Wedge hopper design charts are used in the same way as the conical design charts. If is 15°, the resulting maximum wedge hopper angle for mass flow is 40° from vertical. This is 12° less steep than the required conical hopper angle. Mass flow wedge-shaped configurations require significantly less headroom than conical hoppers. The side walls of transition- and chisel-shaped hoppers can be designed based on 0 provided the outlet length-to-width ratio is at least 3 1.  [c.555]

The cyclic chalcogen imides are saturated ring systems involving two-coordinate chalcogen atoms and three-coordinate nitrogen atoms. Their formulae can be written without double bonds, but structural data indicate limited involvements of the nitrogen lone-pair electrons in tz-bonding with the adjacent sulfur atoms. The best known examples of cyclic sulfur imides are eight-membered rings in which one or more of the sulfur atoms in cyclo-S are replaced by an imido [NH or NR (R = alkyl)]. This class of compounds has an important place in the history of chalcogen-nitrogen chemistry and the developments in the field up to 1979 were covered comprehensively in the book by Heal. Since that time a number of sulfur imides with ring sizes either smaller or larger than eight have been discovered (Section 6.2.2). In addition, a series of cyclic imides of the heavier chalcogens, notably selenium, have been prepared and structurally characterized (Section 6.3). This chapter will begin with a review of the salient features of the chemistry of cyclic sulfur imides. This summary will be followed by a discussion of the aforementioned recent aspects of the chemistry of cyclic chalcogen imides with an emphasis on the differences observed for the heavier chalcogen systems compared to their better known sulfur analogues.  [c.111]
