Patent CA-2279038-A1 (CA)
Title: K-kaps
Inventor: LASAGNA PHIL
IPC: A42B1/24
Filed: 1999-08-06
Abstract: The world of baseball at either the Little League or Major League level has always included enthusiastic fans. Good-natured cheering shows support and allows the fans to get behind the players. In many Little-League organizations, it is common practice to put up a "K" every time the pitcher gets a strike-out. This is usually done by having one parent putting up a poster or piece of paper on the fence. This invention has been designed so that individual fans can also get involved. Similar to the custom of "rally caps" (putting up the peak of your baseball cap, putting you baseball cap on inside out) to motivate a team, "K-KAPS" spur the team on. This invention is a new version of a baseball cap. It has been designed for sports fans to keep track of the number of strike-outs for their favorite pitcher or team. Sewn into the front of the cap will be 21 flaps that when opened will each reveal a "K" (baseball symbol for a strike-out). When the flaps are closed the cap will look like a normal baseball cap. Every time a strike-out occurs, a single flap is opened and locked into place, revealing a "K"

Title: Knockout animals
Inventor: KOHNO KENJI
IPC: A01K67/027
Filed: 1998-01-30
Abstract: Transgenic mice constructed by binding the "hHB-EGF/DTR" gene to the downstream of an albumin enhancer/promoter expressed specifically in hepatic parenchymal cells and then transferring the same into mice. After confirming that the "hHB-EGF/DTR" gene has been expressed specifically in hepatic cells, diphtheria toxin is administered to the transgenic mice to examine whether the disruption of the hepatic parenchymal cells proceeds or not. Thus, the hepatic cells of the transgenic mice can be successfully disrupted selectively depending on the administration period of the diphtheria toxin.

Title: Process for chiral enrichment of optically active carboxylic acids, or salts or esters thereof
Inventor: PHAN HAO V
IPC: C07B57/00
Filed: 1998-04-03
Abstract: A highly efficient method for enriching the chiral purity of a partially enriched mixture of enantiomers of an optically active compound, a major portion of the partially enriched mixture of enantiomers comprising a first enantiomer of the optically active compound, a minor portion of the partially enriched mixture of enantiomers comprising a second enantiomer of the ptically active compound. The method comprises mixing an acid in whatever form it may exist in solution with an aqueous solution of the partially enriched mixture of enantiomers, in whatever form the partially enriched mixture of enantiomers may exist in solution, to form a reaction mass comprising a further enriched mixture of enantiomers of the optically active compound, the further enriched mixture of enantiomers having a higher percentage of the first enantiomer than the partially enriched mixture. The optically active compound has the formula:  R1R2R3CCOOZ, where R1, R2 and R3 are different from each other and are selected from the group consisting of a hydrogen atom, hydrocarbyl groups, hydrocarbyloxy groups, hydrocarbylthio groups, hydrocarbylcarbonyl groups, halohydrocarbyl groups, hydrocarbyloxyhydrocarbyl groups, heteroaromatic groups, and halogen atoms, with the proviso that none or only one of R1, R2 and R3 can be a halogen atom, and where Z is an alkali metal cation, a cation of a nitrogenous base or a combination of the foregoing.
Patent CA-2286597-A1 (CA)
Title: Method of avoiding packet loss at a handover in a packet-based telecommunications network and handover method
Inventor: RAUHALA KRISTIAN
IPC: H04L12/56
Filed: 1998-04-09
Abstract: The invention relates to connection-oriented packet-based communications network, such as ATM (Asynchronous Transfer Mode), in which the terminal (MS) and the network access point of the terminal may move in the network. When the access point of the terminal (MS) changes during an active connection, the routing of the connection must also be changed or extended from an old access point (BTS1) to a new one (BTS2). The old access point (BTS1) may comprise buffered cells, which should be transferred to the new access point without packet loss. A necessary connection (13) from the old access point to the new one is established dynamically, when it is required. Instead of being controlled by the old access point, the connection establishment is controlled by a third network element (10), which is responsible for controlling the change of access point anyway. The third network element (10) generates the required signalling and in a way "tunnels" this signalling to the old access point (BTS1), which transmits the signalling forward without interpreting it.  So the old access point can be arranged to send signalling messages and to establish a connection without requiring any additional intelligence at the access point. Upon the connection being established, the old access point sends the buffered unsent packets to the new access point (BTS2).

Abstract: The present invention provides financial transaction processing systems and methods. One preferred embodiment of a method according to one aspect of the present invention includes generating an optically scanned image (34, 208) of at least a portion of document containing visual data, in a particular format, representing information related to the financial transaction. Recognition characteristics (32, 204) are generated from the scanned image and are compared (40, 220) to respective sets of reference recognition characteristics generated from respective other transaction documents having different respective formats to determine therefrom whether the particular format of the visual data matches one of the respective formats of the other documents. When such a match is found to exist, location is determined (40, 218) of a field in the scanned image to which optical character recognition may be applied to generate therefrom the information, based upon the respective format found to match the particular format of the visual data. Optical character recognition is then utilized to generate said visual data (60, 232) from said location.
