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.

The sample sheet opposite shows fade-overs from one record to another. There is also an example of the use of both pick-ups on the same record; thus Train Effect (b) ('Train Starting") is followed rapidly by Train Effect (c) ("Train in Motion"). Although these two effects are recorded on the same disc, a fade-over is possible from one to the other if you play the record on the right-hand turntable. Play effect (b) with pick-up No. I which can be swung to operate on either turntable. Make the fade-over to pick-up No. 2 which is playing effect (c) on the same record. Then swing pick-up No. I back to the left-hand turntable ready for a fade-over to the record waiting on it. Locating Points A rather similar problem arises with records. After a while you may become quite adept at finding a selected passage at the first attempt. Your presentation can become more polished and certain, however, if you have a positive way of indicating the passage required. The old dodge of previously marking the appropriate groove with a chalk mark is likely to damage the record, particularly the longplaying type. A more satisfactory arrangement consists of a pointer swung by the pick-up across a graduated scale. Enter on the cue sheet the scale marking corresponding to the required passage on the record. Then you have only to swing the pick-up to repeat the scale reading in order to lower the needle in the right groove. When attaching such a pointer to the pick-up, remember to make it extremely light. Modern pick-ups operate with stylus pressures of less than half an ounce. A clumsy pointer will more than double this pressure and damage the records. If your record player has an automatic brake, you will find it almost essential to disconnect it for mood music This typical groove-locating mechanism may be used with standard pick-ups. Turning the setting knob moves the locating shoulder along the lifting bar supporting the pick-up arm. When the scale reading is correct, the dropping lever is depressed, allowing the lifting bar to lower the pick-up gently on to the record. B Setting Knob Locating Shoulder Scale 29
