone mixture from an ozonizer to oxidize water contaminants and to improve their flocculation. The portion of oxygen which has not dissolved in the water in the packed column is recycled into the ozonizer and the treated partial water current is mixed again with water to be treated. The pressure in the column is adjusted in dependence on the nitrogen content of the water to be treated. By this measure is ensured that the quantity of nitrogen escaping from the water and contained in the cycle oxygen permits an optimum operation of the ozonizer. The nitrogen content in the cycle oxygen is preferably kept below 10% by volume.

  • Process for water treatment
    Patent number: 4252654
    Abstract: A process for the treatment of water in which at least a partial flow of the water is brought into contact under pressure in a packed column with an ozone-oxygen mixture from an ozonizer with the ozone and a portion of the oxygen being dissolved in the water and the undissolved oxygen being returned to the ozonizer and with the charged water being withdrawn from the column, includes branching off a partial flow from the column water to a water jet-gas compressor in which the ozone-oxygen mixture from the ozonizer is adsorbed and compresed and mixed with the partial flow after which the mixture of water, ozone and oxygen is led into the base of the packed column.
