Abstract: A mixture of ketoxime such as methyl ethyl ketone oxime (MEKO), an inorganic acid such as sulfuric acid and optionally water is fed to an intermediate point of a fractional distillation column. Steam is fed to the base of the column and operating conditions are sufficient to produce the corresponding ketone (e.g. methyl ethyl ketone) or its water azeotrope as the overhead product and the corresponding hydroxyl-ammonium salt (e.g. the sulfate) as the bottoms. Crystallization of the salt from the bottoms leaves a mother liquor which may be recycled to a reboiler from which the steam is generated.

Abstract: Es wird eine Zündkerze vorgeschlagen, die sich dern thermischen Belastungen der Brennkratmaschine weitgehend anpaßt, sodaß bei niedriger Belastung keine Zündaussetzer infolge von Nebenschlüssen entstehen und bei hoher Belastung keine Glühzündungen auftreten. Die Zündkerze enthält im brennraumseitigen Abschnitt ihres Isolierkörpers einen Metallkern, der bei noch kalter Brennkraftmaschine einen Spalt gegenüber dem Isolierkörper bildet und somit eine starke Wärmeableitung verhindert; infolge dieser Gestaltung erreicht der brennraumseitige Endabschnitt des Isolierkörpers schnell eine Temperatur, bei der elektrisch leitfähige Ablagerungen verbrannt (Freibrenntemperatur), damit Nebenschlüsse und demzufolge Zündaussetzer verhindert werden. Bei betriebswarmer Zündkerze dehnt sich der Metallkern jedoch aus, legt sich mit einem Großteil seiner Oberfläche an die Oberfläche des Isolierkörpers, leitet viel Wärme ab und vermeidet damit Glühzündungen; der Metallkern bleibt bei allen Betriebszuständen der Zündkerze in festem Zustand. Durch einen dünnen Boden des Isolierkörpers, durch Verzicht auf eine separate wärmeableitende Mittelelektrode, bzw. durch eine wenig wärmeableitende, separate Mittelelektrode und durch Wahl eines bei niedrigen Temperaturen wenig warmeleitenden Materials für den Isolierkörper ist dieses Verhalten der Zündkerze noch zu optimieren.

Abstract: The invention relates to a process for preparing ABS polymers by continuous mass polymerization wherein an alkenyl aromatic monomer having a diene rubber dissolved therein is charged continuously to a reactor simultaneously with a separate feed-stream of an alkenyl nitrile monomer. The reactor is stirred to maintain, in the reaction mixture contained therein, a substantially uniform composition and operates at a steady state polymer solids level above that at which phase inversion occurs and up to about 70% polymer solids such that the diene rubber added is dispersed as rubber particles having a particle size of about 0.1 to 10 microns. A partially polymerized reaction mixture is continuously removed from the reactor and an ABS polymer is irecovered therefrom. The process is especially useful for preparing ABS polymer having high proportions of both rubber and alkenyl nitrile.

Abstract: In a brushless DC motor having a magnet and multiphase coils, a current is distributed from a DC voltage source to the multiphase coils according to a set of output signals of a position detector detecting the relative position between the magnet and the multiphase coils. Two sets of output transistors, a first output transistors and a second output transistors, are used so as to distribute a current to corresponding some of the multiphase coils. A first distributor activates the first output transistors selectively corresponding to the output signals of said position detector so as to supply the multiphase coils with a current according to a command signal, and a second distributor activates the second output transistors selectively also corresponding to the output signals of the position detector. The second distributor has a voltage drop controller for detecting voltage drops across the first output transistors (or the second output transistors) in each activated period and for controlling output currents of the second output transistors so as to maintain the voltage drops across the first output transistors (or the second output transistors) in each activated period at a predetermined value regardless of the relative position between the magnet and the multiphase coils.

Abstract: A matched filtering method for x-ray image subtraction procedures in which an x-ray contrast medium is injected intravenously. A sequence of pre-contrast x-ray images are made during a period before the medium arrives in a blood vessel that is to be imaged and the sequence is continued through the post-contrast period and in some cases, an after-contrast period. A curve or plot of how projected intensity of the contrast medium varies as a function, h, at times (t) is determined at some prior time based on characteristic patients or, in the alternative, by using the post-contrast image data obtained from the patient presently undergoing examination. In either case a sequence of coefficients or weighting factors are produced that are proportioned to the value of the function h at the time (t) at which the corresponding image in the post-contrast sequence was acquired. By multiplying the coefficients and their time matched images, those images which have more contrast medium intensity get the most weight, which taken in conjunction with some image subtraction steps, results in maximizing contrast medium signal relative to noise and in utilizing all of the contrast medium signal.

Abstract: A heat exchanger according to the present invention has a plurality of heat transfer tubes (10) fastened to upper and lower tube plates (5, 23) provided in a heat exchanger body (3). An upper plenum (24) is formed in the portion of the interior of the heat exchanger body (3) which is above the upper tube plate (23), and a lower plenum (6) in the portion thereof which is below the lower tube plate (5). The upper and lower plenums (24, 6) are communicated with each other via the heat transfer tubes (10). A downwardly-extending tube (16) extending through the upper plenum (24) upper tube plate (23) and used to introduce secondary sodium into the lower plenum (6) extends among the heat transfer tubes (10) to be fastened to the lower tube plate (5) and communicated with the lower plenum (6). The downwardly-extending tube (16) is stretched through the lower plenum in the axial direction thereof to contact at its lower end a bottom surface (34) of the heat exchanger body (3). A plurality of openings (17) are provided in a wall of the portion of the downwardly-extending tube which is in the lower plenum (6). 
     The primary sodium of a high temperature flows into the heat exchanger body from the portion thereof which is below the upper tube plate (23), and flows out of the heat exchanger body from the portion thereof which is above the lower tube plate. The method for supplying the secondary sodium of a low temperature is characterized in that the secondary sodium flows downward through the downwardly-extending tube (16) to be ejected in the horizontal direction from the above-mentioned openings (17) into the lower plenum (6). The secondary sodium ejected into the lower plenum flows in parallel currents therein to enter each of the heat transfer tubes and advance upward. The secondary sodium heated in the heat transfer tubes (10) is ejected into the upper plenum (24).
