Abstract: A motion picture camera wherein a rotary shutter is movable between first and second angular positions in which its blade respectively overlies and is out of register with the lightadmitting aperture. An adjustable first pulse generator is provided to effect movements of the shutter from the first to the second position at preselected intervals to thereby start exposure with long exposure times. A second pulse generator is activated when the shutter assumes its second position and effects a movement of the shutter back to the first position with a delay which is a function of scene brightness but is invariably shorter than a preselected interval. The two pulse generators control a two-way switch which can cause an electromagnet to disengage an intercepting lever from the shutter whereby the lever starts the motor which rotates the shutter from the first to the second position when the switch is actuated by the first pulse generator and from the second to the first position when the switch is actuated by the second pulse generator.

Abstract: A shutter control system for controlling the exposure of film in a motion picture camera. The system includes shock absorbing apparatus for stopping the shutter in a selected position with minimum impact forces, and apparatus to drive the shutter to the selected position regardless of the point in the operating cycle at which the system is stopped by the camera user. The system further includes an over-center spring to eliminate camera chatter by positively locating the system components in either a run or a stopped position.

Abstract: The shutter of a still camera is normally held in a closed and cocked position by a lever which is biased by a torsion spring to bear against a pivotable impeller. The latter can be cocked by the film transporting mechanism and is normally held in the cocked position by the camera release member. When the release member permits the impeller to move to its uncocked position, the latter strikes against the pin of a piezoelectric device to thereby fire a flash lamp or an electronic flash for artificial illumination of the subject. The lever is provided with an adjustable cam which is located in the path of movement of the impeller to its uncocked position so that the impeller engages the cam and disengages the lever from the shutter. The shutter opens a preselected interval of time ahead of the generation of artificial light, and the length of such interval is determined by the distance between the uncocked position of the impeller and that intermediate position in which the impeller engages the cam to disengage the lever from the shutter.
Abstract translation: 静止照相机的快门通常由杠杆保持在闭合的位置，该杠杆被扭转弹簧偏压以抵靠可枢转的叶轮。 后者可以通过胶片传送机构来锁定，并且通常由照相机释放构件保持在被启动的位置。 当释放构件允许叶轮移动到其未锁定位置时，该叶片撞击压电装置的销，从而发射闪光灯或电子闪光灯，以对被摄体进行人造照明。 杠杆设置有可调节的凸轮，其位于叶轮运动到其未锁定位置的路径中，使得叶轮接合凸轮并使杠杆与快门分离。 快门在人造光产生之前打开预选的时间间隔，并且这种间隔的长度由叶轮的未锁定位置与叶轮接合凸轮的中间位置之间的距离确定，以使杆脱离 快门。

Abstract: A cyclically operable, optical shutter particularly suited for use as a focal plane shutter, characterized by an occulting disk having a pair of radiation occulting sectors defining therebetween a pair of diametrically opposed, radiation transmitting sectors driven in rotation by a D.C. motor. A particular feature of the shutter resides in a combination of a servo-control system with the motor for accelerating the disk from a steady state of zero velocity to a preselected steady state of angular velocity, maintaining the steady state during a predetermined period of radiation transmission, and subsequently decelerating the disk to a steady state of zero velocity within a fraction of a single revolution, whereby a pulse of radiation having a preselected width is gated through an associated aperture with a high degree of uniformity and reproducibility.

Abstract: Shutter mechanism for a photographic camera in which a shutter blade is opened by a spring loaded impact driver controlled by a shutter release lever. When the blade is driven open it strikes a resilient stop which absorbs the impact energy of the shutter blade and returns the shutter blade softly for engagement by a latch device. The impact energy imparted by the blade to the resilient stop can be employed for various functions, such as the actuation of a switch in an electronic timing circuit that controls shutter speed.

Abstract: A braking device for shutter blades or the like which comprises a pivotable actuating member normally extending into the path of movement of the blade and serving to displace a braking member which is thereby urged against the blade, preferably in a direction at right angles to the direction of movement of the blade, to produce a controlled braking action. The braking member is integral with or is coupled to the actuating member by a torsion spring or the like. Elastic cushions are provided on the actuating and braking members in such positions that the cushion of the actuating member is struck by the moving blade and the cushion of the braking member strikes against the blade in response to resulting displacement of the actuating member.

Abstract: A photographic camera shutter arrangement includes first and second magnetic windings which respectively control the opening and closing movements of the shutter blades. The windings are pulse-energized, the interval between the energization of the first winding by a first control pulse and of the second winding by a second control pulse determining the exposure time of the shutter. A braking pulse applied after a control pulse is applied to a winding other than that to which the control pulse is applied retards movement of the shutter blades in the direction dictated by the control pulse so that ''''bouncing'''' or rebounding of the shutter blades is reduced.
