| 20090014369 | Friction profile for the top of pool grate bars - An inventive top profile design of friction ridges on top of grate bars in a swimming pool. The profiles exhibit a multiple of right angled friction ridges which are stacked within each other in a direction which is perpendicular to the longitudinal direction of the grate bars. The right angled ridges resemble the well known chevron format. The right angled friction ridges increase the coefficient of friction to above 1.0 ASTM. The design of the friction ridges drains off water quickly and reduces the travel time of water the grate bars. The design also prevents stagnant water forming any mold formation. The tops of the friction ridges are rounded so that no sharp edges are present to enhance the comfort under the bare feet. | 01-15-2009 |

| 20110000837 | Multiple Inlet flow regulator - A multiple inlet flow regulator with a restricted low-level inlet and upper-level overflow inlet is used to modify a new or existing storm water catch basin to regulate the flow of storm water from the catch basin into the sewer system. During periods of heavy rains and high flows into the catch basin, this flow regulator will allow the catch basin to serve as a temporary storage tank for storm water. The construction of these flow regulators can be accomplished using a variety of off-the-shelf components or custom fabrication, to achieve the desired effect of restricting the discharge from each catch basin in a combined sewer or storm water system as much as practicable without resulting in overflows onto the roadways. Key components include: restricted low level inlet that can be adapted in size to meet specific low flow conditions, upper level inlet sized to allow for the maximum discharge from the catch basin to prevent overflows onto the roadway, connections to the existing catch basin structure and covers to prevent floatable debris from discharging from the catch basin into the sewer system. | 01-06-2011 |

| 20090095667 | STEEL DRAIN WITH AUTOMATIC CLOSER - Cleaning operations involving steam and flushing with water produce runoff that flows into drains installed in factory floors. Allowing bulky materials to flow into and plugging factory drains creates floor flooding conditions, production line shutdown and loss of time and money. These conditions can occur when strainer baskets are removed from drains. A drain facilitated with a drain closer prevents flow of bulky materials into drains and subsequent plugging. The drain closer is activated with a modified strainer basket such that removal of the basket closes the drain preventing inflow of bulky materials. | 04-16-2009 |
