Title: Flow pulsing method and apparatus for the increase of the rate of drilling
Inventor: WALTER BRUNO H
IPC: E21B21/10
Filed: 1996-04-29
Abstract: A simple and economical device is placed in a drill string to provide a pulsating flow of the presserized drilling fluid to the jets of the drill bit to enhance chip removal and provide a vibrating action in the drilling itself thereby to provide a more efficient and effective drilling operation. Operation of the device is such that a pronounced negative pulse precedes the positive pulse. Between pulses there is a short time delay and this feature will further enhance drilling rates. Device automatically bypasses all fluid if it is disabled.
Patent CA-2184317-A1 (CA)
Inventor: KUNDRAT DAVID M
IPC: C21C7/068
Filed: 1996-08-28
Abstract: A three-stage process for obtaining metallic Cr units insitu during the production of stainless steel. Raw chromite ore or a concentrate produced from chromite ore is mixed with a carbonaceous reductant and slagging agents are added to an iron bath (24) for smelting and refining in a refining reactor (10). During the first stage, partially metallized chromite is smelted by carbon in the reactor that is top-and bottom-blown with oxygen and oxygen-containing gases respectively to produce a chromium alloy bath having a carbon content well below saturation. In the second stage, the alloy bath is decarburized by being bottom stirred with the oxygen-containing gas to the final bath carbon specification. In the third stage, the alloy bath is reduced by a metalloid reductant such as silicon or aluminum and again bottom stirred but with a non-oxidizing gas to achieve a high chromium yield. The reactor includes a top lance (18) extending through a throat (14) with a lower portion (20) of the lance extending to a point just above the bath and means (22) such as a tuyere or porous plug mounted at or near a bottom (16) and extending through a refractory lining (12) for stirring the iron bath containing dissolved carbon. Lance (18) includes a central passage (34) for injecting a compact, focused jet oxygen gas (30) that can penetrate through a slag layer (26) for decarburization of the iron bath and an outer passage (32) for discharging an oxygen gas (28) above the bath for post-combustion of CO to CO2. Passage (32) includes a plurality of evenly spaced annular diverging nozzles (33). The lance also includes a pair of concentric conduits (36) and (38) for conducting a coolant.

Title: Active cooperative tuned identification friend or foe (actiff)
Inventor: DUBOIS JACQUES
IPC: G01S17/74
Filed: 1996-11-01
Abstract: An optical identification friend-or-foe (IFF) system for vehicles comprises an active cooperative identification friend-or-foe (ACTIFF) system wherein a responder optical head is located on each friendly vehicle. That responder optical head comprises a number of small panels arranged in an array with surfaces of adjacent panels being at an angle to each other, the outer surfaces of the panels being coated with laser paint designed to emit radiation at one or more selective wavelengths when subjected to a suitable interrogation pump beam. Those selective wavelengths form an identification code for a vehicle. In operation, an interrogating vehicle would transmit a narrow well-collimated infrared (IR) beam towards a target vehicle causing laser paint on the coated surfaces to emit the selective wavelengths when subjected to that IR beam.      These wavelengths can then be detected by the interrogating vehicle for identification purposes.

Abstract: Des systèmes et des procédés de traitement du sang créent des conditions d'écoulement à tourbillons dynamiques (130), à l'intérieur d'une chambre de traitement (40), en amenant le sang sur un parcours de séparation qui s'étend sur une circonférence autour de l'axe de rotation le long d'un parcours d'entrée qui est sensiblement parallèle à l'axe de rotation. Les conditions d'écoulement tourbillonnaire font passer le sang sur le parcours de séparation, en vue de la séparation en ses constituants.

Patent CA-2218621-A1 (CA)
Title: Prosthetic heart valve
Inventor: EMKEN MICHAEL R
IPC: A61F2/00
Filed: 1996-05-07
Abstract: A bileaflet heart valve incorporates a pivot arrangement that minimizes resistance to downstream blood flow in the open position yet has prompt response and minimal regurgitation upon flow reversal. A valve body, having an axially curved preferably toroidal entrance that smoothly joins a generally cylindrical body of extended axial length, provides excellent fluid flow when combined with leaflets that can assume orientations aligned with the dowstream flow of blood. A pyrocarbon valve body receives a suture ring that permits the tissue annulus to directly contact its exterior surface, e.g. in a concave toroidal surface region for an aortic valve. Identical flat leaflets can assume a parallel orientation in the fully open position or can assume other low energy positions. Flat ears extend laterally from the leaflets and interengage with cavities of unique design having upstream (57) and downstream (59) lobes separated by an intermediate throat (65) portion defined by inward and outward fulcrums. The downstream lobes locate leaflets in the parallel open orientation and can optionally cause prerotation. As soon as reverse flow begins, upstream displacement of the leaflets causes the ears to contact straight camming surfaces (67) located upstream of the outward fulcrums which, in combination with the fulcrums and a downwardly directed, concave surface at the upstream end of the upstream lobe, positively guide each leaflet through efficient closing which ends in sustantially rotational movement.

Abstract: In a telecommunications network of the kind comprising a transport network (not shown) and an intelligence platform (2) any creation of additional services packages by a service creation environment (not shown) results in an interchange of informtion between a distributed computing environment (222) and the service creation environment. The service control environment forwards data defining the resources required and the start and finish time to the (222). The resource function (41) within the distributed computing environment determines whether the resources are or will be available, or if not whether an altenative quality of service at a different period could be provided. This information enables the service creation environment to guarantee the quality of service to be provided on implementation of the additional service package.
