A technique can be used increase the flow of fluid through the trabecular meshwork. The fluid pulses can be focused, thereby perforating the trabecular meshwork, or applied over a larger area so as to stimulate the trabecular meshwork for improved fluid transport. In addition, the pulses of the irrigating fluid can clean away material, such as iris pigment, that may be blocking or clogging the trabecular meshwork. Such a technique may be practiced using the tip of the present invention and commercially available surgical handpieces.

The invention concerns a method and means for control of traffic on a network by route control. The method and the means are based on functions in a traffic management system. The invention includes control of traffic from a first route, which passes a bottleneck, which can be a part of the network, e g a node or a link, with low capacity relative to the demand of traffic through the node or the link,-to at least another alternative route. That alternative route is separated from the first route at a node upstream of the bottleneck and is routing at least parts of the traffic another road passing the bottleneck of the first route. The method is built on several cooperating method steps and route control can be applied on several different hierarchic levels in the network, locally and more comprehensive. Essential method steps are estimating and controlling traffic margins on selected links and nodes in the network and utilizing those margins at the route control. The invention concerns traffic control of vehicles on a road network as a first hand application. But the method can also be used for other applications, as traffic control of data packets on a communication network.

There is provided a pulsatile blood pump (10) for implantation into a patient. The pulsatile blood pump comprises a substantially tubular body (12) a flexible membrane (14) and a port (16). The substantially tubular body is for replacing a resected portion of a blood vessel of the patient. The substantially tubular body has first and second ends with a blood passageway extending therebetween for the passage of blood. The flexible membrane is attached to the tubular body so as to form a fluid chamber between the flexible membrane and an inner surface of the tubular body. The flexible membrane thereby separates the fluid chamber from the blood passageway. The tubular body comprises the port. The port is arranged to allow fluid to flow into and out of the fluid chamber such that the volume of the fluid chamber increases and the volume of the blood passageway decreases when fluid flows into the fluid chamber via the port, and such that the volume of the fluid chamber decreases and the volume of the blood passageway increases when fluid flows out of the fluid chamber via the port. The blood pump is thereby enabled to pump blood along the blood passageway.

The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. The present invention has a uniquely curved nozzle with a flat flange. Both the curvature of the nozzle and the flat flange promote the accumulation of water within the nozzle so as to build up pressure that then pushes the water out a small outlet hole at a greater rate than does a conventional water return fitting. The outflow from the nozzle then creates a low pressure condition within a mixing chamber. Thus, the low pressure condition draws water in from the swimming pool through various louvers into the mixing chamber where it is mixed with the outflow of water from the nozzle to increase the total amount of water flowing out of the water return fitting of the present invention.

The method for preparing the cross-linking type butadiene-acrylonitrile copolymerizing rubber is adopted to obtain butadiene-acrylonitrile copolymerizing rubber with the structural gel content of between 30 and 90 percent. The processability of the obtained polymer is improved, and the shrinkability of products is small (the shrinkage ratio is below 30 percent).

The high flow water return filling of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. In addition, the present invention has a uniquely curved nozzle that does not extend past the face plate, thus, the nozzle does not extend more than one inch from the swimming pool wall. The outflow from the nozzle creates a low pressure condition within the face plate. Thus, the low pressure condition draws water in from the swimming pool through various gaps into the face plate where it is mixed with the outflow of water from the nozzle to increase the total amount of water flowing out of the water return fitting of the present invention.
