Maxim powder

Maxim Powder. One of the varieties of sm.oke-less powd invented by Hudson Maxim, contg guncotton 94, NG 5 castor oil 1%. It was. used in the form of either small square flakes or cylinders, 1.64 inches long and 0.5 inch ill diam. Other varieties of Maxim powds contd equal parts of NG and guncotton without castor oil... 

Figure 12-94a shows a cocurrent cone-based tall form chamber with roof gas disperser. This chamber design is used primarily with pressure nozzle atomization to produce powders of large particle sizes with a minimum of agglomeration. The chamber can be equipped with an oversize cone section to maximize powder discharge from the chamber bottom. This type of dryer is used for dyestuffs, baby foods, detergents, and instant coffee powder. 

Increase adhesion tension. Maximize surface tension. Minimize contact angle. Alter surfactant concentration or type to maximize adhesion tension and minimize Marangoni effects. Precoat powder with wettahle monolayers, e.g., coatings or steam. Control impurity levels in particle formation. Alter crystal hahit in particle formation. Minimize surface roughness in milhng. 

Platinum and palladium are the most common catalysts for alkene hydrogenations. Palladium is normally used as a very fine powder supported" on an inert material such as charcoal (Pd/C) to maximize surface area. Platinum is normally used as PtC, a reagent called Adams catalyst after its discoverer, Roger Adams. 

Maxim-Schupphaus Powder. A progressive burning smokeless powd, invented by Hudson Maxim in collaboration with R.D. Schiipphaus. 

N57. An older Italian proplnt used in 57mm guns. Its compn was similar to that of the American Maxim-Nordenfeldt powder (see in this Vol, p M46-R Ref Daniel (1902), 448... 

The signal is maximal for 0 = 0, and rotating B (and / ,) away from the molecular z-axis causes a rapid divergence of linewidth and intensity. Thus, the powder spectrum is obtained as the integral... 

In addition, compression methods that utilize hydraulics and levers may be used. These sometimes have pressure gauges that allow the analyst to apply a certain optimal force in order to maximize the chances of making a quality pellet. To make a quality pellet, in addition to using the optimum pressure, it is important for the KBr and the sample to be dry, finely powdered, and well mixed. An agate mortar and pestle is recommended for the grinding and mixing of the KBr and sample prior to compression. See Workplace Scene 8.3.
