Patent CA-2349260-A1 (CA)
Inventor: MILLER MARK S
IPC: G01S17/87
Filed: 1999-11-10
Abstract: A three-axis, non-scanning, self-referenced laser air data sensing system (1 0) comprises a support (12) having three separate laser diodes (56A-56C) providing beams (22A-22C) of coherent light, which beams (22A-22C) are directed toward separate beam expander mirrors (24A-24C). The expander mirro rs (24A-24C) reflect an expanding beam (26A-26C) back toward a focusing mirror (28) that focuses the beams along three diverging axes (30A-30C) at known angles to each other at three separate locations in space. The focused beams  (30A-30C) form small detection cell regions (32A-32C) through which particle s in the fluid pass and reflect light. The reflected light is received back along the same paths (30A-30B; 26A-26C; 22A-22C) as the transmission of the source light, and is directed back toward detectors (70A-70C) on the support  (12). The reflected light undergoes a Doppler shift, and this reflected ligh t is combined with a reference signal (66A-66C) tapped from one of the other o f the three coherent light sources (56A-56C) for heterodyning the signals for determining the Doppler shift and thus the relative velocity.

Inventor: BALL PETER
IPC: C08F6/00
Filed: 1999-10-14
Abstract: The invention relates to a method for reducing odour emissions of aqueous aromatic vinyl-1,3-diene-copolymer dispersions which have been stabilised with a protective colloid. The invention also relates to redispersion powders obtained by drying said dispersions. This is achieved by emulsion polymerisation of a mixture containing at least one aromatic vinyl and at least one 1,3-diene in the presence of one or more protective colloids and by optionally drying the polymer dispersion obtained thereby. The invention is characterised in that 0.01 to 15.0 wt. % of one or more monomers selected from the group of branched or unbranched alkyl esters containing 1 to 8 carbon atoms in the alkyl radical of monounsaturated mono- or dicarboxylic acids are added at the end of the polymerisation when the total content of the aqueous polymer dispersion containing free monomers ranges from > 0 to <= 20 wt. %, whereby the given wt. % refers to the polymer content of the dispersion.

Abstract: An orthopaedic method and anchor assemblies for anchoring a linkage such as a rod or cable used for fixation or reduction. One assembly includes an anchor plate and a slotted anchor bolt that captures the plate in a one-piece assembly for convenient installation. The base of the anchor bolt lies below the plate, and a cap or nut tightens down to secure a linking member, e.g., a rod or cable, in the slot, simultaneously clamping the bolt to fix both its position and its orientation on the plate. One occipital plate has lateral arms that hold the anchor bolts, and a Y-shaped embodiment is mounted in an inverted orientation to position the anchor bolts well down in soft tissue for more effective wound closure. A cable connector is used together with an anchor plate, vertebra anchor screws and fixation rods to secure ends of a cable at the level of one or more vertebrae, providing a versatile and highly stable system for alignment, fixation and fusing of the cervical and thoracic spine. The cable connectors have an open-sided channel that fits onto and securely clamps to an already-positioned fixation rod, with an eyelet or other structure providing a rigid and fixed securing point for a cable that is threaded about the vertebrae under tension. Methods of fixation are described.

Title: Apparatus for the purification of liquids
Inventor: REMIZOV ALEKSANDR DMITRIEVICH
IPC: B01D24/16
Filed: 2001-08-23
Abstract: The invention pertains to apparatus for the separation of liquid and heterogenic phases and is concerned particularly with apparatus for the purification of liquids which can be used in communal, agricultural and industrial applications. The apparatus provides containment of backwashing liquid within the apparatus with subsequent purification of backwashing liquid and supply of purified liquid to the consumer. The apparatus comprises a filter 1 with a filtering element 2 made of, for example, floating bead material (expanded polystyrene with bead size 0.5-3.0 mm) and a filtrate discharge pipe 5. A pipe-type settler 6 is positioned below the filter 1, and the upper ends of settler pipes 7 are connected to a partition 8 which separates the settler from the filter. In the upper part of settler 6, an interpipe working space is formed and is connected to the filter through pipes 7. Pipe 4 for the supply of liquid to be purified is connected to filter 1 under floating bead media 2. A source of compressed gas (with the possibility of providing a pulsed supply) and a device for the discharge of compressed gas to the atmosphere are connected to the upper part of the settler 6 next to the partition 8. In the process of contaminated liquid purification, compressed gas, for example air, arrives from its source in the upper part of settler 6 where it accumulates. During the backwashing of the filter 1, the accumulated gas is discharged from the upper part of the settler 6 through the pipe 15 into the atmosphere. The gas becomes replaced with backwashing liquid arriving from the filter 1. In the process of facility operation, the backwashing liquid is expelled from the upper part of settler 6 by the gas arriving from the compressed gas source, becomes clarified in the pipes 7 of the settler 6 and further purified in the filter 1, and then is supplied to the consumer. If the filtration cycle shortens to less than 6 hours, then a pulsed supply of compressed gas is provided. The pulses of gas pressure transform into pulses in the liquid flow, resulting in a short-term acceleration of liquid filtration through the floating bead material 2, and the disengagement of admixtures and their more deep penetration into the floating bead meaterial 2. This leads to a prolongation of the filtration cycle and reduction in the number of backwashes over a certain period of time, and subsequently to a reduction in non-productive use of liquid.

Title: Intelligent routing for effective utilization of network signaling resources
Inventor: MCALLISTER SHAWN
IPC: H04L45/28
Filed: 2001-09-14
Abstract: In source routed or hop-by-hop routed protocol communication networks, when congestion is detected at a certain network element, a notification message is sent to nodes. The nodes keep track of congestion condition and generally have knowledge of the congestion, thereby allowing them to make more intelligent routing decisions, i.e., rate controlling messages, routing traffic around congestion, regulating admission at the edge of the network. The intelligent routing decision is based on the congestion condition indicated by a restriction level which is periodically and dynamically updated.

Abstract: A method and system for transferring money from a sender to a receiver utilizing a computer network such as the Internet (12). The sender (16) visits a web site and identifies, to the server (34) over the Internet, the receiver (30), an e-mail address to the receiver (18), an amount of money to be transferred, and a withdraw account from which money is to be transferred. The withdraw account can be a checking account (56), a checking account secured by a credit card account (24), or a credit card account (26). Money is transferred from the withdraw account and preferably deposited into a holding account. The server automatically sends e-mail to a receiver, over the Internet, to inform the receiver that the sender has transferred money and to request the receiver to visit the web site of the server to receive money. The receiver visits the web site of the server in response to the e-mail and identifies a deposit account to which money is to be transferred.
