Attachment of the motor to the camera automatically completes the electrical connections through the built-in plugs in the motor and camera base. This feature provides firm, self-aligning, wearcompensating mountings for quick attachment and removal of the motor as well as for extreme simplicity The power-feed receptacle, reverse switch, buckle switch, ON-OFF switch, and red light warning assembly are built as separate units. These electrical assemblies, which are commercially available, may be quickly removed from the camera for replacement or maintenance without disturbing or removing the soldered connections or any parts of the camera. The buckle switch stops the camera and a warning red light flashes when there is loss of loop. Furthermore, when the magazine is improperly positioned the camera will not start. The pendant hand switch and powerfeed cable comprise the external wiring of the camera. Most cameras have the ON-OFF switch on the body of the camera, but in order to eliminate disturbance of the camera by physical contact of the operator during shooting, the switch has been placed on the end of a pendant cord. More important, however, is the fact that the pendant-switch method permits use of relays, timing mechanisms and other remote-control systems as desired. Television Recording As reported in numerous articles on the subject of kinerecording, elimination of the phenomenon known as "banding" or "shutter bar" has been extremely difficult to accomplish either by mechanical or electronic means. It is well known that a motion picture camera equipped with a 288° open shutter and operated at the synchronous speed of 24 frames/sec is used to record standard 30 frame/sec commercial telecasts. However, numerous and apparently insignificant factors including shutter flutter, mechanical Badgley and Fraser: Automatic Threading Camera 55
