Abstract: A method and apparatus for regulating the speed of a multitrack audiotape machine while recording audio from a multitrack audiotape onto a videotape. The speed of the audiotape machine is regulated by correlating a video synchronization signal previously recorded onto the audiotape with a video synchronization signal controlling the videotape recorder during the recording. Highly accurate synchronization between the two machines is achieved. This allows for the transfer of multiple audio tracks from the multitrack audiotape onto the videotape and then onto multiple laser videodiscs, such that during playback of the multiple laser videodiscs, the laser videodisc players can be synchronized with each other.

Abstract: A photographic process is provided for transferring an animation sketch or the like from paper onto a transparent cell for use in making animated motion pictures and the like. The animation sketch on paper is photographed to produce a negative of the sketch which is then used as a mask during exposure of a transparent cell bearing a light-sensitive dye film of selected color. Masked portions of the dye film are removed from the cell leaving the exposed cured portions defining a replica of the animation sketch to form a so-called cartoon cell. The thus-formed cartoon cell is backed-up with color as required and composited with other cells having other sketches transferred thereto to form an animation scene.

Abstract: A camera assembly is provided for photographing a scene or subject from two slightly different positions with controlled three-dimensional effects for subsequent viewing, for example, with the assistance of special eyeglasses having appropriately filtered lenses. The camera assembly comprises a pair of cameras, such as two motion picture cameras, mounted onto a rigid frame for photographing a common scene or subject, with one of the cameras receiving light transmitted through a beamsplitter and the other camera receiving light reflected from the beamsplitter. One of the cameras is stationary on the frame whereas the other camera is movably supported by a mechanical control linkage to controllably vary three-dimensional effects by adjusting the lateral or interocular spacing between the nodal points of lens units for the two cameras and further by adjusting the movable camera to select the point of intersection, or convergence distance setting, of the camera sight lines within their fields of view.

Abstract: A turntable bearing tracks at a switching point in an amusement ride course, or other vehicular path having tracks, utilizes two linear induction motors, one for rotating the turntable and one for latching the turntable at selected rotational positions. The linear induction motors are mounted beneath the turntable and operate with an extremely high degree of reliability.

Abstract: An automated camera control drives a video or motion picture camera along multiple independent axes of movement to position the camera for recording an image of a field of view, typically focused upon a model or artwork in special effects motion picture photography. Key position coordinates are manually defined for specific frames of film in a film transport. The automated system generates axial coordinates at each intermediate frame and drives the camera to the intermediate positions thereby defined, as well as the several key positions defined manually. The camera is mounted upon a carriage and a model can also be mounted in relation to the camera and moved in coordinated fashion along a multiplicity of axes. The system accepts manual additions of specified key positions and position data, and the key position information can be edited or deleted.

Abstract: An optoelectronic amusement device has a transmitter that emits pulses of a controlled pulse train duration, pulse rate and pulse width, and at a frequency of at least about 1800 hertz. A receiver is employed which is sensitive to the pulse rate and frequency of the transmitter. The transmitter is incorporated into a firearm replica for a shooting gallery and the receiver is a target displaying a visible light source which is extinguished for a predetermined time period when energy from the transmitter strikes the target.

Abstract: An artificially animated face with three-dimensional facial features formed of a flexible material is provided with remotely actuable concealed mechanisms for manipulating the jaw, rounding the mouth, and drawing the lower lip inward relative to the upper lip. The face is operated by an audio input either from a microphone or from an audio tape. The audio input is fed both through an audio amplification system to a speaker located proximate to the face, and also to an audio encoder which senses the major frequencies of the spoken sounds of the audio input and produces one or more digital signals in response thereto. If an "F" sound is detected, the lower lip of the figure is drawn inward to a slight degree, thus simulating human lip movement in sounding the consonant "F". If the decoder detects an "O" sound, the mouth is rounded in response thereto. If the decoder detects an "A" sound, the mouth is drawn into a line.

Abstract: An optoelectronic communications system in which the transmitter has controlled pulse train duration, pulse rate and pulse width, and a receiver which is sensitive to the pulse rate of the transmitter. The transmitter is incorporated into a firearm replica for a shooting gallery and the receiver is a target displaying a visible light source which is extinguished for a predetermined time period when energy from the transmitter strikes the target.

Abstract: A target control is provided for an amusement device to propel a target in translational motion along a predetermined path and to accelerate the movement of the target when it is struck by a beam of radiation. Preferably, in addition to accelerating the target, the target control reverses the direction of target movement. In this way a visible indication is given to a viewer that the target has been hit, yet the target is still available for further beams of radiation to be directed at it.

Abstract: A light gun for use on moving vehicles produces continuous visible light for aiming purposes and selectable modulated infrared frequencies for actuating a target. The optical path through the gun is transparent to visible light while the infrared portion of the spectrum is modulated by a tuning fork chopper and selectively gated into the optical path by means of an infrared filter, the position of which is controlled by the trigger of the gun.

Abstract: There is disclosed a high capacity passenger transport apparatus which may be employed as a ski lift including a high speed main cable ascending up a ski run and driven at high speeds. A pair of first and second shuttle tracks lead from the downhill run of such cable at the bottom station and separate to pass through respective first and second loading areas and then merge back together at the uphill run of the high speed cable. Chair trucks are carried on the main cable and include releasable grippers gripping such cables and are intercepted at the end of their downhill travel by escort cars which decelerate such trucks and escort them past a selector switch to direct alternate ones thereof onto the respective first and second shuttle tracks and then to a stopped position at the loading area so skiers can be loaded thereonto.

Abstract: A track for vehicles which is particularly adapted for amusement park rides having a plurality of banked curves. The track comprises a pair of track rails connected to a lower backbone pipe. In curved sections, the plane of the track rails extends at varying banked angles around the course line of the track. In such sections, the distances between the plane of the track rails and the backbone pipe varies in direct relationship to the bank angle of the curve. The distance between the plane of the track rails and the course line remains constant. The plane of the backbone pipe also remains parallel to the plane of the course line. The course line is preferably disposed a substantial distance above the plane of the track rails.
