Patent CA-2220603-A1 (CA)
Inventor: PENNINCKX DENIS
IPC: H04B10/43
Filed: 1997-11-27
Abstract: Afin d'augmenter la longueur de transmission de données binaires par fibre optique, le dispositif compense la dispersion chromatique engendrée par la fibre en effectuant une modulation à la fois de puissance et de phase de l'onde optique émise (S), de façon à créer un décalage de phase voisin de 180 degrés à l'intérieur de chaque cellule binaire dans laquelle la puissance optique est basse mais non nulle. Le dispositif comprend un interféromètre de type "Mach-Zehnder" (1) réalisé sur un substrat d'éléments III-V et conçu pour qu'en l'absence de tensions électriques (Va, Vb) appliquées sur ses électrodes (Ka, Kb) il crée des interférences destructives. Un circuit de commande (2) applique sur les électrodes (Ka, Kb) des tensions de commande (Va, Vb) ayant des composantes continues sensiblement égales, l'une au moins des tensions de commande (Va) résultant de la superposition d'une tension de polarisation (Vpa) et d'un signal filtré (ea) obtenu par filtrage passe-bas d'un signal électrique d'entrée (E). Application aux transmissions optiques à longue distance par fibres standard.

Inventor: EDWARDS CRAIG
IPC: A47G9/02
Filed: 1997-11-27
Abstract: A mattress cover includes a top panel, a skirt portion depending from the periphery of the top panel, and an elastic strip connected to the free edge of the skirt portion. The elastic strip has a width of between about 0.75" and about 3.0" so as to produce a strong elastic force holding the mattress cover in close conforming relationship on mattresses within a wide range of thicknesses. The elastic strip is sufficiently wide that ornamentation, including trademarks, logos and other symbols applied thereto, would be readily discernible when the mattress cover is not in use, but would not be plainly visible when the mattress cover is in use and therefore would not interfere with the aesthetic appearance of the bed.

Title: Apparatus and method for locking blades into a rotor
Inventor: PEPPERMAN BARTON MICHAEL
IPC: F01D5/30
Filed: 1997-12-30
Abstract: A blade is locked into groove in the periphery of a turbo-machine rotor by forming mating notches in opposing faces of the blade root and groove so as to form a blind hole. At assembly, a slotted radial pin is installed into the blind hole so as to prevent axial motion of the blade root. The pin is rotated so as to align its slot with a slot formed along the length of the rotor groove. A retaining strip is slid into the rotor groove slot so that it extends through the slot in the radial pin, with a pre--bent end of the strip resting against one face of the rotor. A tab formed on the other end of the strip is bent against another face of the rotor so as to lock the retaining strip in place. At dis-assembly, one of the retaining strip tabs is unbent and the retaining strip slid out. The pin is then extracted, thereby allowing the blade to be removed.

Title: In-band signaling for an hand-over operation in a mobile telecommunication system
Inventor: DE VRIENDT JOHAN ANDRE
IPC: H04L12/56
Filed: 1998-02-16
Abstract: A mobile telecommunication system with Base Transceiver Stations (BTS1-3) coupled to a mobile terminal (MT) via a radio link and exchanging mobile information (AAL-SDU: MUD, MSI) with a telecommunication controller (TC: BSC1-2; MSC). The mobile information contains a telecommunication signaling, such as an hand-over command (HOCOM), e.g. to be transported to the telecommunication controller. According to the ITU recommendation for the ATM Adaptation Layer AAL of the type 2 or 5, the AAL-PDU packets, which may for instance be transported by ATM cells, and wherein the mobile information is mapped, include a User-to-User indication field CPS-UUI or CPCS-UU, respectively, that transparently transports user data. This field is used to transport the telecommunication signaling in the up-link connection to a Base Station Controller (BSC1-2) or to a Mobile Services switching center (MSC), or, in the down-link connection, to base transceiver station (BTS1-3). The circuit (SARS1-2) which extracts this telecommunication signaling is relatively simple since the location of this signaling in the packet is well known because it corresponds tothe location of the user-to-user indication field. There is thus no need, for the circuit (SARS1-2) receiving a packet, to search for the telecommunication signaling in the whole packet received.

Abstract: L'invention concerne un système de freinage pour des patins à roulettes. Le système de freinage est monté à l'arrière du patin et il est actionné par le mouvement d'une pièce couvrant la cheville. Contrairement aux systèmes antérieurs, dans lesquels une plaquette de freinage s'engageant avec le sol est montée en pivotement sur le corps du patin, la plaquette de freinage de l'invention est conçue pour effectuer un mouvement coulissant dans l'extension à l'arrière de ce corps. Quand la pièce du patin couvrant la cheville effectue une rotation vers l'arrière, la plaquette de freinage effectue un mouvement de translation dans l'extension du corps pour entrer en contact avec la surface du sol. L'invention concerne également une plaquette de freinage améliorée destinée à un patin à roulettes.

Abstract: A secured receptacle holder (9) having two securing posts (10a and 11a) each with a clamping member (20a and 20b) and rib configuration (22a and 22b). The posts (10a and 10b) are connected by a clamping screw (19) that rotates clockwise to attach and counter clockwise to detach by a compression knob (12). Continued rotation clockwise causes the lower post (11a) to telescope into the main post (10a) while driving the clamping members (20a and 20b) toward one another. On other types of surfaces support is achieved by a pedestal base (31). The main post top (10c) has a smaller diameter with a securing cap (16) inserted into its top which keeps the support rotator (14) in place. The support rotator (14) has a thread stabilizer housing (15) containing a thread insert stabilizer (23).
