摘要： IN A PHOTOFLASH SYSTEM, MEANS ARE PROVIDED FOR CONTROLLING THE EFFECTIVE LIGHT OUTPUT FROM A FLASH BULB IN ACCORDANCE WITH DEMAND. THE MEANS INCLUDE LIGHT SENSING MEANS RESPONSIVE TO LIGHT REFLECTED FROM THE OBJECT OF THE PHOTO. SIGNALS FROM THE SENSING MEANS ARE INTEGRATED AND USED TO TRIGGER MEANS FOR OBFUSCATING THE LIGHT SOURCE. THE LATTER MEANS MAY INCLUDE A VAPORIZABLE SUBSTANCE, A DEFLAGRATING SUBSTANCE OR THE LIKE WHICH, IN RESPONSE TO THE TRIGGER SIGNAL, FORMS AN OPAQUE SHIELD BETWEEN THE LIGHT SOURCE AND THE PHOTOGRAPHIC OBJECT.

摘要： Disclosed herein is a strobe flash apparatus with a modular construction in which the gas-filled flash tube and the circuit components are mounted on a printed circuit board to form a circuit module. The circuit module is mounted in a tubular housing with the camera sync-plug interfitting in a through aperture in the housing wall to anchor the circuit module against axial and angular displacement. The flash tube plugs into a socket at one end of the module and is located within a transparent protective cover to afford 360* light emanation. The circuit includes a light sensitive silicon controlled rectifier located in registry with a window in the housing to afford use of the flash as a light triggered slave unit. An axially shiftable sleeve on the housing is positionable over the window when the flash is triggered with the camera shutter contacts. A neon ready light is located in the transparent cover adjacent the flash tube and blinks or pulsates to indicate that the power pack has recycled and is ready for firing. A high resistance bridge minimizes idling drain of the battery in the power supply, and a high resistance and low current in the semi-conductor isolated trigger circuit minimizes burn of shutter contacts.
摘要翻译：本文公开了一种具有模块化结构的闪光闪光装置，其中充气闪光管和电路部件安装在印刷电路板上以形成电路模块。电路模块安装在管状外壳中，相机同步插头相互配合在壳体壁上的通孔中，以使电路模块抵抗轴向和角位移。闪光管插入模块一端的插座，位于透明保护罩内，可提供360度光散射。该电路包括光敏硅控整流器，其位于与壳体中的窗口对准的位置，以便将闪光灯用作光触发的从单元。当闪光灯被相机快门触点触发时，壳体上的可轴向移动的套筒可定位在窗口上方。霓虹灯就位于与闪光管相邻的透明盖中，并闪烁或脉动，以指示电源组件已循环使用，并准备就绪。高电阻桥可以最大限度地减少电源中的电池的空载消耗，并且半导体隔离触发电路中的高电阻和低电流可最大限度地减少快门触点的烧伤。

摘要： A percussive-type photoflash lamp, the primer of which comprises a wire anvil partially coated with fulminating material and coaxially supported within a tube in a manner providing a clearance between the coating of fulminating material and the inner wall of the tube. The fulminating material includes a red phosphorus fuel, a chlorate salt oxidizer, a powder combustible, incandescible metal, and a powdered carbon additive for facilitating propulsion of the powdered metal from the primer tube into the lamp envelope when ignited. The fulminating material is prepared and applied in the following manner: the red phosphorus, powdered metal and powdered carbon area dispersed in water to provide an aqueous slurry; the anvil wire is dipped into this aqueous slurry; the coating is dried; a dissolved chlorate salt solution is prepared; and the coated wire is dipped into the chlorate solution so as to permeate the previously applied coating.

摘要： A PHOTOFLASH UNIT HAVING PERCUSSION-IGNITABLE FLASH LAMPS AND INDIVIDUAL, PREENERGIZED STRIKERS IS PROVIDED WITH DISARMING LATCH MEMBERS FOR EACH STRIKER WHICH PREVENT ACCIDENTAL RELEASE OF THE STRIKERS. THE DISARMING MEMBERS HAVE CAM PORTIONS ASSOCIABLE WITH PHOTOGRAPHIC APPARATUS FOR MOVING THE LATCH MEMBERS TO AN INOPERATIVE POSITION UPON MOUNTING OF THE FLASH UNIT ON THE APPARATUS. APPARATUS IS DISCLOSED FOR COOPERTING DURING MOUNTING OF SUCH UNITS TO ARM THE UNIT FOR SELECTIVE RELEASE OF THE STRIKERS. THE DISARMING MEMBERS ARE RESILIENTLY URGED TO THEIR OPERATIVE POSITION SO THAT UNRELEASED STRIKER ELEMENTS ARE AGAIN DISARMED UPON REMOVAL OF THE FLASH UNIT FROM PHOTOGRAPHIC APPARATUS.
