Patent CA-2292660-A1 (CA)
Title: Temperature compensation system for regulating flow through tubing in a pump
Inventor: BRIGGS KENNETH D
IPC: A61M5/00
Filed: 1998-06-10
Abstract: A peristaltic pump is provided with a housing, a pump head in the housing, and a receiving path defined along a housing and pump head for receiving tubing. Two spaced-apart temperature sensors are provided.  One temperature sensor is located adjacent the tubing in a heat conduction path along which heat flows between the sensor and the tubing. The other sensor is located outside of the heat conduction path for sensing ambient temperature. The pump operating speed is adjusted as a function of the sensed temperatures. This accommodates the temperature-dependent rate of recovery of the tubing from its peristaltically deformed configuration to its original configuration.
Patent CA-2295434-A1 (CA)
Inventor: ZHU JIA BEI
IPC: A61D19/00
Filed: 2000-01-10
Abstract: In the production of large scale and high quality in-vitro fertilization of bovine oocytes, the ability to efficiently extract oocytes from bovine ovaries is one of the initial but yet crucial steps of the entire test-tube embryo technology. The quantity of high quality in-vitro fertilization embryos produced is often a product of a high number of viable oocytes that are initially extracted successfully. This present invention enables an increase in the rate and number of oocytes extracted from bovine ovaries that is less labor-intensive and less costly.

Title: Machine for conveying lumber or logs of wood
Inventor: PERREAULT RENE
IPC: B65G29/02
Filed: 2000-02-24
Abstract: A machine is disclosed for conveying wooden piece such as logs of wood and lumber, in wood transformation industries such as sawmills. The wooden pieces are conveyed in a conveying direction from the front towards the back of the frame of the machine. The machine has several conveying shafts rotatably mounted in parallel on the sides of the frame. Each shaft has a rotating axis about which it is driven in rotation in a direction corresponding to the conveying direction. Several toothed circular plates are mounted on each shaft and extend in a plane crossing the axis of rotation of the shafts. The plates of a shaft are designed to be offset with respect to the plates of an adjacent shaft. Each tooth of each plate are spaced apart from an adjacent tooth by a distance which corresponds substantially to the range of diameter of the wooden pieces and defines a space therebetween for receiving at least a portion of a wooden piece. The teeth of the plates mounted on a same shaft disposed in order to be aligned together. In action, the rotation of the conveying shafts are synchronised together in such a way that a wooden piece inserted between two teeth of the conveying plates of a shaft is conveyed in the direction of rotation of this shaft until a tooth of the plates of an adjacent downstream shaft carries the wooden piece. So the wooden piece is transferred to the adjacent shaft and is engaged and carried between two teeth of the plates of the adjacent shaft. Therefore, the adjacent downstream shaft conveys the wooden piece further with respect to the conveying direction. The machine can be designed in order to convey the wooden pieces horizontally or upwardly.

Inventor: HENNES MARK A
IPC: A01C5/06
Filed: 2000-02-29
Abstract: A seed opener attached to a seed drill has a trailing press wheel attached to a press wheel frame. The press wheel frame is pivotally attached to a seed opener frame, which, in turn, is pivotally attached to the seed drill main frame. The angle of attachment between the press wheel frame and the seed opener frame is adjustable to allow the press wheel to be used as a depth gauge for the opener blade or blades. Constant downward pressure is applied to the press wheel frame via a down pressure rod and spring extending between the press wheel frame and the drill frame. The use of down pressure on the press wheel frame allows the press wheel to maintain ground contact, with downward pressure, at all times, even when the opener blade (s) encounter an obstacle, thus improving seed distribution and germination. In addition, by placing downward pressure on the press wheel frame instead of the opener frame, the load on the opener blade (s) is minimized even when they encounter, and ride up and over, a fixed obstacle.

Abstract: A link state advertisement protocol message received from an originating device over an inbound interface is forwarded over the fast path according to a multicast distribution tree using a special multicast address. Specifically, a special multicast address is used for the link state advertisement protocol message. The special multicast address differentiates the link state advertisement protocol message from other protocol messages. A multicast routing protocol is used to establish a multicast distribution tree for distributing link state advertisement protocol messages based upon the special multicast address. The multicast distribution tree determines, among other things, the preferred inbound interface for the link state advertisement protocol message and any outbound interfaces to which the link state advertisement protocol message is to be forwarded. The link state advertisement protocol message is forwarded according to the multicast distribution tree. If the link state advertisement protocol message is received over the preferred inbound interface, then the link state advertisement protocol message is forwarded over the fast path to the outbound interfaces) as indicated by the multicast distribution tree. Otherwise, the link state advertisement protocol message is not forwarded over the fast path. The link state advertisement protocol message continued to be processed and forwarded by the control plane as usual for robustness.

Title: Method and apparatus for covering a stent
Inventor: RICHTER JACOB
IPC: A61F2/90
Filed: 2001-01-15
Abstract: An expandable stent suitable for implantation in a lumen is covered with a biological material. In one embodiment, biological fibers are interwoven to form a stent covering. The fibers are disposed at an angle with respect to the longitudinal axis of the stent so that when the stent is expanded, the angle increases. In another embodiment, a strip of pericardium is helically wound around a supporting stent while the stent is in a compressed state. When the stent is expanded, the strip unwinds, but maintains full coverage of the stent. Interlocking edges may be formed on the strip of pericardium to maintain full coverage of the stent.

IPC: E21B43/12
Filed: 2001-01-15
Abstract: The gas-lift reciprocating pump has two cylinders in one casing cylinder. In one of them is located a piston protected by the quicksilver from the top. Another cylinder is the compression chamber. The gas-lift reciprocating pump has two valves: inlet and outlet valves. The quicksilver doesn't allow the contact of the piston and its cylinder with the solids or sand contained in the well mixture (water-oil-sand and solids). The protecting fluid or quicksilver compresses the well mixture trapped in a chamber of compression allowing the pass through the outlet valve up.    The compressed gas causes the reciprocating movement of the piston. The gas is compressed from the surface by compressor and goes between casing pipe and production pipes. It enters to the cylinder, which contains a piston through the hole and pushes it up. When the gas is releases the piston is going down. The gas is forced to enter in the hole due to seal packer installed between casing pipe and casing cylinder from the bottom.      The contact of the sand with the piston and cylinder in the conventional reciprocating pumps causes the big reductions of service time of the pumps. Therefore the novel of this invention is the increase the pump time service due to use of protecting fluid like the quicksilver. The technical field of this invention is the extraction of oil at the oil fields.
