Hydrocarbon mixtures can be assumed to be regular solutions it is thus possible to estimate the activity coefficient using a relation published by Hildebrandt (1950) ... 

Immersion-type extractors have been made continuous through the inclusion of screw conveyors to transport the soHds. The Hildebrandt immersion extractor (18) employs a sequence of separate screw conveyors to move soHds through three parts of a U-shaped extraction vessel. The helix surface is perforated so that solvent can pass through the unit in the direction countercurrent to the flow of soHds. The screw conveyors rotate at different speeds so that the soHds are compacted as they travel toward the discharge end of the unit. Alternative designs using fewer screws are also available. 

The Hildebrandt total-immersion extractor is shown schematically in Fig. 18-80. The hehx surface is perforated so that solvent can pass through countercurrently. The screws are so designed to compact...

Thehaine stands at the other end of the series from morphine and is a convulsant poison rather than a narcotic (see table, p. 261). Hildebrandt states that it excites the reflexes of cold-blooded animals but in dogs it exerts a narcotic and anti-emetic effect resembling that of morphine rather than that of chloromorphide. The alkaloid is scarcely used in medicine as such, but is a primary material for the preparation of certain of the modern morphine derivatives, such as hydroxydihj dro-codeinone and methyldihydromorphinor.e.

The secretion of the polymer into the growth medium is not only a means to control nuclear /3-poly(L-malate) concentration but also is a prerequisite for spor-ulation. L-Malate, which is a co-inductor of sporulation (Renzel and Hildebrandt, personal communication), is obtained by spontaneous and polymalatase-catalyzed hydrolysis of the secreted polymer.
