Title: Method for extending the switching matrix of a communication system without interruption
Inventor: STEINIGKE KLAUS
IPC: H04L49/111
Filed: 1999-11-17
Abstract: If the connection capacity of a communication system is to be extended, the switching matrix, as central part, needs to be enlarged in particular. In the prior art, this is done by interrupting operation and fully disconnecting the switching matrix. After the changeover, the interrupted connections need to be set up again, which is associated with a large amount of effort in the case of ATM connections, for example. The invention provides a remedy for this by reserving space for the routing addresses of the largest extension stage both in the header translation table of the interface devices and in the cell header of each ATM  cell, and by providing a system split which is used to replace the old switching matrix assemblies with new switching matrix assemblies in steps, the paths via the new switching matrix assemblies, insofar as they lead to the same output-side interface devices as via the old switching matrix assemblies, being addressable using the same routing addresses.

Title: Method and apparatus for reducing dissipation rate of fluid ejected into boundary layer
Inventor: BABENKO VICTOR V
IPC: F17D1/08
Filed: 1999-12-30
Abstract: Skin friction reduction on a surface moving relative to a fluid can be obtained by ejecting a polymer-water mixture/solution (9) into the boundary layer. The efficacy of the ejected polymer-water mixture/solution is closely related to polymer dissipation out of the boundary layer and conditioning (i.e., lengthening, unwinding or stretching) of the polymer molecules by liquid shear forces immediately before ejection. The invention is a method and apparatus for conditioning and ejecting a polymer-water mixture/solution (9) that improves drag reduction characteristics of the mixture/solution and maintains the mixture/solution in the boundary layer for as long as possible. By improving the drag-reduction characteristics of the polymer-water mixture/solution and by extending the time it remains in the near-wall region, the ejector can increase the performance and reduce the volume and storage requirements of a drag-reduction system.     Although this invention was intended for polymer-water mixture/solution ejection, it can be used for ejection of any substance into a flowing fluid.

Abstract: A method of testing a volatile liquid tank farm together with a vapour recovery system, to collect vapour from the tanks at the time of re-filling them with volatile liquid. The tank farm has individual fill-pipes (13) for each tank (10) with each fill-pipe outlet below the normal minimum liquid level in the tank and each tank having a vent-pipe (11) connected to a commo n manifold (25). To perform the test, the common manifold is closed to atmosphere and one side of a shut-off valve (17) is connected to the manifol d (25), a flow meter (20) being connected to the other side of the shut-off valve. Flow meters (22, 23) are coupled to all but one of the fill-pipes (13 ), the shut-off valve (17) is opened to allow liquid to be supplied to the remaining fill-pipe so as to increase the volume of liquid in the associated  tank, and the out-flow of gas or wet vapour from the common manifold (25) is  monitored for substantial correlation to the volume of liquid admitted to th e tank associated with the remaining fill-pipe. The method can be modified als o to allow the testing of individual tanks of a tank farm, where the vent-pipe s of the tanks individually vent to atmosphere, the test then being performed one at a time, on each tank.

Title: Engine power boost control system
Inventor: PIPHO MICHAEL JOHN
IPC: F02D31/00
Filed: 2002-03-01
Abstract: A power boost control system is provided for an agricultural vehicle with an engine which is normally governor controlled to run at throttle-selected constant engine speed up to a normal or rated engine speed. The power boost control system receives a road speed signal. Power boost is enabled if the sensed road speed is greater than an "on" threshold, above which is considered to be a transport speed. Power boost is disabled if sensed road speed is less than an "off" threshold, below which is considered to be less than a transport speed. When power boost is enabled, the controller will increase maximum power limits to above normal levels, so that, for example, the desired road or transport speed can be maintained as the vehicle goes up a hill.
