The hose couplings, buoyancy control (air pressure) and method of initiation (by Prima-cord) were the same as for the NOL Streamer in Use at that time. The only apparent weakness of the duPont streamer was that the pellets were broken to some extent by handling and countermining. The disadvantage of foe pellet load was largely eliminated by the EL development of a blend of flaked and grained TNT for use in the NOL canvas sock... 

Two infrared absorption methods (i.e., FTIR) and a Raman spectroscopic method were used to quantify polymorphic clopidogrel bisulfate Form-I and Form-II [16,17]. In addition, qualitative analysis of these polymorphs was also conducted using FTIR [16], where each sample was scanned over in the spectral region of 450-4000 cm-1 at a resolution of 4 cm-1. The sampling procedure used KBr pellets, loaded to contain approximately 3% of analyte. It was found that absorption bands associated with C-Fl and C-O bonds were stronger for Form-II relative to Form-I, and that unique absorption bands for Form-I and Form-II were observed at 841 and 1029 cm-1, respectively. These absorption bands were reported to be useful in the quantitative or qualitative analysis of clopidogrel polymorphs.

Table 4 shows, the sources are available with physical sizes ranging from 1 mm x 1 mm up to 3 mm x 3 mm. They are produced from firmly compressed selenium pellets of cylindrical shape. The activities range up to 3 TBq or 80 Ci, which is the maximum allowed loading of the GammaMat SE portable isotope transport and working container, as well as the Source Projector M-Se crawler camera. 

Most commercial adsorbents for gas-phase appHcations are employed in the form of pellets, beads, or other granular shapes, typically about 1.5 to 3.2 mm in diameter. Most commonly, these adsorbents are packed into fixed beds through which the gaseous feed mixtures are passed. Normally, the process is conducted in a cycHc manner. When the capacity of the bed is exhausted, the feed flow is stopped to terminate the loading step of the process, the bed is treated to remove the adsorbed molecules in a separate regeneration step, and the cycle is then repeated. 

While the rotary dryer shown is commonly used for grains and minerals, this system has been successfully applied to fluid-bed diying of plastic pellets, air-hft diying of wood fibers, and spray drying of milk solids. The air may be steam-heated as shown or heated By direct combustion of fuel, provided that a representative measurement of inlet air temperature can be made. If it cannot, then evaporative load can be inferred from a measurement of fuel flow, replacing AT in the set point calculation. 

Uniform depth of loading in dryers and furnaces handling particulate solids is essential to consistent operation, minimum heating cycles, or control of final moisture. After a tray has been loaded, the bed should be leveled to a uniform depth. Special preform devices, noodle extruders, pelletizers, etc., are employed occasionally for preparing pastes and filter cakes so that screen bottom trays can be used and the advantages of through circulation approached. 

Canister working eapaeity was studied for a 1.27 mm mean diameter granular versus 2.1 mm mean diameter pellet earbons of equal BWC. Under the ORVR loading eonditions the granular earbon had a 6-12% higher GWC. However, the high pressure drop of the granular earbon would make it very diffieult to use in an ORVR system. 

The plot in Fig. 13 shows the bleed emissions that were measured after a 24 hour soak. Two eanisters were tested, one loaded with a wood granular carbon with a mean particle diameter of 1.27 mm, the second with a wood pellet carbon with a mean particle diameter of 2.10 mm. Both carbon samples had equal BWC of 11.4 g/lOOml. Although both earbons had the same BWC, the larger pellet earbon had lower bleed emissions. These diffusion results are expected in light of Pick s Law. 

The reactor volume is calculated from Mj and the bulk density of the catalyst material, (-r ) depends not only on composition and temperature, but also on the nature and size of the catalyst pellets and the flow velocity of the mixture. In a heterogeneous reaction where a solid catalyst is used, the reactor load is often determined by the term space velocity, SV. This is defined as the volumetric flow at the inlet of the reactor divided by the reaction volume (or the total mass of catalyst), that is...
