    Description / Table of Contents: Zusammenfassung 1. Bericht über 4 Fälle mit traumatischen Aneurysmen der A. carotis interna und Übersicht über die zugehörige Literatur. Bei 3 Fällen war es zu massiven Blutungen in den Nasen-Rachen-Baum gekommen, bedingt durch eine Ruptur der Aneurysmen in die Nasennebenhöhlen. Bei dem 4. Fall, bei dem keine Blutung in den Nasen-Rachen-Raum entstand, war gleichzeitig eine Kurzschlußverbindung zwischen Karotis und Sinus cavernosus entstanden. 2. Schädelbasisfraktur, einseitige Blindheit und rezidivierende schwere Blutungen in den Nasen-Rachen-Raum einige Zeit nach dem Trauma müssen immer an ein traumatisches Aneurysma der A. carotis interna im Bereiche der Schädelbasis denken lassen. 3. Die Möglichkeiten chirurgischer Therapie wurden kurz diskutiert.
    Abstract: Résumé 1. 4 cas d'anévrysmes traumatiques de l'artère carotide interne sont rapportés. Chez 3 malades, rupture de l'anévrysme dans les sinus paranasaux avec saignement du nez extrêmement sévère. Pas dépistaxis dans la quatrième cas, mais formation d'dune fistule entre l'artère carotide interne et le sinus caverneux, suivie par l'angiographie pendant plusieurs mois. Discussion de la littérature. 2. Les symptômes d'un anevrysme traumatique de l'artère carotide interne sont les suivants: fracture de la base du crâne, amaurose unilatérale, sévère épistaxis tardif et récidivant. 3. Discussion brève du traitement chirurgical.
    Notes: Summary 1. Four cases of traumatic aneurysm of the internal carotid artery are presented and the available literature is reviewed. In 3 cases, a massive epistaxis occurred following rupture of the aneurysm into the paranasal sinuses. In the remaining case, no epistaxis occurred, but the caroticocavernous fistula was associated with the aneurysm and both were studied by repeated angiograms over several months. 2. Fracture of the base of the skull, monocular blindness and recurrent severe epistaxis of late onset strongly suggest that a traumatic aneurysm of the internal carotid artery at the base of the skull is present. 3. Surgical treatment has been briefly discussed.

    Notes: A new high-permeability, grain-oriented 3% silicon steel sheet of 7-mil or 0.18-mm gauge was developed by solving such problems as increasing difficulty in secondary recrystallization with decreasing sheet thickness. Typical magnetic properties of the sheet are an induction (B10) of 1.93 T at a magnetizing force of 1000 A/M and a core loss (W13/60) of 0.245 W/lb at a frequency of 60 Hz and at an induction of 1.3 T. The core loss can be reduced further to 0.220 W/lb if the sheet is treated by an artificial permanent domain control technique. When the price and other properties are also taken into account, this very low core loss seems to favor the 7-mil silicon steel sheet over amorphous metals.

    Notes: The present paper is concerned with the development of low-loss grain-oriented silicon steel, and especially with the magnetic properties and domain structures in domain refined grain-oriented silicon steel. The effects of locally induced stress and slight magnetic flux emergence have been examined as possible nucleation centers for effective domain walls which contribute to magnetization. The fundamental phenomena and their origins have been discussed on the bases of experimental facts. It was concluded that these domain refining effects were based upon interactions between subdomains having transverse magnetization, which originate from magnetic free poles and/or internal stress, and tensile stress in silicon steel with orientation near (110)[001]. The features of magnetic properties and domain structures of domain refined grain-oriented silicon steel both for stack and wound cores are described. Finally, a new technique for raising the degree of (110)(001) orientation is introduced, and the approach to minimum loss in grain-oriented silicon steel is discussed.
