Abstract: A supply of steam is fed to a drying cylinder (10) from a steam line (20) through a steam pressure control valve (22). Condensate and steam are removed from the drying cylinder to a separator (32). The pressure of the removed steam is controlled by a steam pressure control valve (36) and the rate of condensate removal is monitored by a condensate removal monitor (48). A computer controller (16) adjusts the steam feed and removal pressure control valves to maintain the smallest differential pressure therebetween which will maintain the condensate removal rate substantially constant. The computer controller sets an initial pressure differential during an initializing step (50). In a first pressure differential adjustment step (52), the computer decreases the pressured differential in first increments until the condensate removal rate begins to decrease. In response to the decrease, the first pressure differential adjusting step increases the pressure differential by the first increment.

Abstract: This fishing lure is heavier than water or has a greater specific gravity than water and thus, the same will sink in water to be fished. The lure has an elongated body having two spaced apart, parallel, side surface portions and two end surface portions connected with said side surface portions. Each side surface face connects with one end surface portion at an acute angle and with the other end surface at an obtuse angle. The opposite side surface face connects with the one end surface portion at an obtuse angle and with the other end portion at an acute angle. The lure body tapers toward both ends and thus the mid portion is sufficiently relatively heavy so that in sinking, the lure remains substantially level and does not sink with either end portion pointing downwardly. As the lure body tends to remain level as the same sinks, the acute angle between an end surface portion and a side surface member facilitates turning or angular movement of the fishing lure about its longitudinal axis as the same sinks.
