Title: Coated electrosurgical electrode and method of manufacture
Inventor: ARTS GENE H
IPC: A61B18/12
Filed: 1996-06-28
Granted: 2001-03-27
Abstract: A design and method of manufacture are disclosed for an electrosurgical electrode (10) with a silicone coating. The coating resists the build-up of eschar. The silicone material is thick enough in the flat area of the blade to withstand the electrosurgical voltage without breakdown. The electrosurgical current path is primarily through the blade edges (15) and tip. The flat of the blade remains insulated under most conditions. The relatively thick coating also provides high tear strength and added durability. The composition of the electrode (10) coatings may include silicone elastomers (11) in the form of adhesives, dispersions, or liquid rubbers. The coating composition may also contain adhesion promoters, heat stabilizers, plasticizers, release enhancers, cross-linking agents, and colorants. Several methods of manufacture are illustrated by way of examples.

Inventor: WIEDEMANN JIM LEE
IPC: E21B36/00
Filed: 1998-01-20
Granted: 2002-03-26
Abstract: Wellhead equipment includes a body having a drilling conduit passage, whereby drilling conduit is passed through the body. Polymer sealing elements are disposed within the body and disposed in relation to the passage to seal off well pressure. A circulation passage extends through the body in the vicinity of the polymer sealing elements. The circulation passage has an inlet and an outlet whereby warm fluid is circulated through the circulation passage from the inlet to the outlet thereby raising the temperature of the polymer sealing elements to improve their cold weather performance.

Abstract: L'invention porte sur un procédé destiné à réduire, en partie au moins, des oxydes de fer, consistant à mettre en place un lit de réactifs sur la sole d'un four à sole tournante, ces réactifs étant constitués a) d'un mélange fait de fines de minerai de fer et de matériau particulaire carboné et/ou, b) de micro-agglomérats de fines de minerai de fer et de matériau particulaire carboné. On chauffe le mélange et/ou les micro-agglomérats sur la sole du four à sole tournante afin de réduire, au moins partiellement, les oxydes de fer. Le diamètre de ces "micro-agglomérats" est inférieur à 1400 microns (et, de préférence, supérieur à 500 microns). On emploie ce produit, au moins partiellement réduit, à la production de fer métallique. Il est également revendiqué, au titre de cette invention, un appareil servant à réduire, au moins partiellement, des oxydes de fer. Le procédé selon l'invention permet à un four à sole tournante de fonctionner sans qu'il ne soit nécessaire de recourir à la pelletisation des fines de minerai de fer ni à celle du charbon.
Patent CA-2233880-C (CA)
Inventor: MACDOUGALL TREVOR W
IPC: G01R19/00
Filed: 1996-07-22
Granted: 2005-04-12
Abstract: A fiber optic, Faraday-effect current sensor (optical current transducer) which has improved temperature sensitivity due to compensation for temperature-induced variations of the Verdet constant. Fiber optic sensing coils can exhibit shifts in their bias angle due to a number of reasons, including physical rotation of the fibers, an apparent circular birefringence attributable to the sensing coil shape (Berry's phase), circular birefringence in the sensing fiber, or a DC magnetic field or current. The present invention takes advantage of the change in bias angle by identifying a preferred channel from the two sensing axes of the output fiber, based on the manner in which these axes respond to the change in bias angle. One of the axes will exhibit a change in sensitivity that exacerbates the change in sensitivity due to the Verdet constant, while the other channel will exhibit a change that complements, or compensates for, the change in sensitivity due to the Verdet constant. Once the preferred channel is identified, a polarizing fiber is attached to the output of the sensing coil, aligned to transmit the preferred channel to the optical detector.

Title: Method and arrangement for removing deposits in and on feed nozzles or feed pipes of firing installations
Inventor: SPICHAL PETER
IPC: F23L9/02
Filed: 1998-04-14
Granted: 2004-06-08
Abstract: In order to remove deposits in feed nozzles (20), which serve to recycle exhaust gas into the furnace of a firing installation, a lance (27) can be inserted into the feed nozzles (20) and is held in such a way as to be displaceable in its longitudinal direction. The lance (27) has a nozzle head (28) at its front end for the spraying of water and is connected at its rear end to a valve device (29), which can be adjusted via a control device (32) with regard to the water quantity, the water pressure and the opening and closing times. By means of the lance (27), water is sprayed in a finely distributed manner onto deposits (34) in the interior of the feed nozzle (20), as a result of which the water penetrates into these deposits and causes these deposits to be blasted off due to the development of vapour.

Le composant de complément peut être un composant hydrophobe ou un composant présentant une affinité élevée pour l'eau, et destiné à prolonger la durée de libération. On mélange la matière de la matière plastifiable, de l'amidon par exemple, avec au moins un plastifiant, de l'eau par exemple, et au moins un composant régulant le rythme de libération sous des conditions de mélange à faible cisaillement permettant de rendre plastique la matière plastifiable sans la détruire sensiblement et permettant d'obtenir une masse devenue plastique qui soit sensiblement homogène. Avant d'incorporer la masse plastifiée dans l'agent d'encapsulation, on réduit sensiblement la teneur en plastifiant et la température de la masse plastifiée de façon à éviter toute destruction sensible de l'agent d'encapsulation et de façon à obtenir un mélange formable et extrudable. L'extrusion du mélange par une filière se fait sensiblement ou pratiquement sans reprise de volume, le découpage donnant des particules discrètes relativement denses. Il est également possible de contrôler les propriétés de libération en préenrobant l'agent d'encapsulation et/ou en enrobant d'un composant filmogène les particules extrudées.

Abstract: An interface between a parallel backplane bus of a physical layer of a communication device and a higher layer of the device is provided in a manner compatible with a serial bus architecture such as IEEE 1394. The interface includes a parallel backplane physical layer controller having multiple receive data lines for receiving data from the backplane bus, and multiple transmit data lines for transmitting data to the backplane bus. A link layer controller is coupled to the parallel backplane physical layer controller, and communicates with the parallel backplane physical layer controller over a data bus. The parallel backplane physical layer controller can provide an effective data bandwidth which is greater than its operating clock rate. The parallel backplane physical layer controller may also be operative to support communications with the backplane bus using a plurality of different backplane bus widths, such as a single data bit bus width, a two data bit bus width, a four data bit bus width and an eight data bit bus width. The throughput data bandwidth of the interface can therefore be scaled by selecting one of the data bus widths supported by the parallel backplane physical layer controller.
