Abstract: ABSTRACT OF THE DICLOSURE         The present invention relates to a proce3s for the preparation of 7-acvlamido-7-alkoxycephalosporins which comprises reacting a 7-(5-amino-5-carboxyvaleramido)-7-methoxycephalosporin with amino and acid groups protected, with PCl5 or other agent capable of forming an imino halide; thereafter reacting the resulting imino halide under essentially non-aqueous conditions with a primary lower-alkanol of C1-C4 or with methan-d3-ol, to yield a nucleus bearing a 7-alkoxv group derived from the primary lower-alkanol or methan-d3-ol.  In situ acylation of the nucleus affords 7-acylamido-7-alkoxycephalosporins in good yield.  These products can he deesterified to yield the corresponding acids, which exhihit antibacterial activity.

Abstract: ABSTRACT OF THE INVENTION          Filters are coupled to receive an uncorrected composite color television signal, which signal has been sub-jected to recording and reproducing operations and processed to have incoherent luminance and chrominance compo-nents, with the chrominance component color corrected.  The filters separate the composite signal into its luminance and chrominance components.  The chrominance component is coupled to a decoder to prepare it for subsequent encoding relative to a chrominance subcarrier reference signal that is coherent with the luminance component.  The chrominance subcarrier reference signal is provided by a generator that is frequency and phase adjusted relative to the luminance component.  A following encoder receives the decoded chrominance component and reference signal.  The encoder responsively operates to provide a newly encoded chrominance component stabilized to the reference signal. This causes the newly encoded chrominance component to be coher-ent with the luminance component.  Both components are then com-bined and coupled to a conventional line-to-line time-base cor-rector for correcting any time-base errors -that are present in the combined components.                             -2a-

Abstract: ABSTRACT OF THE DISCLOSURE           An improved mechanical cork puller wherein the pivot holes of the lever arms receive and pivot about one or more ribs formed on the inner surfaces of the opposed pairs of support ears, resulting in no visible sign of a pivot support on the outer surfaces of the support ears.  The support ears have an inwardly diverging taper providing free meshing movement between the toothed sectors of the lever arms and the cork puller shaft. To manufacture, elongated rib members are initially die-cast on the inner surfaces of the support ears and thereafter cut away to the desired length to form the pivot support for the lever arms. As cast, the inner surfaces of the support ears diverge outwardly and thereafter the outer ends of the support ears are bent toward each other so that the inner surfaces thereof diverge inwardly. The lever arms are thereafter assembled by merely force fitting them into place between the support ears.

A cylindrical sleeve, having a first end and a second end, is mounted by means of a bellows in a cylindrical shell having a first end and a second end each corresponding with that of the sleeve.  The first end converge to form a convection input passage therebetween, the second ends diverge to form a radiant zone therebetween.  Hot gas passes between the shell and the sleeve through the radiant zone and then the convection input zone, the process stream passes through the inner flow space.  A baffle is mounted within the sleeve in its first end to channel the process stream into a convection output passage boardered inwardly by the baffle and outwardly by the sleeve. Extended surface projects from the sleeve into the convection input zone and additional extended surface projects from the sleeve into the convection output passage.

Abstract: L' invention a pour objet un procédé de régénération de zinc à partir d'une solution alcaline de zincate.  A cet effet on met la solution en contact avec deux électrodes sous tension de sorte que du zinc se dépose sur l'électrode négative et que de l'oxygène se dégage sur l'électrode positive, cette solution étant acheminée selon une vitesse suffisante pour que le zinc se dépose puis soit dissocié de l'électrode.  Une variante consiste dans un premier temps à acheminer la solution selon une vitesse faible ou nulle pour laisser déposer le zinc, puis selon une vitesse plus élevée pour arracher les particules de zinc.  L'électrode négative réalisée de préférence en magnésium peut être un barreau cylindrique ou notamment comporter des excroissances.  L'invention est mise en oeuvre dans les véhicules électriques.

Abstract: CONFIGURATION AND CONTROL UNIT FOR A HETEROGENEOUS  MULTI-SYSTEM                   Abstract Of The Disclosure Describes a configuration and control unit (CACU) for a heterogeneous multi-system containing processors which may be of different types, channels, one or more channel crossbar switches which may be of different sizes, various I/O channel switches, I/O control units and I/O devices.          The CACU is the focal point in the multi-system for confi-guration control over all of these system heterogeneous components.  The CACU enables the configuration of any switchable part of the entire multi-system to be established and changed at any time due to new processing requirements or failure of part or all of the system.    The CACU contains a parallel wire line (PWL) adapter for providing DC switching control over components connected through channel crossbar switches and/or channel I/O switches.     The CACU also has a time multiplexed (TM) adapter connected via serial time multiplexed lines (TML's) to remote modem adapters (RM's) with devices controlled by or switched by the CACU.  A TML can provide serial pulse control switching for components connected to channel crossbar and/or channel I/O switches, which transfer data directly from the processor channels whereby the data bypasses the CACU.  A TML can also provide serial pulse data to other devices which have their data passed through and switched by the CACU for switchable communication with any processor.  A persistent storage unit is providable in the PWL adapter and TM adapter for perma-nently storing the current configuration of PWL and TML connected units.  Upon failure of any one or more units connected to the PWL adapter or TM adapter, the settings in the persistent storage devices can recover the operating configuration of devices in the multi-system.
