Title: Collier de friction pour colonne
Inventor: GLAESENER PIERRE
IPC: B29C45/67
Filed: 2000-03-15
Abstract: L'invention concerne un mécanisme (10) permettant d'appliquer une force de serrage sur un élément (20) en forme de colonne tel qu'une colonne de presse. Ce mécanisme de serrage comprend un élément (22) compressible qui entoure la colonne (20) et vient saisir la colonne et transmettre une force de serrage à cette dernière. Cet élément compressible peut coulisser le long de la colonne. Ce mécanisme comprend en outre un piston (40) de serrage permettant d'appliquer une force de serrage. Ce piston (40) de serrage comprend un orifice (44) traversant qui comprend une surface (46) de contact destinée à recevoir l'élément (22) compressible de manière à produire un frottement entre ce dernier et la surface de contact. Ce frottement entre l'élément (22) compressible et la surface (46) de contact empêche le glissement relatif de l'élément compressible et du piston de serrage. Ce mécanisme comprend en outre un piston (50) coulissant permettant d'appliquer une force de serrage et entraînant le glissement de l'élément (22) compressible le long de la colonne entre une position initiale et une position de précharge dans laquelle la surface (46) de contact entre en contact avec l'élément (22) compressible et le comprime lorsque l'élément passe d'une position à l'autre. Lorsqu'une compression est exercée sur l'élément compressible, ce dernier vient saisir la colonne et applique une force de serrage initiale. On applique la force de serrage principale à l'élément compressible, et par conséquent à la colonne, en déplaçant le piston (40) de serrage de manière à le mettre en position de serrage. L'invention concerne également un procédé permettant d'appliquer une force de serrage sur un moule au moyen du mécanisme de serrage décrit.

Title: Modele de masque de phase et masque de phase pour l'ecriture de reseaux de bragg de fibres optiques
Inventor: SHENG YUNLONG
IPC: G02B6/02
Filed: 2003-01-22
Abstract: La présente invention concerne un système et un procédé permettant de concevoir des réseaux de Bragg fibrés (FBG) multi-canaux efficaces, au moyen d'un masque de phase précompensé permettant de diffracter la lumière pour l'écriture latérale du réseau sur un noyau de fibre optique. Une fonction de phase souhaitée des réseaux de Bragg fibrés (FBG) est engendrée, conçue notamment pour un espacement efficace entre le masque de phase et le noyau de fibre optique. A partir de la fonction de phase, un masque de phase est pré-compensée pour décaler des effets de diffraction associés avec chaque position longitudinale de la lumière de réception de réseaux de Bragg fibrés (FBG) à partir de deux positions longitudinales correspondantes du masque de phase espacées symétriquement et longitudinalement par rapport à chaque position longitudinale spécifique de réseaux de Bragg fibrés (FBG). Les deux positions longitudinales correspondantes du masque de phase sont espacées longitudinalement l'une de l'autre par un espacement déterminé par l'espacement efficace entre le masque de phase et le noyau de la fibre et par le premier angle d'ordre de diffraction de la lumière à travers le masque de phase. Ce modèle implique des étapes du processus d'optimisation et de la transformée de Fourier pour des réseaux de phase binaire.

Title: Film-enrobed, unitary-core medicament and the like
Inventor: SADEK HANI
IPC: A61J3/07
Filed: 1989-11-21
Abstract: A medicine tablet is described as a new article of manufacture. The tablet is enrobed in a gelatin coating formed by application of respective layers of elastic gelatin film to opposite sides of the tablet. The applied gelatin layers conform tightly to the tablet surface, bond securely to the tablet, and are sealed together in essentially edge-to-edge manner at a seal line which extends around the tablet at a desired place on the tablet. The gelatin layers can be colored differently from the tablet and differently from each other. A range of formulations are described for film which can be peelable from a tablet or other product core, and for films which bond to the core. A presently preferred formulation for producing tablets having a bonded tamper-evident coating comprises a water-based gelatin preparation having about 45% gelatin and about 9% plasticizer (glycerin and/or sorbitol) by weight. Method and apparatus for producing such new products are also described. Product cores can be dispensed on a self-timed basis into essentially simultaneous contact with two enrobing films which are supported on locally recessed coacting rotary dies. The cores contact the films adjacent a nip between the dies at places on the films which overlie die recesses which are oversize relative to the cores. The films deform around each core and are sealed by the dies to each other before the dies coact to cut the enrobed cores from the films. A core feeding mechanism can include an alignment device which causes the cores to have a desired orientation as they are handled by the dies.

Patent CA-2015494-A1 (CA)
IPC: H04M1/00
Filed: 1990-04-26
Abstract: On-board equipment for a mobile telephone system has a function of reporting the degree of busyness of message channels available in a service area.  While the equipment is in a stand-by condition with no communication being held thereon, the degree of busyness is determined on the basis of electric field levels of individual message channels or control information sent from a control station.  When the electric field levels are used to determine the degree of busyness, the electric fields of a plurality of message channels assigned to the service area are detected.  If any of the msssage channels has an electric field level higher than a predetermined level, that message channel is determined to be busy.  The rate of use of the message channels is calculated by using the number of assigned message channels and the number of occupied message channels.  The calculated rate of use is displayed as information which is indicative of the busyness of the message channels.  When the busyness is determined on the basis of control information, a lockout signal sent from the control station and indicative of the fact that no idle message channels are available is detected.  The number of lockout signals having appeared within a predetermined period of time is determined and displayed as busyness information.
