US Patent:

45585857, Dec 17, 1985

Filed:

Mar 19, 1984

Appl. No.:

6/590921

Inventors:

Robert F. Berry - Hayes VA

Assignee:

The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC

International Classification:

G01N 2904
G01D 1800

US Classification:

73 1DV

Abstract:

This invention is a method for providing an impression profile in a reference standard material utilized in inspecting critically stressed components with pulsed ultrasound. A die stamp (10) having an I letter, reference numeral (36), is used to impress a reference material (50) having a surface (52). The die stamp is placed against the surface (52) and struck with an inertia imparting member to impress the I in the reference standard material. Upset (54) may appear on the surface (52) as a result of the impression and is removed to form a smooth surface (52). The stamping and upset removal is repeated until the entire surface area of a depth control platform (30) on the die stamp uniformly contacts the material surface (52). The I impression profile in the reference standard material (50) is utilized for reflecting pulsed ultrasonic beams as a means for inspecting ultrasonically.

Appl. No.:

7/151863

Inventors:

Robert F. Berry - Hayes VA

International Classification:

G02B 2326
G01B 1102

US Classification:

356241

Abstract:

The invention is an adapter tip 11 for supporting measuring indicia 22 on the forward end 12 of a conventional optical borescope 14 including focus adjustment means thereby permitting the substantially direct, physical measurement of internal surfaces and defects inside an object such as a pressure vehicle having an external opening therein when said measuring indicia 22 are positioned to coincide with a surface orb defect to be measured and simultaneously brought into focus with said surface or defect with said focus adjustment means.

International Classification:

G01B 1506

US Classification:

378 58

Abstract:

The invention is a method of radiographic inspection of a wooden specimen 11 for internal defects which includes the steps of introducing a radiopaque penetrant into any internal defects in said specimen 11 through surface openings therein; passing a beam of radiation through a portion of the specimen to be inspected; and making a radiographic film image of the radiation passing through said specimen, the radiopaque penetrant in said specimen absorbing a portion of said radiation passing therethrough, thereby enhancing the resulting image of said internal defects in said specimen 11.

International Classification:

F16F 15/00
F16F 15/023
G01M 7/02

Abstract:

A tuned mass system has a bulk mass acted upon by an excitation amplitude and a reaction mass coupled to the bulk mass. A resistance-to-motion controlled coupling mechanism associated with the reaction mass is configured to proportionally modulate independent of excitation force such that the relative phase of the bulk mass and the reaction mass is substantially constant throughout an extended range of excitation amplitude. The resistance-to-motion controlled coupling mechanism is a Variable Aperture Reciprocating Reed (VARR) Valve in one embodiment, and operates as a passive mechanism. In other embodiments, active resistance-to-motion controlled coupling mechanisms are employed.
