Abstract: A control panel for an ADF including a series of buttons or actuators arranged in a grid-like array having two rows and three columns and a series of LEDs vertically aligned with one another and located adjacent to the array of buttons. The LEDs may be more centrally located between the first and second sides of the ADF, while the array of buttons may be located more proximate to the second side of the ADF. The control panel may be disposed more proximate to the bottom side of the ADF than the top side of the ADF. Each of the buttons of the array of buttons may extend or protrude from the surface of the control panel. The spacing, arrangement, size, and protruding nature of each of the buttons enables a user wearing welding gloves to easily locate and operate the control panel of the ADF.

Abstract: Sanitary elements and cartridges of high performance are described which utilize a thin surrounding tubular shell with an exterior textured surface. Through the use of an overwrap material of particular design and by wrapping an assemblage of sheets of semipermeable membrane material, permeate carrier material and feed spacer material using a high tension, a spirally wound crossflow filtration element is constructed which has a substantially cylindrical outer surface of closely controlled OD that smoothly fits within such shell and which resists telescoping as a result of its radial compression.
