Patent CA-2027500-C (CA)
Inventor: LE BIHAN DENIS
IPC: H04L12/54
Filed: 1990-10-11
Granted: 2000-01-11
Abstract: The incoming cells of a input asynchronous time-division multiplex channel (mtr) are counted by a counter (FFB) assigned to each virtual circuit which is incremented on each incoming cell of the virtual circuit and decremented periodically. Clock signals define consecutively numbered cell times (ntc). Queue and chaining table (FAVE, FCVN) define a cell time queue (FAF, FAL, FAV) specific to each of the cell times, a virtual circuit being assignable to a cell time by writing its identifier into the corresponding cell time queue. A controller (MC) uses the content of the cell time queues (FAF, FAL, FAV) and, for each cell time, identifies a virtual circuit to be processed and decrements the counter (FFB) belonging to this virtual circuit. The controller further includes arrangements whereby any virtual circuit whose counter is not idle is assigned to one of the cell times to be decremented by virtue of the arrival of this cell time.

Title: Moisture resistant electrically conductive cements and methods for making and using same
Inventor: WEI TAI SHING
IPC: H05K3/32
Filed: 1990-11-14
Granted: 1998-01-06
Abstract: An electrically conductive cement which when used to bond electrically conductive mating surfaces provides substantially stable conductivity characteristics under high humidity conditions, comprised of a carrier that provides a volumetric shrinkage of more than about 6.8 % (vol.) and a conductive filler including agglomerates, particles, powders, flakes, coated nickel particles, and coated glass spheres, having size and surface characteristics that maintain stable electrical contact by forming a moisture resistant contact with an electrical component lead. The carrier having a volumetric shrinkage between the uncured and cured states of greater than about 6.8 % (vol.) appears to effect a compaction of the filler particles causing the particles to be forced into enhanced electrical contact with the surfaces to be connected and to provide a measure of compaction between the particles themselves to enhance particle-to-particle conduction. The shrinkage of the polymeric carrier during curing places the interior particles under compression with sufficient force to urge the particles into engagement with one another as well as to cause the particles to penetrate non-conductive oxides that may be present on a component lead.

Title: Method and apparatus for controlling the flow of fluids
Inventor: KAWABE RYU
IPC: F16K7/06
Filed: 1992-09-02
Granted: 2003-03-18
Abstract: A method and apparatus is provided for controlling the flow rate of a fluid that flows through a fluid path including a resiliently deformable portion.        A first roller has a cutout formed thereon on one side thereof, and a retainer is arranged in parallel with the first roller. The resiliently deformable portion of the fluid path is held between the first roller and the retainer. The first roller is rotatably supported by its rotary shaft. The first distance from the rotary shaft to the outer wall of the first roller on the side facing opposite the resiliently deformable portion may be varied in response to the variation in the angle that occurs when the first roller rotates about its rotary shaft. Thus, the second distance from the outer wall of the first roller on the side facing opposite the resiliently deformable portion to the retainer may be varied in response to the variation in the first distance, and the shape in cross section of the resiliently deformable portion may be varied according to the variation in the second distance. The flow rate of the fluid may be controlled by varying the shape in cross section of the resiliently deformable portion of the fluid path in this manner. The retainer may be replaced with the second roller having the configuration symmetrical with the first roller and being rotatably supported.

Title: Power amplifier saturation detection and correction method and apparatus
Inventor: BLACK GREGORY R
IPC: H03G3/20
Filed: 1992-05-08
Granted: 1997-07-01
Abstract: A power amplifier controller for detecting saturation of the power amplifier (203) and correcting the automatic output control voltage (231) to avoid any further saturation. The controller detects the power of the RF output signal (211). Generates a signal (229) correlated to the detected power. Compares changes in that signal (229) to changes in the voltage of the AOC signal (231) in a comparator (217). The comparator (217) generates a signal (233) correlated to saturation of the power amplifier (203) for a DSP (223). The DSP checks the status of this signal (233). Upon detecting saturation, a algorithm contained within the DSP methodically reduces the voltage of the AOC signal (231) until there is a change in the power of the RF output signal (211).

Title: Improved salt basket for crystallizer and method of use in zero liquid discharge industrial facilities
Inventor: SOLOMON ROBERT L
IPC: C02F1/00
Filed: 1993-04-21
Granted: 2001-08-14
Abstract: An improved salt basket for dewatering solids. The salt basket is ideally configured for use with a crystallizer or evaporator producing salts from industrial wastewaters. The salt basket system includes a pressurizable vessel having a screen floor situated above a bottom liquid collection head, an inlet for the brine/solids slurry from which solids are to be separated and dried, an inlet for air, an inlet for steam (the latter two inlets may be combined, where convenient), a feed brine inlet and a drain outlet (these two may by combined where convenient into a combination feed/drain connection), an automated system for introducing feed brine, and an automated system for removing the solids product, the latter system including an automated door with a fail safe clamp system design.      The vessel shape preferably includes sidewalls of substantially circular cross section with downwardly and outwardly sloping walls (either conical or flaring somewhat at the bottom) which are free from protuberances which would tend to prevent salt crystals from falling downwardly. A pivotally attached lower door has a hydraulic failsafe closure mechanism and looking safety latches to prevent the door from inadvertently opening. The process control design minimizes exposure of the salt basket interior to supersaturated solutions with precipitating solids therein, thus reducing coaling of the salt basket, by introducing feed brine rather than magma (crystal/concentrated liquor slurry) to the salt basket between crystal harvest cycles.
