Title: Inerting method for preventing and extinguishing fires in enclosed spaces
Inventor: WAGNER ERNST WERNER
IPC: A62C2/00
Filed: 1999-02-17
Abstract: The invention relaxes to an inerting method for reducing the risk of and for extinguishing fires in enclosed spaces, and to a device for carrying out this method. The aim of the invention is ensure that a fire can be extinguished effectively whilst keeping the storage requirements for the inert gas cylinders to a minimum. To this end, the oxygen content of the enclosed space is reduced to a set base inerting level and in the event of a fire, is quickly reduced further to a set complete inerting level. The device for carrying out this method is equipped with an oxygen-measuring device in the space being monitored, with a first system for producing the oxygen-expulsion gas or for extracting the oxygen from the space being monitored, a second system for rapidly feeding an oxygen-expulsion gas into the space being monitored and a fire detection device for detecting a fire characteristic in the air in the enclosed space. A control unit is also provided. This control unit sends a base inerting signal to the first system in accordance with the oxygen content of the air in the enclosed space being monitored and a complete inerting signal to the second system in accordance with a detection signal from the fire detection device.

Title: Power saving circuit and method for driving an active matrix display
Inventor: JEONG DEOG-KYOON
IPC: G09G3/36
Filed: 1998-09-04
Abstract: Switches and capacitors are efficiently used to passively change the voltage level on column electrodes without active driving by the column driver circuit. This significantly reduces the power needed by the column driver circuit to drive voltages of alternating polarity onto the column electrodes. In this way, significant power is saved in both the pixel inversion and the row inversion schemes. The average power savings of various of the embodiments exceeds 50 % compared with a simple conventional implementation of a column driver circuit. Another aspect similarly reduces the power used by the column driver circuit in the back plane switching scheme.

Title: A valve for a tank and especially for a flow control arrangement having a plurality of fluid storage tanks
Inventor: PERVAIZ MUHAMMAD
IPC: F16K21/02
Filed: 2000-09-28
Abstract: A fluid flow control valve having a cam disposed near an opening of a fuel passage. The cam is operable to be rotated about a shaft by the action of a float. As a fluid level in a tank changes, the cam rotates from an open position remote from the opening to a closed position (as illustrated) proximate the opening. A gap remains between the cam and the opening, thereby allowing the fluid level to be drawn down to the bottom of opening. Float has a generally wedge shaped cross-section to minimize the effect of wave action in the fluid.
Patent CA-2322390-A1 (CA)
Inventor: BORING DAVID ERIC
IPC: F24C3/00
Filed: 2000-10-05
Abstract: A low carbon monoxide fire log includes an impingement surface fabricated from a low density refractory material. The low density impingement surface does not cool the impingement flame when the impingement flame is impinged on the surface. The hotter flame results in complete combustion and less carbon monoxide. The low density impingement surface may be a refractory fiber blanket material, a refractory fiber cloth material, or a low density particulate material. The low carbon monoxide log allows a log set to be fabricated in a single piece because the low carbon monoxide levels increase the manufacturing tolerance.

Patent CA-2327526-A1 (CA)
Inventor: ZHANG XUEJUN C
IPC: C12N9/12
Filed: 1999-05-06
Abstract: Structural information about the streptokinase-micro plasminogen complex has been used to identify the part of the streptokinase structure not involved in plasminogen complexation or activation. These nonessential portions can be modified to reduce antigenicity, for example, by changing the nonessential portions of streptokinose to more human-like polypeptide portions ("humanization of streptokinase"). One way this can be done is to compare the nonessential portion to a structural database of human proteins to find similar structures. Then the streptokinase nonessential structural part is replaced with the human structural part such as by genetic engineering of a mutant encoding the individual streptokinases, which is then expressed in a bacterial host such as E. coli. Alternatively, the nonessential portions can be removed or truncated to simplify streptokinase to a smaller molecule which retains plasminogen activation activity. Such smaller proteins should have reduced antigenicity and be cheaper and easier to produce. The modified streptokinases are useful in treating clotting disorders.

Title: Space-time processing for multiple-input, multiple-output, wireless systems
Inventor: FOSCHINI GERARD JOSEPH
IPC: H04B7/08
Filed: 2000-12-05
Abstract: In a MIMO system the signals transmitted from the various antennas are processed so as to improve the ability of the receiver to extract them from the received signal even in the face of some correlation. More specifically the number of bit streams that is transmitted simultaneously is adjusted, e.g., reduced, depending on the level of correlation, while multiple versions of each bit stream, variously weighted, are transmitted simultaneously. The variously weighted versions are combined to produced one combined weighted signal. The receiver processes the received signals in the same manner as it would have had all the signals reaching the receive antennas been uncorrelated. The weight vectors may be determined by the forward channel transmitter using the channel properties of the forward link which are made known to the transmitter of the forward link by being transmitted from the receiver of the forward link by the transmitter of the reverse link or the weight vectors may be determined by the forward channel transmitter using the channel properties of the forward link and the determined weight vectors are made known to the transmitter of the forward link by being transmitted from the receiver of the forward link by the transmitter of the reverse link. The channel properties used to determine the weight vectors may include the channel response from the transmitter to the receiver and the covariance matrix of noise and interference measured at the receiver.

Title: Mechanical heart valve
Inventor: STEINSEIFER ULRICH
IPC: A61F2/24
Filed: 1999-06-02
Abstract: The present invention relates to an improved trileaflet mechanical heart valve (100) and an improved leaflet (110) for use with such valve. The valve (100) and leaflet (110) of the present invention provide improved flow characteristics, minimize blood clotting behind the leaflets, and provide more natural opening and closing times. The valve includes a valve housing (105) which contains pivot/hinge mechanism (130, 200, and 300) for allowing rotation of and retention of the leaflets (110). The valve housing (105) also includes windows or openings (125) which allows for complete washing of the pivot/hinge mechanism (130, 200, and 300) as well as the leaflets (110). The novel leaflets (110) are air-foil-like having a complex S-shaped curvature on their outer surface. This novel geometry, when combined with the location of the leaflet's pivot axis, causes a tendency for the leaflet (110) to rotate towards the closed position. Thus, the leaflet (110) begins to close much earlier than a conventional leaflet and is substantially closed before the flow reverses, similar to the function of a natural valve.
