Patent CA-2326057-A1 (CA)
Inventor: YOON JUN-JIN
IPC: C12N11/08
Filed: 2000-11-15
Abstract: The present invention provides a method for preparing three-dimensional, biodegradable and biocompatible, porous, polymeric scaffolds for tissue engineering, which comprises the steps of: (i) dissolving a polymer in an organic solvent to prepare a polymeric solution; (ii) mixing an effervescent salt in the resulting polymeric solution to give a polymer/salt/organic solvent mixed gel; (iii) removing the organic solvent from the polymer/ salt/ organic solvent mixed gel; and (iv) effervescing the salt in the resulting polymer/salt gel to yield a polymeric scaffold. The scaffold of this invention is so porous and interconnective among pores as to accommodate and culture cells isolated from the tissues to be cultured. The method of this invention has several advantages of: (i) easily shaping the cell culture matrix in desirable forms with the gel and (ii) controlling the pore size and porosity of the three-dimensional porous, polymeric scaffolds by controlling the amount and size of the effervescent salts and the concentration of the acidic aqueous solutions with which the effervescence and leaching-off of the salts are induced.

Title: Process for the production of high lubricity low sulfur distillate fuels
Inventor: BERLOWITZ PAUL JOSEPH
IPC: C10L1/04
Filed: 1999-04-26
Abstract: A process for producing distillate fuels, such as diesel fuels and jet fuels, having both high lubricity and low sulfur levels. Such fuels are produced by fractionating a distillate feedstream (10) into a light fraction (12) which is relatively low in lubricity and which contains from about 50 to 100 wpm of sulfur and a heavy fraction (14) having a relatively high lubricity. The first fraction (12) is hydrotreated to remove substantially all of the sulfur (16) and is then blended with the second fraction (14) to produce a distillate fuel product (18) having relatively low sulfur levels and a relatively high lubricity.

Title: Crop material processor
Inventor: HRUSKA KEVIN
IPC: A01F29/02
Filed: 1999-09-17
Abstract: A baled crop material processor for disintegrating baled crop material comprising a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller that is mounted within the container and has a number of flails pivotally mounted about it. The flail roller rotates about its own longitudinal axis in either a clockwise or counter-clockwise direction. The discharge opening is at the bottom of one of the side walls to discharge the disintegrated crop material either to the left or to the right of the processor and in a bidirectional processor, the operator may alternate between sides. The manipulation means comprises manipulator rollers having paddles positioned at an angle to the length of the roller to rotate the crop material without substantially breaking the crop material apart. The paddles are channel shaped with outwardly curved ends to grasp the baled crop material for rotation and then to pull out of the crop material due to the curved end as the roller is rotated. Further, the angled paddles guide the crop material longitudinally toward the centre of the crop material processor away from the front and back walls. Moreover, the sidewalls of the container are shaped to have a protrusion projecting into the container in close proximity to the paddles, a spacing below the protrusion to prevent the accumulation of loose material, and outwardly sloped wall portions above the protrusion.

Title: Method and apparatus for optimized image processing
Inventor: CABANA GLENN EDWARD
IPC: H04N1/21
Filed: 2001-11-16
Abstract: An image processing system for digital printing for improving throughput and efficiency of the transfer of image data to imaging devices, such as lasers, while allowing for dynamic and continuous adjustment of image size and registration (i.e., alignment) on recording media. A buffer memory structure is configured to receive data from raw image files. Specific portions of data are copied from the raw image files into a buffer memory structure and, for compilation of the final image, into an image buffer. Image overlap is resolved by copying data into the image buffer according to a defined hierarchy. Using a phase locked loop, image size and registration are adjusted to optimize the appearance of the final image on the recording medium. The optimization is performed dynamically and continuously, thereby providing a uniform final image. Many aspects of the operation of the image processing system may be under the control of a digital computer.

Abstract: According to the invention the labels (22) are produced in a broad woven fabric (21) comprising ground warp yarn (4) and ground weft yarn (5) for a ground woven fabric (11), embroidery weft yarn (12) which forms a figure and code weft yarn (10) which forms a barcode, said yarn being distinguishable from the ground warp yarn only in a light outside the visible spectrum. In the broad woven fabric (21) several labels (22) are produced whose longitudinal sides (1) adjoin each other in the weft direction and remain unfolded and whose lateral sides (2) are adjacent to each other in the warp direction and can be folded. The embroidery weft yarn (12) and the code weft yarn (10) extend parallel to each other and at a distance from the longitudinal sides (1) so that the backs of the labels (22) are evenly covered and thus uniformly transparent.  The broad woven fabric (21) is cut along the lateral sides (2) into strips (25) each consisting of transverse labels (22) which are situated one behind the other in the warp direction. The labels (22) are then separated into individual labels by cuts along their longitudinal sides (1), which produces soft cutting edges (16) in the ground woven fabric (11) which do not irritate the skin.
