Abstract: Procédé de production d'un élément destiné à une cellule de production d'aluminium et constitué d'une matière composite à base de carbone renfermant un borure, carbure, oxyde ou nitrure métallique réfractaire, ou des combinaisons ou mélanges de celui-ci et d'aluminium, de titane, de silicium et de zirconium, ainsi que leurs alliages et précurseurs. Le procédé consiste, dans un premier temps, à former un mélange réactionnel d'aluminium, de titane, de silicium ou de zirconium et de précurseurs aptes à réagir de manière à former le composé métallique réfractaire, et éventuellement de matières de charge et d'additifs. On mélange le mélange réactionnel avec 1 à 20 parties en poids de carbone particulaire pour 1 partie en poids du mélange réactionnel; ainsi qu'avec un liant colloïdal renfermant au moins une substance choisie parmi la silice, l'alumine, l'yttria, l'oxyde cérique, la thorine, la zircone, la magnésie et l'oxyde de lithium colloïdaux, en une quantité suffisante pour mouiller la totalité des particules de carbone. On soumet le mélange ainsi obtenu au compactage et au séchage puis on le chauffe afin de déclencher une réaction micropyrétique auto-propagée du mélange réactionnel.

Title: Alkali metal diffusion barrier layer
Inventor: FINLEY JAMES J
IPC: C03C17/34
Filed: 1995-09-11
Granted: 2000-01-11
Abstract: The present invention provides thin metal oxide barrier layers which prevent migration of alkali metal ions from glass substrates which comprise alkali metal into coatings on the glass surface, the properties of which coatings are susceptible to deterioration by the presence of alkali metal such as sodium.  The barrier layers of the present invention are effective at unexpectedly thin thicknesses, and have an optimal thickness range which is unexpected, in view of the expectation that a barrier layer will be increasingly effective with increasing thickness.

Title: Optical switching apparatus and method for use in the construction mode testing of a modular fiber administration system
Inventor: REAGAN RANDY ALAN
IPC: G02B6/44
Filed: 1997-07-31
Granted: 2000-03-07
Abstract: A device and method for connecting an optical switch to the optical fibers that terminate on a fiber distribution shelf within a fiber administration system. The optical switch device contains a support plate that is shaped essentially the same as the protective cover of fiber distribution shelf. As such, the support plate of the optical switch device can be joined to a specific fiber distribution shelf by substituting the support plate for the protective cover. An optical switch is affixed to the support plate, wherein the optical switch is sized not to extend beyond the peripheral boundaries of the support plate. As a result, when the support plate is placed over a fiber distribution shelf, the optical switch joined to the support plate does not obscure any other fiber distribution shelf in the fiber administration system.

Granted: 2008-07-08
Abstract: The invention relates to indicator ink compositions that contain a water-based dispersion of a phenol-formaldehyde resin, at least one colorant and an amine- terminated catalyst. These indicator ink compositions are fixed to a surface, such as by drying, and respond to specific conditions of time, temperature, humidity, pressure and the presence or absence of certain chemicals by changing color. Compositions provide a means for detecting exposure to a predetermined condition and can be fixed or otherwise attached tonearly any article or designed into patterns on materials. Exposure of the indicator ink to the specific condition, the indicator ink provides a permanent detectable record of the event. Further, by varying the amount of amine-terminated catalyst in the formulation, the specific conditions at which the indicator composition will change color can be altered. Such compositions are specifically useful for determining the effectiveness of a sterilization process.
