Title: Medical infusion apparatus including safety valve
Inventor: SHEMESH ELI
IPC: A61M39/28
Filed: 1994-12-12
Abstract: A medical infusion apparatus includes a container for a liquid to be infused, tubing leading from the container to the subject to receive an infusion, a pump for pumping the infusion liquid via the tubing to the subject, and a safety valve connected in the tubing between the pump and the subject.

Patent CA-2182521-A1 (CA)
Inventor: DE FRANCESCO RAFFAELE
IPC: G01N33/576
Filed: 1995-02-14
Abstract: This is a method for reproducing in vitro the serine protease activity associated with the HCV NS3 protein, that comprises the use both of sequences contained in NS3 and sequences contained in NS4A. This method takes advantage of the ability of the HCV NS4A protein, or sequences contained therein, to act as a cofactor of the serine protease activity or more generally of the enzymatic activities associated with NS3. Optimal serine protease activity is obtained when NS4A is present in a molar ratio of at least 1:1 with NS3, NS3 and NS4A can also be incorporated in the reaction mixture as NS3-NS4A precursor, at this precursor will generate, by means of an autoproteolytic event, equimolar amounts of NS3 and NS4A. It is also possible to mutate the cleavage site between NS3 and NS4A in a precursor, so that NS4A remains covalently bonded to NS3. The sequences that do not influence the proteolytic activity of NS3 can subsequently be removed from said non-proteolyzable precursor. The invention also relates to a composition of matter that comprises sequences contained in NS3 and NS4A, and to the use of these compositions for the setup of an enzymatic test capable of selecting, for therapeutic purposes, compounds that inhibit the enzymatic activity associated with NS3. The figure shows plasmidic vectors used in the method to activate HCV NS3 protease in cultivated cells and in vitro.

Title: Structure and method for performing active injection mode filtering on an ac power system
Inventor: SUELZLE LARRY R
IPC: H02J3/01
Filed: 1995-06-05
Abstract: An active current injection device (117) generates and injects fundamental and non-fundamental frequency current components onto an AC power line (111). A current pump control circuit (132) receives an input signal which is representative of the power line voltage and generates a control signal which is used to generate a fundamental frequency current component which lags the line voltage by approximately 90 degrees.  This fundamental frequency current component is transmitted through an impedance (131) to the line (111), thereby causing a fundamental frequency voltage drop across the impedance (131). A damping control circuit (116/176) receives an input signal representative of the line voltage and generates as output signal having first and second components proportional to the line voltage and the line voltage rate of change, respectively. The output signal is used to generate an electronic load current component which loads non-fundamental frequency components of the line voltage.

IPC: B64C1/14
Filed: 1996-12-18
Abstract: A remote indication system for a cargo door which indicates the following conditions: Opened, Closed, Latched, Unlocked and Locked. The entire system, including sensors, is independent of the standard flight deck warning system.  This provides the required redundancy for the system so that direct observation is not required. An independent system from the standard f light deck warning system and/or the indication for each step of the process rather than just "open/closed" is utilized in the present cargo door control and indicating system.
Patent CA-2194525-A1 (CA)
Title: Water mist fire suppression device
Inventor: COX MATTHEW ALAN
IPC: A62C13/62
Filed: 1997-01-07
Abstract: A fire suppression device includes an enclosure having opposite end walls and a side wall joining the end walls to define a hollow chamber within the enclosure. An atomizing nozzle is operatively coupled to a first of the end walls and has anentrance portion adjacent the chamber and an exit in communication with the atmosphere outside of the enclosure. A frangible barrier is interposed between the nozzleentrance portion and the chamber and is responsive to a predetermined pressure for fracturing to permit communication between the nozzle and the chamber. A piston is located between the end walls and engaged about an inner periphery of the side wall to divide the chamber into two sections. A first of these sections, between the piston and the first end wall, is filled with a quantity of water and comprises a major fractional portion of the volume of the chamber. The piston is slidably moveable relative to the side wall in the direction of the first end wall in response to a force exerted upon the piston for exerting pressure upon the quantity of water for initially fracturing the frangible barrier and for thereafter delivering a water mist through the atomizing nozzle. A gas generator communicates with the second section for delivering high pressure gas to exert the force upon the piston, causing a fine mist to flow from the nozzle. As a variation, a conduit may extend from the nozzle to the second section, and the nozzle may include venturis extending between the first section and the conduit. The generated gas will flow through the conduit to further draw the water via venturi effect.

Patent CA-2202282-A1 (CA)
Title: Communications traffic management arrangement
Inventor: HOLMES GILLIAN
IPC: H04Q3/66
Filed: 1995-10-10
Abstract: An overflow service is provided in a virtual private network (VPN). Calls between private branch exchanges (1, 2) will be switched at a Service Switching Point (3) under the control of a Service Control Point (4). If the capacity of the VPN is already fully in use, then a further call attempt will trigger a congestion message. The Service Switching Point responds to a congestion message by routing the further call attempt onto overflow capacity, not normally allocated to the VPN. A maximum overflow capacity can be set, in accordance with a service level agreement between the network operator and the VPN customers, for instance by counting the number of re-route attempts. An advantageous embodiment provides a private branch exchange with a "hunt" group of lines for giving access to the network for a user. This provides a simple way of determining when capacity in the VPN is not available to provide a requested connection to a user.
