Title: Synchronous digital communications system, control installation, network element and central clock generator
Inventor: WOLF MICHAEL
IPC: H04J3/06
Filed: 1997-12-19
Abstract: The network elements NE1, ..., NE6 of a synchronous digital communications system must be synchronized with each other without the possibility of clock loops occurring. A network node NODE contains network elements NE1, ..., NE6 and a central clock generator SASE.  The network elements transmit clock signals 2M to the clock generator, which contain a clock of a message signal STM-N and a quality indicator (SSM) contained in the message signal which reflects the accuracy of the clock. The clock generator selects one of the clock signals 2M as the reference clock REF and informs the control installation STE which of the clock signals it has selected and the degree of accuracy of this clock signal. On the basis of this message STAT the control installation gives instructions ANW to the network elements with respect to the quality indicator which the network elements are to transmit to their outputs.

Abstract: Un procédé et un appareil permettent d'utiliser efficacement à la fois la puissance et la largeur de bande d'un système (102) de communications cellulaires dans lequel une unité mobile entre préférablement en mode veille lorsqu'aucune communication ne se produit entre cette unité et la station de base pendant une période prédéterminée mesurée par un temporisateur (601) d'inactivité. Lors de la cessation de validité du temporisateur (601) de veille, l'unité mobile sort du mode veille (603) pour déterminer si un message est en instance (606). De la même manière, la station de base transmet un message de notification TEI (identification temporaire du matériel) à toutes les unités mobiles afin d'informer chacune d'entre elles qu'un message est en instance. En sortant du mode veille pour recevoir les messages, l'unité mobile détermine la qualité de la transmission (608). Si celle-ci est suffisante (610) et que le message de notification TEI n'indique pas de données en instance, l'unité mobile retourne en mode veille (601), même si elle se situe dans une cellule autre que celle associée à la station de base actuellement assignée à cette unité mobile.

Title: Edge rolling device for dough pieces
Inventor: SIROIS GABY
IPC: A21C11/00
Filed: 1999-02-26
Abstract: The device is used for rolling an edge of a dough piece. It comprises a first mechanism for making a friction engagement with the edge of the dough piece and a second mechanism for moving the first mechanism inwards relative to the edge of the dough piece so that the edge is forced to roll on itself. For instance, this can be realised by a first plate having a plurality of elongated guiding slots. A plurality of followers are slidably mounted in corresponding slots of the first plate. A dough-engaging finger is connected to each follower. The fingers are located under the first plate and moved relative to the dough piece. The device mechanically rolls the edge or edges of a dough piece to form an elevated peripheral portion that prevents the toppings from falling or flowing out of the dough piece during the preparation or when cooked and served by the customers. It also gives a better appearance to the final products. The device may be used in an industrial food preparation process and replaces the manual forming of the elevated peripheral portion that required a large number of persons. It resolves the problem of having large quality variations from one dough piece to another, since the final result of the manual rolling operation depended in most part on the skills and concentration of each individual.
