    Notes: Abstract During the last 4 years we observed four cases of neonatal rickets. The mothers of the infants suffered from osteomalacia for 1–3 years prior to its diagnosis shortly after the birth of their children. All four infants were born with craniotabes, and one infant had, in addition, a radial fracture. The diagnoses were confirmed by radiological and laboratory tests which revealed a rarefied bone structure, decreased serum 25-hydroxy-vitamin D and increased alkaline phosphatase levels in all patients. The disorder regressed under low-dose vitamin D3 therapy. As osteomalacia seems to be predominant in oriental women living in Berlin, it is necessary to consider vitamin D deficiency when clinical symptoms of this disease arise and to treat these women at least during pregnancy.

    Notes: Abstract Cockayne's syndrome is a rare familial disorder characterised clinically by premature aging, appearing progressively from the third year on. The radiological manifestations of eight affected children have been studied and summarised. It is concluded that a skeletal survey can provide a roentgenologic pattern suggesting the diagnosis, even when it is inconclusive from the clinical signs during the first years of life. The aetiology of this syndrome is unknown, but the authors postulate the possible role of a defect of thymic hormone which has been found in all their cases.

    Notes: Die Zersetzungsreaktionen des Eisencarbonylwasserstoffs, die im chemischen Verhalten alkalischer Lösungen von Eisenpentacarbonyl in Erscheinung treten, werden in ihrem Mechanismus aufgeklärt und auf die Oxydierbarkeit des Carbonylhydrids, die Disproportionierungen zwischen den Zersetzungsprodukten mit weniger als 5 Mol CO/Fe unter wechselseitigem Kohlcnoxydaustausch, sowie auf die Saurerealitionen der Carbonylverbindungen zurückgeführt. Auf Grund dieser Verhältnisse werden Darstellungsmethoden für Eisentetra- carbonyl beschrieben, die auf der direkten Dehydrierung des Car- bonylwasserstoffs im System Pentacarbonyl-4lkali unter möglichst in milden Bedingungen beruhen.

    Description / Table of Contents: Light turbocharger compressor wheels from aluminium and magnesium investment castingWithin the scope of a team work between Kühnle, Kopp & Kausch AG, Volkswagen AG, Sterling International Technologies Ltd. and the Fraunhofer Institute for Strength of Structures under Operational Conditions LBF compressor wheels of aluminium and magnesium investment casting were developed and tested. Strength and fatigue tests, overspeed and field tests as well as metallographic checks were made in addition to the finite element calculations to optimize the stress under centrifugal force in an appropriate way for the materials involved. The results and the knowledge gathered are to clarify whether magnesium alloys are an appropriate replacement for the proven standard aluminium alloy for turbochargers.
    Notes: Im Rahmen einer Zusammenarbeit zwischen der Kühnle, Kopp & Kausch AG, Volkswagen AG, Sterling International Technologies Ltd. und dem Fraunhofer-Institut für Betriebsfestigkeit LBF wurden Verdichterräder aus Aluminium- und Magnesiurn-Feingußlegierungen entwickelt und untersucht. Festigkeits- und Schwingfe-stigkeitsuntersuchungen, Schleuder- und Feldversuche sowie metallographische Untersuchungen wurden von Finite-Element-Berechnungen begleitet, mit denen Spannungsverteilungen am Bauteil optimiert wurden. Anhand der ermittelten Ergebnisse soll geklärt werden, inwieweit Magnesium-Feingußlegierungen die gegenwärtig für Turbolader-Verdichterräder eingesetzten Aluminium-Feingußlegierungen ersetzen können.
