Title: Method and apparatus for classifying batches of wood chips or the like
Inventor: COUTURIER JEAN-PIERRE
IPC: G01N21/55
Filed: 1999-01-22
Abstract: A method and apparatus for classifying batches of wood chips or the like according to light reflection characteristics provide optimal use of darker wood chips in pulp and paper processes. According to a preferred embodiment, light produced by a set of illumination sources is evenly directed onto superficial wood chips of an inspected batch portion transported on a conveyor while being inspected by a camera disposed over the conveyor. The superficial wood chips presenting light reflection characteristics being substantially representative of the wood chips of the inspected batch, reflected light is sensed by the camera to produce electrical signals representing reflection intensity values for the wood chips of the batch portion. From the electrical signals produced, image processing is performed to provide global reflection intensity data for the inspected batch, which are then compared with reference reflection intensity data to provide classification of the inspected wood chips batch into proper wood chips grade according to its light reflection characteristics.

Title: Personal flotation device construction method
Inventor: WAGNER STEVEN G
IPC: B63C9/115
Filed: 2001-10-09
Abstract: A personal flotation device (PFD) with flotation foam is disclosed. A soft PFD, or a life jacket, is made up of a number of individual pockets in which flotation foam is enclosed to provide buoyancy. An additional layer of soft foam is fastened between the flotation foam and the material forming one side of each individual pocket to create a rounded edge that covers the harder edges of the flotation foam that cause user discomfort. To manufacture the soft PFD, two layers of material are first fastened to each other at their edges to form at least one open pocket. A soft foam layer is fastened by its edges to the exterior of one or both of the material layers, or simultaneously as the two material layers are fastened together. The open pocket is subsequently turned inside out to form an inverted pocket. This causes the material layer with the fastened soft foam layer to round out. Flotation foam is then inserted into the inverted pocket, which is subsequently closed.

Title: Covered stent with encapsulated ends
Inventor: KIRCHHOFF THOMAS
IPC: A61F2/06
Filed: 2000-02-02
Abstract: A portion of a covered stent is encapsulated with ePTFE, so that the unencapsulated portion, which is covered by a single ePTFE covering, of the stent unimpaired flexibility. One surface of the stem, either the luminal or abluminal surface, is covered by a single continuous layer of ePTFE, while limited regions, preferably near the ends of the stent, of the other surface are also covered by ePTFE. The regions covered by ePTFE on both surfaces become encapsulated when the ePTFE of one layer becomes bonded to second layer. By leaving a middle region of the stent unencapsulated, the stent retains flexibility similar to a bare stent, thereby reducing the loading and deployment forces.

Title: Method of controlling the flow in a flow system
Inventor: BARHOLM-HANSEN CLAUS
IPC: G01N33/48
Filed: 2001-02-13
Abstract: With a method of controlling the flow in a flow system where a liquid flow contains a particle concentration, the liquid flow is surrounded by a carrie r liquid. The liquid flow and carrier liquid are led into a central channel in  which there is provided an observation area (4) where measurements of the liquid flow are effected. The result of the measurements are used to lead th e liquid flow into one of several channels, in that control liquids are introduced into the liquid flow before this reaches the channels, the contro l liquids being derived from a capillary pump structure which pumps on the bas is of an electro-kinetic effect, e.g. an electro-osmotic effect. In a preferred  embodiment, the pump structure consists of two capillary structures, to each  of which an electrical field can be applied. Depending on the strength of th e field, the amount of control liquid will be able to be controlled so that th e liquid flow with the particle concentration can be led to one of two channel s. In a second embodiment, the pump structure consists of one capillary structure. The liquids can with advantage be controlled in such a manner tha t when the amount of liquid in the one capillary structure is increased, the amount of liquid in the second capillary structure will thus be reduced correspondingly. The advantage of the invention is first and foremost that t he pumping is carried out without the use of mechanical pumping arrangements, which are relatively expensive. Moreover, a better retention of the flow pattern in the flow system is achieved.
