Handling Flexibility

In most cases, a local description of the flexibility is also required to handle flexible and rigid parts of molecules. Therefore, both bond flexibility indices and molecular flexibility quantification were proposed. 

For materials that are bad to handle, flexible linings in weigh hoppers are often utilised, so that an air blast can be used to dislodge any material sticking in the hopper. Silos often use baffles to prevent too much weight causing pressurised material to bridge. 

As this short example shows. PDB files use different syntax for different records and both writing and reading such files require much effort. Another problem is the extensibility of this format to handle new kinds of information, which further complicates the file structure. The Protein Data Bank has been faced with the consequences - the existing legacy data comply with several different PDB formats, so they are not uniform and they arc more difEcuh to handle (145, 155, 157]. As mentioned in Section 2,9.7.1, there is a much more flexible and general way of representing molecular structure codes and associated information - the STAR file format and the file formats based on it. 

Spatulas. Stainless steel, nickel and porcelain spatulas are available commercially. Some of these are shown in Fig. 11,1, 9 (a) is a spatula with a flexible stainless steel blade and is provided with a wooden handle (6) is a nickel spatula and has a tumed-up end to facilitate the handling... 

Process and Equipment. Rigid polyurethane foam processes use the same high or low pressure pumping, metering, and mixing equipment as earher described for flexible foams. Subsequent handling of the mixture is deterrnined by the end product desired. 

Because of the stringent U.S. requirements on handling lead-based powders, these stabilizers are only found in flexible electrical wire insulation in the United States because no other stabilizers have been developed which have the low conductivity afforded by these materials. 

The flash roaster is flexible ia handling various flotation concentrates and reaching the degree of desulfurization desired, ie, 0.5—3.0% sulfate sulfur. Waste heat is easily recovered. However, grinding and rabbling must be done mechanically. 

Not every polymer can be manufactured successfully into a contact lens. Several important properties for both ocular physiology and patient handling are required of a material for a contact lens appHcation (1,11). In addition, the type of lens appHcation, ie, rigid, flexible, or soft, will dictate the range and importance of the key properties. 

Elastomer Impression Materials. Dentistry requires impression materials that are easily handled and accurately register or reproduce the dimensions, surface details, and interrelationship of hard and soft oral tissues. Elexible, elastomeric materials are especially needed to register intraoral tooth stmctures that have undercuts. The flexibility of these elastomers allows their facile removal from undercut areas while their elasticity restores them to their original shape and size. 

Being highly flexible, arc ideal for material handling... 

Flexible element couplings tend to be somewhat heavier than the comparably rated gear coupling. On a retrofit, heed the earlier warning about lateral criticals. The coupling can handle axial misalignment but is more restrictive than the gear type.
