Abstract: Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media can be supported by a screen above a floor in a vault allows for incoming storm water to pass into a void space above the floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. A top screen can be placed on top of the filtration media. Layers of river rocks can be placed on top of and below the filtration media. The captured debris can drop to the floor. The long lasting filtration media can be cleaned by being backwashed.

Abstract: Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media supported by a screen above an angled floor in a vault allows for incoming storm water to pass into a void space above the angled floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. Water sprayers can further liquefy sediment and debris that fills the void space between the angled floor and the bottom of the screen. The captured debris can slide down the angled floor, where a vacuum hose from an above ground vacuum truck can remove the debris and sediment. The long lasting filtration media can be cleaned by being backwashed.

Abstract: The present invention relates to a temporary grate cover apparatus for placement over a storm water grate to filter sediment and trash from entering the storm drain during a construction project and to a method of making and attaching a storm water grate cover to a storm water grate.

Abstract: An in-line storm water drain system and a filter basket for a storm water drain system are provided in which the storm water drain system has a housing having an inlet and outlet thereinto and interior walls forming a plurality of chambers therein. The filter basket has a rigid frame and a plurality of screened sides and is attached to the interior walls. The filter basket has a pair of top screen filter doors and a pair of bottom screen filter doors to allow entry into the filter basket and on through to the bottom of the filter basket for cleaning the chambers. An inlet feed chute is attached to the filter basket open end and also has a screen bottom door and directs water from the housing inlet to and through the filter basket while collecting debris in the basket.

Abstract: A storm water filter system for filtering storm water being fed into an in-ground well includes a housing having an inlet and an outlet, with the outlet being connected to an in-ground recharge well. A plurality of open chambers are formed in the housing. An inlet filter box has an open end located in the housing and positioned with the open end facing the housing inlet. An outlet screen filter is positioned over the outlet for capturing debris from water entering the outlet and has a bypass for water to pass when the filter becomes partially blocked.

Abstract: A street curb filter apparatus can be attached to a street curb side adjacent a manhole to collect storm water runoff from the curbside and direct the collected storm water through a filter basket. The street curb filter has a street curb shelf with a water channel on the surface thereof and filter basket supporting arms. The filter basket supporting arms are positioned to receive collected storm water runoff from the water channels in the street curb shelf. The filter basket is shaped to fit into a storm water manhole opening and is removably attached to the street curb shelf filter basket arms to receive storm water runoff from the water channeling surface.

Abstract: A method of making a golf course green drainage system and the system made from the process which includes forming a drainage system field in a golf course green and coupling a drain pipe to the drain field for channeling water collected from the drain field. The process includes selecting a filter system having an inlet and a discharge for filtering water from the golf course green drainage field and placing the selected filter underground remotely from the golf course green and connecting the drain pipe thereto. The filter system discharge is connected to a retention pond so that water collected on a golf course green drainage field is filtered prior to being fed into the retention pond. The process includes selecting a filter having a housing and a hydrocarbon absorbent filter medium therein having a filter screen covering over the hydrocarbon absorbent medium and having a water deflector adjacent the inlet.

Abstract: A system for restoring an interrupted switched connection between subscribers in a communications network includes a first transfer node for transmitting and receiving signals in the communications network, and a second transfer node for transmitting and receiving signals in the communications network. A network controller establishes a protected channel between the first and second transfer nodes, establishes a switched connection between the first and second transfer nodes in the protected channel, and restores the switched connection by restoring the protected channel if the switched connection is interrupted as a result of an interruption in the protected channel.

Abstract: An outboard motor drive shaft housing attachment apparatus includes at least one extended fin plate, having a raised front portion and a pair of angled side portion and an attachment bar shaped to fit an opening in the outboard motor shaft housing. The attachment bar is passed through the opening in the shaft housing and removably attached to the fin plate with fasteners. Additional fasteners are used to attach the fin plate to the outboard motor shaft housing. The fin plate can have anti-skid steps formed thereon and a sacrificial anode attached thereto. A method of attaching an outboard motor attachment, comprises the steps of removing the outboard drive shaft housing sacrificial anode to leave an opening through the housing; sliding a shaft through the opening in the housing created by the removal of the sacrificial anode; attaching a fin plate to the shaft extending through the shaft housing opening; and then attaching the fin plate directly to the housing with threaded fasteners.

Abstract: A substantially continuous flow is attained in the unloading of a bulk particulate from a storage hopper by monitoring the pressure differential between the hopper and a point in the discharge line downstream of the hopper outlet. The pressure differential is sensed by a pressure switch in the discharge line which activates a vibrator on the hopper near the outlet when the differential is at a first predetermined value and deactivates the vibrator when the differential is at a second predetermined value, thereby maintaining the flow and reducing mechanical damage to the hopper.
