US Patent:

50842293, Jan 28, 1992

Filed:

May 31, 1990

Appl. No.:

7/531355

Inventors:

Robert E. Welsh - West Mifflin PA
Marvin J. Doman - McKeesport PA
Edward C. Wilson - West Mifflin PA

Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC

International Classification:

G21C 1700

US Classification:

376257

Abstract:

An apparatus for testing, in situ, highly irradiated specimens at high temperature transients is provided. A specimen, which has a thermocouple device attached thereto, is manipulated into test position in a sealed quartz heating tube by a robot. An induction coil around a heating portion of the tube is powered by a radio frequency generator to heat the specimen. Sensors are connected to monitor the temperatures of the specimen and the induction coil. A quench chamber is located below the heating portion to permit rapid cooling of the specimen which is moved into this quench chamber once it is heated to a critical temperature. A vacuum pump is connected to the apparatus to collect any released fission gases which are analyzed at a remote location.

Filed:

Mar 14, 1986

Appl. No.:

6/839782

Inventors:

Robert E. Welsh - Mount Lebanon PA

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

G01N 328

US Classification:

73 87

Abstract:

Apparatus and method for determining the fracture resistance of thin wall hollow articles when ironed, the method including the step of providing a drawing die and punch or a mandrel having a portion thereof tapered in a continuous, linear manner. The taper is such that it provides a continuous decrease in punch-to-die clearance when the two are moved together, and thus a continuous range of ironing reductions along the side wall of an article located between the punch and die. The taper of the punch begins adjacent the forward end thereof and is sized to effect conventional thinning of the side wall of the article at the onset of ironing. The final diameter of the taper of the punch, however, is such that fracturing of the side wall is assured in the ironing process.

International Classification:

B07C 5342

US Classification:

209 75

Abstract:

A secondary light sensitive photoelectric product separator for use with a primary product separator that concentrates a material so that it is visually distinguishable from adjacent materials. The concentrate separation is accomplished first by feeding the material onto a vibratory inclined surface with a liquid flow, such as a wet concentrating table. Vibrations generally perpendicular to the stream direction of flow cause the concentrate to separate from its mixture according to its color. When the concentrate and its surrounding stream reach the recovery end of the table, a detecting device notes the line of color demarcation and triggers a signal if it differs from a normal condition. If no difference is noted nothing moves on the second separator. However, if a difference is detected in the constant monitoring of the color line's location, a product splitter and recovery unit normally positioned near the color line at the recovery end, moves to a new position.

Filed:

May 12, 1987

Appl. No.:

7/048832

Inventors:

Robert E. Welsh - Pittsburgh PA

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

B21D 2221

US Classification:

72347

Abstract:

A method and apparatus for measuring the sidewall tension in a workpiece being drawn through a draw die and/or ironing die. A punch is provided which is adapted to measure and continuously monitor the axial load on the punch nose and the total axial load on the punch, the distribution of such loads around the periphery of the punch, and bending of the punch near the base and nose due to lateral and nonuniform forces acting on the punch as the workpiece is forced through a die or dies. Determination of the forces, their distribution, and punch bending enables accurately determining the tensile stress at any portion of the sidewall.

International Classification:

US Classification:

72 45

Abstract:

The invention includes apparatus and method for lubricating and cooling a workpiece, dies or ironing rings, and punch at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article. A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers. After applicaiton, the lubricant and coolant are separated, the lubricant filtered to remove debris, stored, and then reinjected to provide lubrication for the process.
