Abstract: A noise and/or vibration damping system for an electric motor such as for use with a sound motion picture camera. In a preferred embodiment the electric motor includes a rotor shaft supported at either end thereof by bearings, a magnetic field assembly fixed to the motor case and concentrically positioned between the rotor shaft and the motor case, an armature winding assembly fixed to the rotor shaft concentrically positioned between the motor case and the magnetic field assembly, wherein the bearing means are supported upon the magnetic field assembly and are vibrationally isolated therefrom by plurality of O-rings concentrically positioned between the bearing means and the magnetic field assembly, the O-rings being axially spaced along the magnetic field assembly.

Abstract: A film magazine is provided adapted for running the film stored therein either forward or backward. A first brake within the film magazine provides a drag torque on the supply hub when the supply hub rotates in the forward direction but not when it is rotating in a backward direction. In addition, a second brake is provided for exerting a drag torque on the take-up reel when the take-up reel is rotating in a backward direction, but not when it is running forward.The brakes and motors within the film magazine are adapted so as to keep tension on the film at all time.

Abstract: A lens system is provided for being coupled to a camera. The lens system has two prime lenses for receiving light from objects being filmed. Light passing through the prime lenses is reflected by a pair of prisms and a pair of mirrors to a relay lens. Light from the relay lens is used to expose the film in a conventional movie camera so that the image from one prime lens is recorded above the image from the other prime lens. Each film frame is divided in half, one half storing the image recorded by one prime lens, the other half storing the image recorded by the other prime lens. The two prime lenses are displaced both vertically and horizontally. As the two prime lenses are focused by being moved horizontally, one of the prime lenses moves vertically to insure that the object being focused on appears at the same height within its half frame as the object appears in the half frame storing the image from the other prime lens.

Abstract: A film magazine for a motion picture camera contains apparatus for maintaining the tension in the film strip from the supply reel and in the film strip to the takeup reel, within predetermined limits, to permit start-and-stop operations of the camera while minimizing danger of damage to the film. The supply reel is connected to an eddy current brake, and a takeup reel is powered by a motor responsive to a tension control device. The eddy current brake on the supply reel provides braking torque of relatively high magnitude when the supply reel is large in diameter, and the braking torque reduces gradually to a minimum as the diameter reduces.Tension in the film strip leading to the takeup reel is controlled by a tension measuring device which acts to vary the power delivered to the motor driving the takeup reel, to obtain uniform winding tightness.

Abstract: A body-mounted support device for a motion picture camera employs a pair of serially connected articulated arm assemblies attached to a body harness and positioned to support a gimbal device. A camera support tube is mounted on the gimbal device and carries a motion picture camera on its upper end, and a battery and, optionally, the camera motor, at its lower end. Pneumatic cushion means associated with the articulated arm assemblies dampen unwanted movements of the motion picture camera. An emergency release mechanism is provided to disconnect the entire device from the body harness. Telescoping parts of the camera support tube permit the camera to be operated from a very low elevation with respect to the floor. The battery carrier at the lower end of the support tube has a portion which may be swung to one side so that gravity may bring the camera support tube into vertical position.

Abstract: A body-mounted support device for a motion picture or television camera employs a pair of articulated arm assemblies attached to a body harness and positioned to support a gimbal device. A camera support tube is mounted on the gimbal device and carries the motion picture or television camera on its upper end, and a battery at its lower end. Pneumatic cushion means associated with the articulated arm assemblies dampen unwanted movements of the motion picture camera. An emergency release mechanism is provided to disconnect the entire device from the body harness. Telescoping parts of the camera support tube permit the camera to be operated from a very low elevation with respect to the floor as well as allowing vertical adjustment of the center of gravity of all of the parts supported upon the gimbal device.

Abstract: A body-mounted support device for a motion picture camera or television camera employs a pair of articulated arm assemblies serially connected and attached to a body harness and positioned to support a gimbal device. A camera support tube is mounted upright to turn on the gimbal device and carries a camera on its upper end, and a battery at its lower end. Two-axis horizontal adjustments are provided for the camera at the top of the support tube. Pneumatic cushion means associated with the articulated arm assemblies dampen unwanted movements of the motion picture camera. Tilt adjustments near a belt portion of the body harness serve to position the camera support tube at the desired position in space in front of the cameraman. Provision is made for right hand or left hand mounting of the arm assemblies. An emergency release mechanism is provided to disconnect the entire device from the body harness.
