摘要： A control for varying the speed of advancement of film is described for use in a film projector in which the film is advanced by a shuttle tooth which engages perforations in the film and advances the film along a path between a light source and a projector aperture. The control includes a rotary shutter assembly having one or more shutter blades for interrupting the light from the light source. As the shutter assembly rotates, the shuttle tooth is reciprocated in the direction of film feed by a rotary cam having one or more cam lobes mechanically coupled to the shuttle tooth. The rotation of the cam lobes is synchronized to the rotation of the shutter blades such that the shuttle tooth is positioned for engagement with the perforations associated with the next successive film frame to be projected whenever a shutter blade interrupts the light source. To engage the shuttle tooth with the film perforations, means are included for sensing the interruption of the light source by the shutter blades to generate a train of pulses, each equal in separation to 1/Nth number of light interruptions, (where N is selectable) and, in response to each pulse, means for advancing the shuttle tooth into engagement with the film perforations so that the film may be advanced by the next motion of the shuttle tooth in the direction of film feed. Thus, the film is engaged and advanced upon each reciprocation of the shuttle tooth when N equals one, and at a selectably slower rate when N is greater than one.

摘要： The disclosure relates to a moving target assembly for use in a target practice range. The moving target assembly includes a target, a target travel guide for guiding the target movement and including a pair of straight sections which are substantially at right angles to one another, and a chain drive running substantially parallel to the straight sections. The target includes selectively operable chain engaging devices so that the target may be selectively guided along one straight section or the other. The assembly also includes structure for returning the target to a home position. Also disclosed is a control for controlling a plurality of such assemblies, including selection of the targets, the speed of target travel, the raising and lowering of the targets, and the actuation of the chain drive motors.

摘要： A control system for a cinematographic film cassette processor/projector unit. The control system includes a function programmer comprising an operating cycle selector responsive to a processed/unprocessed indicator on the cassette to program the control system for either a processed-film operating cycle or an unprocessed-film operating cycle and a logic unit for programming the sequence and execution of the plural operational modes of the apparatus during an operating cycle. The control system further includes a reel drive control circuit having plural speed and direction drive control modes programmed by the function programmer, a mode change actuator circiut responsive to cessation of film movement to actuate a change in the operational mode of the processor/projector by changing the logic state of the logic disc assembly, and a manually-actuatable replay circuit.

摘要： A control system for a cassette-load movie camera having an automatic exposure control system. A variable neutral density filter adjusts the exposure control system to the film sensitivity, and a sensitivity range control adjusts the exposure control system alternatively for a range of high film sensitivities or a range of low film sensitivities. Cassette indicia automatically effect a filter setting and sensitivity range setting upon placement of the cassette within the camera. A switching system controls energization of the exposure control system in relation to energization of the camera drive motor.

摘要： The disclosure relates to a fade circuit for a motion picture camera of the type which includes an automatic exposure control. The fade circuit includes a light emitting diode which illuminates the light sensitive device of the automatic exposure control to augment the ambient light levels normally received by the light sensitive device. The intensity of the light emitted by the light emitting diode is controlled by a variable current source which provides the light emitting diode with continuously increasing or decreasing current for increasing or decreasing the intensity of the light from the light emitting diode. Fade-in is obtained as the light intensity of the light emitting diode is gradually decreased from an initial intensity sufficient to close the diaphragm opening to zero intensity to allow the diaphram to assume an opened condition corresponding to ambient light levels. Fade-out is obtained as the light intensity of the light emitting diode is gradually increased from an initial zero intensity which causes the diaphragm to be in an open condition corresponding to ambient light levels to an intensity sufficient to close the diaphragm opening.
摘要翻译： 本公开涉及一种用于包括自动曝光控制的类型的电影摄像机的褪色电路。 褪色电路包括发光二极管，其照亮自动曝光控制的光敏装置，以增加由光敏装置正常接收的环境光水平。 由发光二极管发射的光的强度由可变电流源控制，该可变电流源为发光二极管提供持续增加或减少的电流，以增加或减少来自发光二极管的光的强度。 由于发光二极管的光强度从足以将光阑开口关闭到零强度的初始强度逐渐降低，从而允许光栅呈现对应于环境光水平的打开状态，因此获得淡入淡出。 当发光二极管的光强度从初始零强度逐渐增加时，获得淡出，这使得光阑处于对应于环境光水平的开启状态至足以闭合光阑开口的强度。
