Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

G01D 5/34

US Classification:

25023113

Abstract:

An optical sensor system and method for determining the position, displacement and/or angle of a member (for example, a seal plate or valve gate) within a system (for example, a valve assembly in an aircraft turbine engine system or environmental control system). The system has, in one embodiment, a controller in communication with an encoder via a fiber optic line or similar light transmitter and the encoder further has an optically layered element. The optically layered element has at least one coating whose optical characteristics vary over the angles (or distance) of interest to provide feedback based on the position displacement and/or angle of the valve member. The system may communicate and/or be controlled by a computing system via a data communication network.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

C21B 3/00
F27D 5/00

US Classification:

266274, 432258

Abstract:

Tools and methods are provided for use in a process for sintering a metal injection molded body where the body comprises a material and having a first end, a second end, and a flowpath extending therebetween, the flowpath having a diameter. The tool assembly comprises an insert and an endcap. The insert is configured to be disposed in the body flowpath and has an inner surface, an outer surface, a first end, a second end, a channel, a slot having a width, an inner diameter and an outer diameter. The endcap is configured to be inserted at least partially into the channel at the insert first end when the slot width is increased, and at least a portion of the endcap has an outer diameter that is substantially equal to or larger than the insert inner diameter.

Abstract:

Improved drying, binder evaporation, and sintering processes which may be used in conjunction with specialized sintering tools to provide for the geometrically stable sintering of large, complex, metal injection molded preform parts or flowbodies. The improved process includes a three-stage drying process, a single stage binder evaporation process, and a two-stage sintering process.

US Patent:

50465279, Sep 10, 1991

Filed:

Mar 6, 1991

Appl. No.:

7/665390

Inventors:

John N. Tervo - Scottsdale AZ

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

F16K 1503

US Classification:

1375278

Abstract:

A butterfly-type check valve (8) in which a valve plate (18) moves translationally relative to a pivot axis (90) and incident to rotational movement (118) of the plate. The translational movement is effected by mechanical links (38, 40) which are pivotally secured to the plate and a support assembly (52, 54, 56, 76, 78). The translational movement is guided by two trunnions (30, 32) pivotally secured to the support assembly, and two rods (20, 22) rigidly secured to the plate and extending through the trunnions.

John N. Tervo - Scottsdale AZ

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

F16K 122

US Classification:

137 1

Abstract:

A method for facilitating control of a butterfly valve, butterfly valves (40, 180) adapted for use with the method, and a fluid system (242) incorporating such valves are disclosed. All three use or incorporate butterfly valve structure that provides for relative translational movement (246) between the valve plate (42, 182, 248) and a pivot axis (232) in order to alter fluid dynamic torque exerted on the valve plate.

Inventors:

John N. Tervo - Scottsdale AZ

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

F16K 1503

US Classification:

1375278

Abstract:

The invention is a butterfly-type check valve (8) wherein the valve plate (18) moves translationally relative to a pivot axis (90) and incident to its own rotational movement. The invention employs biasing means (102, 104, 108) for initiating movement of the valve plate when the latter is at a closed rotational position, thereby eliminating the need for a pilot valve.
