Patent CA-2198000-A1 (CA)
Inventor: SUSLOV NIKOLAI
IPC: A61B18/00
Filed: 1994-08-29
Abstract: The invention concerns a device to improve the coagulation of moderately or heavily bleeding live human and animal tissue and to form an eschar by means of a plasma jet. The device comprises plasma-generating means consisting of an electrically conductive body (6) which is connected to a positive pole of a basic energy source having a positive potential. The body (6) is formed with a cylindrical channel (17) designed to heat the plasma-generating gas. The channel (17) is formed from a number of sections (8, 9, 10) which are electrically insulated from each other and each one of which is connected to the body (6) via bushes (22). The bushes are concentric with the sections (8, 9, 10) and are electrically insulating. The bushes (22) are formed with channels (19) arranged to conduct cooling liquid to and from the gas-heating channel (17).

Title: A mixer and apparatus for analysing fluid flow
Inventor: PARRY SUSAN JOAN
IPC: B01F5/00
Filed: 1995-09-27
Abstract: A static mixer (22) is provided for one or more fluids flowing in a pipe (108), such as oil, water and gas from an oil well. The mixer (22) comprises an element (112, 114) to divide the flowing fluids into at least two streams within the pipe (108) and to deflect two of the resulting streams so that those streams rotate in opposite senses about axes parallel to the direction of flow of the fluid, the element (112, 114) being shaped so as to maintain movement of the flow in a substantially smooth manner. Apparatus (10) is provided for analysing fluid flow in a pipe (108) comprising at least one radiation source (12, 14) to direct radiation through the flow, and at least one radiation detector (12, 14) positioned to receive from the source or sources radiation which has passed through the flow, the source or sources emitting radiation at least at two different energies. The or each detector provides a signal to a processing unit (20) which is arranged to process the signal to provide a series of chronological values, to group the values by magnitude and to analyse the grouped values, for example, to determine phase fraction, type of flow e.g. slug flow, and flow rate.
Patent CA-2203350-A1 (CA)
Inventor: LUCIANI SABATINO
IPC: H02K15/09
Filed: 1997-04-22
Abstract: A transfer mechanism is operatively disposed between a conveyor for dynamo-electric machine parts (such as electric motor armatures) and apparatus for simultaneously processing a plurality of those parts (e.g., by winding coils of wire on those parts).  The transfer mechanism delivers processed parts to the conveyor and receives unprocessed dynamo-electric machine parts from the conveyor, one at a time in a single alignment position, at least partly concurrent with the processing of other parts.  Loss in production time due to wire breakage at the processing apparatus is reduced by substantially instantaneously controlling the broken wire (e.g., by retracting that wire relative to the associated wire dispenser) while continuing to move the wire dispensers.

Patent CA-2211567-A1 (CA)
Inventor: KELLY PATRICK A
IPC: A61F2/958
Filed: 1996-02-05
Abstract: A catheter such as a balloon dilation catheter (10) useful in endoscopic or other surgical procedures can be rendered kink-resistant by the inclusion of a flexible nitinol wire (24). The nitinol wire (24) has a transition temperature well below the temperature of the body, so that it remains superelastic during use of the catheter (10), and permits the catheter (10) to remain essentially unkinked through acute bends and toms which would unacceptably kink comparable catheters having wires of stainless steel or other materials. The potential for patient injury from the catheter is thereby reduced. The catheter (10) includes a tubular polyurethane catheter shaft (12) having a fluid flow lumen (14) defined therein, and an expandable but nondistending PET balloon (18) connected to the distal end (16) of the shaft (12) in fluid communication with the lumen (14). The catheter (10) also includes a flexible catheter tip (22) on the balloon (18) opposite the catheter shaft (12). The nitinol wire (24) is positioned within at least the catheter balloon (18) and the catheter tip (22), and preferably extends the entire length of the catheter shaft (12) through the shaft flow lumen (14). The longitudinal positions of the nitinol wire (24) and the balloon (18) are fixed relative to one antoher by a radiopaque insert (32) in the distal end (16) of the catheter shaft (12). The nitinol wire (24) preferably includes a tapered portion (28) extending from a location (30) within the balloon (18) to the distal end (26) of the nitinol wire (24) in the flexible catheter tip (22). A conventional female luer hub (38) can be connected to the catheter shaft (12) opposite the balloon (18) and the distal end (16) of the shaft (12).

Patent CA-2227815-A1 (CA)
Title: Apparatus and method for automated visual inspection of objects
IPC: G01N21/88
Filed: 1998-01-23
Abstract: The present invention relates to an apparatus and method for the automated inspection of objects for the presence of visual anomalies. The apparatus includes a first wide angle camera for acquiring an image of the object, a processor for detecting targets and generating target location from the image of the object, a two axis post-objective scanner associated with a high resolution camera for directing target image to the high resolution camera. The scanner provides a mechanism for saccadic emulation in combination with a high resolution video camera, which can be synchronized to the frame rate of the video camera for rapid high resolution examination of an object. The method according to the present invention comprises the steps of: capturing an image of at least a portion of an object; identifying visual anomalies as targets and detecting any targets on the object; generating location data for a detected target; emulating saccadic niovement to selectively capture a high resolution image of a target; and generating an output for analysis. The apparatus and method are particularly suited for the automated detection of defects, in particular parasites, in fish fillets. It is an advantage of the present invention that post-objective scanning permits the camera to remain stationary, while only the mirrors are moved, to acquire high resolution data of substantially only the targets, resulting in increased speed and reduced processing time.
