Patent CA-2212283-A1 (CA)
Inventor: SAMS BERNARD
IPC: A61J1/10
Filed: 1997-08-05
Abstract: A connector assembly is provided for efficient flow of liquid into and/or out of a vial, such as a vial containing a lyophilized drug. The connector assembly includes a spike and a stopper sleeve, both slidably mounted in the open top of the vial. The connector assembly includes a stopper affixed to the stopper sleeve and sealingly engaged in the open top of the vial. The stopper is slidably moveable in response to axial movement of the stopper sleeve. Movement of the stopper sleeve relative to the vial will move the stopper into or out of sealing engagement with the vial. The connector assembly further includes a spring for generating a small amount of axial movement of the spike, stopper sleeve and stopper after the stopper has been moved into the opened position in the vial. Movement of the spike, stopper sleeve and stopper generated by the spring will cause a sufficient change in pressure to overcome surface tension and initiate an efficient flow of fluid into or out of the vial.

Patent CA-2216011-A1 (CA)
Title: "adpcm transcoder"
Inventor: PINIER FRANCOIS
IPC: H03M7/38
Filed: 1997-10-06
Abstract: Known ADPCM transcoders use processors for coding and decoding, which are time and power consuming. Such a known ADPCM transcoder comprising one processor for coding and decoding can handle four channels, while according to DECT twelve channels need to be available, which requires three known ADPCM transcoders. By delaying signals in an ADPCM transcoder, it is no longer necessary to use processors, but, instead of said processors, logic elements can be used, which is very advantageous, because of such an ADPCM transcoder being able to handle sixteen channels.

IPC: H04N1/405
Filed: 1996-02-16
Abstract: A spread spectrum digital screening mask and a method and system for digital screening a continuous tone image with the spread spectrum digital screening mask. The mask is characterized in the frequency domain by a function in magnitude independent of angle within a band of frequencies between a minimum frequency and a maximum frequency. The mask may be further characterized by its thresholded binary planes at each of a plurality of predetermined threshold values. The binary planes are characterized in frequency domain by magnitude primarily distributed within the band of frequencies. For each binary plane, the number of pixels having one of the binary values divided by the total number of pixels in the binary plane equals a fraction determined by the predetermined threshold value of the binary plane divided by the maximum threshold value.

Abstract: A method, apparatus and computer program product for caching data received from a first application and to be provided to a second application in response to a request from the second application. The method, apparatus and computer program products include storing a data stream to be received from the first application and to be provided to the second application in a cache to create a client cache entry corresponding to the request from the second application. The time of creation of a client cache entry is also stored to create a client cache entry time record. Requests from the second application are interrogated to determine if a client cache entry exists corresponding to the request. The client cache entry time record for the client cache entry corresponding to the request from the second application is evaluated to determine if the client cache entry corresponding to the request from the second application was created within a predetermined client coherency time interval prior to the second application requesting the information. The client cache entry is suppplied to the second application in response to the request if a client cache entry for the request from the second application was created within a predetermined client coherency time interval prior to the second application requesting the information.

Filed: 1998-02-25
Abstract: An apparatus and method for gluing disc halves together during manufacturing of data storage optical discs including a main support, on which a first disc half is arranged in an elastic-deformation condition.  A second disc half, optionally resiliently deformed to a conical configuration, is arranged under an auxiliary support axially opposed to the main support.          An adhesive dispenser delivers an adhesive for distributing the adhesive along the outer circumferential edge of the first disc half, following a rotation imparted to the dispenser of the disc half about the respective axis.  The dispensed adhesive spreads by gravity along the glued surface of the disc half and is thereby evenly spread thereon.  The second disc half is then lowered onto the first disc half to achieve mutual pairing of the first and second disc halves.

Title: Csa1 gene coding for a candida albicans surface antigen, diagnostic and therapeutic uses thereof
Inventor: BOURBONNAIS YVES
IPC: C12Q1/68
Filed: 1998-07-10
Abstract: We have recently described the production of monoclonal antibodies (MAbs) directed against surface antigens of the Candida albicans yeast and mycelial forms, respectively. The mycelial surface antigen recognized by MAb 4E1 was shown to be present predominantly in the terminal third of the hyphal structures. We have now cloned the corresponding gene (CSA1) by MAb 4E1-coated magnetic beads sorting of S. cerevisiae transformants expressing a Candida albicans genomic library. The strategy is both highly selective and sensitive and provides an additional genetic tool to facilitate cloning of Candida genes encoding surface proteins. CSA1 is an intronless single copy gene in Candida and whereas RNA transcripts can be detected in exponentially growing yeast cells, gene expression is strongly increased upon induction of the mycelial growth phase. The deduced amino acid sequence of Csa1p (1203-residues) shares many features with other cell wall proteins including the presence of repetitive motifs and domains. Most strikingly, a Cys-rich hydrophobic domain of 102 amino acids that is repeated five times in the protein shows significant sequence similarity with a major T-cell immunoreactive antigen (Ag2) from another opportunistic fungal human pathogen; Coccidioides immitis. This suggests that Csa1-like proteins may confer unique properties to the cell wall of fungal pathogens.

Abstract: Phosphor compositions are prepared by treating metal oxides or mixed-metal oxides with refractory metals to form cathodoluminescent phosphors stimulatable by electrons of very low energy. The phosphors comprise 90 % to 100 % of a mixed metal oxide MxTyOz (where M is a metal selected from Zn, Sn, In, Cu, and combinations thereof; T is a refractory metal selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and combinations thereof; and O is Oxygen, x, y, and z being chosen such that z is at most stoichiometric for MxTyOz) and 0 %  to 10 % of a dopant comprising a substance selected from a rare earth element of the lanthanide series, Mn, Cr, and combinations thereof, or stoichiometrically excess Zn, Cu, Sn, or In. A blue-light-emitting phosphor based on ZnO treated with Ta2O5 or Ta to form Ta2Zn3O8 is characterized by CIE  1931 chromaticity values x and y, where x is between about 0.14 and 0.20 and y is between about 0.05 and 0.15. In preferred embodiments, a process is specially adapted for forming the phosphor in an electrically-conductive thin-film or surface-layer form in situ during fabrication of displays. A preferred in situ process has an integrated etch stop, which precisely defines the depth of an opening in a field-emission display structure utilizing the low-energy-electron excited phosphor. A field-emission display comprises cells, each having a field-emission cathode and an anode comprising at least one cathodoluminescent phosphor. Arrangements of various color phosphors may be made by selective deposition of suitable dopants. The display cell structures may also have gate elements for controlling electron current flowing to the anode and its phosphor when suitable voltages are applied.
