Abstract: A system reclaiming contaminated water includes a heat exchanger that receives the contaminated water and converts at least a portion of the contaminated water into steam and collects at least a portion of the contaminants within the heat exchanger. A thermal transfer fluid is heated by a heat exchanger is communication with a heat source. The heated fluid is circulated through the heat exchanger to heat the contaminated water. A steam engine is coupled to a generator, the steam engine receives the steam from the heat exchanger to drive the generator to provide power for the system. Steam exhausted from the steam engine is supplied to supplemental heat loads and then condensed in a modular condensing system. The collected contaminants are directed to an evaporation device to remove residual liquid.

Abstract: An apparatus provides for the non-destructive testing of samples. The samples can in this respect also be formed from critical materials which change their properties during manufacture, for example on a hardening or solidification. In an apparatus in accordance with the invention, at least one ultrasonic pressure wave transducer is arranged at a forward cell. The forward cell is filled with a liquid and is placed with an open side at one side onto a surface (A) of a conversion prism, in the form of a solid body, so that the liquid and the surface (A) are in touching contact. The conversion prism is placed with a further surface (B) onto a surface of a sample to be tested. At least one ultrasonic pressure wave transducer can be positioned or is positioned at the forward cell at at least two positions (T1, T2) so that the positions are arranged at an equal spacing from the center of the surface (A) of the conversion prism, said surface being placed onto the sample.

Abstract: A system reclaiming contaminated water includes a heat exchanger that receives the contaminated water and converts at least a portion of the contaminated water into steam and collects at least a portion of the contaminants within the heat exchanger. A thermal transfer fluid is heated by a solar concentrator during daytime and by a biofuel combustion device during nighttime. The heated fluid is circulated through the heat exchanger to heat the contaminated water. A steam engine is coupled to a generator, the steam engine receives the steam from the heat exchanger to drive the generator to provide power for the system. Steam exhausted from the steam engine is supplied to supplemental heat loads. The collected contaminants are directed to an evaporation device to remove residual liquid.
