Abstract: A system and a method for cleaving water by means of hyperpolarization, the system has a first electrode and at least one additional electrode; at least one porous ferroelectric layer arranged between the first and the additional electrode; as well as an AC voltage or pulsed DC voltage source. With this method it is possible to cleave the water economically into hydrogen and oxygen and obtain gases for technical purposes.

Abstract: The present invention relates to a system and a method for cleaving water by means of hyperpolarisation, the system comprising a first electrode and at least one additional electrode; at least one porous ferroelectric layer arranged between the first and the additional electrode; as well as an AC voltage or pulsed DC voltage source. With the method according to the present invention it is possible to cleave the water economically into hydrogen and oxygen and obtain gases for technical purposes.

Abstract: The material settling on the inside of the centrifuge drum during operation of centrifuges causes imbalances on account of the unavoidable nonuniform mass distribution, which imbalances lead to vibrations and the associated high level of solid-borne sound and bearing wear. The centrifuge drum shaft (15) is supported by an active (variable pressure) hydraulic bearing support (10) that is relatively simple in design and inexpensive to manufacture for this centrifuge application.

Abstract: 1,2-dichloroethane is continuously and completely removed and recovered from the off-gas obtained during the production of 1,2-dichloroethane by subjecting ethylene to an oxychlorination reaction with hydrogen chloride and oxygen. The off-gas is initially contacted with active carbon, then incinerated at temperatures higher than 900.degree. C. and ultimately freed from hydrogen chloride and chlorine, and the active carbon is freed from 1,2-dichloroethane and regenerated by treating it with hot steam. More particularly, the off-gas loaded with the 1,2-dichloroethane and having a temperature of 1.degree. C. to 10.degree. C. is heated to a temperature at least 20.degree. C. higher than the respective dew point of water and contacted with the active carbon.
