Title: A method and apparatus for distributing currency
Inventor: JOHNSON DAVID L
IPC: G06F19/00
Filed: 1994-10-14
Abstract: A magnetic stripe card with an encoded card number including a bank identification number and an account number is issued to a customer with a value selectable by the customer. The central card processor establishes a zero balance database including the card numbers, but with blank fields for the customer data and the value of the account.      When a customer purchases a card, the sales agent transmits to the central database computer which fills in the blanks in the database, activating the account, and transmits an acknowledgment. The card can be immediately used in ATM or other remote terminals to acquire cash or purchase goods and services. The customer inputs a PIN number which is provided with the card, or an alternative PIN number selected by the customer.
Patent CA-2258967-A1 (CA)
Inventor: JANSEN JOSEF
IPC: A61F2/24
Filed: 1997-06-18
Abstract: A mitral valve prosthesis consists of a support housing (stent) with a large base ring that bears two stays which substantially extend in the ring axis direction and are connected by curved walls for securing two flexible cusps. The free ends of the stays form an inner support for the cusps. In order to avoid a possible mutual interference between the heart and valve functions, the base ring (12) has in the top view a closed, non-round shape with a common longitudinal axis (15) but two transverse half-axis (16, 17) of different sizes. The stays (18, 19) lie on the longitudinal axis (15) and form the transition between the two halves of the valve. The less curved wall (13) carries a (mural) cusp (11) having a smaller surface and a higher angle of inclination relative to the base ring base surface than the more curved wall (14).

Title: Polymer electrolyte membrane fuel cell with fluid distribution layer having integral sealing capability
Inventor: STUMPER JUERGEN
IPC: H01M8/24
Filed: 1998-04-30
Abstract: An electrochemical fuel cell comprises a pair of separator plates (222, 224) and a pair of fluid distribution layers (218, 219) interposed between the separator plates. At least one of the fluid distribution layers comprises a sealing region (240) and an electrically conductive, fluid permeable active region (230), and a preformed sheet material extending into each of the sealing region and the active region. An ion exchange membrane (214) is interposed between at least a portion of the fluid distribution layers, and a quantity of electrocatalyst (220, 221) is interposed between at least a portion of each of the fluid distribution layers and at least a portion of the membrane, thereby defining the active region. Compression of the preformed sheet material by urging of the pair of plates towards each other renders the at least one fluid distribution layer substantially fluid impermeable in a direction parallel to the major planar surfaces, in the sealing region. The performed sheet material included in the at least one fluid distribution layer thus has intrinsic sealing capability.      This approach reduces or eliminates the need for separate gaskets or sealing components and integrates several functions, such as sealing, fluid distribution, and current collection, in a single layer.
Patent CA-2288623-A1 (CA)
Inventor: HOEHN ANDREW F
IPC: C08F6/00
Filed: 1998-05-13
Abstract: A process for polymer deformulation by solvent solution filtration begins by including formulated polymers and/or polymer products in a recycle stream. The formulated polymer products include a quantity of soluble polymers and/or insoluble polymers, soluble and/or insoluble colorants, formulations and additives. The recycle stream is placed in a solvent, taking the polymer and formulations into a solvent/polymer solution. Next, the solution is processed through a filtration stage. A quantity of mineral filter aid particles are then added to the solution to adsorb formulations contained in the solution. One of the mineral filter aids must be some form of carbon, preferably activated carbon. Other mineral filter aids may include diatomaceous earth. The solvent/polymer solution is then subjected to an additional polish filtration stage to remove substantially all of the mineral filter agents and associated formulations. Following filtration, a quality check is performed on the solvent/polymer solution to determine whether additional filtering of the solution is required. If additional filtering of the solution is required, the filtering process is repeated. If no additional filtering is required, the deformulated polymer is separated from the solution, and the deformulated polymer is allowed to dry.

Title: Automatic telecommunications link identification system
Inventor: KOAY HELENA G
IPC: H04M3/00
Filed: 2000-01-21
Abstract: A telecommunications network in accordance with the principles of the invention includes one or more controllers that automatically determine the physical interconnectivity between at least two ports adjacently situated in different network elements. Each end-point, that is, each port, has a unique identification. In an illustrative embodiment, upon the occasion of a network modification, such as the addition of a port to the network, the initiation of a port, or reconfiguration of a link, the two ports attached to a communications path to form a link exchange their "view" of the link. That is each port sends an identification message to the other port. Each of these messages includes the identification of the sending port and the presumed identification of the receiving port. If at first the ports don't agree, the receiving port updates its view of the link. This process is repeated until both ports agree on the identification of each port within the link.

Title: Integrated deethanizer ethylene fractionation column
Inventor: STORK KARL
IPC: C10G7/00
Filed: 2000-03-06
Abstract: An integrated deethanizer and ethylene fractionation column and process for separating a feed stream comprising ethylene, ethane and C3+ is disclosed. A single shell houses a refluxed upper portion and a lower portion of the column. A generally vertical wall partitions the lower portion of the column into a deethanizer section and an ethylene stripper section. The upper column portion is used as the absorption section of the ethylene fractionator. The feed is supplied to an intermediate stage in the deethanizer, and the deethanizer is operated at a lower pressure (and correspondingly lower temperature) matching that of the ethylene fractionation. The design allows the use of one slightly larger column in place of the two large columns previously used for separate deethanization and ethylene fractionation.
