Inventor: BRIMHALL GREG L
IPC: A61M39/06
Filed: 1997-04-22
Abstract: The assembly of this invention comprises an elastic plug that is retained in a medical device, such as a catheter. A needle having a distal portion and a proximal portion resides in the elastic plug. The proximal portion has a different cross-section than the distal portion. In one embodiment, the cross-section of the proximal portion is smaller than the distal portion. Upon removal of the needle from the catheter and the elastic plug, the space in the elastic plug that had been occupied by the proximal portion of the needle is closed to effectively achieve the sealing function of the plug. The needle may include one or more notches in fluid communication with the needle lumen. One notch is preferably located at the juncture between the proximal portion and the distal portion of the needle to facilitate the blood flow between the needle and the catheter for better visualization of blood flashback by the clinician.

Title: Method and apparatus for performing lzw data compression utilizing an associative memory
Inventor: COOPER ALBERT B
IPC: G06T9/00
Filed: 1995-12-18
Abstract: An associative memory (11) is utilized to perform LZW data compression. The respective locations of the memory contain a prefix code field (12) and a character field (13). A register (20) containing a code field (21) and a character field (22) is associatively compared to the locations of the memory to determine if a match exists therewith. If a match is found, the address (14) of the match is inserted in the code field of the register and the next input character is inserted in the character field thereof. This process is continued until no match occurs. The code existing in the code field of the register is transmitted (34) as the compressed code of the string and the contents of register is written into the next empty location of the memory. A  next cycle is initiated by nulling (40) the code field of the register and repeating the described steps.

Title: Digital information recording media and method of using same
Inventor: MACDONALD JOHN GAVIN
IPC: G09F3/02
Filed: 1996-06-03
Abstract: A digital information recording media which includes a recording layer comprising a light-stable colored composition which composition is mutable or decolorizable upon exposure to a specific wavelength of ultraviolet radiation.  The light-stable colored composition includes a colorant and an ultraviolet radiation transorber. The colorant, in the presence of the radiation transorber, is adapted, upon exposure of the transorber to specific, narrow bandwidth ultraviolet radiation, to be mutable. The radiation transorber also imparts light-stability to the colorant so that the colorant does not fade when exposed to sunlight or artificial light. The ultraviolet radiation transorber is adapted to absorb radiation and interact with the colorant to effect the irreversible mutation of the colorant. Especially useful radiation is incoherent, pulsed ultraviolet radiation produced by a dielectric barrier discharge excimer lamp or coherent, pulse radiation produced by an excimer laser. In another embodiment, the colored composition which comprises a colorant and an ultraviolet radiation transorber may also contain a molecular includant having a chemical structure which defines at least one cavity. Each of the colorant and radiation transorber is associated with the molecular includant. In some embodiments, the colorant is at least partially included within a cavity of the molecular includant and the ultraviolet radiation transorber is associated with the molecular includant outside of the cavity.  In other embodiments, the radiation transorber is covalently coupled to the molecular includant.

There is also provided a method for making the polymeric compound that will be formed into a product, such as an applicator or applicator barrel in which all of the above ingredients, except for the thermoplastic resin, are combined and formed into soft pellets. The soft resin pellets are then dry blended with pellets of the thermoplastic resin. The mixture of the thermoplastic resin pellets and the soft resin pellets are then melted and injection molded into the desired shape. There is thus provided a method of making a soft, polymeric tampon applicator or tampon applicator barrel.
Patent CA-2222562-A1 (CA)
Title: Method for screening for receptor agonists and antagonists
Inventor: WEN XIAOHONG DAWN
IPC: C12Q1/68
Filed: 1996-06-06
Abstract: This invention relates to a method for identifying a receptor agonist or antagonist by providing a nucleic acid encoding a receptor having a first TAF region able to activate transcription from a promotor, and a second TAF region mutated to have the functional context of the second TAF region, but not able on its own to activate transcription of the promoter. The nucleic acid is provided within a cell unable to exhibit transcription from the promoter in the presence of the second TAF region alone, but able to exhibit transcription from the promoter in the presence of the first TAF region. The cell further includes a reporter construct containing the promoter operatively linked to a reporter gene. The reporter gene is transcribed when the promoter is activated in the presence of the first TAF region. The method further includes contacting the cell with a potential agonist or antagonist, under conditions in which contact of the cell with a known agonist or antagonist of the receptor increases or decreases transcription from the promoter and the level of the product of the reporter construct. Finally, the method involves measuring the level of increase of the product of the reporter construct as an indication of the agonist activity of the potential agonist. The method is applicable to intracellular receptors including ER, AR, PR and GR.
