Inventor: TURNER STUART HAROLD
IPC: F16B13/12
Filed: 2000-01-20
Abstract: A wall plug (1) comprises a body portion (2:30:30a:40) and a rotatable portion (3:31:31a:41) received therein, the rotatable portion having a passageway (13:32:32a:42) therethrough which is offset both from the axis of rotation of the rotatable portion and also from the axis of the passageway in the body portion in which the rotatable portion is received. The rotatable portion can thus be angularly adjusted to a selected position of offset between its passageway axis and the axis of the passageway in the body portion to compensate for a hole drilled to receive the wall plug being out of position.  The offset lead-in offered by the passageway in the rotatable position makes screw engagement easier than with a wholly misaligned wall plug. Means (16,17) are provided for retaining the rotatable portion in its selected adjusted position.

Abstract: An oxygen depletion sensor relies on the shift of a pilot flame away from a nozzle as the oxygen content of the combustion air decreases. A thermocouple is positioned so as to be in the flame during combustion at acceptable oxygen levels and in the unburned zone when the oxygen content is below an acceptable level. The large voltage difference between conditions of high and low oxygen content provide for a more reliable sensor.

Title: Commutateur intelligent pour fibre optique
Inventor: LIU JIAN-YU
IPC: H04Q11/00
Filed: 2000-06-02
Abstract: Selon cette invention, un commutateur optique à insertion-extraction commande la commutation et les niveaux de puissance de sortie par la manipulation des signaux destinés aux modulateurs de polarisation. A chaque port d'entrée, le faisceau est séparé en des composants de l'onde lumineuse dirigés horizontalement et verticalement. Un faisceau est décalé et les faisceaux similaires polarisés passent à travers un modulateur de polarisation qui fait pivoter la polarisation de manière contrôlable à un angle déterminé pour déterminer si c'est la polarisation horizontale ou celle verticale va prédominer. En cas de polarisation horizontale, les faisceaux passent à travers un séparateur de faisceaux de polarisation sans déflexion. En cas de polarisation verticale, les faisceaux sont réfléchis. On fait passer les faisceaux à travers un contrôleur de polarisation supplémentaire pour déterminer s'ils doivent être dirigés vers l'un des ports de sortie ou dissipés. Si l'option sortie est sélectionnée, on procède à la collimation des faisceaux avant de les émettre. Un filtre d'interférences sélectif en longueur d'ondes permet d'utiliser l'objet de l'invention comme un multiplexeur à n canaux à insertion-extraction entièrement configurable.

Title: Method of amplifying optical signals using erbium-doped materials with extremely broad bandwidths
Inventor: DIGONNET MICHEL J F
IPC: H04B10/2557
Filed: 2000-07-28
Abstract: In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide (810) made from a rare-earth-doped amorphous yttrium aluminum oxide material (e.g., erbium-doped yttrium aluminum oxide material). The optical input signals include optical signals having wavelengths shorter than 1,520 nanometers and optical signals having wavelengths longer than 1,610 nanometers. Pump light is applied to the optical waveguide (810) to cause the waveguide to provide optical gain to the optical input signals. The optical gain causes the optical signals to be amplified within the waveguide to provide amplified optical signals over the extended range from approximately 1,480 nanometers to approximately 1,650 nanometers, including, in particular, optical signals having wavelengths shorter than 1,520 nanometers and optical signals having wavelengths longer than 1,610 nanometers.
