Title: Method and apparatus for adjusting the boundary surface between two controllably flowing and mutually separable solutions and for conducting both solutions out of the separation part
Inventor: TAIPALE PETRI
IPC: B01D11/04
Filed: 1997-04-29
Abstract: The invention relates to a method for adjusting the boundary surface between the two mutually separable solutions in liquid-liquid extraction at the discharge end of the separation part and for preventing the aeration of the solutions when discharging them from the separation part, so that the overflow height of the settled, lighter organic solution is maintained constant. In order to adjust the boundary surface in between the mutually separable solutions, the overflow height of the heavier aqueous solution is adjusted by conducting the settled aqueous solution from down upwards through tubular elements, in which case the height of these overflow pipes can be adjusted. The aeration of the solutions when discharging them from the separation part is prevented by conducting the solutions into transfer pipes through covered, shaft-like weir boxes that are deeper than the discharge end. The invention also relates to an apparatus whereby the boundary surface between the solutions is adjusted and the areation prevented.

Abstract: This invention relates to apparatus used in supporting safety rails and discloses a system in which a safety rail post support and security device is used in pairs or greater multiples to hold pieces of as a safety rail at the edge of an elevated surface and is speedily attached to or detached from the three commonly found roof edge structures, that is, roofs that are flat right up to the edge, roofs that have a very low ledge or flashing around the perimeter, and roofs that have a parapet along the edge. Previous systems rely on cantilever weights positioned well in from the edge of the roof, interfering with the work to be done there. The post support and security device has a junction piece comprising four intersecting extruded stabilizer bars perpendicular to each other in one plane and a fifth bar protruding from that plane at ninety degrees.

The upright post has two brackets, each adapted to hold one or two 10 foot 2 by 4 inch lumber rails. The adaptable safety rail system of the present invention for flat roofs and parapets exceeds typical safety barrier standards for workers on such roofs.
