US Patent:

7156225, Jan 2, 2007

Filed:

Feb 22, 2005

Appl. No.:

11/064335

Inventors:

Tracey Jacksier - Lisle IL, US
Robert Benesch - Clarendon Hills IL, US
John Kuhn - Houston TX, US

Assignee:

American Air Liquide, Inc. - Houston TX

International Classification:

B65D 85/00

US Classification:

206 06

Abstract:

Compositions comprising a reactive gas and a matrix gas are disclosed, as well as articles of manufacture and methods of making the articles. The methods of manufacturing preferably employ zeolites to remove moisture from the reactive gas and from the matrix gas, and then combine the moisture reduced gases either in a container, or prior to filling a container, which has been previously vacuum-baked and passivated. The invention produces stable standard gas compositions having improved shelf-life.

Filed:

Oct 10, 1991

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).
