The switch devices are prepared in a conventional manner from a particulate mixture of silver oxide with a metal exhibiting both thermal and electrical conductivity but which does not react exothermally with said silver oxide. A binder mixture is used which includes a conventional organic polymer binder which serves as a fuel during conversion of the silver oxide together with a second organic polymer binder which is more resistant to combustion.Type: GrantFiled: December 20, 1982Date of Patent: December 11, 1984Assignee: General Electric CompanyInventors: Mary S. Jaffe, Vaughn C. Sterling

Patent number: 4424020Abstract: An electrically-activated, miniature photoflash unit which includes a plurality (e.g., ten) of subminiature high voltage flash lamps arranged in a planar array. A singular mounting tab protrudes from the unit's housing and serves to connect the entire array when the tab is electrically connected to a power source (e.g., piezoelectric crystal) typically associated with many of today's cameras. Each of the lamps is inverted with respect to the tab and also serve to provide a low resistance circuit path therethrough subsequent to activation thereof.Type: GrantFiled: May 8, 1981Date of Patent: January 3, 1984Assignee: GTE Products CorporationInventors: Andre C. Bouchard, George J. English, Harold H. Hall, Jr., John A. Scholz

Patent number: 4379690Abstract: A sequentially operable multilamp photoflash array includes a plurality of radiation-responsive normally open (N/O) connect type switches which are prepared from a composition which includes a filler material, a binder, silver coated particulate solids and silver-salt coated particulate solids. The switches are fabricated by a process wherein the silver coated particulate solids are stirred in potassium permanganate, added to an admixture of silver coated glass beads, a filler material and an organic binder and deposited onto a printed circuit board.Type: GrantFiled: August 13, 1981Date of Patent: April 12, 1983Assignee: GTE Products CorporationInventors: Michael R. Kling, Carl F. Kackenmeister

Patent number: 4336570Abstract: A photoflash unit having a plurality of flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps in response to successive firing pulses applied thereto. The circuitry includes a plurality of solid-state switches capable of being activated by radiant energy generated during flashing of lamps located adjacent to respective switches. Initially, each of the switches has a resistance sufficiently high to provide an open circuit to the applied firing pulses, and after being activated by radiation, the switch undergoes chemical conversion to a conductive state over a finite time interval. The switches are prepared from compositions comprising admixtures of silver carbonate and/or silver oxide, silver-coated glass beads and a binder; the admixtures may also include electrically non-conductive particulate solids, such as titanium dioxide, and/or silver-coated metal beads.Type: GrantFiled: May 9, 1980Date of Patent: June 22, 1982Assignee: GTE Products CorporationInventors: Boyd G. Brower, Gary L. Houseknecht

Patent number: 4334856Abstract: A photoflash lamp array having a plurality of 2n flashlamps, a common terminal connected to one lead-in wire of each of the lamps, and a plurality of n selective terminal means, each associated with a respective pair of the lamps and directly connected to the non-common lead-in wire of one lamp of each pair. A respective normally open switch is coupled between the non-common lead-in wires of each of the pairs of lamps associated with a selective terminal. Each of the switches is responsive to the flashing of the directly connected lamp of an associated pair so as to electrically connect the other lamp of the pair to the associated selective terminal. In one specific example, ten lamps are selectively paired to be operated sequentially by firing pulses successively applied to five selective terminals together with a common terminal.Type: GrantFiled: June 6, 1980Date of Patent: June 15, 1982Assignee: GTE Products CorporationInventors: David R. Broadt, Emery G. Audesse
