Abstract

A device is described that can sense changes in oxygen partial pressure and cause a corresponding mechanical displacement sufficient to actuate meters, valves and similar devices. A piston and cylinder arrangement contains a charge of crystalline metal chelate pellets which have the peculiar property of responding to variations in the oxygen content of the ambient atmosphere by undergoing a change in dimension. A lever system amplifies the relative displacement of the piston in the cylinder, and actuates the controlled valving device. This partial pressure oxygen sensing device is useful in controlled chemical reactions or in respiratory devices such as the oxygen demand meters for high altitude aircraft.

Automatic transmission having hydraulic and electronic control systems

Patent Furukawa, T; Mori, M

A shifting apparatus is described for a motor vehicle transmission which comprises: a shift actuator including shift shafts, cylinders, springs and select levers; the shift shafts effecting engagement and disengagement of transmission gears to accomplish shift ranges; each of the cylinders comprising one piston and two chambers defined by the piston, the piston being movable to three positions corresponding to the positions of the shift shaft and being actuated to one of the first or second position by applying working pressure to the chambers corresponding to each position; each of the springs urging the pistons to locate at a neutralmore »« less
Apparatus for reducing the toxic components in the exhaust gas of internal combustion engines

Patent Wessel, W

A fuel supply and metering valve assembly used for injection of fuel to an internal combustion engine includes a control pressure circuit which determines the restoring force on the movable member of the fuel metering valve. The magnitude of the control pressure, and hence the fuel quantity metered out by the valve assembly can be altered by the intermittent actuation of a pressure relief valve which controls a fluid bypass. The duty cycle of the intermittently acting bypass valve is controlled by a regulating device which responds to the indications of measuring transducers, for example an oxygen probe located inmore »« less
Piston engine employing oxygen

Patent Wallis, M

A piston engine is described which uses a flywheel rotor, in lieu of a crankshaft, driven hydraulically by the piston. One end of a plunger is connected to the piston, the other end being slidably disposed in an hydraulic cylinder. In the combustion mode, fuel and oxygen are injected and spark ignited, both by the same variable speed dc speed control motor. The piston-driven plunger displaces hydraulic fluid in the cylinder through a high speed orifice to impinge against spaced cavity surfaces formed along the periphery of the flywheel rotor, spinning the rotor. A slide valve is disposed in themore »« less
Fuel supply device for supplying fuel to an engine combustor

Patent Lindsay, M; Kerr, W

This patent describes a variable flow rate fuel supply device for supplying fuel to an engine combustor. It comprises: fuel metering means having a fuel valve means for controlling the flow rate of fuel to the combustor; piston means for dividing a first cooling fluid chamber from a second cooling fluid chamber; coupling means for coupling the piston means to the fuel valve means; and cooling fluid supply means in communication with the first and second cooling fluid chamber for producing a first pressure differential across the piston means for actuating the fuel valve means in a first direction, andmore »« less
Microprocessors control pipeline pressure

Journal Article Harris, J - Oil Gas J.; (United States)

This study presents a new concept in pipeline pressure limiting which in the past has been accomplished by pneumatic control equipment using gas from the pipeline as the power source. The concept uses a microprocessor-based system which controls pressure through electro hydraulically actuated valves having numerical solenoids as hydraulic pilots. This concept uses fluid under pressure (either air or hydraulic oil) is supplied by the system pump to a pair of directional control three-way solenoid valves. When deenergized, both valves apply pressure to the cylinders of the valves actuator, locking the position of the valve. When either of the directionalmore »« less
