Title: Procede et dispositif de combustion d'un combustible
Inventor: SCHOLZ KARL-HEINZ
IPC: F23D14/22
Filed: 1998-01-24
Abstract: Selon l'invention, le combustible est introduit de manière centrale dans un tube de flammes (3) où il est mélangé avec de l'air de combustion dans la zone de combustion. L'air sort de premières et de secondes tubulures d'air (4 et 5) disposées en deux rangées (6, 7) directement adjacentes et inclinées à contre-courant à un angle de 60· par rapport à l'axe du tube de flammes. La distance (x) entre les gicleurs (9) et les embouchures des premières tubulures d'air (4) correspond à 0,70 fois le diamètre du tube à flammes. En outre les secondes tubulures d'air (5) font saillie à l'intérieur du tube à flammes d'une section (y) qui correspond à 0,17 fois le diamètre du tube à flammes. La section transversale globale des secondes tubulures d'air (5) correspond à 0,6 fois la section transversale globale des premières tubulures d'air (4). Il se forme un tourbillon toroïdal extrêmement turbulent dans le tube à flammes (3), qui produit un mélange très homogène au-dessus de la section transversale du tube à flammes (3). Il en résulte des valeurs très basses de NO¿x? et une répartition homogène de la température dès l'intérieur du tube à flammes.

Filed: 1998-05-29
Abstract: The present invention relates to the use of P-selectin as a targeting agent in radiotherapies for vascular related disease. P-selectin is translocated to the lume of vascular endothelia as a result of radiation. Thus, P-selecting provides a target for receptor-mediated delivery of drugs, including anticancer drugs and drugs for the treatment of vascular disease. However, Pselectin also plays a role in the activation of certain inflammatory cells and, as such, plays a role in radiation-induced inflammation. By interfering with P-selectin induction of inflammation, it is possible to modulate inflammatory responses to radiation therapy.

Abstract: A method and system for processing an enterprise's incoming customer communications on the basis of the enterprise's business objectives.  An enterprise service balancer distributes work based upon enterprise resources and immediate resource availability. The enterprise service balancer provides an instantaneous best possible service for a customer communication (e.g., a call) by matching the customer communication with the most appropriate available resource in the enterprise, as a whole, in accordance with the enterprise's definition of best service. The enterprise service balancer may refrain from moving media for a customer communication to an identified resource until after determining that the identified resource accepts the customer communication for further processing.  The enterprise service balancer looks for an enterprise resource having a specific skills set when the enterprise receives a customer communication requiring the specific skills set. The enterprise service balancer operates in conjunction with enterprise resources as diverse as call center agents, back office agents, and robotic call processing applications. The back office agents, such as technical star members, represent persons who do not typically handle customer communications. The robotic call processing system may operate in conjunction with an interactive voice response ("IVR") system or other such robotic system appropriate for the communications media. The enterprise service balancer may process customer communications arriving via media such as telephony, e-mail, video kiosk, and an Internet.

Title: Method and apparatus for transmitting control information over an audio data stream
Inventor: SLOAN DAVID G
IPC: H04J3/12
Filed: 2000-03-20
Abstract: The invention relates to a method and apparatus for transmitting control information over an audio data stream, such as PCM coded speech information. The device comprises a control unit having two inputs receiving the PCM speech samples and control information signal. Each PCM sample is made up of a plurality of bits arranged according to different significance positions, such as position 0, 1, 2, 3, ...N, where N+1 is the number of bits in the sample. The control unit receives a selected sample and shifts a bit at a selected significance position to a lower significance position. The empty slot at the predetermined significance position is used to receive a bit from the control information signal. The compound signal thus obtained is then released over a transport path, such as a T1 link, for transmission to a remote location. At the receiver, the control information bit is extracted from the selected sample at the predetermined significance position, and the PCM speech sample is recovered by shifting upwardly at least one bit at a significance position lower than the selected significance position.

Patent CA-2314153-A1 (CA)
Title: Corneal implant methods and pliable implant therefore
Inventor: SILVESTRINI THOMAS A
IPC: A61F9/007
Filed: 1998-12-18
Abstract: This invention involves an improved surgical method and associated apparatus for correcting refractive defects of the vision, using an intracorneal implant. A small radial incision is made in the periphery of the cornea, near the limbus and a blunt spatula is used to separate the lamellae of the corneal stroma. A circular interlamellar pathway through the stroma is formed using either a single 360 degree blunt, arc-shaped dissector tool or a pair of clockwise and counterclockwise 180-200 degree dissector tools. The circular pathway created defines the margin or outer boundary of an intracorneal channel that will be formed. The intracorneal channel is then expanded radially inward in a controlled stepwise fashion to widen the channel or to create an intracorneal pocket. This is done by introducing a dissector tool with a side leg into the incision and moving the dissector tool in an arcshaped path to widen the intracorneal channel. A single 360 degree dissector tool or a pair of clockwise and counterclockwise 180-200 degree dissector tools can be used. Dissector tools with progressively longer side legs are used to expand the channel until the desired width is achieved or until a complete intracorneal pocket is created. An intracorneal implant, which may be a split ring, segmented ring or continuous ring intracorneal implant or an intracorneal lens implant, is inserted into the channel or pocket and the incision is closed. The intracorneal implant is positioned remotely from the incision so that less stress is exerted on the incision during healing. The surgical apparatus, including the blunt, arc-shaped dissector tools and the side-leg dissector tools can be designed to be operated manually or with a vacuum centering guide which allows careful and precise control over the intracorneal channel created.
