Title: Procede permettant d'eliminer des substances toxiques de l'eau
Inventor: SANTINA PETER F
IPC: C02F1/62
Filed: 1996-08-14
Abstract: On élimine l'arsenic et le COT de l'eau potable ou des eaux usées en utilisant du fer métallique finement divisé en présence de soufre élémentaire en poudre ou d'autres composés soufrés tels que le sulfure de manganèse, et en procédant ensuite à une étape d'oxydation. On peut produire à cet effet un prémélange en ajoutant le fer, le soufre et l'agent oxydant à de l'eau dans une plage prédéterminée de pH. Le fer et le soufre sont mélangés pendant une durée qui est fonction de la température et du pH de l'eau, et de la présence dans l'eau de minéraux et d'acides organiques complexants ou séquestrants. On ajoute un agent oxydant au mélange et on agite de manière continue. Selon un mode de réalisation préféré, l'agent oxydant est du peroxyde d'hydrogène. Après un temps de réaction suffisant, on décante l'eau du mélange et l'on obtient un prémélange concentré. Ce prémélange peut être ajouté à l'eau destinée à la consommation ou aux eaux résiduaires industrielles contenant des matières toxiques.

Abstract: A door latch assembly has a housing (14) defining a mouth (48). A detent fork (44) is pivotally mounted within the housing to cooperate with the mouth to pivot between an open and closed condition for receiving, engaging and cinching a keeper of a striker.     The detent fork (44) is biased in the open condition. A pivotally mounted pawl (50, 54) is biased into engagement with the detent fork for retaining the detent fork in the closed condition. A pivotally mounted inside release arm (34) is movable between a stand-by position and a release position and biased to the stand-by position.     A pivotally mounted outside release arm (32) is movable between a stand-by position and a release position, and biased to the stand-by position. A pivotally mounted locking cam (58) operably engages the pawl (50, 54) for positioning the pawl to selectively engage the release arms (34, 32). The locking cam (58) is rotatable between an unlocked position for urging the pawl to engage at least one of the arms (34, 32), a single lock position for urging the pawl to engage at most one of the arms (34, 32), and a double lock position for urging the pawl (50, 54) to disengage both arms. A double lock lever (66) operably engages the rotatable locking cam (58) for rotating the locking cam between the unlocked position, the single lock position and the double lock position. A single lock sub-assembly comprises a handle lever (94) coupled to the rotatable locking cam (58) for rotation therewith between the unlocked position and the single lock position and uncoupled from the rotating locking cam when the rotatable locking cam is rotated between the single lock position, and the double lock position.

Patent CA-2267843-A1 (CA)
Inventor: DULTZ WOLFGANG
IPC: H04N5/238
Filed: 1999-04-01
Abstract: Described herein is a device for local attenuation of light intensity in the viewing area of a light-sensitive viewing and/or recording device (CCD), this being suitable, in particular, as an anti-glare device for video cameras used in video phones or suitably equipped PC's. The device comprises a first objective (L1) and a point-resolving ferro-electric liquid-crystal modulator (PC, LC) that is arranged between two polarizers (P1, P2), with a photo-conductive layer (PC) and a subsequent liquid-crystal film (LC) that is of helical, smectic liquid crystals that is in contact with this layer. The photo-conductive layer (PC) is located essentially in the image plane of the first objective (L1) that is mapped by a second objective (L2) onto the viewing and/or recording device, when bright light sources or backgrounds are suppressed without any dimming or blooming of the image. By eliminating the intermediate imaging, the viewing and/or recording device (CCD) can, as an alternative, be arranged in the image plane of the first objective (L1), in which case, the second objective (L2) is eliminated. The liquid-crystal modulator (PC, LC) is then arranged in close proximity to and in front of the viewing and/or recording device (CCD), so that bright sources of interfering light are not only made darker, but are also blurred.

Title: Integral spring consumables for plasma arc torch using contact starting system
Inventor: CURRIER BRIAN J
IPC: H05H1/34
Filed: 1997-09-17
Abstract: Disclosed is a novel method and structure for contact starting a plasma arc torch. A translatable, electrically conductive component such as a nozzle or swirl ring in biased into contact with an electrode by a compliant spring element.      A pilot arc is formed by first passing current through the electrode/component interface. Thereafter, the component is translated under the influence of gas pressure in a plasma chamber formed between the electrode and component, compressing the compliant element and initiating the pilot arc. The spring element may be maintained integrally with the nozzle, swirl ring, or a retaining cap, facilitating removal and replacement of the spring element with consumable components of the torch. Exemplary spring elements include wave spring washers, finger spring washers, curved spring washers, helical compression springs, flat wire compression springs, and slotted conical discs.

Patent CA-2276227-A1 (CA)
Inventor: LANGFORD NEWTON
IPC: F24H9/20
Filed: 1999-06-23
Abstract: A domestic water heater 10 includes a water meter 14 to count the units of water used each day and has a timer 17 to time the heating cycle each day. A programmable means 18 stores the water usage and heating data for a sixty day period and using statistical techniques determines the time period required for heating the water in the tank 10. The means 18 also stores power load curve data from the power generator and matches the required heating time to an appropriate portion of a low in the power load curve. The tanks may be placed in any one of 9 groups and a tank in each group will by virtue of the program in means 18 centre the mid point of the calculated heating period on the same time during the off peak period. Tanks fitted with such controllers can be allocated into one of two or more categories to enable a power utility to reallocate the water heater power load into low cost periods of the power load curve.

Filed: 1998-03-16
Abstract: L'invention concerne un procédé permettant de produire de l'énergie à partir de fuel-oil résiduel que l'on désalphate avec un flux de vapeur industrielle de façon à produire un courant d'huile désalphatée. Ce courant d'huile désalphatée est brûlé dans un gaz porteur d'oxygène pressurisé de façon à produire un courant de gaz chaud pressurisé. Ce courant de gaz chaud pressurisé se détend dans une turbine qui produit de l'énergie motrice et un courant de gaz détendu. Le courant de gaz détendu est refroidi en transférant la chaleur qu'il contient vers un flux d'eau d'alimentation, qui devient un courant. Une partie de ce courant s'intègre, au moins partiellement, au flux de vapeur industrielle utilisé pour désalphater le fuel-oil résiduel, ce qui fait que le désalphatage et la génération de vapeur se produisent dans le même temps.

Abstract: An authentication server is provided which stores authentication details of authorised users, and a list of currently-authenticated users. A number of application servers are connected to the authentication server, to allow the application servers to check the current authentication status of a user which requests service by the application servers. A session key is generated during the authentication procedure, for use during subsequent communications. One embodiment of application server which is adapted for use in combination with the authentication server is a file transfer server which allows authenticated users to upload files using a first session key generated during authentication of the sending user, and which allows a recipient to retrieve the file in encrypted form using a second session key which is generated during the authentication of the second user. The file transfer server also allows a file sender to specify a release date for data transmitted to the server. In one embodiment, the transmitted file is doubly encrypted using not only the session key of the recipient, but also an encryption key which is released to the recipient only after the specified date and time. In another embodiment, the file is stored on the server until such time as the specified date and time have passed, before being released to the recipient.
