10/678792

Abstract:

The “Positive Displacement Turbine” engine (PDT) presented herein conforms to the classical definition of a heat engine. It operates in a thermodynamic cycle approximating the Otto, Diesel and Muller cycles but the primary motive force is developed at the pressure face of a blade rather than at the head of a reciprocating piston. The machine is therefore truly rotary with turbine-like characteristics, nevertheless, a fixed mass of air and fuel is compressed, ignited and expanded in a truly positive displacement process. Improvements offered by the present invention arise from the novel application of compression and expansion cycles being executed in adjacent and isolated chambers dynamically linked via internally mounted rotating combustion chambers hither too unseen as prior art. The means provided by this unique aspect of the present invention place it into a class of prime mover all of its own.

Abstract:

A user at a remote computer is provided access to a computer network by a remote access device coupled to the network. The remote access device receives from the remote computer a username which uniquely identifies the user on the network. The remote access device then obtains an internet protocol (IP) address from a server on the network, which server dynamically assigns the IP address based on the username. The IP address uniquely identifies the remote computer on the network, and it is needed by the remote computer to communicate on the network. If the user at the remote computer disconnects, or is disconnected, from the network and then subsequently attempts to re-gain access to the network by sending the same username to either the same or a different remote access device coupled to the network, that remote access device obtains the same IP address from the server. The user at the remote computer thus is provided with the same IP address by the server on the network when the user disconnects and then later reconnects to the network even if each of the two connections is via a different remote access device.

Abstract:

A system includes a fluid valve metering system which regulates a flow of a fluid within a gas turbine engine. The fluid valve metering system includes an inlet manifold, an outlet manifold in fluid communication with the inlet manifold, and multiple fluid conduits extending between the inlet manifold and the outlet manifold. Each respective fluid conduit of the multiple fluid conduits includes a respective fluid conduit valve of the multiple fluid conduit valves. Each fluid conduit valve regulates fluid the flow of the fluid through the respective fluid conduit. The fluid valve metering system also includes multiple differently sized orifices and a controller. The controller is coupled to the fluid valve metering system and programmed to monitor a usage of each orifice of multiple differently sized orifices, of each fluid conduit valve of multiple fluid conduit valves, or a combination thereof.

US Classification:

60741, 60742, 60776

Abstract:

A fuel metering valve system for use with a flow of fuel in a gas turbine engine may include a number of orifice plate lines, a number of differently sized orifice plates, and a number of orifice plate line valves. One of the orifice plate line valves opens and closes one of the orifice plates on the orifice plate lines.
