    摘要： Pulses are furnished which each indicate transport of a frame. The pulses are counted on a BCD counter. Selected outputs of the counter are connected to the inputs of coupling stages, each including a JK flip-flop. Each flip-flop changes state for a predetermined count on the counter. When each flip-flop changes state, a corresponding indicator lights up, thereby furnishing an indication to the photographer of how many frames have been transported.

    摘要： A motion picture camera wherein the trigger of the camera release is movable from an extended position to a second position in which it starts the camera motor, and beyond the second position to thereby cause an auxiliary tooth to enter a gap in the annulus of teeth at the periphery of a program wheel which forms part of the mechanism for making exposures with dissolve. The auxiliary tooth is thereby moved into the path of cyclical movement of the pallet on a pawl which is driven whenever the motor is on whereby the pallet can move the program wheel from a starting position and thereupon cooperates with the teeth of the program wheel to rotate the latter through one revolution during which the program wheel initiates the making of exposures with fade-out and subsequent rearward transport of film frames which were exposed with fade-out, and prepares the motor for renewed forward transport of such film frames with simultaneous exposure with fade-in. The renewed forward transport is effected by depressing the trigger. The motor remains in operation while the user moves the trigger beyond the second position so that the making of exposures with fade-out can follow, without any interruption, the making of normal exposures.

    摘要翻译： 一种电动摄像机，其中相机释放的触发器可从延伸位置移动到第二位置，在该第二位置，其启动相机电动机，并且超出第二位置，从而使辅助齿进入齿环中的间隙 程序轮的外围，其形成用于溶解曝光的机构的一部分。 辅助齿由此移动到托盘在棘爪上的循环运动的路径，每当马达处于驱动状态时，该爪被驱动，由此托盘可以从起始位置移动程序轮，并且随后与程序轮的齿配合以旋转 后者通过一次旋转，在此期间，程序轮开始进行曝光，随着淡出和随后的向后传输，随着淡出曝光的胶片框架的曝光，并准备电动机再次向前传送这样的胶片框架同时曝光 淡入。 更新的正向运输是通过抑制触发来实现的。 当用户将触发器移动到第二位置之后，电动机保持运行，使得可以随时进行具有淡出的曝光，而不会中断正常曝光。

    摘要： A motion picture camera with variable focal length lens wherein the zooming collar and the distance selecting or focusing collar on the lens barrel are rotatable to neutral positions by an actuating member which is movable at right angles to or in parallelism with the optical axis of the lens. In such neutral positions of the collars, the focal length of the lens is satisfactory for the making of exposures in daylight or artificial light, and the distance setting corresponds to a distance of 4 to 6 meters to thus guarantee an acceptable depth of field for exposures of subjects located anywhere between closeup and infinity. The actuating member can further close a master switch to allow for starting of the camera motor in immediate response to depression of the release trigger.

    摘要： A film advancing arrangement for a film projector having an optical system and two spools between which a film is advanced, comprises two spool supports for carrying a supply spool and a takeup spool respectively. The spool supports are pivotally mounted with respect to the housing of the projector to be positioned inside of the housing or outside of the housing so that the spools of small standard diameters may be located within the contours of the housing and the spools of large standard diameters may be mounted on the same spool supports and located outside of the housing.
