Abstract: L'invention concerne un procédé de catalyse de réactions complexes de grandes molécules, notamment de réactions catalysées par enzymes, où des réactions consécutives ou secondaires indésirables interviennent, à l'aide d'enzymes liées à un support polymère. Selon ce procédé, les réactions consécutives ou secondaires indésirables sont évitées dans une large mesure, grâce à la sélection d'un matériau support sans porosité ou presque. L'invention concerne en particulier un procédé permettant d'obtenir par voie enzymatique des biomolécules, de préférence des peptides, des protéines, des oligosaccharides ou des polysaccharides, à partir de leurs précurseurs biologiquement non actifs, à l'aide d'enzymes liées à un support polymère. L'invention concerne notamment un procédé de préparation d'insulines ou de leurs analogues à partir des précurseurs correspondants, à l'aide d'enzymes liées à un support polymère. Ce procédé permet d'obtenir, grâce au choix d'un support sans porosité ou presque, ce qui évite dans une large mesure la formation de réactions consécutives ou de réactions secondaires, la formation sélective de biomolécules, notamment d'insuline ou d'analogues d'insuline et de substances apparentées, aptes au clivage pour former des insulines ou leurs analogues.

Abstract: A method and apparatus for mounting auxiliary eyeglasses (10) on conventional eyeglasses (12) in which magnets are attached to appendages (18) on the auxiliary eyeglasses mating with magnets mounted on the temple extensions (22) of conventional eyeglasses. The magnets (26) on the auxiliary eyeglasses are mounted in sockets (28) formed on the appendages (18) of the auxiliary eyeglasses such that their maximum magnetic force is oriented vertically or parallel to the plane of the conventional eyeglass frame.  The appendages (18) on the auxiliary eyeglass frame (16) fit beneath the temple extensions (22) on the conventional eyeglass frame (20) to hold the auxiliary frames in place solely by the magnetic attractive force. The orientation of the magnets is such that the maximum magnetic force resits any downward movement of the auxiliary eyeglasses (10) on the conventional eyeglasses (12) when installed. In a modification of the embodiment, the magnets mounted on the conventional eyeglasses are recessed in sockets formed on the temple extensions while the magnets mounted on the appendages extend out of the sockets. The extended magnets fit into the recesses in the conventional eyeglass sockets automatically aligning and securing the auxiliary eyeglasses on the conventional eyeglasses. Another embodiment is comprised of a universal adapter (80) in which a magnet is mounted in a cylindrical sockets (82) and has a tongue (84) with a hole (86) for mounting on conventional eyeglasses with existing hardware.

Abstract: In a switch with multiple physical links to a destination, data is forwarded to the destination by distributing received data across the physical links. A  flow hash is selected for the received data's data flow dependent on a destination address and source address included in the received data. The flow hash selects one of the physical links to the destination for a data flow but potentially a different physical link for a different data flow, thereby fowarding the received data by distributing the received data across the physical links while maintaining frame ordering within a data flow.

Abstract: A method and apparatus for reducing crop losses during slab and ingot rollin g concerns the formation of a slab ingot having a specially configured or shap ed butt end and optionally a head end as well. A special shape is formed by machining, forging or preferably by casting. The special shape at the butt e nd is imparted during casting by a specially shaped bottom block or starter block. The special shape of the bottom block is imparted to the cast ingot butt end. The specially shaped butt end of a slab shaped ingot is generally rectangular in shape and has longitudinally outwardly extending, enlarged portions (24), which slope downwardly toward a depressed central valley regi on (26). The lateral sides of the enlarged end portions and the depressed valle y region carry transversely extending, tapered or curved edges. A similar shap e may be imparted to the head end of the ingot at the conclusion of a casting run through the use of a specially shaped hot top mold or by way of machinin g or forging the cast head end. During subsequent hot rolling in a reversing roughing mill, the specially shaped slab ingot minimizes the formation of overlap and tongue so as to improve material recovery by reducing end crop losses and to increase rolling mill efficiency by increasing metal throughpu t in the mill.

Abstract: A display for viewing images in a preferred direction (26). Parallel, macroscopically planar, structured surface, non-light absorptive light deflecting and reflecting portions are longitudinally symmetrical in mutually perpendicular directions (24, 20) which are perpendicular to direction (26). A  liquid (28) containing members (34) contacts the reflecting portion. A  controller (56) applies an electromagnetic force to selectively move the members into an evanescent wave region adjacent the reflecting portion, frustrating TIR at selected points on the reflecting portion. The deflecting portion's structured surfaces deflect (42) light rays incident (40) in direction (26) toward the reflecting portion by imparting to the rays a directional component in the reflecting portion's direction of longitudinal symmetry. The reflecting portion's structured surfaces totally internally reflect (44, 48) the deflected rays toward the deflecting portion wherever TIR  is not frustrated. The deflecting portion's structured surfaces deflect (50) the TIR'd rays, cancelling the directional component, such that the deflected TIR'd rays emerge (51) substantially parallel to direction (26).
