Abstract: La présente invention a pour objet un procédé et un dispositif destinés à former des fibres artificielles et une bande de non-tisséconstitué desdites fibres. Le dispositif comprend un générateur de courant fluidique pratiquement continu le long d'un axe principal, au moins une filière (59) située à proximité du courant fluidique continu, destinée à extruder une résine liquédifiée dans les fibres, un dispositif servant à entraîner les fibres dans le courant fluidique principal, et un perturbateur (86) servant à perturber sélectivement l'écoulement du fluide dans le courant fluidique en faisant varier la pression du fluide d'un côté ou de l'autre de l'axe principal afin de produire des fibres frisées qui formeront la bande de non-tissé. Le procédé de fabrication faisant l'objet de la présente invention permet de contrôler avec précision les caractéristiques de la bande de non-tissé, telles que la résistance à la traction, la porosité, les propriétés d'arrêt, le pouvoir absorbant et la douceur par variation de la fréquence et de l'amplitude des perturbations auxquelles le courant fluidique est soumis. Enfin, ledit procédé et le dispositif correspondant peuvent être utilisés en combinaison avec les techniques de fusion-soufflage, de fabrication de non-tissé "spunbonded" et de formage concomitant, en vue de la fabrication de bandes de non-tissé. L'invention porte également sur des non-tissés à pouvoir sorbant élevé et sur leur utilisation en tant qu'absorbants d'huile, ainsi que pour d'autres applications.

IPC: H04W88/02
Filed: 1997-12-17
Abstract: The power radiated from mobile communications handset antennas has tended to increase in order to increase the distances between the handsets and base stations or communications satellites. These handsets, in use, excite if currents in the body and the body actually forms part of the radiator for the handset. Public fears have arisen over the use of such handsets, and in particular, repeated prolonged use. The present invention addresses this problem and provides a mobile communications handset arrangement comprising a microphone, an ear-piece, a transceiver, and an antenna; wherein the antenna is detachable from the handset, whereby reduced radiation effects are experienced by users.

Title: A two-element energy meter having systems for automatic service type detection
Inventor: HEMMINGER RODNEY C
IPC: G01R21/133
Filed: 1998-03-24
Abstract: A 2-element, three voltage connection electronic energy meter is disclosed for measuring 3-phase electrical energy supplied by a 4-wire delta service without external potential transformers. The meter employs non-isolating voltagesensors for sensing the line voltages and includes and an automatic service type detector and isolation detector. The meter generates voltage and phase angle measurements for each of the two voltages sensed by the meter. The service type detector compares the phase angles to automatically determine the service type supplying the electrical energy to the meter. The isolation detector compares the two voltages to automatically determine whether or not the installation includes external potential transformers. If the service type is a 4-wire delta service and no external potential transformers are used at the installation for isolating the voltage signals, the meter doubles the voltage measured over the first of the two elements when generating power measurements.

Patent CA-2234776-A1 (CA)
Title: Combination main reservoir and air system
Inventor: CUNKELMAN BRIAN L
IPC: B01D53/26
Filed: 1998-04-15
Abstract: A combination gas drying and reservoir apparatus includes a reservoir, a membrane dryer disposed inside the reservoir and a control scheme that reduces the amount of gas lost as sweep gas from the dryer.  The reservoir has an inlet flange that receives moisture  laden gas  from a  compressor,  an outlet flange from which dried gas discharges to a pneumatic system and a purge flange.  The dryer includes a vessel encasing a membrane unit between its inlet and outlet ends.   A purge port of the vessel communicates with the purge flange to form a purge channel.  The inlet end of the vessel is connected to the inlet flange from which it receives the moisture laden gas.   The moisture laden gas then flows into the membrane unit.   Sweep gas that has permeated through membranes flows from  a  sweep  space  defined  between  the  vessel  and  the membrane unit to the purge channel.  Dried gas flows out of the membrane unit through the outlet end of the vessel into the reservoir.  The control scheme includes a purge valve and a mechanism for controlling the purge valve.   Connected to the purge flange,  the purge valve can be closed to prevent sweep  gas  from  exhausting via  the  purge  channel  to atmosphere.   When the compressor is unloaded,  the mechanism closes  the purge valve  thereby preventing  sweep  gas  from expelling to atmosphere.  When the compressor is loaded, the mechanism opens the purge valve thereby allowing sweep gas to exhaust to atmosphere via the purge channel of the apparatus.

The temporarily passivated precipitation agent can be a complexed multi-valent metal ion, which is displaced from the complex by the activator.  The temporarily passivated precipitation reagent can also be a compound with pH-dependent ion strength which is activated by a proton-delivering or proton-accepting compound.  The temporarily passivated precipitation reagent can also be a polyamine which is activated by protonizing or quaternizing.

A reduced search area whose center is defined by the scaled motion vectors is provided. The motion compensation scheme is suitable for use with scaled frame mode or field mode video.  Various processor configurations achieve particular scaleable coding results.  Applications of scaleable coding include stereoscopic video, picture-in-picture, preview access channels, and ATM communications.

Title: Image signal encoding system capable of correctly encoding an editing image signal before and after switching time points of selection of input dynamic image signals
Inventor: KOGA TOSHIO
IPC: H04N21/234
Filed: 1998-06-01
Abstract: In an image signal encoding system, a change point detecting device detects a change point of a switching request signal to produce a change point detecting signal as a B picture ban signal. An encoding mode determining device periodically produces I picture mode signals, P picture mode signals, and B picture mode signals when the encoding mode determining device is not supplied with the B picture ban signal. The encoding mode determining device produces an I picture signal in response to the B picture ban signal. The encoding mode determining device produces the I picture mode signal in an initial image plane frame of the editing image signal after a switching time point of selection of a first input dynamic image signal and a second input dynamic image signal in response to the B Picture ban signal. The encoding mode determining device produces the P picture mode signal in a final image plane frame before the switching time point of selection of the first input dynamic image signal and the second input dynamic image signal in response to the B picture ban signal. A register produces, by retiming the switching request signal in using the I picture signal which is produced in response to the B picture ban signal, a switching signal. A selector selects, as an editing image signal, one of the first input dynamic image signal and the second input dynamic image signal in response to the switching signal. An image encoding device encodes, in the I picture mode, the initial image plane frame of the editing image signal after the switching time point of selection. The image encoding device encodes, in the P picture mode, the final image plane frame before the switching time point of selection.
