Abstract: A flat rolled metal product (1) is first hot-rolled in at least one rolling stand (2), then fed to a cooling zone (5) arranged downstream of the rolling stand (2) and finally cooled in the cooling zone (5). During the rolling in the rolling stand (2), the flat rolled product (1) is oriented horizontally. Before running into the cooling zone (5) and/or when running into the cooling zone (5), the flat rolled product (1) is turned by a first acute angle (a) about an axis running in the transporting direction (x), so that after completion of the turning about the axis the flat rolled product (1) is oriented obliquely. The flat rolled product (1) is cooled in the cooling zone (5) while it is oriented obliquely. The product (1) is then returned to horizontal orientation.

Abstract: A portable, trapping system for capturing and non-lethally retaining a large number of large animals, such as wild horses or feral hogs. A specialized trailer aligns and secures deployable corral components for transportation. The corral comprises a modular fence erected on-site from multiple fence panels that are hinged together by pinning. The fence panels are configured with voids to prevent animal climbing. A gate with a remotely actuated trap door is similarly pinned between adjacent fence panels. The gate threshold is concealable. Stakes secure panels to the ground, forming a stable enclosure. The trailer comprises a rigid, confining frame structure adapted to constrain and transport corral components. When the corral is disassembled, multiple individual fence panels to be moved are slidably captivated between channels on first and second confining surfaces, being maintained in a parallel and stable configuration during transportation.

Abstract: Electronically controlled film transport methods and systems are described. One system described comprises a film transport path for transporting film, an input drive assembly for advancing film through the film transport path, an output drive assembly for advancing film out of the film transport path, an aperture positioned in the film transport path, at least one registration pin capable of engaging at least one perforation in the film to secure a portion of the film in the aperture, wherein the at least one registration pin is capable of retracting to a non-engaging position, and a controller for controlling the retraction of the at least one registration pin.

Abstract: A stable, continuous, high-speed roll film media path is established between supply and take-up film reels. Supply and take-up path segments isolate a core transport path section from significant non-linear forces, thereby enabling continuous, high-speed, high-accuracy scan line imaging of the media. The supply and take-up path segments each operate to continuously maintain open decoupling loops in the film media while accurately controlling the speed, tension and alignment of the film media as transported through the core transport path section. A microcontroller operates two motor driven capstans to establish the film media speed and tension within the core transport path section. Optical sensors provide feedback to the microcontroller in managing two additional motor driven capstans to maintain the decoupling loops. The film media within the core transport path section is thereby isolated from frictive, inertial, and skewing forces that could otherwise degrade the media imaging.

Abstract: A loop region in which a loop of a negative film is formed is provided between a pre-scan section and a fine scan section. When a frame image recorded on the negative film is read, a control circuit effects control such that respective processings in the pre-scan section and the fine scan section are performed concurrently in a state in which a length of the loop in the loop region is within a predetermined allowable range.

Abstract: The invention is a mechanism for mounting a film shutter and assembly to a conveyor in a motion film projector, the film shutter assembly including a shutter secured to a mounting bracket, which houses a pair of trucks. Preferably, the mounting bracket securely houses a first truck and slidably houses a second truck to accommodate for the trucks passing over straight and curved portions of the truck, or shutter path. The trucks are rigidly clamped to the conveyor. This configuration permits the shutter to be stably coupled to the conveyor while permitting the shutter assembly to travel along both straight and curved paths. The trucks are generally configured to ride in a raceway, which supports the trucks and maintains the trucks on a predetermined truck path. In one embodiment, the trucks include rollers, which roll along an elongated channel formed in the raceway. According to another embodiment, the trucks include air bearings for carrying the truck along a pressurized raceway.

Abstract: A system and method are disclosed for transporting film in a motion film projector. The system includes a set of film carriages and a set of secondary shutters mounted on a conveyor, which continually advances the film carriages and the secondary shutters along a linear path oriented orthogonally with respect to an optical axis of a aperture block, through which images on the film are projected. Each film carriage receives a loop of film and then rolls the loop of film in the direction of the aperture block. A deceleration mechanism periodically engages and decelerates the film. Once the film has been decelerated, a section of the film is temporarily secured in alignment with the aperture block and an image disposed on the film is projected. The conveyor then moves a secondary shutter into alignment with the aperture block to shutter the aperture block.

Abstract: Film transport device in a film projector with winding plates located on both sides of a film gate and drivable by one winding motor, with supply and takeup devices respectively located between the winding plates and the film gate to create film loops on both sides of the film gate, a film transport device between the supply and takeup devices, and a film channel to guide the film placed in the film projector. After film (1) is placed in the open film channel, film transport device (2) and one of the two supply and takeup devices (3, 4) is brought into engagement with film (1) and film transport device (2) is operated at an rpm greater than that of one of the supply or takeup devices (3 or 4) until a first film loop of a presettable length is formed between film transport device (2) and one of the supply and/or takeup devices (3 or 4).

Abstract: A sprocket drive mechanism for transporting film through a motion picture camera includes a frame and a sprocket wheel rotatably supported on the frame and adapted to engage the film. A drive plate is rotatably supported on the frame which is rotated by a drive mechanism. A knob is coupled to the sprocket wheel for rotation therewith. A coupling plate is rotatably supported on the frame and is axially coupled to the knob for selectively rotating the knob. The knob, where manually actuated, axially displaces the coupling plate between a first position where the coupling plate is engaged with the drive plate for rotation therewith and a second position where the coupling plate is disengaged from the drive plate. The coupling plate, when in the first position, rotates the knob which in turn rotates the sprocket wheel. The knob, when the coupling plate is in the second position, is manually rotatable to permit manual rotation of the sprocket wheel to adjust the film.

Abstract: A telecine projector includes film supply and take-up means; a film constant-speed drive means for advancing the film at an arbitrary predetermined constant speed past a magnetic transducer; a shutter for intermittently illuminating the film at a predetermined constant rate; intermittent film advancing means for advancing the film past the shutter; a film slack detecting means for detecting whether slack in the film between the film advancing means and the film constant drive means exceeds a predetermined amount; and control means for controlling the advancing operation of the film advancing means in accordance with the output of the film slack detecting means. The film can be intermittently advanced in accordance with a film running speed which is arbitrarily predetermined while the shutter operates at the video field frequency. Fast motion reproduction and slow motion reproduction are possible.

Abstract: A film buffer for motion picture projectors is provided to permit the smooth advancement of the film through a projection gate, and to serve as a shock absorber to insure even projection. The buffer comprises a pair of rollers in fixed relation to each other juxtaposed to form a loop in the film in its path of travel, from a film supply reel to a film transport mechanism for incrementally advancing each frame of the film past the projection gate, a bracket for holding said rollers pivotally mounted on the face of the projector at a mid-point between the two rollers to permit swinging movement to increase or decrease the film loop size depending upon the tension of the film, a counterweight fixedly connected to the bracket to pivotally bias the same into a position to increase the film loop size, and a torsion spring positioned beneath the counterweight to engage and cushion the same as it moves toward a rest position.

Abstract: A sound motion picture projection apparatus provided with pressure pad means operable to press a film against magnetic sound recording and reproducing head means disposed along a path of the film for sound recording and/or reproduction. Urging means urge the pressure pad means toward its film pressing position. Externally operable means are provided for shifting the pressure pad means from its film pressing position to a released position against the urging force of the urging means. Releasable locking means are provided for holding the pressure pad means in the released position against the urging force of the urging means; and film detecting means are disposed in said sound film path behind the magnetic head means to detect introduction of the film into the sound film path and to release the locking of the pressure pad means by the locking means.

Abstract: An improved slot load motion picture projector is provided with a cam plate guide assembly connecting the projector control lever with the projector film gate. The cam plate has a cam path formed therein with a cam follower disposed within the cam path. Links connect the cam follower to both the control lever and the film gate. The cam path guide assembly causes the film gate to close during the initial portion of the control lever movement from the load position to the operate position, and causes the film gate to open during the initial portion of the control lever movement from the operate position to the load position.

Abstract: A lower loop restorer for automatically resetting the lower loop of a motion picture projector when the loop is lost. A loop restoring roller, located in the film path, is provided at one end of a pivotable control arm assembly. When the lower loop is lost, the control arm is triggered to cause drive means to pivot the control arm assembly downward and then upward to pull film from the film gate and reset the lower loop. Means are provided to disable or inhibit the operation of the lower loop restoring mechanism when the projector is operated in the reverse projection mode, the in path fast forward mode, or the inpath rewind mode. Means are also provided to protect the film from damage if the lower loop restorer is triggered and film is jammed in the film gate.

Abstract: For a sound motion picture projector, an automatic threading and image-sound synchronization system is provided without added moving components. During threading the system establishes for image-sound synchronization the correct image-to-sound spacing of a film having the sound longitudinally spaced along the film from the related image.

Abstract: An elastic damper which engages the film between the supply reel and the film gate of a motion picture projector has an elongated first leg which loops the film and is pivotable with respect to a second leg which is reciprocable between bridges and is biased forwardly so as to urge the first leg against the film. When the tension of film fluctuates within a normal range, such as is attributable to intermittent operation of the pull-down, the first leg merely pivots while the second leg remains stationary. If the tension of film increases so that the pivotal movement of the first leg is more pronounced, the second leg is shifted against spring bias to effect a reduction of the size of the loop. This insures that the inclination of the film portion between the gate and the first leg remains substantially unchanged.
