Title: System and method for boarding and letting off passengers in trains efficiently so that the train does not have to stop at the stations
Inventor: MAYER YARON
IPC: B61K1/00
Filed: 2003-06-20
Abstract: One of the biggest problems of efficiency in trains is the time wasted for boarding and letting off passengers at the stations. Since trains carry a very heavy mass, typically it can take a few minutes for the train to decelerate and come to a full stop and a few minutes to wait till all the passengers who want to get off or board the train finish boarding or exiting, and then again a few minutes to finish accelerating, and thus each stop at a station can typically slow down a train by 5-15 minutes. This is especially noticeable in fast trains, such as for example trains that go at 150 Mph or more, so that the same trip with the same type of train can take for example 3.5 hours when no or almost no stops are made on the way and 7.5 hours if the trans stops at every station. The present invention solves the above problem by enabling passengers to board the train or to get off at each desired station without needing the train to stop or even slow down, based on using an intermediary device of one or more coaches that are used for getting on or off the train while the train is traveling preferably at full speed. The invention solves various problems involved in implementing such a solution.

Title: Method of treating tumor and consignment system of proliferating and processing activated lymphocytes to be used in parallel to pdt
Inventor: OKITA KIWAMU
IPC: A61K35/14
Filed: 2002-03-05
Abstract: A therapeutic method for enhancing an effect of treating tumor such as cancer wherein activated lymphocytes are administered within a definite period of time before or after the performance of photodynamic therapy (PDT). By administering activated lymphocytes in parallel to PDT, synergistic effects of the PDT and the administration of activated lymphocytes can be established. As a result, tumor such as gastric cancer can be remarkably efficiently reduced and destroyed. Moreover, an excellent therapeutic effect can be achieved on tumor showing no sensitivity to PDT alone. On the assumption of carrying out in parallel to PDT, the above therapeutic method of administering activated lymphocytes, which would not always impart cancer specificity, contributes to the destruction of tumor or improvement in the effect of preventing the enlargement thereof.

Title: Pneumatic control system for trailer container chassis latching
Inventor: EBERLING CHARLES E
IPC: B60T13/66
Filed: 2002-03-14
Abstract: A control system for a container chassis latching assembly of a trailer provides for initial pressurisation of the latching assembly via the trailer supply line. Once a trailer reservoir is sufficiently charged, pressure is maintained for the latch assembly by the trailer reservoir. A preferred control valve interconnects the supply line with a supply port of the valve to provide the desired pressure at a delivery port. A control port of the valve is connected with the trailer reservoir and shuts off this flow once the trailer reservoir has reached a predetermined pressure. Thereafter, the latch assembly is maintained via air supplied from the trailer reservoir.

Patent CA-2448221-A1 (CA)
Inventor: ADAMS JOHN LEONARD
IPC: H04L47/31
Filed: 2002-06-14
Abstract: A packet network node and method of operating a packet network node are disclosed. Conventional packet network nodes react to congestion in the packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In embodiments of the present invention, communication sources precede communications with a start packet which contains a communication identifier also carried within subsequent packets of the communication. The packet network node makes an entry in a vulnerable communications table (6.4) on receipt of such a start packet. After an amount of time, and often before the cessation of a communication, such entries are removed from the vulnerable communications table. On the onset of congestion, the packet network node disclosed herein deletes packets in communications identified in the vulnerable communications table. This provides a congestion alleviation method which is less annoying to users since communications that have been in existence for longer are less susceptible to component packets being deleted.

Title: Method for avoiding air pockets in a joint between two structural components
Inventor: WEISSER TILMAN
IPC: B29C65/52
Filed: 2004-05-03
Abstract: When two structural components are to be joined, for example, when an aircraft skin section is to be secured to a stringer by an adhesive bonding, it is important that the joining surface areas are plane to avoid the formation of air inclusions in the joint because air inclusions weaken the mechanical strength of the joint. Thus, a surface topography that is not plane must be smoothed out prior to the joining. For this purpose the surface areas to be joined are optically scanned to provide topographical information for each surface area that needs to be smoothed out for providing a plane joining surface. The topographical information is processed to ascertain the configuration and volume of the surface topography that needs to be filled with a filler material to produce a plane surface or at least a smooth surface without hills and dales. A respective control signal is produced and fed to a dosing equipment which supplies the exact volume of filler material required for planing or smoothing the surface topography. When smoothing is completed the two components are ready for joining for example by the application of pressure and heat to the filler material.
