    Description / Table of Contents: Investigations on the Catalysis of Ammonia Synthesis and Nitrogen Isotope Exchange by Lamellar Compounds of Graphite with Iron, Ruthenium, and OsmiumThe catalytic activity of transition metal potassium-graphite lamellar compounds for the synthesis of ammonia from the elements and the catalysis of the equilibration by isotope exchange of the isotopic nitrogen molecules are shown to correlate. Connections between the state of metal in the catalyst exist with iron as metal which is shown by Mössbauer spectroscopy and the catalytic activity in relation to the potassium content.
    Notes: Die katalytische Aktivität von Übergangsmetall-Kalium-Graphitverbindungen bei der Synthese von Ammoniak aus den Elementen und bei der Einstellung des Isotopenaustauschgleichgewichts der isotopen Stickstoffmolekeln korrelieren miteinander. Im Falle von Eisen als Metall sind Beziehungen zwischen dem durch Mößbauer-Spektroskopie ermittelten Zustand des Metalls im Katalysator und der katalytischen Aktivität in Abhängigkeit vom Kaliumgehalt erkennbar.

    Description / Table of Contents: Synthesis and Molecular Structure of a Metal Cluster with Cubane Structure, [η5-C5H5Mo(CO)3HgMo]4(4)The compound [η5-C5H5Mo(CO)3HgMo]4 has been isolated as an additional product of the reaction between [η5-C5H5Mo(CO)3]2, 2-butenyl chloride, and sodium amalgam. The X-ray structure (R = 0·050) analysis of this novel species revealed that the compound has a slightly distorted cubane structure, for the first time the cubane unit being built up by two different metal atoms (Mo and Hg).

Die Röntgenstrukturanalyse dieser neuartigen Spezies zeigt eine leicht verzerrte Cubanstruktur, bei der das Cubangerüst erstmals aus zwei verschiedenen Metallatomen (Mo und Hg) aufgebaut ist. Der R-Wert beträgt 0·050.

    Remote sensing using solid-state array technology (1979)
    In:  Other Sources
    Details
    Publication Date: 2011-08-17
    Description: The paper describes the design features and capabilities of a remote sensor that uses solid-state linear arrays and operates in a 'pushbroom' scan mode to provide the required performance. Pushbroom scanning is a term describing the technique of using the forward motion of a satellite platform to sweep a linear array of detectors oriented perpendicular to the ground track across a scene being imaged. One array is typically used for each spectral channel. Satellite motion provides one direction of scan and electronic sampling of the detectors in the crosstrack dimension provides the orthogonal scan component to form an image. The detector array is sampled at the appropriate rate so that contiguous lines are produced. The performance of a pushbroom system is discussed relative to radiometric sensitivity, detector array geometric fidelity, and radiometric correction. System advantages are precision geometric positioning of the detectors, very high sensitivity and favorable SNR, low power consumption, and no moving optics.

    Readout electrode assembly for measuring biological impedance (1976)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: The invention comprises of a pair of readout ring electrodes which are used in conjunction with apparatus for measuring the electrical impedance between different points in the body of a living animal to determine the amount of blood flow therebetween. The readout electrodes have independently adjustable diameters to permit attachment around different parts of the body between which it is desired to measure electric impedance. The axial spacing between the electrodes is adjusted by a pair of rods which have a first pair of ends fixedly attached to one electrode and a second pair of ends slidably attached to the other electrode. Indicia are provided on the outer surface of the ring electrodes and on the surface of the rods to permit measurement of the circumference and spacing between the ring electrodes.
