Title: Dispersion shifted optical waveguide fiber
Inventor: BHAGAVATULA VENKATA ADISESHAIA
IPC: G02B6/028
Filed: 1995-06-27
Abstract: A single mode optical waveguide fiber designed for high data rate, or WDM systems or systems incorporating optical amplifiers.  The optical waveguide has a compound core having a central region and at least one annular region surrounding the central region.  A distinguishing feature of the waveguide core is that the minimum refractive index of the central core region is less than the minimum index of the adjacent annular region.     A relatively simple profile design has the characteristics of ease in manufacturing together with, flexibility in tailoring Dw to yield a preselected zero dispersion wavelength, dispersion magnitude over a target wavelength range, and dispersion slope.     The simplicity of profile gives reduced polarization mode dispersion.

Title: Human erythroid progenitor cell population
Inventor: BENDER JAMES G
IPC: A61K35/28
Filed: 1994-04-14
Abstract: The  invention  provides  a  method  of  preparing  from hematopoietic cells a population of cells enriched for erythroid progenitor cells (BFU-E) in which up to 100% of the colony-forming units are BFU-E.  The method entails separating hematopoietic progenitor cells on the basis of binding to a specific cell surface antigen such as CD34, and separation of  erythroid progenitor cells  based on binding to a lectin such as Ulex europaeus agglutinin. After separation of the erythroid progenitors, the lectin may be eluted off the cells by incubation with excess sugar, such as fucose, which competes for the cell-binding site on the lectin.  The invention also provides a method of  treatment  for  human  patients  having  an  erythroid disorder via administration of a cell population enriched for human erythroid progenitor cells.  Also provided are diagnostic methods based on the enriched cell population.

Title: Blow molding sealed container system
Inventor: HANSEN BERND
IPC: B29C49/48
Filed: 1995-10-23
Abstract: A blow molding method manufactures a sealed container and fills the container with a substance. The container body is connected to a head or top. A part of the head can be detached for opening of the container. A segment of an extruded tube is mounted in a blow mold having an axially movable mold base. The diameter of the extruded tube is slightly greater than the diameter of the head or top.      Following the closing of the tube end forming the bottom of the container, air is blown into the tube and simultaneously the mold base is moved toward the top jaws of the blow mold forming the head. After filling of the container and possibly mounting of an insert body into the top segment of the tube forming the container head or top, the mold base is moved still further in the direction of the top jaws, until the container is free of air. Then, the head is formed and is sealed securely with the outer surface of the insert body.

Patent CA-2170167-A1 (CA)
Title: Top
Inventor: TURECEK JOHN
IPC: B65D5/68
Filed: 1996-02-23
Abstract: A reusable container closure which telescopes over the open top or bottom of the container is formed by utilizing a one-piece paperboard blank which is cut, scored, and folded to present a central panel, and at least three side panels depending from the central panel. A first side panel has a corner flap. A second side panel has a notch. The first side panel and the second side panel meet to form a corner. The corner flap is folded about the corner to lie against the second side panel. The corner flap also has a friction stop folded to engage the notch, which extends through the notch. When the container closure is telescoped over the container, the container urges the friction stops towards the second side panel so that the container closure embraces the top of the container. When the container closure is later removed from the container, the friction stop is simply disengaged from the notch and the container closure may be flattened and returned for re-use.

Title: Methods for reprocessing dialyzers
Inventor: LEVIN NATHAN
IPC: A61M1/14
Filed: 1994-10-05
Abstract: A method for reprocessing dialyzer cartridges (13) used with kidney dialysis machines is provided.  The method involves filling the blood (19, 21) and dialysate (23, 25) compartments of the dialyzer (13) with an aqueous solution containing citric acid at a concentration of 1.0-5.0 wt. %, e.g., 1.5 wt. %, and then b; g the dialyzer (13) to an elevated temperature above 90 °C and below 100 °C, e.g., 95 °C, for a period of at least 15 hours, e.g., 20 hours. Although citric acid is non-toxic and the temperature used is below the boiling point of water, the process has been found to produce a fully sterilized dialyzer (13). After reprocessing, the aqueous citric acid solution is preferably left in the dialyzer (13) where it acts as a bacteriostatic agent during storage. Essentially no damage to the dialyzer (13) and, in particular, to its semipermeable membrane (11) results from either the reprocessing or storage procedures.

Abstract: Method and apparatus for the analytical determination of glucose concentration in a biological matrix, wherein in a detection step light from a light emitter is irradiated into the biological matrix as primary light via a boundary surface of the biological matrix  and  light  emerging  from the the biological matrix through a boundary surface is being detected by  a  light  detector  in  order  to  determine  a  measurable physical light property which is changed by interaction with the biological matrix and which correlates with the glucose concentration of said matrix.  The glucose concentration is ascertained in an evaluation step on the basis of said change of the physical light property determined in at least one detection step in comparison with a calibration. In order to achieve by such a method good analytical accuracy in reagent-free and non-invasive manner,  for instance to observe the change  of  the  concentration  of  the  analyzed  substance (monitoring)  over  an adequate  time  interval,  a  measurable parameter corresponding to the light transit-time within the biological matrix between a defined irradiation site and a defined  detection  site  and  correlating  with  the  glucose concentration is determined in the detection step.

Title: Personal communication device usable in two communication modes and personal telecommunication system including the device
Inventor: MARUYAMA KAZUHIKO
IPC: H04M11/00
Filed: 1996-08-22
Abstract: Both call switching communication and packet communication are achieved by one personal communication device.          Misreceiving in the personal communication device usable in two communication modes is prevented. The personal communication device has a call switching modem and a packet switching modem. The former is used for AMPS network, and the latter for CDPD network. A telecommunication system comprises a transmission/receiving terminal and a telecommunication network. The packet switching modem of the terminal carries out awaiting of the receiving and initial transmission. In this system, the transmission terminal first sends a CDPD packet to the receiving terminal. The receiving terminal is informed of a request for call switching communication. The receiving terminal sends back a response to the request as a CDPD packet, and then a call in the AMPS network is made.          Although the personal communication device is usable in the two modes, misreceiving does not occur because awaiting is in a fixed mode.
