Patent CA-2224108-A1 (CA)
Inventor: GAVORA JAN S
IPC: C12N15/85
Filed: 1998-02-24
Abstract: A method is described to transfer a gene encoding a valuable compound, such as apharmaceutical, into the secretory cells of the mammary gland to produce a new compound into the milk or to alter the composition of the milk. In this method the packaging cell line producing the viral-derived particles is infused into the mammary gland. The packaging cells will attach and survive for a period of time within the mammary gland. While the cells are viable, they will supply a continuous source of viral-derived particles to trans-infect the maximum number of mammary epithelial cells. After a period of time in the mammary gland, both the particles and the packaging cells will be destroyed by natural mechanisms while the trans-infected mammary epithelial cells continue to express gene(s) encoding the valuable compound or gene(s) to alter the composition of the milk. One or more genes can be trans-infected including DNA sequences that contribute to the efficient production of an active compound or to its stability. The packaging cells and the viral-derived particles used in this method can be those which trans-infect dividing or non-dividing cells and can be used either singly or together. This method can be used alone or in combination with other novel methods designed to ensure that the viral-derived particles are correctly positioned to trans-infect the mammary epithelial cells. Increasing the trans-infection of the mammary epithelial cells with the viral particles will result in a higher concentration of the valuable compound in the milk.

Patent CA-2230197-A1 (CA)
Title: Strand orientation sensing
Inventor: BARNES DEREK
IPC: G06T5/00
Filed: 1996-08-20
Abstract: The orientation of strands relative to a selected axis is determined by analyzing a digitized grey scale image to select edge pixels therefrom that may define the edges of strands segmenting the image into a plurality of subimages and processing one of the subimages by defining pixel lines merging the pixel lines to form lines segments and culling selected one of the lines in the subimage. The subimage is then combined to co-terminus other of the subimages to form a combined subimage which is processed in the same manner by merging pixel lines to form lines and culling selected line in the combined subimage. This process is repeated by combining further subimages and processing until substantially all of the image has been processed to provide the plurality of strand lines defining strand edges and then determining the orientation of the strand lines relative to the axis.

Abstract: The labyrinth path in the corrugating nip of a single facer is substantially reduced by utilizing a small diameter corrugating roll captured between a larger diameter conventional corrugating roll and a backing roll arrangement.  The smaller diameter corrugating roll is captured to prevent bending thereof under corrugating loads.  The corrugator may be operated at high speeds without the adverse increase in labyrinth path and web tension characteristic of a pair of large diameter corrugating rolls.

Title: Coated endovascular stent
Inventor: CHAN RANDY
IPC: H01L23/482
Filed: 1998-04-24
Abstract: An implantable stent is coated with a material that attracts heparin and with which heparin forms a bond.   The stent is exposed to a heparin containing solution just prior to implantation  or  is  first  implanted  and  then  exposed  to heparinized blood.  As heparin becomes detached from the stent, the implantation site is exposed to heparin to restore an effective level and thereby prevent thrombosis.

IPC: B01D21/26
Filed: 1995-11-14
Abstract: A vortex system for separating particles of varied size and density from a liquid stream. A particle bearing liquid is introduced tangentially into one end of an elongated cylindrical chamber through an inlet (13) to form a rotating liquid vortex therein. An impeller (18) at one end of the chamber reinforces the vortex flow. A series of tangentially oriented jets (21) introducing a gas further increases the vortex rotational flow. The vortex produces a heavy particle rich outer region, a gas and light particle rich axial region and a cleaned liquid annular region therebetween. The cleaned liquid flows out of the chamber through an outlet (30) at the chamber end opposite the end at which the particle bearing liquid is introduced. The heavy particles in the outer region are removed through outlet (24) and the gas and light particles in the axial region are removed through outlet (26).

Title: Polyphase static var compensator arrangement
Inventor: GRIFFITHS PETER THOMAS
IPC: H02J3/18
Filed: 1996-11-27
Abstract: A polyphase thyristor-switched-capacitor static var compensator (SVC) arrangement employs a transformer means (21) connected to the capacitors of the SVC (33, 43, 53) and configured such that when the capacitors are switched out of circuit in sequence, a residual charge on the capacitors is reduced by the transfer of energy between the capacitor and an energy-dissipation means by way of the transformer means.      The primaries of the transformer (31, 51, 41) means are connected across respective capacitors, while the secondaries (32, 52, 42) are connected in series in a delta configuration.      Damping resistors (34, 54, 44) may be connected in series with the primaries to help dissipate the capacitor energy. The transformer means may be saturable and may be constituted by individual transformers or one polyphase transformer. An alternative configuration applicable to a three-phase system employs a single-phase transformer having its primary connected across two series-connected capacitors of two of the phases, while its secondary is connected across the remaining capacitor.

Inventor: TORSTENSSON ANDERS
IPC: H04B7/005
Filed: 1997-01-17
Abstract: Techniques for providing a hearing aid compatible mode of transmission for a mobile station in a radio communication system are described. By adjusting a transmission envelope of a mobile station which transmits information in a burst fashion, harmonics which would normally be introduced into a hearing aid placed in close proximity with the mobile station are avoided. The modified transmission envelope provides a more gradual up and down-ramping of power to the transmitter to avoid introducing harmonics in the audio frequencies. This service can be provided at a system level in a manner which will avoid unnecessarily reducing system capacity by, for example, authenticating a user's identity, his or her subscription to this mode of operation, the mobile station's ability to modify the transmission envelope according to the present invention, and the user's desire to actually implement the hearing aid compatible mode of operation.

Title: Apparatus for synthesis of multiple organic compounds with pinch valve block
Inventor: WELLER HAROLD NORRIS III
IPC: B01L3/00
Filed: 1998-08-28
Abstract: The simultaneous synthesis of diverse organic compounds is performed in stackable modules which are moveable among nesting sites located on work station platforms.  The reactor module includes a block adapted to receive an array of tube-like reactor vessels.    The  vessels  are  sized  to  optionally  accept  porus polyethelyene mircocannisters with radio frequency transmitter tags.  Each vessel has a bottom port connected to an outlet tube.          A valve block located below the reactor vessels simultaneously controls discharge through the outlet tubes.   The valve block includes plates with aligned, relatively moveable sets of rib surfaces which act through Teflon encapsulated silicone O-ring cord sections to simultaneously close rows of outlet tubes.  By first utilizing reactor vessels in one set of 48 positions, out of the possible 52 reactor vessel positions in the reactor block, and then utilizing reactor vessels in the other set of 48 positions and shifting the relative position of the collection plate, a single reactor can be employed to discharge into all of the wells of a standard 96 well microtiter collection plate.  The apparatus can be used to perform the entire synthesis or only the final cleavage step of a radio frequency tagged synthesis.
