Filed:

Oct 24, 2007

Appl. No.:

11/923343

Inventors:

Eric M. Arnett - Granger IN, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F16K 31/64

US Classification:

137468, 60 39281, 60730, 137554

Abstract:

A metering valve assembly is provided for metering a fluid. The metering valve assembly includes a position sensor, metering valve, and a thermal compensation mechanism. The metering valve includes a valve housing having a flow passage therethrough, and a valve element movably mounted within the valve housing. The thermal compensation mechanism is coupled between the position sensor and the valve element and configured to adjust the displacement of the position sensor relative to the valve element as a function of fluid temperature.

Honeywell International Inc. - Morristown NJ

International Classification:

F04B 49/00

US Classification:

417304, 417296, 417300, 417308

Abstract:

A flow prioritizing system includes a regulating valve and a flow prioritizing valve. The regulating valve receives a first portion of the fluid supplied from a fuel supply pump, and is responsive to a control pressure to selectively allow or prohibit flow to secondary loads. The flow prioritizing control valve is responsive to fluid pressure representative of delivery pump discharge pressure to control the control pressure to which the regulating valve is responsive.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F16K 31/02

US Classification:

2511292, 25112915

Abstract:

A torque balance servo is provided for use in conjunction with a fluidly-controlled device. The torque balance servo includes a pivoting table assembly and an electromagnetic force bias mechanism. The pivoting table assembly includes: (i) a pivoting table configured to pivot about a rotational axis, and (ii) a roller assembly mechanically coupled to the fluidly-controlled device and contacting a surface of the pivoting table. The electromagnetic force bias mechanism is disposed proximate the pivoting table assembly and configured to exert a variable torsional force about the rotational axis of the pivoting table.

International Classification:

F04D 27/00

US Classification:

415 1, 415 18, 415125, 415160, 91 45

Abstract:

In one embodiment a system is disclosed that includes an actuation device coupled with a turbomachinery mechanism. The actuation device can include multiple fluid pathways and a valve to alternatively place each of these pathways in fluid communication with a supply port while another of the pathways is in fluid communication with a return port to selectively move an actuation member along a range of travel. A brake valve may also be included to provide pressurized fluid to the actuation member when the actuation device is in an on condition and divert at least a portion of the pressurized fluid away from the actuation member through another pathway when the actuation device is in an off condition. A fluid-powered brake is coupled to this further pathway to selectively apply braking force to the actuation member in response to the diverted pressurized fluid.

US Classification:

415 1, 4151213, 415150, 415202, 415901

Abstract:

In one embodiment, a fluid driven actuation system is provided having a turbine and an actuation member with cooperating surfaces. In one form the fluid is fuel. The turbine may move when fluid is flowed through the actuation member thereby causing the actuation member to move by action of the cooperating threaded surfaces. A movable nozzle may also be provided to direct fluid flowing through actuation member and may be used to cause the turbine to move. A spring may be provided to create a biasing force in the nozzle.

International Classification:

G01J 350
H01J 516
H01J 4014

US Classification:

250226

Abstract:

A method of encoding and decoding a binary modulated light spectrum to recover encoded intelligence. The method enables reliable and accurate decoding of wave division multiplexed data. The method incorporates a step of encoding data and a step of decoding the data which employs a photo-detector array. This method of encoding and decoding data compensates for variations in signal level, spectral position and spectral width with no degradation in reconstructed data.

Assignee:

Allied-Signal Inc. - Morristown NJ

International Classification:

G01J 350
G01D 534

US Classification:

250226

Abstract:

A method of decoding spectral data that has been encoding by modulation of a spectrum of light to produce data bits from a source using on/off and off/on transitions to represent each data bit. A start data bit with a constant width precedes each segment of light representing the data bits. The intersection of the output of spectral detectors and a hysteresis curve determines a transition through which information is obtained from the encoded data.
