Abstract: On décrit un dispositif destiné à enregistrer le fonctionnement d'une vanne (10) du type possédant un axe (16) que l'on peut tourner à l'aide d'une clé (20), afin d'ouvrir et de fermer la vanne, ce dispositif comprenant des moyens opérations (36) qui, lors de son utilisation, sont portés par la clé (20) et peuvent fonctionner indépendamment de tout autre dispositif ou appareil électronique, afin de détecter le mouvement rotatif de la clé, lors du fonctionnement de la vanne. De préférence, ces moyens opérants comprennent des capteurs (40, 42) sensibles au champ magnétique de la terre, et ils ont pour fonction de déterminer la rotation de la clé, par analyse des signaux produits par les capteurs. Grâce à cette détection des mouvements de la vanne à l'aide de moyens opérants placés sur une clé, on évite la dépense d'un dispositif de détection pour chaque vanne (le nombre total de clés étant bien inférieur au nombre total de vannes), de même que l'installation d'un matériel potentiellement fragile dans le milieu hostile dans lequel ces vannes foncionnent.

Patent CA-2205169-A1 (CA)
Inventor: KO WEN H
IPC: G01L9/12
Filed: 1995-11-09
Abstract: A capacitive absolute pressure sensor (10) includes a substrate (14) having an electrode (24) deposited thereon and a diaphragm assembly (12) disposed on the substrate (14). As pressure increases, the diaphragm (16) deflects, touches the electrode (24) (in the touch mode), and changes the capacitance of the sensor (10). The changed capacitance is sensed to thus sense pressure changes.  A burried feedthrough is used to sense the change in a capacitance in a chamber (34) under the diaphragm (16) and thus determine the pressure sensed.  A vacuum in the chamber (34) is maintained by proper selection of a thickness of a sensing electrode and an insulating layer (32), exposition thereof to a thermal cycle, and the hermetic bonding of the diaphragm assembly (12) to the substrate (14).

Patent CA-2212321-A1 (CA)
Title: A three-position solenoid valve
Inventor: AKAMATSU OSAMU
IPC: B60T15/18
Filed: 1997-08-01
Abstract: A three-position solenoid valve that can be used as a normally open type that can prevent reduction of responsivity due to the working pressure acting on a guide cylinder.  When the solenoid is demagnetized, it is made to adopt a connecting position and since the working pressure does not act on the guide cylinder that guides the sliding of the moving iron core of the solenoid in this connecting position, it is possible to prevent deformation of the guide cylinder by the working pressure, which would reduce the responsivity of the solenoid valve and reduce the longevity of the solenoid by having the working pressure acting on it for long periods.  Thus, it is possible to provide a valve that is suitable for use as a normally open three-position solenoid valve.

Abstract: Two half-logs (10 and 12), two lumber planks (10 and 12), or a combination of both half-logs and lumber planks are superposed on each other and adhesively joined, using adhesive (22), to form an intermediate assembly (24). Intermediate assembly (24) is then divided by one or more beam-long cuts made perpendicularly to the flat surfaces (14, 16, 18 and 20) of the two elongated half-logs, two lumber planks, or combination of both half-logs and lumber planks. Resulting sections (28 and 30) are substantially mirror-images of each other and are reoriented so that their outer edges, when part of intermediate assembly (24), now face each other. Also, resulting sections (28 and 30) are reoriented in such a way that space (32) remains between them. Various spacing elements or bracing elements are selectively chosen to connect resulting sections (28 and 30) to form a laminated, space-containing, wood-beam structure on which surface covering sheathing (50) or coatings may be applied.

Title: Methods for identifying service processing of telephone calls
Inventor: VISSER ELDRED JAMES
IPC: H04Q3/66
Filed: 1998-02-05
Abstract: The present invention comprises methods for efficiently identifying international outbound calls, in the telecommunications network (TN) of the outgoing country, which should be screened as possibly requiring processing according to a Global Virtual Network Service (GVNS), as opposed to conventionalinternational long distance (ILD) call processing. In particular, the present invention is directed to outbound international GVNS calls, known as "on-net," which are from one GVNS location to another GVNS location of the same customer. International calls that are not Outbound International GVNS On-net calls, referred to as Other ILD calls, include at least three types: standard ILD, non-GVNS data and international GVNS off--net calls. Standard ILD, non-GVNS datacalls and international GVNS off--net calls all have a routing number which comprises a country code (CC) followed by a national number (NN). In the presentinvention, all Outbound International GVNS On-net calls have a routing number which begins with a CC followed by a country code suffix (CC-suffix). Therefore,the presence of a CC-suffix after the CC in a call routing number indicates that the call should be screened as being, possibly, an Outbound International GVNS On-net call.

Title: Automatic gain control for free-space optical telecommunications links
Inventor: JAVITT JOEL I
IPC: H04B10/118
Filed: 1998-02-12
Abstract: Free-space optical transmission of analog information is facilitated by transmitting constant-amplitude pilot information with the other information. The amount of attenuation of the pilot information at the receiver is detected and used to control the amount by which received information is amplified. In this way the deleterious effects of free-space optical attenuation are substantially eliminated. The pilot information may be transmitted either via its own separate light frequency or wavelength, or as a distinguishable part of a larger quantity of information that is used to modulate one light frequency or wavelength.
