Mason jars

The nonwovens iadustry also uses a saline repeUency test, especiaUy for medical fabrics. Fabrics are evaluated for the lapsed time before wetting when a 115-mm column of water ia a mason jar is appUed to the surface (INDA Standard Test 80.5-92). 

RoUed-zinc products in the form of strip, sheet, wire, and rod have many and varied commercial appUcations. Strip is formed into dry-ceU battery cans, mason jar covers, organ pipes, grommets, eyelets, and many other objects, some of which are subsequentiy brass or chromium plated (jewelry, medaUions, bathroom accessories, etc) (132). The zinc—carbon dry-ceU appUcation accounts for about one half the roUed-zinc consumption in the United States (see Batteries). Sheet zinc is used in photoengraving and also in the constmction of roofing and other architectural uses. Special high grade zinc with a... 

Christensen-Mason Jar. (See Figure 4-172 and Table 4-103 [57].) This is a combination tool, offering possibility to jar upwards hydraulically and to bump downward mechanically. The jar is equipped with a special releasing (locking) mechanism, so that the jar cannot be fired upwards until the locking system has been released. It has a 6-in. jarring stroke upwards and 30-in. for downward bumping [57].

The substrate was Valencia orange leaves, with 2500 leaves per sample selected in a carefully prescribed manner (4). The trees involved were field sprayed in a conventional manner with 4 pounds of a 25% wettable powder of parathion, then sampled after 7 days and again after 11 days. Each sample was mixed thoroughly and subsampled into 125-leaf units in 2-quart Mason jars. To all units were added 250 ml. of benzene each, and they were sealed, stripped for various lengths of time, then restripped with fresh benzene, again for various lengths of time. The strip solutions were analyzed in the usual manner. 

Leaves are stripped for 30 minutes in the usual 2-quart wide-mouthed Mason jars. Instead of a waxed paper gasket, however, 2 squares of No. 300 M.S.T. cellophane topped by a square of white nylon are used, as the benzene would disintegrate the wax paper during this longer stripping period. The entire 250 ml. of benzene are added at once, the... 

Powder the 25 G sample and place it into a glass mason jar that has a screw top (make sure the seal on the jar top is not soluble in the solvent). Add at least 125 ml (1/2 cup) of solvent. Screw on the top. Shake well for 2 minutes. Let sit for a minimum of 24 hours (several days might yield a more complete extraction). Shake periodically (at least 5 or 6 times over the course of the extraction period). Then pour the entire contents of the jar though a fine mesh wire strainer (a tea strainer will do). Save all the solvent. With the back of a spoon squeeze the stuff in the strainer dry. Save the solvent that you squeeze out. Re-extract the filtered leaf material in an addition 125 ml fresh solvent. As... 

However you dry the leaves, store them in a sealed jar away from light. A clean glass canning jar works very well (Mason jar). Storing the jar inside a kitchen cabinet or medicine chest will keep it away from light. Stored this way, leaves will retain their potency for many, many years. 

I took approximately 30 dried leaves of Salvia divinorum, crushed them by hand, placed them in a mason jar, and soaked them in about 1/2 cup of denatured alcohol. I let this soak for about 2 hours, then decanted the alcohol into a small rectangular dish, added about 5 crushed leaves, and then set a small fan to speed the evaporation process. Since alcohol will absorb a small amount of water, the last bit of moisture was driven off by preheating the oven to 250 F, turning it off and placing the dish within, completely drying the extract in about 15 minutes. I scraped all material from the dish with a razor blade. 

Setting Point — 69° to 70°. Use the apparatus shown in Fig. The bottle A is of 1 liter capacity, such as a Kerr Mason Jar No 12, and the Pyrex test tube B (1.5 x 7 inch) is held in place by means of tape (a) around the top. A cork stopper (b) serves for holding Pytex test tube C, (1 x 6 inch). Cork stopper (c), inserted in tube C, has three holes, of... 

Samples of Sedan ejecta were collected around the crater lip and along several transects of the ejecta field. A 10-inch diameter hole is dug with a conventional posthole auger at each sampling station. Discrete samples are taken at depths of 6 inches, 1 foot and at 1-foot intervals below that to a depth of 5 or 6 feet. The sample is passed through a 2-mm. sieve and collected into 1-quart wide-mouthed Mason jars. Samples are shipped to the Lawrence Radiation Laboratory (Livermore, Calif.), where aliquots are taken from the jars and lyophilized on a large vacuum manifold. Individual glass traps are utilized on the manifold and extracted water from each ejecta sample is collected separately. The extracted water is assayed for tritium with a model 3375 Packard liquid... 

Culture Conditions of Plants. Red kidney beans were started in sand, transferred to Hoagland s solution in quart Mason jars, and grown under greenhouse conditions. At the time when the primary leaves were fully expanded, and the terminal bud was about 2.5 cm. long, the plants were treated as described later. 

In two subsequent experiments, following foliar and, cotyledon applications, the bean plants were covered with polyethylene bags. To maintain a saturated atmosphere, water was applied daily, so that 1 inch of water covered the bench top on which the plants in Mason jars were growing. 

Water samples (oa 1 L) were collected by immersing clean mason jars to a depth of 1 cm in midstream. Water samples were extracted immediately with dichloromethane as described earlier. Moss samples (oa 300 g) were collected from rocks on the stream bed and packed in polyethylene bags after gently squeezing out adsorbed water. Samples were later cut into small pieces, thor-... 

Crop Extraction and Cleanup (FM0CC1). The extraction procedure found in the Pesticide Analytical Manual (17) was utilized throughout. In this procedure 100 g of chopped crop, 100 ml of chloroform and 200 ml of water were added to a 1 quart Mason jar and blended at medium speed for 15 min. The jar was rinsed with 2 x 20 ml of H2O and the combined contents and rinses distributed equally between three 60 mm x 120 mm polypropylene centrifuge bottles. After centrifugation at 10,000 rpm for 20 min. the aqueous layers were combined and rotary evaporated to 50 ml at which time the pH was adjusted to 1.0 with concentrated HC1.

Emulsion Capacity and Stability. A 0.5 g sample of the freeze-dried protein fraction was redissolved in a minimum of 0.3 M citrate-phosphate buffer at pH 7.0 and mixed thoroughly with 50 ml of 1 M NaCl for 1 min in a Sorvall Omnimixer at 1000 rpm in a one pint Mason jar set in a water bath (20°C). Crisco oil (50 ml) was added to the jar and an emulsion formed by mixing at 500 rpm with simultaneous addition of oil at the rate of 1 ml/min until the emulsion broke. The endpoint was determined by monitoring electrical resistance with an ohmeter. As the emulsion broke a sharp increase (l KS2 to 35- 0 KSi) was noted. Emulsion capacity was expressed as the total volume of oil required to reach the inversion point per mg protein. This method is similar to that used by Carpenter and Saffle (8) for sausage emulsions. To establish emulsion stability the same procedure was used except that 100 ml of oil was added and a stable emulsion formed by blending at 1000 rpm for 1 min. A 100 ml aliquot was transferred to a graduate cylinder and allowed to stand at room temperature. Observations were made of the volume of the oil, emulsion and water phases at 30, 60, 90 and 180 min. 

We also carried out measurements of gases emitted by termites when the Trinervitermes species nest and the Cubitermes species nest were broken down and the termites without the soil nest placed into a 1 litre Mason jar. The soils of the two species nests were also placed into another Mason jar and the air above each jar determined for CO2 and CH4. The number of Cubitermes termites placed into the Mason jar were as follows ...

INDA, the Association of the Nonwoven Fabrics Industry, has published repellency test methods specifically designed for the nonwoven fabric structure. 1ST 80.5(01/ is designed to measure a nonwoven material s abihty to resist gravity-only penetration by a saline solution. This property is useful in assessing the degree of water repeUency needed by nonwovens in a number of applications. A sample of the nonwoven to be tested is placed in the mouth of a quart size Mason jar containing saline solution. The jar is then inverted and placed on an electric grid that senses when the solution has penetrated the nonwoven. The time to complete penetration is recorded as a measure of repellency.
