IPC: G06Q20/00
Filed: 1999-07-01
Abstract: L'invention concerne un système permettant la conduite d'une transaction financière à distance entre un client et un commerçant. Pour chaque transaction le client reçoit un code de transaction délivré par une autorité (24) responsable de la transaction, ce code pouvant être utilisé à la place du numéro de compte du client sur lequel les fonds seront retirés par le commerçant à l'exécution de cette transaction. Un code d'adresse est extrait de moyens (27) de mémorisation, ce code représentant le lieu de livraison auquel les biens et/ou les services fournis par le commerçant doivent être envoyés à l'attention du client. Le client autorise la transaction lorsqu'il fournit le code de transaction au commerçant. Pour exiger de fonds de la part du client, le commerçant transmet un montant ainsi qu'un code de commerçant à l'autorité (24) de transaction. Lorsque la transaction est validée par l'autorité (24) de transaction, le code d'adresse et un code d'acceptation sont envoyés au commerçant et lui permettent de faire transférer les fonds sur son compte. Le commerçant peut effectuer une contre-vérification des moyens (27) de mémorisation en entrant le code d'adresse pour obtenir une adresse physique ou électronique correspondante à laquelle les biens doivent être délivrés.

Abstract: L'invention concerne un procédé de production d'acier, selon lequel une matière de charge comprenant du fer directement réduit et, éventuellement, de la ferraille d'acier est introduite en continu dans un four à arc électrique fixe. A l'intérieur du four sont maintenus un bain d'acier en fusion et une couche de laitier continue, le bain d'acier présentant un volume correspondant à approximativement 7 à 13 volumes de piquage. La chaleur servant à faire fondre le matériau de charge est de préférence fournie par des arcs ouverts entre les électrodes et le bain de métal, la couche de laitier étant de préférence surchauffée jusqu'à une température dépassant d'environ 40 à 150 °C la température du bain. Pour qu'une surchauffe excessive soit empêchée, le laitier présente un point de fusion qui est sensiblement égal ou supérieur à la température du bain, la température de fusion du laitier pouvant être réglée par variation de la quantité de MgO contenue dans le laitier. De préférence, le laitier présente une faible alcalinité pour que le taux d'érosion réfractaire soit réduit. Le procédé de production d'acier est de préférence mis en oeuvre dans une installation de production d'acier dans laquelle un four de réduction directe est couplé au four à arc électrique. De préférence, le four à réduction directe est monté au dessus du four à arc électrique, de sorte que le fer réduit directement peut entrer dans le four à arc électrique sous l'effet de la gravité, en passant par des conduits inclinés.

Patent CA-2002100-A1 (CA)
IPC: G01N33/536
Filed: 1989-11-02
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for conducting measurements of electrochemiluminescent (ECL) phenomena includes a cell unit having an electrode configuration for inducing the emission of ECL light by the application of a selected voltage waveform to a sample fluid including an ECL moiety.  The sample fluid is transported to and from the cell unit by a flow-through pump/tubing system.  A photomultiplier tube detects the intensity of light emitted by the sample fluid during the ECL measurement process.  A computer control unit both analyzes the detected data and provides digital control signals to the cell unit to generate effective voltage waveforms.  The digital control signals are supplied to a novel pulse width modulated digital to analog converter which outputs a ramp voltage waveform having the desired slope.

Patent CA-2013924-A1 (CA)
Inventor: BROWN THOMAS A
IPC: H04B7/24
Filed: 1990-04-05
Abstract: A digital voter system for a mulit-site public service trunking (PST) digitally trunked RF communications system operates on the principle that it is highly likely that messages received during a system redundancy removal period are redundant messages. For a given RF channel, digital receiver is associated with each of multiple sites and receives digital messages reported to it by its associated sites. The multiple digital receivers are connected to a digital selector via a service request line (FSL) and a serial data line (BSL). Digital receivers which have messages to transfer to to then digital selector attempt to seize the service request line and, if they successfully seize it, maintain the line in its seized state for the redundancy removal period. Digital receivers which have messages but discover the service request line is already seized simply discard their messages. Since it is likely that two digital receivers may successfully seize then service request line at or near the same time, a windowing technique is used to schedule the times different digital receivers may apply their messages to the serial data line. If a digital receiver sees signals on the serial data line before it is scheduled to begin transmitting, it discards its message and aborts its transmission attempt. The preferred embodiment voter thus handles messages very rapidly (to reduce system latency time) while effectively removing most redundant messages and reducing or eliminating data collision on the shared serial data bus.

Abstract: WATERCUT MEANS AND METHOD WITH DEBRIS REDUCING TEST CELL         (79,060 -F) ABSTRACT      A petroleum stream microwave watercut monitor of the present invention includes a test cell having a petroleum flowing through it. A source, connected to a first antenna located within the test cell, provides microwave energy to the first antenna so as to irradiate the petroleum stream in the  test  cell with microwave  energy.   A  second  antenna located in the test cell and connected to a detector outside of the test cell receives the microwave energy that has passed through the petroleum stream and provides it to the detector.   The  detector  provides  an  intensity  signal corresponding  to  the  received  microwave  energy.    An indicator provides  an indication of the watercut of the petroleum stream in accordance with the intensity and the phases difference between the microwave energy provided by the source and the received microwave energy.  The test cell means also includes means for reducing an amount of debris in a portion of the petroleum stream flowing between both antenna.

IPC: A61F13/49
Filed: 1990-08-22
Abstract: Disposable absorbent articles such as a diaper or a sanitary napkin having a fastening system comprising a pressure-sensitive adhesive fastener having a textured fastening surface. The pressure-sensitive adhesive fastener comprises a backing web having bulbous surface aberrations projecting from a surface of the web and a layer of pressure-sensitive adhesive coated over and bonded to at least a portion of the surface of the bulbous surface aberrations of the backing web. When the fastening system of the present invention is affixed to a diaper, the overlapping portions of the diaper are maintained in contact with each other while the fastening system prevents separation of the overlapping waist portions because it is able to resist the wearer-generated peel forces encountered during wear and the shear stress encountered when the diaper is worn. Further, the fastening system allows the user to easily refasten and check the diaper for soiling and removing the diaper without rendering the fastening system unrefastenable or the diaper unusable.
