Power floating production and ship propulsion supported by gyroscope and energized by seas

To access the inexhaustible energy source like seas and oceans we need to learn how to convert its wave motion to the customized power for our ships, for our existing littoral settlements and our future ocean settlements. Here is an attempt to develop method of the conversion the wave energy to power with floating means based on a gyroscope strong capability to resist against the outer force moment trying to tilt it to any side.The gyroscope is used as the fulcrum torque dynamic supporting instead traditional static base used in the issued devices. Alternate force moment created by the waves and transmitted to the gyroscope (via the floating body and the wave energy converter) inducts alternative gyro precession so as the gyroscope axis hesitates about mean position. This is important because it allows the gyroscope to keep dynamic fulcrum torque in unlimited time.The few gyroscope precession control devices and methods have been developed to compensate other reasons enforcing the mean gyro axis to drift from initial plumb.Also here are developed the new ship architecture with the separated floating gyro section. The wagging propulsor driven by the pitching and with strokes amplified by the fulcrum gyro section, the spring moment generator for the gyroscope drift compensation, non gyroscope floating power station able to derive, convert, accumulate and transmit wave energy to consumer also have been developed here.

Cycling switch valve under well

The invention discloses a cycling switch valve under a well. The cycling switch valve under the well is designed to satisfy various technological requirements of high-pressure water injection well working under pressure. A cycling locking mechanism is designed inside a valve to enable the cycling locking mechanism to smoothly achieve unlimited times of cycling opening and closing movements of the valve through pressure inside an oil pipe on the ground. Opening and closing of the valve are only controlled by pressure difference between oil and a sleeve pipe and oil pipe flow rate, and have nothing to do with formation pressure, and therefore the cycling switch valve under the well can bear larger formation pressure, and then reliable sealing and plugging of the oil pipe are achieved. Due to the fact that a self-sufficient type lubrication system is arranged in the valve, lubricating oil can be supplied timely, so that a reversing part of the cycling switch valve under the well is enabled to work in a good environment, and service life is prolonged. Reversing pressure difference and flow rate of the cycling switch valve under the well can be set through the change of the dimensional coordination of parts inside the cycling switch valve under the well, and therefore the cycling switch valve under the well is enabled to be applied to field operation within areas with different formation pressure.

An improved method and system for layering RPC communications on top of an HTTP transport. An RPC data stream of individual request / reply packets is mapped to HTTP primitives, and RPC requests are mapped to one large, HTTP, POST-like request (IN channel). Corresponding replies are mapped to another large, HTTP, GET-like request (OUT channel). The client establishes the IN channel and OUT channel as simultaneously open connections with a large content-length for each. Before the content-length is exhausted, the client and server open a new IN or OUT channel while the corresponding channel is still alive, so that there is always at least one opened IN or OUT channel available. If traffic is too infrequent, the client keeps the connection alive so that it will not be closed for being idle. This provides a bi-directional virtual connection that remains open for an unlimited time for tunneling unlimited amounts of RPC traffic.
