Filed:

Sep 11, 2001

Appl. No.:

09/950503

Inventors:

Richard F. Conti - Philadelphia PA
William McCauley - Wynnewood PA
Gregory Kopansky - Philadelphia PA

Assignee:

Heraeus Electro-Nite Co. - Philadelphia PA

International Classification:

G01N 2700

US Classification:

324 714

Abstract:

A probe for measuring particulates in molten metal includes an inner metal receiving chamber, with an orifice to permit metal to flow into the chamber. A first electrode extends into the chamber and a second electrode surrounds at least a portion of the chamber. The electrodes are connected to a measurement device for measuring changes in the electrical potential produced by the passage of particulates entrained in the molten metal passing through the orifice. An outer sheath of heat resistant material surrounds the second electrode and a gas passageway extends out of the inner tube for creating a pressure differential within the chamber for facilitating the flow of molten metal through the orifice. A liquidus depressing material is in the chamber to lower the liquidus temperature of the molten metal and permit a longer time period for detecting and measuring particulates in the molten metal.

Appl. No.:

7/461493

Edwin Kaufman - Ambler PA

Assignee:

ElectroNite International, N.V. - Antwerp

International Classification:

C21B 724

US Classification:

75377

Abstract:

A method and apparatus for introducing an additive material into a metallurgical sample. In a preferred embodiment, the method and apparatus of the present invention comprises introducing a stabilizer, for example, tellurium and/or bismuth, into a metallurgical sample of cast iron or blast furnace hot metal to induce white solidification comprising a probe having a generally enclosed sample cavity and a conduit extending from the cavity for receiving a flow of molten metal for collection in the cavity. A distribution member proximate the conduit is employed for inserting a predetermined quantity of the additive material at a predetermined rate into the molten metal flowing through the conduit so that the additive material is homogeneously distributed throughout the molten metal within the sample cavity.

Appl. No.:

7/273614

Inventors:

Richard Conti - Holland PA

Assignee:

Electro-Nite Company - Philadelphia PA

International Classification:

G01N 2504
G01K 114

US Classification:

374139

Abstract:

A device for measuring both the phase change temperature of a sample of a molten metal bath and the actual bath temperature by means of a single thermocouple. The device having a chamber defined by a housing such that the housing will be consumed by the molten metal bath after determination of the phase change temperature of the sample within the chamber. After consumption of the housing, the sample remelts into the bath and the thermocouple determines the bath temperature.

International Classification:

B23K 2010

US Classification:

174 94R

Abstract:

An improved method of ultrasonically welding together two conductors having differing lateral dimensions comprising selecting a welding capture fixture having lateral sides spaced apart by a distance substantially equal to the lateral dimension of a first conductor having the greatest lateral dimension. The first conductor is placed in the selected fixture so that the first conductor is proximate to or substantially engages both lateral sides of the fixture. The second conductor is formed so that at least a first portion extends laterally beyond a second portion. The second conductor is placed into the select fixture so that the first portion is proximate to or substantially engages one of the lateral sides of the fixture and the second portion is proximate to or substantially engages the other lateral side of the fixture with both portions substantially engaging the first conductor. Ultrasonic energy is applied to one of the conductors within the fixture for moving the one conductor with respect to the other conductor for welding the conductors together. In a preferred embodiment, one of the conductors is an electrical lead of a sensing element and the other conductor is a multi-stranded extension wire.
