The keynote in the design is high-quality projection continuously over a long period of time without the necessity of costly periodic factory overhauls and replacement of parts. Over ten years of field experience with the Brenkert BX-80 projector mechanism has shown that automatic lubrication, a heavy rugged type of gear train, double rear shutters, unit construction and ease of serviceability are features essential to this objective. These features, together with new additions necessary to meet present-day requirements will be described in this paper.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Journal/smptej_55_3/10.5594_J09476.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "articleType": "research-article", "articleType$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Journal/smptej_55_3/10.5594_J09476.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ "H.
