Abstract: An apparatus for remediating a contaminated fluent material, such as a gas, utilizes a pulsed corona discharge. The apparatus includes a reactor section and a power supply section. The reactor section has a plurality of first electrodes electrically interconnected to a header plate and a plurality of second electrodes concentrically disposed about each first electrode and electrically interconnected to a reactor plate. The electrical contact between the header plate and the power supply is by a compression spring. When fluent material is flowing within channels defined by the second electrodes and a high voltage pulse is applied to the header plate, a stream of high energy electrons flows between the first electrodes and the second electrodes forming corona discharges effective to destroy polluting compounds contained in the contaminated fluent material.

Abstract: A method of treatment by ultrasound comprises providing a first, ultrasound field intensity-to-voltage transducer sized for insertion into the vicinity of a treatment site and a second ultrasound treatment transducer. The free field intensities created by the second transducer in response to various second transducer exciting signal levels are determined. The first transducer outputs in the free field in response to various second transducer exciting signal levels are also determined. The first transducer is inserted into the vicinity of the treatment site, and the second transducer is positioned to create an ultrasound field at the treatment site. The distance from the second transducer to the first transducer is determined. An exciting signal is applied to the second transducer. The output of the first transducer is determined.

Abstract: The invention refers to a thermoelectric generator unit comprising a plurality of thermoelectric elements (1) of alternately p and n character and electrically series connected by means of metal connector members (2), the elements having essentially cylindrical shape.

Abstract: A method of electrolytically producing an organic compound is disclosed, wherein an organic solvent and an electrolyte which is dissolved therein is placed in an anodic or cathodic chamber. The chambers are separated by a semi-permeable membrane. At least one of the electrodes is a gas permeable electrode which includes a reaction layer joined together with the gas permeable layer. The reaction layer is composed of minute hydrophilic and hydrophobic carbon black, and the gas permeable layer is composed of minute hydrophobic carbon black.

Abstract: An ion-selective electrode having an electrically insulating substrate with a substantially planar first surface, and having a non-metallic conductor for sensing a potential affixed to the first surface beneath an ion-sensitive membrane. An electrically insulating layer covers at least a portion of the non-metallic conductor and means for making electrical contact with the non-metallic conductor.
