Abstract: ABSTRACT OF THE DISCLOSURE    A lubrication supply system for providing lubricant to the bearings and the gear box assemblies of a gas turbine engine includes a three stage control valve means inter-posed between the source or pressurized lubricant and the bearings.  The control valve is responsive to the engine speed which determines the level of pressurization of the pressurized lubricant.  The control valve may be in the form of a poppet valve including a housing having two co-axial, slidably mounted poppet members.  The first poppet is a spring-biased, start-up poppet member which controls the flow of lubricant through the control valve and out of a first aperture which is in communication with the bear-ings.  A spring-biased, modulating poppet member cooperates with the start-up poppet to control the flow of pressurized lubricant through second and third apertures which are in communication with a bypass conduit extending to the source of pressurized lubricant.  In operation, at shut-off engine speeds, for example, at or below 20% compressor speed, the start-up poppet closes off the first aperture and thus pre-vents flow of lubricant to the bearing package, thereby minimizing oil leakage from the bearing package and subse-quent engine smoking.  The pressurized lubricant flow through the control valve is bypassed through the second aperture and conducted via the bypass conduit for return to the source of pressurized flow.  As the engine speed in-creases, the start-up poppet is actuated to gradually open the first aperture to allow a limited flow of lubricant to the bearing package.  At engine idle speed, the start-up poppet and the modulating poppet are actuated to positions to provide a controlled amount of lubricant to the bearing package, with the excess lubricant being ducted through the second aperture and the bypass conduit back to the source of pressurized flow.  At the maximum power operating mode of the engine, the start-up poppet and the modulating pop-pet are fully actuated so that the first aperture is fully uncovered and a desired maximum flow is provided to the bearing package, with excess flow being provided through the modulating poppet and the third aperture to the bypass conduit for return to the source of pressurized flow.

Abstract: ABSTRACT OF THE DISCLOSURE   The centrifugal separator of this invention has an open top metal cylinder that spins about a vertical axis.  It has a hollow rotating shaft, an upper floor and a lower floor, an outer wall and an inner wall.  Fluid is pumped through the hollow shaft into a space between the floors, thence into a space between the walls and out through multiple jet holes in the inner wall.  This inner wall also has a series of horizontal rings on its inner surface.  The jet holes are circumferentially spaced between the rings. As materials are fed into the cylinder through a central feed pipe they are separated into denser materials and lighter weight materials through the turbulence created by the fluid jets.  In rotation, then, the lighter weight materials are spun off at the top of the cylinder and the denser materials collect between the rings.  After rotation is stopped, the collected materials are flushed out through a hole in the bottom of the cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE A monolithically integrated two-dimensional image sensor having an array of sensor elements disposed in rows and columns connected by respec-tive row and column lines.  A first readout of the sensor elements is under-taken and a charge packet representing the signal is formed by an oppositely doped semi-conductor region connected to the respective column lines which charge packet contains charge carriers generated as a result of incident radiation as well as noise signals.  A second readout of the sensor elements is undertaken for a short duration so that the charge packet generated as a result of the second readout represents only noise signals.  A difference-forming stage connected to the image sensor has a storage capacitor associat-ed with each column line for subsequently storing the two signals such that the voltage at the capacitor is displaced from a reference potential in an amount representing the difference between the two signals which thus provides a signal to a serial output device such as a charge transfer device which represents only charge carriers generated by incident radiation and is substantially noise-free.  The capacitors are connected to a reset device for preparing the difference-forming stage for the next readout sequence.

Abstract: ABSTRACT OF THE DISCLOSURE An energy conversion system utilizing gravity flow of water from a high elevation to sea level utilizing gravity to provide large pressure gradients in pipe lines as large quantities of water move from a high elevation at low pressure to low elevations at high pressure and then move under con-trolled conditions to low atmosphere pressure to operate electrical generators to generate large amounts of electrical current which can be effectively used for electrolysis separation of large volumes of hydrogen gas and oxygen from water and for other purposes.  The water can be used for direct consumption, irrigation in agriculatural areas, industrial use, fresh water aquaculture, stored in mass volume for future needs in aquifers or for any other purpose for which fresh water may be used for human needs either directly or indirectly with the fresh unpolluted water being easily conveyed into populated plains and coastal regions where such regions lay between wet mountainous regions and sea coasts or any other such area that would be at a sufficiently lower elevation to receive flow by gravity.  Large volumes of electrical energy may be produced by the flow rate and differential pressure across hydroelectrical turbine blades whether by in-line direct methods or turbine tip high leverage systems both of which are well-known in this field.  The separation of large volumes of hydrogen and oxygen gas by electrolysis methods provides a clean burning energy source which can be provided at various locations adjacent use sites.  The natural weather cycle provides a plentiful supply of water at high elevations in those geographical areas in which the present system is used and thus provides a self-perpetuating, closed loop system using gravity as the source of energy for the operation of the system.
