    摘要： A high speed motion picture camera wherein the film moves continuously during a filming operation, and having an optical system through which the light passes continuously; hence, the epicyclic camera principle in which the film, the shutter and the image are in coordinated motion. The epicyclic camera may be utilized for taking substantially any number of pictures per revolution with good picture quality and superior picture steadiness.

    摘要： A film transport and control system for a streak camera having a film takeup reel selectively driven by kinetic energy stored in a flywheel which is rapidly accelerated from a standstill to a preselected high angular velocity by a relatively low horsepower electric motor. When building up the flywheel energy, two motorto-flywheel ratios are utilized. At the preselected velocity, the film can be accelerated and maintained at a preselected speed by an electromagnetic clutch between the flywheel and takeup reel. A brake on the supply reel critically dampens the system hen the film reaches approximately 80 percent of the preselected speed.

    摘要： A METHOD AND AN APPARATUS FOR PHOTOGRAPHING RAPIDLY MOVING BODIES, ESPECIALLY PROJECTILES OR THE LIKE, IN WHICH THE RAPIDLY MOVING BODY IS IMAGED ON A MOVING FILM STRIP BY MEANS OF SEVERAL PICTURE-TAKING OPTICAL SYSTEMS WHICH ARE ARRANGED ALONG THE TRAJECTORY OF THE BODY, THE FILM VELOCITY BEING SO CHOSEN THAT THE RATIO OF THE VELOCITY OF THE BODY TO THE VELOCITY OF THE FILM SUBSTANTIALLY CORRESPONDS TO THE OPTICAL IMAGE RATIO OF THE OPTICAL SYSTEMS TO AVOID RELATIVE MOVEMENT BETWEEN IMAGE AND FILM, AND THE OPTICAL SYSTEMS BEING SO ARRANGED AND DIRECTED THAT THE INTERVALS BETWEEN THE POINTS OF THE TRAJECTORY OF THE BODY SIGHTED BY THE INDIVIDUAL OPTICAL SYSTEMS AND THE VELOCITY OF THE PROJECTICLE DETERMINE THE DESIRED PICTURE FREQUENCY.

    摘要： Asynchronous high-speed film transport apparatus wherein supply and take-up reels have opposite ends of an elongated film wound thereupon. A pair of drive motors one for each reel is selectively operable to rotate the reels respectively to move film along a path from one reel to the other. First and second film vacuum chambers are associated respectively with the supply and take-up reels, each chamber being arranged to hold a loop of film, the chambers being positioned adjacent the film path between the reels. Means are connected to the drive motors for producing movement of the film and sensing means are provided for maintaining a predetermined loop of film in each of the chambers during film movement. Between the first vacuum chamber and a read/record station is a first clamp for the film and a storage device for controlling the film advance, the storage device including a movable member for controlling the length of a frame. A second film clamp is positioned opposite the read/record station. Before frame advance, the second film clamp is closed and the first clamp is opened. Film is then pulled from the film loop formed in the supply reel vacuum chamber by applying air pressure and/or vacuum to the film in the storage device. At the same time, the movable member in the storage device, or film advance cavity, is positioned to provide the desired film advance distance. During film advance, the first clamp is closed and the second clamp is opened. Film is then pulled from the film advance cavity into the take-up free film loop by vacuum in the take-up film loop cavity and/or applied pressure.
