Appl. No.:

13/095563

Inventors:

Leora Peltz - Pasadena CA, US
Shawn H. Park - Cerritos CA, US
John E. Kuhn - Huntington Beach CA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

B05B 5/03
A61L 9/22

US Classification:

361227, 361228, 422 4, 422 22

Abstract:

A method and system are provided for decontaminating at least a portion of an object. A misting device is configured to discharge a cloud formed from a plurality of cloud droplets. At least some of the cloud droplets include a decontaminating agent. A spraying device is configured to discharge a stream including a plurality of stream droplets into the cloud. At least some of the stream droplets have an electrostatic charge. At least some of the cloud droplets are deposited on the portion of the object to facilitate decontaminating the portion.

Steven R. Kent - Downey CA, US
James S. Wells - Fountain Valley CA, US
John E. Kuhn - Huntington Beach CA, US

Assignee:

THE BOEING COMPANY - Chicago IL

International Classification:

B23P 19/04
F16K 15/00

US Classification:

137 1501, 137535

Abstract:

A rapid response self-closing pressure equalization vent employs a frame supported in a compartment divider and a movable vent portion having a periphery sealingly engaging the frame in a closed position. Multiple resilient extension elements are attached to the frame and engage the movable vent portion for even displacement around a periphery of the movable vent portion relative to the frame to an open position responsive to a pressure differential on the movable vent portion. The resilient extension elements retract upon equalization of the pressure differential to reseat the movable vent portion in the frame.

Appl. No.:

7/776607

Inventors:

Gary F. Ruff - Farmington Hills MI
John W. Kuhn - Bristol IN
Richard J. Wylie - Wabash IN

Assignee:

CMI International, Inc. - Southfield MI

International Classification:

B22D 2704

US Classification:

164122

Abstract:

A permanent metal mold (12) has a casting cavity (18) within which variable thickness molten metal articles (20) are cast. Portions (26) of the casting cavity walls (16) are formed oversized and lined with sand (44) to conform with the external size and shape of certain thick (46) and thin (48) sections of the cast article (20). The thickness of the sand liner (44) is reversely correlated to the thick (46) and thin (48) sections of the article (20) to cause these sections (46, 48) to cool at different rates in order to achieve an approximately equalized cooling time of these sections (46, 48). Other portions (50, 52) of the casting cavity walls (16) are formed bare of the sand liner (44) and conform with the external size and shape of other corresponding sections (54, 56) of the cast article (20). These bare metal portions (50, 52) can either be heated or cooled or both during casting in order to precisely control the cooling rates of these other sections (54, 56) of the cast article (20) and thus precisely control their resultant physical properties.

International Classification:

B22D 1908

US Classification:

164100

Abstract:

A method for metallurgically bonding cylinder liners (12, 12') within a cylinder block 14 of an internal combustion engine. The liners (12, 12') are cleaned (16) and their outer surfaces coated (18) with a low melting point cooling material (20) such as molten zinc forming a metallurgical bond therebetween. The coating (20) is allowed to solidify forming an outer oxidized layer (24) on the coating (20). The oxidized layer (24) is subsequently removed to expose an unoxidized outer surface (26) of the coating (20). The coated liners (12, 12') are then disposed within a casting mold and molten aluminum-based cylinder block material (36) is poured into the mold and about the coated liners (12, 12'). The molten cylinder block material (36) remelts the coating (20) on the liners (12, 12') and causes the coating to further alloy with the cylinder block material (36), whereupon cooling the cylinder liners (12, 12') are metallurgically bonded to the cylinder block (14).
