Abstract: Ausschnittsvergrößerungen von Fernsehbildern lassen sich durch Dehnung des Bildes gleichzeitig in vertikaler und horizontaler Richtung erzielen. Im einfachsten Fall kann dies durch Erhöhung der Ablenkamplituden erfolgen. Da die Horizontalablenkung den größten Teil der in einem Bildwiedergabegerät umgesetzten Energie benötigt und leistungsstarke Bauelemente verlangt, würde eine Erhöhung der Ablenkamplituden die Energieaufnahme nochmals steigern und auf die Forderungen an die Leistungsfähigkeit verwendeten Bauelemente weiter erhöhen. Dies ist unerwünscht. Die Erfindung schafft Abhilfe, indem die in horizontaler Richtung aufeinanderfolgenden Bildinformation einer gerade übertragenen oder wiedergegebenen Bildzeile gespeichert werden und anschließend aufeinanderfolgende Bildinformationen eines Ausschnitts der Bildzeile über die gesamte Zeilenbreite gedehnt dargestellt werden. Die Erfindung ist als wählbare Umsatzfunktion bei Fernsehempfängern einsetzbar, um z.B. bei Wiedergabe von Spielfilmen mit einem anderen Format eine Umsetzung auf die volle Bildschirmhöhe zu erzielen ohne dabei Verzerrungen der Geometrie hinnehmen zu müssen.

Abstract: The strong magnetic field generator has concentric conductor cylinders (4a-6a, 4b-6b), each of which has a longitudinal slit (2b) so as to have an open sidewall. Exciting coils (7a-9a, 7b-9b) are mounted on the cylinders (4a-6a, 4b-6b) to induce an eddy current in each cylinder in a circumferential direction. A conductor plate (1) with a radial slit (2a) extending from a central hole (3) to the periphery is connected to the cylinders (4a-6a. 4b-6b), the central hole (3) being at the centre of the cylinders and the longitudinal slits (2b) of all the cylinders being aligned with each other along the radial slit (2a). Thus, the path of the eddy current in each cylinder is closed through sidewall portions of the radial slit (2a) and the central hole (3), and the eddy currents of all the cylinders are superposed at the sidewall portion of the central hole (3) for generating a very strong magnetic field there.

Abstract: Process for gas phase polymerisation of olefins using a highly active catalyst in a fluidized bed reactor (1), comprising a reactor body (2) partially occupied by the fluidized bed and surmounted by a disengagement chamber (3). The gas mixture withdrawn from the disengagement chamber (3) is fed to a dust separator (6) e.g. a cyclone, to separate the fine particles entrained by the gas. The gas is cooled, compressed and recycled to the base of the reactor. The particles are withdrawn from the dust separator (6) by a mixing device (8) which mixes the particles with a carrier gas. The carrier gas and particles are recycled to the reactor where they are introduced into the reactor body (2) through an opening in the side wall thereof at a position above the fluidized bed, but below the disengagement chamber (3). The velocity of the particles introduced into the reactor is insufficient to cause them to be blown directly into the bed.

Abstract: Anthralin analogues containing a thio-substituent, especially in one or more of the positions 2-, 7- and 10- of the anthralin ring. They may be made by reacting an anthralin derivative (e.g. 10-bromoanthralin) with a thiol or a compound containing a group convertible to a thio-group. Alternatively, a 1,8-dihydroxy anthraquinone containing a thio-substituent may be reduced. Reactive intermediates may be made by introducing one or more nuclear allylic groups into a 1,8-dihydroxy anthraquinone and then converting them into a reactive form, e.g. by epoxidation or halide addition. The intermediate can then reduced to the oxidation state corresponding to anthralin. 
     Additional products having the 10-carbon atom of the anthralin ring as part of a heterocyclic ring, may be made by anthralins containing various substitutes thioalkyl groups as the 10-substituent. 
     The compounds are useful for treatment of psoriasis, and may be formulated in the conventional vehicles for topical application, for example petrolatum.

Abstract: DNA encoding the gene for the synthetase enzyme capable of generating δ(L-α-aminoadipyl)-L- cysteinyl-D-valine (ACV) from its constituent amino acids was obtained from several penicillin and cephalosporin producing organisms, e.g.  Penicillium chrysogenum  and a  Flavobacterium  species. The DNA was used to prepare recombinant vectors comprising the ACV synthetase gene and hosts transformed with such vectors. 
     The ACV synthetase gene can form part of a gene cluster comprising other genes involved in β-lactam biosynthesis and the production of penicillin by expression of the entire biosynthetic gene cluster for the synthesis of penicillin from primary amino acids is described. Suitable hosts in which expression can take place include heterologous hosts which are naturally non-producers of penicillin.

At a specific intensity of these light pulses, the evaluation device operates a switching device (3, 4) which interrupts the current supply to the gas suppressor. Since an arc, occurring in the event of excess voltage, no longer has to be quenched by means of a melting fuse, the power supply down-time is reduced to a minimum. <IMAGE>

Abstract: In a method of depositing a tungsten film on a gate oxide by means of laser CVD, using WF₆ and H₂ as raw material gases, the H₂/WF₆ flow ratio lies within the range 10 - 100, and the volumetric flow rate of the WF₆, whlch ls defined as the ratio of the flow rate of WF₆ to the total pressure, lies within the range 0.04 - 0.01 sccm/Pa, so that the supply of WF₆ determines the deposition rate of the W film, whereby a low stress W film is obtained. Accordingly, peeling of the W film at the interface with the SiO₂ film and cracks can be avoided.

Abstract: An apparatus for monitoring quality of electrical welding processes on bodies (10) for producing cans is described. Welding-parameter values (Fi) which have been measured on a number of bodies (10) found to be acceptable are statistically analysed in an analysing device (22). For this purpose, an average welding-parameter profile is determined. Then a reject limit-value band (Fg+/-) enveloping the average welding-parameter profile is determined from the average values and the product of the standard deviation of the welding- parameter values (Fi), assumed to be normally distributed, and at least one sensitivity factor. A permissible number of mistaken rejects per one million welding spots are selected as a criterion for the sensitivity factor so that, for example in the case of 100 welding spots on a body (10) of a medium-sized can, every ten-thousandth body on average is inadvertently rejected. For bodies (10) produced subsequent to the "learning phase", a comparator (26) establishes whether a welding-parameter profile measured for these bodies (10) lies within the reject limit-value band (Fg+/-). This quality-monitoring apparatus, working according to statistical methods, is sensitive and accurate, since a fixed value is not simply selected for the width of the reject limit-value band. <IMAGE>
