Abstract: A flight control pump system includes an electrical machine configured to operate in a motor mode and in a generator mode. A pump is operatively connected to be driven by the electrical machine in the motor mode. An overriding clutch is operatively connected to the electrical machine and to the pump to transfer torque from a main transmission to drive the pump and the electrical machine in the generator mode, and to decouple the main transmission from the electrical machine and the pump in the motor mode.

Abstract: The present invention addresses the processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency. In particular, the invention comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process subjects the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. The invention further comprises an apparatus for performing a multi-stage process of converting waste products into useful materials, and at least one oil product that arises from the process.

Abstract: Conversion of waste and other organic feedstock into sustainable energy, feed, fertilizer, and other useful products of reliable purities is accomplished using water, heat, and pressure. More specifically, the invention provides methods and apparatus that handle mixed streams of various feedstocks, e.g. agricultural waste, biological waste, municipal solid waste, municipal sewage sludge, and shredder residue, to yield gas, oil, specialty chemicals, and carbon solids that can be used as is or are further processed. Useful products can be diverted at various points of the process or internalized to enhance the efficiency of the system.

Abstract: Methods and apparatus for processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency are disclosed. In particular, multi-stage processes are disclosed to convert various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. Disclosed processes subject the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. Also disclosed are apparatus for performing multi-stage processes of converting waste products into useful materials, and at least one oil product that arises from the process.

In particular, the invention comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process subjects the feedstock to heat and pressure in a reducing environment accomplished by controlled addition of sulfur and sodium, separates out various components, then further applies heat and pressure to one or more of those components. The invention further comprises an apparatus for performing a multi-stage process of converting waste products into useful materials, and at least one oil product that arises from the process.

Abstract: The present invention includes an apparatus for separating particulates from a fluid in a suspension, comprising: a housing defining a frusto-conically shaped inner chamber with an inner wall, an inlet and a first outlet communicating with the chamber, and a second outlet; and a spinning assembly with a hollow interior mounted in the chamber, the assembly being shaped to define an annular gap with the chamber inner wall, the hollow interior communicating with the second outlet, and the hollow interior communicating with the annular gap for flow of fluid materials from the gap into the interior and out of the second outlet in response to rotation of the spinning assembly. The separator finds application in the preparation of waste products such as municipal sewage sludge for processes that produce useful materials including gas, oil, specialty chemicals, fertilizer, and carbon solids, in reliable purities and compositions, and with high energy efficiency.

Abstract: A hydraulic transfer valve system has a main valve selectively placing one of a primary and secondary hydraulic system in communication with a hydraulic load. A pilot valve provides a toggling action between the primary and secondary systems with respect to pressure changes in such systems.

Abstract: A helicopter collective control stick having a pilot grip positioned by a linkage assembly whose kinematics permits the control stick to occupy a small envelope and to have the pilot grip motion to be about a large radius. Our collective stick includes a biasing member to balance the control stick and linkage in the mid collective position and which provides a force gradient when the control stick is moved from the mid collective or trimmed position. Further, our collective stick is operable in concert with the full authority side arm controller to operate in either a tracking or a command mode.
