Patent CA-2486207-A1 (CA)
Title: Lift station and method
Inventor: BRATTEN JACK R
IPC: B23Q11/10
Filed: 2004-10-28
Abstract: A lift station for raising the level of an open channel flow of liquid by sweeping blades momuted to a rotated wheel into the liquid flow after entering a housing to sweep the liquid up and back along a housing interior wall and over a weir edge located well above the level of the open channel flow stream, The flow stream is caused to descend as it enters the housing through a drop to increase the flaw velocity to a degree sufficient to offset the impeding effect on upstream flow of the encounter of the flow with the rotating blades.  Roller bearings are mounted to the inside of the housing to side walls to support the bladed wheel and are packed with a solid lubricant to insure a long service life despite being exposed to the liquid and debris entrained therein. A reverse rotation device positively prevents a backwards rotation of the wheel to prevent damage to the blades. The wheel is driven by a orator mounted in a housing tray affixed to one side wall driving a drive shaft penetrating the side wall.  The housing tray collects any liquid leaking past the shaft and has a sloping bottom directing liquid back towards a drain hole in the housing side wall.

Abstract: An anastomosis device formed from a Shape Memory Alloy (SME) wire that is annealed into a tight coil (e.g., flat coil, helical coil, cylindrical coil) that is subsequently substantially straightened (e.g., straight, longitudinally stretched spring-like shape) for being constrained within an elongate member of an anastomosis introduces instrument. After positioning and holding two tissue walls of adjacent lumens into apposition with a distally presented grasper of the instrument, a piercing tip of the anastomosis device is dispensed and inserted through the tissue walls before being allowed to relax to its tight coil shape, thereby forming the anastomosis attachment. The anastomosis device is released from the anastomosis introduces instrument, such as by fully dispensing its proximal end. Thereby, efficient single lumen anastomosis of gastrointestinal, bilatory, or other vessels may be achieved with a minimum of laparoscopic punctures, or perhaps performed fully as an endoscopic procedure.

Abstract: One embodiment of the present invention provides a system characterizes a document with respect to clusters of conceptually related words. Upon receiving a document containing a set of words, the system selects "candidate clusters" of conceptually related words that are related to the set of words (Figure 22, 2202). These candidate clusters are selected using a model that explains how sets of words are generated from clusters of conceptually related words (Figure 22, 2204). Next, the system constructs a set of components to characterize the document, wherein the set of components includes components for candidate clusters (Figure 22, 2206). Each component in the set of components indicates a degree to which a corresponding candidate cluster is related to the set of words (Figure 22, 2208).

Patent CA-2516167-A1 (CA)
Inventor: NEWMAN PETER ALFRED
IPC: G11B20/00
Filed: 2004-02-19
Abstract: It is proposed to copy protect data files for transmission by incorporating DSV data patterns, that is, data patterns which are difficult to encode without causing DSV problems, in the data files. The data in five audio streams and two video streams is placed, by way of encoders (10) and a multiplexer (12) into a stream of blocks of encoded data in the MPEG file format (14). In this format, blocks of video data V are arranged alternately with blocks of audio data A and padding stream blocks P. DSV data patterns (16) are incorporated into the MPEG file (14) by way of an encoder (18) to produce the copy protected data file (15). The DSV data patterns (16) are incorporated into locations within the MPEG file which have no data content such as padding stream blocks P and/or into unused audio data blocks A. The DSV data patterns incorporated within the data blocks fed either to a monitor or to a reproduction system will not interfere with the reproduction such that unfettered access is provided to the transmitted information. However, a CD or DVD writer will generally be caused to write a disc which, when read, will result in a reader returning corrupted data or information signalling a read error. Thus, the data in the MPEG file (14) has been copy protected.
