Patent CA-2231672-A1 (CA)
Inventor: SABATOWSKI JOHN A
IPC: B65H15/00
Filed: 1997-07-15
Abstract: A sheet inverter is used in a method of handling documents, preferably to invert the documents, change them from an in-line configuration to a shingled configuration, and then move them in a direction substantially transverse to the original direction of conveyance of the documents. An inverter shaft is rotatable about a generally horizontal axis and has a plurality of sheet supporting elements, such as rods or bars (such as in an exaggerated generally S-shaped configuration) axially spaced from each other along the shaft, with each sheet supporting element comprising first, second and third portions defining first, second and third closed sides for receipt of a document, and an open fourth side by which the document may enter the elements. A support structure connects each of the sheet supporting elements (either together or individually) to the shaft for rotation with the shaft about its axis. The sheet supporting elements receive one or more documents at a first vertical level, which documents are sensed by a sensor. The supporting elements are then rotated with the shaft to deposit the documents (in association with stops) on a lower conveyor. The sheet supporting elements pass through openings between elements of the bottom conveyor and move back to the original position, which is sensed by another sensor, to await the next set of documents.
Patent CA-2232792-A1 (CA)
Inventor: R S NEN JUHA
IPC: H04W28/22
Filed: 1996-09-25
Abstract: D'une manière générale, l'invention concerne des services de transmission de données dans les systèmes de communications mobiles. Il est fréquent qu'un abonné mobile puisse accéder à différents types de téléservices et de services supports. Actuellement, chaque débit de données d'utilisateur correspond à un service support indépendant. On a donc un grand nombre de services supports, ce qui occasione des difficultés aux opérateurs de réseau et aux abonnés mobiles. L'invention vise à réduire le nombre de services supports en élargissant la définition du service support à plusieurs débits de données et en négociant, au niveau de l'établissement des communications, le débit de données associé à la communication de données dans le service support entre la station mobile (MS) et le réseau de communications mobiles (MSC). La phase suivante consiste à négocier le débit de données entre le réseau de communications mobiles (MSC) et le réseau fixe, à savoir par exemple: RTPC ou RNIS. Ensuite, le cas échéant, on adapte le débit de données du réseau de communications mobiles et les resources de canaux radioélectriques au débit de donnée utilisé dans les transmissions vers le réseau fixe.

Title: Ultrasound rate of flow measurement method and appartus
Inventor: SMYCHLIAEV VLADIMIR
IPC: G01F1/66
Filed: 1998-04-29
Abstract: The invention relates to an ultrasound flow rate measurement method using a measuring tube and at least two ultrasound transducer pairs which are located on the measuring tube and each form a measuring path, whereby the radial components of at least two measuring paths differ from each other relative to the measuring axis and wherein the measured flow rate of a flowing medium is determined from the velocity of the medium along at least two measuring paths. Such a known ultrasound flow rate measurement method is further developed in accordance with the invention in that the turbulence intensity in the medium is determined from the velocity of the medium along the measuring paths, that at least an approximation of the ratio of the angular momentum to the axial momentum of the medium is taken into consideration for the determination of the turbulence intensity, and that the measured flow rate is corrected using the turbulence intensity value so achieved.
Patent CA-2233990-A1 (CA)
Inventor: LEINS EBERHARD
IPC: D04B15/48
Filed: 1996-09-17
Abstract: For supplying yarns, a yarn supply apparatus is contemplated that is designed particularly for knitting machines whose yarn demand fluctuates greatly over time. The yarn supply apparatus has a rotor-driven yarn wheel, which in the ideal case furnishes yarn directly to the knitting machine or its yarn guides without the interposition of yarn storage devices. The yarn tension is monitored by means of a yarn tension sensor, which provides measured value detection for a closed-loop controller that controls the supply by the yarn wheel. The controller is also embodied such that it can process signals that contain information about the future yarn demand. Thus in the event of imminent drastic changes in demand, of the kind that in flatbed knitting machines periodically occur at the edges of the knitted goods (turning points of the yarn guide), the controller can react by presupplying yarn or by ceasing to supply yarn. Yarn tension spikes and overly steep yarn tension drops can thus be compensated for. The controller may be designed such that it functions as a closed-loop status controller and intermittently as an open-loop controller. Other provisions, such as disturbance variable compensation, parameter adaptation, or the like, are possible.
