Patent CA-2108442-C (CA)
Inventor: ROBERTS JEFFREY B
IPC: H02H3/34

Granted: 2000-04-25
Abstract: The angle between the negative sequence and zero sequence currents for a power signal on a transmission lute is measured and compared against a plurality of successive angle ranges from 0° to 360°.      If the angle is 0° ~ 30°, an AG fault is indicated and a first section output is produced blocking ground elements BG and CG and phase-to-phase elements AB and CA. Art angle of 120° ~ 30° indicates a BG fault, resulting in a second output blocking ground elements AG and CG and phase-to-phase elements AB and CG, while a phase angle of 240° ~ 30° indicates, a CG fault, resulting in a third output blocking ground elements AG and BG and phase-to-phase elements BC and CA. If the phase angle is not covered by the above three primary ranges, then a second stage of comparisons arc made, including determining the magnitudes of the phase-to-phase distance elements, and then comparing the phase-to-phase resistance of the lowest of those with the apparent resistance of the one ground element, i.e, AG, BG or CG, associated with the non-primary (secondary) range of angles which includes the measured phase angle.    If selected criteria are met, then an output is asserted to block the ground and phase-to-phase elements noted above associated with that ground element.

Abstract: A computer-based media data processor for controlling transmission of digiti zed media data in a packet switching network. When the processor receives a request from a network client node for presentation  of specified media data stream presentation  unit seque nces the processor in response retrieves media data from a corresponding media access  location, determines  the media data type of each prese ntation unit in the retrieved media data, and designates  each retrieved presentatio n unit to a specified media data presentation  unit sequ ence based on the media data type determination for that presentation unit. The processor then assembles a sequence of presentation descriptors fo r each of the specified presentation unit sequences, all presentation descriptors i n an assembled sequence being of a common media data typ e, and then assembles transmission unit packets each composed of at least a portion  of a presentation descriptor and its media data, all presentation descriptors and media data in an assembled  packet being of  a common media data type. The assembled packets are the n released for transmission via the network to the client processing node requ esting presentation of the specified presentation unit s equences.

Abstract: Self-heating characteristics of a spontaneously combustible catalyst are reduced by treating the catalyst with an oxygen-containing hydrocarbon having at least 12 carbon atoms. The treatment is particularly suitable for reducing the self-heating characteristics of sulfidable metal oxide(s)-containing catalysts, presulfurized catalysts, presulfided catalysts or induced catalysts. When applied to sulfur-containing catalysts, the treatment gives a catalyst that has suppressed self-heating properties without substantially compromising sulfur retention or activity. Further hydrocracking catalysts treated by the oxygen-containing hydrocarbons give improved product yield. Further, a method of safety unloading a catalyst from a reactor is provided where the catalyst in the reactor is treated with a liquid mixture containing the oxygen-containing hydrocarbon to wet the catalyst.

Granted: 2001-02-20
Abstract: A disposable absorbent product such as a sanitary napkin or an urinary pad including a liquid-permeable cover layer, and absorbent core and a liquid-impervious layer  for preventing body exudate  entrapped  in  the absorbent core from contacting the wearer's undergarment or skin. A secondary liquid containment structure for intercepting body exudate leaking past the side edges of the  absorbent  product  is  mounted  underneath  the liquid-impervious  layer.  The containment  structure includes a transversely extending strip of absorbent material such as non-woven fabric, having longitudinal end  portions  forming  liquid-acquisition  zones.  The central portion of the absorbent strip constitutes a reservoir  layer  for  collecting  the  body  exudate discharged  on  the  liquid-acquisition  zones.  In  a preferred embodiment, the longitudinal end portions of the strip are sufficiently long to form tabs capable of being folded about the edges of the undergarment for stabilizing the absorbent product against the perineal region of the wearer.  In a variant, the positioning tabs incorporate the secondary liquid-containment structure. Each positioning tab includes a layer of porous material enclosed on all  sides by a liquid-impermeable layer except at a side edge portion that is adjacent to the side edge of the disposable absorbent product. The side edge portion of the positioning tab constitutes a liquid-acquisition zone capable of intercepting body exudate leaking  past  the  edge  of  the  disposable  absorbent product.

Abstract: A reagent pack for keeping fluids with or without suspensions mixed or suspended upon rocking. The reagent pack has at least one chamber divided into separate sub-chambers with a throat region between them defined by baffles for agitation of suspended reagent during rocking of the reagent pack. A continuous lid sealable to the pack has membrane sealed apertures in the lid for allowing access to the underlying chambers and sub-chambers by withdrawal needles. A tray is configured to hold multiple side-by-side reagent packs on respective slides that slide in and out for insertion and withdrawal of the packs. During operation, the tray and associated packs are rocked such as by being periodically inclined with respect to horizontal, providing reagent agitation.      Optical annunciators proximate the tray indicate respective reagent pack activity under control of a computer which stores information on the contents of each pack at each tray location and correlates it to scheduled reagent use in a medical testing system. The tray is provided with a thermally conductive hinge. The tray with packs is located in an enclosure.
