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.

Raytheon Company - Lexington MA

International Classification:

H01Q 1310

US Classification:

343771

Abstract:

An improved slot array antenna with a circular aperture and linear polarization is shown to be made up of a plurality of slotted waveguides having different lengths and different widths. The slots in the waveguides are positioned to optimize amplitude taper in any plane passing through the center of the array normal to the surface thereof and to maximize the number of such slots.

Thomas B. Dowling - Lowell MA

Assignee:

Raytheon Company - Lexington MA

International Classification:

H01Q 138

US Classification:

343700MS

Abstract:

An antenna, adapted to be used as a monopulse antenna in a guided missile, is shown to comprise four separate microstrip circuits in different quadrants of a circular microstrip arrangement, each one of such microstrip circuits being made up of an array of contiguous rectangular meshes with the widths of the shorter sides of such meshes being varied to provide an amplitude taper.
