The intermittent movement in these projectors is usually provided by a Geneva drive, also known as the Maltese Cross mechanism.
2.
On February 21, 1893, a patent was issued for the system that governed the intermittent movement of film in the Kinetograph.
3.
It projected six pictures from a long slide and used a hand-cranked mechanism for intermittent movement of the slide and synchronized shutter action.
4.
"Ozbourn " returned to Long Beach 6 September 1968 and remained there, with intermittent movements to Portland and San Diego, for the next year.
5.
;KS perfs : Because BH perfs have sharp corners, the repeated use of the film through intermittent movement projectors creates strain that can easily tear the perforations.
6.
To avoire infringement on Edison's motion photo patents, the Mutograph camera used continuous movement friction rollers to move 68 mm film into the camera, instead of intermittent movement by sprockets as Edison's 35 mm camera did.
7.
An ingenious device for producing an intermittent movement without sprocket wheels or cogs is one of the features of the camera, while its lightness and facility of operation makes it adaptable for use in most any place.
8.
With the slow obsolescence of the Mitchell cameras, which likely took so long because they were so well regarded in mechanical design aspects, such as their steady intermittent movement registration ( " Compensating Link " movement ) and strong mounts, the mounts have gradually become less common in the past two decades, but remained an option for third party cameras produced as recently as the 1980s.
9.
The facts in sum are : ( a ) a patent solely for the intermittent movement apparatus was issued in February 1893; ( b ) all the other elements of the original Kinetograph patent applications were successfully challenged; and ( c ) a patent, number 589, 168, for a complete Kinetograph camera, one substantially different from that described in the original applications, was issued on August 31, 1897.
