Sealed Box

different reactor designs are discussed in order of increasing technical complexity, and thus, increasing cost. Char quality also improves through the list, but none produce a quality char comparable to carbon black in most applications, even after upgrade. 

The sealed box is the simplest but most labor intensive process. In this process, whole tires are stacked manually in a steel cylinder equipped with airtight heads on each end. Heat is added either externally or directly inside the reactor until the reactor reaches the desired pyrolysis temperature. The reactor is then held at that temperature for several hours. Next the reactor is cooled, opened, and manually cleaned to remove char, wire, and fabric. It is

Initially devised to measure interactions in single soap films (air/water/air) [8], the TFB technique has been progressively improved and its application has been broadened to emulsion films (oil/water/oil) [ 12] and asymmetric films (air/water/oil or air/water/solid) [13,14]. In a classical setup, a thin porous glass disk is fused on the side to a capillary tube and a small hole is drilled in the center of the disk. The liquid solution fills the disk, part of the capillary, and a thin horizontal film is formed across the hole. The disk is enclosed in a hermetically sealed box, with the capillary tube exposed to a constant reference pressure Pr. Under the effect of the pressure difference AP between the box and the reference, the... 

For this purpose, the flow tube emptied directly into a high-pressure ion source. This source was essentially a sealed box with a gas inlet for the Cl reagent gas, a 0.58 mm hole to allow injection of a magnetically collimated electron beam, and a 0.99 mm hole to allow ions to exit into the mass spectrometer. The flow tube was coupled to the source using a 0.1 mm annular gap that thermally isolates the source from the flow tube, but allows little of the gas flow to escape. Even at a flow tube temperature of 1000 K, the source temperature increased no more than 50 K. To avoid any variations in source conditions with flow tube temperature, the source was thermostated to a constant temperature of 100 K. 

Strip or tubular powder is usually damped by placing it in a room, either on shelves or on grids standing on the floor, on which vessels of water are placed or water is spilled. A sample of powder is taken every few hours and its moisture content is determined. After one or more days, when the moisture content reaches the standard specification, the powder is taken out of the damping machine and poured into sealed boxes. 

The second rig involved the release of approximately 2 kg of hot alumina from an electrically heated hopper in a sealed box. The alumina was dropped onto a plate at the bottom of the box and the dust liberated during the fall and subsequent impact was collected in petri dishes and weighed to determine the specific dust generation rate G = (dust liber-ated/mass of parent material). The motivation for this work came from the need to understand the fundamentals of dust generation during hot solids handling processes, such as those involved in cement and coke production. 

Inside a sealed box there will be evaporation as long as the atmosphere is not saturated with vapor. After that no further loss by evaporation is possible. But any condensation of water on the lid or on the walls of... 

How many half-lives of radon-222 have passed in 11.46 days If 5.2 x 10 g of radon-222 remain in a sealed box after 11.46 days, how much was present in the box initially Refer to Table 2. 

C. Initially, there is 600 mL of solution in A and 100 mL of solution in B. As the solutions stand in the sealed box, their volumes change slowly for a while. When they stop changing, beaker A contains 400 mL and beaker B contains 300 mL. It is then determined that the solution in A is 1.5 M in fructose and has a density of 1.10 g mL. ... 

Two beakers are placed in a sealed box at 25 °C. One beaker contains 30.0 mL of a 0.050 M aqueous solution of a nonvolatile nonelectrolyte. The other beaker contains 30.0 mL of a 0.035 M aqueous solution of NaCl. The water vapor from the two solutions reaches equilibrium, (a) In which beaker does the solution level rise, and in which one does it fall (b) What are the volumes in the two beakers when equilibrium is attained, assuming ideal behavior ... 

In this paradox, a hypothetical cat is placed in a sealed box with an apparatus that will randomly trigger a lethal dose of poison to the cat (as morbid as that sounds). According to some interpretations of quantum theory, until the box is opened and the cat is observed, the cat must be considered simultaneously alive and dead. 

Put a few drops of lacZ substrate on each slide and add coverslips. Seal box with parafilm and aluminium foil and incubate at 31°C overnight. 

Sample boxes must be randomly obtained. Cuts that are only partially boxed are not ready for the final stahstical audit and should not be audited until all boxes are complete. Samples must be randomly obtained from finished sealed boxes. 

An examination will be made at very low frequencies, at the system low-frequency resonance frequency where the net series reactance becomes zero, at intermediate frequencies above resonance, and at high frequencies. For these frequencies the general model of Fig. 1.22 can be specialized into four cases as shown in Fig. 1.24. For very low frequencies, typically 20 Hz or less, the dominating series impedance is that associated with the combined stiffness of the suspension and the air in the sealed box. This presents an overall mechanical impedance whose magnitude is K -F Ki)/a>, thus the velocity, which is proportional to the reciprocal of this quantity, increases directly as the frequency increases. The radiated power, however. 

Before tissue section, the tissues were first put into a sealed box with dry ice to equilibrate at respective temperature for 60 min. 

Slides are then placed m a sealed box containing silica gel wrapped in a paper towel, and stored at 4 C. Slides can be stored for several mo without any effect on the quality of the ISH...
