    摘要: APPARATUS IS DESCRIBED FOR TRAINING PERSONNEL IN THE AIMING AND LAUNCHING OF A SHOULDER FIRED ANTI-AIRCRAFT WEAPON. THE APPARATUS COMPRISES A CURVED SCREEN, FILM PROJECTION APPARATUS FOR PROJECTING AN AIRCRAFT IMAGE IN PROPER ATTITUDE THROUGHOUT A TRAJECTORY DETERMINED BY DATA CODED ON THE FILM AND CONVERTED BY DECODING MEANS TO COMMANDS FOR MOVING A PROJECTION BEAM DEFLECTION GIMBALLED MIRROR IN THE PROJECTION APPARATUS. TARGET INFRARED EMMISSION IS SIMULATED BY MEANS FOR

    GENERATING AND MIXING INFRARED ENERGY WITH THE PROJECTION BEAM.

    摘要: A dynamic projection light includes several projection units fixed in a housing and a controller used for sequentially turning on and turning off at least a part of the several projection units to produce at least one moving image. Each projection unit is used for projecting a preset image and includes an LED head, a magnifying lens configured in front of the LED head and configured for diffusing light from the LED head, an optical sheet configured in front of the magnifying lens and having a preset pattern, and a condenser lens configured in front of the optical sheet. By arranging different preset patterns of the optical sheets, utilizing the human visual persistence phenomenon, projected animation images of human or animal walking or running or jumping or swinging, or leaves or petals or snowflakes falling, or objects rolling et al. may be realized, having a strong appreciation.

    摘要: A technique for film marking includes coding a print identifier into a binary-coded serial number; identifying particular frames (bit frames) that will be used to convey the bits (binary digits) of the binary-coded serial number and marking these bit frames in accordance with the particular bit values of the binary-coded serial number. The presence of a predefined mark on a bit frame is representative of a binary digit having a value of one, while the absence of the predefined mark on a bit frame is representative of a binary digit having a value of zero.

    摘要: A motion picture projector for use with magazines containing stacks of cassettes for motion picture film. The housing of the projector supports two coaxial takeup reels one of which assumes a collecting position and collects the film which is being withdrawn from a cassette in a projection position while the other takeup reel assumes a withdrawing position and pays out the film whose presentation is completed and which is being returned to the corresponding cassette. The takeup reels are caused to change positions in response to detection of the trailing portion of the film which is being presented, and such change in positions of the takeup reels take place simultaneously with a stepwise advance of the magazine so as to place a fresh cassette into the projection position while the preceding cassette assumes a position in which a rewinding mechanism rewinds onto its supply reel that film which is stored on the core of the takeup reel occupying the withdrawing position.

    摘要: A copy of a motion picture film is prepared and provided with stop-motion coding in the form of a strip along the sprocket edge which includes emulsion-free segments. To accomplish this, an auxiliary light source is focused on the sprocket edge, and a shutter is moved into and out of blocking position to produce alternate emulsion-free and emulsion-covered segments along that edge. The shutter is operated by a solenoid under control of a relay. When the copy film is reproduced from a master film having stop-motion indicia in the form of successive notches indicating the start and finish respectively of a stop-motion segment, the relay embodies a push-push type of movement and is under the control of a microswitch which senses the notches and pulses the relay at the start and finish.
