Patent number: 11058973Abstract: An underdrain assembly for filtering particulates from a fluid having an upper structure connected to a bottom plate. At least one flow control vane is positioned between the upper structure and the bottom plate for directing and managing fluid flow through the assembly. The upper structure can have first and second filtration members, the second filtration member positioned between the first filtration member and the bottom plate. The second filtration member can have a shape that restricts fluid flow within the underdrain. The underdrain can have air and water inlets. The water inlet can have an end with a plate covering an upper portion thereof. The end can also include an opening having an angular cut forming an angle with respect to a longitudinal axis of the water inlet. Thus arranged, air is prevented from migrating out the water line. A resilient mounting arrangement for the underdrain is also disclosed.Type: GrantFiled: December 11, 2018Date of Patent: July 13, 2021Assignee: Aqseptence Group, Inc.Inventors: Michael Richard Ekholm, Richard Charles Maxson, Mark Edgar Watson, Fabrice Jean Alphonse Courageot

Patent number: 6701864Abstract: The present invention is directed toward a residual life indicator. The residual life indicator comprises a solid, surface active, waterproof support medium having a concentric pattern imprinted thereon. The concentric pattern comprises a center pattern and at least one outer pattern. An indicator dye spot is disposed within the center pattern of the concentric patter. When the indicator dye is exposed to contaminants, the indicator dye spot visually moves toward the outer pattern.Type: GrantFiled: September 30, 2002Date of Patent: March 9, 2004Assignee: Scentczar CorporationInventors: Edgar Watson, Jr., Timothy W. Caraher, Mindy R. Bennett, Joseph E. Roehl, Mark J. Greenfield, Amber J. Ericsson

Patent number: 5646736Abstract: An instrument kit includes a photometric instrument and a standardizing ampoule. The standardizing ampoule includes a machine readable code that is recognized by the instrument when the ampoule is inserted to initiate a standardizing routine. An analysis kit includes an optical filter assembly and a sample ampoule to be used with the instrument. The filter assembly also includes a machine readable code that is detected by the instrument when inserted to identify the particular test to be conducted by the instrument. The instrument automatically applies the relationship between detected light and concentration of a substance for the particular test and displays the sample concentration in numeric digital form. The instrument operates automatically, and there are no buttons or other external input devices.Type: GrantFiled: December 19, 1995Date of Patent: July 8, 1997Assignee: CHEMetrics, Inc.Inventors: Gordon A. Rampy, Rame Bull, Henry Castaneda, Teresa A. Neale, G. Neil Spokes, Edgar Watson, Jr.
