Title: Method and arrangement for effective radio transmission of data
Inventor: SCHLIWA PETER
IPC: H04J13/00
Filed: 1997-08-14
Granted: 2004-02-03
Abstract: Method and arrangement for effective radio transmission of data According to the invention, a method and an arrangement are provided for digital radio transmission of data between a fixed station (1) and at least one mobile station (2, 3) at one of a plurality of carrier frequencies (F1, F2 ...), the data being transmitted in a plurality of time slots (Z1, Z2 ...) using a time-division multiplex method. The change from one carrier frequency to another carrier frequency requires a prede-termined time period when so-called slow hopping RF modules are used. The data are transmitted in active time slots, which are each followed by an inactive time slot in which no data are transmitted and which is sufficient for the RF modules to programme the frequency for the next active time slot. According to the invention, the time duration of the inactive time slot is shorter than that of an active time slot.

Title: Symmetrical ultrasonic gas flow meter housing and related multi-configuration gas flow meter assembly
Inventor: MONTAG DENNIS R
IPC: G01F15/18
Filed: 2000-01-20
Granted: 2004-11-09
Abstract: An ultrasonic gas meter housing member is configured to provide an associated multi-configuration ultrasonic gas meter assembly. The housing member is installable in an ultrasonic gas flow meter which includes an internal flow measurement tube along which gas travels for flow measurement, the tube having an inlet end and an outlet end.  The ultrasonic gas meter housing member includes a closed back portion and a front portion spaced from the back portion to define a space for receiving the internal flow measurement tube such that the tube extends across the internal space of the housing member. At least one wall portion extends between the back portion and the front portion, the wall portion having a first opening and a second opening therethrough for connection of the housing member to a gas inlet pipe and a gas outlet pipe. The gas meter housing member is symmetrical about a plane which divides the housing member into a first portion and a second portion. The symmetrical configuration enables the housing member to receive the flow measurement tube in both a first orientation in which the first and second opening face in a first direction and the inlet end of the flow measurement tube is positioned in the first portion of the housing member and the outlet end is positioned in the second portion, and a second orientation in which the first and second opening face in a second direction substantially perpendicular to the first direction and the inlet end of the flow measurement tube is positioned in the second portion of the gas meter housing member and the outlet end is positioned in the first portion. The first and second orientations are particularly useful in enabling the housing member to be used both in gas meter installation sites where the gas pipes extend downward and in gas meter installation sites where the gas pipes extend upward.

Title: Pressure testing apparatus and testing method for propane tank systems
Inventor: SHAW JIMMIE BRYANT
IPC: B65D90/50
Filed: 2000-02-23
Granted: 2010-10-05
Abstract: A method and assembly (kit) are provided for use by propane tank service personnel to detect escaping gas in propane tank systems. The standard connection between the regulator and tank service valve is replaced with a permanent valve assembly including a main connection between the regulator and valve and a valve unit disposed in a branch connection of the valve assembly. A separate pressure gauge is individually assigned to tank service personnel and adapted to be carried by such personnel in testing the pressure in the propane tank. The pressure gauge is affixed, e.g., through a hose, to a valve unit connector including an actuator, i.e., a valve stem operator, for actuating the valve unit. When the pressure gauge is connected to the valve unit, the latter is actuated to provide an immediate reading of the tank pressure. A determination is made from this reading whether the tank is out of gas, and if the tank is out of gas, the service valve is turned on, gas introduced, the service valve turned off and a further pressure check made to determine whether gas is leaking. In one embodiment, the valve unit comprises a saddle valve directly connected to the main connection over a drilled hole in the latter. In another embodiment, a manifold block, which includes a through bore and an orthogonal, communicating bore, mounts the valve unit.

Title: Implant intervertebrale ajustable
Inventor: BENOIT ALFRED
IPC: A61F2/44
Filed: 1997-08-06
Granted: 2003-12-23
Abstract: L'invention concerne un implant intervertébral se présentant sous la forme d'un corps d'appui (1) qui comprend une traverse centrale (2) et deux parties latérales (3, 4) solidaires de cette traverse centrale (2) et ne formant qu'une seule pièce avec celle-ci. Les parties latérales (3, 4) sont disposées dans deux plans (5, 6) s'étendant sensiblement parallèlement l'un par rapport à l'autre et séparés par la traverse (2), lesquels peuvent être appliqués, en tant que surface d'appui, sur des corps vertébraux adjacents. La traverse (2) comporte un cylindre de guidage (7) creux qui s'étend sensiblement parallèlement aux parties latérales (3, 4) et entre celles-ci, et comporte au moins un filetage (8; 28). Un dispositif d'écartement peut être introduit entre les parties latérales. L'implant intervertébral selon l'invention offre les avantages suivant: le rayon de lordose naturelle de la colonne vertébrale peut être rétabli de façon spécifique chez un patient, et cet angle peut être déterminé avant l'opération; l'on obtient ainsi, pour l'implant, des conditions de départ optimales de croissance interne; on fait appel à une technique d'insertion atraumatique, étant donné que l'implant peut être vissé avec délicatesse et de manière maîtrisée, au lieu d'être chassé; et l'on peut mettre en oeuvre une technique d'opération en trois étapes simplifiée (également avec effraction minimale) grâce à l'utilisation d'une tige de guidage.

Abstract: L'invention concerne l'utilisation de plusieurs techniques de traitement de signaux audio dans différentes combinaisons pour améliorer la qualité audio représentée par un flux de données formé par montage par collure de deux ou plusieurs autres flux de données. Ces techniques s'utilisent notamment dans des applications mettant en paquet des données audio avec des données vidéo. Dans une technique selon l'invention, on utilise des mots de commande de gain transportés avec le flux de données audio pour interpoler des niveaux sonores de reproduction à travers une collure. Dans une autre technique, on utilise des bancs de filtres spéciaux ou des formes de transformées TDCA pour supprimer des artefacts de repliement du spectre de part et d'autre de la collure. Dans une autre technique encore, on utilise des bancs de filtres spéciaux ou des fonctions de fenêtres de fondu enchaîné pour optimiser l'atténuation d'un dépassement de canal spectral créé au niveau d'une collure. Dans une autre technique, on convertit des fréquences audio échantillons en fonction de longueurs et de fréquences de trames pour permettre de mettre en paquet des données audio avec, par exemple, des données vidéo. Dans une autre technique enfin, on aligne de manière dynamique des blocs audio afin de pouvoir maintenir une synchronisation appropriée à travers une collure. On prend comme exemple une audio de 48kHz avec une vidéo NTSC.

Granted: 2004-11-30
Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) included in the switch (400) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals received from the deflector (172) and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs of deflectors (172) coupling a beam of light (108) between optical fibers (106).
