US Patent:

41621522, Jul 24, 1979

Filed:

Sep 9, 1977

Appl. No.:

5/831723

Inventors:

James Petro - Little Falls NJ

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

C03B 526

US Classification:

65164

Abstract:

A molten glass metering device for making electric lamp bases by accurately metering the rate of flow of molten glass from an orifice in the wall of a glass melting furnace. The device comprises a metal member including an integral hollow elongated member aligned with the orifice. The flow of glass is controlled by varying the flow of electrical current through the metal member to control the temperature of same and to control the temperature of the glass within the metal member, thereby to control the rate of flow of molten glass therethrough.

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

B21C 900

US Classification:

72286

Abstract:

A system for heating wire during a wire drawing process which comprises one or more cylindrical silicon carbide tubes each having an aperture in the side wall thereof. A flame projecting burner is situated adjacent the aperture in the side wall of each tube for projecting a flame through the aperture onto a wire passing through the cylindrical tube. The arrangement causes the wire to be heated by direct impingement of the flame onto the wire, residual flame and hot gases redirected by the cylindrical tube longitudinally of the wire and radiant heat from the cylindrical silicon carbide tube.

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

B65H 5116

US Classification:

221 1

Abstract:

A method and apparatus for supplying filament coils to a mount machine which includes a pair of vibratory storage bowls each having a filament coil discharge location which alternately feed filament coils on demand from the mount machine. There is further included sensing devices and logic circuitry which cause a filament coil to be fed from the other of the filament coil discharge locations when a filament coil is not present at the selected filament coil discharge location.
