Pocket design

The compressor manufacturer can control items a-c, e, f, and h however, the control of clearance volume at high compression ratios for gases/vapors with low specific heat ratios is of great concern. Compression efficiency is controlled by the clearance volume, valves, and valve pocket design. A decrease in compression efficiency leads to increased power requirements. ... 

We have been investigating these reactions from the standpoint of stereochemically controlling the reaction at the metal site by designing metalloporphyrins with a shape- and size-selective pocket at the metal center. The pockets designed so far are small, and thus... 

The type of roll surfaces has a marked effect on the overall production throughput of a roller compaction process (Fig, lO). A variety of roll surfaces and configurations are available depending on the compaction behavior of the material. For instance, powders that tend to stick or cling to the roll surface requires the use of smooth or circumferential grooved surfaces, while materials that release cleanly from the roil after compaction may be pressed with one of the pocketed design or rolls with grooves in the axial direction. 

Although the technique has been used with only three pocket designs, some general conclusions have been drawn from the work ... 

This paper presents various flaskless loading pocket designs and the production impacts associated with their design. 

Figure 4 illustrates a conveyor direct loading skip arrangement. It is a fairly simple loading pocket design that requires only a transfer chute to direct the ore prior to the conveyor reaching full speed. 

All metal parts exposed to the room are made of stainless steel and motors and transmissions are IP 65 to withstand the eflfect of the cleaning agents. The design also takes into account the special considerations necessary for food processing machinery with regards to easy accessibility to all parts and the lack of corners, edges, pockets or other food traps , so that the mechanical system can be easily cleaned. 

The molecular surface of receptor site regions cannot be derived from the structure infoi mation of the molecule, bth represents the form ofthe active site of a protein surrounded by a ligand. This surface representation is employed in drug design in order to illustrate the volume of the pocket region or the molecular interaction layers [186. ... 

Labyrinth seals are simple to manufacture and can be made from conventional materials. Early designs of labyrinth seals used knife-edge seals and relatively large chambers or pockets between the knives. These relatively long knives are easily sibject to damage. The modern, more functional, and more reliable labyrinth seals consist of sturdy, closely spaced lands. Some labyrinth seals are shown in Fig. 10-107. Figure 10-107 7 is the simplest form of the seal. Figure... 

Circulation of air at velocities of I to 10 m/s is desirable to improve the surface heat-transfer coefficient and to eliminate stagnant air pockets. Proper air flow in tray dryers depends on sufficient fan capacity, on the design of ductwork to modify sudden changes in direction, and on properly placed baffles. Nonuniform airflow Is one of the most serious problems in the operation of tray di yers.
