Title: Commercial kitchen exhaust system
Inventor: BUSSY ERIC P
IPC: F24F11/76
Filed: 2000-02-01
Abstract: An air control system (33) for an exhaust system (32) of a commercial or institutional kitchen (12) of a facility (10) in which the volume rate of air exhausted may be increased to improve the comfort, health, and safety conditions in the kitchen (12) and the rest of the facility (10). Comfort, health or safety may be determined by sensing a parameter in the ambient air environment (28), such as temperature and/or gas level. With the exhaust system (32) operating at a first volume rate to handle the activity of the cooking units 18, the air control system (33) causes exhaust system (32) to increase the volume rate toward a second, higher volume rate to exhaust more air from the ambient air environment (28) thereby reducing the temperature or gas level in the facility (10) to improve comfort and reduce load on a HVAC system (30) or to improve air quality which has health and safety benefits as well. Advantageously, the air control system (33) monitors exhaust temperature for an exceedance of a heat threshold, in which case fire control measures are taken.

Patent CA-2298266-A1 (CA)
Inventor: EDWARDS THOMAS J
IPC: H04M3/523
Filed: 2000-02-08
Abstract: A facility far adjusting a number of servers assigned to server pools for performing certain work types on the basis of unmet service needs in a work processing facility. Servers may include service agents, both human and robotic. A server assignor and a corresponding server assignment method may each be employed in a work distributor or an automatic call distributor ("ACD") to conditionally adjust sever availability in server pools.      The server assignor compares a composite preference value for a work type against each server's thershold value for the work type. When the server assignor determines that the composite preference value is greater than or equal to a server's threshold value, then the server assignor indicates that the server may be included in the server pool for that work type. Each server has preference values and threshold values for different kinds of work. The magnitude of a preference value represents an affinity for the work type. The server's threshold value represents a reluctance to perform work having that work type. The server does not normally receive work for which the preference value is less than the threshold value, unless the server assignor determines that the composite preference value exceeds the server's threshold value for that work type. The server assignor and corresponding server assignment method may compute the composite preference value from a number of user-selectable inputs and utilize a number of user-selectable functions.

Patent CA-2306897-A1 (CA)
Inventor: FUJIMORI YASUHIRO
IPC: H04N19/895
Filed: 1998-10-22
Abstract: La présente invention concerne un procédé permettant de coder un signal à la source. En particulier, l'invention permet de traiter un signal comprenant plusieurs éléments de signal, chaque élément de signal étant codé pour former un train binaire (130). Les bits d'un train binaire donné sont distribués entre différents trains binaires (140). De cette manière, les paramètres décrivant les composants des éléments de segment sont distribués entre différents trains binaires. Ces opérations de groupement et de distribution permettent de distribuer les erreurs entre plusieurs niveaux de reconstruction d'image. L'invention concerne également un autre procédé qui permet de mêler plusieurs niveaux et qui consiste à définir un signal en plusieurs niveaux, chaque niveau comprenant une trame, plusieurs pixels et plusieurs bits. Dans un mode de réalisation, le mélange s'effectue sur chaque niveau et entre les niveaux. Ce mélange entre plusieurs niveaux permet de distribuer la perte due aux erreurs groupées entre plusieurs niveaux et, de ce fait, de faciliter la reconstruction d'image des zones de l'image affectées par la perte.

Title: Electrical resistance heater insulator
Inventor: AUDET SERGE
IPC: D06F58/26
Filed: 2000-05-18
Abstract: There is disclosed an electrically resistance insulator for use in supporting a helical heater coil at seven locations on the coil. The insulator is supported from a support structure and has a pair of arms that extend from the base for supporting the heater coil. The arms have an intermediate slot and two inwardly extending notches at the bottom of the arms. The notches and the intermediate slot support three consecutive convolutions of the coil relative to the insulator at one axial side of the coil. The arms of the insulator further have shoulders which provide a widened slot area and defined lug portions at the upper parts of the arms.      The width of the lug portions taper outwardly to permit for two adjacent convolutions of the heater coil to be supported on opposing sides of each of the lug portions. Since two lug portions are provided, one for each arm, the heater coil is supported at four locations consecutive coil convolutions by the lug portions of the insulator. The lug portions extend beyond the shoulder to support the four coil convolutions at convolutions diametrically opposed and interleaved with the three consecutive coil convolutions of the one axial side of the coil. The heater coil is held in place reducing bowing of the heater coil above the insulator.

Title: Method of controlling special playback mode of video signal reproducing apparatus
Inventor: HAN YEON-TAEK
IPC: H04N5/92
Filed: 2000-05-30
Abstract: A method of controlling a run mode of a video signal recording/reproducing apparatus is provided. More particularly, a method of controlling a special playback mode of a video signal reproducing apparatus, by rejecting a special playback key input during comparison of program classes in an initial playback mode, and restricting run of a special playback mode while a video signal loaded with program class data is being reproduced, is provided. The special playback key command, which is input while the video signal with program class data is being reproduced, is refused, thereby preventing pictures from being output regardless of program class, because the program class cannot be exactly detected in a special playback mode.

Title: Introduction of air into injection water
Inventor: SUNDE EGIL
IPC: E21B43/16
Filed: 1999-01-07
Abstract: Air is introduced into the injection water for microbial enhanced oil recovery. The injection water is passed through an ejector where it is entrained and the oxygen subsequently dissolves in the water. In operation, the pump operates at a constant speed, pumping water to the wellhead, via the ejector. Air is drawn into the water stream at the ejector and dissolves in the water, by virtue of the high water pressure, between the ejector and the wellhead. The amount of air supplied is adjusted using the control valve and this is controlled in dependence upon the pressure in the air line measured by the pressure gauge and the pressure drop across the ejector measured by the pressure gauges. The amount of air drawn into the water is also affected by the proportion of water which passes via the bypass line, thus avoiding the ejector.
