    Description: Recent studies of the continuous spectrum of Herbig-Haro (HH) objects at optical and near-infrared wavelengths and the observation of continuous radiation in the ultraviolet have shown an unexpectedly steep increase of the flux toward shorter wavelengths. The present investigation provides the results of ultraviolet observations of HH 2. The obtained data are compared with the HH 1 data. It is found that HH 2 has an ultraviolet continuous and emission-line spectrum which is similar to that of HH 1. The UV line spectrum of HH 2H indicates an even somewhat larger ionization than does the HH 1 spectrum. As in HH1, the UV emission-line spectrum shows a much higher degree of ionization than that derived from the optical spectrum. Consequently, the same difficulty arises as in the case of HH 1. The complete UV plus optical spectrum cannot be explained by a single plane-parallel shock-wave model.

    Notes: Application of Magnetic Microparticles in Chemical Engineering Technology In chemical engineering technology microparticles are used in a diversity of fields. Particles with essential chemical characteristics and additional magnetic properties open new opportunities for developing novel processes in many areas. Separation processes such as adsorption and chromatography as well as reactions with catalysts are especially interesting applications. A high specific surface is advantageous for most of these unit operations. Because of the small size of the particles used their handling is not trivial. The magnetically stabilized fluidized bed (MSFB) is a promising example of a magnetically assisted process. This technology permits design of new processes whose favorable operations conditions lie outside the range of conventional operation. Common to all applications is that the magnetic properties of the particles provide a new free and adjustable parameter for managing the process.

    Notes: Zur Dosierung gefährlicher, aggressiver und verschleißend wirkender Medien werden immer häufiger stopfbuchslose Dosierpumpen in Faltenbalg- und Membranausführung angewendet. Hierbei haben die Pumpen mit mechanischem Verdrängerantrieb den Vorzug einfacher Bedienung und Wartung, jedoch sind Förderströme, Förderdrücke und Temperaturen begrenzt. Die komplizierteren und teureren Ausführungen mit hydraulischem Verdrängerantrieb gestatten auch höhere Drücke; der Verdränger wird günstiger beansprucht, und das Hubvolumen ist stets genau definiert. Auf Grund von Untersuchungsergebnissen, Auslegungs- und Anwendungserfahrungen werden Anwendungsbereich, Saugvermögen, Strahlenresistenz, Förderverhalten, Dosiergenauigkeit, Lebensdauer und Dichtheit der stopfbuchslosen Dosierpumpen erörtert. Für die Planung dient ein Überblick zur Anwendung stopfbuchsloser Dosierpumpen.
