Abstract: A second reaction medium is introduced into a first reaction medium flowing in a flow channel and the reaction media are intensively mixed. The second reaction medium (which may be one or more reaction media) is introduced at a plurality or even a multiplicity of positions that are distributed over a cross section of the flow channel. Turbulence flow is induced in the first reaction medium (which may also be one or more reaction media) at the positions where the second reaction medium is introduced. As a result, the intense mixing of the reaction media with one another takes place directly at the locations where the second reaction medium is introduced into the flow channel.

Abstract: In a variable phased valve lifter of an internal combustion engine, a roller lifter is allowed to move along a constraining member of a constraining mechanism, and the constraining mechanism is allowed to move freely in a direction substantially parallel to a line perpendicular to the flat surface machined onto the roller lifter. As the roller lifter moves through its arcuate path, the parallel flat surface(s) of the roller lifter will slide across the constraining member(s) of the constraining mechanism, and end members of the constraining mechanism slide fore-and-aft within stationary blocks. The roller lifter is thus prevented from rotating about its longitudinal axis as it moves in arcuate fashion in cooperation with the constraining mechanism, maintaining line contact between the roller and cam lobe of the camshaft.

Abstract: A heat exchanger in which dead zones and areas of stagnation are significantly minimized or eliminated. The heat exchanger includes at least one floating tubesheet which is movable in a longitudinal direction in response to tube expansion and contraction relative to the heat exchanger shell. The shell is joined to the ends by conical members which preferably join onto the shell at a distance along its length to provide shell extensions which promote better flow patterns in the regions of the tube ends. Tube erosion may be addressed by providing a sacrificial portion of tube length extending beyond the tube sheets so as to make repair and replacement of the eroded portion of tubes significantly cheaper, easier and with minimal process interruption. Because axial or longitudinal flow is employed with respect to the shell-side fluid, tube vibration problems are generally eliminated and fouling is minimized through the use of high fluid velocities.
