Patent WO-03093848-A1 (WO)
Title: Procede et dispositif a utiliser dans des essais parametriques cc
Inventor: ROBERTS GORDON W
IPC: G01R31/30
Filed: 2003-04-29
Abstract: L'invention concerne un système et un dispositif pouvant servir pour réaliser un essai paramétrique CC sur une charge externe. Le dispositif peut être conçu pour appliquer une tension ou un courant voulu à ladite charge externe. Le dispositif de circuit reçoit un signal de paramètre de contrainte à une entrée (202) et libère à une sortie un signal à proximité du signal de paramètre de contrainte pour la charge externe. Le dispositif de circuit comporte un premier segment de circuit entre l'entrée et la sortie ayant une unité de recherche (199), un point de tension intermédiaire (214) et une charge interne (216) entre le point de tension intermédiaire et la sortie. Un second segment de circuit, relié en un système de rétroaction au premier segment de circuit, fournit à l'unité de recherche la tension à la sortie. L'unité de recherche est conçue pour produire un second signal de tension sur la base du signal de paramètre de contrainte et le premier signal de tension reçu et pour appliquer ledit second signal de tension au point de tension intermédiaire. L'application du second signal de tension au point de tension intermédiaire provoque une modification soit dans le signal de tension, soit dans le signal de courant à la sortie, ce qui provoque à la sortie un signal à proximité du signal de paramètre de contrainte. L'invention concerne en outre un circuit de mesure de courant conçu pour produire une mesure du courant à la charge externe pouvant être utilisé avec un dispositif de circuit produisant une tension.

IPC: H04L12/911
Filed: 1990-08-06
Abstract: Abstract of the Disclosure Disclosed is a call control method for use with an ATM switch for integrating and switching various types of information which differ in traffic characteristics, such as voice, data and motion images, using an asynchronous transmission mode (ATM).          When a call is made to the ATM switch, it is accepted only when it is possible to set a path that can guarantee the service requested by the call.  When a call is made to the ATM switch, a load representing how much of the capacity of input links and output links of a self-routing module (SRM) constituting the ATM switch is obtained from the average value and peak value of the bit rate of the call.  The load is added to each of current loads of the input and output links and buffers of the self-routing module which form a path in the ATM switch.  A determination is made as to whether or not the result of the addition exceeds the maximum load of each of the input and output links and buffers.  On determination that the maximum value is not exceeded, the call is accepted.
Patent CA-2024076-A1 (CA)
Inventor: DROUET MICHEL G
IPC: C22B4/08
Filed: 1990-08-27
Abstract: Disclosed is a plasma reactor for use to treat ores or other material at a very high temperature in order to physically or chemically transform the same. The reactor comprises a vertical, electrically insulated sleeve disposed at the upper end with a hollow torch of a conventional structure, for use to generate a plasma column. A gas is tangentially injected into the torch to create a vortex inside the same. The material to be treated is dropped, in powder form, vertically downward inside the sleeve from the upper end thereof, beside the hollow torch, so as to form a substantially uniform cylindrical curtain of particles falling down into the sleeve. The particles that are centrifugally projected against the internal wall of the sleeve by the vortex escaping from the hollow torch, entirely cover the internal wall of the sleeve and shield, while simultaneously being treated by heat generated by the plasma arc column. The reactor further comprises a crucible positioned under the sleeve to collect the treated particles in molten form, which drip down from the sleeve at the lower end thereof. The plasma column may be generated by the hollow torch exclusively, when the reactor is intended to be used in a non-transferred arc mode. The reactor may also be used in a transferred arc mode. In such a case, the arc is transferred to a melt contained in the crucible. Another electrode is provided for this purpose at the bottom of this crucible, and is electrically connected to the power supply.

Patent CA-2025385-A1 (CA)
IPC: E02D31/00
Filed: 1990-09-14
Abstract: In the system for removing volatile impurities from ground water by the generation of under-pressure within a well shaft that is driven into the area of ground water that is contaminated, a vertical flow of the ground water within the shaft itself and in the surrounding ground is enhanced by means of a suction pump within the shaft.  The output of this pump is controllable.  In addition, purification gas is introduced through a feed channel below the ground water plane.  After rising through the ground water, the gases are drawn off above the ground water plane and passed to a multi-stage filter system that incorporates connections to the feed pipe for the gases into the shaft.  By this means, controlled by means of an air choke, at least some of the purification gas can be returned to the well shaft.            ***

Title: Roll coater with perforated deckles
IPC: D21H23/60
Filed: 1990-09-19
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for maintaining a relatively placid pool of liquid coating material in the trough between two nipped rolls comprises a pair of deckles, one disposed near either end of the nipped rolls, each of the deckles having an edge generally conforming to a segment of the adjacent roll to effectively form an end of the trough formed by the rolls.      At least one of the deckles has one or more openings which permit the liquid coating material to flow laterally out of the trough and through the deckle at a rate proportional to the depth of the coating material in the trough.  Controlling the lateral outward flow of material from the trough stabilizes both the turbulence of the liquid coating material in the trough and the surface condition of the coating material.
