Title: Mercury electrode for anodic and cathodic voltametry - using a substrate of pyrolytic graphite
Inventor: BEDNARSKI THEODORE MARK
IPC: G01N27/34
Filed: 1974-10-30
Abstract: The material consists of a substrate coated with a thin, continuous, coherent layer of Hg where at least that part of the substrate carrying the Hg is pyrolytic graphite to which 9 x 10-12 to 1.3 x 10-9 gram atoms Hg/cm2 are chemically bonded to the outer C-atoms; the crystal grating plane of the graphite is pref. parallel with the coated surface. Before forming the Hg layer using Hg++ions, hydrogen atoms are deposited on the surface of the graphite either by heating in H2 or abrading the surface in a hydrocarbon liq. with 5-20 C-atoms in the absence of air. The soln. used to deposit Hg is mercury perchlorate dissolved in a mixt. of trifluoroacetic acid (I) and trifluoroacetic -anhydride (II) and Hg is then deposited electrolytically on top of the chemically deposited layer to give an Hg thickness of 0.1-2 mu. An electrode for determn. of trace metals, e.g. Pb or Cd down to concns.

Title: Tripping circuit for an asynchronously running synchronous machine - using induced slip frequency currents as trip signal switches off machine when overload occurs
Inventor: WOYDT GUENTER DIPL ING
IPC: H02H7/08
Filed: 1974-10-30
Abstract: The circuit is particularly applicable to brushless synchronous machines which, due to some fault, may be caused to slip either with or without excitation. The relay circuit tests the stator current for slip frequency modulations, and if these are present it separates out the slip frequency component and uses it as a trip signal for the machine. At the same time it may also trip the field circuit of the brushless exciter. By using slip frequency there is no reliance on measuring inductive wattless power to derive a trip signal as in existing installations, because with some excitation applied the wattless component may be swinging between inductive and capacitative thus making reliable tripping uncertain.

Title: Ozone generator with coaxial tubular electrodes - has gas flowing transversely through annular spaces and additional liq.-cooled chambers
Inventor: DMITRIEV ANDREJ VLADIMIROVITSC
IPC: C01B13/11
Filed: 1976-06-29
Abstract: Ozone generator comprises a housing in which tubular ozone-generating elements are mounted parallel to each other. Each element comprises outer and inner, coaxial tubes sepd. by a dielectric barrier and forming a constant annular space between them. The tubes are liquid-cooled and the gas flows through the constant width annular space and is subject to an electrical discharge to generate ozone. Between adjacent ozone-generating elements there are gas-cooling chamberrs communicating with the annular spaces in the elements, so that a series path for the gas is formed from inlet to outlet and thus transversely to the tubular ozone-producing elements themselves. The improved cooling of the gas during ozonisation enables its temp. to be kept down, thus enabling the intensity of ozone prodn. to be increased without loss of efficiency.
