  • Patent number: 6007250
    Abstract: An outer ring has a spherically convex outer surface mounted within a bore of a housing such that the outer ring may be misaligned with respect to the axis of the bore. A sensor target is mounted on an inner ring that is rotatable with respect to the outer ring, and a seal is mounted on the outer ring. A sensor is mounted on the seal in proximity to the sensor target, and a flexible electrical conductor is connected to the sensor for transmitting signals from the sensor. A portion of the flexible electrical conductor is fixed with respect to the housing. Circuitry may be electrically connected to the flexible electrical conductor. The flexible conductor and circuitry may be provided by a flexible circuit board.

  • Patent number: 5525733
    Abstract: A process for preparing a compound of structure (I) or a hydrate or solvate thereof in which R.sup.1 is C.sub.1-6 alkyl, optionally substituted phenyl or optionally substituted phenylC.sub.1-6 alkyl, which comprises reacting an azide of the structure (II): M.sup..sym. N.sub.3.sup..crclbar. with a cyanoformate of the structure (III): NC.CO.sub.2 R.sup.1 in which M is an alkali metal atom, and R.sup.1 is as described for structure (I), to form an intermediate salt of structure (IV), in which R.sup.1 is as described for structure (I) and M is as described for structure (II) followed by conversion of the salt (IV) to the free tetrazole (I) or to a hydrate or solvate thereof.

  • Patent number: 5138057
    Abstract: A process for the preparation of a compound of formula (I) ##STR1## which process comprises reacting a compound of formula (II): ##STR2## wherein the amino group is optionally protected, with a side chain intermediate of formula (III): ##STR3## wherein Q is a leaving group, R.sub.x and R.sub.y are protected hydroxymethyl or acyloxymethyl, or group(s) convertible to hydroxymethyl or acyloxymethyl; and R.sub.z is hydrogen or a group convertible thereto; and thereafter converting the 6- and 8- chloro substituents to hydrogen by means of reduction; converting R.sub.x and R.sub.y when other than hydroxymethyl or acyloxymethyl, to hydroxymethyl or acyloxymethyl, optionally converting R.sub.x /R.sub.y hydroxymethyl to acyloxymethyl or vice versa, deprotecting the 2-amino group where necessary and converting R.sub.z, (when other than hydrogen) to hydrogen; and optionally forming a pharmaceutically acceptable salt thereof.
