Filed: 1995-06-06
Abstract: The present invention relates to a method of stimulating the proliferation and appropriate cell maturation of a variety of different cells and tissues in three-dimensional cultures in vitro using TGF-.beta. in the culture medium. In accordance with the invention, stromal cells, including, but not limited to, chondrocytes, chondrocyte-progenitors, fibroblasts, fibroblast-like cells, umbilical cord cells or bone marrow cells from umbilical cord blood are inoculated and grown on a three-dimensional framework in the presence of TGF-.beta.. Stromal cells may also include other cells found in loose connective tissue such as endothelial cells, macrophages/monocytes, adipocytes, pericytes, reticular cells found in bone marrow stroma, etc. The stromal cells and connective tissue proteins naturally secreted by the stromal cells attach to and substantially envelope the framework composed of a biocompatible non-living material formed into a three-dimensional structure having interstitial spaces bridged by the stromal cells. The living stromal tissue so formed provides the support, growth factors, and regulatory factors necessary to sustain long-term active proliferation of cells in culture and/or cultures implanted in vivo. When grown in this three-dimensional system, the proliferating cells mature and segregate properly to form components of adult tissues analogous to counterparts in vivo.

Title: Image rendering system and method for generating stochastic threshold array(s) for use therewith
Inventor: KOLPATZIK BERND W
IPC: B41J2/52
Filed: 1996-03-22
Abstract: An image rendering system, for generating discrete tone image data representing a continuous-tone image for rendering by a rendering device, the image rendering system includes a stochastic threshold array generating arrangement and an image data processing section. The stochastic threshold array generating arrangement generates a plurality of stochastic threshold arrays from a random seed pattern that have been subsequently optimized to reduce image artifacts in the rendering of tones. Each pattern is optimized to reflect (i) a selected trade-off between grain and possible mottle in the rendered image, (ii) distortions introduced by the rendering device in rendering an image defined by the pattern and an observer in viewing the image, and (iii) boundary effects so that the patterns, when tiled together, have optimal visual characteristics proximate their respective edges. The image data processing section processes the continuous tone image data in relation to the stochastic threshold arrays generated by the stochastic threshold array generating arrangement. The image data processing section may be used to either randomly tile, or tile in an ordered way, the stochastic threshold arrays over the continuous-tone image data and generates the discrete tone image data in response to correspondingly positioned pixels of the continuous-tone image data and threshold values of the stochastic threshold arrays.

IPC: B23B31/107
Filed: 1996-05-03
Abstract: A quick release chuck device for releasably holding a jaw blade includes a body member having an internal longitudinal bore defined therein.  The longitudinal bore has a substantially rectangular cross-section shape for receipt of conventionally sized saw blades.  At least one radial bore is defined in the body member and is in communication with the longitudinal bore through one of its short sides.  An engaging device is disposed in the radial bore and is movable radially within the radially bore so that at least a portion of the engaging device extends into the longitudinal bore in a locking mode of the chuck device to hold a saw blade within the device through contact with a recess defined in the edge of the blade.  A spring-biased outer sleeve is disposed about at least a portion of the body member.  The outer sleeve is movable longitudinally between a released position and a locking position.  The outer sleeve member includes an engaging surface having a portion which contacts the engaging member and forces the engaging member radially inward to engage a saw blade inserted into the longitudinal bore in the locking position of the sleeve member.  The device is unlocked by an operator grasping the outer sleeve surface and moving the outer sleeve to its released position thereby allowing the engaging member to move radially outward to release the saw blade.

Title: Method for grinding of granular material and grinding equipment
Inventor: HINTIKKA VAINOE VILJO HEIKKI
IPC: B02C21/00

Title: Detection and quantification of one or more nucleotide sequence target analytes in a sample using spatially localized target analyte replication
Inventor: LEVINE ROBERT A
IPC: C12Q1/68
Filed: 1998-02-05
Abstract: A target analyte which may be found in a substance, such as a biological or environmental substance, is assayed by inoculating a media with a sample of the substance. The target analyte is a unique nucleotide sequence of the RNA or DNA of a suspect organism, or any nucleotide target, or a combination of nucleotide sequences thereof, which organism may be found in the substance. The media contains selected target analyte amplifiers which will result in the amplification of any target analytes which are present in the substance. The media may also contain one or more labeled analyte-specific materials (LASMs) which can migrate through the media. The nature of the media is such that it will support target analyte-copying but will not allow the target analyte to migrate extensively within the media.  After the substance to be assayed is added to the media and any target analytes are amplified, the LASMs will migrate by diffusion to resultant target analyte units or colonies in the media, thereby creating intensely labeled localized areas in the media which can be visually or mechanically detected. Each of the intensely labeled areas in the media will be surrounded by low intensity label halos. The number of high intensity labeled sites in the media will be proportional to the concentration of target analytes in the substance.
