US Patent:

41059298, Aug 8, 1978

Filed:

Jun 30, 1976

Appl. No.:

5/701381

Inventors:

Robert J. Cosco - Amesbury MA

Assignee:

GTE Sylvania Incorporated - Danvers MA

International Classification:

H05B 4130
H02H 720

US Classification:

315125

Abstract:

A flashtube has an hermetically sealed glass envelope containing an inert gas and a pair of electrodes between which an arc discharge path is defined during lamp operation, and an insulated external trigger wire at the outer surface of the envelope. The trigger circuit includes a safety feature in the form of a sealed spaced gap to prevent an arc from occurring in the flashtube in the event that the flashtube envelope is cracked or broken.

Assignee:

GTE Sylvania Incorporated - Stamford CT

International Classification:

G03B 1502

US Classification:

362 16

Abstract:

A flash assembly which uses an elongated arc discharge flash tube positioned within a reflector. A trigger bar member fits within a slot of the reflector and is located adjacent the tube. The reflector, trigger bar, and the contacts which electrically connect the electrodes projecting from the tube to a suitable power source are mounted within an insulative base. The invention is particularly suited for use within a camera assembly.

Assignee:

GTE Sylvania Incorporated - Stamford CT

International Classification:

H05B 4134

US Classification:

315241R

Abstract:

A multiflash system including an arc discharge flashlamp having an elongated tubular envelope and containing three electrodes. A direct current voltage source comprising a large storage bank with positive and negative terminals is connected across two of the electrodes, and a storage capacitor is connected between the third electrode and the negative terminal of the source. The capacitor-connected electrode defines a first arc path with the electrode connected to the positive terminal of the source and a second arc path with the electrode connected to the negative terminal of the source. Trigger pulses are applied to the lamp so as to alternately energize the first and second arc paths, the storage capacitor being charged when the first arc path is energized to flash and discharged when the second arc path is energized to flash.

International Classification:

H01J 6112

US Classification:

313185

Abstract:

A UV source comprising an arc lamp containing deuterium gas at an initial fill pressure in excess of that at which peak UV light intensity occurs, thereby extending the useful life of the lamp.

International Classification:

H01J 6500

US Classification:

313185

Abstract:

A xenon flashtube having an envelope formed of soft glass tubing with a pair of electrodes disposed at each end of the envelope for providing a wall-stabilized discharge. The use of soft glass permits a match seal to dumet lead-in wires and results in a lower cost unit.

Assignee:

GTE Sylvania Incorporated - Danvers MA

International Classification:

H01J 6104

US Classification:

313178

Abstract:

A cold cathode arc discharge flash lamp has a cathode assembly in which an electron emissive pellet is secured on the lead wire or rod entering the flash tube envelope. One or more coils of molybdenum or a similar body of ceramic refractory shield the emissive face of the pellet from destructive ion bombardment while exposing the face for electron emission.

H01J 6154

US Classification:

313198

Abstract:

A high voltage xenon filled flash tube has a trigger conductor wire embedded in the glass envelope of the tube or in an aluminum reflector on the tube. The wire does not penetrate the glass envelope nor enter the gas filled volume through which arc discharge occurs.

H05B 4130

US Classification:

315335

Abstract:

A flash tube having an elongated tubular envelope containing a pair of anode electrodes disposed at opposite ends and a centrally located cathode electrode which is common to both anodes for simultaneously defining two separate arc discharge paths during operation. The three-electrode configuration is particularly useful in photograhic and photocopying applications for minimizing dark spots and providing a shorter flash duration.
