Patent CA-2263922-A1 (CA)
Inventor: FUKUI YOSHIHIRO
IPC: E01B13/00

Abstract: The present invention relates to a steel sleeper which is capable of preventing, to a great extent, subsidence and buckling and is less likely to change in shape under an excessive load from the rails. The steel sleeper has a flat top flange and a flat bottom flange, while a vertical web is formed continuously in the longitudinal direction of the sleeper to connect the top flange and the bottom flange at the centers of both flanges in the direction of width thereof. The steel sleeper has a substantially I-shaped cross section in the direction of width thereof, with both end faces of the sleepers in the longitudinal direction thereof being capped with buckling preventing plates. The spaces surrounded by the flat top flange, the flat bottom flange, the vertical web, and the buckling preventing plates are open to the outside on the side face thereof. The load from the rails is transmitted via both the top flange and the bottom flange to the ballast.

Abstract: A liquid inflatable tube, intended to be filled with water, and when joined linearly as in end-to-end or vertically as in a pyramid shape, or both, form a barrier system for containing or diverting water from creeks, streams, floods, and other applications where a temporary dike system is required. The barrier length may be increased indefinitely with the addition of more tubes joined to the end of the preceding tube. The height of the barrier may be increased through the use of larger diameter tubes and by adding additional tubes to the pyramid.   The tubes are constructed of a flexible woven plastic fabric. The tubes may be filled and alternatively, drained of water through the use of ports which are permanently attached to the tube.   The weight of the water keeps the tubes in place against external forces such as water flow from creeks and streams, and both water flow and wave action caused by floods and wind. A series of grommets installed in a "ground sheet" of woven plastic flexible material permanently affixed to the bottom of the tube may be used to drive stakes into the ground enabling the barrier to withstand greater water flow and velocity without failure. ability.   The end-to-end connection is accomplished through the insertion of one end of a tube into a skirt permanently affixed to the preceding tube prior to filling with water.  Upon filling, weight and friction hold the tubes in place. A latching system enhances the strength of the end-to-end connection.   Where tubes are stacked in a pyramid shape to achieve greater height, another latching system is employed to provide greater structural integrity than if the tubes used only the weight of water to keep them in place. The latching system consists of a row of grommets on each side of the tube which are connected to the ground sheet of the tube above it, through the grommets provided.   Various types of connectors may be used such as "S" hooks, quick links, plastic ties and and other devices may be used to latch tubes together, vertically and horizontally.

Abstract: A polyolefin plaque is produced by hot compaction of an assembly of melt spun oriented fibres. It has been found that good compaction can be achieved at relatively low compaction pressures, less than 10 MPa. Compaction can be carried out in an autoclave, rather than in a hot compaction press, and the mechanical properties of plaques so produced range from good to excellent.

Title: Methods for objectification of subjective classifications
Inventor: MEYROWITSCH JAN
IPC: G06K9/00
Filed: 1997-11-14
Abstract: The method is based on consensus analyses of classifications at the object level carried out by learning systems. To determine persons or groups of persons ability to analyse details, e.g. in visual objects, digitised images of the objects are feed into a computer, where each image is assigned a number of characteristics,N out of Q possible. Some of the characteristics in the images are being selected, after which a person is set to identify the images by determination of the characteristics. The same image in a series of images is presented for the person several times, and if the person is capable to distinguish the images from each other, and furthermore reach the same results with the same images, then the person possess good abilities for type determination of reference signals, e.g. in form of images. The invention is suitable to identify persons, who are gifted for analysis of e.g. biological samples, such as images samples of semen samples, cancer cells, etc.

IPC: H04N1/195
Filed: 1999-07-07
Abstract: A computer-stored raster image is plotted field-wise a manner analogous to the structure of a chessboard by means of an exposure head which is continuously displaceable relative to a light-sensitive record carrier and containing a light modulator. Through the sustained relative movement the plotting would turn out to be undesirably blurred in the case of a longer exposure period. This blurred effect is compensated by the displacement of a lens determining a focussing scale and which is positioned between record carrier and exposure head. Prior to plotting of a new field the displaced lens is retracted into a relative starting position for the new field so as to be displaced compensatively during the next exposure period. This process allows almost continuous exposure with high plotting energy, particularly through the usage of mercury arc lamps and thus also direct exposure of photo-resist material, such as that used in the manufacture of printed circuit boards.

Title: Method and device for control and compatible delivery of digitally compressed visual data in a heterogeneous communication network
Inventor: BANHAM MARK R
IPC: H04N19/00
Filed: 2000-02-04
Abstract: A method and apparatus automatically manipulates a digitally compressed video bitstream such that the result is compatible with different bandwidth and error resilience requirements at a receiving point in a heterogeneous communication network. The method and device provide for analysis of bitstream header information to determine its relevant coding syntax parameters. Feedback from the receiving point on the network is then used to identify error robustness requirements for an intermediate bitstream. The bitstream is then manipulated by an error robustness regulator to achieve error protection in the network. The bitrate requirements of the network establish a selection of relevant and irrelevant bits from the bitstream The present method and device include identification of irrelevant and low priority video bits; intentional introduction of packet losses to reduce bitrate while maintaining visual quality; use of replacement tags for irrelevant and low priority components of the bitstream for compatible decoding by a wide array of decoders; and insertion of resynchronization tags and translation of predictively coded video packet bits for the improvement of error resilience.
