Title: Vial connector assembly for a medicament container
Inventor: SAMS BERNARD
IPC: A61J1/10
Filed: 1997-07-28
Abstract: A connector assembly provided for efficient flow of liquid into and/or out of a vial, such as a vial containing a lyophilized drug The connector assembly features a collar mountable to the rim of the vial in a locked position and thereafter removable by an end-user when disposal of the device is desired. A protective cap mountable over the collar includes a annulus-type ring at its proximal end which mounts over locking structure associated with the collar. The ring is secured to the protective cap via one or more user-severable connections. As the cap is urged proximally, the ring places the collar in the locked position with the vial rim, exerting an inwardly-directed force onto the locking structure the collar to the vial rim. The cap can be separated from the ring at its user-severable connections, and the device used in its ordinary matter. When disposal is desired, the ring may be urged proximally out of engagement with the locking structure of the collar The collar may thereafter be removed from the vial to facilitate separate disposal of those components.

Title: Improvements in or relating to continuously-variable-ratio transmissions
Inventor: FELLOWS THOMAS GEORGE
IPC: F16H15/38
Filed: 1996-03-15
Abstract: A variator for a continously-variable-ratio transmission (CVT) of the half-toroidal traction roller type in which a ratio change results when a roller (6) exercices a first freedom of movement by rotating about a first or precession axis (10). In addition, the roller mounting has a further freedom of movement about a second or tilt axis (16). The precession axis (10) is inclined at an angle ("the castor angle") to a plane lying normal to the axis of the races, and each equilibrium value of the ratio angle correlates with a unique angular orientation of the roller (6) about the tilt axis (16).

Patent CA-2217589-A1 (CA)
Title: Digital transmission framing system
Inventor: PAWLOWSKI CHRISTOPHER A
IPC: H04J3/06
Filed: 1997-10-06
Abstract: A digital transmission framing system utilizing an address array containing pointers to a framing pattern reference register.  The address array contains an entry for each set of possible framing bits.  Pointer values reference the last bit of a consecutive-bit sub-pattern of the reference register that the previously received bits in this frame bit position have matched.  As data bits are received, the associated pointer value is incremented by one to point to the next bit of the reference register, and the received data bit is compared to the newly referenced reference register bit. If the received data bit matches the newly referenced reference register bit, the associated pointer is updated with the incremented value and the corresponding frame bit position of the received data bit remains a candidate for the actual framing bit position.  This matching operation continues until only one eligible framing bit position is identified in the input data frame.  Bit 0 of the framing bit pattern in the transmission stream is then identified and a synchronization signal is generated.

Title: 2-deoxystreptamine as a molecular scaffold for preparing functionally and spatially diverse molecules and pharmaceutical compositions thereof
Inventor: GUSTAFSON GARY R
IPC: C07C217/58
Filed: 1996-09-06
Abstract: 2-Deoxystreptamine is an aminocyclitol whose structural stability and abundant functionality make it an attractive scaffold for the combinatorial generation of small molecules. The ability to selectively functonalize the various positions of 2-deoxystreptamine with an almost infinite number of different groups ensures that the libraries so generated will be both spatially and functionally diverse. These compounds can then be screened for biological activity to afford lead compounds for pharmaceutical programs. Additionally, biological ligand mimics based on 2-deoxystreptamine can be readily appended, either directly or through a tether, to solid surfaces or incorporated covalently into gels to afford novel materials useful in separation science.

Title: A logical link connection server
Inventor: BALDWIN JOHN HENRY
IPC: H04W88/00
Filed: 1998-03-17
Abstract: A digital cellular/personal communications service (PCS) application incorporates a logical link connection (LLC) server. In this approach, there are two ATM connections in the path of an AAL-2 connection: one between a base station and the LLC Server and the other between the LLC Server and a vocoder group. All LLCs from, or to, a given base station use a common ATM connection irrespective of the vocoder used at the other end. Similarly, all LLCs from, or to, a given vocoder group use a common ATM connection irrespective of the destination base station at the other end. At the LLC Server, LLC packets from many base stations destined for the same vocoder group are extracted and bundled into the ATM connection between the LLC Server and the destination vocoder group. Similar treatment is given to the packets originating at vocoders and destined for base stations. Thus, each ATM connection between a particular base station and the LLC server and each ATM connection between the LLC Server and a particular vocoder group are used to maximum capacity notwithstanding each ATM connection conveys LLCs to different LLC endpoints.

Patent CA-2236015-A1 (CA)
Title: System for customized electronic identification of desirable objects
Inventor: SALZBERG STEVEN L
IPC: G06F17/00
Filed: 1996-10-29
Abstract: This invention relates to customized electronic identification of desirable objects, such as news articles, in an electronic media environment, and in particular to a system that automatically constructs both a "target profile"  for each target object in the electronic media based, for example, on the frequency with which each word appears in an article relative to its overall frequency of use in all articles, as well as a "target profile interest summary" for each user, which target profile interest summary describes the user's interest level in various types of target objects. The system then evaluates the target profiles against the users' target profile interest summaries to generate a user-customized rank ordered listing of target objects most likely to be of interest to each user so that the user can select from among these potentially relevant target objects, which were automatically selected by this system from the plethora of target objects that are profiled on the electronic media. Users' target profile interest summaries can be used to efficiently organize the distribution of information in a large scale system consisting of many users interconnected by means of a communication network. Additionally, a cryptographically-based pseudonym proxy server is provided to ensure the privacy of a user's target profile interest summary, by giving the user control over the ability of third parties to access this summary and to identify or contact the user.

Title: Creation of bragg reflective gratings in waveguides
Inventor: ROURKE HOWARD NEIL
IPC: G02B6/124
Filed: 1998-04-27
Abstract: A method of avoiding unwanted phase discontinuities between adjacent sections of a long Bragg grating written section-by-section in an optical fibre uses masks with alignment parts additional to their writing parts.      Each alignment part is a replica of a portion of the writing part of the adjacent mask. Light of the same wavelength as used for writing grating sections excites stronger luminescence in regions of waveguide where there has been no irradiation induced raising of the refractive index than in regions where such index raising has occurred. Therefore, for such light directed through the alignment part of the mask and into the already-written previous section of the grating, the intensity of luminescent light propagating to an end of the waveguide varies according to how well or how badly the bright fringes produced by the mask register with the corresponding irradiated portions of the written Bragg grating. Fine adjustment of mask position is made to obtain the intensity corresponding to the desired level of registry before writing with this mask is commenced.
