Abstract: An electrophoretic display element includes a capsule having a first, larger surface and a second, smaller surface. The capsule contains a suspending fluid and at least one particle dispersed within said suspending fluid. Application of a first electrical field causes the particle or particles to migrate towards the first, larger surface of the capsule, causing it to take on the visual appearance of the particles. Application of a second electrical field causes the particle or particles to migrate towards the second, smaller surface, allowing the capsule to take on the visual appearance of the dispersing fluid or of a substrate or electrode positioned behind the display element. Displays may be fabricated from multiple display elements arranged on a substrate.

Title: Woven stent/graft structure
Inventor: GREENHALGH E SKOTT
IPC: A61F2/90
Filed: 1999-08-04
Abstract: A combined stent/graft structure for repair of a body tube in a living body.  The structure includes a textile graft adapted to enhance fluid integrity of the body tube and a stent expandable between a first position permitting easy insertion of the stent into the body tube and a second position wherein the stent presses securely against the inside surface of the body tube. The stent includes a first elongate wire-shaped stent member with both a stent member global axis and a stent member local axis, and is integrally secured to the graft by at least one graft yarn of which the graft is formed. Substantial portions of the first stent member global axis form a non-orthogonal angle with the graft main portion axis when projected into a plane containing the graft main portion axis. This permits repeatable, reliable manufacturing and allows the stent member to extend over substantially the whole length of the structure to provide uniform flexural properties and support throughout. Embodiments wherein the first stent member global axis forms an orthogonal angle with the graft main portion axis are also contemplated. A method of forming a textile with an undulating wire is also provided. Further, a woven textile is also part of the invention as is a method of manufacturing such a woven textile, which can be used to produce stent/graft structures according to the invention. Inventive weaving shuttles suitable for manufacturing structures in accordance with the invention are also set forth. Methods utilizing shape-memory stent members for ease in manufacturing are also disclosed.

Title: Quality control system for monitoring and control of contaminants in recycled plastics
Inventor: TACITO LOUIS D
IPC: B29B17/02
Filed: 1999-08-17
Abstract: An apparatus and process for continuously discriminating between a contaminated plastic material containing trapped volatile contaminants and plastic material which contains an acceptable threshold of contaminants comprising first supplying a continuous source of plastic material wherein the plastic material contains trapped volatile contaminants and feeding a sample of the plastic material preferably to the input section of an auger conveyor (18).

Title: Lubricating system for internal combustion engine
Inventor: ITO KATSUHIKO
IPC: F01M1/16
Filed: 2001-04-30
Abstract: An oil passage extending from an oil pump to a discharge port in an internal combustion engine is, at its halfway point, branched into at least two oil passages, for example, a first oil passage 44 and a second oil passage 45; and one of the at least two branched oil passages, for example, the second oil passage 45 is provided with a restricting portion configured as a first orifice 83 for restricting a flow amount of oil by reducing a diameter of the first orifice 83, and a bypass valve 92 which acts, when a hydraulic pressure in the second oil passage 45 exceeds a specific value, to bypass the first orifice 83 so as to increase the flow rate of oil. It is possible to increase the hydraulic pressure at the time of low speed rotation up to a necessary pressure only by providing the restricting portion, without enhancing the performance of the oil pump. Accordingly, it is possible to suppress the increase in weight and cost of the lubricating system as compared with the prior art lubricating system in which the performance of the oil pump is enhanced, and since it is not required to increase the rotational speed of the oil pump, it is possible to prevent the loss in output of the internal combustion engine due to the increased friction of the oil pump. Further, it is possible to prevent excess increase in pressure of the oil passage by the effect of the bypass valve.
