Patent CA-2325756-C (CA)
Title: Multi-step gas saver
Inventor: MCGUIRE DANIEL J
IPC: F17D3/01
Filed: 2000-12-13
Granted: 2001-10-23
Abstract: Natural gas and other industrial gases presently vented to the atmosphere can contribute to global warming or have other harmful effects. In this invention a multi-step process has been devised to save high-pressure gas contained within equipment that is being temporarily de-pressurized, gas which would otherwise be vented to atmosphere or burned, and return a portion of this saved gas directly to the equipment, when this equipment is to be returned to high pressure service. Depending on equipment size, saver vessel size, gas pressures, and the requirements of the user, gas venting could be reduced by amounts of from 70% to 99%. This invention is applicable to natural gas compressor stations and other facilities where natural gas is vented during operation or maintenance, or for use in other industries where toxic or harmful gases might otherwise be vented to atmosphere
Patent CA-2327687-C (CA)
Title: Adjustable retainer for electrical cords
Inventor: HOWARD CAROL A
IPC: H02G15/00
Filed: 2000-12-06
Granted: 2011-11-22
Abstract: A housing for an electrical wiring device includes an adjustable clamping mechanism for retaining electrical conduits therein. The clamping mechanism has a pair of opposing strain relief members on opposite sides of a conduit passageway, set to accept a predetermined conduit width. Each strain relief member has a frangible portion which can be removed by a user. In this manner, if a user desires to retain, by means of an interference fit, a conduit having a diameter larger than the predetermined spacing of the intact strain relief members will allow, one or both frangible portions can be removed to accommodate a larger sized conduit.  Alternatively, more than one pair of strain relief members having frangible portions can be alternately arranged to clamp a conduit in an S-shaped configuration, capable of accepting multiple conduit sizes by removing some or all of the frangible portions. Preferably, the strain relief members are integrally formed with the housing, and each frangible portion is integrally formed with the remainder of the strain relief member and the housing.

Granted: 2006-12-05
Abstract: Cette invention se rapporte à un nouvel ensemble plénum et dispositif d'étanchéité, particulièrement conçu pour former un plénum à l'intérieur d'un alignement circonférentiel d'aubes de stator dans un moteur de turbine à gaz. Le moteur de turbine à gaz comprend un compresseur d'air, une chambre de combustion et une trajectoire annulaire pour les gaz chauds, conduisant axialement les gaz chauds jusqu'à l'alignement d'aubes de stator circonférentiellement espacées, en amont du rotor de turbine. Chaque aube du stator possède un passage interne servant à conduire l'air de refroidissement entre une gaine radialement externe et un plénum TOBI (injection tangentielle de bord) qui accumule l'air de refroidissement pour l'expulser par des buses TOBI. Le plénum TOBI est défini: par une plaque avant; une plaque arrière; et une gaine interne disposée entre les plaques avant et arrière. L'amélioration proposée par cette invention concerne un nouveau dispositif d'étanchéité permettant la construction d'une gaine interne comprenant un ensemble circonférentiel de segments de gaine interne avec des joints s'étendant radialement entre les segments adjacents de la gaine interne. La gaine externe est constituée par un cerceau monobloc faisant partie intégrante des aubes du stator et de la gaine interne segmentée. Afin de permettre l'assemblage de la gaine interne pour qu'elle contienne l'air comprimé dans le plénum TOBI, on prévoit que l'enceinte du plénum contienne des éléments de boulonnerie allongés libérables, venant en prise avec les plaques avant et arrière et serrant les segments de la gaine interne entre ces plaques. Chaque élément de boulonnerie est disposé axialement à l'intérieur d'un joint associé entre des segments adjacents de la gaine interne, et chaque élément de boulonnerie comporte une chemise d'étanchéité disposée autour de l'élément de boulonnerie pour sceller le joint associé.

Title: Self-generation of certificates using a secure microprocessor in a device for transferring digital information
Inventor: MEDVINSKY ALEXANDER
IPC: H04L29/06
Filed: 2000-01-28
Granted: 2009-12-15
Abstract: The present invention allows consumer communications device in the figure such as an IP telephony adapter (110) to self-generate public key pairs (224) and certificates (214). This eliminates the need for such keys and certificates to be sent to the devices from an outside source so a single-trust ap-proach can be maintained. A manufacturer's certificate is installed into a device at the time of manufacture. The device only issues itself certificates based on a signed request from an external outside server. The device's self-issued certifi-cates incorporate information obtained from the server in a profile.  This allows control by the server over a device's self-issued certificates. In order to prevent tampering, and breaking, of the self-issued certificates, the certificate issuing process occurs within a secure microprocessor.
