US Patent:

6596122, Jul 22, 2003

Filed:

Dec 29, 2000

Appl. No.:

09/720698

Inventors:

Alexander Savitski - Liberty Township, Delaware County OH
Robert A. Grimm - Columbus OH

Assignee:

Edison Welding Institute, Inc. - Columbus OH

International Classification:

B29C 6500

US Classification:

1563042, 1562722, 1562728, 1563043, 156158

Abstract:

A method for production of simultaneous lap and butt joints directs electromagnetic radiation ( ) through a radiation transmitting material ( ) to an absorbing material ( , and ) that absorbs radiation ( ) with the generation of heat. The heat provides sufficient molten material in interfaces ( , and ) to fuse and bond: 1) pipe ends ( ) to each other in a butt joint ( ), 2) pipe end portion ( ) to sleeve ( ) in a lap joint ( ), and 3) pipe end portion ( ) to sleeve ( ) in a lap joint ( ). Use of a sufficiently clear material for sleeve ( ) allows visual inspection of joints ( , and ). Butt joint ( ) can be formed by conductive heating without absorbing material ( ) to provide a smooth interior bore useful for transporting high purity fluids without risk of absorbent contamination or debris and organism collection in gaps found in previous joining techniques.

Appl. No.:

5/809988

Inventors:

Bhupendra C. Trivedi - Worthington OH
Robert A. Grimm - Columbus OH
R. B. McConnell - Dublin OH

Assignee:

Ashland Oil, Inc. - Ashland KY

International Classification:

C07D23316

US Classification:

548347

Abstract:

Method for exhaustively alkylating the amine content of an imidazoline product prepared from a higher fatty acid and a dialkylene triamine wherein the protonated species formed in the course of the alkylation reaction are repeatedly neutralized, followed in each instance by reaction with an essentially equivalent amount of the alkylating agent based on the free amine present until the starting amine content of said product is predominantly converted to quaternary ammonium derivatives.

International Classification:

B23K 1302

US Classification:

219765

Abstract:

A process for obtaining long, continuous, thermoplastic welds on large structures. A series of tabs are used in pairs and especially in alternating, overlapping pairs to obtain resistance heating of a strip material placed in the bond line. The resistance of the tabs is less than that of the strip material. Conducting braid-tubes afford continuous welding when the bond line is curved. Alternatively, an electromagnetic field is used to take advantage of the induction heating. A wide susceptor is used to weld a current conducting substrate while avoiding bulk heating of the substrate. The unexpected property of current-conducting braid-tube susceptors, in which induction heating takes place at the center rather than at the edges of a flattened braid-tube susceptor, is used to obtain long continuous curved welds.
