Patent CA-2242680-A1 (CA)
Title: Pure, viable and human epithelial cell preparations obtained from digestive tissue and method of preparation thereof
Inventor: BEAULIEU JEAN-FRANCOIS
IPC: C12N5/071
Filed: 1998-07-09
Abstract: The basement membrane (BM) underlying the epithelium of the intestine is generally believed to be of both epithelial and mesenchymal origin but the exact contribution of each tissue has not been directly examined in the human. In this study, we have used a newly described procedure to dissociate the human intestine into pure epithelial and corresponding mesenchymal fractions. Northern blot and RT-PCR analyses of the fractions for the presence of transcripts encoding extracellular matrix molecules revealed that the epithelium produces the formal BM molecules such as the .alpha.1, .alpha.2, and .beta.1 chains of laminin-1 and laminin-2 and the .alpha.5(IV) and .alpha.6(IV) chains of collagen as well as fibronectin, a BM- associated molecule. Interestingly, the .alpha.1 (IV) chain of collagen, which associates with the .alpha.2(IV) chain to form the main BM collagen network, as well as tenascin-C and decorin, two BM associated molecules, were found to be exclusively of mesenchymal origin. Taken together, these data support the concept that in the human, as in experimental animals, the intestinal BM is comprised of components produced from both the epithelium and the mesenchyme.

Title: High-volume sand trap and method
Inventor: RONNESETH HALVOR S
IPC: E21B27/00
Filed: 1998-11-23
Abstract: A sand-capturing tool is disclosed, as well as a method, The tool relies on an eductor. The eductor is supplied by pumped fluid from the surface through a coiled tubing support for tho tool. The eductor induces flow into a central tube in the tool which brings in with it the sand to be captured.  Ultimately, the cross-sectional area of the induced fluid flow is increased to reduce its velocity and to further induce the sand which has been brought through the narrow inner tube to drop out into an annular area around the inner tube. The clean fluid exits through a screen and goes around the eductor and uphole to the surface. In an alternative embodiment, the assembly can be supported on an electric line employing a downhole pump which provides the motive fluid force for the eductor jet, In this embodiment, the remaining operation is the same.

Patent CA-2259818-A1 (CA)
Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N19/89
Filed: 1994-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.

Title: System interconnection device and method of designing same
Inventor: MATSUBARA YOSHIO
IPC: H02H9/02
Filed: 1999-04-07
Abstract: A system interconnection device connected between two systems, such as a commercial bus line carrying power from a commercial power line and a private bus line carrying power from a private power generator, is able to connect and disconnect the two systems, and, in the event of a fault, has a current-limiting effect, thus preventing instantaneous voltage drop of the respective bus lines. In the system interconnection device, unit parallel circuits made up of diodes and DC reactors are serially connected so that the diodes thereof have opposite directions. With this structure, in realizing operations equivalent to those of a conventional system interconnection device having a DC reactor between DC terminals of a single-phase rectifying bridge circuit, the number of diodes, which are rectifying elements, can be halved. This not only enables reduction of the total cost of elements, but also, particularly in high-voltage and extra-high-voltage systems, enables great reduction of the cost and space devoted to insulation.

Title: Aal2 packet exchange device
Inventor: DEMPO HIROSHI
IPC: H04L47/43
Filed: 1999-05-31
Abstract: An AAL2 packet exchange device is placed in front of an ATM switch for executing CPS packet re-multiplexing into ATM cells. The AAL2 packet exchange device extracts CPS-PDUs (Common Part Sublayer- Protocol Data Units) from ATM cells which are supplied from input ATM lines, extracts CPS packets from the CPS-PDUs, alters CIDs (Channel IDentifiers) of the CPS packets if necessary so that CID collision will not occur between CPS packets supplied from different sources to be outputted to the same output ATM connection, multiplexes the CPS packets to be outputted to the same output ATM connection in ATM cells of the same output ATM connection. The CID alteration is executed by referring to a path setting table which stores each correspondence between a first internal address for discriminating between input ATM connections, an input CID, a second internal address for discriminating between output ATM connections, and an output CID.    By the CID alteration, CPS packets which have been contained in ATM cells from different sources can be multiplexed onto the same VP/VC.    Therefore, multiplexing efficiency on each ATM connection can be improved, and thereby increase in the number of ATM cells can be avoided and the load on ATM switches can be lightened.

Patent CA-2279997-A1 (CA)
Inventor: COWELL MARK
IPC: B23K3/03
Filed: 1998-02-10
Abstract: A technique for producing soldering iron tips entails cutting clad wire into a plurality of segments, each segment comprising a core of material (such as copper) and an outer protective layer (such as stainless steel, Ni, Cr, or alloy thereof). Each clad wire segment is then shaped into a soldering iron tip by a cold or hot heading process, or other metal forming process. In the finished tip, the protective outer layer is disposed behind the working area of the tip, and serves to reduce the corrosion of the tip, and to improve the electrical conductivity between the tip and the soldering iron handle. A heater element can be formed at one end of the soldering iron tip from the same clad wire segment used to produce the tip itself, thereby ensuring good thermal transfer properties between the heater element and the tip. The invention also pertains to a technique for forming a protective outer layer on the working area of the tip. The technique comprises stamping caps from a thin strip or sheet of protective material, such as iron. More specifically, the caps are stamped out of the sheet using a die having a shape which resembles the shape of the working area of the soldering tip. The caps formed in this manner are then inserted over the ends of the tips, and attached thereto by applying brazing material to the formed cap or to the strip of material prior to forming the cap.
