Patent CA-2269954-A1 (CA)
Title: Low pressure actuator
Inventor: PEREZ JOSE
IPC: F15B15/10
Filed: 1999-04-26
Abstract: The device comprises an elongated elastomer tube, sealed tightly by clamps at each end against disk shaped end pieces, the one end disk fixed and the other sliding, axially to the other disk, on restraining rods. An orifice in the fixed disk permits the injection of pneumatic pressure causing the expansion of the elastomer tube. Surrounding the elastomer tube is a restraining tube of woven fabric or other material which will not expand radially. The second tube is also affixed to each end disk by the clamps and has sufficient length to reach between the two disks when the disks are at their farthest distance from each other. When the disks are not fully distanced from each other, the outer tube crumples axially but not radially. Action commences when the disks are closest to each other. Controlled pneumatic pressure injected through the orifice causes expansion of the elastomer tube. The outer restraining tube causes all force to be directed to move the sliding disk away from the fixed disk on the guiding mechanism, thus creating an axial force.

Abstract: The invention in the main relates to items of jewellery, wherein gem stones are set in malleable material such as gold sheets to form lockets and the like. Setting heretofore has been by hand by skilled craftsmen, who can work only in relatively thick material, which increases the cost of the jewellery.  In the inventive method, much thinner sheet material is pressed to form a recess for the gem, and projections around the recess. The stone is placed in the recess and the assembly is pressed in a jig, which causes the projections to be deformed and form claws over the stone edges setting it in the sheet.  The invention also provides an item of jewellery, and a machine for carrying out the method.

Title: Production of transgenic poinsettia
Inventor: VAN ECK JOYCE
IPC: C12N15/82
Filed: 2000-01-07
Abstract: Since its introduction into North America over 170 years ago, the poinsettia has become a major ornamental potted plant, and is an important component of the U.S.  floral industry. Susceptibility to insect pests and diseases caused by pathogens remains a problem for poinsettia production, even under greenhouse conditions. While chemical treatment can control certain insect pests and disease pathogens, such treatment can also have an adverse erect upon poinsettias. The methods described herein provide a means to genetically engineer transgenic poinsettia that express macromolecules capable of protecting the plant against the insects and pathogens. The production of transgenic plants can also be used to enhance the commercial value of poinsettia by controlling characteristics such as flower color.

Patent CA-2298119-A1 (CA)
Inventor: CRAGG ANDREW H
IPC: A61J15/00
Filed: 2000-02-08
Abstract: A system or assembly for anchoring percutaneous devices, e.g., tubes or catheters or leads, extending percutaneously through a percutaneous passageway from the skin of a patient to a subcutaneous location or body cavity or tract or lumen from movement further into the body or retraction out of the body. An implantable anchor comprising an anchor body and a tensioning filament is inserted through the percutaneous passageway and deployed subcutaneously with the anchor body in engagement with body tissue in a manner that inhibits it from being retracted through the passageway. The tensioning filament extends from the anchor body and alongside the percutaneous device body through the percutaneous passageway and tension is applied to it to draw the deployed anchor against subcutaneous body tissue and toward the patients skin.  The tensioning filament is coupled with an attachment mechanism secured against the percutaneous device body outside the patient's skin at a location adjacent to the patient's skin. The assembly of the deployed anchor within the patient's body with the external attachment mechanism inhibits advancement or retraction of the percutaneous device body through the percutaneous passageway. When use of the percutaneous device is to be discontinued, the tensioning filament can be severed outside the skin, to release and retract the percutaneous device and attachment mechanism as a unit from the percutaneous passageway, releasing tension on the anchor body. The retraction filament is then retracted, causing the anchor body of the anchor to pivot into axial alignment with the percutaneous passageway, and the anchor body can then simply be pulled out through the percutaneous passageway. The percutaneous device is preferably a gastrostomy or jejunostomy or gastro-jejunal catheter having a catheter body lumen and a disposable inner liner fitted therein and engaging the anchor body during insertion through the percutaneous passageway and retractable to release the anchor within the patient's stomach or small intestine.

Filed: 2000-03-14
Abstract: A portable pipe irrigation system that is used primarily for temporary drip and sprinkler installations includes a unique trailer that comprises a platform which simplifies installation and removal of the irrigation system. The trailer is either self propelled or pulled by a tractor. A central portion of the trailer is of a sufficient length to accommodate pipe of various lengths and cross sections. The central portion of the trailer is referred to herein as the magazine. A  work platform is located at either end of the magazine. These platforms allow workers to manipulate the pipe in the magazine and load the pipe into one of two installation chutes. The platforms also serve to store previously staged piping components. Catwalks are located on one or both sides of the magazine. If pipe is being installed from one side of the magazine, then only one catwalk is provided; if pipe is being installed from both sides of the magazine, then two catwalks are provided. The catwalks allow workers to walk safely and freely along the side of the magazine. The workers are responsible for assembling the pipe sections and placing them in position to be installed in the field (or to disassemble the pipe when it is removed from the field). Two chutes or channels are located on the platform at a comfortable work level, e.g. about waist level.   The chutes or channels extend the length of the platform. A primary chute is located closest to the magazine and is fitted with a fixed stop on the front end and a pushing lever on the rear end. A secondary chute is provided for final assembly of the pipe sections. The secondary chute has a lever of a much longer radius that travels along the length of the chute. The two chutes define work areas where the pipe sections are assembled or disassembled. At the rear of the trailer/platform are outriggers that assist in the accurate placement of pipe in the field.

Abstract: A surgical visualization and moisturizing device providing improved visualization and moisturizing of a surgical site such as an anastomosis. The device of the present invention is provided with a plurality of small flexible lumens extending through and terminating distal of a gas flow port to thoroughly mix and moisture the gas flow with a saline solution. Each of the plurality of flexible lumens, preferably forming a ribbon, are separated from one another slightly at the distal tip to permit vibration due to the gas flow exiting about and past each of the saline lumens. This spacing further facilitates uniform moisturizing of the gas flow. The distal ends of the saline lumens extend beyond the tip of the device such that the pressure of the gas flow approaches atmospheric pressure, whereby gas flow will not go against the head pressure of the saline bag. This eliminates the need for a pressure cuff on the saline bag. The present invention further minimizes dripping at the distal tip, further improving visualization of an anastomosis site for the surgeon.

Title: Multi-channel moving target radar detection and imaging apparatus and method
Inventor: WEBER PETER THOMAS
IPC: G01S13/87
Filed: 2000-04-07
Abstract: A radar detection and imaging system provides for the simultaneous imaging of the stationary objects on the earth's surface and the detection and imaging of moving targets. The radar system includes at least one transmitting aperture and a plurality of receiving apertures that are simultaneously operated in a synthetic aperture radar (SAR) mode caused by the motion of the satellite or airborne platform on which they are mounted. Each receiving aperture is connected to its own coherent receiver and the digitized signals from all receivers are processed to image both stationary clutter and moving targets. The system employs space- time adaptive processing (STAP) algorithms to better compensate for channel mismatches, better suppress stationary clutter, and to suppress mainbeam jamming. Moving target detection and estimation modules are also included and are their performance is improved as a result of the STAP algorithms. The system also employs SAR processing algorithms to create high- resolution images of stationary objects, and to image moving targets. The SAR and STAP algorithms are uniquely integrated in the radar signal processor (RSP) to provide improved performance while reducing the computational requirements, facilitating real-time implementation.

Abstract: A multiplexer device (42) for multiplexing and demultiplexing signals between a low-speed network including 28 DSX-1 signals (22) and a relatively higher speed network including a DS-3 signal (24). The multiplexer device (42) includes 7 quad DSX-1 cards and 1 spare card. The spare card is connected to the other 7 DSX-1 cards in a fashion that allows the spare card to automatically be switched in for one of the DSX-1 cards or to allow interface electronics on the spare card to replace selected ones of the interface electronics on various different DSX-1 cards simultaneously. A pair of controller cards, a primary card and a secondary card, perform the M1-3 multiplexing and demultiplexing and the DS-3 framing and transceiving. The controller cards can be selected or deselected by distributed logic in a sufficiently short time period so that alarms are not set off and so the transition is hitless. This is accomplished by electronically enabling and disabling the transceiver.
