  • Patent number: 6154683
    Abstract: Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.
    Type: Grant
    Filed: June 3, 1998
    Date of Patent: November 28, 2000

  • Patent number: 5936074
    Abstract: The present invention is directed to deacyl teicoplanin, and to a process for preparing deacyl teicoplanin by reacting teicoplanin with ECB deacylase. Deacyl teicoplanin can be alkylated to produce compounds useful for their antibacterial activity.

  • Patent number: 5919756
    Abstract: The present invention is directed to amides of antibiotic A82846B (also known as chloroorienticin A), and of N.sup.4 -derivatives of A82846B. The present amide compounds are useful as antibacterials, especially for the control of gram positive bacteria; the compounds are particularly useful for the control of resistant bacterial strains, such as vancomycin-resistant-enterococci ("VRE").

  • Patent number: 5820017
    Abstract: A bag-in-the-box container comprises a box folded from flexible sheet material and having side walls, a bottom closure and a top closure. An integral pouring spout formation is formed between one of the side walls and the top closure. The pouring spout formation comprises a lower projecting wall which folds along a lower fold line with respect to the side wall and an upper wall arrangement including a rear portion which forms part of the top closure and a front projecting wing portion which is delineated from the rear portion by means of at least one upper fold line. The upper wall is preformed to bow upwardly above the plane of the top closure and the lower projecting wall so as to define a spout passage in conjunction with the lower projecting wall when the pouring spout formation is in the raised pouring position and to collapse towards the lower projecting wall when the pouring spout is folded downwardly into a lowered position against the side wall.

  • Patent number: 5675818
    Abstract: A Database Management System having a Collation Engine with improved methods for sorting information with National Language Support (NLS) is described. The Collation Engine includes an improved method for comparing text strings with a culturally predictable result. In an exemplary embodiment, the Collation Engine includes a Collation Table storing primary, secondary, and tertiary weightings. The weightings are employed, in a method of the present invention, for accounting for locale-dependent factors or rules other than those taken into account by conventional primary and secondary weightings. Additional rules include, for instance, local-specific sorting rules specifying that the case of a character be taken into consideration, or that the expansion of an expanding character (e.g., "" which expands to "AE") be taken into consideration.

  • Patent number: 4059673
    Abstract: Removal of iron from aluminous material such as bauxite is effected by treatment with a gas mixture comprising sulphur dioxide and carbon monoxide in a first step, followed by chlorination in a second step whereby ferric chloride is produced and removed by volatilization. Aluminium chloride of low iron content may be obtained from the purified aluminous material by chlorination.
