Abstract: A container for receiving and holding effluent water containing oil/grease to be removed including a sealed enclosure. In one example, a cover supports a partially immersed rotatable disk; a drive on the main sectional cover rotates the disk; a trough on the main sectional cover straddles the disk; and a blade on the trough scrapes a side of the disk, to direct oil and grease from the disk along the scraper blade along the trough for collection in a storage container. Efficiencies of construction of the sectional covers, disk and a sensor probe are disclosed in some examples. Also disclosed are apparatus, system and methods for a sealed container for receiving and holding effluent water containing oil/grease to be removed.

Abstract: Systems and methods are provided for automated evaluation of performance of a shooter at a shooting range. An automated shooting evaluation system may include a target carrier, a vision system, a control computer, and a user interface. The target carrier can secure a target. The vision system can be fixed relative to the target carrier to capture image data of a target secured by the target carrier and can include an imaging device and processor(s) to receive and process image data captured by the image device to identify the target and, further, to identify changes to the target. The vision system can transmit a position of a detected bullet hole to the user interface, which can display a bullet hole indicator superimposed on a digital representation of the target. An automated shooting evaluation system can also include a shot-fired detector to detect whether a shot is fired at the target and to communicate shot-fired detection data to the user interface.

Abstract: An apparatus for separating FOG from grey water in an effluent includes a housing having a first end having two plumbing fittings and a second end having one plumbing fitting. A baffle mounted inside the housing at the second end forms a barrier to flow of liquid toward the plumbing fitting on the second end above a certain height, and allows the flow of liquid past the barrier toward the plumbing fitting on the second end below the certain height. A conduit allows flow of liquid from past the baffle to one of the plumbing fittings on the first end. A plug closes one of the three plumbing fittings, and leaves the other two plumbing fittings available for connection to plumbing from a source of effluent and an outlet for grey water, respectively.

Abstract: A kit of materials to make a support for one or more manhole rings during a concrete pour around a prefabricated grease interceptor includes a base, a plurality of vertical supports, and a peripheral grid to surround a top of the prefabricated grease interceptor at a position to support a manhole seating ring. The vertical supports are long enough that they extend from the base to the peripheral grid for most grease interceptor installations or can be cut to size to position the peripheral grid.
