Appl. No.:

6/165432

Inventors:

William R. Spencer - Springdale OH
George F. Whitley - Madeira OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F16L 5500

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F01D 1708

US Classification:

415 48

Abstract:

A temperature sensor, for measuring the temperature of air flowing in a substantially annular path into a compressor stage of a gas turbine engine, is positioned in proximity to the inner diameter of the annular flow path forward of the compressor stage where the measured temperature of the compressor inlet air is reliable during periods of water ingestion as well as during dry operation.

Appl. No.:

6/007118

Inventors:

George R. Henry - Loveland OH
William R. Spencer - Cincinnati OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

G01M 1500

US Classification:

73115

Abstract:

An apparatus for detecting and indicating the occurrence of a gas turbine engine stall operates by sensing sudden changes in a selected engine pressure. When a sudden large decrease in the selected engine pressure indicative of a stall is sensed, a visual indication is provided.

Appl. No.:

8/131179

Inventors:

William R. Spencer - Springdale OH
Edwin K. Miller - West Chester OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F16K 122

US Classification:

251306

Abstract:

A butterfly valve comprises a butterfly vane including a radial notch. A seal groove is situated in the vane and a seal including tabs is disposed within the seal groove wherein the tabs are adapted to fit within the notch. The tabs are designed to bear against the sides of the notch. The notch is located on the high pressure side of the butterfly vane and in a position such that the butterfly housing limits the radial motion of the tabs when the valve is in the open position.

Appl. No.:

6/209363

Inventors:

William R. Spencer - Springdale OH
Dana D. Freberg - Middletown OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F16D 100
F16L 2500

US Classification:

403 4

Abstract:

The apparatus includes a first connecting link having a pair of axially opposing ends with one of the ends being coupled through a uniball to a drive portion of an actuator. A second connecting link includes a pair of axially opposing ends. One of the ends of the second connecting link is coupled to a driven portion, e. g. , a butterfly valve. Coupling means, including a mating plug and socket, is provided for adjustably coupling the remaining opposing ends of the first and second links. The mating plug includes four sides and one hole disposed eccentrically therethrough and parallel to the sides. The remaining end of the second link includes a socket for mating with the plug. The plug can be mated in eight different rotational positions with respect to the socket. At each of the eight different rotational positions, the eccentric hole is disposed in a position which determines one of a predetermined number of available couplings between the first and second links. The remaining end of the first link includes an opening therethrough for receiving securing means.

Appl. No.:

8/697807

Inventors:

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F02C 7232

US Classification:

60 39281

Abstract:

A fuel manifold staging valve is provided for use with aircraft engines. A first set of fuel nozzles is associated with a primary manifold, and a second set of fuel nozzles is associated with a secondary manifold. The valve opens on the basis of a constant ratio of fuel flow divided by compressor discharge pressure. The valve detects fuel flow by sensing the pressure drop across the fuel nozzles. This pressure drop is biased by a spring and compared to the compressor discharge pressure. When the ratio is correct for the geometry of the valve, the valve begins to open, allowing fuel to flow to the secondary manifold and associated fuel nozzles.

Inventors:

William R. Spencer - Springdale OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F16K 1106

US Classification:

137112

Abstract:

A maximum pressure selector device in which a valve ball is pressure actuatable in a chamber intermediate two cooperating valve seats of opposing input chambers. Positioned between the seats is a pair of orifices which connect the intermediate chamber to an output port. The orifices are of a predetermined size for allowing a predetermined maximum fluid flow rate therethrough for reducing surge flow. The valve ball is positioned in an encircling sealing arrangement centrally located in the intermediate chamber and is restricted to limited movement therein. The input chambers communicate with the intermediate chamber and thus with the output port, depending on the seating position of the valving element.
