scherenschnitte n. Jeri discovered paper cutting, or scherenschnitte in a book on early American art and she’s been doing it ever since. That’s right its called “scherenschnitte,” which is actually a German word for “scissor snipping.” [GermanArts & Literature] [full cite] (Sep. 22, 2005)
schmutzdecke n. Periodically the top layer of sand (approximately 25 to 100m deep) needs to be removed from the slow sand filters together with the associated biological accumulation (“schmutzdecke”) for cleaning. [German] [full cite] (Mar. 16, 2007)
schmutzdecke n. This system, introduced into the U.S. in 1872, uses low water flow rates (0.05 gpm/sq ft) and relies on the formation of a “schmutzdecke” (a fine, mud-like layer) in the top surface of the fine sand (specific gravity of 2.6|+ or -~) for filtering. However, it may take several weeks for the filtration layer to form (during which the “filtered” water is lost) and this type filter is ineffective for high turbidity waters. Cleaning is by scraping off the schmutzdecke and top layer of sand, and placing a layer of new sand. [German] [full cite] (Mar. 16, 2007)
schmutzdecke n. The surface is now a veritable of cat hairs, dead fleas, some dirt I suppose, hair-balls and horked-up Friskies. [German] [full cite] (Mar. 16, 2007)
schmutzdecke n. Most of this gelatinous growth and of the deposited sediment collects in the top half-inch or so of the bed, and combined form what the Germans call schmutzdecke, which term has been adopted in this country. This schmutzdecke acts as a finer straining medium for removing bacteria and other suspended matters. [German] [full cite] (Mar. 16, 2007)
schmutzdecke n. After the filter has been operated for some time a gelatinous layer (Schmutzdecke of Piefke) is formed of such imperviousness that each square meter of surface will no longer furnish as much as 3 cubic meters (800 gallons) of water in twenty-four hours.…Whenever the demand for the filter is not too great it is allowed to rest after cleaning for some time, in the belief that those particles of the dirt deposit (Schmutzdecke) which have penetrated unto the lower layers will be oxidized under prolonged contact with the air.

schmutzdecke n. This type of filter works because of a biological microbe named schmutzdecke. It grows on top of the sand and its job is to eat organisms in the water. It can take up to two weeks to form so any water before that is not fit to drink. Also, to keep ol’ Schmutzy alive you need to keep the water level above the sand at all times.

schnitting n. Archeologists use a flat-bottomed shovel to shave exposed layers of earth in the squares, to make a clean edge across the surface, and to keep it fairly level. The process is called “schnitting,“according to Dave Hazzard, director of the threatened archeological sites program at the Virginia department of historic resources, and a principal at this site.

sitzprobe n. The sitzprobe—the German word originally came into musical theater from the world of opera and literally means “sitting trial”—is actually the rehearsal at which cast and musicians assemble to play through a score for the first time and hear the combined results of their separate endeavors.

sitzprobe n. I looked at the schedule and said “What’s a sitzprobe?” and they said “don’t you know? Oh dear, you are ignorant.” It’s a German word which means sitting down and singing with the orchestra. First band-call, I would have called it. [GermanEntertainmentMusic] [full cite] (Mar. 2, 2005)
