Abstract: A system and method for increasing the robustness of an optical ring network having a plurality of ring nodes. Optical data traffic is transmitted between a plurality of ring nodes (112, 114, 116, 118, 120, 122) via optical links (154, 158). A first optical cross connect switch (104) and a second optical cross connect switch (106) are coupled to an alternate network (150, 152, 154). The first optical cross connect switch is coupled to a first ring node.  When a failure is detected in the first optical link, then the first optical cross connect switch couples the first ring node to an alternate path (152) of the alternate network, and the second optical cross connects switch couples the second ring node to the alternate path such that optical data traffic is transmitted between the first ring node and the second ring node via the alternate path.

Patent CA-2322116-A1 (CA)
Inventor: HEIM DANIEL MARC
IPC: A01F7/06
Filed: 2000-10-03
Abstract: A rotary combine is equipped with a rotor that has a separating portion having at least one ramp segment mounted to the rotor. The ramp segments provide an inclined face that directs the grain radially outward as the ramp segments move through the crop material. The ramp segments are intermixed with tines on the separator section of the rotor. The ramp segments provide a face that is trapezoidal in shape, having inwardly inclined front and rear edges so that the radially distal edge of the face is shorter than the proximal edge of the face. The trapezoidal shape of the ramp segments assists the ramp segments in shedding crop material and thereby preventing the crop material from becoming entangled thereon.

Title: System and methods for analyzing biomolecular sequences
Inventor: HILLMAN JENNIFER L
IPC: G16B30/20
Filed: 1999-03-25
Abstract: Polymer sequences are assembled into bins. A first number of bins are populated with polymer sequences. The polymer sequences in each bin are assembled into one or more consensus sequences representative of the polymer sequences of the bin. The consensus sequences of the bins are compared to determine relationships, if any, between the consensus sequences of the bins.  The bins are modified based on the relationships between the consensus sequences of the bins. The polymer sequences are reassembled in the modified bins to generate one or more modified consensus sequences for each bin representative of the modified bins. In another aspect of the invention, sequence similarities and dissimilarities are analyzed in a set of polymer sequences. Pairwise alignment data is generated for pairs of the polymer sequences. The pairwise alignment data defines regions of similarity between the pairs of polymer sequences with boundaries. Additional boundaries in particular polymer sequences are determined by applying at least one boundary from at least one pairwise alignment for one pair of polymer sequences to at least one other pairwise alignment for another pair of polymer sequences including one of the particular polymer sequences. Additional regions of similarity are generated based on the boundaries.

Title: Roller group
Inventor: TENELSEN JULIEN
IPC: D21G1/00
Filed: 1999-06-28
Abstract: In a group of rolls for a calender for processing material webs, comprising at least two rolls each having a roll body made of a cast or forged iron material, at least one of the roll bodies consists of chilled cast iron or shell-chilled cast iron. One or more rolls may have a cover of a resilient material, such as a polymeric plastic. Although it is possible for the outer diameters of the rolls to differ, the sag of the rolls when they are supported only in their rolling-contact bearings is substantially equal. In order to produce appropriate rolls, following the essential machining steps of the roll bodies, that is to say, for example, following casting, following preliminary turning, following preliminary boring and, if appropriate, following the introduction of peripheral bores, the actual mean modulus of elasticity of the entire roll body is measured and, as a function of this, in particular the inner diameters of the central bores are produced. In addition, methods for influencing the sag of the rolls in a deliberate way, by selecting appropriate materials, the relationships of material structures in the roll body or by means of the deliberate introduction of ballast into the central bore or else into separate peripheral bores in the roll bodies, are described.

Abstract: The invention relates to a slotted closing valve for openings of containers or the like comprising a membrane part (2) which is made of a flexible material  and which contains at least one unidirectionally aligned slotted outlet opening (5). The inventive slotted closing valve also comprises a base part (1) which surrounds the membrane part on the outer periphery thereof and whi ch is connected to said membrane part. The outlet opening is held in a closing position due to the elastic property of the material. However, it can be moved, under a defined differential overpressure which acts upon one side of  the membrane part, against the pretensioning force of the elastic material into an opening position. A peripheral wall area (6) of the base part and an  adjacent wall area (3) of the membrane part form an acute angle .alpha. together. In the membrane wall area, at least one additional slotted continuous opening (8) is provided in the vicinity of the base part. Said additional slotted continuous opening is aligned in an essentially periphera l manner, is held in a closing position due to the elastic property of the material, and can be moved into a releasing position under a differential lo w pressure exerted on the membrane part by the side that can be subjected to t he action of the defined differential overpressure. As a result, the valve enables an equalization of pressure between the inner and the outer surroundings of a container, thus having a favorable effect on the restoring  ability of the container after the container wall has been compressed by han d in order to empty the contents of the container.

Title: Arrayed waveguide grating and multiplexer/demultiplexer system and multiplexer/demultiplexer device using thereof
Inventor: UEDA TETSUJI
IPC: G02B6/293
Filed: 2001-06-27
Abstract: An arrayed waveguide grating of the present invention comprises a first circuit A and a second circuit B. When multiplexed lights are inputted from a fiber array which is connected to input/output waveguides at multiplex side, the multiplexed lights propagate through the input/output waveguides at multiplex side, and are outputted to a slab waveguides at multiplex side. The outputted multiplexed lights are spread in a radial pattern and inputted to an arrayed waveguide group by equally segmented optical power, and then outputted to slab waveguides at demultiplex side being provided with phase shift at the fixed difference in length. Demultiplexed lights outputted to the core of input/output waveguides at demultiplex side, generating a multiple beam diffraction interference at the slab waveguides at demultiplex side, are outputted into an optical fiber of a gape fiber by the fiber array.      Consequently, miniaturization and lowering the price are realized, and there will be less limitation in the mounting space and the mounting position.

IPC: F04B39/00
Filed: 2000-01-06
Abstract: Variable displacement pistons are produced wherein hollow piston bodies are integrally formed with associated actuator arms to ensure proper alignment of the bodies and rods. The process utilizes a two-axis press (40) to first form a pair of actuator arms (14', 14'') by working a blank of metallic material along a first axis (30) between opposing members (42, 44) of a die assembly.  With the die assembly still closed after formation of the actuator arms (14', 14''), a pair of hollow piston bodies (12', 12'') are formed by extruding the remainder of the blank of metallic material along a second axis (32). The hollow piston bodies (12', 12'') are axially aligned and integrally formed with respective ones of the actuator arms (14', 14''). A piston head is welded to the end of each hollow piston body which is then machined. By separating the actuator arms from one another, a pair of variable displacement compressor pistons having hollow piston bodies axially aligned and integrally formed with respective actuator arms are thus formed.
