US Patent:

43777368, Mar 22, 1983

Filed:

Aug 14, 1981

Appl. No.:

6/292856

Inventors:

John E. Daunt - Albuquerque NM
John P. Tipton - Albuquerque NM
John E. Adair - Albuquerque NM

Assignee:

General Electric Company - Cincinnati OH

International Classification:

B23K 2700

US Classification:

219121LH

Abstract:

The relative position of a plurality of holes through a surface of a member, the holes having been generated by high energy means, such as a laser, which vaporizes material of the member to produce a light flash, is inspected and controlled as the holes are being generated using a light sensing means which is responsive to the light flash and which observes the relative positions of the holes being produced. The light sensing means signals a hole pattern comparison means which compares the actual hole pattern with a preselected hole pattern. Adjustment can then be made to reposition the high energy beam if required to correct undesirable error in the actual hole pattern during generation of the holes.

International Classification:

B32B 3500

US Classification:

156285

Abstract:

A plurality of cooperating members of an article are heat bonded at interface surfaces through use of a bonding material at such surfaces and fluid pressure, such as through a resilient, single- or multi-compartment closed member, applied through a flexible heating blanket. Heat is applied at least partially through the heating blanket and preferably through the blanket and through a backing member, such as a mold, which carries heating means.
