  • Patent number: 5892992
    Abstract: A photoflash unit includes a housing with an internal chamber containing a charge material. The housing's base has an opening. A primer is placed over or proximate to this opening. An anvil is placed over the material and a burn-away sheet is placed over the anvil. The burn-away sheet is sealed to the base and holds the anvil in place. When the anvil is struck percussively through the burn-away sheet, the primer ignites combustible material through the opening in the back wall. The burn-away sheet burns away, allowing the photoflash unit to vent to the rear.

  • Patent number: 5871345
    Abstract: A compact flash lamp array includes a housing defining a plurality of cavities. Each cavity has a light emitting opening and a primer vent opposite the light emitting opening. A combustible mass is deposited in each cavity over the primer vent and a primer mass is deposited on the outside of the housing over each primer vent. A primer is cover secured over each primer mass, and a sheet of transparent material is bonded over the cavities in the housing.

  • Patent number: 5871346
    Abstract: A compact flash lamp array includes a housing defining a plurality of cavities, each cavity having a light emitting opening and an exhaust vent and containing a combustible mass. A transparent cover is fixed over the light emitting opening and means are provided for individually firing the combustible mass in each cavity. A valve cooperating with the exhaust vents opens the exhaust vent of a cavity in which a combustible mass is fired and closes the cavities containing unfired combustible masses.

  • Patent number: 5871344
    Abstract: A compact flash lamp array includes a housing defining a plurality of cavities, with each cavity having a light emitting opening and a combustible mass deposited in each cavity. A firing means such as an electrically heated filament or percussive primer is provided for individually firing the combustible mass in each cavity. Each cavity in the housing is provided with a porous portion communicating to the outside of the cavity having sufficient porosity to maintain cavity integrity during combustion of the combustible mass contained in a cavity while retaining combustion by-products.

  • Patent number: 5761551
    Abstract: A camera comprising a main body part having a film chamber, and a multi-lamp flash wheel supported for rotation to move successive flash lamps from a storage to a use position for illuminating a subject to be photographed. The multi-lamp flash wheel is rotatable about the film chamber to make the camera relatively compact.

  • Patent number: 5752104
    Abstract: A camera is intended to be used with a multi-lamp flash wheel having flash lamps that are tilted from storage orientations to ignition orientations as the respective lamps are moved to behind a flash emission window. Tilting the flash lamp to its ignition orientation cocks a striker finger, which when released triggers flash ignition.

  • Patent number: 5697003
    Abstract: A camera comprising a light sensitive film on which a certain number of exposures can be made, and a multi-lamp flash source having a plurality of one-time-use flash lamps equal in number to the total number of exposures to be made on the film, is characterized in that the multi-lamp flash source has consecutive indicators proximate the respective lamps for indicating the number of exposures available to be made and is supported for movement to move the respective lamps from a storage to a use position for illuminating a subject to be photographed and, substantially simultaneously, to move the respective indicators from a concealed to a visible position.

  • Patent number: 5649242
    Abstract: In a camera, a circular array of flash lamps is arranged radially with respective ignition ends of the lamps closer to one another than respective opposite ends of the lamps. Each one of the lamps has respective ignition stems projecting from the ignition ends of the lamps to be struck to ignite the lamps. A one-piece reflector ring is located behind the circular array of lamps with respective disk portions of the reflector disk extending radially over each one of the lamps between the ignitions ends and opposite ends of the lamps to reflect flash illumination from the lamps non-radially. A one-piece striker ring is located behind the reflector ring and has respective striker fingers extending radially over the lamps for striking the ignition stems of the lamps. The circular array of flash lamps, the reflector disk and the striker ring are supported for simultaneous rotation to position respective trios of the lamps, the disk portions and the striker fingers successively behind a flash emission window.
