    Abstract: Oriented silicon steel is heated in a slab furnace at temperatures above 1260.degree. C. prior to hot rolling. The slab surfaces in the furnace are exposed to molten slag, variable atmosphere conditions and refractory interaction from the hearth. The slab surface prior to hot rolling has a major importance for cold rolling and the quality of the glass film.A rapid oxidation treatement of the slab just prior to the scale breaker or first rolling stand corrects a silicon-free iron layer condition which causes streaks in the glass film. The oxidation treatment blows gas having at least 30% oxygen for a sufficient time and velocity to provide a surface which will develop a continuous fayalite layer in subsequent processing and provide for the formation of a continuous glass film.

    Abstract: The present invention relates to a process for producing permanent domain refinement continuously and at very high line speeds in grain oriented electrical steel having an aluminum nitride inhibitor system. After the final high temperature anneal, the glass film and insulative coating on the surface is removed in narrow bands (grooves or rows of spots). The steel is electroetched to increase the depth of the bands, coated with aluminum by electrophoresis and given a stress relief anneal to bond the aluminum coating to the base metal by diffusion. A localized stress field is induced during cooling which causes domain refinement due to the differential thermal contraction between the aluminum and the base metal.

    Abstract: An X-ray tube comprises an anode assembly having an associated anode and a cathode assembly for providing a focused electron beam directed to the anode. An anode target, associated with the anode assembly, accelerates the electron beam and produces X-rays upon electron impact with the anode target. Off-focal radiation tends to be most intensely emitted by the top surface of the target. In conventional X-ray tubes, the off-focal radiation as seen by the detector encompasses almost the entire top surface of the target assembly. In accordance with the present invention, the anode target comprises a cut-out top surface for reducing off-focal radiation, by blocking the off-focal radiation from the top surface from reaching the detector. Blocking the radiation produced at the top surface becomes more important as the ratio of the track area visible at the detector decreases with respect to the top surface area.

    Abstract: A method of bonding a metallic target layer and a graphite disk to provide a composite rotating X-ray tube target wherein a high vapor pressure metal is placed between the target layer and the graphite disk and the vapor pressure of the joint is controlled. The vapor pressure is controlled by limiting the thickness of the joint and thereby causing the metallic character of the braze joint in this region to be altered. In a preferred manner, this is effected by interfitting projecting and recessed portions in the graphite disk and metallic target layer. The preferred high vapor pressure metal is titanium. A composite X-ray tube target is produced having a high remelt temperature and thus capable of being employed in X-ray tubes having more aggressive protocols.

    Abstract: Permanent domain refinement of grain oriented electrical steel strip is obtained in a high speed two-stage process. The process removes the glass in narrow regions which just expose the base metal. An electrolytic etch is then used to deepen the region into the base metal and minimize damage to the remaining glass film. Control of acid concentration and temperature in the electrolytic bath allows a greater increase in productivity. A further feature of the process is the use of permeability measurements to optimize the depth of the etched regions. The improved core loss produced by the process will survive a stress relief anneal.
