Patent CA-2215519-C (CA)
Title: Anti-theft device for protecting electronic equipment
Inventor: WINGARD PETER F
IPC: G08B13/14
Filed: 1996-04-04
Granted: 2001-02-20
Abstract: Security (e.g., theft-disincentive) for portable electronic appliances is provided by integrating a decoder into the power supply of an electronic appliance which prevents the electronic applicance from being powered up in the absence of a unique code impressed by an emitter on the power lines feeding power to the electronic appliance, and permits the electronic appliance having a decoder to be powered up (i.e., power-uppable) only in the presence of the unique code. Electronic appliances having the detector incorporated (e.g., integrated) therein are termed "protected equipment". The emitter may be "fixed" by hard-wiring same to the power lines in a household (e.g., behind a switch or receptacle face plate), or may be "portable" so that the user can transport and use (e.g., power up) the protected equipment at an other location simply by plugging the emitter into a receptacle at the other location and located in a safe place. The detector is integrated into the protected equipment in such a manner that bypassing its function (or removing the decoder) will render the equipment inoperable (or, would be cost prohibitive).

Abstract: Phosphates are removed from a hydrocarbon stream by first contacting the hydrocarbon stream with a polar material, wherein the polar material chemically reacts with phosphates in the hydrocarbon stream and binds to the phosphates and then separating the hydrocarbon stream from the polar material. Contacting the hydrocarbon stream with the polar material preferably, particularly for large volume applications at a refinery, may comprise passing the hydrocarbon stream through a fixed filter bed composed of polar material that is insoluble in water or oil, wherein the hydrocarbon stream is separated from the polar material upon passage through the fixed filter bed. Contacting the hydrocarbon stream with the polar material may also comprises, particularly for use at a well site, mixing the hydrocarbon stream with an aqueous acid or base solution. Apparatus for carrying out the methods is also provided.

Abstract: Apparatus for driving fastening elements, such as nails, bolts, clips and the like, into a receiving material includes a magazine extending laterally outwardly from a guide.   The magazine holds a carrying strip for the fastening elements and a transport slide which, in cooperation with the magazine, can be shifted parallel to the driving direction of the apparatus.  The magazine has a housing and a guide channel opening into a transport channel in the guide.  The guide channel is formed by two laterally spaced guide rails each with a surface facing the other and profiled with tooth-shaped projections having tooth flanks of different lengths with the flanks facing the transport channel being shorter.  A first guide rail can be displaced away from a second guide rail parallel to the length of the guide channel by the transport slide.  The transport slide interacts with a control cam located on the first guide rail.  Both the first and second guide rails can be shifted laterally against the force of a spring.

Abstract: L'invention a trait à un procédé ainsi qu'à l'appareil correspondant permettant d'isoler plusieurs secteurs et ce, afin d'effectuer un traitement, une fracturation au sable notamment. Il est possible de pomper la barrière la plus basse dans une colonne d'exploitation (12) et de l'ancrer dans des trous tubés ou ouverts. Dans le mode de réalisation préféré, le bouchon pompé (20) comporte un élément visco-élastique (74) contenant un mélange d'agrégats particulaires (87), tel que décrit dans le Brevet (Etats-Unis d'Amérique) 5 417 285. Ce matériau visco-élastique est soumis à une force modifiant sa forme de telle sorte qu'il obstrue le forage. Cette modification de forme se solde également par une déshydratation du matériau à l'intérieur de l'enveloppe visco-élastique du fait d'un déplacement de fluide, occasionné par une diminution de volume, un bouchon consistant en matériau visco-élastique se constituant alors du fait d'un durcissement dudit matériau. Il est, par la suite, mis en place une garniture d'étanchéité (14) dans la colonne de tubage (12) de manière à isoler le secteur aux fins d'une fracturation au sable. Ce processus peut être répété sans exécution de manoeuvre de remontée au fur et à mesure que des bouchons auxiliaires sont pompés dans la colonne d'exploitation et que se réitère le processus. A la fin de la fracturation, il est facile de broyer ces divers bouchons, de facture simple et économique.

Title: Bluff body premixing fuel injector and method for premixing fuel and air
Inventor: MORFORD STEPHEN A
IPC: F23D14/82
Filed: 1998-12-14
Granted: 2007-04-10
Abstract: A tangential entry premixing fuel injector (10) for a gas turbine engine combustor includes a pair of offset scrolls (18) whose ends define a pair of entry slots (36) for admitting primary combustion air tangentially into a mixing chamber (28) bounded by the scrolls (18) and by longitudinally spaced endplates (14, 16). An array of fuel injection passages (42) extends along the length of the slots. The passage stray is configured to inject a primary fuel nonuniformly along the length of the air entry slots and to control the fuel penetration depth d in proportion to slot height H. The injector also includes a flame disgorging centerbody (48) having a bluff tip (54) longitudinally aligned with the injector's discharge plane (22) and a secondary fuel conduit (80) extending through .the centerbody for discharging a secondary combustible fluid, preferably gaseous fuel, through a series of fuel discharge openings (84) in the tip (54). The flame disgorging centerbody improves fuel injector durability by resisting ingestion of combustion flame into the mixing chamber (28) and reliably disgorging any flame that is ingested. The controlled fuel penetration depth reinforces the flame disgorging capability of the centerbody by preventing fuel from penetrating into the slowly moving boundary layer attached to the centerbody (48). The bluff character of the centerbody, in combination with its longitudinal alignment with the fuel injector discharge plane, makes the centerbody capable of anchoring the flame at the discharge plane so that combustion occurs aft of the discharge plane where the combustion flame is unlikely to damage the scrolls or centerbody. Introduction of fuel or fuel and air through the openings in the bluff tip encourage the flame to become anchored to the tip and therefore spatially stabilizes the flame, resulting in additional attenuation of acoustic oscillations and further improved combustor durability. The longitudinally nonuniform injection of primary fuel compensates for any mixing nonuniformities attributable to the flame disgorging centerbody and therefore augments flame stability. The injector and an associated method of premixing fuel and air prior to combustion suppress formation of nitrous oxides, and improve the durability of both the injector and the combustor.
