We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
necessary to sacrifice a frame or frames, Insert an equal number of frames of opaque leader so that the two reels will always remain matched, and run sound from the unpatched reel.

This can be done by remounting it on a suitable block of wood or, preferably, by having an iron strap support bent to shape by any local iron worker. MOTIOGRAPH MECHANICAL INTERLOCK This equipment provides synchronous operation of two projectors for the presentation of third dimension pictures. It is designed for operation with the SH-7500 sound reproducers and projectors which are driven with the SH-7030 mechanism drive. A minimum of seven inches clearance between the front of the soundhead and the front wall (at zero pro jection angle) is required to provide proper mounting of the gear boxes. With this condition (zero angle) the cross shaft is SIVa inches above the floor and 3 inches from the front wall. With a ten degree angle the shaft is 28 inches above the floor and 6 inches from the front wall. Any boxes or cabinets on the front wall must clear this shaft which revolves at a speed of approxi mately 50 RPM. If desired a sheet metal shield fastened to the front wall can be used to cover the cross shaft. The gear boxes are shipped dry and should be filled to the check plug level with Texaco 650T cylinder oil, Shell Valvata oil J-83, or one of the other oils listed under Oil No. 8, in the Eberhardt Denver Com pany lubrication bulletin No- 23, which is packed with each gear box. The usual precautions should be taken to see that the projection room temperature is not too low when starting the machines.
