TAP-CuP

A blanket crepe mbber produced from the dried films and lumps of mbber found in the tapping cups at the beginning of the next tapping. Cup lump results from the spontaneous coagulation of the latex which has dripped from the tree after the cup has been emptied of the main flow. [Pg.20]

The treatment of latex which is to be shipped as latex differs somewhat from that which is to be made immediately into dry rubber. For short-term preservation it is customary to add a small amount of an anti-coagulant to the tapping cups Where the latex is to be concentrated and shipped as such, much greater preservation is necessary and additional ammonia is added, up to about 0.7%. For latex foam manufacture most of this ammonia must be removed, and to eliminate the de-ammoniation operation several low ammonia latices have been developed. [Pg.37]

Latex continues to drip after the initial collection and coagulates naturally in the cup to form cup lump. Coagulum which forms as a film of latex on the tapped cut, called tree lace, or from latex that has dripped onto the ground, called earth scrap, is collected the next day along with the cup lump. Some smallholders may not collect the latex at all, but allow it to coagulate in the cup and collect it as cup lump. AH these methods produce mbber known as field coagulum. [Pg.265]

Soybean dry matter production. One week after planting in the pipes, two-hundred-forty 0.7 liter styrofoam cups with four holes in the lower sides of each were filled with a 2 cm layer of pea gravel, then filled to within 1 cm of the top with a 1/1/1 v/v/v mix of perlite, coarse sand and a sandy loam soil. Each cup was planted with three soybean seed ( Centennial or Coker 136 ) previously coated with Nitragin. The seed were covered with 1 cm of soil mix and watered with tap water. [Pg.236]

Two weeks after planting in the pipes, the plants were thinned to 35 pipe per pipe each and the cups to one plant each, and the treatments begun. Each first, third and fifth day of the week for twelve weeks the pipes were flushed with three liters of tap water poured in the elbow end. The water flowed past the plant root systems and drained out the screened end of the pipes into a flask. One hundred milliliter aliquots of this water ( root exudate ) were used to water the soybean plants in the cups three times weekly. After each flushing, two liters of a low nitrogen (50 ppm N) complete nutrient solution (Peter s Hydro-sol ) were added to each pipe. The soybean plants in cups were watered as needed at other times with tap water. On alternate weeks the soybean plants were fertilized with the complete nutrient solution. At 4, 8 and 12 weeks after the root exudate treatments started eighty soybean plants (10 treatments x 2 soybean varieties x 4 blocks) were randomly chosen for analysis. The soil was washed free of the plant roots and each soybean plant was divided into roots, nodules, stems, leaves and fruits. The plant parts were dried at 105°C for four days and weighed. [Pg.236]

Using a graduated cylinder, measure 40 mL of tap water and pour it into the cup. [Pg.34]

Blanket crepes are of lower quality and are made from wet slabs obtained usually from small landholders. These are creped. dried, and baled. Other types of crepe are made from coagulum left in collection cups and from dried skin remaining from the tapping incision. In addition to collecting latex, a tapper collects all dried and coagulated rubber that remains from die previous round, usually as skin m the cup or on the tapping panel. [Pg.1451]

The cup is removed from the autoclave, and the ampul is transferred into a Dewar vessel filled with liquid nitrogen. The cooled ampul is rolled in several layers of filter paper and opened by tapping with a hammer. This should be done with extreme caution. The contents of the ampul Eire transferred to a porcelain dish, washed several times with methanol, and dried between... [Pg.164]

A sonicator (Model W-370) was purchased from Heat Systems-Ultrasonic with a cup horn attachment. The horn was the resonant body, which vibrated at 20 kHz (20,000 cycles per second) and served as a second stage of acoustic amplification. The standard tapped titanium disrupter horn was immersed in circulating water at 50°C during sonication. [Pg.290]

Put one cup of hot tap water in the two-cup measuring cup. Add one-half cup of sugar to the hot water. Stir the water with a spoon until the sugar dissolves. You can no longer see the sugar when it dissolves. [Pg.12]

As we ve mentioned, pregnant women need to hydrate. A lot. Unless you have the pleasure of working from home all day long—or in an office with a water filter attached to the tap—you re likely to have to get your H20 from a cooler in a plastic cup, or, most likely, from plastic bottles. [Pg.103]

The liquid (tap water) was pumped through the tracer injection fitting, where a determined tracer volume was injected. Before entering the spray nozzle, the liquid flow was monitored for the dye concentration using an optical flow cell. The liquid passed the channels of the monolith and was collected with a small stirred vessel (mixing-cup). From this mixing cup the liquid was led on to a second probe, which measured the dye concentration by spectroscopy. The absorption of light is related to the concentration of the tracer by the Beer-Lambert law. [Pg.245]
