Title: Cardiac pacemaker lead with swaged distal electrode
Inventor: DAS STEPHEN D
IPC: A61N1/05
Filed: 1999-03-05
Abstract: A cardiac stimulator lead (10) including a connector (16) for connecting to a cardiac stimulator and a flexible tubular sleeve (12) that has a first end coupled to the connector and a second end. An electrode (20) has a proximal end that is inserted into the second end of the sleeve. An annular member (25) is disposed around the proximal end of the electrode (20) and around the second end of the sleeve (12) and is deformed to clamp the second end to the proximal end.

Title: Novel membrane fusion proteins derived from poikilothermic reovirus
Inventor: DUNCAN ROY
IPC: C07K14/14
Filed: 2000-12-01
Abstract: In accordance with the present invention, a family of membrane fusion proteins and polynucleotides encoding the proteins have been identified. The proteins and polynucleotides are derived from the family Reoviridae. Two membrane fusion proteins have been isolated from reoviruses isolated from poikilothermic hosts: the p14 protein from reptilian reovirus (RRV) isolated from python, and the p16 protein from aquareovirus (AQV) isolated from salmon. The genes encoding these proteins have been cloned and sequenced.      Analysis of the amino acid sequences of these proteins show that both lack the typical fusion peptide motif found in other membrane fusion proteins. Expression of these proteins in cells results in cell-cell fusion.

Title: Packet switched mobile radio telecommunications system with more effective hard handover
Inventor: COSTA MAURO
IPC: H04L12/56
Filed: 2000-11-02
Abstract: In a packet switched mobile radio telecommunications system such as UMTS or GSM, on hard handover of a mobile 18 a target RNC 24 requests a direct link 36 to a serving controller 22, which sends uplink frames from the mobile 18 both to the TRNC 24 and to the core network 10; the core network 10 sends downlink frames to the TRNC 24. The TRNC decides when to complete the handover, and rebuilds frames when necessary.

The mantissas of the extended-precision result D are provided such that the high order word mantissa is stored to double precision registers.
Patent CA-2330020-A1 (CA)
Inventor: SHIRER LEE A
IPC: A61F2/50
Filed: 2000-12-29
Abstract: A method and apparatus for forming an impression of a socket used in a prosthetic device. The impression is formed using a blank formed of a material which is malleable at low temperatures. The blank is inserted inside the socket and heated so that the blank assumes a molded shape which conforms to the shape and size of the socket. The molded blank is then cooled and removed from the socket.  The blank material has a sufficient flexibility to allow the molded blank to deflect or bend significantly during removal yet return to its molded shape. The molded blank may then be used to form a new socket.

Title: Communications network
Inventor: RIZZO MICHAEL
IPC: H04L12/14
Filed: 1999-06-04
Abstract: In a communications network, which may be a federated network such as the Internet, a tariff is distributed via the network to customer terminals. At each terminal a charge for use of the network is calculated by using the tariff. Different tariffs may be communicated for different services and a respective tariff may be varied depending upon the operational condition of the service. Different tariffs may be calculated for different customers and the tariffs may be varied in dependence upon the loading of network resources and different tariffs may have different volatilities. Part of the traffic from a user to the network may be sampled and the status of the user may be amended when a discrepancy is detected between the sampled parameters and the contracted parameters in the user's contract.

Patent CA-2342248-A1 (CA)
Title: Foaming drain cleaner
Inventor: AJMANI INDERJEET K
IPC: C11D1/90
Filed: 1999-07-08
Abstract: A composition is provided comprising two liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent and a second liquid preferably includes a peroxygen agent. As the two liquids are initially separated, the hypohalite generating agent can be maintained in an environment free of peroxygen agent and otherwise conducive to their cleaning activity and stability up to the time of use. When the two liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe. The expanded foam contains an excess of the hypohalite, which acts to clean the drain. A method of cleaning drains is provided which comprises the step of pouring into a drain at least one liquid which generates foam in situ, the foam characterized by a density of at least about 0.1 g/ml, a half life of greater than about thirty minutes, a foam:liquid volume ratio of at least 1:1, and wherein the foam contains a cleaning-effective amount of a drain cleaning active.

IPC: A47L5/36
Filed: 2001-07-25
Abstract: An automatic discharge assembly for use with vacuum cleaner is disclosed. The vacuum cleaner has a tank defining an interior having an inlet for receiving liquid material and an outlet for discharging liquid materials, and a vacuum source for selectively generating a partial vacuum in the tank interior. The automatic discharge assembly comprises a valve housing defining a liquid discharge path having an inlet adapted for fluid communication with the tank outlet and an outlet for directing liquid material discharge. A pressure-responsive flapper valve is pivotably connected to the valve housing, the flapper valve being moveable between a closed position, in which the flapper valve obstructs the liquid discharge path, and an open position, in which the flapper valve allows fluid flow through the liquid discharge path. The flapper valve moves to the closed position when vacuum is present in the tank interior, and to the open position under a mass force of the liquid material inside the tank when a pressure in the tank interior is substantially the same as an atmospheric pressure outside the tank.
