An endwall treatment for a gas turbine engine having at least one rotor blade extending from a rotatable hub and a casing circumferentially surrounding the rotor and the hub, the endwall treatment including, an inlet formed in an endwall of the gas turbine engine adapted to ingest fluid from a region of a higher-pressure fluid, an outlet formed in the endwall and located in a region of lower pressure than the inlet, wherein the inlet and the outlet are in a fluid communication with each other, the outlet being adapted to inject the fluid from the inlet in the region of lower pressure, and wherein the outlet is at least partially circumferentially offset relative to the inlet.

A switching node for transferring packets, each including a destination address, in a network includes a plurality of input port modules, a plurality of output port modules and a switching fabric, including a packet meta-data processor and a packet switch. Each input port module is connected to a communication link for receiving packets thereover, and each output port module is connected to a communication link for transmitting packets thereover. Each input port module, upon receiving a packet, buffers the packet and generates a meta-data packet therefor identifying the output port module that is to transmit the packet and packet identifier information, and provides it to the packet meta-data processor. The packet meta-data processor receives the meta-data packets generated by all of the input port modules and operational status information from all of the output port modules and for each output port module, processes the meta-data packets received from all of the input port modules in connection with the operational status information to determine whether the packet should be passed or dropped. If the packet meta-data processor determines that a packet associated with a meta-data packet is to be dropped, it will notify the input port module in which the packet is buffered, which, in turn, will discard the packet. On the other hand if the packet meta-data processor determines that the packet associated with the meta-data packet is not to be dropped, it will enqueue the meta-data packet for the associated output port module. Each output port module retrieves meta-data packets from its respective meta-data packet queue maintained therefor by the packet meta-data processor. For each meta-data packet retrieved by an output port module, the output port module will request that the input port module identified in the meta-data packet transfer the packet identified in the input port module thereto through the packet switch. When the output port module receives the packet, it will transmit it over the communication link connected thereto.

Disclosed herein is a horizontal boring apparatus which is comprised of a remotely controlled drilling tool lowered from a self-contained vehicle into a previously drilled vertical shaft. The tool mills away a 360 degree band of metal casing adjacent to the desired area to be bored, and extends a hydraulic powered rotary drilling tool into the formation by extending and retracting a telescoping base while alternating stabilization of the base and bit end of the drilling tool much like an inch worm. The tool is designed to drill a 1 inch bore hole up to 150 feet in any direction, or several directions. The tool and tool housing contain instrumentation for sensing direction, inclination, density, and temperature.
